Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
It is as shown in Figure 1 engine testing room oil temperature control system, including engine hanging outdoor unit cooler 2, engine sheet
Body machine cooler 5 and two-way motor-driven valve 8.The liquid outlet of engine hanging outdoor unit cooler 2 passes through hanging outdoor unit cooler liquid outlet pipe 1 and hair
9 cooling system of motivation is connected, and the inlet of engine hanging outdoor unit cooler 2 passes through hanging outdoor unit cooler input duct 3 and engine 9
Cooling system is connected, it is ensured that engine-cooling system and actual design state consistency, engine motor oil can not be by starting at this time
Machine hanging outdoor unit cooler；The water outlet of engine body machine cooler 5 is followed by engine body machine cooler outlet conduit 4 with laboratory
Ring water water inlet is connected, and the water inlet of engine body machine cooler 5 passes through engine body machine cooler water inlet line 6 and laboratory
Recirculated water water outlet is connected, and two-way motor-driven valve 8,9 main oil gallery of engine are provided on engine body machine cooler water inlet line 6
It is connected by main oil gallery oil inlet pipe 10 with the inlet of engine body machine cooler 5,9 main oil gallery of engine is returned by main oil gallery
Oil pipe line 11 is connected with the liquid return hole of engine body machine cooler 5, and the spy of main oil gallery temperature is in series on main oil gallery oil return line 11
First 7；In addition, two-way motor-driven valve 8 and main oil gallery temp probe 7 are electrically connected with rack master control system respectively.
The analog output unit (model F-FEM-ADC) of rack master control system (model AVL PUMA OPEN) with
Two-way motor-driven valve 8 (model LRQ24A-SR) communication, the temperature collecting cell (model F-FEM-AIT) of rack master control system
It is connected with main oil gallery temp probe 7 (model PT100), for acquiring the temperature signal of main oil gallery temp probe 7.Analog quantity is defeated
Unit exports 0~10V voltage signal out, and two-way motor-driven valve 8 receives 0~10V voltage signal, and corresponding 0~100% valve is opened
Stroke is spent, 0% aperture corresponds to engine body machine cooler water inlet line 6 (i.e. test chamber circulating water) and completely closes, 100% aperture
Corresponding engine body machine cooler water inlet line 6 (test chamber circulating water) fully opens；Rack master control system compares main oil gallery temperature
Degree probe 7 is calculated with after target temperature by pid, and analog output unit exports analog voltage value, and two-way motor-driven valve 8 receives
Analog voltage value simultaneously executes corresponding valve opening.
When needing high oil temperature, two-way motor-driven valve 8 closes or keeps small guide vane, at this time the heat of engine itself
Machine oil is heated rapidly.When 7 temperature of main oil gallery temp probe reaches target temperature, two-way motor-driven valve 8 adjusts valve and opens
Degree, it is ensured that oil temperature is constant.
When the actual temperature of main oil gallery temp probe 7 is lower than target oil temperature, analog output unit export 0V or
Lower analog voltage value is to two-way motor-driven valve 8, and two-way motor-driven valve 8 reaches 0% or lesser aperture, engine body at this time
