First, the pump equipment
A pump is a machine that delivers or pressurizes a liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. The pump is mainly used to transport liquids such as water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal, as well as liquids, gas mixtures and liquids containing suspended solids.
Application field
In the chemical and petroleum sectors, raw materials, semi-finished products and finished products are mostly liquids, and the preparation of raw materials into semi-finished and finished products requires a complicated process in which the pump acts as a pressure source for transporting liquids and providing chemical reactions. In addition, in many devices, pumps are also used to regulate the temperature.
Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to use pump drainage. In the process of mineral processing, smelting and rolling, pumps are needed to supply water.
In the power sector, nuclear power plants require nuclear main pumps, secondary pumps, tertiary pumps, and thermal power plants that require a large number of boiler feed pumps, condensate pumps, circulating pumps, and ash pumps.
Selection principle
1. The type and performance of the selected pump are in accordance with the process parameters such as flow, lift, pressure, temperature, cavitation flow, and suction.
2. The characteristics of the media must be met. For pumps that transport flammable, explosive, toxic or valuable media, it is required to use shaft seals reliably or use non-leakage pumps, such as magnetic drive pumps, diaphragm pumps, and shield pumps for pumps that transport corrosive media. Corrosion-resistant materials are required for convection components. . For pumps containing solid particulate media, it is required that the convection component be made of wear-resistant material, and if necessary, the shaft seal should be flushed with a cleaning liquid.
3. High mechanical reliability, low noise and low vibration.
4. Economically, it is necessary to take into account the lowest total cost of equipment, operating, maintenance and management fees.
5. The centrifugal pump has the characteristics of high speed, small volume, light weight, high efficiency, large flow, simple structure, no pulsation of infusion, stable performance, easy operation and convenient maintenance.
