Diesel generators pump maintenance method 1, check the pump and pulleys for wear and damage, replace if necessary. Check whether the pump shaft is bent, the journal wear, shaft thread damage. Check the impeller vanes on the presence or absence of broken shaft bore wear is serious. Check the gasket seal and wear bakelite, such as exceeding the usage limit should be replaced with new parts. Check bearing wear, available tables measure the bearing clearance Cummins generator rental, if more than 0.10mm, it should be replaced with new bearings. 2. Check whether the pump bearings rotating flexible or abnormal sound, if there is a problem description bearings should be replaced. 3. After removing the pump, where the generator rental, according to the order of decomposition. After decomposing parts should be cleaned, and then one by one to check to see if there are cracks, damage and wear and other defects, should be replaced if there are serious flaws. 4, with the following damage on the pump to allow welding repair: length less than 30mm, the crack does not extend to the bearing bore; flange engages with the cylinder head has a breaking section; seal housing bore damage. Bent pump shaft shall not exceed 0.05mm, or should be replaced. Impeller blades damaged should be replaced. Pump shaft aperture badly worn should be replaced or repaired casement. 5, seal and seat repair: seal, such as wear and tear from the slots available emery cloth polished, such as wear off even should be replaced; seal seat if rough scratches, can flat reamer or a lathe repair. Replacement of the seal assembly should be overhauled. 6, pumps assembled, hand turn about, the shaft should be no catching, impeller and pump housing should be no grazing. Then check the pump displacement, if the problem of high-power generator rental, you should check the reason and excluded. If the pump fails, coolant will not reach the appropriate place, and its performance is the lack of effective play, and ultimately affect the work. Therefore generator rental, we must strengthen the inspection of the pump. In order to reduce wear and tear generator equipment, pump repair work must be done, this is the most important service. In order to best support Cummins users and agents in China, in order to help you quickly determine the real cause of the failure encountered in use and the ability to properly troubleshoot, we are here to determine the fault list generator and Dongguan The basic principles and basic maintenance steps, while the series are listed Cummins engine fault diagnosis and repair process briefly. Fault diagnosis and repair of basic principles are: Think before you do, from simple to complex, from outside to inside, the eradication failure. Fault diagnosis and repair of the basic steps are: ◆ collect all users complain about the real situation ◆ ◆ thorough analysis clearly the fault of the fault symptoms and basic engine systems and components linked ◆ A recent analysis of any possible behavior and complaints related to the maintenance and repair ◆ At the beginning of any demolition work need to be checked again before ◆ use troubleshooting process begins with a brief easiest thing to do to solve the problem ◆ determine the cause of the fault, and thoroughly repair ◆ After completing the repair, operation of the engine, to ensure that the reasons have been complaining corrected. Fault diagnosis and repair process can help you start with a brief easiest and most logical place to start, according to the order from top to bottom, by the steps to find and solve problems. But the process can not be all of the solution brief, including the problem; however, it can inspire ideas, the stream on the diesel generator maintenance electromechanical guide you find the cause of the failure and be excluded.
