Abstract
The utility model relates to a safety control device, which can be used under the condition that the lubrication system of an engine dose not work, the main oil passage of the engine is connected with an oil pressure switch which controls the on-off of the oil inlet pipe of the diesel engine by electromagnetic valve, and the oil pressure switch is connected in series between a switch K1 < 1 > and the electromagnetic valve. When oil pressure lacks, the oil pressure switch cuts, and the power source of a sucking-pulling coil L < 1 > in the electromagnetic valve and a keeping coil L < 2 > is cut. A valve K is closed by a pull rod L, the diesel engine is in a cutting state, and the diesel engine can immediately and automatically flame out. The utility model is suitable for being used in the flameout of a diesel engine by the method that the on-off of a fuel inlet pipe is controlled by the electromagnetic valve (is not cut out by a flameout drawbar). The utility model can protect the engine, and the utility model has simple structure.
Description
Safety control when the utility model relates to a kind of engine lubrication system oil pressure fault, especially the auto extinguishing protective gear of the diesel engine of doing flameout switch with solenoid valve when the machine oil decompression.
In the prior art, when lubricating system of diesel oil engine breaks down when causing in the main oil gallery inorganic oil, generally be to indicate and the engine oil pressure warning light is bright reports to the police by fuel level indicator, this needs the driver to note pressure gauge and tutorial light constantly, lack automatic safety device Chinese patent application CN2124311U and disclose a kind of " oil pressure scram device ", be by engine oil pressure size control piston bar, the engine misses pull bar of piston rod on slide bar control throttle draws back, make engine stalling, this device for mechanical complex structure, and be unsuitable for flame-out diesel engine (diesel engine that does not have flame-out pull bar) with electromagnetic valve switch control fuel oil oil inlet pipe break-make; Chinese patent application 95223849.7 is that " a kind of petrol engine machine oil decompression check piece " is when the machine oil decompression, cut off the low-voltage circuit of ignition system of gasoline engine by the oil pressure switch that links to each other with the motor main oil gallery, make engine stalling, this device only is applicable to petrol engine.
The purpose of this utility model is to obtain a kind of diesel engine lubricating oil decompression check piece, is the diesel engine that is applied to electromagnetic valve switch control fuel oil oil inlet pipe break-make, makes the diesel engine auto extinguishing when lubricating oil pressure is not enough.
The purpose of this utility model is achieved in that
A kind of diesel engine lubricating oil decompression check piece, by the break-make of the oil pressure switch that links to each other with the motor main oil gallery through electromagnetic valve diesel engine in-line, the nylon connecting sleeve and the motor main oil gallery of oil pressure switch join, the oil circuit control piston that cavity in nylon connecting sleeve and the sleeve pipe constitutes, the upper and lower motion of piston rod, piston rod is around with spring, sleeve pipe is outer to link to each other with contact point arm through felt pad, and oil pressure switch is connected on switch between the solenoid valve through contact and piston rod upper end for contact.
Oil pressure switch is connected on switch between pull in winding and the guarantor's bit line circle through contact and piston rod upper end for contact.
Switch is to also being connected to K switch between the solenoid valve
2
K switch
2Be the time relay.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Accompanying drawing is the utility model diesel engine lubricating oil decompression check piece structural representation.
Referring to accompanying drawing, E is a storage battery, and A is an ammeter, K
1Be switch, oil pressure switch is connected on switch K
1And between the solenoid valve.Oil pressure switch is to be joined by nylon connecting sleeve 8 and motor main oil gallery, cavity in nylon connecting sleeve 8 and the sleeve pipe 7 constitutes oil circuit, sleeve pipe 7 constitutes the pistons work chamber with nut 2, piston 6 and piston rod 4 can move up and down in its active chamber, there is seal ring 5 piston 6 outsides, contact point arm 9 is fixed on sleeve pipe 7 outsides by screw 11, between sleeve pipe 7 and the contact point arm 9 felt pad 10 is arranged.This oil pressure switch is that contact is serially connected in switch K with contact 1 and piston rod 4 upper ends
1And between the solenoid valve, when the diesel engine proper functioning, be full of machine oil in the oil circuit of oil pressure switch, and piston 6 being overcome on the deadweight and the elastic force of spring 3 move, piston rod 4 withstands on the top and contacts the pull in winding L in the solenoid valve with contact 1
1With guarantor's bit line circle L
2Energising, the elastic force that the magnetic field of generation makes iron core F overcome spring S is pulled to right-hand member by suction, by pull bar L valve K is opened, and the diesel oil in the fuel tank T is through high pressure oil pump P input fuel pipe; Simultaneously, pull in winding L
1Recloser K
3Disconnect, protect bit line circle L
2The number of turn be far smaller than L
1, protect bit line circle L
2All the time energising, the diesel engine in-line is in unobstructed state and proper functioning.
When inorganic oil in the main oil gallery or engine oil pressure deficiency, piston rod 4 tops and the contact 1 of oil pressure switch separate pull in winding L
1With protect bit line circle L2 outage, iron core F is under the effect of spring S, pushing drawing rod L moves to left immediately, K closes with valve, the diesel engine in-line is in off state and auto extinguishing immediately.
Oil pressure switch also with time relay K switch
2Parallel connection, K
2Be installed in the operator cabin, because just during the starting diesel engine, diesel engine speed is low, the lubrication system engine oil pressure can't be set up, and at this moment enables the time relay K switch in the operator cabin
2With 3～5 seconds of oil pressure switch short circuit, start back time relay K switch
2Automatic disconnection, oil pressure switch is devoted oneself to work.Simultaneously, K
2Under diesel engine lubricating oil decompression auto extinguishing situation, can make emergency cock and use.
Protective gear when the utility model provides a kind of novel diesel machine machine oil decompression; promptly on the diesel engine that adopts solenoid valve oil circuit switch, oil pressure switch is set; when the machine oil decompression; solenoid valve is cut off the power supply automatically; cut off oil circuit; make not reason machine oil decompression and damaging of diesel engine, can protect motor, and simple in structure.
