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, the gap can be used to measure the bearing table, if more than 0.10mm silent generator rental, 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, 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, any questions, 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, 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. Technological development and the level of skill levels of diesel generator sets and diesel engine is closely related to measure and evaluate the performance of diesel generator sets are often used as an important part of the diesel engine. Because everyday use and regular maintenance work, mainly diesel engine power generator rental, and thus excellent performance diesel engine is a solid foundation for modern turbines. Currently, foreign diesel generator diesel engine power greater than 50kW, have widespread use turbocharging technology to improve specific power, while the useful application of different cooling technology, combined with multi-valve technology, the diesel engine than the power further strengthened. Its up to 1.98kg / kW value ratio of the highest quality, and quality than regular diesel engines in 8.0 ~ 20kg / kW, it shows disparities. Due to intensive than the power generator rental, the intake system, fuel supply system, piston assembly, material properties must crank linkage mechanism for continuous improvement and improvement of Cummins generator rental, the level of the production process also put forward higher requirements . The following table is a 2000-2009 China diesel generator set market demand statistics, in 2000 the demand for Chinese diesel generator set is approximately 450,000 units in 2003 due to lack of electricity nationwide, especially the southeast coastal cities, resulting in a diesel generator set market Crazy amplification, the annual demand to reach 126 million units in 2004 declined roughly 98 million units. 2008 snowstorm in the south will also enable the domestic market to 1.13 million units, an increase of 43.04% compared to 2007. Receive the impact of the financial crisis in 2009, many factories have reduced domestic spending and production inputs, the domestic market capacity fell to 640,000 units of the scale. Generator rental company, Shunde generator rental, on firewood provided by the Electrical and Mechanical and Electrical Equipment Co., Dongguan ShangXi firewood. Electrical Equipment Co., Ltd., Dongguan ShangXi Chai (www.dongguanfadianji.cn) strong, credible, diesel generator sets and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the diesel generator and you hand into the brilliant, for a better future!
