What is the difference between the working principle of the spray pump head and the ordinary cosmetic pressure pump

Pump head generally includes impeller, bearing, oil ring and sealed rotating parts (including shaft). A pump generally consists of a pump body and a pump head. The pump body refers to the volute, impeller, bearing, oil shell, and seal assembly. The pump head of a centrifugal pump refers to the casing that encloses the impeller and the impeller, and also includes the drive impeller. The shaft part.
Daily chemical pump head is a machine that conveys fluid or pressurizes fluid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The pump is mainly used to transport liquids such as water, oil, acid-base liquid, emulsion, suspension emulsion and liquid metal, as well as liquid, gas mixture and liquid containing suspended solids. Pumps can usually be divided into three categories: positive displacement pumps, power pumps and other types of pumps according to their working principles. In addition to the classification according to the working principle, it can also be classified and named according to 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 the purpose, it can be divided into boiler feed water pumps and metering pumps; according to the nature of the conveying liquid, it can be divided into Water pumps, oil pumps and mud pumps, etc. According to the shaft structure, it can be divided into linear pump and traditional pump. Water pumps can only transport fluids as a medium, not solids.
Is the working principle of the spray pump head the same as the ordinary cosmetic pressure pump?
Answer: It's not the same, it's definitely not the same.
The reason is as follows: The effect of the spray pump head is that the sprayed liquid must be atomized, and the quality requirement standard of the spray pump is based on the atomization effect. The better the atomization effect, the spray pump The higher the quality standard, of course, in addition to this, there is also a problem of range. The stronger the bursting force, the longer the spray distance will be, and the stronger the spray will be. Relatively speaking, the atomization effect of the spray pump will be better. There is also the problem of spray angle. The working principle of spray pumps. Generally, spray pump manufacturers require between 30 degrees and 45 degrees, because only this angle can focus and atomize, and the sprayed liquid becomes mist and again. Strong, if the angle is too large, the atomization will appear weak and loose, the mist will become water droplets, and the mine spray pump will be too weak to drip, so that the spray will be uneven.
