Shield the secret seal system principle of work is what kind of?

When the knife back to rotate, GuiQi shield rubber sealing grease seal inform you through the shield on the pneumatic greasing pump walks to shield main bearing outer seal system for the first row of lip seal before 8 injection point of the circle average spread, to fill the annular space, can effectively avoid impurities into three rows within the soil bin lip seal, and thus avoid into the main bearing, advances the service life of main bearing. Therefore, the working principle of shield and the secret seal system is what kind of? When the shield at the V5 solenoid valve of the secret seal system, the air compressor high pressure gas produced by triplet Z1 of condenser, gas pressure reducing valve, oil mist device, safe check valve V3 into pneumatic greasing pump P2, pneumatic greasing pump work in under the action of gas pressure, down from pneumatic greasing pump suction mouth without pressure of shield machine rubber sealing grease ( Seal) , out of the export pump high pressure sealing grease, high pressure sealing grease the cut-off valve 1 v002 walks to shunt 1 v001, eight gear in a high-pressure sealing grease propulsion shunt motor rotation, and eight equal parts of share out bonus sealing grease injection respectively to the first row of lip seal before eight injection points. After manual regulate z1 gas pressure reducing valve in the gas pressure can control pneumatic greasing pump pumping pressure ( Every increase 1 bar pressure pneumatic grease pump injection can increase 50 bar pumping fat HBW pressure) , to control the gear rotational speed of the shunt, reach the purpose of control HBW grease injection rate. Using three five-way valve 1 p001 can shield barrels of rubber seal fat complete change.
