2019-06-28 16:28:44 How to improve the tightness of tubular screw conveyor?　　 Tubular screw loading conveyor has the advantages of low manufacturing cost, strong sealing, strong stability, simple operation, long service life, etc. It can be installed with more points in the middle without moving the driving device. But in use, due to various reasons, the sealing performance will decrease. What should we do to improve its sealing performance at this time? The following editor will take you to take a look at the following methods shared by mechanical technicians. How to improve the sealing performance of tubular screw loading conveyor: 　　 Method 1: Lubricate the contact surface between the shaft and the packing of the pipe screw conveyor and the packing itself through the oil cup to enhance the lubrication and wetting effect, and reduce the wear of the packing and the shaft At the same time, an oil film layer is formed to prevent the powder from flowing out through the gap at the journal. The oil groove extends to the inner layer, and the sealing effect is obvious.　　 Method 2: Lengthen the shaft sleeve ruler at the end seat sealing packing 　　 extend the size of the shaft sleeve at the end seat sealing packing of the tubular screw loading conveyor, so as to increase the number of packing turns and enhance the sealing effect. Method 3: Design a pair of labyrinth skeleton seal rings inside the end seat bushing. Design a pair of labyrinth skeleton seal rings inside the end seat bushing. One is fixed on the end seat bushing and the other is installed on the shaft to run with the shaft to prevent The material powder flows out and plays a role of sealing. The above is the specific method to improve the tightness of the screw conveyor shared by the editor. If you have other doubts, you can consult online customer service or call for consultation, and we will help you solve the sealing of the tubular screw conveyor together. Sexual issues.
