Background technique
Bypass valve opening pressure in engine oil filter filter element part is that one of cleaner product performance is important
Index.When external temperature is reduced to a certain particular value or when oil filter is beyond the normal use time limit, by-passing valve can be in spy
Different pressure effect is lower to open, and filtered machine oil is allowed to flow directly into engine.However one, impurity in machine oil can be into
Enter engine, but compared with there is no machine oil in engine and caused by lose for, it is much smaller.Therefore by-passing valve is urgent
In the case of protect engine key.But do not reach regulation service life when filter paper, and bypass valve opening pressure it is low when, largely
Unfiltered machine oil will enter engine, to cause engine scuffing；When filter paper reaches regulation service life, and by-passing valve
When cracking pressure is high, it will cause the oil level deficiencies for being supplied to engine washing, to cause the abrasion of engine.
Based on above-mentioned, have the following problems when in use: present oil filter seat accessory by-passing valve is when in use
It is required to pressure value when by-passing valve is opened under detection part time job state, and the part after by-passing valve opening process and unlatching is let out
Dew amount size is difficult to detect, and later period part assembly is easy to the low accident of engine oil pressure occur.
Summary of the invention
The purpose of the present invention is to provide a kind of bypass valve opening pressure and amount of leakage check test platforms, to solve above-mentioned back
The problem of being proposed in scape technology.
To achieve the above object, the invention provides the following technical scheme: a kind of bypass valve opening pressure and amount of leakage are examined
Testing stand, including pedestal, oil return box, check-out console, fixing seat, sleeve column, controller, supporting table, pressure sensor and fluid flow
Sensor；An oil return box is fixedly installed on the inside of the pedestal；A check-out console is fixedly installed at the top of the pedestal；
A fixing seat is fixedly installed at the top of the check-out console；The top rear of the check-out console is also fixedly connected with a support
Platform；The side insertion of the supporting table is equipped with a cylinder, and the bottom of this cylinder is fixedly connected with a sleeve column；It is described
The top of supporting table is also fixedly installed with a controller.
Further, the bottom inside of the sleeve column is provided with a circular trough, and the inside fixation of this circular trough is set
It is equipped with a pressure sensor.
Further, the inside insertion of the fixing seat is equipped with the oil return pipe being connected with oil return box, and oil return
A liquid flow sensor is fixedly installed on the inside of pipe.
Compared with prior art, the invention has the following beneficial effects:
At the top of the fixing seat that first part handstand is placed on check-out console when inspection, then it will be pushed at the top of part by cylinder
Sleeve column, which compresses, to be sealed, by machine oil injection sleeve column inside after fixing, when the engine oil pressure in injection sleeve column bottom circular slot is up to greatly
By-passing valve is opened when part spring force, and pressure value when pressure sensor record is opened, machine oil passes through out of part after unlatching
After reveal, liquid flow sensor in the fixing seat of lower end in oil return pipe records machine oil amount of leakage, and whole process repeats to detect, most
It takes cracking pressure and amount of leakage average value for detection final detection result eventually, can accurately detect every by-passing valve part time job
State valve opening and in the process oil leakage amount avoid later period part assembly from the low accident of engine oil pressure occur and occur.
