Method for replacing piston seal of servomotor of hydraulic hoist
The invention relates to the field of servomotor equipment, in particular to a method for replacing a hydraulic hoist servomotor piston seal, which comprises the following steps of: separating a servomotor piston rod from a gate on a dam body, and withdrawing the piston rod to the highest position by utilizing a hydraulic system; hydraulic oil in the servomotor is discharged, and a lifting appliance is installed so that a piston rod of the servomotor can move downwards subsequently; a servomotor piston rod is lowered, and a servomotor lower end cover is dismantled; and sealing and replacing the piston of the servomotor, and inspecting the replaced piston of the servomotor. According to the method for replacing the piston seal of the hydraulic hoist servomotor, the piston of the servomotor is convenient to replace, and time and labor cost are reduced.
本发明涉及接力器设备领域，具体涉及一种更换液压启闭机接力器活塞密封的方法，所述更换液压启闭机接力器活塞密封的方法，包括：将接力器活塞杆与坝体上的闸门脱离，且利用液压系统将活塞杆收回至最高位置；将接力器中的液压油进行排出，并安装吊具以便后续接力器活塞杆向下移动；下放接力器活塞杆，拆除接力器下端盖；接力器活塞密封更换，并对接力器更换后的活塞进行检验。本发明的更换液压启闭机接力器活塞密封的方法，便于更换接力器活塞，降低时间和人工成本。
