Description
Technical field
This utility model relates to lubricating system field, a kind of lubricating system with electronic relief valve.
Background technology
Positive displacement centralized lubrication technology is high with its reliability, oil drain quantity accurately, low cost and to lubricating pump and pipeline system
System pressure requirements not high is widely used in lubrication technical field, and positive displacement centralized lubricating system includes release
Formula and adding pressure type two kinds, for ensureing that positive displacement centralized lubricating system separator normally works, the requirement when specific works of this technology
After lubricating pump operating terminates, the necessary pressure release completely of the oil pressure at working connection nearly separator group, separator could supply to individual oil site
Oil.The most in such an embodiment, being provided with a pump pressure-relief valve in fuel tank at pump discharge, after system is out of service, relief port is certainly
Moving and open, working connection fluid flows back to fuel tank automatically, finally makes oil pressure release at working connection nearly separator group.The most normal
The pumping plant pressure-relief valve seen mostly is Germany's VOGEL KFU2-40 type commercial car vehicle base plate centralized lubrication system and Patent No.:
The patent of invention " the self-balancing type pump pressure-relief valve of lubricating system " of ZL00237891.9.And Patent No.: ZL2013205790233
Disclosing a kind of by motor reversal, it not only realizes the centralized lubrication pumping plant of pipeline release, and eliminates pressure-relief valve machine on pump
Structure, but there is also the problem that in the system that main oil pipe road is longer, at nearly separator group, pressure release is slow, Patent No.:
ZL201010266670.X discloses centralized lubricating system existing pump pressure-relief valve again pipeline auxiliary pressure relief valve, solves long main oil
The problem of oil pressure release at pipeline nearly separator group.But auxiliary pressure relief valve leans on spring energy-storage, not only wastes pump station pressure, and
Operationally auxiliary pressure relief valve output end pressure only has the half of input pressure.For release, pumping plant adding pressure type has to carry
The pressure of high 2 times, this pressure is sacrificed the biggest.
Summary of the invention
The system longer in order to solve main oil pipe road in the presence of existing centralized lubricating system is pressed at nearly separator group
The problem that power release is slow, this utility model provides a kind of lubricating system with electronic relief valve, and its technical scheme is as follows:
A kind of lubricating system with electronic relief valve, including oil pump, separator group, main oil pipe road and electronic relief valve,
It is characterized in that: oil pump is connected with separator group and electronic relief valve by main oil pipe road, close in described lubricating system
Separator group is at least provided with an electronic relief valve.
Described electronic relief valve is made up of valve body, piston, screw rod and motor, wherein, is provided with barrel chamber, piston in valve body
It is arranged at into the barrel chamber and coordinates with the sealing of into the barrel chamber wall sliding, in described piston, being provided with tapped blind hole, screw rod
Being arranged in blind hole and screw rod one end other end that is connected with piston is connected with motor, described valve body is near side, main oil pipe road
Being provided with through hole, main oil pipe road is connected by described through hole with the barrel chamber arranged in valve body.
The beneficial effects of the utility model are: this utility model scientific structure design, and production and processing technology is simple and convenient, should
System all realizes off-load with motor power, assists unloader, the output of system pumping plant to be completely used for work without pump unloader and spring
Make pressure, it is not necessary to for spring energy-storage.Electric Machine at Pumping Station has inverted main Unloading Effect, and electronic unloader is attached near separator group
Part, carries out pressure at separator group assisting off-load, greatly meets the user work requirements to centralized lubricating system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Figure is numbered: 1-motor, 2-screw rod, 3-piston, 4-valve body, 5-separator group, 6-main oil pipe road, 7-oil pump.
Detailed description of the invention
Specific embodiment 1: 1 pair of this utility model is described further below in conjunction with the accompanying drawings:
The system longer in order to solve main oil pipe road in the presence of existing centralized lubricating system is pressed at nearly separator group
The problem that power release is slow, this utility model provides a kind of lubricating system with electronic relief valve, and its technical scheme is as follows:
A kind of lubricating system with electronic relief valve, including oil pump 7, separator group 5, main oil pipe road 6 and electronic pressure release
Valve, wherein oil pump 7 is connected with separator group 5 and electronic relief valve by main oil pipe road 6, at least sets in described lubricating system
Being equipped with an electronic relief valve, described electronic relief valve is made up of valve body 4, piston 3, screw rod 2 and motor 1, wherein, and valve body 4
Inside being provided with barrel chamber, piston 3 is arranged at into the barrel chamber and coordinates with the sealing of into the barrel chamber wall sliding, and piston can only be in barrel chamber inwall
Translation, it is impossible to rotate, be provided with blind hole in described piston 3, in screw rod 2 is arranged at blind hole and one end of screw rod 2 and piston 3 phase
Connecting the other end to be connected with motor 1, described valve body 4 is provided with through hole near separator group 5 side, and described through hole will divide
Oil device group 5 is connected with the barrel chamber arranged in valve body 4.
Operation principle of the present utility model and process be: when motor 1 rotates, and drives screw rod 2 to rotate, and screw rod 2 passes through screw thread
Secondary driving piston 3 translates in valve body 4, in when piston 4 travels forward, the oils and fats in compression valve body 4 flows back to main oil pipe road 6, and piston
During 3 rearward movement, oils and fats is pumped into valve body 4 from main oil pipe road 6.During the work of pumping plant fuel feeding, rotate forward, by piston 3 by controlling motor 1
Pushing valve body 4 to foremost, oil circuit volume is minimum, when guaranteeing that pipeline reaches operating pressure, after pumping plant fuel feeding end-of-job, enters
In the system release stage, Electric Machine at Pumping Station 1 inverts, and pump oil draws back pumping plant, main oil pipe road 6 release, owing to system pipeline is longer, and oils and fats
Thickness, oils and fats flow resistance is big, and the oil pressure pressure release speed at nearly separator delays the release speed of pressure near pumping plant, at this moment electricity
Dynamic pressure-relief valve motor reversal, piston retreats, and oils and fats volume increases, the nearly discharge rapidly and thoroughly of the residual pressure at separator
Falling, when concrete operations, user can determine separator group 5 and electronic relief valve according to the number of concrete lubricant housings, one
As situation next one lubricating system should be at least provided with a separator group 5 and electronic relief valve.
