Z6625单轨移动式抛砂机(图1)是靠液压驱动大、小臂作回转运动,用抛头将型砂抛实的一种铸工造型设备。全机由坐椅、抛头、小臂、大臂、车架、刮砂、液压系统、电气等八个部分组成,抛头最大与最小作用半径分别为6.6米、2.82米,大臂回转半径为4米,转角为180°,小臂回转半径为2.6米,转角为270°,抛砂量每小时为25立方米。根据工作的需要,整个机器可左右移动,由传动箱通过链轮驱动车轮,行走在单轨上。它在装配和使用过程中,经常出现一些故障,如何从这些故障现象中分
Z6625 single-rail mobile sand throwing machine (Fig. 1) is a caster modeling equipment that uses hydraulic pressure to drive the big and small arms to make rotary motions. The whole machine is composed of eight parts: chair, throwing head, small arm, big arm, frame, sand scraping, hydraulic system, and electrical. The maximum and minimum action radius of the throwing head is 6.6 meters and 2.82 meters respectively. It is 4 meters with a 180 degree corner. The arm has a slewing radius of 2.6 meters. The angle of rotation is 270 degrees. The amount of sand thrown is 25 cubic meters per hour. According to the needs of the work, the entire machine can move left and right. The gear box drives the wheels through the sprocket wheel and travels on the monorail. During the process of assembly and use, it often appears some failures. How to distinguish these failure phenomena?
