Abstract
The invention relates to a simple electronic control testboard, which comprises a fuel tank; a pressure operating rod for providing pressure for test fuel is arranged on the fuel tank; the fuel tank is provided with a pressure gauge and a mounting bracket used for mounting the fuel injector; and the fuel injector is connected with the fuel tank and a test fuel recovery unit through a fuel pipe. The simple electronic control testboard is characterized in that the test system also comprises an electronic control mechanism for controlling the atomization of the fuel injector. By adopting the structure, an operator can operate the pressure operating rod and a motor switch simultaneously, and observes whether the fuel injector injects fuel and the fuel atomizing condition at any time so as to determine whether the fuel injector fails. Therefore, a trouble that the fuel injector is brought to a monitoring station specially is eliminated, and the supplementary cost is reduced. The conventional fuel injector testboard is modified; the modification cost is reduced to the maximum on the premise of not wasting resources, and the simple electronic control testboard is easy to promote and use in various service stations; besides, the simple electronic control testboard can complete tests and obtain test results in short time, so the time and human resource are saved.
Description
Technical field
The invention belongs to automatically controlled supply diesel engine manufacturing technology field, particularly relate to a kind of simple electronic control fuel injector testboard.
Background technique
At present, along with the exquisiteness day by day of diesel technology, the use of common rail electric-controlled diesel engine is more and more.But the detection of electric-controlled fuel injector has become a difficult problem: detect electric-controlled fuel injector, when oil pressure reached the authorized pressure value, the solenoid valve on the oil sprayer also needed to obtain 24V (or 12V) power supply, just can open valve, and oil sprayer is sprayed fuel-oil atmozation.The tester confirms the fault point of oil sprayer according to oil sprayer whether oil spout and atomizing situation.And existing oil sprayer monitor station only can provide oil pressure, and power supply can't be provided, and when causing the oil sprayer fault, can not in time detect, thereby causes the discontented of client.
Summary of the invention
The present invention for solve the technical problem that exists in the known technology provide a kind of simple in structure, detect precise control, the reliable simple electronic control fuel injector testboard of experimental performance.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of simple electronic control fuel injector testboard, this test system comprises the fuel tank that stores test oil, the pressure operation bar that promising test oil provides pressure is installed on the fuel tank, pressure gauge is installed on the fuel tank, be used to install the mounting bracket of oil sprayer, oil sprayer connects fuel tank and test oil recovering device by oil pipe, it is characterized in that: described this test system also comprises the electrical control mechanism of control oil sprayer atomizing.
The present invention can also adopt following technical measures:
Described electrical control mechanism comprises a D.C. regulated power supply, and D.C. regulated power supply connects oil sprayer, is provided with control switch between described D.C. regulated power supply and the oil sprayer.
Described control switch is an inching switch.
Described control switch adopts optoelectronic switch.
Advantage and good effect that the present invention has are: because the present invention adopts technique scheme, promptly on original injector testing equipment, simply transform, increase the electrical control mechanism of control oil sprayer atomizing, simultaneously pressure operation bar and motor switch of operator like this, in operation simultaneously, at any time observe oil sprayer whether oil spout and fuel-oil atmozation situation, determine to judge whether oil sprayer damages.So just save the trouble of going to the monitoring station to bring specially, thereby reduced supplementary costs.The present invention is the repacking of carrying out on former oil sprayer test bench, under the situation of not wasting existing resource, reduces the repacking cost to greatest extent, is easy to promote the use of in each service station; The present invention just can finish testing experiment at short notice, see test result in addition, and then time and manpower is saved resource.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, fuel tank; 2, pressure operation bar; 3, pressure gauge; 4, oil sprayer; 5, mounting bracket; 6, test oil recovering device; 7, electrical control mechanism; 7-1, D.C. regulated power supply; 7-2, control switch; 8, oil pipe.
Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of simple electronic control fuel injector testboard, this test system comprises the fuel tank 1 that stores test oil, the pressure operation bar 2 that promising test oil provides pressure is installed on the fuel tank 1, pressure gauge 3 is installed on the fuel tank 1, be used to install the mounting bracket 5 of oil sprayer 4, oil sprayer connects fuel tank 1 and test oil recovering device 6 by oil pipe 8, this test oil recovering device adopts the comparatively general recovering device in market, main effect is that the test oil that oil sprayer sprays is recycled and reused, and said structure belongs to the main structure of known injector testing equipment; The present invention also comprises the electrical control mechanism 7 of control oil sprayer 4 atomizing, and described electrical control mechanism 7 comprises a D.C. regulated power supply 7-1, and this DC electrical source both can adopt the dryelement cell also can storage battery.D.C. regulated power supply 7-1 connects oil sprayer 4, is provided with control switch 7-2 between described D.C. regulated power supply 7-1 and the oil sprayer 4, and described control switch is inching switch or optoelectronic switch, and this example adopts inching switch.
Working principle of the present invention: at first D.C. regulated power supply is adjusted to the fuel injector magnetic system required voltage by the operator, regulate the pressure operation bar then, during value that the force value that shows when pressure gauge needs near electric-controlled fuel injector, operator's one manual operating pressure operation bar, push inching switch on the other hand, two hands are operated simultaneously, observe oil sprayer whether oil spout and fuel-oil atmozation situation then, determine to judge whether oil sprayer damages.Simultaneously pressure operation bar and motor switch of operator like this in operation simultaneously, observed oil sprayer whether oil spout and fuel-oil atmozation situation at any time, determines to judge whether oil sprayer damages.So just save the trouble of going to the monitoring station to bring specially, thereby reduced supplementary costs.
In entire test, key point is the electric time point that gets of oil sprayer: electric if the value that force value does not reach oil sprayer to be needed just allows solenoid valve get, then oil sprayer can shift to an earlier date pressure release, the fuel atomization effect variation; If force value arrives, and solenoid valve not electric, then not oil spout of oil sprayer.Both of these case all can cause can not judge correctly whether oil sprayer damages or the position of spot failure.
The present invention is the repacking of carrying out on former oil sprayer test bench, under the situation of not wasting existing resource, reduces the repacking cost to greatest extent, is easy to promote the use of in each service station; The present invention just can finish testing experiment at short notice, see test result in addition, and then time and manpower is saved resource.
