        It is not difficult to extend the service life of diesel driven pumps and pumps

        Author: Source: Posted On: 2019/10/11 11:58:34

          The life of a diesel engine depends on how well it is used properly. If it is used in accordance with the skill of use, it will directly increase its life time. The first is to avoid empty pumps. The second operation is to avoid rust and corrosion of the impeller and the seal ring, and damage the seal gap. Third, it is necessary to avoid the horizontal centrifugal pump pumping more than the suction stroke. Do not put the fourth packing too tight, and have enough cooling water to flow out of the shaft.
          The consumable parts of the diesel engine pump include three filters: air filter, oil filter and diesel filter. To extend the service life of the diesel pump, the air filter should be strengthened during use. The maintenance of the three filters of the oil filter and the diesel filter gives full play to their role.
          The air filter should not be installed, reverse-mounted or misplaced with each sealing gasket and rubber connecting pipe during installation, and ensure the tightness of each pressing. Use the paper dust cup air filter. For every 50-100 hours of work, remove the dust once. Use a soft brush to brush off the surface dust. If the working time exceeds 500 hours or it is damaged, it should be replaced in time. Use oil bath air filter, clean the filter element and replace the oil in every 100-200 hours of operation. If the filter element is broken, it needs to be replaced immediately, and pay attention to the addition of oil according to the regulations.
          If the oil filter is not in time for maintenance in the diesel pump unit, the filter element is clogged, the oil pressure is increased, the safety valve is opened, and the lubricating oil directly flows into the main oil passage, which will aggravate the wear of the lubricating surface and affect the service life of the diesel water pump unit. Therefore, the oil filter should be cleaned once every 180-200 hours of operation and found to be damaged. It should be replaced immediately to prevent impurities from entering the lubrication surface.
          The pump unit should be used in seasons. The crankcase and each lubricating surface should also be cleaned. The method is to mix the oil, kerosene and diesel oil for washing oil. After the oil is released, it can be washed with detergent oil. Then, the diesel pump unit runs at low speed for 3-5 minutes. , then drain the washing oil and add new oil.
          For each fuel filter in the fuel supply system, every 100-200 hours of operation, the debris should be removed once, and the fuel tank and each oil pipeline should be thoroughly cleaned. When cleaning the filter element and seal, it should be especially careful to find damage and need to be replaced in time. During the seasonal transition, the parts of the entire fuel supply system should be cleaned. The diesel used should meet the seasonal requirements and require 48 hours of precipitation purification.
