Description
Technical field
Fluid purifying apparatus detection technique field is the utility model is related to, more particularly to a kind of filter check device.
Background technology
Filter core is for removing a small amount of solid particle in liquid, can protect the normal work of equipment, is put when fluid enters
After the filter core for having certain specification strainer, its impurity is blocked, and clean stream thing is flowed out by filter core, so as to obtain extensive
Using, before filter core dispatches from the factory, it is necessary to when the performance to the filter core of same batch is tested, traditional filter check device, detection
Efficiency is low, and occurs line clogging in filter check device, and maintenance is inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of detection efficiency height, maintenance easily filter check device.
What the purpose of this utility model was realized in：Including fuel tank, fuel-displaced main pipe, oil inlet main pipe, detection device, horse
Reach, the detection device includes cylinder body, the filter core for placing cylinder interior, the inflow pipeline of cylinder body side and inflow pipeline and opposes
The flowline of side and the blow-off line of cylinder base, further include the dirt discharge groove being connected with blow-off line；The fuel-displaced main pipe
2 pipeline branches, flowline and motor are equipped with, flowline is equipped with out oil pressure P2；Oil inlet main pipe is equipped with two branches,
It is oil returning tube and inflow pipeline respectively, is respectively equipped with return pressure P3 and input pressure P1.
Compared with prior art, the beneficial effects of the utility model are：Due to inflow pipeline, flowline, oil return pipe
Every branch on road is respectively equipped with ball valve, when occurring in which that a filter core is problematic, closes corresponding ball valve, takes out filter core,
Play the role of facilitating maintenance；Due to setting multigroup filter core to detect together, the plenty of time is saved, improves filter check efficiency.
As the further preferred scheme of the utility model, inlet valve is respectively equipped with the oil inlet main pipe and fuel-displaced main pipe
And delivery valve.
As the further preferred scheme of the utility model, the blow-off line is equipped with blowdown valve.
As the further preferred scheme of the utility model, the inflow pipeline, flowline, every on oil returning tube
Branch is respectively equipped with ball valve.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Wherein, 1 fuel tank, 2 fuel-displaced main pipes, 3 oil inlet main pipes, 4 detection devices, 5 motors, 6 cylinder bodies, 7 filter cores, 8 inflow pipelines,
9 flowlines, 10 blow-off lines, 11 dirt discharge grooves, 12 go out oil pressure P2,13 return pressure P3,14 input pressure P1,15 oil inlets
Valve, 16 delivery valves, 17 blowdown valves, 18 oil returning tubes, 19 ball valves.
Embodiment
As shown in Figure 1, including fuel tank 1, fuel-displaced main pipe 2, oil inlet main pipe 3, detection device 4, motor 5, detection device 4 includes
Cylinder body 6, place cylinder body 6 inside filter core 7,6 side of cylinder body inflow pipeline 8, and 8 opposite side of inflow pipeline flowline 9,
And the blow-off line 10 of 6 bottom of cylinder body, further include the dirt discharge groove 11 being connected with blow-off line 10；Fuel-displaced main pipe 2 is equipped with 2
Pipeline branch, flowline 9 and motor 5, flowline 9 are equipped with out oil pressure P2；Oil inlet main pipe 3 is equipped with two branches, respectively
It is oil returning tube 18 and inflow pipeline 8, is respectively equipped with return pressure P3 and input pressure P1.
Inlet valve 15 and delivery valve 16 are respectively equipped with above-mentioned oil inlet main pipe 3 and fuel-displaced main pipe 2.
Above-mentioned blow-off line 10 is equipped with blowdown valve 17.
Above-mentioned inflow pipeline 8, flowline 9, every branch on oil returning tube 18 are respectively equipped with ball valve 19.
The operation principle of the utility model is described below, and oil stream flows through each branch by oil inlet main pipe 3 and fuel-displaced main pipe 2
Pipeline, into 7 filtration apparatus of filter core, with listening pin to monitor click, has worked normally, at the same observe the numerical value of return pressure P3 with
And going out the numerical value of oil pressure P2, both differences ensure 0.08 to 0.20MPa, to illustrate that the pollution discharge mechanism of filter core 7 is working properly；Prison
To survey input pressure P1 and go out the numerical value of oil pressure P2, both differences are less than or equal to 0.035MPa, that is, normal, once pressure difference is more than
0.04MPa, integrated bypass valve, that is, security system of filter core 7 are opened, need to replace maintenance immediately at this time；Directly closing pair during maintenance
The valve of pipeline is answered, conveniently directly takes out filter core 7.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed in the utility model, this
The technical staff in field is according to disclosed technology contents, it is not necessary to which performing creative labour can be special to some of which technology
Sign makes some and replaces and deform, these are replaced and deformation is within the protection scope of the present utility model.
