Abstract
The utility model discloses an anti-burning safe automatic protector of an engine. A diesel oil outlet pipe is arranged at the front end of a shell; a diesel oil inlet is formed at the lower end of the diesel oil outlet pipe; an engine oil inlet is formed at the front upper end of the shell; spare oil passages are arranged on the front sides of the oil inlet and a control valve; an engine oil outlet is formed at the lower end of the shell; a plunger control valve is arranged in the shell; a plunger rod is arranged at the front end of the control valve; and a spring is arranged at the rear end of the control valve. When a failure occurs in an oil pump and oil is stopped to be supplied, the control valve is moved forwards under the elastic force action of the spring to push the plunger rod to forwards enter the diesel oil outlet pipe, the oil inlet is blocked, and the engine stops working because the oil is stopped to be supplied. The safe automatic protector has a simple structure, an ingenuous design, low production and processing costs and good using safety effect. The phenomena of burning and knocking caused by failure of a lubricating oil way of a diesel internal-combustion engine are thoroughly avoided since the anti-burning safe automatic protector is disclosed.
Description
Technical field
The utility model relates to a kind of explosive motor safety protection device, the automatic safe protective device of definite a kind of engine lubrication system of saying so.
Background technique
In the lubrication system of the various explosive motors of selling in the market and using; safety protection device all is set; the proper functioning of motor satisfies the lubricated of each parts by the oil pump that is arranged in the oil sump entirely; unit run up and the fully loaded working state under, the wearing and tearing of oil pump gear, rotor or mechanicalness fault take place often.Particularly in the bad farm machinery of working environment state, tile kilning, the phenomenon of smashing cylinder emerge in an endless stream, and the lighter need change crankshaft-link rod and watt carry out large repairs, and weight person will cause scrapping of whole motor.
Summary of the invention
Therefore there is great demand in people to the safety locking motion of engine lubrication system; up to now also do not find about relevant report of the present invention; the inventor is through a large amount of development tests; finally success work out a kind of protecting device with automatic protection functions, thereby finished the present invention.
The purpose of this utility model just provides a kind of motor tilt-burning proof safety automatic safety device, causes tile kilning, smashes the cylinder phenomenon because of lacking machine oil and oil pump catastrophic failure preventing, in time shuts down the repair and replacement oil pump, ensures the safe in utilization of motor.
Scheme of the present utility model is made up of protecting device housing, plunger control valve and spring, its structural feature is that the protecting device housing is made as cylindrical body, the front end of housing is provided with the diesel oil oil outlet tube, the lower end of diesel oil oil outlet tube is provided with the diesel oil filler opening, the rear end of housing is provided with bonnet, bonnet and housing are by being threaded, the preceding upper end of housing is provided with the machine oil filler opening, the front side of filler opening and control valve is provided with standby oil duct, the lower end is provided with oil outlet, the plunger control valve is housed in the housing, and the front end of control valve is provided with plunger rod, and the rear end is provided with spring.
Under normal working state, machine oil is entered in the housing of protecting device by the filler opening of protecting device upper end, oil outlet through the lower end enters pipeline and finishes normal engine oil passage circulation, under the pressure of oil pump, the pressure machine oil that circulates backs down the plunger control valve and overcomes the spring force of right-hand member, makes the turnover oil duct of machine oil remain unimpeded.Diesel oil turns to oil outlet tube fuel normally to be provided for motor by the diesel oil filler opening of protecting device front end, and normal working of engine is done manual work.When oil pump broke down fuel cut-off, the Oil passage of protecting device front side had lost pressure.Control valve moves forward under the elastic force effect of spring, promotes plunger rod and moves forward into the diesel oil oil outlet tube, stops up filler opening, and the motor oil-break is shut down.
The utility model is simple in structure, designs ingeniously, and the production and processing cost is low, and is safe in utilization effective, and the appearance of this product is smash the cylinder phenomenon with the tile kilning of thoroughly having avoided diesel engine to cause because of the lubricating oil path fault, has also filled up the blank of the domestic and international same industry simultaneously.
Be described in further detail below in conjunction with accompanying drawing.
