Engineering application of submersible sewage pump
The submersible sewage pump is a pump product that is connected with a pump and a motor, and works under the liquid at the same time. Compared with a general horizontal pump or a vertical sewage pump, the submersible sewage pump has obvious advantages in the following aspects: 1. Compact structure and small footprint. Since …...Read more -
Sales of submersible sewage pumps
The drainage pumps used in the building include submersible sewage pumps, submerged sewage pumps, vertical sewage pumps and horizontal sewage pumps. Since the general site in the building is small and the drainage volume is not large, the submersible sewage pump and the submerged sewage pump can be preferentially used for the drainage pump. The …...Read more -
Classification of water pumps
Pumps are classified according to their working principles: 1. Vane pump Vane pumps can be divided into: centrifugal pumps, mixed flow pumps, axial flow pumps, and vortex pumps. Centrifugal pumps can be divided into single-stage pumps and multi-stage pumps. Single-stage pumps can be divided into: single-suction pump, double-suction pump, self-priming pump, non-self-priming pump, etc. Multi-stage …...Read more -
Instructions for Deep Well Pump
1. Inspection before starting (1) Check the rotation direction of the motor. The direction of rotation of the impeller of the deep well pump is counterclockwise (opposite to the direction of rotation of the clock pointer). (2) Check the screws in each part. Check whether the screws of the water pump base are tightened, whether …...Read more -
Explosion-proof self-priming pump
The explosion-proof self-priming pump is a positive displacement pump for vacuum suction and squeeze discharge. It has some unique characteristics. Since it was invented more than sixty years ago, it has been used more and more widely in various industrial and mining situations. Working principle of explosion-proof self-priming pump ① There is an eccentric bump …...Read more -
Self-priming pump operation and maintenance
1. Introduction to the pump ZX series are horizontal, single-stage single-suction cantilever centrifugal pumps. The temperature of the working medium ranges from -80°C to +350°C, the working pressure can reach 1.6Mpa, and the head is 5 to 125m. 2. Working principle and structure description The pump adopts axial liquid return pump body structure. The pump …...Read more -
Pump type and operation manual
Type of pump ① The working principle of the centrifugal pump is: use the impeller blades to do work on the fluid, so that the pressure and kinetic energy of the fluid after passing through the impeller are increased, so the fluid can be transported to high places and far. Rotating, a vacuum is continuously …...Read more -
Self-priming non-clogging sewage pump
ZW series self-priming non-clogging sewage pump integrates self-priming and non-clogging sewage discharge. It adopts axial return and external mixing type. It can not only need to install bottom valve and irrigation water like ordinary self-priming clean water pumps, but also can suck and discharge large amounts of water. Granular solids and long-fiber impurity liquids can …...Read more -
The use of YW submersible sewage pump
The YW submerged sewage pump is suitable for installing on the bracket of the pool or sink, the motor is on the top, and the pump body is submerged under the liquid. It can be used in fixed or mobile places. The basic length of the pump is 1-3 meters, which is suitable for all …...Read more -
Why should a check valve be installed at the outlet of the pump?
The purpose of installing a check valve at the outlet of the water pump is to only allow the water pump to send water outside, and not allow the water to flow back to the pump in the opposite direction, to prevent the high pressure water from flowing back to the pump when the pump …...Read more
