液压机循环冲洗泵站的组建的两种方案
发布者:admin  日期:2017-06-08  点击:1135
液压机循环冲洗泵站的组建通常有2种选择方案。
一是离线冲洗即建立独立于液压系统以外的临时冲洗泵站,进油用粗过滤器,回油用精过滤器,原因是回油压力较低而且脉动不大。其优点是冲洗泵站独立于液压系统之外,对设备自身的安全不会产生影响,另外还可以在冲洗设备上添加加热器提高冲洗效果。
二是利用液压系统自身的工作泵站作为冲洗泵站,包括利用本泵过滤器,含随机带来的滤芯加热器等设备,通常称之为在线冲洗。它可以节省大量的设备和劳力成本,适用于管道少的小型液压系统,但要充分考虑液压设备自身的技术参数,确保系统设备的自身安全,施工技术要求较高。
对冲洗方案的选择原则是,在保证安全的原则下首先考虑用本泵冲洗,在本泵冲洗能够达到冲洗所需要的流量和压力的情况下,可采用本泵冲洗,否则就要采用离线冲洗。
武钢液压站各试验台系统本泵能够提供的最大流量,经过与冲洗系统所计算的最小流量进行比较可知油缸马达试验台,油泵试验台和液压阀试验台的液压管道必须采用离线冲洗的方式,而伺服阀试验台和大流量伺服阀试验台则采用本泵冲洗就能完成冲洗要求。

There are usually 2 options for the establishment of a circulating irrigation pump station.
First, the off-line flushing is to establish a temporary flushing pump station outside the hydraulic system, and a coarse filter for oil inlet and a fine filter for oil return. The reason is that the oil return pressure is low and the pulsation is not large. The utility model has the advantages that the flushing pump station is independent of the hydraulic system, and has no influence on the safety of the equipment itself, besides, the heater can be added to the flushing device to improve the flushing effect.
Two is the use of the hydraulic system itself, the pump station as a flushing pump station, including the use of the pump filter, including random filter, heater and other equipment, often referred to as online irrigation. It can save a lot of equipment and labor costs for small hydraulic system in the pipeline is less, but to fully consider the technical parameters of its hydraulic equipment, ensure the equipment safety system, the construction of higher technical requirements.
The choice principle of flushing plan is to ensure the safety of the principle of first consideration flush with the pump, the pump in flushing can achieve the required flow rate and flushing pressure, the pump can be used to wash, otherwise you will use offline flushing.
The maximum flow test system of the hydraulic pump can provide Wuhan station, after comparing the cylinder motor test bench and minimum flow flushing system to calculate the hydraulic pipeline pump test and hydraulic valve test rig must be used offline flushing mode, and the servo valve test bench and large flow servo valve test bench is used this pump can finish washing washing requirements.
