Baotou beiben heavy truck parts pump is one of the important parts in automotive engine cooling system, the effect of the water pump is the North Pennines heavy truck based on the coolant pressure, ensure the circulation flow in the cooling system, speed up the heat emission. As a means of long-term operation, the use of the process, the pump will be North Pennines heavy truck fault, how to examine and repair the fault, many people will think this examination is very complex, failure of direct repair, in fact, there are some small fault owners can be solved completely, do not need to spend money. “”. The car is in use if the North Pennines heavy truck pump failure or damage, do the following inspection and repair.
1 check the pump body and the belt pulley wear and damage, if necessary, should be replaced. Check the pump shaft with no bending, the degree of shaft neck wear, shaft end thread with no damage. Check the blade on the impeller there is no broken, shaft hole wear is serious. Check the degree of wear of seal and bakelite washer, such as more than the use of limit should be replaced with new parts. Check bearing wear, the available table measurement of the clearance of the bearing, such as more than 0.10mm, you should replace the new bearing.
2 pump North Pennines heavy truck after removing the sequential decomposition. After the decomposition of parts should be cleaned, and then one by one check to see if there are cracks, damage and wear and other defects, such as serious defects should be replaced.
3 in the pump body has the following injury to allow welding repair: length within 3Omm, does not extend to crack the bearing seat hole; a breaking part and a flange joint of the cylinder cover; oil seal seat hole damage. Beiben heavy truck pump shaft shall not be bent over 0.05mm, otherwise it should be replaced. Impeller blade damage should be replaced. Baotou beiben heavy truck parts pump shaft hole worn should be replaced or insert repair.
4 check the North Pennines heavy truck pump bearing rotating flexible or abnormal noise, such as a bearing, should be replaced.
5 repair water seal and seat seal: such as wear groove, available emery cloth grinding, such as too much wear should be replaced; seal seat as coarse scratches, available plane or repair in the lathe reamer. In the overhaul should be replaced with new seal assembly.
6 Baotou beiben heavy truck parts assembled by hand pump, pump shaft rotation, no delay, impeller and pump casing grazing. Then check the pump discharge, if there is a problem, should check the cause and rule out. If the North Pennines heavy truck pump failure, the coolant will arrive at the corresponding place to, its performance is not effectively play, thus affecting the working condition of the engine. Therefore, we must strengthen the North Pennines heavy truck pump check.
