A kind of new work engine pre-lubrication system as shown in the figure, including pre-lubrication oil fuel tank 9, pre-lubrication oil pump 10 and low level Fuel tank 11, pre-lubrication system need to be used in combination with engine system, and engine system includes engine 1, lubricant filtering device 2, machine band The oil site of grease pump 3 and oil sump 4, engine is respectively connected by the first branch pipe(tube) 5 with first pipe 6, and first Pipeline one end is closed, the other end is connected with lubricant filtering device, and lubricant filtering device is connect by second pipe 7 with machine band grease pump, Machine band grease pump is connected to by third pipeline 8 in oil sump;Pre-lubrication oil fuel tank passes through the 4th pipeline 12 and pre-lubrication oil Pump is connected, and pre-lubrication oil pump is connected to low level tank bottoms, the overflow port of low level fuel tank and oil sump by the 5th pipeline 13 Between be connected by the 6th pipeline 14, be connected by the 7th pipeline 15 between second pipe and the 4th pipeline, the 7th pipeline It is equipped with shut-off valve 16, the first check valve 17 is additionally provided on the 4th pipeline, the first check valve is located at pre-lubrication oil pump and the 7th pipe Between the junction in road, pre-lubrication oil fuel tank provides pre-lubrication oil to engine.
Further, pre-lubrication oil pump is rotator type or gear type.
Further, pre-lubrication oil top of oil-tank is equipped with ventilative check valve 18, can with the cleaned air after suction filter, but Air and lubricating oil cannot be flowed out from this check valve, meanwhile, negative pressure when lubricating oil is flowed down by dead weight can open this valve, with This, can exclude clean when needing the lubricating oil being discharged in pre-lubrication oil fuel tank.
Further, shut-off valve is automatically controlled or manually controls.
Further, pre-lubrication oil pump only just works when needing to be pumped into lubricating oil to pre-lubrication oil fuel tank, when pre- Lubricating oil tank is just stopped when reaching required pressure or lubricants capacity.
Further, pre-lubrication oil fuel tank is vapour-pressure type pre-lubrication oil fuel tank.
Further, setting low liquid level warning sensor 19 in low level fuel tank.
Further, pressure sensor 20 is set in pre-lubrication oil fuel tank.
Further, high position sensor is arranged in low level fuel tank.
The volume of pre-lubrication oil fuel tank should be able to meet the following conditions:The lubricating oil of discharge can fill up machine band grease pump to institute There is the tube cavity between oil site, can also be filled up in the state of lube oil filter sky, that is, need suitable surplus.
The operation principle of the engine pre-lubrication system of the utility model is as follows:
(1) it is located at from the interface position on pre-lubrication oil fuel tank to engine:Before machine band grease pump and lubricant filtering device Pipeline, shut-off valve is set from pre-lubrication oil fuel tank to the pipeline engine, when pre-lubrication opens this shut-off valve, makes lubrication Oil flows into engine from pre-lubrication oil fuel tank;Common machine is rotor and gear type with grease pump, and lubricating oil cannot be from this Oil pump flows into oil sump, but the oil site in body is flowed by lubricant filtering device;Once engine start, oil site can be at once Oil film is established, each oil site of lubricating oil continuous lubrication that then machine is pumped with oil pump, to avoid starting under cold state Abrasion caused by machine dry friction.
Overvoltage protection mechanism, i.e. pressure reducing valve are usually provided on lube oil filter, i.e. pressure is more than what lubricant filtering device allowed After pressure, lubricating oil can be bypassed into oil sump, therefore without worrying that pre-lubrication system can destroy the lubricating system of engine Normal work.
(2) after flowing into oil sump due to prelubricated lubricating oil, the oil level of oil sump rises, once it is more than overflow port, Low level fuel tank then can be flowed into from overflow port;Low liquid level warning sensor is set in low level fuel tank, pressure is set in pre-lubrication oil fuel tank Force snesor, once the liquid level in this pre-lubrication oil fuel tank reduces and pre-lubrication oil fuel tank.
(3) from low level fuel tank to pipeline connection, and one pre-lubrication oil pump of equipment are arranged pre-lubrication oil fuel tank, every time It after engine start success, can be delayed a period of time, so that lubricating oil flows into low level fuel tank;Or it is arranged in low level fuel tank high-order Sensor reaches setting liquid level pre-lubrication oil pump and works, lubricating oil is pumped into pre-lubrication oil fuel tank, when pre-lubrication oil fuel tank reaches When to setting pressure or liquid level, pre-lubrication oil pump is stopped.
(4) every time before engine start or engine to shut down be more than a period of time, press starting button, pre-lubrication oil Fuel tank is opened to the shut-off valve between engine, the lubricating oil of pre-lubrication oil fuel tank flow into engine lubrication oil duct to engine into Row pre-lubrication, engine enter back into progress of starting sequence.
(5) every time more oil change when need the lubricating oil in low level fuel tank and pre-lubrication oil fuel tank together more It changes.
Traditional pre-lubrication oil pump is interrupter duty when shutting down, and is directly lubricated to the oil site of engine, engine This pre-lubrication does not have any effect when inoperative, and to pre-lubrication work only its prestarting 1 hour with Interior work, and the pre-lubrication oil pump capacity usually selected is smaller, takes a long time that required pre-lubrication oil could be established Pressure.
The pre-lubrication oil pump of this system directly moistens the oil site of engine unlike traditional pre-lubrication oil pump It is sliding, but for conveying lubricating oil to pre-lubrication oil fuel tank and making up to suitable pressure, and this pre-lubrication system is sealing , pressure can be kept for a long time, once pressing engine start button, then prelubricated shut-off valve is opened at once, pre-lubrication Oil can flow to oil site quickly with higher pressure and flow, complete pre-lubrication action, and engine can also start quickly at this time, from And reaching timely pre-lubrication effect, effect is obvious.
