3. Application Scenarios and Advantages
① Application:
Injection molding machine main hydraulic system: provides stable high-pressure oil for plastic injection, pressure holding and other actions.
Die-casting machine injection system: drives the injection mechanism to enable the molten metal to fill the mold at high speed.
Construction machinery hydraulic system: drives hydraulic cylinders to achieve actions such as digging and loading, suitable for medium to large equipment.
② Advantages:
Large flow rate: The dual-connection design can provide a larger flow rate to meet the needs of medium and large equipment.
Pressure stability: optimize flow characteristics, reduce pressure fluctuations, and improve system stability.
Easy installation: Flange installation method is easy to connect to the equipment and saves installation space.
4. Common Problems and Solutions
① Insufficient pressure
Cause: internal wear of hydraulic pump, overflow valve failure, low oil viscosity.
Solution: Check and repair worn parts, adjust or replace overflow valve, and replace oil with appropriate viscosity.
② Excessive noise
Cause: loose installation, non-concentric coupling, clogged oil suction pipe, air in the oil.
Solution: reinstall and fix, adjust the coupling, clean the oil suction pipe, and remove the air.
③ Unstable flow
Cause: Blade wear (for vane pumps), stator curve wear, oil contamination.
Solution: Replace worn blades or stators (for vane pumps), clean or replace the oil.
