With the progress of the industrialization and automation level,the equipment needs to support a large number of high performance and high reliability belt weigh scale pneumatic and sealing components.Even the system actuation valve malfunction and not action,accumulator both cushioning effect,is the basic requirements to determine the quality of the products,but also the basic requirements of products to the market before,of course,no special wrench products and experimental scale of belt weigh scale.

A large number of machinery and equipment to meet the needs of their development.This requires that the equipment itself should have good self-protection system,there is not high quality factor among the currently manufactured parts.Easy to manipulate and control the computer,easy to implement crushing process automation.The spring friction clutch,clutch friction belt weigh scale or set the safety pin and so on.The break itself up to the limit,to intercept the power transmission and prevent machine damage.

Can thrust plate right when overloaded.During normal operation,the belt weigh scale thrust plate cylinder pressure acting on the cylinder below the belt weigh scale thrust action valve in the upper limit position,the thrust plate no moving belt weigh scale development of safe and reliable protection device replaces the traditional passive means of protection,maximum guarantee for continuous operation of the machine safely and smoothly is particularly necessary.So that the device can operate safely,the failure rate remained at a low level.
