Technical Field
The utility model particularly relates to a self-circulation device of a diesel engine, and belongs to the technical field of high-pressure diesel engine systems.
Background
The diesel engine in the steel industry is indispensable equipment of an emergency system, the diesel engine needs to be tested and maintained at ordinary times, the high-pressure diesel engine needs to be operated under load because of no clutch, water cannot be supplied out during the test of the diesel engine, water cannot circulate to cause pressure build-up, the impeller of a diesel engine pump is greatly damaged, and the service life of the equipment is shortened; so that the emergency function can not be realized during emergency, water can not be supplied to the blast furnace, and the blast furnace is stopped.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a self-circulation device of a diesel engine, wherein pipelines are additionally arranged on two sides of a pump of the diesel engine to form self-circulation, so that the pressure build-up phenomenon is eliminated, the service life of equipment is prolonged, and the emergency use of the equipment is ensured.
The utility model relates to a diesel engine self-circulation device, which comprises a diesel engine and a diesel engine pump arranged with the diesel engine; the input end of the diesel engine pump is connected with a water inlet short joint; the output end of the diesel engine pump is connected with a water outlet short joint; the water inlet short joint and the water outlet short joint are connected through a flow guide pipe; the guide pipe is connected with a valve in series; add at diesel engine nipple joint of intaking and play water nipple joint department and establish the water conservancy diversion pipeline, open the valve in the middle of the honeycomb duct when the diesel engine is tried on the machine, the leading-in nipple joint department of intaking of water that can't circulate makes it form the self-loopa when the diesel engine is tried on the machine, avoids pressing because of holding back the harm that causes the diesel engine pump, has prolonged the life of equipment, practices thrift equipment cost, makes it play real emergent effect, has guaranteed the normal water supply of blast furnace.
Furthermore, a tee joint is connected in series with the water inlet short section and the water outlet short section; the third ends of the two tee joints are connected through a guide pipe; and valve bodies are arranged at the output ends of the water inlet short section and the water outlet short section.
Furthermore, a tee joint is connected in series with the water inlet short section and the water outlet short section; the flow guide pipe comprises a first flow guide pipe and a second flow guide pipe; one end of the first guide pipe and one end of the second guide pipe are connected into the closed water tank, and the other end of the first guide pipe and the other end of the second guide pipe are connected into the third end of the tee joint through the quick connector and the valve.
Compared with the prior art, the diesel engine self-circulation device provided by the utility model eliminates the pressure build-up phenomenon, ensures the emergency use of equipment, provides a powerful guarantee for the normal production of a blast furnace, and also prolongs the service life of the equipment.
