挖掘机配件选择合适的液压滤清器七点注意

日期:2022-07-18   来源:http://www.dybocheng.com
挖掘机配件液压过滤器是输送介质管道上不可缺少的系统,通常安装在减压阀、泄压阀、固定水位阀或其他机械设备的进口端,以去除介质中的杂质。这里小编认为挖掘机配件选择合适的液压滤清器七点注意。
Excavator accessories hydraulic filter is an indispensable system on the transmission medium pipeline. It is usually installed at the inlet of pressure reducing valve, pressure relief valve, fixed water level valve or other mechanical equipment to remove impurities in the medium. Here, Xiaobian believes that there are seven points to pay attention to when choosing the appropriate hydraulic filter for excavator accessories.
1、进出口管径:一般情况下,过滤器的进出口贸易管径不应低于配套泵的进口管径,一般与进口管径相同。
1. Inlet and outlet pipe diameter: generally, the inlet and outlet pipe diameter of the filter should not be lower than the inlet pipe diameter of the supporting pump, which is generally the same as the inlet pipe diameter.
2、公称压力:根据过滤器管路可能产生的压力确定过滤器的压力等级。
2. Nominal pressure: determine the pressure grade of the filter according to the pressure that may be generated by the filter pipeline.
3、孔数的选择:关键军事需要阻隔的杂质颗粒大小根据介质步骤的加工要求确定。各种规格型号的金属丝网可以阻挡的颗粒大小,可以参考相关数据表。
3. Selection of the number of holes: the particle size of impurities that need to be blocked in the key military is determined according to the processing requirements of the medium steps. The particle size that can be blocked by wire mesh of various specifications and models can be referred to the relevant data sheet.

4、过滤器材质:过滤器的材质一般与与其连接的处理管道材质相同。对于管道的服务标准,可以选择铸铁、碳钢、低合金钢或不锈钢材质的过滤器。
4. Filter material: the material of the filter is generally the same as that of the processing pipe connected to it. For the service standard of the pipeline, the filter made of cast iron, carbon steel, low alloy steel or stainless steel can be selected.
5、过滤器阻力损失的计算:一般情况下,水过滤器的工作压力损失在额定流量下为0.52~1.2kpa。
5. Calculation of filter resistance loss: generally, the working pressure loss of water filter is 0.52 ~ 1.2kpa under rated flow.
6、确定适用范围,并不是精度越高的液压过滤器越好。精度越高,价格越贵,但在大多数情况下,我们可以使用一些中等精度的液压过滤器来解决问题,不会造成不必要的浪费。
6. To determine the scope of application, the hydraulic filter with higher accuracy is not the better. The higher the precision is, the more expensive the price is. But in most cases, we can use some medium precision hydraulic filters to solve the problem, which will not cause unnecessary waste.
7、加长臂挖掘机厂家建议可以先确认安装位置、管道安装位置、使用的液压过滤器类型,大致可分为压力油过滤、回油过滤、吸油过滤、洗油过滤、旁通过滤五种。
7. The manufacturer of the lengthening arm excavator suggests that the installation position, pipeline installation position and the type of hydraulic filter used can be confirmed first, which can be roughly divided into five types: pressure oil filtration, return oil filtration, oil suction filtration, washing oil filtration and bypass filtration.
总之,液压滤清器是挖掘机配件的关键部分,那么我们在选择液压滤清器的时候,一般来说就要注意以上七点,更多内容就来网站http://www.dybocheng.com咨询了解吧!
In a word, hydraulic filter is the key part of excavator accessories. When choosing hydraulic filter, we should generally pay attention to the above seven points. For more information, please visit the website http://www.dybocheng.com Consult and understand!
