What needs to be done before the diesel generator set is relocated
The use of diesel generator sets to change the use of the unit is mandatory to move the unit, in order to successfully control the user's diesel generator set removal employment, complete the move to another place may wish to pour normal use, which is also the employment focus of the unit's employment. Engine manufacturers share the things that they need to pay attention to during the relocation of the unit, and we hope to send them to the user to help in the employment of diesel generators.
1: Before moving the diesel generator set, the user should first get to know all the conditions of the diesel generator set being moved, and communicate with the original diesel generator manufacturer, if necessary, with the brand, weight, size and parameters of the generator set. Unit materials are checked and records are made when necessary.
2: Before the removal of the moving unit, do a good job in dismantling the power leakage cable. It is necessary to have employees with relevant leakage knowledge skills to join, or to have employees familiar with the operation of this unit to join to ensure the safety of the moving unit and the diesel generator set. Safe from unnecessary destructive disassembly.
3: Moving and relocating Volvo diesel generator sets must find a dedicated moving company to join, and get acquainted with the main parameters such as the diesel generator component amount and size before implementing the moving employment. Guarantee the successful implementation of the moving employment, so as not to destroy the unit during the move. .
4: Don't dominate construction when moving. The key departments of diesel generator sets are joined and disassembled by skilled employees, so as to avoid damage to the unit's installed components, which may cause the unit to malfunction or fail to start employment. All disassembled unit components must be well kept and employed. Dropped or destroyed.
5: The diesel generator set moving to a new place is mandatory to have a dedicated staff to join. The strict example is to implement the assembly of the diesel generator set again. The assembly premise complies with the necessary prerequisites for the use of the diesel generator set. Once the diesel generator set is commissioned, the unit can be used again after passing the commissioning test to ensure the safe operation of the unit.
- 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 part 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.
- 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 it 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
- 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
