Causes and Solutions for Damage to Imported Silicone Tubing in Peristaltic Pumps
As a consumable in peristaltic pumps, silicone tubing may encounter various types of damage during use. Under normal conditions, with a pump speed of 100 rpm and transporting liquids at room temperature, the lifespan of silicone tubing can range from 200 to 400 hours. However, imported A-60-F pump tubing can...
What Is the Working Principle of a Construction Hoist Roller?
A Construction Hoist Roller—also known as a guide roller or mast roller—is a key mechanical component used in rack-and-pinion construction hoists (building elevators). Its primary function is to ensure smooth, stable, and aligned movement of the hoist cage along the mast section during vertical travel.
