How to make a multi-stage centrifugal pump play a greater role

We all know that multi-stage centrifugal pumps used widely, its mouth ring is an important part of a multi-stage centrifugal pumps, multistage centrifugal how to play a greater role, you need to understand the correlation analysis multistage centrifugal pump and the role of Sandy Bay The non-self-priming vertical multi-stage centrifugal pump with a standard motor is installed. The motor shaft is directly connected to the pump shaft through the pump head. The tie rod bolts the pressure tube and the over-current component to the pump head and the inlet and outlet sections. Between pump inlets and outlets, there are many low-temperature residual heat generated during the pump production processes of petrochemical, coal chemical, and power generation companies. How to recover these low-grade heat has always been a problem. At the China International Refrigeration Exhibition held in Shanghai recently, the reporter saw at the booth of the top 500 Johnson Controls International that the TITAN-OM industrial-grade multi-stage centrifugal pump unit developed by the company can complete the recovery of industrial low-grade waste heat.
According to reports, the equipment recovers the low-grade heat discharged from chemical technology, waste heat from industrial and mining companies, and low-grade heat of surface/groundwater. It is used in high-temperature hot water at a production temperature of 90Â°C to 110Â°C, and then To the comprehensive use of thermal energy resources; in the occasions where there is a need for refrigeration, can also meet the two-tier needs of refrigeration technology and heating technology through the heat pump unit to complete the optimization of resources.
In the disposal of chemical technology, there are often both cooling and heating technologies. The traditional cooling technology and heating technology are separated by two separate systems. Many of the low-grade heat in cooling technology is discharged into the atmosphere, and the heating technology requires a lot of power. The multi-stage centrifugal pump unit independently developed by Johnson Controls, according to the customer's practical needs, tailored the unit for the project, completed the optimization of the system, and then promoted the company's energy-saving and emission reduction.
The reporter learned that multi-stage centrifugal pumps use industrial-grade multi-stage centrifugal compressors and can use a variety of driving methods to complete temperature promotion of up to 75Â°C to accustom to a variety of technical environments. Up to now, 41 sets of York industrial refrigeration equipment have been used in Shanghai Chemical Industry Park, including multi-stage centrifugal units and a variety of standard screw refrigeration units, completing energy conservation and emission reduction.
After the power supply is suddenly cut off, the horizontal multi-stage centrifugal pump and the prime mover will rotate freely, which may cause serious damage to the system. Apart from the few cases with a flywheel, pumps and prime movers usually have only a small moment of inertia. The self-balancing multi-stage centrifugal pump is designed to meet the needs of users, accelerate the development of high-pressure multi-stage pump technology, adopt the advanced technology of similar foreign products, combine the company's many years of design experience, and use the recommended hydraulic model of high-efficiency energy-saving products.
