Product Description

As a professional high quality Horizontal Multistage Centrifugal Pump manufacturers, you can rest assured to buy Horizontal Multistage Centrifugal Pump from Hongzheng and we will offer you the best after-sale service and timely delivery. Horizontal multistage centrifugal pump is actually a lot of single stage pump simple series, combined together, the output water pressure can be very large. Multistage pump depends on the rotation of impeller to obtain centrifugal force, so as to transport materials. Multistage pump depends on the volume of the pump chamber to achieve suction, compression and exhaust, so it is a variable volume centrifugal pump.

The basic structure of horizontal multistage centrifugal pump is composed of water inlet section, outlet section, middle section, tail cover, impeller, pump body, pump shaft, bearing, sealing ring, packing box and other components. The impeller is the core of the pump, its speed is higher than the force, and the blade on the impeller plays the main role, the impeller should pass the static balance experiment before assembly. Impeller requirements are higher, in terms of material and design needs to meet the needs of use, reduce the wear and corrosion of impeller, prolong the service life of equipment.

The pump shell is the main body of the multistage pump, which plays the role of supporting and fixing, and is connected with the bracket for mounting bearings. The function of the pump shaft is to connect the coupling and the motor, the motor torque to the impeller, so it is the main component of the transfer of mechanical energy. Horizontal multistage centrifugal pump bearing is mainly composed of bearing body, bearing and bearing gland, bearing with grease or thin oil lubrication.

Lubrication and sealing are very important to the pump, if the choice of lubrication is incorrect or contaminated, it will affect the use of the pump, and even cause the heat of the bearing. Seal is to reduce liquid leakage, reduce waste and environmental pollution.
Horizontal multistage centrifugal pump is mainly based on the engineering needs to choose the right type of head, flow and its change law, when choosing to understand the characteristics of the multistage pump can be a good choice. What aspects should we pay attention to when choosing multistage pump?

1. The type and performance of the pump selected need to meet the requirements of device flow, head, pressure, temperature, cavitation flow, suction and other process parameters.
2, according to the transmission of the medium to choose the right kind of corrosive media need to use corrosion resistant materials; For the transmission of pumps containing solid particle medium, the convection parts are required to use wear-resistant materials, and the shaft seal is washed with clean liquid.
3, mechanical properties should also be, high reliability, low noise when running, protective measures to do enough.

4. Procurement cost is also an issue that needs to be considered. Comprehensive cost needs to be considered, and construction and operation management need to be easy.
