90R180DC柱塞泵中偏置活塞和偏置弹簧的作用
安装时如能将偏置活塞与偏置弹簧分开焊接以固定它们之间的距离,可有效地将泵内液体隔开或将液体从偏置活塞上卸下来,不影响泵内液体的流动 这种方法常用于高压柱塞泵的安装中然而,要使该泵达到工作压力要求,偏置活塞和偏置弹簧必须有足够的焊接质量:即要求它们间隙均匀,对密封件进行正确地检查和保养。
同时,也要求焊接后紧固牢固此外,偏置活塞与偏置弹簧之间的连接也应保持紧密、牢固否则极易产生泄漏而引起事故 在偏置活塞上装有一段油道,油从油道内通过时要在油道中留有一定的间隙,保证油道不被堵塞 当流量很小时,偏置活塞和弹簧将处于静止状态。
如果此时有较大的流量,偏置活塞就会被向后压在弹簧上并转动;反之,流量很大时,则会向后压在活塞上并转动;如果流量很大且较小时,就会向偏前移动在这一过程中偏置活塞的运动方向会发生改变当流量很小时,它仅在偏置活塞和弹簧之间移动;当流量很大时,它将移动到偏前的位置;在流量很小时不移动,这样做既是为了防止流量过大引起泵的磨损而增加工作压力从而又是为了防止油进入偏置活塞腔内被堵死在油道内而不能流出油道而使之污染。
由于液压油中往往含有杂质物质,因此要注意滤油器的作用滤油器的作用主要是对系统中存在的脏物进行过滤,它可以减少系统中污染物质的含量;滤油时不要选用过滤网;要经常更换新空气滤芯;一般滤油器上都有吸人孔;过滤元件应定期更换或及时加油。
