Plastic machinery injection molding machine hydraulic fragment in the use of what to pay attention to?

1 The use of people should be clear about the principle of plastic machinery equipment plastic machine hydraulic transmission system, to understand a variety of actual operation and adjustment of the handle parts and rotation, etc.



2 before driving to check the system software adjustment handle, the spindle is not moved by irrelevant staff, electrical switch and limit switch parts are not all normal, the installation of special tools on the server is not appropriate and sturdy, etc., and then the slide rail and hydraulic cylinder to carry out part of the exposed scrubbing, and then can drive.

3 driving, the first to start the hydraulic pump of the manipulation oil circuit, no special type of manipulation oil circuit hydraulic pump, can immediately start the main hydraulic pump.

4 gear oil to be regularly maintained and removed, for the new delivery of hydraulic machinery, the application of 3 months up to and down that should clean the car tank, remove and replace the new oil. After that, every six months to one year to carry out cleaning and oil change once.

5 work should always pay attention to the hydraulic oil, all normal work, the car oil tank in the hydraulic oil temperature should not exceed 60 ℃. The water temperature is too high should find ways to cool, and apply the gear oil with higher viscosity. When the temperature is too low, heating should be carried out, or intermittent operation before running, so that the water temperature gradually rises, and then into the announced work in the operation situation.

6 Check the oil level, to ensure that there is sufficient remaining oil.

7 The system software with gas-water separator should carry out the exhaust pipe, and the system software without gas-water separator should run reciprocally several times to make it certainly discharge the vapor.

8 The car oil tank should be covered with hermeticity, and the air filter should be set at the vent on the top side of the car oil tank to avoid the invasion of waste and water. The oil should be carried out when given oil to make the hydraulic oil clean.

9 The system software should be equipped with coarse and fine filtering devices according to the necessity, and the filtering device should be checked, cleaned removed, and replaced frequently.

10 adjustment of the pressure hydraulic control system, generally the first to adjust the system software pressure regulator ---- regulator valve, from the pressure to zero when the opening adjustment, significantly improve the pressure to achieve the required pressure value; then adjust the pressure regulator of each control circuit. 

The main oil circuit hydraulic pump security regulator valve adjustment pressure is generally more than the implementation of the components required to work in the pressure of 10% - 25%. Rapid fitness movement hydraulic pump pressure valve, the adjustment pressure is generally more than the required pressure 10% -20%. 

If the unloading pressure is used to provide the manipulation oil circuit and the wetting oil circuit, the pressure should be maintained in the range of 0.3 - 0.5 MPa. The adjustment pressure of the pressure car relay should generally be less than 0.3 - 0.5 CPA of the supplied oil pressure.

11 Flow rate adjustment valve should be adjusted from small total flow rate to large flow rate, and it should be adjusted gradually. 

The flow regulating valve of the same fitness exercise implementation components should be adjusted separately to ensure the stability of the fitness exercise.
