China Manufacturer for Element Air Filter - Rfa Tank Mounted Mini-Type Return Filter Series – Xinyuan Detail:

The filter is installed on the top of the oil tank to keep the oil flowing back to the oil tank clean. The filter is used to remove the contaminants such as metal particles and rubber impurities of the sealing parts in the hydraulic system, the tube body part is immersed into the oil tank and is provided with devices such as by-pass Valve, diffuser, temperature core pollution clogging transmitter, etc. . The utility model has the advantages of compact structure, convenient installation, large oil-passing capacity, small pressure loss, easy core replacement, etc. .

This kind offiltercan be used in hydraulic system forfinefiltration. It can be installed on the cover of the tank. The filter head should be out of the tank and the filter bowl should immerse in the oil. The inlet port has threaded and flanged connections. The filter has indicator and by pass valve. Whenthe dirt accumulates in the filter element or the temperature of the system is too low, and the oil inlet pressure reaches 0.35MPa, the indicatorwill give signals showing that the filter element should be cleaned, changedorraise the temper ature. If no service is doneand asthe pressure reaches to 0.4 MPa, the by pass valve will open automatically to keep the hydraulic system safe. It is easy to change filter element and to inject the oil to the tank: open thefiltercover, the filterelement could be changed orthe oilcanbe injected into tank. Two oil ports atfilter head which are M18X1.5, the indicatorcan be installed ata- ny part and they can filter some oil which may return to the tank. The filter has fluid diffuse. The fluid diffuser is at bottom of the filter and can help the medium flow stably to the tank and avoid the air reentering. The filter element is made of glass fiber, so it has high filtration accuracy, low initial pressure loss, high dirt-holding capacity and so on. Filter radio B 3, 5,10,20^200,filteref- ficiency nN99.5%, and fit the ISO standard.

1. It is easy to install and connect, and simplify the system pipeline. The filter Shudan is connected to the cover plate of the oil tank, the temperature head of the superheater is exposed outside the oil tank, the oil return cylinder and body are immersed in the oil tank, and the oil inlet is connected with pipe and Flange, thus simplifying the system pipeline, make the system layout more compact, installation and connection more convenient.

2. To improve the reliability of the hydraulic system, a leakage core pollution transmitter and an oil bypass valve are installed. When the temperature core is blocked by contaminants or the temperature of the system is over 4 °C, the flow rate fluctuates and other factors cause the oil pressure to be fed, and the pressure is 0.35 MPA, the transmitter will send out a signal indicating. Should replace the temperature core or increase the oil, liquid temperature. At this time can not immediately stop to deal with these failures, set in the leakage core under the bypass valve, automatic open work (bypass valve open pressure of 0.4 MPA) , to protect the leakage over and hydraulic system, Normal Work.

3.It is very convenient to replace the leaking core or fill the oil tank by unscrewing the temperature cap of the leaking device (the cleaning cap) . There are two M18 x 1.5 oil ports in the temperature head, can Be installed in either side of the transmitter or system a small amount of oil back, the flow of fuel tank overheating.

4.The diffuser with a liquid flow diffuser is arranged at the bottom of the return oil cylinder body, which can make the returning oil medium flow smoothly into the oil tank and avoid the formation of air bubbles, thereby reducing the re-entry of air and the disturbance of the deposited pollutants.

5.Glass fiber core has the advantages of high over-temperature precision, high oil-passing ability, small original pressure loss and large pollution capacity. Its filtering precision is calibrated with absolute over-source Chroma, over-drop ratio 03,5,10,20N200, over-temperature, NN99.5% efficiency, in line with ISO standard.
