Diesel Generator Tech

When the temperature is low, the diesel generator shall be preheated, otherwise it is difficult to start. For the manually started diesel generator, gradually increase the speed, and then pull the pressure reducing handle to the non pressure reducing position, so that there is normal compression in the cylinder of the diesel generator. If the pressure reducing mechanism of the diesel generator is improperly adjusted or the valve is against the piston, it is often difficult to shake the car. It is characterized by that the crankshaft of the   diesel generator   can not rotate when it turns to a certain position, but can be retracted. At this time, besides checking the pressure reducing mechanism of diesel generator, check whether the meshing relationship of timing gear is wrong. For the diesel generator using electric starter, if the starting speed is extremely slow, most of the reasons are that the starter is weak, which does not mean that th...

During the operation of Cummins diesel generator, there must be some dirt. How to remove those dirt? In this article, Starlight Power Generation Equipment Co., Ltd. will briefly introduce some methods for   Cummins diesel generator   to remove dirt. 1. Oil washing method is often used to remove oil stains General parts are cleaned with diesel and dried with compressed air after cleaning. Detailed parts can be cleaned with diesel or petroleum. But after cleaning with diesel, if not repaired or assembled quickly, the parts should be soaked in diesel again to prevent rusting. 2. For parts with high oil stains, chemical cleaning can be used when equipment conditions permit. The parts can be placed in an alkaline solution, heated to 70-90 ℃, soaked for 10-15 minutes, removed, and washed clean with clean water (preferably hot water), and then dried with compressed air. In order to prevent corrosion of non-ferrous metal parts, the formula of the solution should be diff...

The silent diesel generator set is no exception. The removal rate of bituminous coal, carbon dioxide, carbon monoxide, hydrocarbons, nitrogen oxides from the tail gas of the silent diesel generator set by the environmental protection silent diesel generator set can reach more than 95%. Even at the moment of starting, the light blocking soot particles can not be seen, and its emissions exceed the Euro III standard. It can be used in urban high-density residential living areas to meet the strict requirements of environmental protection departments on exhaust emissions and noise levels of   quiet diesel generator sets . High altitude emissions are eliminated, and the impact of smoke exhaust pipe of silent diesel generator set on the overall beauty of the building is eliminated. The removal rate of bituminous coal, carbon dioxide, carbon monoxide, hydrocarbons and nitrogen oxides in the tail gas of the silent diesel generator set is more than 95%. Even at the moment of starting the sil...

  With the development of economic construction and the progress of equipment technology, Volvo diesel generator has become a common or necessary mobile energy device for various temporary construction sites and location shooting in the film and television industry, providing convenient power supply for the work site. However, it is also an environmental pollution source with prominent noise impact of Volvo diesel generator. No matter from the requirements of sound environment protection or on-site recording effect in the film and television industry, it is necessary to effectively reduce the noise of Volvo diesel generator. Because  Volvo diesel generator  is limited by volume, weight, thermal performance and modification process, it is very difficult to control the noise of the whole vehicle. Under the premise of ensuring that the appearance and operation of the Volvo diesel generator meet the specifications of the traffic management department,...

  The reaming of valve seat of Cummins Diesel generator is applicable to soft valve seat, which is usually carried out with valve seat reamer. A pair of valve seat reamers generally have four angles: 15 °, 30 °, 45 °, and 75 ° (or 60 °). The 30 ° and 45 ° reamers are further divided into two types: coarse blade and fine blade. Generally, the coarse blade has a tooth shape and is used for preliminary reaming. When a certain degree of reaming is achieved, a fine blade reamer is used for precision machining. Before reaming, it should also be noted that because the valve seat is reamed based on the valve guide, if the valve guide needs to be replaced or reamed, it should be done before the valve seat is reamed. Otherwise, if the valve seat is first reamed before replacing or fitting the guide tube, it may cause the center of the seat and tube to shift, resulting in the valve not being able to fit with the seat. The general reaming process of  Cummins Diesel generator  is as f...

In a humid environment, the insulation performance of diesel generator set and electrical components will be reduced due to moisture, and metal parts will be corroded, which will cause accidents in serious cases. Therefore, careful maintenance must be carried out. In this article, Starlight Power will share the maintenance methods of two  diesel generator sets  in humid environment. (1) Frequently pay attention to the insulation performance of the electrical components and circuits of the unit. When there is a fault, the insulation monitoring indicator light will light up, and the cause should be carefully checked and eliminated. If it drops due to moisture, the motor winding needs to be baked to restore its insulation performance. Usually, external heating method or current passing method inside the coil are used to evaporate the moisture in the motor winding; Or start the unit and adopt a gradual loading method to gradually increase the current inside the motor and driv...

Standardize the maintenance of diesel generator, ensure the good operation of diesel generator, and apply to the maintenance of various diesel generator. During the maintenance of diesel generator, attention shall be paid to the relative position and sequence of detachable parts, and marks shall be made if necessary. The structural characteristics of non detachable parts shall be noted, and the force for reinstallation shall be mastered. The maintenance cycle of   diesel generator   air filter is once every 50 hours of operation. When the transparent part of the display appears red, it indicates that the air filter of the diesel generator has reached the service limit, which should be cleaned or replaced immediately. After the treatment, gently press the button on the top of the display to reset the display. Loosen the iron ring of the diesel generator air filter, remove the dust collector and filter element of the diesel generator, and carefully clean the filter element ...
