Single-stage double-suction fire pump set

The housing of the diesel engine fire pump constitutes the working chamber of the pump. The impeller, shaft and rolling bearing are the rotors of the pump. Suspension bearing parts The supporting parts support the rotor parts of the pump, and the rolling bearings are subjected to the radial and axial forces of the pump. In order to balance the axial force of the diesel engine fire pump, most pumps have sealing rings at the front and rear of the impeller, and a balance hole on the back cover of the impeller. Because some pumps have little axial force, there is no seal on the back of the impeller. ring and balance hole. The axial sealing ring of the diesel engine fire pump is composed of packing gland, packing ring and packing to prevent air intake or large water leakage.

The QXB submersible centrifugal aerator adopts the direct drive of the motor and the impeller, and uses the centrifugal force generated by the rotation of the impeller to displace the surrounding water to form a low-pressure area to inhale the water flow. At the same time, a vacuum is created at the inlet of the impeller to inhale air. The water is fully mixed to form a uniform gas-water mixture, which is quickly discharged under the action of centrifugal force.
Due to the extremely strong water jet, the effective water circulation is caused, and the air is sheared into a large number of tiny air bubbles. The surface area is greatly improved, and because the bubbles rise slowly, a large amount of oxygen in the air is dissolved in the water, which makes the power efficiency of the machine better than other types of aerators.
