Good hydraulic oil is very helpful for the use of filter press

The hydraulic system of the filter press plays a very important role in the whole system, and the selection of hydraulic oil has a great impact on the filter press. Hydraulic oil can provide strong pressure for the filter press. If you want the filter press to operate normally, you need strong pressure. When selecting hydraulic oil, consider various factors and choose a neutral hydraulic oil with anti-wear and pressure resistance.

The hydraulic system of the filter press has a hydraulic station dedicated to pumping and storing oil. The storage space of the hydraulic station is also very limited, so it is necessary to add appropriate hydraulic oil to the hydraulic station regularly. Under normal circumstances, this amount can be about 85%, because as the oil temperature rises, the volume becomes larger, and the excessive oil will directly affect the normal operation of the hydraulic station. The amount of oil in the hydraulic station shall not be less than 40%, because too little oil will affect the convulsion of the internal pump. Therefore, in daily life, it is necessary to regularly inspect and maintain the hydraulic station.

Method of using oil filter repair agent of filter press filter: we need to clean the groove and leak new filter plate surface. Secondly, the black-and-white repairing agent of oil surface repairing agent was prepared in the ratio of 1:1. Then, apply it to the groove, fill the groove and slightly higher than the surface of the filter plate; Spread out the groove, quickly cover the filter cloth, and squeeze the filter plates together to make the repair agent and the filter cloth viscous. While squeezing the groove together, the glue naturally forms and does not change, and can be used normally. Filter plate and filter cloth are in direct and near direct contact with the filtrate in filter production, so their loss is much greater than that of other components! Relatively speaking, the price of filter cloth is relatively low, and it is relatively easy to repair, but the filter plate is different. For every manufacturer, the repair of filter plate is a troublesome problem. However, the successful development of oil surface repairing agent solves the problem that the filter plate is difficult to repair, and saves us a lot of money and materials.

1. Willem filter cloth

The chemical name of vinylon filter cloth is polyvinyl alcohol. Its strength is lower than that of polyester, and its elasticity is poor. The fabric maintains its shape, and its durability is 1-2 times that of cotton. But one of the big features is that it can withstand the action of strong alkali, and has good moisture absorption and easy to combine with rubber. It is a good material used in rubber industry. Its disadvantage is that it has low temperature resistance and the temperature reaches 100 ℃. It has contractility and is not acid resistant. Application: for manufacturers with strong alkalinity and rubber industry.

2. Polyester filter cloth

Polyester staple fiber filter material performance: acid resistance, weak alkali. Polyester filter cloth has good recyclability and poor conductivity. The temperature resistance of polyester fiber is generally 130-150 ° C. This product has the special advantages of ordinary felt filter cloth and has a good high cost performance. It is commonly used in felt filter materials. varieties. Filtration performance: polyester short fiber filter cloth has short raw material structure, dense fabric, good particle retention, but poor stripping and permeability. Water leakage is not as good as polyester long fiber filter cloth. Uses: pharmaceutical, sugar, food, chemical, metallurgical, industrial filter press, centrifuge, etc.

3. Nylon filter cloth

Nylon fiber has high strength, and nylon strength is medium strong. According to measurement, nylon fiber is 10 times that of cotton fiber and 50 times that of rubber. Nylon fiber is resistant to strong alkali and weak acid. However, nylon is not light resistant and is prone to discoloration and embrittlement. Therefore, nylon fabrics should not be exposed to the sun for a long time.
