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 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, 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 generator rental price, the coolant will not reach the place where the corresponding generator rental, 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. EVN has made great progress in the development of more "investment" reported that, in recent years, Vietnam has made great progress in power development. First, the large increase in electricity consumption. 2014 total generating capacity of 8.6 times in 2000, an average annual increase of 12.9% in the first nine months of 2013 the country's total electricity consumption in Vietnam is 92.2 billion kwh, the total annual electricity consumption is expected to exceed 123 billion kwh. Second, the large structural changes electrical energy. 2012, Vietnam accounted for 39.4% of natural gas power generation, hydropower accounted for 38.8%, 21.4% coal power generation, oil and electricity generation accounted for 0.4%. Third, power increase over the large increase in population. Vietnam in 2012 annual per capita consumption in 2000 was 3.8 times the average annual increase of 11.7%. Fourth, Vietnamese enterprises to participate in various types of power production, power management and continuous improvement of transportation in rural areas, to ensure safe use of electricity. However, there is still insufficient power development in Vietnam. Energy, solar power development is slow; coal mining face difficulties in the future is likely to be imported. A larger proportion of hydropower, cheap trailer generator rental, but the negative impact of large, such as environmental pollution, agriculture and forestry production. Due to the low starting point, Vietnam electricity supply failed to meet the needs of social development, still has to import large amounts of electricity annually.
