Use method and characteristics of oil pump

发表时间:2017-12-01 Article source : Couch motor manufacturersPublished time: 2017-12-01

A small oil pump is an important part of the diesel generator set. The small oil pump industry pays attention to it. In order to maintain the reliability of the diesel generator set, the diesel generator set is installing an oil transfer pump to check whether it is correct and standardized, and to eliminate rust. The thickness of the blade should be appropriate.In order to prevent the piston from being dead or running in place, the gasket should be prevented from being too thick or thin.The tightening torque of the tightening bolt should be uniform to prevent damage to the pump.
The rubber sealing device between the hand pump piston and the oil pump hand pump body should not be dismantled, and the rubber ring should be replaced in time. The primary filter at the outlet of the oil pump is easy to be blocked. Due to cotton wool and other viscous materials, it must be inspected and cleaned frequently. .
Make sure that the gasket of the diesel generator set is intact, and the number of machines is not large, and it should be replaced regularly. Make sure that the "four springs" of the plunger pump are normal. The four "springs" are piston springs, springs, inlet valve springs, oil valve springs, and spring elasticity. Weaken or break, replace or buffer in time to avoid damage to the diesel generator.
After using the oil pump of the diesel generator set, the pressure must be backed up and the buttons must be tightened to prevent the air pump or rubber ring or ball valve or valve seat from causing air intake or oil leakage. When the diesel generator set is stopped for a long time, prevent the matching surface of the oil pump, especially the piston With the pump body and water corrosion oil tappet tappet sleeve, measures must be taken to prevent rust, that is, when the generator is stopped, replace the injection pump oil pan and water lubricating oil, diesel and other impurities.
The diesel generator set oil is filtered through sedimentation to ensure cleanliness, to prevent excessive impurities and fuel delivery pump water valve, oil valve, valve seat wear, oil valve, and sometimes even impurities and malfunction. It is found that the fuel injection pump oil pan oil It is necessary to check the pump body of the pump and the piston pump in time.The gap between the tappet and the tappet is too large and cannot be handled in time to prevent serious oil leakage from the diesel generator set and poor internal lubrication of the fuel injection pump and the governor.
Some diesel generators have drainage holes in the pump body, and the role of the pump is to directly drain a small amount of oil from the pump. It is forbidden to block the holes to prevent oil from entering the pump oil.

    The assembly place needs to be well ventilated, the generator end should have sufficient air inlets, and the diesel engine end should have excellent air outlets. The area of the air outlets should be more than 5 times larger than the area of the water tank. The periphery of the assembly site should still be clean to prevent the formation of surrounding installations. Cargoes with corrosive gases and steam such as acid, alkali, etc. Fire extinguishing devices should be equipped if required. If used indoors, the smoke exhaust pipe must be opened to the outside, the diameter of the smoke pipe must be ≥ the diameter of the smoke pipe, and the pipe connected The elbow failure should exceed 3 to ensure the exhaust smoke circulation, and the pipe should be tilted downward by 5-10 degrees to prevent rainwater intake; if the exhaust pipe is assembled vertically upward, then

    The diesel generator set can be repaired and maintained in the middle of 6000-8000 hours. The overall control text is as follows: Check the wear level of the diesel generator set valve, the valve seat of the diesel generator set, and repair or change the diesel generator set if necessary; Check the occupational status of PT pumps and fuel injectors for leased generators, and repair and adjust if necessary. Check and adjust the torque of connecting rods and fastening screws of diesel generator sets; check and adjust the valve clearances of diesel generator sets; adjust leases The course of the injector of the generator; check the tension of the belt of the mediator fan charger; scrub the intake manifold

    Regarding the generator leasing problem in the use process, what should I do? This anomaly is a bit of concern for many customers who want to rent a generator. Let ’s answer it. At the beginning, as a focused generator set rental supplier The maintenance of the settings and the handling of hidden dangers in advance are real-time, thoughtful, and focused. Maybe the machine is out of the warehouse with a disease. Secondly, no supplier can promise that the settings supplied by me will not be out of order. Even new The settings are also different. For this reason, regarding the unexpected problems in the utilization process, we will send the customer to the promised hour for disposal, if necessary

    In some places far away from the power supply, the only option is to use a diesel generator to ensure the power supply. This small-scale power generation equipment is widely used in remote areas and is of great significance to local residents. But what should I do if the diesel generator fails? What are the specific uses of diesel generators? Let ’s take a closer look at “What are the causes and uses of diesel generator failures?”
