When the motor drives the outer magnet of the magnetic coupler to rotate, the magnetic field lines pass through the gap and isolation sleeve, acting on the inner magnet to synchronize the pump rotor with the motor rotation, transmitting torque without mechanical contact. Since the liquid is enclosed within the isolation sleeve, material leakage is completely eliminated, reducing pollution, saving energy, purifying the environment, and protecting the physical and mental health of production line personnel.Main FeaturesAs environmental protection receives increasing global attention and corresponding environmental regulations are enacted and implemented, combined with the medium conditions of many domestic users and the domestic production process of fluoroplastic-lined magnetic pumps, our company has organized R&D personnel to develop a new generation of fluoroplastic-lined magnetic pumps with the following features:1. The pump body lining, impeller inner rotor, and isolation sleeve are all made of pure F46 material through one-time molding, with no impurities precipitated, making them highly suitable for conveying high-purity, highly corrosive chemical liquids;2. The pump casing is made of ductile iron, and the pump body is designed according to national standard flanges, ensuring excellent mechanical strength and the ability to withstand heavy pipeline loads;3. The flow-passing components are lined with F46 material, featuring smooth and unobstructed flow channels, superior hydraulic performance, low hydraulic friction loss, and high efficiency;4. The pump shaft, bearing sleeve, and dynamic/static rings are made of pressureless sintered silicon carbide, offering high hardness, high wear resistance, and high corrosion resistance;5. The unique spiral groove design in the bearing sleeve’s inner hole facilitates easier lubrication of the sliding bearing pair and more efficient dissipation of heat generated by friction during pump operation;6. An additional reinforcement cover made of imported material is added outside the isolation sleeve, enabling the pump unit to withstand higher system pressures and eliminating heat generated by magnetic eddy currents in metal sleeves;7. The inner and outer magnets are made of neodymium iron boron and samarium cobalt materials, with a magnetic field strength of up to 3600 Gauss on the magnet surface, ensuring smooth transmission of the prime mover’s torque to the impeller without slipping even under high-flow conditions. This also prevents contact between the inner rotor and the rear thrust ring, avoiding friction-induced heat that could melt fluoroplastic components and ensuring the magnetic pump operates reliably in highly corrosive environments;8. The entire pump unit adopts a rear-pull structure, allowing one person to perform internal maintenance and part replacement without the need to disassemble pipelines.Scope of Use and ApplicationsFluoroplastic-lined magnetic pumps can convey any concentration of sulfuric acid, hydrochloric acid, nitric acid, strong alkalis, aqua regia, hydrofluoric acid, strong oxidizers, reducing agents, and other highly corrosive media without damage, as long as the fluid contains no suspended particles and the temperature is below 140°C. They are the preferred product for chemical, petroleum, oil refining, nuclear power, chemical products, electroplating, electrolysis, chemical fibers, fertilizers, pharmaceuticals, nuclear power, highly toxic, flammable, explosive, and other precious liquid processing industries. more>

Company: 苏州世纪行工业科技有限公司

Product Description: A flameless venting device is a safety apparatus used to protect equipment and personnel. It automatically shuts down equipment or pipelines in the event of an explosion or fire, preventing the spread of flames or the escalation of an explosion. Its working principle involves detecting changes in gas pressure and temperature inside pipelines or equipment to determine whether there is a risk of explosion or fire. If a hazard is confirmed, it immediately shuts down the equipment or pipeline while releasing pressure to achieve the goal of protecting both equipment and personnel.Dust Explosion Relief Valve for Dust Collector Pipelines (Flameless Venting Device)Brief Introduction:1. It consists of two parts: a venting panel and a flame extinguishing module;2. Suitable for flameless venting of dust explosions in indoor equipment. It offers high venting efficiency and is cost-effective;3. Effectively prevents flames and heat, providing a safe environment for equipment, buildings, and personnel. It also collects dust effectively, reducing environmental pollution;4. When used in combination with an isolation valve, it not only prevents pressure waves and flames from propagating to upstream workshop areas but also suppresses secondary explosions, reducing property damage and ensuring personnel safety.Product Parameters:Static opening pressure: 0.01 MPa;Frame material: Carbon steel or stainless steel;Flame-retardant material: 304SS;Applicable dust: St1 and St2 dust with Kst ≤ 300 barg*m/s, with effective venting area meeting explosion relief requirements;Product classification: Depending on the working conditions, it can be divided into rectangular flameless venting devices and curved flameless venting devices;Applicable equipment: Dust collectors, bucket elevators, drying equipment, cyclone separators, dust collectors;Industries: Wood processing, plastics, spraying, food and dairy, plastic and dye processing, grain storage and processing, pharmaceuticals, coal processing, brewing, chemicals, metal processing, chemicals, power, cement, and other industries.Dust Explosion Relief Valve for Dust Collector Pipelines (Flameless Venting Device)Working Principle:The flameless venting device consists of two parts—an explosion-proof panel and a fire extinguishing module. The explosion-proof panel responds to the rapid increase in deflagration pressure, immediately opening to reduce pressure. When the expanding fireball passes through the open explosion-proof panel, it is intercepted by the fire extinguishing module. The precision stainless steel mesh supported by the frame acts as a three-dimensional flame trap, extinguishing the flame and ensuring it does not propagate, thereby preventing secondary or multiple explosions. The fire extinguishing module eliminates deflagration flames, reduces the temperature of hot gases, and captures both burning and unburned dust passing through the open explosion-proof panel.At the same time, pressure waves or noise generated by production equipment are also minimized. As flames pass through the mesh flame-retardant element, heat exchange occurs between the element and the flame, rapidly cooling the high-temperature flame, releasing pressure and smoke. Additionally, pressure waves or noise generated by production equipment are reduced.Application Areas:Widely used in industries such as grain, metallurgy, chemicals, power, light industry, tobacco, pharmaceuticals, mechanical processing, and solid waste treatment. Applicable equipment includes cyclone separators, bag dust collectors, dust collectors, cartridge filters, pneumatic conveying systems, rod or ball mills, bucket elevators, dryers and ovens, roller mills, and buildings.With increasingly stringent environmental inspections, safety is gaining more attention. In the past, venting panels were commonly installed on dust collectors to release overpressure caused by dust explosions. However, installing such devices indoors is not permitted by safety regulations, as it poses risks to surrounding personnel and equipment. The pressure waves and flames from explosions may cause secondary or multiple explosions, creating hazards. Therefore, relying solely on explosion-proof panels for dust collectors is unreliable. We recommend using flameless venting + isolation technology (a more economical solution) or explosion suppression + isolation technology to ensure production safety.There are three main methods for dust explosion protection: venting, isolation, and suppression.Venting: Releases explosion pressure in advance through a pressure relief device to protect equipment from damage.Isolation: Blocks explosions using an isolation valve to prevent flame propagation.Suppression: Detects sparks using detection devices, then activates fire extinguishing systems to instantly extinguish flames and prevent explosions. more>

