(1) Introduction

The filter used in hydraulic systems Oil return filter, filter element metal particles produced by wear in the hydraulic system and the seals rubber impurities and other pollutants that flow back into the oil tank clean.

The filter is installed in the top of the tank, cylinder partially immersed in the fuel tank, and the bypass valve, diffusers, filter pollution clogging the sender and other devices. With a compact, easy to install, through the oil capacity, small pressure loss, easy to replace the filter characteristics.

(2) Performance and Features

1. Install easy connection, simplifying the system piping of the filter is mounted directly on the tank cover, filter filter head exposed outside the tank, immersed in the fuel tank back to the oil barrel, oil inlet tube is provided with a flange connection , thereby simplifying the system piping, the system is more compact layout, installation and connection easier.

2. Set the sender filter pollution, oil bypass valve to improve the reliability of the hydraulic system: When the filter is clogged contaminants or other systems liquid temperature is too low, the flow pulsation factors into the oil pressure is 0.35MPa, the sender device will send a signal indication. Filter should be replaced or increase fluid temperature. When this can not be shut down immediately to deal with these failures, located in the lower part of the filter bypass valve automatically open work (bypass valve opening pressure of 0.4MPa), in order to protect the filter and hydraulic system work properly.

3. Design straight back to the oil filter, replace the filter or to make the fuel tank is very convenient: simply unscrew the filter filter cover (cleaning cover) can replace the filter or the fuel tank and has two M18 × in the filter head 1.5 port, install the sender or the system a small amount of oil reflux tank filtration purposes in any party.

4. The flow diffuser having a diffuser provided at the bottom back to the oil barrel, enabling a smooth flow into the tank, easy to produce bubbles, thereby reducing the air to re-enter, and unrest has weakened pollutants deposited back to the oil medium.

5. The filter is made of glass fiber filter material having a high filtration precision, through the oil capacity, the original pressure loss, pollutant carrying capacity and so on. Its filtration precision absolute filtration precision calibration, filtering than β3,5,10,20≥200, filtration efficiency n≥99.5%, in line with ISO standards.
