QU-E LEEMIN pressure line filter

Brief introduction

QU-E LEEMIN pressure pipeline filter also known as oil filter, is a high pressure pipeline oil filter produced by Aite environmental protection, can be installed on the hydraulic system pressure pipe, to filter the hydraulic oil mixed with mechanical impurities and hydraulic oil itself chemical changes produced by gum, leachant, carbon slag, etc. So as to prevent the spool stuck, throttle orifice gap and damping hole plugging and hydraulic components too fast wear and other failures. The filter filter effect is good, high precision, but it is difficult to clean after plugging, and the filter element must be replaced.

The filter is provided with a pressure difference signaling device, when the filter element pollution is blocked to the inlet and outlet pressure difference of 0.35MPa, that is, the switch signal is issued, then replace the filter element, in order to achieve the purpose of protecting the system. The filter element is made of new chemical fiber filter material, which has the advantages of high filtration accuracy, large oil passing capacity, small original pressure loss, large amount of pollution, etc. Its filtration accuracy is calibrated by the filter accuracy, filtration ratio 93, 5, 10, 20>100, filtration efficiency n> 99%, in line with the ISO standard.

Technical parameter

1. Nominal flow L/min: 10-400

2. Filtration accuracy µm:1-30

3. Connection form: tubular plate flange type

4. Nominal pressure: 1.6Mpa

5. With the sending device, the filter element replacement pressure difference is 0.3-0.35Mpa

Product characteristics

1. The filter element adopts glass fiber filter material

It has the advantages of high filtration accuracy, large oil capacity, small original pressure loss, large amount of contamination and so on. Its filtration accuracy is calibrated with the highest filtration accuracy, filtering ratio β3, β5, β10, β20>200, filtration efficiency η "99.5% in line with ISO standards

2. Easy installation and connection, simplifying the system pipeline

Direct return type oil filter can be installed directly on the side of the tank, at the bottom or upper, the filter head is exposed outside the tank, the oil suction body is immersed in the tank below the liquid level, the oil outlet is provided with a tube type, flange type connection, the filter is provided with a self-sealing valve and other devices, so that the pipeline is simplified and easy to install.

3. Set the filter element pollution signal and the oil road valve to improve the reliability of the hydraulic system:

When the filter element is blocked by pollutants or the system liquid temperature is too low, flow pulsation and other factors caused by the oil inlet pressure of 0.35MPa, the transmitter will send a signal indicating that the filter element should be replaced in time or the temperature should be increased, so that it can not immediately shut down to deal with the fault, the bypass valve on the filter element will automatically open (open pressure of 0.4MPa), To protect the filter and hydraulic system working normally.

Application field
