Technical field
The present invention relates to a kind of method and pick-up unit thereof that can detect to the pressure regulator valve pressure on the filter cleaner.
Background technology
At present, in the vehicle motor lubricating system, the method that the pressure of the pressure regulator valve on its filter cleaner is detected is by the full manual inspection of operating personnel, only with artificial experience, do not realize automation mechanized operation, accuracy is relatively poor, work efficiency is lower.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and a kind of pressure regulator valve pressure detection method and pick-up unit thereof of realizing automation mechanized operation, improving detection accuracy is provided.
The object of the invention realizes through following technical scheme: a kind of pressure regulator valve pressure detection method is: at first, the pressure regulator valve that need are examined is contained in the pressure regulator valve anchor clamps, and uses pressure head that pressure regulator valve is fixed through cylinder operation; Then, through oil well pump this pressure regulator valve is carried out oil-feed, and carry out fuel-displacedly from the outlet of pressure regulator valve, the pressure of oil well pump shows that through tensimeter the work of said cylinder, oil well pump and the pressure of oil well pump are by the unified regulation and control of microcomputerized control panel; When the pressure of oil well pump reaches the set pressure scope of qualified pressure regulator valve, as this pressure regulator valve for open oil-feed automatically, fuel-displaced then decidable is certified products, otherwise is judged to be unacceptable product.
The pressure regulator valve pressure-detecting device that is adopted according to described pressure regulator valve pressure detection method; It comprises frame, jig frame; In the bottom of said jig frame the pressure regulator valve anchor clamps are housed; On the top of said jig frame and above these pressure regulator valve anchor clamps, locate to be equipped with cylinder, be connected with pressure head under this cylinder; The side that being used to of said pressure regulator valve anchor clamps installed the pressure regulator valve import links to each other with fuel tank through oil inlet pipe and oil well pump, being used to of said pressure regulator valve anchor clamps a side that the pressure regulator valve outlet is installed pass through flowline and link to each other with said fuel tank; Said cylinder, oil well pump link to each other with the microcomputerized control panel respectively, on this microcomputerized control panel, the tensimeter that links to each other with oil well pump are housed.
After adopting the present invention,, realize the pressure regulator valve pressure that is contained in the pressure regulator valve anchor clamps is automatically detected, improve the accuracy that detects through of the function control of microcomputerized control panel to work such as cylinder, oil well pumps.Accuracy of detection of the present invention and sensitivity are all very high, have guaranteed the pressure regulator valve product quality, can be applicable to produce in enormous quantities line; Effectively prevented the product quality problem of former manual inspection; Reduce the labour, reduced production cost, improved work efficiency; And operation is succinct convenient, energy-saving and cost-reducing, has significant technical progress.
Description of drawings
Fig. 1 is the structural representation of pressure regulator valve pressure-detecting device of the present invention.
Embodiment
Below through accompanying drawing and embodiment the present invention is made further detailed description.
Can know that with reference to Fig. 1 pressure regulator valve pressure detection method of the present invention is: at first, the pressure regulator valve 14 that need are examined is contained in the pressure regulator valve anchor clamps 3, and uses pressure heads 5 that this pressure regulator valve is fixed through cylinder 4 work; Then; Carry out oil-feed through 7 pairs of these pressure regulator valves of oil well pump; And carrying out fuel-displaced (direction of arrow as shown in Figure 1) from the outlet of pressure regulator valve, the pressure of oil well pump shows that through tensimeter 11 work of said cylinder, oil well pump and the pressure of oil well pump are by the unified regulation and control of microcomputerized control panel; When the pressure of oil well pump reaches the set pressure scope of qualified pressure regulator valve, as this pressure regulator valve for open oil-feed automatically, fuel-displaced then decidable is certified products, otherwise is judged to be unacceptable product.
As shown in Figure 1; The pressure regulator valve pressure-detecting device that is adopted according to described pressure regulator valve pressure detection method; It comprises frame 1, jig frame 2; In the bottom of said jig frame 2 pressure regulator valve anchor clamps 3 are housed, on the top of said jig frame 2 and above these pressure regulator valve anchor clamps 3, locate to be equipped with cylinder 4, this cylinder is connected with pressure head 54 times; A side that is used to install the pressure regulator valve import of said pressure regulator valve anchor clamps 3 (being that the pressure regulator valve anchor clamps are provided with oil inlet passage 12) links to each other with fuel tank 8 through oil inlet pipe 6 and oil well pump 7, being used to of said pressure regulator valve anchor clamps 3 a side (being that the pressure regulator valve anchor clamps are provided with oil discharge passage 13) that the pressure regulator valve outlet is installed pass through flowline 9 and link to each other with said fuel tank 8; Said cylinder 4, oil well pump 7 link to each other with microcomputerized control panel 10 respectively, and the tensimeter 11 that links to each other with oil well pump 7 is housed on this microcomputerized control panel 10.
Wherein, be used to install pressure regulator valve 14 in the said pressure regulator valve anchor clamps 3, the import of this pressure regulator valve 14 down, it exports towards the right side, seals with O-ring seal 15 again; Microcomputerized control panel 10 contains microcomputer controller, and pressure regulator valve anchor clamps 3, microcomputerized control panel 10 can be placed on the frame 1.Oil well pump 7 is contained in the oil inlet pipe 6.
