The working principle of the liquid bag filter is to filter by pressure. A complete set Bag filter it consists of three parts: liquid bag filter stainless steel container, internal support basket and liquid filter bag.

The filtered liquid is injected from the top or side of the bag filter to directly enter the liquid filter bag, so that the liquid filter bag can be evenly distributed, and there is no negative effect of turbulence; all the fine particles filtered by the bag filter are intercepted In the liquid filter bag, it is easy to replace.

Liquid bag filters include single bag filters, multi-bag filters; or are divided into side-entry bag filters, top-entry bag filters, and small bag filters.

In the hot summer, many equipment also need high-temperature protection, such as the bag filter that has received much attention. In order to avoid unnecessary problems with the equipment, high-temperature protection is required in summer. Don’t be sloppy. This is very important for bag filters. important.

1. Anti-high temperature of hydraulic system of bag filter

   Regarding the hydraulic system, whether it is a single-bag filter or a multi-bag filter, this system is a more critical part of the equipment. Because of its frequent work, the frequency of extension or retraction may be tens of thousands; because of the hydraulic system. It bears the great pressure of the equipment on the filter plate of the filter press, and the pressure on the filter plate can often reach tens of MPa. As the hydraulic oil in the hydraulic system, it is the part with higher endurance and often needs Bear a pressure of tens of megapascals. In this case, the temperature of the hydraulic oil will be relatively high under normal conditions. In addition to the high temperature in summer, in these two cases, it can be said that it is adding fuel to the fire, so that the hydraulic oil will be the temperature It is very easy to exceed the working limit, so it is easy to cause the hydraulic oil to evaporate.

   

   Because when the temperature of the hydraulic oil of the bag filter is high, it is easy to evaporate and reduce the hydraulic oil. This makes the oil volume less stable. The volume of the hydraulic oil of the equipment will vary with the pressure. Change and change, so it is usually very easy to make the pressure of machinery and equipment difficult to meet the pressure requirements during normal operation.

2. Second, the bag filter filter plate to avoid high temperature

   Under the influence of the sun and high temperature, the filter plate of the filter press is irradiated by the sun and the oxidation is accelerated. Especially the filter plate on the bag filter, the filter plate of some bag filter equipment is made of polypropylene plastic material, that is to say, plastic material, so when exposed to the sun, it will cause oxygen molecules in the air With the change of the raw materials of the filter plate, the plastic filter plate oxidizes and deteriorates, and becomes hard and brittle. Under such conditions, the filter plate of the filter press is very easy to be damaged, which will lead to an increase in the cost of equipment use.

   Therefore, when the bag filter is used in the summer when the weather is hot, attention should be paid to controlling the heat reduction and prevention of the bag filter to ensure the normal operation of machinery and equipment.

   I believe that users do not want to have problems with the bag filter they bought, so users must do a good job of high temperature protection of the bag filter in the hot summer. If you have other questions in this regard, you can call for consultation and the customer service will Will answer you the relevant knowledge about the bag filter.
