A. Hazards caused by high temperature of hydraulic oil of water well drilling rig:
1. The high temperature of the hydraulic oil of the water well drill makes the machine slow and weak, which seriously affects the working efficiency of the water well drilling rig, and increases the oil consumption of the engine.
2. The high temperature of the hydraulic oil of the water well drilling rig will accelerate the aging of the hydraulic seals, reduce the sealing function, and make it difficult to solve the oil dripping, oil leakage and oil seepage of the machine, which will cause severe machine pollution and economic losses.
3. The high temperature of the hydraulic oil of the water well drilling rig will lead to the increase of the internal discharge of the hydraulic system and the instability of various functions of the hydraulic system. The working precision of the hydraulic system decreases. When the valve body and valve core of the control valve expand due to heat, the cooperation gap becomes smaller, which affects the movement of the valve core, increases the wear, and even causes the valve to jam, seriously affecting the work of the hydraulic system.
4. The high temperature of the hydraulic oil of the water well drilling rig will lead to the decline of the lubrication function and the viscosity of the hydraulic oil. When the temperature rises, the activity of liquid molecules will increase, the cohesion will decrease, the hydraulic oil will become thinner, the oil film of the hydraulic oil will become thinner and easily damaged, the lubrication function will become worse, and the wear of hydraulic components will increase, endangering important hydraulic components such as hydraulic valves, pumps, locks, etc.
B. Solutions for high temperature of hydraulic oil of water well drilling rig:
We should analyze and deal with the hydraulic high temperature problems of the water well drilling rig according to the detection methods from outside to inside, from simple to messy, and from intuitive to microscopic:
1. First, check whether the hydraulic oil radiator is too dirty, hydraulic oil level and oil quality, and check the filter element. If there is any problem, clean and replace it in time;
2. Check whether the hydraulic system of the water well drilling rig leaks oil, and replace the sealing and damaged parts if any;
3. Use a multimeter to check whether the circuit is faulty and the sensor is damaged, and check whether the actual hydraulic oil temperature is too high. The normal hydraulic oil temperature is 35-65 ℃, and it can reach 50-80 ℃ in summer;
4. Check whether there is abnormal noise in the hydraulic pump of the water well drilling rig, whether the oil discharge amount of the oil discharge pipeline is too much, and whether the working pressure is too low. Use a pressure gauge to test the working pressure of the hydraulic system;
5. If the above inspection is normal, check the oil return check valve of the hydraulic system of the water well drilling rig, disassemble it to check whether the tension spring is broken, jammed and other problems appear, and clean or replace it if there are problems;
6. Check the power of the water well drilling rig, such as supercharger, high-pressure pump, injector, etc.
