Knowledge About Plastic Lotion Pumps
Plastic lotion pump is a common industrial pump, which is mainly used to transport various liquids, especially viscous liquids, such as emulsions, cosmetics, pharmaceuticals, etc.. Its structure is very simple, consisting of several parts such as pump body, bearings and mechanical seals.
The pump body of plastic emulsion pump is usually made of polypropylene, polyacrylic acid ethyl ester, polyvinyl chloride and other materials, which have excellent performance in chemical properties, mechanical properties and stability. Compared with other materials, plastic emulsion pumps have the advantages of light weight, corrosion resistance, easy cleaning and easy maintenance. Therefore, it is widely used in food, pharmaceutical, cosmetic, printing, dye and other industries.
Plastic emulsion pumps need to pay attention to the following points when they are in use. Firstly, the pump body should be kept clean and no foreign substance should enter the pump body. Secondly, the bearings and mechanical seals should be checked regularly for wear and replaced in time. Finally, pay close attention to the working condition of the pump, if the pump is found to have abnormal phenomena, it should be stopped in time for inspection and cleaning or replacement of parts.
In conclusion, plastic emulsion pump is an important conveying equipment, which plays an irreplaceable role in practical applications. For manufacturers and maintenance workers who use plastic emulsion pumps, it is very important to be familiar with its structure and performance characteristics, and to master the correct use and maintenance techniques.
The operating principle of plastic emulsion pumps is to use the negative pressure between the pump body and the piston to pump the emulsion into the pump body and send the emulsion out through the pump head. Specifically, when the handle is pulled upward, the volume inside the pump body expands to create a negative pressure, which causes the emulsion to be drawn into the pump. When the handle is pressed downward, it is equivalent to compressing the air inside the pump body, causing the emulsion to be pushed out of the pump body. It is very important that the pump be sealed during operation, otherwise the flow of the emulsion will be affected. For this reason, plastic emulsion pumps are often equipped with O-rings around the edges of the pump body to ensure a tight seal. Also, to regulate the flow of the pump, the pump head is usually equipped with an adjustable flow valve.
