Vertical multistage centrifugal pump, Vertical multistage centrifugal pump
The vertical multistage centrifugal pump is one of the centrifugal pumps, and the pump adopts a vertical and sectional form in the structure. The vertical multistage centrifugal pump is safe, stable, long in life, small in floor space, and convenient in maintenance and repair.Roots
Vacuum Pump Used In Vacuum Furnace

The vertical multi-stage centrifugal pump adopts an excellent hydraulic model with high efficiency and energy saving, so it has the advantages of high efficiency and wide performance range, and better meets the user's use requirements. The vertical multi-stage centrifugal pump is suitable for industrial and urban water supply and drainage, high-rise building pressurization, long-distance water supply, heating, bathroom, boiler cold and warm water cycle pressurization, air conditioning and refrigeration system water supply and equipment support.Roots Vacuum

The vertical multi-stage centrifugal pump is composed of two parts: the motor and the pump. The motor is a Y-type three-phase asynchronous motor. The pump and the motor are connected by a coupling, and the whole is a rigid connection, and no correction is needed when used. The pump consists of a stator part and a rotor part. The stator part of the pump is composed of the inlet section, the middle section, the guide vane, the outlet section, and the stuffing body. In order to prevent the stator from being worn, the stator is equipped with a sealing ring, a balance sleeve, etc., and can be replaced with spare parts after wear. The rotor portion is composed of a shaft, an impeller, a balance hub, and the like. The lower end of the rotor is a water-lubricated bearing, and the upper part is an angular contact ball bearing. The axial force of the DL-type vertical multi-stage centrifugal pump is mostly carried by the balance drum, and the remaining small part of the residual axial force angular contact with the ball bearing is tolerated. The water inlet section and the outlet section and the joint surface are sealed by a paper pad. The shaft seal is made of packing or mechanical seal and can be selected by the user.Vacuum
Pump For Refining Edible Oil

The working principle of the vertical multistage centrifugal pump is to convert the mechanical energy of the prime mover into the kinetic energy of the liquid. The centrifugal pump relies on the action of the rotary impeller on the liquid to transfer the mechanical energy of the prime mover to the liquid. Due to the action of the centrifugal pump, the velocity energy and the pressure energy are increased during the flow from the impeller inlet to the outlet. The liquid discharged by the impeller is pressed out. Most of the chamber's speed can be converted into pressure energy and then sent out along the discharge line. At this time, the toilet at the inlet of the impeller forms a vacuum or a low pressure due to the discharge of the liquid, and the liquid in the suction pool is pressed into the impeller inlet under the action of the liquid surface pressure. Thus, the rotating impeller continuously draws in and discharges the liquid.roots
