Working Principle Of Plastic Lotion Pump

The liquid distributor (liquid distributor) is a component that uniformly supplies the multi-pass evaporator. There are three types of liquid distributors: centrifugal type, Yijing type, and Venturi type. Most of our country uses the Yijing type.

There are many specifications for liquid distributors because the number of channels, the diameter of the inlet and outlet pipes, and the length of the outlet pipe is different. According to different specifications, the capacity of the liquid distributor is also different. The flow rate of each specification has an upper limit and a lower limit. If the flow exceeds the upper limit, the pressure of the liquid distributor and the liquid distributor will drop too much. If the flow rate is lower than the lower limit, the pressure distribution is not uniform, so when choosing a liquid distributor, you must consider the load range, the number of channels, the length of the spray pipe, the evaporation temperature, and each channel. Each pair of air outlets has a quantitative piston and a control piston. Take the mainline or mainline II as an example. After one mainline is charged, the other mainline is in a state of pressure relief, and only the leaks related to the charged mainline will discharge oil. Therefore, each work cycle includes two work processes.

The working principle of Plastic Lotion Pump :

1. When the lubrication is stopped, the two pistons, the quantitative piston, and the control piston are at the lower end. When mainline I am charged, mainline II will be removed and the control piston will move up first. Then the quantitative piston moves upward. In this way, the lubricant discharged by the quantitative piston will control the groove in the piston and be discharged from the upper air outlet. The lubricant discharged when controlling the movement of the working piston can enter the main road II, which was in the state of being unloaded in China at that time.

2. During work 2, mainline II is charged, and mainline I am unloaded. Therefore, first, control the piston movement, and then control the quantitative piston movement. The lubricant is discharged when the quantitative piston moves are discharged through the air outlet below. The pressure from the air outlet to the lubrication point is equal to the pump output pressure minus the pressure loss through the main road and the pressure loss through the distributor. In order to control the piston to obtain sufficient thrust, the pressure difference between the two main roads must be above 50bar.
