Lubrication: all moving parts shall be regularly coated with high-quality molybdenum disulfide or corresponding grease. Under mixed environment, cleaning and lubrication shall be carried out frequently.
Hydraulic oil pipe: check whether the oil pipe is broken or leaking after each operation, and clean the dirty joint regularly.
Quick connector: the connector shall be kept clean and shall not be dragged along the ground. Small dust may cause failure of internal check valve. Seal with high quality sealing material. Straight plug quick fitting, safe, fast and reliable.
Spring: the spring installed between the driving pawl and the reaction pawl. If it has the ability, it is better to check and replace it once every two years.
Cylinder seal: if any leakage is found, it is recommended to replace the sealing ring and the deformed components.
Structural parts: the structural parts of tools shall be inspected once a year to determine whether there is any fracture, defect or deformation. If there are any, they shall be replaced immediately.
Rotary joint of DH and HH power heads: check the rotary joint regularly, if leakage is found, replace the seal; if cracks are found on the joint body, replace the rotary joint immediately.
Cleaning: soak the hydraulic components with non corrosive cleaning fluid, and wipe them with hydraulic oil after cleaning.
Hydraulic pumping station
Hydraulic oil: the hydraulic oil shall be completely replaced after 40 hours of continuous operation or once a year to ensure that the tank is full of hydraulic oil at all times.
Quick joint: the joint shall be inspected regularly to prevent leakage. The joint shall be free from dirt and foreign matters. It shall be cleaned before use.
Pressure gauge: the pressure gauge is a wet type filled with liquid. If the liquid level drops, it indicates that the pressure gauge is leaking. If there is hydraulic oil in the gauge, it indicates that the pressure gauge has internal failure and needs to be replaced in time.
Filter screen at the oil inlet of the pump station: in normal use, the filter screen should be replaced once every two years. If it is frequently used, it should be replaced frequently.
Motor (pneumatic and electric): the motor shaft and bearing shall be cleaned and lubricated once a year.
Remote control switch (pneumatic): the air pipe connecting the remote control switch shall be checked regularly to prevent blocking or binding. If the air pipe is bent or broken, it needs to be replaced. The spring load button on the remote control handle needs to be checked in case of difficult operation.
Air valve (pneumatic): the valve should be checked twice a year.
Electric drive, rotor (electric): annual inspection.
Pump set: when the oil tank temperature of the pump set is too high (about 70 ℃), the pump set shall be shut down for cooling before operation. The pump unit shall be carefully inspected once every two years, preferably by the manufacturer or qualified hydraulic service center.
