Company: 云奕超声（深圳）有限公司

Product Description: Industrial ultrasonic cleaners are highly efficient cleaning devices widely used in industrial, scientific research, and other fields. Their working principle involves the cavitation effect generated by high-frequency sound waves in a liquid to clean the surface of objects. An ultrasonic generator produces high-frequency electrical signals, which are converted into mechanical vibration energy through a transducer. These vibrations are transmitted through the cleaning liquid, forming tiny bubbles. When the bubbles collapse, the resulting impact force strips contaminants from the object's surface.The three-tank ultrasonic cleaner features a design with filtration, rinsing, and drying functions, and can also be customized to meet other requirements.Applications of Industrial Ultrasonic CleanersAutomotive parts cleaning: Removes oil stains, dirt, and other contaminants from automotive components, improving cleanliness and extending service life.Optical lens cleaning: Eliminates fingerprints, dust, and other fine particles from lenses to ensure optical performance.Metal stamping parts cleaning: Removes oil stains, rust, and residues from metal stampings, preparing them for subsequent processing or assembly.Electronics industry cleaning: Removes flux residues, dust, and other contaminants from electronic components to ensure device performance and reliability.Aviation industry cleaning: Cleans aviation components, such as engine parts and aviation instruments, ensuring precision and safety.Mechanical and hardware cleaning: Removes cutting fluids, oil stains, and other pollutants from mechanical parts.Watch and jewelry cleaning: Delicately cleans watch components and jewelry, removing dirt from hard-to-reach areas.Silicon wafer cleaning: Removes fine particles and organic contaminants from silicon wafers during semiconductor manufacturing.Mold cleaning: Cleans residual materials from molds, extending their service life and ensuring product quality.Spinneret filter element cleaning: Cleans blockages from filtration equipment to restore filtration efficiency.Materials Used in Single-Tank Ultrasonic CleanersStandard configurations primarily use 304/T2.0 stainless steel for the inner tank and 201/T1.0 stainless steel for the outer shell. If the cleaning agent is corrosive, customers should consult with sales before placing an order to switch to more corrosion-resistant 316 stainless steel.After-Sales ServiceOne-year warranty from the date of shipment, with lifelong maintenance support. more>

Product Description: Non-Shrink Self-Compacting Polymer Concrete is a non-shrink, high-strength, vibration-free concrete developed as a cost-effective alternative to conventional grouting materials. Its performance is essentially consistent with grouting materials, capable of self-compacting formation, and exhibits no shrinkage during the hardening process, with excellent bonding to old concrete interfaces.I. Product FeaturesHigh cohesiveness ensures no segregation during concrete flow and placement;High water retention ensures no surface bleeding during the hardening process;High fluidity ensures self-leveling and compact formation;High strength (maximum strength up to 80MPa), high frost resistance, and high impermeability;No shrinkage during hardening, with micro-expansion properties;High bonding strength with old concrete;Excellent anti-corrosion resistance against chloride ion erosion;Strong resistance to vibration interference during setting and hardening, allowing construction without traffic interruption in projects like highway and railway bridge reinforcement.II.

Application Scope◇ Concrete projects with dense reinforcement, complex shapes, or不便振捣 (inconvenient vibration);◇ Concrete project renovation and reinforcement; ◇ Projects requiring high bonding strength between new and old concrete interfaces;◇ Frost-resistant, impermeable, and corrosion-resistant concrete;◇ Waterproof concrete, steel tube concrete, and shrinkage-compensating concrete (pumped) construction;◇ Large-area concrete floor self-leveling construction.IV. Construction MethodsThe construction and pouring of non-shrink self-leveling compact concrete for beams and columns present high technical difficulties, representing the core and most substantial part of the reinforcement project. Three major challenges must be addressed:①、Ensuring it "flows" without vibration and without bleeding;②、Ensuring newly poured concrete "bonds" effectively with existing old concrete without interface treatment, preventing new interface formation and guaranteeing协同工作 (collaborative work) between old and new concrete;③、Achieving "high strength" while meeting the "flowability" requirement.To achieve these goals, ordinary concrete must be modified into non-shrink self-leveling compact concrete. Our company has mature technology in pouring self-leveling compact concrete, effectively resolving the above issues. more>

Product Description: The KZB-PC motor monitoring device is configured with four monitoring points per motorTemperature Monitoring Point Configuration1. Front Bearing Temperature Monitoring PointInstalled at the motor drive-end bearing to monitor the operating temperature of the drive-end bearing. This is the core rotating component of the motor, where temperature significantly rises during bearing wear or insufficient lubrication.2. Rear Bearing Temperature Monitoring PointInstalled at the motor non-drive-end bearing to monitor temperature variations. This area is highly affected by load, and temperature abnormalities may indicate installation misalignment or uneven load distribution.Vibration Monitoring Point Configuration1. Horizontal Vibration Monitoring PointMounted horizontally on the motor bearing housing (e.g., motor casing or base) to detect vibration amplitude in the horizontal direction. Abnormal horizontal vibration is typically associated with bearing wear, shaft imbalance, or misalignment.2. Vertical Vibration Monitoring PointInstalled vertically on the bearing housing (e.g., motor top or flange) to monitor vertical vibration. Abnormal vertical vibration may indicate internal bearing faults or foundation loosening. more>

Product Description: 树枝粉碎机是用于将树干或树枝粉碎成木屑的一种机械设备，其主体部分由装在同一轴上的盘和多组锤片组成。粉碎机上有两个进料口，一个靠近盘侧，是树干的进口；另一个在锤片组的前方，是树枝的进料口。因为树枝较细，可不经盘削片直接送入锤片区打碎。目前，市场上的树枝粉碎机大多只是在锤片区前方设置一个简单的进料口；在依靠人工投入树枝、尤其是枝桠杈时，由于缺乏继续进给的动力，经常出现树枝难以顺利送入的现象，进料速度慢，严重影响树枝粉碎的生产效率。另外，也有部分树枝粉碎机虽然设置了液压驱动的进料辅助装置，但因为这类液压装置需要装备相应的液压传动系统（包括油泵、油箱、液压缸等），所以导致整个进料辅助装置的结构过于复杂、体积庞大，制造成本高，不利于装置的使用推广。故有必要对现有技术的树枝粉碎机进料辅助装置予以改进。 more>
