Description
Technical field
The utility model relates to Engine Block Test FIELD OF THE INVENTIONThe, cold temperature control apparatus in especially a kind of motor.
Background technique
At present, supercharged engine is after supercharging, and intake temperature raises, and in order to reduce intake temperature, can install intercooler that is air-cooled or water-cooled on the engine, with the intake temperature after cooling of charge.When engine test, due to the condition in laboratory limit, the polytrope of engine model and the equal factor of test objective, be difficult to the intake temperature after directly using automobile-used engine intercooler to control supercharged engine supercharging.Therefore, doing engine test, or during test engine, need a kind of in the control gear of cold temperature, control the intake temperature of motor.
In engine test field, in motors all both at home and abroad, the method for the intake temperature of cold control supercharged engine is all use heat exchanger to reach control intake temperature by controlled cooling model rate-of flow or temperature.But this method has following problem: one, control accuracy is low, this is because the specific heat of cooling medium (water) is large, the change of its flow or temperature is larger on the temperature impact of gas after cooling; Two, the pressure loss is large, this is because gas is all by heat exchanger, and the impact of heated exchanger accuracy of manufacturing, the pressure loss of gas may be larger; Three, speed of response is slow, and prior art controlled cooling model medium carrys out the gas temperature after controlled cooling model, and its response time is long, and speed of response is slow.
In view of the foregoing, in existing motor, cold temperature control apparatus needs to improve.
Model utility content
The purpose of this utility model is to overcome deficiency of the prior art, cold temperature control apparatus in a kind of motor is provided, by improving the control accuracy of supercharged engine intake temperature, meeting harsher engine test requirement, improving the technical merit of engine test.
The utility model to achieve these goals, adopt following technological scheme: cold temperature control apparatus in a kind of motor, be by: air inlet pipeline, heat exchanger, cooled-air line, condensate water discharging ball valve, three-way control valve, temperature transducer, pressure transducer, butterfly valve, rising pipe, water outlet ball valve, inlet pipeline, filter, water intake ball valve, engine charge pipeline are formed; Between pressurized machine and motor, three-way control valve is set, between pressurized machine and three-way control valve, air inlet pipeline is set, engine charge pipeline is set between motor and three-way control valve, described engine charge pipeline sets gradually temperature transducer, pressure transducer, butterfly valve along airintake direction, between the suction port of heat exchanger and air inlet pipeline, bypass duct is set, between the gas outlet of heat exchanger and three-way control valve, cooled-air line is set.
Described cools down water feed-water end arranges inlet pipeline, and cooling water waterexit end sets out water lines, and inlet pipeline sets gradually water intake ball valve, filter along water (flow) direction, rising pipe sets out water polo valve.
Described heat exchanger gas outlet arranges condensate water discharging ball valve.
The beneficial effects of the utility model are: the hot gas that pressurized machine is discharged enters air inlet pipeline, part hot gas enters three-way control valve by air inlet pipeline, another part hot gas enters heat exchanger by bypass duct, three-way control valve is entered through cooled-air line after cooling in heat exchanger, three-way control valve makes cold and hot gas mix, then enter engine charge pipeline, mixed gas by temperature transducer, pressure transducer, butterfly valve, finally enters motor successively; According to the mixed gas temperature data that temperature transducer detects, three-way control valve is regulated to make the temperature data of mixed gas control in the temperature values of setting, according to the mixture pressure data that pressure transducer detects, butterfly valve is finely tuned and makes the pressure data of mixed gas control in the range of pressure values of setting.The cooling procedure that hot gas in bypass duct enters heat exchanger is, cooling water enters inlet pipeline, pass through water intake ball valve successively, filter enters heat exchanger, water intake ball valve is for regulating the flow of inlet water of cooling water, impurity in metre filter cooling water, avoid blocking inlet pipeline and heat exchanger, cooling water and hot gas carry out heat exchange in heat exchanger, hot gas temperature is reduced, cooling water carries out displacement to the heat in hot gas makes own temperature raise, cooling water after heat exchange enters rising pipe, by discharging after water outlet ball valve, water outlet ball valve is for regulating the water flow of cooling water, regulate water intake ball valve and water outlet ball valve to control the cooling water flow entered in heat exchanger simultaneously, thus control the chilling temperature of hot gas, in heat exchanging process, hot gas forms condensed water by thermal change is cold, and condensed water enters the outlet of heat exchanger gas and discharges through condensate water discharging ball valve.
Temperature transducer and three-way control valve current collector control unit control, first by setting temperature value range input electrical equipment control assembly, surveyed mixed gas temperature data is transferred to electrical equipment control assembly by temperature transducer, when mixed gas temperature value is higher than setting temperature value range, electrical equipment control assembly controls the flow that three-way control valve increase comes from the cooled gas of cooled-air line automatically, or reduce the flow coming from the hot gas of air inlet pipeline, make the temperature value of mixed gas be reduced in setting temperature value range; When mixed gas temperature value is lower than setting temperature value range, electrical equipment control assembly automatically controls three-way control valve and reduces the flow coming from the cooled gas of cooled-air line, or increase the flow coming from the hot gas of air inlet pipeline, the temperature value of mixed gas is increased in setting temperature value range.
Set temperature sensor and pressure transducer on engine charge pipeline, effect is suction pressure and the intake temperature of measuring and feed back motor.Engine charge pipeline is provided with butterfly valve, and effect is finely tuned the suction pressure of motor.Inlet pipeline arranges filter, and the impurity in cooling water is filtered in effect, avoids blocking heat-exchanger and pipeline; Simplicity of design, compact structure, cost is low, and energy consumption is low; Efficiently, practical, non-maintaining, reduce rate of fault, save human cost.
