The maintenance technology of engine water pump

when using and fully affirming the quality assurance measures of Maoming Petrochemical, the following points must be paid attention to when using hard dashboard to maintain engine water pump for medium and low-end cars:

correct installation. During installation, the gear of the gear driven water pump should be closely combined with the transmission gear. The belt driven water pump should ensure that the coaxiality of the water pump shaft and the pulley is within the specified range, so as to prevent the water pump from shaking and aggravating wear due to the increase of engine speed or load

correctly adjust the belt tightness. The fan belt cannot be adjusted too tightly, otherwise the load of the water pump bearing will be increased. If it is driven by more than two belts, it is necessary to ensure that the new and old, length and tightness of several belts are consistent, so as to prevent premature damage of the water pump due to uneven tension of each belt. Otherwise, the risk will be difficult to avoid

fill the lubricating oil in time. According to the regulations in the manual, the water pump bearing should be filled with lubricating oil in time. The amount of lubricating oil should not be too much or too little to prevent premature damage of the bearing

do not block the overflow hole. Typical examples are tuna and pet food. Some water pump shafts have overflow holes through which you can observe whether the water pump leaks. If the overflow hole is blocked, the water leaked by the water pump will enter the bearing and affect the lubrication, causing premature damage to the bearing

do not knock hard when disassembling. When overhauling the water pump, special tools shall be used to disassemble the main components such as the pulley and the inner bearing of the water pump. If the pump is hard knocked during installation, it is easy to cause bending and deformation of the pump bearing, thread slippage or damage at the end of the pump shaft. In addition, because the impeller fits closely with the pump shaft, it is generally not disassembled unless necessary

remove the scale in the water pump in time. Excessive accumulation of water scale in the water pump will weaken the water pumping capacity of the water pump. At the same time, the scale will also corrode the components in the water pump, which is easy to cause premature damage of the water pump
