如果辽宁升降机使用的时间过长，液压系统就会有所堵塞，造成设备升降速度过慢，有的时候可能不能升降，所以定时的清理液压系统很重要，那么我们应该如何清理液压系统呢？下面为就大家详细讲述清理的方法和步骤。If the Liaoning elevator use time is too long, the hydraulic system will be blocked, resulting in equipment lifting speed is too slow, sometimes may not be able to lift, so cleaning hydraulic system timing is very important, so we should how to clean up the hydraulic system? Here are the details about the cleaning methods and procedures.
1.选择清洗油：当系统管路、油箱较干净时，可选用与工作油液相同黏度的清洗油；如系统内不干净，可选用黏度稍低的清洗油清洗。清洗油应与系统工作介质、所有密封件的材质相容。Choice of cleaning oil: when the system pipeline, the fuel tank is clean, can be used to work with the same viscosity of the oil liquid cleaning oil, such as the system is not clean, can use a slightly lower viscosity of the cleaning oil. Cleaning oil should be compatible with the working medium of the system, the material of all seals.
2.加热清洗油：热油能使系统内附着物容易游离脱落，一般需加热至50～60℃，清洗压力为0.1～0.2MPa，清洗油流量应尽可能大些，以利于带走污物。Heating oil: oil cleaning system can be easily attached material free fall, generally need to be heated to 50 to 60 DEG C, cleaning pressure is 0.1 ~ 0.2MPa, the cleaning of oil flow should be as large as possible, in order to take away the dirt.
3.安装辽宁升降机滤油器：在清洗回路中，进油口安装50～100m的粗滤油器，回油口安装10～50m的精滤油器。开始时粗滤，冲洗一段时间后逐步改用网眼细的滤油器，进行分次过滤。Installation of Liaoning elevator filter: in the cleaning circuit, the oil inlet to install 50 ~ 100m of the crude oil filter, oil return to install 10 ~ 50m of the refined oil filter. At the beginning of coarse filter, a period of time after washing and gradually replaced by oil filter mesh fine, for filtering.
4.应使液压泵间歇运转：为使清洗效果好，应使液压泵转转、停停。在清洗过程中应用木锤轻轻敲击油管数次，以促使污物尽快脱落，管路的弯曲和焊接部位要多锤击，但不可用力过猛，以防损坏油管，锤击时间占清洗时间的15％。The hydraulic pump intermittent operation: to make good cleaning effect, should make the hydraulic pump stop, stop. Application of wooden hammer tapping oil several times in the cleaning process, in order to promote as soon as possible dirt shedding, bending and welding line to hammer, but not overexert, in order to prevent damage to the tubing, hammer time cleaning time 15%.
5.确保清洗液流动为紊流状态：为了有效的清洗，清洗液流动必须成为紊流状态，即保证雷诺数在4 000以上才能确保清洗效果好；否则，清洗液应增加流量，升高温度，降低黏度。小流量室温下清洗，一般效果较差。To ensure that the cleaning fluid is turbulent flow state: for effective cleaning, cleaning fluid flow must become turbulent state, which is to ensure the Reynolds number to ensure good cleaning effect in more than 4000; otherwise, the cleaning liquid should increase the flow, temperature, viscosity reducing. Small flow at room temperature, the general effect is poor.
6.排净清洗油：清洗终了应将清洗油排除干净，包括泵、阀、管路及油冷却器内存油，可松开管路排油后并用压缩空气吹扫，或加入工作油液带走清洗油。Drain cleaning oil: end cleaning cleaning oil should be removed, including pump, valve, pipeline and oil cooler oil can loosen the line memory, drain and blow out with compressed air, or adding oil cleaning oil away.
7.辽宁升降机加入液压油：排净清洗油后，应尽快加入液压油并进行短时间试运转，以防管路锈蚀等。Liaoning elevator to join the hydraulic oil: after cleaning oil, the hydraulic oil should be added as soon as possible and carry out a short test run, in case of pipeline corrosion and so on.
