Product Description: As an indispensable equipment in industrial fluid handling, the stability and durability of the slurry pump directly affect production efficiency and safety. During long-term operation, the long shaft of the slurry pump often suffers surface damage due to factors such as material wear and corrosion, which in turn affects the overall performance of the pump. The emergence of laser cladding processing technology has solved this problem, making it an ideal choice for repairing and strengthening the long shaft of slurry pumps.I. Overview of Laser Cladding Processing TechnologyLaser cladding processing technology is a technique that uses a high-energy laser beam as a heat source to rapidly melt cladding materials and form a metallurgical bond with the substrate. It can repair, strengthen, and modify surfaces without altering the original dimensions and properties of the substrate. Compared to traditional surface repair technologies such as welding and spraying, laser cladding processing technology offers advantages such as fast heating speed, small heat-affected zone, minimal deformation, and low dilution rate. As a result, it is widely used in aerospace, automotive, mold, and other fields.II. Advantages of Laser Cladding Processing for Slurry Pump Long Shafts1. Precise Control: Laser cladding processing technology enables precise control of the cladding layer, including its thickness, composition, and microstructure. This allows for personalized design based on actual requirements when repairing slurry pump long shafts, ensuring optimal performance after repair.2. High Efficiency and Energy Savings: During the laser cladding process, the laser beam's concentrated energy and fast heating speed allow the cladding material to melt rapidly and form a metallurgical bond with the substrate in a short time. This efficient processing method significantly reduces repair time and improves production efficiency.3. Reliable Quality: Due to the high energy density of the laser beam and the small heat-affected zone, the residual stress and deformation generated during the laser cladding process are relatively small. This helps ensure that the repaired slurry pump long shaft has higher reliability and stability.4. Environmentally Friendly and Pollution-Free: The laser cladding process does not require the addition of any chemical agents or filler materials, so it does not produce harmful gases or waste residues. This environmentally friendly processing method aligns with the requirements of modern industrial sustainable development.III. Process Flow of Laser Cladding Processing for Slurry Pump Long ShaftsThe process flow of laser cladding processing for slurry pump long shafts mainly includes the following steps:1. Preliminary Preparation: Perform pre-treatment work such as cleaning, rust removal, and polishing on the slurry pump long shaft to ensure the bonding quality between the cladding layer and the substrate. At the same time, select appropriate cladding materials and process parameters based on actual needs.2. Cladding Layer Design: Design a reasonable cladding layer structure and composition based on the damage condition and performance requirements of the slurry pump long shaft. This includes determining parameters such as the thickness, shape, and distribution of the cladding layer.3. Laser Cladding Processing: Place the cladding material on the surface of the slurry pump long shaft and use a high-energy laser beam for heating and melting. Under the action of the laser beam, the cladding material rapidly melts and forms a metallurgical bond with the substrate. Precise control of the cladding layer is achieved by adjusting parameters such as the laser beam's moving speed and power.4. Post-Processing: Perform post-processing work such as cooling, polishing, and inspection on the cladded slurry pump long shaft. This includes removing excess cladding material and defects such as burrs, as well as testing the performance of the cladding layer in terms of hardness, wear resistance, and corrosion resistance.IV. Application Case of Laser Cladding Processing for Slurry Pump Long ShaftsA chemical plant discovered severe wear and corrosion on the surface of the long shaft of its slurry pump during long-term use. To restore the pump's performance and extend its service life, the plant decided to use laser cladding processing technology to repair the long shaft. After careful design and processing, the repaired long shaft exhibited a smooth surface, high hardness, excellent wear resistance, and strong corrosion resistance. During actual operation, the repaired slurry pump demonstrated stable and reliable performance, effectively improving production efficiency and reducing maintenance costs.V. Conclusion and OutlookWith the continuous development and advancement of industrial technology, laser cladding processing technology will play an increasingly important role in the field of slurry pump long shaft repair. In the future, with continuous innovation and improvement in laser technology, as well as the emergence and application of new cladding materials, laser cladding processing technology will have broader application prospects and higher performance requirements. At the same time, we must continue to learn and explore new technologies and methods to address increasingly complex industrial environments and challenges. more>

Company: Shaanxi Bomingyang Sealing Technology Co., Ltd.

