The role of the water pump is to increase the cooling water pressure, so that the water in the cooling system to accelerate the cycle, the current diesel generator set is widely used centrifugal water pump, in order to ensure that the cooling system to maintain good working condition, the user in the use and maintenance of diesel generator set water pump must not ignore the following details.
The role of the water pump is to increase the cooling water pressure, so that the water in the cooling system to accelerate the cycle, the current diesel generator set is widely used centrifugal water pump, in order to ensure that the cooling system to maintain a good working condition, the user in the use and maintenance of diesel generator set water pump must not ignore the following details.
1, correct installation. When installed, the gears of the gear-driven water pump should be closely combined with the transmission gears, and the belt-driven water pump should ensure that the coaxiality of the water pump shaft and pulley is within the specified range to prevent the engine from increasing the speed or load and causing the water pump to shake and intensify wear.
2, check the diesel water pump drive coupling plate: check whether the connecting bolt is loose, if there is loose tighten the bolt in advance.
3、Adjust the belt tightness correctly. Fan belt should not be adjusted too tight, otherwise it will increase the load of the pump bearing. If there are more than two belts, make sure that the newness, length and tightness of several belts are the same, so as to prevent uneven tension of each belt and premature damage to the water pump due to unbalanced force.
4、Fill lubricant in time. According to the manual, the pump bearing should be filled with lubricating oil in time, and the quantity of lubricating oil should not be too much or too little to prevent premature damage to the bearing. Do not block the water overflow hole. Some pumps have water overflow holes at the shaft, through the water overflow holes can observe whether the pump leaks. If the overflow hole is blocked, the water leaking from the pump will enter the bearing and affect the lubrication, causing premature damage to the bearing. Do not hit hard when disassembling and assembling. When inspecting the pump, dismantle the main parts such as pulley and bearing in the pump with special tools. If you hit hard when installing, it is easy to cause the pump bearing to bend and deform, and the thread of the pump shaft end to slip or damage. In addition, because the impeller and pump shaft with tighter, unless necessary, generally do not disassemble.
5, timely removal of scale in the pump. Too much scale accumulation in the pump will make the pump pumping ability weaken, and the scale will also corrode the parts in the pump, which will make the pump damaged prematurely.
6, clean the pump and accessories equipment appearance: dry cloth or dipping diesel cloth to wipe the body, cylinder head, air filter and other surface oil, water and dust, with compressed air or fan to blow the generator, radiator, fan surface dust.
Diesel generator pump can be used effectively, relying on the user's usual maintenance and maintenance, the above pump maintenance details hope to be useful to you.
