提到过滤器厂，我们就会想到那些层出不穷的过滤器，一般情况下过滤器按照不同的作用分类可分为很多种。其中一种常见的就是吸油过滤器，该过滤器设在泵的吸入管路上，滤除油箱内的残留污染物质的通过空气孔进入的污染物，起到保护泵的作用。但是为了避免泵产生空穴现象的发生，必须充分注意压力损失，过滤器厂在生产每一种过滤器产品的时候都已经充分的赋予这些产品自身与众不同特点。

 

Speaking of filter factories, we will think of those filters that emerge endlessly. Generally, filters can be classified into many kinds according to their different functions. One of the common ones is the oil suction filter, which is located in the suction pipeline of the pump. It filters the pollutants from the residual pollutants in the tank through the air holes to protect the pump. However, in order to avoid the occurrence of pump cavitation, full attention must be paid to pressure loss. When producing each filter product, the filter factory has fully endowed these products with their own unique characteristics.

 

 

 

还有以下几种常见的过滤器在生活中是比较常见的，列如高压管路过滤器——通常是设在泵的出口管道上，有保护污染物不进入系统的作用。因此可以控制系统的污染物浓度。但是因为是高压主管路，因此要受泵的脉动和压力冲击，强度要慎重考虑，所以过滤元件的材质。

 

There are also several common filters in life, such as high-pressure pipeline filters, which are usually located in the outlet pipeline of the pump, to protect pollutants from entering the system. Therefore, the concentration of pollutants can be controlled. However, because it is a high-pressure main circuit, it should be subject to pump pulsation and pressure impact, the strength should be carefully considered, so the material of filter elements.

 

 

 

还有一种是回流过滤器——通常情况下是设在系统的回油管路上，虽是低压管路，但根据传动装置的运转状况，也会出现脉动或压力冲击，所以对元件材质、强度要充分考虑。进口泵。其作用是把系统内产生或侵入的污染物在返回油箱前捕获到。因此它是控制系统污染浓度的有效重要的过滤器。

 

There is also a reflux filter - usually located in the system's oil return pipeline, although it is a low-pressure pipeline, but according to the operation of the transmission device, there will be pulsation or pressure impact, so the material and strength of components should be fully considered. Import pump. Its function is to capture pollutants generated or intruded into the system before returning to the tank. Therefore, it is an effective and important filter for controlling pollution concentration.

 

 

 

循环过滤器——设在油箱循环的回油路上，即使系统不在工作也可以把油箱内污染物捕集到，系统的容量大。所以在要求要求严格的清洁度时往往被采用，因此，降低污染浓度的效率好。另外安装着冷却器，具有可以同时进行冷却、容易维修等优点。但需要用专用泵和电机，造价高。

 

Circulation filter - set on the return road of the tank cycle, even if the system is not working, the contaminants in the tank can be trapped, and the capacity of the system is large. Therefore, it is often used when strict cleanliness is required, so the efficiency of reducing pollution concentration is good. In addition, a cooler is installed, which has the advantages of simultaneous cooling and easy maintenance. But special pumps and motors are needed, and the cost is high.

 

 

 

之后值得一提的就是，也是平常需要注意的事几个事项。安装滤油器在液压系统中的安装位置一般情况下要装在泵的吸油口处，目的是滤去较大的杂质微粒，以保护液压泵的作用。泵的吸油路上一般都安装有表面型滤油器，一般情况下压力损失小于0.02MPa左右为宜。还可以安装在泵的出口油路上，由此看来此处安装滤油器的目的是用来滤除可能侵入阀类等元件的污染物的作用的，可见过滤器厂为生产这些净化设备可谓是用心良苦。

 

After that, it is worth mentioning that it is also a few things that need to be paid attention to. The installation position of the oil filter in the hydraulic system is usually installed at the oil suction port of the pump. The purpose is to filter out the larger impurity particles to protect the function of the hydraulic pump. Surface oil filters are usually installed on the suction path of pumps. In general, pressure loss is less than 0.02 MPa. It can also be installed on the outlet oil road of the pump, so it seems that the purpose of installing the oil filter here is to filter out the pollutants that may invade the components such as valves. It can be seen that the filter factory is conscientious in producing these purification equipment.