Product Description: Company Introduction: Bomingyang Technology Co., Ltd., located in Xi'an, Shaanxi Province, is a technology-based enterprise integrating the R&D, production, and sales of rubber seals. The company mainly produces various rubber seals such as O-rings, X-rings, Y-rings, flat washers, V-rings, ED rings, C-rings, rubber strips, rubber balls, rubber retaining rings, and miscellaneous rubber parts.       Due to different environmental and application conditions, the materials used for rubber seals vary, which determines the specific environments and occasions for which the developed and produced seals are suitable.       In the industry, common rubber materials for R&D and production of seals include NBR rubber, acrylic ester, and fluororubber. Besides rubber, other materials such as silicone rubber, polyurethane, HNBR rubber, and PTFE rubber (used for seal lip parts) can also be selected.       Food-grade rubber O-rings, simply put, are O-rings produced using food-grade rubber raw materials, primarily emphasizing environmental performance. Materials typically include NBR rubber, silicone rubber, EPDM rubber, natural rubber, neoprene, fluororubber, etc., with silicone rubber being the most commonly used. Food-grade silicone rubber is formed through the condensation polymerization of silicate inorganic polymer gel materials, composed of over 98% silicon dioxide. It is non-toxic, odorless, chemically stable, and does not react with acids, alkalis, or salts. Due to its colloidal structure with numerous micropores and a large specific surface area, food-grade silicone rubber has a pore size of about 8–10 nm and a specific surface area of 300–500 m²/g. It exhibits strong water absorption, capable of absorbing 8–10 times its weight under high humidity conditions. Thus, it can be used as a desiccant for food and external applications. Food-grade silicone rubber is a refined, non-toxic product that can be directly mixed into food to ensure dryness and consumed with food without any adverse effects on human health.Main Applications of Food-Grade Rubber O-Rings:1. Equipment connection pipelines, conduits, etc.;2. Baby bottle straws, conduits, etc.;3. Mechanical products such as bread makers, sterilizers, water dispensers, kettles, irons, rice cookers, fryers, juicers, and gas appliances; machinery, electrical, and electronics industries;4. Connection pipes for food machinery; tubular products for food applications;5. Connection pipes and conduits for water dispensers, coffee makers, children's sippy cups, etc.;6. Sealing for construction, transportation, electronic instruments, and components.Key Performance Characteristics of Food-Grade Rubber O-Rings:1. Non-toxic, odorless, and highly environmentally friendly;2. Soft, elastic, resistant to twisting and deformation;3. Crack-resistant, long service life, resistant to cold and high temperatures;4. Higher tear strength and excellent electrical properties;5. Does not yellow, bloom, turn white, or fade when stored at room temperature; does not form scale or develop odors when immersed in water for extended periods.Advantages of Rubber O-Rings Compared to Other Seal Types:1. Suitable for various sealing forms: static sealing, dynamic sealing;Compatible with a wide range of materials, with standardized sizes and grooves for strong interchangeability.2. Suitable for multiple motion types: rotary motion, axial reciprocating motion, or combined motions (e.g., rotary-reciprocating combined motion).3. Compatible with various sealing media: oil, water, gas, chemical media, or other mixed media.By selecting appropriate rubber materials and formulations, effective sealing for oil, water, air, gas, and various chemical media can be achieved. Wide temperature range (-60°C to +220°C); static pressure resistance up to 1500 kg/cm² (when used with reinforcing rings).4. Simple design, compact structure, easy installation and removal.The cross-section structure of rubber O-rings is extremely simple, with self-sealing capabilities and reliable sealing performance. Due to the simplicity of both the O-ring itself and its installation structure, along with standardization, installation and replacement are very easy.5. Low cost.Hardness selection for rubber O-rings is crucial. For example, a pump turbine at a power station using 70 Shore hardness seals experienced frequent peeling and even transverse cutting. Switching to 85–90 Shore hardness seals yielded ideal results.Lower hardness facilitates installation but may lead to peeling, installation damage, extrusion, or pressure issues. Excessive hardness complicates installation.Typically, rubber O-ring hardness ranges from 40 to 90 IRHD, with 70 IRHD being generally suitable. Silicone rubber is an exception, usually used at 60 IRHD.6. Wide variety of materials.Materials can be selected based on different fluids: NBR, fluororubber (FKM), silicone rubber (SIL), EPDM, neoprene (CR), natural rubber (NR), HNBR, butyl rubber (IIR), fluorosilicone rubber (FLS), etc.After-Sales Service: All company products come with material certifications.

