Described power supply 2 is 12V power supplys, by main power switch 18, controls on/off.
The utility model can be tested two cover Motorized vacuum pump assemblies simultaneously.The working method of this system is: 1) controller for vacuum pump 4 is controlled vacuum pump 5 work according to the degree of vacuum of vacuum tank 6 and (when vacuum tank 6 low vacuums are during in a certain pressure, opened the motor of vacuum pump 5.When vacuum tank 6 degree of vacuum are during higher than a certain pressure, close the motor of vacuum pump 5, this mode can be verified control strategy and the Motorized vacuum pump performance that vacuum pump producer provides); 2) utilize the time relay 7 to control vacuum pump 5 work (set time relay 7 is opened and the shut-in time, and this mode can arrange the control strategy of vacuum pump 5 flexibly, research vacuum pump 5 performance under various conditions).Two kinds of working methods are except the on off control source difference of vacuum pump 5, and other links are all the same.Vacuum-pressure signal, air flow sensor 14 that vacuum sensor 12 gathers vacuum tank 6 gather the flux signal that flows out air by automatically controlled throttle valve 11 gas circuits; The control system that data collection and control card 16 is sent to upper PC 17 by these signals shows and preserves.The control system of upper PC 17 is by selecting the aperture of the automatically controlled throttle valve of electric automobile work condition curve controlled, can make vacuum pump 5 be operated under various simulated condition conditions, thus working state and the performance of check electric vacuum pump 5 under electric vehicle real vehicle runnability.
The test principle of this system: this system has almost contained the routine test content of all electric vacuum pumps, the test of the Motorized vacuum pump assembly providing by Dui Yuan producer, can obtain the performance such as electric vacuum pump control strategy, pressure initiation time, maximum vacuum, operating current of former producer.When the electric vacuum pump of tape controller is not tested, thereby formulate control strategy by upper PC control system, by gathering vacuum sensor signal, carry out the unlatching of setup times relay and close electric vacuum pump is controlled.The operating conditions that upper PC control system can arrange electric vacuum pump is vacuum release rate, on simulation real vehicle under different operating modes, thereby the impact that for example under abrupt slope, the serious crowded road conditions in city, urban conditions and expressway operating mode, driver driving person causes the vacuum flow of Motorized vacuum system the use of brake petal under vehicle.Thereby whether the performances such as the response time of check electric vacuum pump, vacuum pumping speed meet the requirement of electric motor car.
The function of the upper PC control system of this system: by upper PC control system can Real Time Observation electric vacuum pump degree of vacuum, the parameter such as vaccum pump motor electric current, vacuum flow changes.By control system, vacuum pump control strategy can be set: the time controls and pressure controling mode (time control mode: when control system detects degree of vacuum and is less than a certain pressure, utilize the time relay to control the operating time that vacuum pump work is set.Pressure controling mode: when control system detects degree of vacuum and is less than a certain pressure, utilize the time relay to control vacuum pump work and stop after degree of vacuum reaches setting value).Upper PC control system can arrange vacuum pump operating conditions, by operating mode, select (abrupt slope, the serious crowded road conditions in city, urban conditions and expressway operating mode under vehicle) to call corresponding vacuum line flow-time graph, by air flow sensor signal, carry out the aperture of the automatically controlled throttle valve of closed loop control, reach the object of simulation actual conditions.This control system, except above function, also has test parameters and preserves, the function that report generates automatically.
This electric vacuum pump comprehensive performance test system is except carrying out the traditional performance test of electric vacuum pump, increase again the performance matching test ability of the electric vehicle of Liao Yuwo company production, by the simulation of electric vacuum pump system vacuum flow is reached to the simulation of car brakeing to degree of vacuum demand, although the error analysis of this Work condition analogue there is no definite conclusion, but there is directive significance for electric vacuum pump and mating of electric motor car, the invention of this test stand is except shortening the pilot development cycle of electric vacuum pump, also obviously shortened the type selecting time of electric motor car to electric vacuum pump, exploitation for electric vehicle is significant.
Can by adding real electric parking brake system device, replace the dry run environment of electric vacuum pump, but do like this, will obviously increase the cost of pilot system.