Product Description: Brass Rod:Brass rods are a type of non-ferrous metal processed bar, known for their excellent machinability and high electrical conductivity. They are mainly categorized into brass rods (copper-zinc alloy, relatively cheaper) and copper rods (higher copper content).Brass rods are bar-shaped objects made from an alloy of copper and zinc, named for their yellow color. Brass with a copper content of 56% to 68% has a melting point ranging from 934 to 967 degrees Celsius. Brass boasts good mechanical properties and wear resistance, making it suitable for manufacturing precision instruments, ship components, and more.Different zinc content results in varying colors; for instance, 18%-20% zinc content yields a reddish-yellow hue, while 20%-30% zinc content produces a brownish-yellow shade. Additionally, brass produces a unique sound when struck, which is why Eastern instruments such as gongs, cymbals, bells, and horns, as well as Western brass instruments, are made from brass.Brass is an alloy of copper and zinc. Simple brass is a binary alloy of copper and zinc, referred to as plain or common brass. Adjusting the zinc content in brass alters its mechanical properties. Higher zinc content increases strength but slightly reduces plasticity. Industrially used brass typically contains no more than 45% zinc, as higher levels induce brittleness and degrade alloy performance. To enhance specific properties, other alloying elements are added to plain brass, resulting in special brass. Common alloying elements include silicon, aluminum, tin, lead, manganese, iron, and nickel. Adding aluminum to brass improves yield strength and corrosion resistance while slightly reducing plasticity. Brass with less than 4% aluminum exhibits good comprehensive properties in processing and casting. Incorporating 1% tin significantly enhances brass's resistance to seawater and marine atmospheric corrosion, earning it the name "naval brass." Tin also improves the machinability of brass. The primary purpose of adding lead to brass is to enhance machinability and wear resistance, with lead having little effect on brass's strength. Manganese brass offers good mechanical properties, thermal stability, and corrosion resistance; adding aluminum to manganese brass further improves its properties, yielding castings with a smooth surface. Brass products can be divided into two categories: cast and pressure-processed. more>

Product Description: Composition: Made from a variety of wild plants through slicing, drying, crushing, and winnowing.Characteristics: Appears as a light yellow, free-flowing powder that forms a highly viscoelastic fluid upon contact with water.Main Properties:Water Solubility: Plant gum is insoluble in any organic solvents such as ethanol, glycerol, or formamide; water is the only solvent for plant gum. Viscosity: Plant gum swells and hydrates upon contact with water to form a high-viscosity sol solution. Its viscosity increases significantly with higher powder concentration. Plant gum solution is a non-Newtonian fluid, with viscosity decreasing as shear rate increases. Salt Tolerance: Due to its non-ionic nature, plant gum solution is generally unaffected by anions or cations and does not experience salting-out. Gel Formation: Hydrated plant gum can cross-link with various chemical reagents such as borax and dichromate to form a non-Newtonian water-based gel with certain viscoelasticity. The viscosity of this gel is tens to hundreds of times higher than that of the gum solution.Main Applications:① Exhibits excellent rheological properties, contributing to wellbore stability and effective drill cuttings transport, significantly improving drilling speed and reducing drill tool wear;② Provides effective plugging for permeable formations such as fractured strata and sandstone layers;③ Forms a protective film on rock samples during coring, resulting in higher core recovery rates;④ This product is purely natural, biodegradable, and environmentally non-polluting.Packaging and Storage: Double-layer packaging with inner plastic and outer woven bags, 25kg/bag.
