hydac filter is generally used in the hydraulic system or oil filter inside the filter, its role is to filter the impurities inside the hydraulic oil, to ensure the clean hydraulic oil and the smooth operation of the hydraulic system. So what kind of material is better when choosing stainless steel oil filter?
Stainless steel oil filter sometimes filters the medium is not ordinary hydraulic oil, it will have certain corrosiveness or high working temperature. Therefore, glass fiber can not be used. Stainless steel metal mesh should be used, and the fiberglass material is relatively brittle. The filter material is not reusable after the filter element is clogged. It should be replaced in time. If it is made of stainless steel, it can be reused.
The filter materials used in the general Heideke filter are all high-quality glass fiber. Because the glass fiber is relatively sharp, it can break the oil spore well, can filter the impurities in the oil better, and the precision of the glass fiber is wider. Different filtering precisions can be selected according to different environments, and the glass fiber is cheaper than other metal materials, so the stainless steel oil filter core uses glass fiber as the filter material.
Therefore, the selection of the filter material of the Hedeck filter is to use different filter materials according to the different working environment and cost performance of the customer. Some of the skeletons need special treatment and use. The specially treated oil filter core material can achieve the following functions: finishing high Accuracy size, uniform appearance, high pressure resistance, corrosion resistance to low carbon steel. The surface of stainless steel is coated with wear-resistant coating such as titanium nitride to make the surface of the skeleton beautiful and durable. The metal surface is degreased, sandblasted, stainless steel pickling and passivation, and stainless steel electrochemical polishing to achieve durability and beautify appearance; stainless steel The surface is plastic coated, durable and resistant to acid and alkali corrosion.
Hedeck filter in the manufacturing process should pay attention to the following matters: in the process of skeleton spheronization, it should be noted that the distribution characteristics of the hole should meet the requirements of the mechanics, so that the punched hole is evenly stressed in the spheronization and joint, so in the process of use The medium skeleton is durable, generally it has to be rounded according to the characteristics of the hole type, so that the holes are staggered, so that according to the mechanical point of view, the force of the skeleton is uniform, the life will be greatly improved, the skeleton should be removed from the flash, the burr, the welded joint, and the weld should be Finishing is smooth. The skeleton punched surface should be away from the filter layer to avoid damage to the filter layer.
