Hydraulic Cylinder Hydraulic joint Hydraulic pumps. Hydraulics,Hydraulic Cylinders, Log Splitters and Components,Hydraulic Motors,Hydraulic Pumps,Hydraulic Valves,Hydraulic Power Units,Hydraulic. Hydraulic press accessories are installed on the hydraulic press, play an auxiliary role, the role of different hydraulic press accessories is also different, such as the oil filter is used to filter impurities in the hydraulic oil, the accumulator is used to store and release pressure, the oil tank is used to store hydraulic oil and so on.

1. Test the motor steering is correct (with the pump body marked on the direction), the test time is short so as not to pump the internal rotation of the wear parts due to dry lubrication without liquid damage; drum pump 2. Open the exhaust valve to fill the liquid The entire pump, to be closed after the exhaust valve;
3. Check the various parts are normal; pneumatic diaphragm pump 4. High-temperature type should be preheated, the heating rate of 50 ℃ / hour, to ensure that all parts of the heat evenly. Colloid mill Second, start:
1. Close the pump outlet valve ;
2. Full open pump inlet valve;
3. Start the motor and observe whether the pump is running normally;
4. Adjust the outlet valve opening to the required conditions, such as users at the pump outlet equipped with flow meter or pressure gauge, the outlet valve should be adjusted by the opening of the pump performance parameters listed in the rated point on the operation, such as users In the pump outlet is not installed flow meter or pressure gauge, the outlet valve should be adjusted by opening; measuring pump motor current, the motor running within the rated current, otherwise it will cause the pump to overload operation (ie, high-current operation, Motor burnout) to adjust the outlet valve open big and small and pipeline conditions;
5. Check the seal leakage, the normal mechanical seal leakage should be less than 3 drops / min;
6. Check the motor, bearing temperature rise ≤ 80 ℃.
Third, downtime:
1. Close the outlet pipe valve
Cut off the power
3. Close the inlet pipe valve; submersible pump 4. If the pump is stopped for a long time, the liquid in the pump should be drained
Pump the correct steps
First, before the start of preparation:
