Best Quality China Manufacturer High Efficient Quality Sllf Duplex Oil Purifier Filter

A. Pressure line filter:

Pressure pipeline filters can be installed on pressure pipelines of different pressure levels to further remove or block impurities caused by wear and tear caused by externally introduced components and the chemical action of the medium itself. Particularly suitable for automatic control systems and servo systems. It can prevent high-precision control elements and actuators from being worn out or stuck prematurely due to contamination, thereby reducing failures and extending component life. The filter uses imported glass fiber filter material, which has the advantages of high filtration accuracy, strong oil permeability, small original pressure loss, and large dirt holding capacity. Evaluation method is ISO16889-99 and GB / T18853-2002

Features:
1.Compared with the same flow filter, the structure is compact and small.

2. Wide pressure range.

3. It is convenient to change the filter element. The user can open the upper cover and replace the filter element according to the installation space, and can also unscrew the casing (put the oil first) and remove the filter element from below.

4. Convenient installation and fixation: If the user has difficulty in installing according to the standard flow direction, he can remove the 4 screws on the cover and turn the cover 180 degrees, which changes the direction of the medium flow.

5. The filter is equipped with a bypass valve and a pressure difference signalling device, with dual protection functions. When the filter element is contaminated and the pressure difference between the inlet and outlet is at the value set by the signalizer, the signaler will send a signal and the filter element must be replaced at this time. 

B. Oil return filter

It is installed on the oil return line at the end of the system, and its role is to filter out the pollutants generated or intruded in the system before returning to the fuel tank. Therefore it is one of the most important filters to control the cleanliness of the system pollution. Although it is a low-pressure pipeline, depending on the operating conditions of the transmission, pulsations or pressure shocks may also occur. Therefore, the material and strength of the components must be fully considered. 

Features:

The material of the oil return filter element is mainly divided into glass fiber type, paper type, mesh type and line gap type.
Glass fiber filter element has the advantages of high filtration accuracy, large oil permeability, less original pressure loss, and large dirt holding capacity. The filtration accuracy is defined according to the filtration ratio β3, 5, 10, 20> 100. Can not be cleaned and used repeatedly, and must be replaced when the filter element is blocked.
Paper filter element, compared with glass fiber, the overall performance is weak, the filtration accuracy is defined by the manufacturer according to the nominal accuracy. Can not be cleaned and used repeatedly, and must be replaced when the filter element is blocked. The price of paper filter element is slightly lower, and it is more widely used.
Mesh type and line gap type generally use metal wire mesh as the filtering material. The advantage is that it can be cleaned repeatedly and used many times. The disadvantage is that the filtering effect is poor, and it is now rarely used in hydraulic oil return pipelines.

C. Suction filter

This filter is a coarse filter and is generally installed at the oil suction port of the oil pump to protect the oil pump from inhaling large mechanical impurities. The filter has a simple structure, a large oil passing capacity, and a small resistance. And there are two types of pipe, flange connection, sub-network type, line gap type. The oil suction filter can be installed directly on the side, upper or bottom of the fuel tank. The oil suction cylinder penetrates below the liquid level in the fuel tank. The oil suction filter head is exposed outside the fuel tank. And other devices so that the oil in the tank will not flow out when replacing the filter element and cleaning the filter element.

Features:

1. The oil suction filter is provided with a machine pollution baffle to ensure that the pollutants deposited in the filter element can be removed together with the filter element when the filter element is replaced without contaminating the fuel tank.
2. This series has self-sealing valve which can be directly installed on the top, side or bottom of the fuel tank. When maintenance is needed to open the filter cover, the self-sealing valve will automatically close, so that it can be guaranteed even if it is submerged below the liquid level in the oil-filled tank. Filter maintenance work.
