General shampoo, bath gel and other care plastic packaging bottles are equipped with lotion pumps, which are widely used. Brands or buyers need to refer to many factors when choosing lotion pumps.

1. For safety, judge whether the raw materials and materials of emulsion pump are compatible. How to choose lotion pump for cleaning plastic packaging bottles?

2. Select the specification of emulsion pump according to the product use. There is a formula: recommended usage=(1-2) * pump output.

3. Select according to the capacity specification and expected use times of the product. Generally 100-300 times for one package

4. According to the specifications of emulsion pump and bottle mouth, the common caliber is 18 mm, 20 mm, 22 mm, 24 mm, 28 mm, 33 mm and 38 mm;; Common specifications are 400, 410 and 415. When selecting emulsion pump, it is necessary to ensure the sealing function of cleaning and protecting plastic packaging bottles, because this is a key factor in product storage and transportation. Lotion and asphalt are transported to the colloid mill at the same time. If the colloid mill inlet presents positive pressure, the asphalt pump adopts a positive displacement pump. If the lift of the emulsion pump is low, asphalt will enter the emulsion system. At this time, the emulsion pump is selected as a high lift pump. Lotion is a diluent of water and emulsifier. Whether it is cationic asphalt emulsifier for road emulsified asphalt or anionic asphalt emulsifier for waterproof emulsified asphalt. There is a certain degree of corrosivity. Pay attention to corrosion resistance when selecting the pump. The stainless steel gear pump relies on the small gap between the gear and the chamber to ensure the high lift of the emulsion pump. After the emulsified asphalt equipment is used, the cavity and gear are corroded by lotion, and the gear is worn (the gear is easier to be worn by water lotion). The mechanical fit gap becomes larger, and the lift of the emulsion pump becomes smaller. This is also the reason why the equipment that was able to produce high content of emulsified asphalt cannot produce such high content after one year of use.
