Abstract
The invention discloses a pneumatic detection platform for an electronic injection device. The electronic injection device detection platform comprises a plurality of glass test tubes on a platform surface and a clamping device for holding and clamping an electronic injection device to be detected, wherein the lower end of each glass test tube is connected with a recovery liquid box through a check valve; the recovery liquid box is communicated with a liquid storage box through the check valve; a pipeline connected with an oil inlet pipe of the electronic injection device is inserted into a place below the liquid level of the liquid storage box; and an air inlet communicated with a pressure air source is formed at the upper part of the liquid storage box. According to the detection platform for the electronic injection device, working liquid flows under the driving of air pressure, the volume of the liquid storage box is large, and the pressure of the working liquid hardly fluctuates or keeps constant when the detection operation is conducted, so that the detection precision can be guaranteed.
Description
Technical field
The present invention relates to the monitor station of automobile electronic fuel oil jet device, particularly a kind of use air pressure drives the monitor station that detects liquid (working solution).
Background technique
Produce the automobile electronic fuel oil jet device in assembly process or after assembling finishes, need on monitor station, test, and on test stand, adjust the running parameter of EFI device.But the electrical signal of monitor station simulated automotive motor under various operating modes given tested EFI device, in order to detect and to adjust the various running parameters of EFI device.
Existing EFI device monitor station, a plurality of vertically teat glasses arranged side by side are arranged on table top, tested a plurality of EFI devices are contained in the teat glass upper end-hole respectively, there is oil pump to carry the working solution of fuel oil or similar fuel oil to tested EFI device, by the electrical signal control EFI device action of the control circuit simulated engine operating mode of monitor station, with the spray pattern of the operating frequency that detects the EFI device, fuel injection quantity, oil spout etc.Because of oil pump by pipeline directly and a plurality of EFI devices on the monitor station and connecting, during the oil spout simultaneously of a plurality of EFI devices, the oil pressure before the EFI device descends moment rapidly, in addition, if certain EFI device is arranged to be installed to such an extent that can oil pressure be descended in the jointing leakage of oil during poor sealing on monitor station.That is, monitor station its oil pressure when work can produce fluctuation.The working hydraulic pressure fluctuation of EFI device monitor station makes the work of EFI device depart from the engine operating condition of simulating, and will obviously reduce testing precision.
Summary of the invention
The present invention is intended to provide a kind of EFI device monitor station that reduces the operating oil pressure fluctuation, to guarantee testing precision.
Pneumatic-typed EFI device monitor station of the present invention, comprise a plurality of teat glasses on the table top, holding device with the tested EFI device of clamping, each teat glass lower end links to each other with recovery liquid case by one-way valve, reclaiming the liquid case is communicated with by one-way valve with liquid tank, the pipeline that links to each other with EFI device oil inlet pipe inserts under the liquid level of liquid tank, and liquid tank top has air inlet and is communicated with pressure gas source.
EFI device monitor station of the present invention has been save the necessary oil pump of existing EFI device monitor station.The working solution of EFI device of flowing through during detection enters to flow into behind the test tube and reclaims in the liquid case, enters in the liquid tank by one-way valve again, and pressurized gas can be introduced in liquid tank top, and gas pressure can drive the EFI device oil inlet pipe that working solution enters the test stand oil circuit.Owing to save hydraulic-pressure pump, the mobile of working solution is to be driven by air pressure, and the volume of liquid tank is bigger, and the minimum or constant pressure of the pressure surge of working solution can guarantee testing precision when detecting operation.
Description of drawings
The structural representation of the described monitor station of Fig. 1.
Embodiment
As Fig. 1, EFI device monitor station comprises a plurality of teat glasses 2 on the table top, holding device 9 with the tested EFI device 1 of clamping, each teat glass lower end links to each other with recovery liquid case 4 under being in table top by one-way valve 3, reclaiming liquid case 4 is communicated with by one-way valve 6 with liquid tank 5, the pipeline 9 that links to each other with EFI device oil inlet pipe 8 inserts under the liquid level of liquid tank, and liquid tank top has air inlet 7 and is communicated with pressure gas source.Gas pressure can drive working solution and enter in the EFI device oil inlet pipe 8 that is communicated with EFI device 1 in the test stand oil circuit.Pressure gas source can be bottled pressurized gas 10 as shown in Figure 1, as nitrogen bottle, helium tank, and other inert gas bottles etc., also can be air pump.As using air pump to make source of the gas, reply pressurized air is made the oil removing purified treatment.
Claims (2)
1. pneumatic-typed EFI device monitor station, comprise a plurality of teat glasses on the table top, holding device with the tested EFI device of clamping, it is characterized in that, each teat glass (2) lower end links to each other with recovery liquid case (4) by one-way valve (3), reclaim the liquid case and be communicated with by one-way valve (6) with liquid tank (5), liquid tank top has air inlet (7) and is communicated with pressure gas source under the liquid level of the pipeline insertion liquid tank that links to each other with EFI device oil inlet pipe (8).
2. pneumatic-typed EFI device monitor station according to claim 1 is characterized in that pressure gas source is nitrogen bottle (10) or air pump.
