Maintenance skills of diesel generator oil pump
As a convenient power generation equipment, diesel generator sets provide great convenience for people in daily production. We should also pay attention to maintenance of daily production equipment, including diesel generator sets. The oil pump is a very important part. The entire oil is Important, so maintenance of the oil pump is a top priority.
The manual pump on the oil pump has a rubber seal between the piston and the hand pump body. Do not disassemble randomly, the rubber ring should be replaced in time. Make sure that the sealing gaskets of all parts of the generator set are intact, and the number of systems should not be too much. They should be replaced regularly. The coarse filter in the joint of the oil pump is easily blocked by viscous substances such as cotton wool. It must be inspected and cleaned regularly. The damage to the filter must be repaired or replaced in time.
Make sure the "four springs" of the plunger pump are normal. Four springs "as piston spring, tappet (roller) spring, suction valve spring, valve spring, spring elasticity weakens or breaks. Replace or add gaskets to adjust in time to avoid damage to the unit.
Time group leader When the generator is off, prevent the matching surface of the oil pump, especially the piston and the pump body, water corrodes the oil tappet and tappet sleeves. Measures must be taken to prevent rust, that is, when the generator stops, replace the fuel injection pump oil bottom Shell with water lubricating oil, diesel and other impurities. After the pump is used, the power pump must be pushed back and the buttons must be tightened to prevent the oil pump and rubber ring or ball valve and valve seat from entering the air or leaking oil due to inadequate pressure.
- The diesel engine is working normally, but the generator fails to generate electricity or the voltage is very low. This may be due to the components associated with the generator, such as: the exciter is damaged, and the excitation voltage cannot be supplied. The excitation current is taken in. The rotor's dead center residual magnetism is weakened or declining. It will make the generator unable to generate electricity or the transmission voltage is extremely low. The right to respond is usually: use an appropriate DC voltage and directly connect to the excitation winding according to the polarity Magnetization. Carefully inspect the exciter and the cyclotron rectifier, find abnormal components or windings, and replace them for restoration. The generator's transmission voltage is unstable, and
- In the power generation industry in China, we have been working hard, pursuing the concept of quality and service, and for the sake of customers, the full power generator chooses China and your generator is a professional housekeeper. At present, the diesel generator set maintenance market refers to damage inspection and routine maintenance. Two aspects: after maintenance refers to the failure of the diesel generator, there are problems with various accessories, such as replacing the generator or
- Before starting, you should check whether the fuel volume of the fuel tank is rich, and there is no oil leakage in each oil pipe and the discussion area; whether the cooling system water is rich, clean and leak-free, and whether the fan belt is tight or not. The internal combustion engine and generator drive parts should be connected and trusted. The wires of the input line are well-insulated, complete and effective in all aspects. After starting, it should run at low speed for 3 to 5 minutes. After the temperature and oil pressure wheel are normal, the initial work can be done. The generator should be no different in the speed increase. Ring, the slip ring and commutator are well brushed, no jumping and sparking phenomenon. After the operation is stable and the frequency and voltage reach the rated value, power can be supplied to the outside.
- Blue smoke, fire reason: It means that the engine is burning oil. There are three types of reasons: first, the piston ring goes opposite, and the oil comes in the cylinder; the second is the oil level of the oil pan of the atmosphere filter, which leads the ring. The height of the groove; Third, the gap between the duct and the valve stem is too poor. Expulsion idea: Adjust the piston ring so that the opening teeth of the ring are staggered 120 degrees or 180 degrees, and the opening teeth of the ring should avoid the piston pin hole and the side pressure is poor. Adjust the height of the oil level of the oil filter of the atmosphere filter below the height of the annular groove; if the clearance between the duct and the valve stem is too poor, replace the component and reduce the clearance. The normal mutual assistance clearance between the two is 0.0
