Hangzhou Zweig Electronic professional equipment automotive engine cooling water pump integrated performance test system

Instrument Name: Automobile engine cooling water pump integrated performance test system instruments Model: VG-313 features: The system is designed for the engine pump performance testing and life testing, mainly flow, head, shaft power (torque) and the efficiency of the test. First, the test equipment to meet the following requirements: 1, the entire test bed for the closed structure, comprising pressure sensors, temperature sensors, torque, speed sensors, differential pressure sensors, flow sensors, valves, heaters, water tanks and piping and other components . 2, the device must meet the tank volume flow (0-330L / min) pump test requirements with moisturizing facilities, the interface can be connected to Party A cooling water system, heated from 25 ℃ to 85 ℃ not more than 60 minutes. 3. Set the desired temperature by the test computer, heater and heat exchanger automatic temperature control to the set temperature. 4, the entire test device is automatic data acquisition and control systems, the computer handles the measured data and plotted test curve, either automatically or by manual operation of the test stand control. 5, the driving speed is not less than the maximum pump 7200r / min, accuracy ± 0.5%, in the range of 500-7200r / min between, may be stabilized at any desired speed. 6, the maximum flow test equipment pipeline system to meet 0-300L / min flow rate, the flow sensor accuracy ≤ ± 0.5%. 7, test equipment pump inlet pressure measurement range: -0.1 ~ 0.1Mpa, the pump outlet pressure measuring range: 0 ~ 0.2Mpa, pressure measurement accuracy: ± 0.5%. Torque measurement range: 0 ~ 20Nm, accuracy no less than ± 1.0% II pilot project conducted a test system, performance test: a test pump station at a certain temperature, flow rate at different speed, the outlet pressure, lift shaft power, torque and pump efficiency and to draw a graph of head, shaft power, pump efficiency, torque and traffic between. Do cavitation test record. 2. Reliability test (fatigue test) (three stations) can set up automatic fatigue tests. The device can automatically control loop from A to B loop, and then from B to A circulation loop is repeated 100 hours of operation.
