1.调试前的检查调试前必须先掌握液压系统液压泵、换向阀、溢流阀、节流阀、液压缸、马达等元件的性能、结构、控制原理及相关的技术参数,方可进行调试。(1)检查液压泵先检查液压泵与原动机连接是否牢固,再检查液压泵进、出油管安装是否正确。若进、出油管装反,可能造成液压系统无法形成压力。此外,还应检查胶管是否破损、接头是否紧固,以防从吸油管处吸入空气。液压泵初次使用时,应向液压泵内灌入液压油。
1. Pre-commissioning inspection Prior to commissioning, hydraulic system hydraulic pump, reversing valve, relief valve, throttle valve, hydraulic cylinder, motor and other components must be master of performance, structure, control principle and related technical parameters before proceeding debugging. (1) Check the hydraulic pump First check the hydraulic pump and the prime mover connection is solid, and then check the hydraulic pump into the tubing installed correctly. If into, out of the oil tube, may cause the hydraulic system can not form pressure. In addition, you should also check the hose is damaged, the connector is tight to prevent inhalation of air from the suction pipe. When the hydraulic pump is used for the first time, the hydraulic pump should be filled with hydraulic oil.
