进口内循环潜污泵Product Description:

The utility model is characterized in that it comprises a motor cavity, a volute cavity and a cooling sleeve, the outer side of the motor cavity is provided with a cooling sleeve, the lower part of the cooling sleeve is provided with a circulating cavity, an isolating oil cavity is arranged between the circulating cavity and the motor cavity, the lower part of the circulating cavity is provided with a volute cavity, and a heat exchanger is arranged between the volute cavity and the circulating cavity. Compared with the prior art, the circulating cooling impeller with the same speed as the main shaft is used as the circulating power source of the coolant, and the heat absorbed by the coolant from the motor shell is exchanged with the sewage in the volute through the heat exchanger, which reduces the temperature of the coolant and repeatedly circulates to achieve the thermal balance of the motor; The double end face mechanical seal is designed in the isolation oil chamber to form a three-way seal together with the single end face mechanical seal in the volute chamber, which overcomes the influence of the low viscosity of the coolant and effectively prevents the coolant water from evaporating into the motor chamber and forming water condensation in the motor wiring chamber.

进口内循环潜污泵characteristic:

The internal circulation cooling submersible sewage pump is a kind of pump product which is connected with the motor and can work dry or submerged at the same time. Compared with the general horizontal pump or vertical sewage pump, this kind of pump obviously has the following advantages: compact structure and small floor area. The sewage pump can be directly installed in the sewage tank because it works under the water. There is no need to build a special pump room to install pumps and machines, which can save a lot of land and infrastructure costs; Easy installation and maintenance. Small sewage pumps can be installed freely. Large sewage pumps are generally equipped with automatic coupling devices for automatic installation, which is quite convenient for installation and maintenance; Long continuous operation time. Because the pump and motor are coaxial, the shaft is short, and the rotating parts are light, the load on the bearing is relatively small, and the service life of the sewage pump is much longer than that of the general pump; Low vibration noise, low motor temperature rise, no pollution to the environment.

进口内循环潜污泵Principle:

The circulating cavity is provided with a circulating cooling impeller, which is located on the motor shaft, and a conical sleeve is arranged between the circulating cooling impeller and the motor shaft.
