Hainan water pump
Feed pump is a kind of mechanical equipment used to supply water from one place to another. It is widely used in industry, civil use and agriculture. For those who need to buy a feed water pump, it is very important to know some basic knowledge before buying.
First, choose the type of feed water pump according to the use place and purpose.
First of all, we need to consider the place and purpose of purchasing the feed water pump. According to different working principles, feed water pumps can be divided into centrifugal pumps, self-priming pumps and piston pumps. Centrifugal pump is suitable for conveying clean water, sewage, chemical solution and other media; Self-priming pump is suitable for self-priming transportation of low viscosity media such as water, sewage and oil; Piston pump is suitable for high viscosity media and media with certain particles. According to their respective characteristics, selecting the appropriate pump type can improve the efficiency of pump use and reduce the failure rate of equipment.
Second, the correct choice of feed pump head and flow.
Secondly, it is necessary to select the lift and flow of the feed water pump according to the actual needs. Lift is the energy required for the pump to transport water from a lower place to a higher place, usually in meters and water. Flow refers to the amount of water passing through the feed water pump per unit time, usually in cubic meters per hour. When purchasing a feed pump, the head and flow of the pump should be determined according to the actual working conditions to ensure that the working capacity of the feed pump meets the requirements.
Third, pay attention to the corrosion resistance of feed water pump
Corrosion resistance is an important selection index. Some feed pumps are used to transport chemically aggressive media. In this case, it is necessary to choose a pump made of materials with strong corrosion resistance. Commonly used materials with corrosion resistance are stainless steel, polyester, polypropylene and so on. When selecting the material of the pump, we should choose the appropriate material according to the nature of the medium to ensure the normal operation of the pump.
