Single rope hydraulic winch SD2215 ton hydraulic winch pull wood
Single-rope hydraulic winch SD2215 ton hydraulic winch pulls the wood hydraulically. In the hydraulic system working process, the liquid flowing in the pipeline often stops suddenly due to the actuator reversing valve or valve closing. Due to the inertia of the liquid flow and the moving elements, a large instantaneous pressure peak is generated in the system. This phenomenon is called hydraulic shock. Hydraulic shock can cause vibration and noise. Its pressure peak can exceed several times the working pressure, and sometimes some hydraulic components, such as pressure relays, sequence valves, etc. will cause erroneous actions to affect the normal operation of the system, and may even cause damage to certain hydraulic components, sealing devices and pipelines. Therefore, the cause of the hydraulic shock should be found out, and the pressure peak can be estimated in order to find the measures to prevent and reduce the hydraulic shock. ...

4 ton hydraulic winch for marine winch
Hydraulic winches for marine winches for ships 4 ton hydraulic winches and improvements to hydraulic winches (1) Improved hydraulic system design. After several demonstrations, the advanced priority valve and load-sensing full-hydraulic steering gear were finally adopted. The new system can give priority to the flow according to the steering requirements. Regardless of the load and the speed of the steering wheel, it can ensure sufficient fuel supply. It can be fully used for the working device circuit, thereby eliminating power loss caused by excessive oil supply to the steering circuit, improving system efficiency, and reducing the working pressure of the hydraulic pump. (2) Optimize the design of boom cylinder and hydraulic pump to reduce the working pressure of the system. Through optimized calculation, the boom cylinder adopts standard series 80/4. liquid...

D46-30X10 horizontal wear-resistant multistage centrifugal pump
Horizontal wear-resistant multi-stage centrifugal pumps Introduction of wear-resistant multi-stage centrifugal pumps are energy-saving, wear-resistant and reliable, and have a long service life. They are particularly suitable for mine drainage. For mine water and other similar liquids, the liquid temperature is not higher than 80 ° C. Variable losses vary with load and include stator resistance losses (copper losses), rotor resistance losses, and brush resistance losses. Fixed losses are independent of load, including core losses and mechanical losses. The iron loss is composed of hysteresis loss and eddy current loss, which is proportional to the square of the voltage, and the hysteresis loss is also inversely proportional to the frequency. Other stray losses are mechanical and other losses, including frictional losses in bearings and wind resistance losses due to rotation, such as fans, rotors ...
