Manual and automatic secondary loop of sewage pump: one for use and one for standby.

The manual and automatic secondary circuit diagram of sewage pump is as follows, one for use and one for standby:

The circuit diagram refers to the diagram used to represent the state of the transaction process. Here, the process of a transaction is represented by a circuit, because the final point contained in the circuit diagram is also the target point of transaction completion.

Extended data sewage pump is a kind of pump product which is connected with motor and works under liquid at the same time. Compared with ordinary horizontal or vertical sewage pump, the sewage pump has compact structure and small floor space. Convenient installation and maintenance, large sewage pumps are generally equipped with automatic coupling devices for automatic installation, which is quite convenient for installation and maintenance. Long continuous working hours.

Because the pump is coaxial with the motor, the shaft is short, the rotating parts are light, the load (radial direction) on the bearing is relatively small, and its life is much longer than that of ordinary pumps. There are no cavitation damage and irrigation diversion problems. Especially the latter point brings great convenience to the operator. Low vibration noise, low motor temperature rise and no pollution to the environment.
