Its product structure mainly includes silo, proportioning system, weighing system, control system and other parts. The working principle of the proportioning machine is mainly to achieve automatic control and measurement through computer control system and sensors.

[0003] The use of proportioning machine is very wide. It can accurately measure and mix raw materials of different components to meet the accurate requirements of different components in the production process. According to different proportioning methods and use environment, proportioning machine can be divided into gravity proportioning machine, pneumatic proportioning machine, flow proportioning machine and weighing proportioning machine. In addition, there are special equipment specifically used for liquid proportioning, such as liquid proportioning machine, which can mix two or more different liquids in a certain proportion. Proportioning machine is an important industrial production equipment, widely used in chemical, building materials, metallurgy, petroleum, food, medicine and other fields.

[0004] The existing proportioning machines used in car washes have piston rings that are easily worn out by sand and scale during long-term use, causing the piston rings to get stuck on the inner wall of the equipment. This may cause the proportioning machine to become blocked and produce a sound of sticking, so staff are required to replace the piston rings regularly.
