Abstract
The utility model relates to an oil pump safety valve unlatching characteristic detecting apparatus and belongs to the technical field of automobile engine oil pump performance detection. The oil pump safety valve unlatching characteristic detecting apparatus comprises a sealing compactor, a workpiece positioning seat, a testing air storage tank, a high-pressure air storage tank, a pressure cylinder flow sensor, and a pressure sensor. The sealing compactor is installed on the workpiece positioning seat. The testing air storage tank, the high-pressure air storage tank, and a pressure cylinder are disposed at one side of the workpiece positioning seat. The sealing compactor is communicated with the testing air storage tank through a communicating pipe A. Hydraulic oil is replaced by compressed air used as a measuring medium in the oil pump safety valve unlatching characteristic detecting apparatus. Therefore, the cleanliness of a detected product is enhanced and equipment power consumption is reduced. The oil pump safety valve unlatching characteristic detecting apparatus resolves a problem of large power consumption, easily-caused pollution on the cleanliness of the product, and no benefit for energy saving and environmental protection of a conventional oil pump safety valve detecting method and is especially suitable for detecting the unlatching characteristic of the oil pump safety valve.
Description
Technical field
The utility model relates to a kind of oil pump relief valve opening feature pick-up unit, belongs to automobile engine oil pump Performance Detection technical field.
Background technology
The automobile engine oil pump safety valve is the important safety parts in automobile engine system, in order effectively to guarantee the reliability of product, must carry out performance test to engine motor oil pump relief valve opening feature, both need by enough pressure detection its open and close point pressure value and leakage rate.Traditional Performance Detection mode adopts to be measured the mode of measured workpiece high pressure liquid force feed, easily the cleanliness of product is polluted, and has also improved equipment power dissipation, is unfavorable for energy-conserving and environment-protective.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, energy-conserving and environment-protective, cleaning, the testing process equipment power dissipation is little, detection and judged result precision are high, large to solve traditional Performance Detection mode power consumption, and easily the cleanliness of product polluted, be unfavorable for the oil pump relief valve opening feature pick-up unit of energy-conserving and environment-protective problem.
The utility model is realized above-mentioned purpose by following technical proposals:
a kind of oil pump relief valve opening feature pick-up unit, it is by the sealing compactor, the workpiece positioning seat, the test gas-holder, high pressure tank, pressurized cylinder, solenoid valve, retaining valve, flow sensor, pressure transducer consists of, it is characterized in that: the sealing compactor is housed on the workpiece positioning seat, workpiece positioning seat one side is provided with the test gas-holder, high pressure tank and pressurized cylinder, the sealing compactor is communicated with by communicating pipe A with testing between gas-holder, be communicated with by communicating pipe B and communicating pipe C respectively between test gas-holder and high pressure tank and pressurized cylinder, on described communicating pipe A, pressure transducer is installed successively, flow sensor and solenoid valve, on communicating pipe B, retaining valve is installed.
The utility model has the advantage of:
1, use pressurized air replacement liquid force feed as measuring media, promoted the cleanliness of test product.
2, use pressurized air replacement liquid force feed as measuring media, cancelled the Hydraulic Station of traditional oils survey performance platform, reduced equipment power dissipation.
Description of drawings
Accompanying drawing is the structural representation of this utility model.
In figure: 1, sealing compactor, 2, the workpiece positioning seat, 3, the test gas-holder, 4, high pressure tank, 5, pressurized cylinder, 6, solenoid valve, 7, retaining valve, 8, flow sensor, 9, pressure transducer, 10, communicating pipe A, 11, communicating pipe B, 12, communicating pipe C, 13, detected workpiece.
Embodiment
This oil pump relief valve opening feature pick-up unit is made of sealing compactor 1, workpiece positioning seat 2, test gas-holder 3, high pressure tank 4, pressurized cylinder 5, solenoid valve 6, retaining valve 7, flow sensor 8, pressure transducer 9.Sealing compactor 1 is housed on workpiece positioning seat 2, workpiece positioning seat 2 one sides are provided with test gas-holder 3, high pressure tank 4 and pressurized cylinder 5, sealing compactor 2 is communicated with by communicating pipe A10 with testing between gas-holder 3, be communicated with by communicating pipe B11 and communicating pipe C12 respectively between test gas-holder 3 and high pressure tank 4 and pressurized cylinder 5, pressure transducer 9, flow sensor 8 and solenoid valve 6 are installed on communicating pipe A10 successively, retaining valve 7(are installed referring to accompanying drawing on communicating pipe B11).
During this oil pump relief valve opening feature pick-up unit work, at first will be detected workpiece 13 puts on workpiece positioning seat 2, then will be detected workpiece 13 with the sealing compactor compresses, when the pressure of test in gas-holder 3 during lower than testing setup pressure, carry out tonifying Qi by high pressure tank 4 to test gas-holder 3, simultaneously by pressurized cylinder 5 superchargings, so that the pressure in test gas-holder 3 reaches testing setup pressure.
When the pressure in test gas-holder 3 reached testing setup pressure, solenoid valve 6 was opened, and detected workpiece 1 is ventilated, until the pressurized air in test gas-holder 3 is emptying, solenoid valve 6 cuts out.In this course of work, the safety valve of detected workpiece 13 can open and close according to performance curve, this change procedure of detected workpiece 13 is by pressure transducer 9 and flow sensor 8 records, and draw out the performance curve that detected workpiece 13 opens and closes, to judge whether product is qualified, detect thereby complete the safety valve opening feature that is detected workpiece 13.
