To explain to you about the emulsion pump technology machine maintenance
The emulsion pump is operated by a full-time driver who has received formal training. Managers above the electromechanical squad leader need to carefully check whether the oil level of each part meets the requirements before supervising and managing and starting the emulsion pump. For example, the oil level in the pump shell must be between the upper and lower limits of the cursor glass after the pump works. Before the middle position works normally, it is necessary to check whether all mechanical parts, connecting parts, lock nuts, U-shaped cards, etc. are damaged and loose, and whether there is leakage in all pipelines. Before turning on the power supply, turn on the power supply, make the pipette chamber empty, press the operation button according to the operation sequence, observe the rotation direction of the motor, and start it officially after confirmation. After starting the emulsion pump, pay attention to releasing the air in the high-pressure chamber to make the emulsion pump work for 10min without load, after a comprehensive inspection of the pump body, oil tank, hydraulic piping, etc. for abnormalities, in the process of applying pressure with the emulsion pump, contact the oil tank regularly, and the oil temperature is below 80.
Daily maintenance of emulsion pump
In daily work, when the emulsion pump fails, the fault judgment should be made first. The method is to visually observe the indication status of various instruments, the connection status of each connecting part, the movement coordination of each rotating part, the damage status of each hydraulic piping part, the condition of lubricating oil and working oil level, and various mechanical damages, etc, observe whether the working sound of the emulsion pump is normal, and whether the rotation of each rotating part is correctly affected by abnormal impact and gunfire.
The above methods are used to investigate and judge the fault source and cause one by one. The fault treatment steps are to check the suction valve, air release valve, spring and seal ring, check the plunger and cavity for mechanical damage, check the lubrication condition, check the oil leakage, loose firmware, damaged parts, mixed foreign matter, poor lubrication and poor lubrication. In addition, regarding spare parts such as unloading valve assembly, cylinder assembly and pressure reducing valve assembly, please try to assemble, check and replace in case of failure to prevent action failure caused by assembly or coordination.
Emulsion pump is the core equipment of the hydraulic system of the whole coal mining face. Its working efficiency and service life are directly determined by daily maintenance and maintenance. When a fault occurs, fast and accurate fault judgment, analysis and treatment are very important to ensure the safe and efficient production of coal mines. Therefore, it is necessary to analyze and be familiar with the common faults of emulsion pumps in working faces for front-line technicians, mechanical and electrical maintenance personnel, emulsion pump workers and other related staff, master the correct treatment method, correctly judge the various faults encountered in the process of work, quickly eliminate, and ensure the high yield and high efficiency of coal mine.
