Method for extending the service life of a diesel generator coupling

In addition to the quality problems of diesel generators, improper use of the machines, and maintenance and repairs that are not timely and incorrect will also cause damage to the coupling. Here are some points on how to extend the life of the couplings for reference.

1. Strictly implement the fuel precipitation filtration system. Less diesel fuel should be collected after 48 hours of precipitation. The diesel used should meet the standard model of the season. Refueling tools should be cleaned exclusively. The areas for refueling and storing oil should also be cleaned so that dirt does not mix with the fuel to accelerate the wear of the coupling and reduce the life of the coupling.

2. Strict technical maintenance and maintenance regulations are formulated. The fuel filter works for 100 hours and the fuel tank works for 500 hours each. If it is found that the damage effect of the filter element is replaced in time, it must not be dismantled and a direct-current fuel supply must be used. Couples shall be disassembled and inspected once 500 hours of working under normal working conditions. In the demolition inspection, ensure that the site, hands, tools and cleaning oil are clean to avoid contamination of the coupling parts. During the disassembling operation, it shall not be tapped indiscriminately. When cleaning, do not dispose of it in a random manner. Do not wash it together with other non-partial parts to avoid bruising or scratches. During assembly, it is not allowed to change the assembly position arbitrarily to achieve certain purposes that do not meet the working requirements of the machine. When installing the oil valve tight seat and the oil nozzle tight cap, tighten according to the specified torque to ensure that the assembled fuel injector and fuel injection pump are in good technical condition.

3, in addition to the above requirements, we should also improve the understanding of dual parts, understand the structural characteristics and working principle of the couple, strengthen and improve the maintenance of the dual parts, operation and use, so that when there is no fault, do not arbitrarily adjust, maintenance use Do not arbitrarily dismantle, maintenance and inspection will not be indiscriminately knocking, cleaning and maintenance does not rub indiscriminately, when the assembly adjustment does not change chaos screw, all in accordance with the specification of technical requirements, in order to achieve the purpose of extending its service life.
