Abstract
An engine main oil gallery oil pressure protecting device comprises an energy accumulator, a supporting frame, an oil inlet-outlet pipe, a main oil gallery oil inlet pipe, one-way valves, an oil filter oil outlet pipe and an oil filter, wherein the main oil gallery oil inlet pipe is respectively connected with a main oil gallery, the oil filter and the energy accumulator which is arranged on a unit chassis through the supporting frame, and the main oil gallery oil inlet pipe and the oil filter oil outlet pipe which is connected with the oil filter are provided with the one-way valves. The engine main oil gallery oil pressure protecting device has the advantages of being capable of providing pressure protection of a lubrication system of an engine, improving lubrication and cooling performance of the engine, reducing maintaining cost, effectively preventing the fact that the engine is stopped suddenly because of uncertain factors to cause damage to the engine because the engine is stable to operate, and being simple in structure, convenient to use, safe, reliable, durable, low in cost and the like, and is widely applied to the lubrication system of the engine.
Description
Technical field
The utility model relates to the engine lubrication oil supply system, particularly a kind of motor main oil gallery oil pressure protective device.
Background technique
During engine operation, a lot of driving parts all are to do the high speed relative movement under very little gap, such as crankshaft main journal and main bearing, crank pin and connecting rod bearing, cam journal and camshaft bearing, piston, piston ring and cylinder wall surface, each kinematic pair of distribution device and driving gear pair, pressurized machine bearing etc.The function of lubrication system be exactly when engine operation oil delivery to the friction surface of whole driving components, thereby reduce surface friction drag, alleviate component wear, to reach the purpose that improves engine operation reliability and durability.Main oil gallery is the important component part of lubrication system, is used for to each lubricant housings conveying lubricant oil.Traditional lubrication system exists following shortcoming or deficiency: 1. after motor hinders unexpected shutdown for some reason, when the main oil gallery lubricating oil pressure drops to rapidly zero, can not in time provide lubricant oil to motor; 2. important spare part especially each friction pair of motor lubricate because can not get, often cause each moving parts working surface scaling loss of motor or badly damaged accident occur, cause motor to turn round.
Summary of the invention
The purpose of this utility model provides a kind of motor main oil gallery oil pressure protective device; the combined mechanism that is made of main oil gallery oil inlet pipe, oil filter oil outlet tube connection accumulator, one-way valve is installed in employing between oil filter and main oil gallery; both effectively prevented important spare part especially each friction pair of motor because can not get the lubricated generation that causes the badly damaged accident of motor; improve the working life of motor complete machine, the shortcoming or the deficiency that effectively overcome again or avoid existing in the above-mentioned prior art.
Motor main oil gallery oil pressure protective device described in the utility model comprises accumulator, support, oil inlet and outlet pipe, main oil gallery oil inlet pipe, one-way valve, oil filter oil outlet tube, oil filter.Described main oil gallery oil inlet pipe is connected with main oil gallery, oil filter, accumulator respectively, and accumulator is installed on the unit chassis by support, on the oil filter oil outlet tube that the main oil gallery oil inlet pipe is connected with oil filter one-way valve is installed.
Wherein, described energy accumulator housing is cylinder-like structure, and inner chamber is connected with the main oil gallery oil inlet pipe by the oil inlet and outlet pipe.Described oil filter is connected with the main oil gallery oil inlet pipe, and is connected with accumulator by the oil inlet and outlet pipe by oil filter oil outlet tube, one-way valve.
The utility model has following advantage compared with prior art:
1, can provide the engine lubrication system pressure protect, convenient operation personnel in time pinpoint the problems;
2, improve engine lubrication, cooling capacity, reduce maintenance cost;
3, motor is stable, can effectively prevent the infringement that motor causes motor because of suddenly shutdown of uncertain factor;
4, simple in structure, system is esy to use, safe and reliable durable, and is with low cost.
Description of drawings
Fig. 1 is a kind of example structure schematic diagram of the present utility model.
Embodiment
Consult Fig. 1, a kind of motor main oil gallery oil pressure protective device comprises accumulator 7, support 6, oil inlet and outlet pipe 5, main oil gallery oil inlet pipe 4, one-way valve 3, oil filter oil outlet tube 2, oil filter 1.Described main oil gallery oil inlet pipe 4 is connected with main oil gallery, oil filter 1, accumulator 7 respectively, accumulator 7 is installed on the unit chassis 8 by support 6, on main oil gallery oil inlet pipe 4 and the oil filter oil outlet tube 2 that oil filter 1 is connected one-way valve 3 is installed.
Wherein, described accumulator 7 shells are cylinder-like structure, and inner chamber is connected with main oil gallery oil inlet pipe 4 by oil inlet and outlet pipe 5.Oil filter 1 is connected with main oil gallery oil inlet pipe 4 by oil filter oil outlet tube 2, one-way valve 3, and is connected with accumulator 7 by oil inlet and outlet pipe 5.
Accumulator 7 is filled with nitrogen, and inflation pressure is 0.2MPa, during engine work, lubricant oil is divided into two-way through behind the one-way valve 3, and one the tunnel directly enters the body main oil gallery, another road enters accumulator 7 and stores, and stores lubricating oil pressure identical with main oil gallery pressure.When oil pump or lubrication system miscellaneous part break down, when the main oil gallery lubricating oil pressure is lower than normal operating pressure or drops to rapidly zero, working pressure when accumulator 7 can be by the motor normal state in time provides about lubricant oil 3-5 minute to motor, play the effect of each friction pair working surface of Cooling and Lubricator motor, effectively prevent important spare part especially each friction pair of motor because can not get the lubricated generation that causes the badly damaged accident of motor, the working life of greatly improving the motor complete machine.
