1. Before starting the oil pump, check carefully the inlet and outlet ports, and if the direction of rotation is consistent with the direction indicated by the sign or not. Don’t reverse rotation.
2. The flexible coupling joint should be used between the pump drive shaft and the prime mover output shaft, and the different axial degrees are not more than 0.1mm.
3. The pump shaft should be protected from radial forces, axial forces and bending moments. When installing the gear pump, the shaft should be introduced slowly. Do not force the impact or axially collide, otherwise the pump will be seriously damaged.
4. The pump's oil absorption height is not more than 0.5m.
5. It is forbidden strictly to bump the connection flange of the oil inlet. The joint surface and joint must be tightly sealed to prevent air leakage, otherwise it will cause abnormal phenomena such as noise, vibration and foam, and reduce the life of the gear pump.
6. The nominal diameter of gear pump suction pipe should ensure the flow rate of oil to be less than 1.5m/s.
1. When installing the motor, the shaft should be imported slowly. Do not force it in.
2. The flexible coupling joint should be used between the motor drive shaft and the power output shaft, and the different axial degrees are not more than 0.1mm.
3. The back pressure of the motor drain port shall not exceed 0.4 MPa.
4. Before installing motor, should check the oil inlet and outlet carefully. Don't reverse rotation and keep the direction of rotation be consistent with the direction indicated by the sign.
1. The joint surface of the valve oil port is strictly prohibited to bump, so that the joint surface and joint are strictly sealed.
2. When installing the external control mechanism, should ensure that the slide valve do not bear the lateral force, so that the slide valve is flexible and has no stuck phenomenon.
3. Install the oil ports correctly and dirt is strictly prohibited.
4. The rated pressure of the safety valve of the hydraulic valve sold by the company has been set before delivery, and it is strictly forbidden to set it at will.
1. When the hydraulic cylinder is in the initial movement, the air should be tried to exhaust in the cylinder to avoid crawling and abnormal noise.
2. To avoid scratch, knock piston rod, so as not to seal failure, oil leakage.
3. While installing, pay attention to adjust the piston rod and the cylinder tube be coaxial to avoid the lateral force of the piston rod, causing the piston rod to bend, pull the cylinder, etc.
4. Check the hydraulic oil before using cylinder and don't use. It is strictly forbidden to use harmful or contaminated oil.
5. Check the system pressure before using. Do not use the cylinder with overpressure.
1. It is recommended to use L-HM46 or similar viscosity hydraulic oil in the summer and L-HM32 or similar viscosity hydraulic oil in the winter.
2. Working oil temperature range -20 ° C ~ 80 ° C.
3. The cleanliness of the system directly affects the reliability of the hydraulic components. Before refueling, the fuel tank and pipeline should be fully cleaned. The oil filter with a filtration accuracy of 100 mesh is generally used on the suction side of the pump (Its rated flow should not be less than two times the pump flow). The oil return line is connected to an oil filter with a filtration accuracy of not less than 25μm.
