Why Does the Diesel Generator Set Leak Oil

What is the cause of oil leakage in diesel generators?  Now let's talk about that with you.  Over 80% of oil spills are caused by corrosion and aging of oil seals.  Because rubber seals lose plasticizer due to frequent temperature changes caused by hot and cold alternation, the harm is deformation of seals, and even serious fracture oil leakage.  Some diesel generator manufacturers do not meet the standard of technology, poor maintenance operation technology, assembly and disassembly machine is not professional.  

Why does the diesel generator set leak oil?  These tests must be bookmarked!  

In daily communication with customers, they pay more attention to the performance indicators, well-known brands, fuel economy and so on.  In which fuel economy is also the key technical indicators of many customers in the purchase of units, generally speaking, diesel generator fuel consumption is determined by the following factors: diesel generator well-known brand, not the same as the well-known brand production process is not the same, so the consumption of oil indicators are not the same;  

The leakage of oil and diesel oil not only increases the consumption of oil, but also makes it difficult to clean the engine surface after bonding with soot.  

Replace it on time, or the unclean diesel will leak into the three fine parts, and spray into the combustion chamber will make the fine parts and cylinder parts damaged and accelerated.  

Causes of diesel leakage:  

One is to check the oil type, oil quantity, oil quality can meet the provisions.  

Two is the diesel engine of a variety of parts of the combined surface can be smooth leveling, production processing size can meet the requirements.  Sand turning parts and casting parts should be free from sand holes and air holes. Can all kinds of paper pads, sealing strings, oil seals and screws meet the requirements and tighten?  

Three is the diesel engine lubrication can be smooth and meet the requirements (air-cooled diesel engine servo column return oil hole is very important.  

Fourth, the diesel engine without negative pressure should also check whether the breathing can be unimpeded and in accordance with the provisions, whether the cylinder can be gas to the crankshaft, resulting in spray and leakage of oil.  

Fifth, the machine temperature can not be too high, cooling, heat dissipation performance indicators can be good.  Engine oil leakage must not be ignored, be sure to go to maintenance inspection on time to prevent greater loss.  

Diesel engine oil leakage phenomenon is also used to, how to save fuel money, according to the following situation to carry out a reasonable solution.  

Nozzle return: nozzle is a delicate part.  If the diesel engine is applied unclean diesel or the machine is applied for a long time, it will return to the oil due to the damage of the nozzle.  However, because replacing the nozzle costs a lot of money, in order to prevent oil leakage, the oil can be led back to the tank according to the return pipe, or into the diesel filter.  If the return pipe is damaged, a piece of plastic pipe can be used to guide the oil into a spare vessel, through the filtration system and then back into the tank.  

Oil leakage: can be properly solved in their respective situations: the gasket of the hollow screw of the pipeline is uneven, the gasket can be removed, ground off and padded again. If the problem can not be solved, the gasket can be removed or replaced with a thick soft plastic material cut into a gasket;  Plastic pipeline and metal joint oil leakage, most of the plastic pipeline hard bottom or broken, can be cut to hard bottom, broken part, then hot hot soft, while hot installed on the metal joint, and then tied with metal wire;  Metal pipeline broken oil leakage, can be broken with brazing welding.  In addition, in order to prevent the pipeline from breaking, when installing the pipeline, the radian should be suitable, and there is no need to install it by hard pulling, and the pipe body should not touch the fuselage to prevent abrasion.  

Valve chamber cover oil leakage: when the valve chamber cover is installed, if the fastening force is too large, it is easy to cause deformation and oil leakage.  At this time, the valve chamber cover can be removed from the oil leak, and the contact surface can be restored to smooth with the wooden rod carefully pounded, and then the gasket can be installed.
