How to use vacuum feeder correctly and set parameters

Release date: 2020-05-28 16:50

Why other people's feeding machine is always easy to use, my feeding machine will always block, feeding speed will be very slow. Many customers who come into contact with vacuum feeder for the first time will have this problem. If the conveying capacity of vacuum feeding can be exerted to a greater extent, there are two key points to be noted: 1. Whether the feed rate at the feed port is reasonable; 2. Whether the feeding parameters are reasonable.
Whether the feed rate at the feed port is reasonable:
Many of our projects use manual material gun to suck materials. In order to facilitate the operation, the material gun is directly inserted into the material barrel or ton bag. The material suction port of the material gun is compressed by tight materials, and the strong negative pressure will pull away the full material, which is very harmful to the feeder and easy to block the pipeline. The correct way is to form a certain air-solid mixture ratio between the material at the suction port and the air, and evenly flow into the feeding machine under the driving of the air flow. At this time, we need to design the material gun with air replenishment function. If the material overstocking time is too long, it may be very hard. At this time, we need to install an oscillator on the material gun to break the agglomerated materials.
Unreasonable loading and unloading time:
The vacuum feeding machine can not be installed in the silo, so the industry basically has time control. Then how to set the time parameter for the first time using the vacuum feeder. Whether the vacuum feeder manufacturer can give guidance, the setting of loading and unloading time is actually very simple. In the first use, set a small time first, and then add slowly according to each suction position. When reaching the material level and reaching the suction port, subtracting one second is a reasonable time. Another second is to make sure the material is discharged. There are two advantages in this way: 1. Too high material level will do great harm to the filter element. Some of our customers can use one filter element for two years, and some use it for half a year. 2. The material can be discharged every time. When the unloading valve is closed, the valve with material will not be closed. The valve with material will damage the sealing ring which operates frequently five or six times a minute.
