Belt sway switch is used to detect the conveyor belt’s off-tracking amount of the belt conveyor. It is a safety protection device that can automatically alarm and stop the machine when the conveyor belt is off-tracking. It plays an important role for the belt conveyor machine. With this, how should we distinguish the quality of the belt sway switch? EXCT will explain for you in the following article: The belt sway switch is consist of three parts: the roller, serial verb construction and the electrical switch. However, there are three main reasons which affect the quality of the belt sway switch.
1.The Roller is also called the vertical rod and responsible manufacturer generally adopts the stainless steel pipe and good quality bearings to manufacture it. However, in the market there are still a few small brand manufacturers who adopt iron pipe and poor quality bearing, even more exaggerated some of them didn't adopt bearings. Since the roller is the key part and rolling all the time, they will break down in less than one month if adopt poor quality rollers in the outside, the quality difference is very big and discoverable.
2. The internal electrical switch is also the key to judge the quality of belt sway switch, good manufacturers adopt switches parts in Omron or Bluebird, the cost is about 30-45 yuan, small brands adopt cheap switch which cost is about 5 yuan, the difference is large. This doesn't show up on the outside. You don't know the difference until you use it.
3.The sealing of belt sway switch is also the key to judge the product quality. Because belt sway switch is used in the open air for a long time, the temperature difference between day and night is large, so the sealing of the product is quite important. If the sealing is not good, the service life of electrical switch is greatly shortened in the case of high temperature and high humidity.
