What is a liquid dispenser? What is the working process?

What is a liquid dispenser? It is used to distribute various liquids to different workshops. Including liquid dispensers, washing machines, dishwashers, car wash dispensers, etc. Because each application is different, the flow rate and working principle of the liquid distributor are also different.


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 use Yijing type.


There are many specifications of liquid distributors, because the number of channels, the diameter of the inlet and outlet pipes, and the length of the outlet pipe are 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 main line or main line II as an example. After one main line is charged, the other main line is in a state of pressure relief, and only the leaks related to the charged main line will discharge oil. Therefore, each work cycle includes two work processes.





So, let us analyze how it works? There are two aspects.
The first working process is when the lubrication stops, the two pistons, the quantitative piston and the control piston are at the lower end. When the main line I is charged, the main line 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.


The second work process is that in work process 2, the main line II is charged and the main line I is unloaded. Therefore, first control the movement of the piston, and then control the movement of the quantitative piston. The lubricant discharged when the quantitative piston moves is 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.
