Technical Field
The invention relates to the technical field of pump equipment, in particular to skid-mounted equipment for recovering raw materials of pump equipment.
Background
A pump is a machine that delivers or pressurizes a fluid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, causing the liquid energy to increase. The pump is mainly used for conveying liquid such as water, oil, acid-base liquid, emulsion, suspension emulsion and liquid metal, and can also be used for conveying liquid, gas mixture and liquid containing suspended solid. Pumps can be generally classified by their operating principle into three types, positive displacement pumps, dynamic pumps and other types of pumps. In addition to classification by theory of operation, classification and naming may be by other methods. For example, the driving method may be classified into an electric pump, a turbine pump, and the like; can be divided into a single-stage pump and a multi-stage pump according to the structure; can be divided into a boiler feed pump, a metering pump and the like according to the application; the liquid can be divided into a water pump, an oil pump, a slurry pump and the like according to the property of the transported liquid. According to the structure with or without shaft, the linear pump and the traditional pump can be divided.
