Description
Technical field
The utility model relates to electrical part pick-up unit, especially relates to the pick-up unit for electromagnetism by-pass valve.
Background technology
Electromagnetism by-pass valve is generally also called " blowdown valve ".It is arranged in the draft tube near air throttle, and it is the pressure relief device of most of turbosupercharged engine first wife when dispatching from the factory.Because turbine is that the strength utilizing waste gas to discharge drives, when receiving throttle (during as shifted gears, bringing to a halt) in driving procedure, closed throttle.Turbo blade (compressor impeller) still continues to rotate under inertia effect.Now because of the Trimmed sums blade of air throttle continuation supercharging caused by, in air inlet pipeline, the air pressure of (between air throttle and turbine) can improve rapidly.In order to protect pressure charging system, after pressure reaches a certain limit value, air inlet by-pass valve is opened, the air of surplus (pressure) is led back to between filter cleaner and turbine, realize the function of step-down protection, as can be seen here, electromagnetism by-pass valve serves considerable effect to the life-span of automobile and normal operation, the detection means of electromagnetism by-pass valve is also very single at present, the not special pick-up unit for electromagnetism by-pass valve, and be all that detection person manually detects one by one, expend time in, and testing result untrue, due to the quality problems of electromagnetism by-pass valve, often there is following problem in automobile: 1, if electromagnetism by-pass valve is stuck can cause supercharger over-pressurization at valve-closed position, engine outputting power when high capacity operates is excessive, infringement can be produced to engine, if 2 electromagnetism by-pass valve are stuck in open site, supercharger lost efficacy, the i.e. electromagnetism by-pass valve not return of exhaust-driven turbo-charger exhaust-gas turbo charger, the exhausted air quantity promoting turbine is caused to reduce, cause the rotating speed of compressor impeller to decline and cause the fault of engine charge quantity not sufficient and over-emitting black exhaust, engine power loss is large, and showing as steps on the gas can not add speed.
Utility model content
The utility model, for the defect of the pick-up unit of electromagnetism by-pass valve in prior art, provides that a kind of detection efficiency is high, easy to operate, working stability, testing result are accurate and visual, can the electromagnetism by-pass valve pick-up unit that simultaneously detects of hyperchannel.
The technical scheme that the utility model technical solution problem adopts is: electromagnetism by-pass valve pick-up unit, comprise gas pressure stabilizing mechanism, signal processing mechanism and the pressure input be arranged on electromagnetism by-pass valve, pressure detection end, electric plug connector, the filtering pressure reducing valve that described gas pressure stabilizing mechanism comprises pressure transducer and connects successively, pressure regulator valve, gas-holder and by-pass valve control, filtering pressure reducing valve connects external gas source, by-pass valve control Bonding pressure input end, described signal processing mechanism comprises central processing unit and connects the detected pressures signal input part of central processing unit respectively, pulse signal output end, display touch input screen, printer, power supply, described pressure transducer is arranged on pressure detection end and connects detected pressures signal input part, described pulse signal output end is connected with electric plug connector.
The beneficial effects of the utility model: compared to existing technology, 1, after external gas source, connect gas pressure stabilizing mechanism source of the gas is stablized, can ensure to detect the true and reliable of data; 2, do not need manually manually to detect one by one too much, can detect by hyperchannel simultaneously, improve detection efficiency, save cost of labor; 3, testing process is simple to operation, without the need to too many operation after installing, coordinates display and printing equipment, makes testing process more directly perceived.

Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, in conjunction with embodiment, the utility model is described in further detail with reference to the accompanying drawings below.
In fig. 1 and 2, described electromagnetism by-pass valve pick-up unit, comprise gas pressure stabilizing mechanism, signal processing mechanism and be arranged on pressure input a on electromagnetism by-pass valve, pressure detection end b, electric plug connector d and dead end c, described gas pressure stabilizing mechanism comprises pressure transducer 5 and the filtering pressure reducing valve 1 connected successively, pressure regulator valve 2, gas-holder 3, by-pass valve control 4, filtering pressure reducing valve connects external gas source, by-pass valve control Bonding pressure input end, pressure input is connected with the electric plug connector on electromagnetism side valve.
As shown in Figure 3, described signal processing mechanism comprises central processing unit and connects the detected pressures signal input part of central processing unit, pulse signal output end, display touch input screen, printer, power supply respectively, pressure transducer is arranged on pressure detection end and connects detected pressures signal input part, and electric plug connector is connected with pulse signal output end.
Whether the function that the utility model is mainly used in shown electromagnetism by-pass valve meets design requirement, after external gas source reduces pressure by gas pressure stabilizing mechanism after filtration, again through pressure regulator valve pressure regulation, make bleed pressure be stabilized in a certain pressure value P a, and provide output interface to connect with the pressure input a mouth of electromagnetism by-pass valve.Pressure because of external gas source generally fluctuates comparatively large, and Pa can be made to meet test request after pressure stabilizing mechanism decompression, pressure regulation.PWM (high-frequency impulse) signal (in prior art, pulse signal generator can realize) of the exportable variable duty ratio of signal processing mechanism pulse signal output end, and provide interface to connect with the electric plug connector d of electromagnetism by-pass valve.After signal processing mechanism often exports the signal of a PWM, gather the pressure value P b of pressure detection end b immediately.When dutycycle is from 0% to 100% change, Pb is then from Pa to 0 change.Signal processing mechanism take dutycycle as horizontal ordinate, shows dutycycle-Pb curve on a display screen and print by printer with Pb value for ordinate.According to dutycycle-Pb curve, testing staff can judge whether electromagnetism by-pass valve meets the requirements, this structure of the detecting device is simple, and working stability, testing result is accurate and visual.Testing process is simple to operation, and device can detect multiple by-pass valve after expansion simultaneously, thus improves detection efficiency.This device can be used as the standard detecting devices of by-pass valve manufacturer and user.
