液压传动具有一系列的优点,故被广泛应用。但在修理时不充分了解发生故障的前后原因则很难排除。几年来,我们在液压修理中摸索出一点规律,使排除故障较快,现作如下介绍供同行参考。一般液压系统分为能源、控制和工作三个部分(见图)。修理时,首先看油池是否有油再开动油泵电机,检查电机是否正常运转。然后,打开压力表开关检查压力。如表上没有压力,应先检查溢流阀(Y 25B),把阀调节到最高压力点(即将阀按顺时
Hydraulic transmission has a series of advantages, it is widely used. However, it is hard to rule out the inadequacies of understanding the cause of failure before repairing. Over the past few years, we worked out a bit in the hydraulic repair law, so that troubleshoot faster, now for the following introduction for peer reference. General hydraulic system is divided into energy, control and work of three parts (see photo). Repair, the first oil tank to see if there is oil and then start the pump motor, check whether the normal operation of the motor. Then, open the pressure gauge switch to check the pressure. If there is no pressure on the table, you should first check the relief valve (Y 25B), the valve is adjusted to the highest pressure point (ie, the valve in time
