Questions regarding single-unit testing
Thread Content
According to the specifications, the pump must not run idle; so how should I carry out a single-unit test run? After the pump is installed, it is necessary to power it on to check whether the motor is running properly Please advise me, senior, on how to conduct a single-unit test run
It is divided into separate tests for the motor and the pump. With the separate motor test, the motor can be disconnected from the pump, allowing for testing of the motor’s rotation direction； The single-test for the pump involves connecting the motor, filling the pump and the inlet tank with liquid, starting the pump, inducing backflow, and observing the pump’s operating parameters
Just test the motor by itself – then you’ll know its direction of rotation
The motor testing requires more than 2 hours; doesn’t that mean the motor is tested only by disconnecting it from the pump?
When testing the motor alone, it is sufficient to disconnect the coupling
First, you need to figure out what it is Single-unit testing involves testing two devices separately; in the case of this device, it means testing the motor and the pump individually. First, the motor is tested by starting it to check its performance. Next is the testing of the pump. Of course, a pump won’t rotate on its own without power, so it’s necessary to connect the motor to the pump. To get the pump running, it’s essential to fill it with liquid first. Then check each parameter
