The plastic spring lotion pump has obvious advantages in environmental protection, structural design and work efficiency, but may have some limitations in strength, temperature resistance and efficiency. When selecting lotion pumps, it should be decided whether to select plastic spring lotion pumps according to the actual use scenarios and needs.
Advantages and disadvantages of plastic spring lotion pump:
advantage
Environmental protection: the overall design of the plastic spring lotion pump takes recycling into account. The plastic spring can be recycled together with the whole lotion pump. There is no need to classify components made of different materials after disassembly, which simplifies the steps of recycling and is conducive to environmental protection.
Structural design: the plastic spring of the plastic spring lotion pump adopts the spiral structure, which can produce the maximum elastic force when the plastic spring is compressed, so that it can rebound in a short time. In addition, the two ends of the plastic spring are integrally formed with connecting parts to connect the inside and outside of the plastic spring, avoiding being sucked by the spring seat or piston rod when the plastic spring is under pressure, making it convenient for the plastic spring to exhaust quickly when it is under pressure and intake quickly when it is reset.
Working efficiency: The design of plastic spring lotion pump improves the working efficiency. For example, the spiral plastic spring has greater elasticity and faster rebound efficiency, which is conducive to the rapid return of the piston rod.
Corrosion resistance: Most plastics have strong acid and alkali resistance, which is better than the corrosion resistance of general metal materials. This is an important advantage of plastic pumps. This means that when plastic spring lotion pump is used in the environment containing acid and alkali substances, its corrosion resistance is better than that of metal lotion pump.
shortcoming
Strength issue: Early plastic pumps had the disadvantage of not being as strong as metal due to the inherent strength of plastic, but this has been resolved by using a steel lined plastic method. Therefore, if used in situations with high strength requirements, some problems may arise.
Temperature resistance: Although the temperature resistance of fluoroplastic pumps has greatly improved, it is still inferior to metal pumps. Therefore, the use of plastic spring lotion pump at high temperature may lead to deformation or even melting.
Efficiency: Although the plastic spring lotion pump performs well in some aspects, it may not be as efficient as the metal lotion pump. For example, the efficiency of fluoroplastic magnetic pumps is lower than that of ordinary centrifugal pumps.