Product Description: Zhengzhou Yixin Kiln Co., Ltd. supplies 1700-type and 1800-type silicon molybdenum rods. Specific products include U-type silicon molybdenum rods, U-type right-angle silicon molybdenum rods (L-type silicon molybdenum rods), I-type (straight) silicon molybdenum rods, new process hot-bent right-angle silicon molybdenum rods, cold-bent right-angle silicon molybdenum rods, press-bent silicon molybdenum rods, and special-shaped silicon molybdenum rods (circular, W-type, spiral, multi-bend, etc.). Customized silicon molybdenum rods of different shapes can be developed according to customer requirements. Welcome to call.When silicon molybdenum rods are heated above 1200°C in an oxidizing atmosphere, the following reaction occurs: 2MoSi2 + 7O2 → 2MoO3↑ + 4SiO2MoO3 volatilizes, and SiO2 adheres to the surface of the element, forming a dense quartz glass film that protects the substrate from further oxidation. Therefore, silicon molybdenum rods have excellent oxidation resistance, with a rated operating temperature of up to 1700°C in an oxidizing atmosphere (below the melting point of quartz, 1713°C). If the SiO2 film is damaged due to mechanical or chemical factors, it will automatically regenerate during use.Suitable for operation in air, nitrogen, carbon dioxide, and inert gases (helium, neon, argon), it also performs well in reducing atmospheres (CO, decomposed ammonia, and hydrocarbons). Water vapor is harmless to it, while hydrogen can damage its protective film and form a hydrocarbon compound. However, it can still be used at temperatures below 1350°C. The lower the dew point of hydrogen (i.e., the lower the moisture content), the lower the allowable operating temperature of the silicon molybdenum rod. Sulfur, fluorine, chlorine, and alkalis are harmful to the element, and acids react with the element, so contact should be avoided.Silicon molybdenum rods are environmentally friendly, energy-saving, easy to install and replace, and highly heat-resistant. They are widely used in electric furnaces at 1400-1700°C, such as tube furnaces, box furnaces, atmosphere furnaces, push-plate kilns, tunnel kilns, lift furnaces, and muffle furnaces. more>

Product Description: Non-Detaching Screw NutApplied to panel screws: Non-detaching screws, also known as spring screws. Non-detaching screws can be riveted onto iron plates, allowing free screwing in and out. The entire assembly remains securely embedded in the panel without detaching, hence also called non-falling screws. The outer hand-twist sleeve is typically embossed with straight knurls for easy hand-tightening or manual fastening, so it is also referred to as hand-tight screws or hand-twist screws.Non-detaching panel screws (spring screws) can be used for installing PCB boards, occupying minimal space. The hand-tight screw's press-rivet sleeve features knurled teeth, pressed into the chassis or thin sheet holes (note: the drilled hole diameter of the thin sheet must meet specific requirements relative to the press-tooth diameter of the spring screw), forming an exposed spring screw that is hand-twisted at the other end (i.e., the hand-twist end). Due to the internal fixed spring, the screw moves in and out relative to the other end of the thin sheet. This solution addresses the challenge of frequently needing to remove screws and is very convenient and practical.Name: Non-detaching screw, panel screw, spring hand-tight screwMaterial: Combination of carbon steel screw, carbon steel press-rivet sleeve, and aluminum hand-twist sleeve; combination of stainless steel screw, stainless steel press-rivet