The internal combustion engine is the main power source for automobiles and construction machinery. The internal combustion engines mainly include gasoline engines and diesel engines. Diesel engines are widely used in trucks because of their high thermal efficiency, wide application range, and fuel economy. In particular, it can meet the needs of construction machinery operating conditions, therefore, most of the construction machinery uses diesel engines as a power source. However, if the use of improper maintenance is prone to overheating. The internal combustion engine for construction machinery is more prone to overheating due to its complex working conditions and harsh working environment. If the overheating fault is not eliminated in time, it will cause great harm, which will easily cause damage to the engine, increase fuel consumption, and reduce output power. As a repairman, during the repair process, it often encounters the treatment of an internal combustion engine overheating fault. So how to quickly and accurately find the cause of overheating faults and eliminate them in time is very important. This is of great significance for giving full play to the economical and dynamic nature of mechanical equipment and improving its service life. The dangers of internal combustion engine overheating and the causes of the internal combustion engine Overheating faults are very harmful. Overheating for a long time can easily lead to deformation, melting, jamming and pulling of cylinders, which can increase fuel consumption and reduce output power. There are many causes of overheating of the internal combustion engine, such as heavy loads on ramps and working in hot summers with high ambient temperatures and desert plateaus. The cooling system is affected and cannot function adequately. Long-term overloading and high-speed operating conditions . These are caused by the influence of the operating environment factors of construction machinery and can generally be overcome by improving the operating conditions and reasonable operations. For overheating of the engine caused by a fault in the internal combustion engine, inspection and repair are required to restore normal operation. Overheating caused by internal combustion engine failure mainly includes inadequate cooling water in the cooling system, excessive fouling of the cooling water channel around the cylinder liner, failure of the thermostat, poor performance of the radiator, abnormal exhaust valve clearance, incorrect valve timing, and ignition timing failure factors. . Therefore, in the event of an overheating fault in the internal combustion engine, scientific analysis should be made based on the fault phenomenon and the cause of the fault should be identified in a timely manner.
Couplings are used to connect two joints of TUBING coupling or CASING pipe together.
Couplings are short length of heavy wall pipe with the same threads on each end.
The steel coupling is mainly used to connect oil pipes in pil drilling.
This product can be used to connect the shafts of units that are
manufactured separately.
It can fit the misalignment of the shafts or introduce mechanical flexibility.
The pipe coupling is capable of reducing the transmission of shock losds from one shaft to another.
It can also introduce protecyion against overloads.
The steel coupling can be used to alter vibration characteristics of
rotating units.
Pipe coupling is also used to connect drilling par and driven part.
