1: The hydraulic system oil temperature is too high, there is too little oil in the fuel tank, or the oil pump is damaged, requiring refueling or repair. Reasonably select the working pump and recommend the working pressure according to the instructions.
2: The hydraulic system pressure of the drilling rig is insufficient, and the pressure regulating valve fatigue requires adjusting the limiting nut or replacing the spring. If the base of the pressure regulating valve is damaged or stuck, the pressure regulating valve cover should be removed and simple maintenance should be carried out.
3: After the drilling rig oil pump is started, there is no shortage of oil or flow rate. Firstly, check whether the flow rate in the fuel tank is insufficient or not, add oil to the oil mark fault, check whether the filter is blocked, and check whether the ventilation hole in the fuel tank is blocked, and whether there is air intake at the suction pipe joint.
4: Coupled heating of the league, excessive wear of the elastic ring; The reason is that the coaxiality of the power transmission and clutch assembly is not good, and it is necessary to improve the assembly coaxiality.
5: The main reason for the sliding of the drilling rig elevator is oil stains inside the brake band, and it is necessary to clean the inner surface of the brake. If there are no oil stains inside the drilling rig, check the brake band and brake clearance. For example, if it is too loose, it needs to be tightened appropriately.
6: The heating and wear of the drilling rig oil pump must be repaired and replaced. Due to the high or low viscosity of the oil, the oil must be used strictly according to the instructions. Simultaneously inspect the transmission device of the drilling engine oil pump to improve assembly accuracy.
7: The main reason for the slipping of the drilling clutch is due to excessive wear, rupture, or aging or damage of the compression spring on the friction plate. Therefore, it is necessary to inspect the drilling friction plate