sleeve, and aluminum hand-twist sleeve. The non-detaching panel screws produced by Yaoda Hardware*** are entirely manufactured and assembled in-house, except for the spring, which is outsourced, with strict quality control.The panel spring screw (non-detaching screw) consists of several components:1. Screw part (used to fasten the other end of the chassis thin sheet; typically made of carbon steel or stainless steel, with cross or slotted head for tool tightening)2. Hand-twist sleeve (usually knurled with straight patterns, typically made of aluminum, sometimes anodized black as needed)3. Press-rivet sleeve (used for riveting onto the panel)4. Spring (facilitates the extension and retraction of the screw and prevents the entire assembly from detaching)After each component is produced, they are assembled into one unit, and the hand-twist part is pressed to fit together with the press-rivet part via the spring, forming a complete non-detaching spring panel screw.PF21 Type PF22 Type Press-in Style Panel Fastener   Assemblies PF21 PF22PF21-M3-12.3PF21-M3-14PF21-M3-15.5PF21-M3-17.1PF21-M3.5-16.4PF21-M3.5-18PF21-M3.5-19.6PF21-M3.5-21.2PF21-M4-16.9PF21-M4-18.5PF21-M4-20PF21-M4-21.6PF21-M5-16.9PF21-M5-18.5PF21-M5-20PF21-M5-21.6PF21-M6-20.5PF21-M6-22.1PF21-M6-23.7PF21-M6-25.3PF21-440-12.3PF21-440-14PF21-440-15.5PF21-440-17.1PF21-632-16.4PF21-632-18PF21-632-19.6PF21-632-21.2PF21-832-16.9PF21-832-18.5PF21-832-20PF21-832-21.6PF21-032-16.9PF21-032-18.5PF21-032-20PF21-032-21.6PF22-M3.5-16.4PF22-M3.5-18PF22-M4-20PF22-M3.5-21.2PF22-M4-16.9PF22-M4-18.5PF22-M5-20PF22-M4-21.6PF22-M5-16.9PF22-M5-18.5PF22-M6-23.7PF22-M5-21.6PF22-M6-20.5PF22-M6-22.1PF22-440-15.5PF22-M6-25.3PF22-440-12.3PF22-440-14PF22-632-19.6PF22-440-17.1PF22-632-16.4PF22-632-18PF22-832-20PF22-632-21.2PF22-832-16.9PF22-832-18.5PF22-032-20PF22-832-21.6PF22-032-16.9PF22-032-18.5PF22-0420-23.7PF22-032-21.6PF22-0420-20.5PF22-0420-22.1PF22-0420-25.3 more>

Product Description:         Silicon molybdenum rods are available in two types: 1700 and 1800. The 1700 type uses the old process, while the 1800 type uses the new process. The main differences between them lie in the molybdenum content and the production process. The new process adopts a hot bending technique, allowing the rods to be bent freely to meet the special requirements of different customers. This enables selection based on production needs and appropriately reduces production costs. The price of the new process silicon molybdenum rods is higher than that of the old process for the same specifications.       Silicon molybdenum rod heating elements are suitable for use in air and neutral atmospheres. Reducing atmospheres such as hydrogen can damage the protective layer, while vapors of chlorine and sulfur can cause direct harm to the elements.The screws on the silicon molybdenum rod fixtures should not be tightened too much at once. The conductive wires should be in close contact with the white aluminum-sprayed parts of the cold ends of the rods to prevent sparking. When the elements reach high temperatures, tighten the screws again, as the elements become somewhat plastic and are less prone to breakage at this stage.At room temperature, silicon molybdenum rods have low bending strength and cannot withstand impact. Protective measures should be taken during installation to avoid breakage due to external pressure.       Regularly check whether the connections at various points of the silicon molybdenum rod heating elements are secure, and ensure that the electrical connections in the furnace temperature control system are in good condition.    more>
