Maintenance Methods of Silent Diesel Generator Set Water Pump

May. 13, 2022

When installing the water pump of the silent diesel generator set, the gear of the gear-driven water pump should be closely combined with the transmission gear, and the belt-driven water pump should ensure that the coaxiality of the water pump shaft and the pulley is within the specified range to prevent the engine from increasing the speed or load. As a result, the pump shakes and aggravates wear.

Correctly adjust the tightness of the belt of the silent diesel generator set. The fan belt should not be adjusted too tight, otherwise it will increase the load on the water pump bearing. If it is driven by two or more belts, it is necessary to ensure that the old and new, length and tightness of several belts are consistent to prevent premature damage to the pump due to uneven tension of each belt.


Add lubricating oil in time. It is necessary to add lubricating oil to the pump bearing of the silent diesel generator set in time according to the regulations in the manual. The amount of lubricating oil added should not be too much or too little to prevent premature bearing damage. Do not block the overflow hole. 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 from the pump will enter the bearing and affect the lubrication, causing the bearing to be damaged prematurely.


Do not knock violently when disassembling. When overhauling the water pump, use special tools to remove the main components such as the pulley and the bearing in the water pump. If it is hit hard during installation, it is easy to cause bending deformation of the water pump bearing, thread slip or damage to the shaft end of the water pump. In addition, because the impeller and the pump shaft are tightly matched, it is generally not dismantled unless necessary. Remove the scale in the water pump of the silent diesel generator set in time. Excessive accumulation of scale in the water pump will weaken the pumping capacity of the water pump, and at the same time, the scale will corrode various components in the water pump, which may cause the water pump to be damaged prematurely.
