1, Oil pump
An oil pump is a device specifically designed for transporting lubricating oil and fuel. Its main working principle is to rely on a certain force to transport liquid from a low-pressure area to a high-pressure area. Oil pumps can be divided into two types based on their working principles: mechanical oil pumps and electronically controlled oil pumps. Mechanical oil pumps require mechanical transmission during operation, while electronically controlled oil pumps can achieve variable frequency or fixed frequency operation based on changes in control signals.
2, Lotion pump
Lotion pump is a kind of equipment specially used to transport lotion, cosmetics and other mixtures. The working principle of the lotion pump is to transport the mixture from the low-pressure area to the high-pressure area by centrifugal force. During the emulsification process, oil and water are mixed evenly to achieve a certain proportion and distribution pattern between the liquid and solid phases of the mixture. Lotion pump is usually made of stainless steel, which is widely used in food, cosmetics and other industries.
3, Foam pump
Foam pump is a kind of equipment specially used for foam fire extinguishing system. In the process of extinguishing the fire, the foam pump mixes compressed air and water to form a foam liquid, and then sprays the foam liquid onto the fire source to form a protective foam layer to achieve the effect of extinguishing the fire. The working principle of foam pump is to inject water and air into the foam mixing chamber, and then push out the foam liquid through compression.
To sum up, oil pump, lotion pump and foam pump are all fluid conveying equipment, but their application occasions and working principles are different. The oil pump is mainly used to transport lubricating oil and fuel oil, the lotion pump is used to transport lotion and other mixtures, and the foam pump is mainly used in the foam fire extinguishing system. During use, it is also necessary to choose the appropriate pump category and model according to different usage scenarios and work requirements.
