1. The pump is mainly used to transport liquids such as water, oil, acid and alkali, emulsion, suspension emulsion, and liquid metal. Gear oil pumps can also transport liquids, gas mixtures and liquids containing suspended solids.
2. Pumps can generally be classified into three types: positive displacement pumps, power pumps and other types of pumps according to their working principles. In addition to classification according to working principles, submersible pumps can also be classified and named by other methods. For example, according to the driving method, it can be divided into electric pumps and water turbine pumps; according to the structure, it can be divided into single-stage pumps and multi-stage pumps; according to purposes, it can be divided into boiler feedwater pumps and metering pumps; according to the nature of the liquid to be transported, it can be divided into Water pump, oil pump and mud pump, etc.
3. There is a certain interdependence between the various performance parameters of the pump, which can be represented by a curve, which is called the characteristic curve of the pump. Each pump has its own specific characteristic curve. A pump is a machine that conveys liquid or pressurizes liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy.
Commonly used water pump types include long shaft deep well pumps, electric fire pumps, diesel fire pumps, and stainless steel submersible pumps. Different pump types and specifications are selected according to different environments. It is recommended that users provide actual needs and find professional pump manufacturers to purchase. The advantage is deep wells. The performance and quality of the pump or fire pump is relatively stable, and there are professional after-sales maintenance services to solve problems such as use and failure.
