Diesel Generator Tech

Today we are going to introduce the installation inspection, material quality control and installation of diesel generator sets in water conservancy projects, hoping to help you. Environmental inspection before installation of  diesel generator set Before the installation of diesel generator set, all civil works shall meet the following requirements in addition to the requirements of technical specifications. 1. The environment in the machine room is clean, well ventilated and dry; 2. There should be no articles that can produce acid, alkali and other corrosive gases in the machine room; 3. Ventilation and exhaust facilities shall be installed; 4. There shall be no other objects in front of the radiator of the unit. Material quality control of diesel generator 1. The capacity specification of diesel generator set must meet the design requirements. 2. Check the main engine, accessories, special tools, spare parts and attached technical documents according to the packing list, check ...

  In order to prevent the   diesel generator   from rusting, when the product leaves the factory, its internal and external oil seals have been installed. Therefore, after the installation of the new unit is completed and meets the installation technical requirements, it must be unsealed before starting, otherwise it is easy to cause the unit failure.   Remove the oil seal as follows: ① Heat the diesel oil to about 50 ℃ for cleaning and removing the antirust oil outside the engine.   ② Open the door cover on the engine body and fuel pump to see if there is corrosion or other abnormal phenomenon inside.   ③ Turn the crankshaft manually to slowly rotate, observe the movement of the crankshaft connecting rod, fuel pump camshaft and plunger, and there should be no jamming or inflexibility. Move the speed control handle back and forth several times from low speed to high speed, and observe the movement of the rack and core sleeve should be free of jamming. ④ Hea...

  It is normal that Ricardo diesel generator will be worn after being used for a period of time. However, if Ricardo diesel generator has unreasonable excessive wear, this situation is abnormal. It may be due to improper use by users, or it may be due to some faults of   Ricardo diesel generator . If the diesel oil of Ricardo diesel generator contains sulfur or other impurities, acid and other corrosive substances will be produced during combustion, which will accelerate the wear of the cylinder of Ricardo diesel generator. If there are too many heavy components in the diesel oil of Ricardo diesel generator, it is easy to form carbon deposits after combustion, which will cause the wear of the cylinder of Ricardo diesel generator. Ricardo diesel generator uses wear-resistant piston ring and cylinders. The viscosity of Ricardo diesel generator diesel can be used for the formation of mixture and the work of oil supply equipment. For Ricardo diesel generator lubricating oil, the b...

  How much do you know about the oil system of diesel generator set? The west system of diesel generator set includes oil tank, diesel Frega filter, oil-water separator, high-pressure oil pipe, fuel delivery pump, fuel injection pump, fuel injector, low-pressure oil pipe and return oil pipe. The fuel tank is a container for storing diesel oil. The fuel tank is generally welded and connected by us using steel plate stamping technology. The oil filler is located at the top of the oil tank, and the filter screen is generally installed under the oil filler. In order to avoid some vacuum in the internal management of the tank, the upper part of the tank cap is generally equipped with a breather. Enterprises at the bottom of the oil tank are generally equipped with oil drain. Secondly, diesel filter is usually installed before the pump to remove large particulate impurities of diesel generator set. There is a paper filter type, slit metal, chip, and similar grid. The fine filter of the...

The oil circuit system of Cummins diesel generator set includes oil tank, filter, oil-water separator, high-pressure oil pipe, fuel transfer pump, fuel injection pump (including governor), fuel injector, low-pressure oil pipe and return oil pipe. The tank is filled with precipitated and filtered diesel, which is the diesel fuel pump and the person pumped out from the tank. The diesel Frega filters the impurities and enters the injection pump. The high pressure and diesel output from the self-injection pump are injected into the combustion chamber through the high pressure system oil pipe and injector. Since the fuel supply of the pump is far greater than that of the fuel injection pump, the excess diesel oil is returned to the pump through the return pipeline. The fuel pump from the fuel tank to the population of this oil is called low-pressure oil. The low-pressure control oil circuit is only used to supply filtered fuel to the fuel injection pump. The oil pressure from the fuel injec...

  Today, we will briefly introduce how to fill diesel fuel for Volvo generator sets. The diesel engine is the core component of Volvo generator set and the heart of the whole operation. If there is no oil, it should be refueled in time. But do you know the correct refuelling method? Is it true that diesel fuel will lead to fuel tank? Often these familiar details are the factors that lead to component damage, and even directly affect the service life of Volvo generator unit components and even the entire unit. Volvo generator sets  feel that the fuel supply advance angle should be earlier: some mobile power station operators often prefer to move forward when adjusting the fuel supply advance angle of diesel engines, and some even exceed the specified value by 2-3 degrees. They feel that if the fuel supply advance angle is adjusted forward, the engine will work vigorously. However, they do not know that the premature fuel supply advance angle is equally harmful to the work of th...

Epoxy resin bonding method and screw filling method for cylinder block and cylinder head of Perkins diesel generator set, and sealing method for cylinder block and cylinder head of Perkins diesel generator set. If the crack is long or there are holes in the parts of the cylinder block and cylinder head of the Perkins diesel generator set where the stress is small, use reinforcing plates around the damaged parts of the   Perkins diesel generator set . Drill holes at the end of each crack of Perkins diesel generator set to limit the extension of the crack. Cut 3-5mm thick copper plate or 1.5-2mm thick iron plate into patches similar to the fracture contour, and the area around the fracture is greater than 15-20mm. If there is a bulge on the disconnected surface of Perkins diesel generator set, the bulge of the same shape shall be knocked out on the terminal block, so that the whole terminal block of Perkins diesel generator set can match the surface of the wiring part. Press the fill...
