The daily maintenance of the engine water pump is very important, and the correct maintenance method can greatly extend the service life of the equipment. Let's take a look at the places to be aware of when using and maintaining engine pumps: 1. When properly installed and installed, the gear of the gear-driven water pump should be tightly integrated with the transmission gear. The belt-driven water pump should ensure that the coaxiality of the pump shaft and the pulley is within the specified range to prevent the engine from increasing the speed or load. Shaking and increasing wear. 2. Correctly adjust the tightness of the belt. The fan belt can't be adjusted too tightly, otherwise it will increase the load of the pump bearing. If it is more than two belt drives, it is necessary to ensure that the old and new, long and short tightness of several belts are consistent, and the uneven tension of the belts is prevented, so that the pump is unbalanced and prematurely damaged. 3. Fill the lubricating oil in time according to the provisions in the manual, and timely fill the water pump bearing with lubricating oil. The amount of lubricating oil should not be too much or too little to prevent premature bearing damage. 4. Do not block the overflow hole. There are overflow holes in the water pump shaft. The overflow hole can be used to observe whether the water pump leaks. If the overflow hole is blocked, the water leaked from the pump will enter the bearing and affect the lubrication, causing premature bearing damage. 5. When disassembling and disassembling, do not slam the hard-washing and repairing the water pump, and disassemble the main components such as the pulley and the pump inner bearing to apply special tools. If the hammer is hard to knock during installation, the pump bearing will be bent and deformed, and the shaft end of the pump shaft will be slipped or damaged. In addition, because the impeller and the pump shaft are tightly fitted, they are generally not disassembled unless necessary. 6. Timely clearing the scale in the water pump. Excessive accumulation of scale in the water pump will weaken the water pumping capacity of the pump, and the scale will also corrode all the components in the pump, which will cause the pump to be damaged prematurely.
