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 Grease pump 3 and oil sump 4, the oil site of engine are respectively connected by the first branch pipe(tube) 5 with the first pipeline 6, and first Pipeline one end closure, the other end are connected with lubricant filtering device, and lubricant filtering device is connected by second pipe 7 with machine band grease pump, Machine band grease pump is communicated in oil sump by the 3rd pipeline 8;Pre-lubrication oil fuel tank passes through the 4th pipeline 12 and pre-lubrication oil Pump is connected, and pre-lubrication oil pump is communicated to the overfall of low level tank bottoms, low level fuel tank and oil sump by the 5th pipeline 13 Between be connected by the 6th pipeline 14, be connected between second pipe and the 4th pipeline by the 7th pipeline 15, the 7th pipeline Stop valve 16 is provided with, the first check valve 17 is additionally provided with 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 provided with ventilative check valve 18, can with the cleaned air after suction filter, but Air and lubricating oil can not flow out from this check valve, meanwhile, negative pressure when lubricating oil flows down by deadweight can just open this valve, with This, can exclude clean when needing and discharging the lubricating oil in pre-lubrication oil fuel tank.
Further, stop valve is automatically controlled or manual control.
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, low liquid level warning sensor 19 is set in low level fuel tank.
Further, pressure sensor 20 is set in pre-lubrication oil fuel tank.
Further, low level fuel tank sets high position sensor.
The volume of pre-lubrication oil fuel tank should be able to meet following condition: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 present invention is as follows:
(1) interface position from pre-lubrication oil fuel tank to engine is located at:Before machine band grease pump and lubricant filtering device Pipeline, stop valve is set from pre-lubrication oil fuel tank to the pipeline engine, this stop valve is opened during pre-lubrication, 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 can not be from this Oil pump flows into oil sump, but passes through the oil site in lubricant filtering device inflow body;Once engine starts, oil site can be at once Oil film is established, each oil site of lubricating oil continuous lubrication that then machine pumps with oil pump, so as to avoid starting under cold state Worn caused by machine dry friction.
Overvoltage protection mechanism, i.e. pressure-reducing valve are generally provided with lube oil filter, i.e. pressure exceedes 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 exceed overfall, Low level fuel tank then can be flowed into from overfall;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) set pipeline to connect from low level fuel tank to pre-lubrication oil fuel tank, and equip a pre-lubrication oil pump, every time After engine starts successfully, it can be delayed a period of time, so that lubricating oil flows into low level fuel tank;Or set in low level fuel tank high-order Sensor, reach setting liquid level pre-lubrication oil pump and work, lubricating oil is pumped into pre-lubrication oil fuel tank, when pre-lubrication oil fuel tank reaches During to setting pressure or liquid level, pre-lubrication oil pump is stopped.
(4) engine prestart, or engine shutdown, more than starting button for a period of time, is pressed, pre-lubrication is oily every time Fuel tank is opened to the stop valve between engine, and the lubricating oil of pre-lubrication oil fuel tank flows into engine lubrication oil duct and engine is entered 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 Change.
Traditional pre-lubrication oil pump is interrupter duty when shutting down, and directly the oil site of engine is lubricated, engine This pre-lubrication does not have any effect when inoperative, and pre-lubrication is worked only its prestarting 1 hour with Interior work, and the pre-lubrication oil pump capacity generally selected is smaller, it is necessary to be lot more time to establish required pre-lubrication oil Pressure.
The pre-lubrication oil pump of this system directly moistens unlike traditional pre-lubrication oil pump to the oil site of engine 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 starting button, then prelubricated stop valve is opened at once, pre-lubrication Oil can flow to oil site quickly with higher pressure and flow, complete pre-lubrication action, and now engine can also start quickly, from And reaching timely pre-lubrication effect, its effect is obvious.
