Material

stainless steel, carbon filter

scope

This filter is widely used in metallurgical machinery, mining machinery , heavy-duty machinery etc hydraulic system.

Working principle

There is only one filter to operation in normally work . You can not stop the system then open the pressure balance valve and roll reversing vales .switch to another filter to work , when the filter pressure loss exceed(more than 0.35 MPa ) and then clean or replace the filter element .

Introduction

Duplex oil return filter SYLQ-BL series is made of two monocular and a change valve . mating BLLX series unite type filter element . The structure of filter simpleness , convenient to use , and with balanced valve and differential pressure send message receptor , in order to reach ensure system security .

operational process:

1. Filter installation is completed , open the inlet and outlet valve of the filter , the system start to working .

2. When the differential pressure transducer is alarm (differential pressure is achieved 0.35MPa), pls change the conversion valve and let another filter to work.

3. Open the vent valve(on the upper cap) and blowdown valve (on the bottom cap), let the dust fluid drain off the filter completely.

4. Open the upper cap of filter , take our the filter element .

5. Clean or change the filter element , then install the filter element and upper cap .

6. Closed the vent valve and blowdown valve and open the inlet and outlet valve of the filter .

7. The best advantage of the duplex filter is when the element need to change or clean , don’t need stop system working .
