Hydraulic valve installation and use matters needing attention

1. Working Medium 1. It is recommended to use L-HM46 or similar viscosity hydraulic oil in summer and L-HM32 or similar viscosity hydraulic oil in winter.

2, the working oil temperature range -20 °C -80 °C.

3, system cleanliness directly affects the reliability of hydraulic components, fuel tanks, pipelines should be fully cleaned before refueling, general pump suction side of the filter with a precision of 100 mesh filter (its rated flow rate should not be less than twice the pump flow) The oil return pipeline is connected to an oil filter with an accuracy of not less than 25 μm.

Second, the gear pump 1, the pump should be carefully checked before entering the oil inlet, the direction of rotation is consistent with the sign indicating direction, do not reverse rotation.

2. The flexible shaft coupling should be used between the pump transmission shaft and the output shaft of the prime mover, and its different shaft degrees should not exceed 0.1mm.

3, should ensure that the pump shaft does not bear radial force, axial force and bending moment. When installing the gear pump, the shaft should be slowly cut in, do not forcibly hit, axial collision, otherwise it will cause serious damage to the pump.

4, pump suction height is not greater than 0.5m

5. Do not bump the oil inlet flange. Joints and joints must be tightly sealed to prevent air leakage. Otherwise, noise, vibration, foam, etc., abnormal phenomena can be caused, and the life of the gear pump can be reduced.

6. The diameter of the gear pump suction pipe should ensure that the oil flow rate is less than 1.5m/s.

Third, the gear motor 1, the installation of the motor, the shaft should be slowly imported, do not force knock.

2. The flexible shaft coupling should be used between the motor drive shaft and the power output shaft, and the different shaft degrees should not exceed 0.1mm.

3, the back pressure of the motor drain port should not exceed 0.4MPa.

4. Check the inlet and outlet ports carefully before installing the motor. Do not rotate it in reverse. The direction of rotation of the motor should be consistent with the direction indicated by the nameplate.

Fourth, the hydraulic valve
1, valve port joint surface is strictly prohibited bump, ensure that the joint surface, joint tightly sealed.

2. When installing the external operating mechanism, it is ensured that the slide valve does not bear the lateral force, so that the slide valve can move flexibly without any stagnation.

3, the correct installation of the oil port, prohibited the entry of dirt.

4. The rated pressure of the safety valve in the hydraulic valve sold by the company has been adjusted before delivery and is arbitrarily set.
