目前,在气缸操作动作安全问题上,提出了更高的要求。气缸在中间停止状态下,或者供给压力降低的场合,气压有变化,气缸就产生意外的动作,发生意外事故。而且气缸由无压力状态下转入工作压力状态时,会产生突然的高速运动,对人和机器将产生不利影响。为了防止这样的危险发生,保证系统的安全性,1980年制定了JIB8370“气压传动系统设计准则”,本文就确保气缸安全的系统和部件详细论述。 1.双向锁紧阀这种阀能够使气缸在行程中间停留,长期
At present, in the cylinder operation safety issues, put forward higher requirements. When the cylinder is stopped in the middle or the supply pressure is reduced, there is a change in the air pressure, which causes unexpected operation of the cylinder and an accident. And the cylinder pressure from the state into the state of work pressure, it will have a sudden high-speed movement, people and machines will have a negative impact. In order to prevent such a danger from occurring and to ensure the safety of the system, JIB8370 “Design Guide for Pneumatic Drive System” was formulated in 1980, and the system and components to ensure the safety of the cylinder are discussed in detail in this paper. 1. Two-way locking valve This valve can make the cylinder stay in the middle of the trip, long-term
