1, unique sealing structure
Principle: a liquid inlet pipe through the liquid (gas ) tube flange and cylinder flange connection, the outer end of the packing seal, the leakage possibility minimum.
Advantage.:
To put an end to the inner leakage.
Adopting the outer sealing form, easy to find.
repair convenience : the traditional methods of leakage in cylinder must be found after hanging from the frame, tearing down the barrel shaft, replace the seals, is very difficult, and I plant the use of form, only to press the packing, in a very short period of time to complete, will not affect the normal production.

2, vacuum suction type for improvement
General double cone in the long-term use, suction head is constantly cylinder body turned up material flapping, resulting in vacuum tube bending deformation, deformation after the vacuum tube can not be very good sealing, causing the vacuum drops, even suction head and the vacuum tube welding fracture, in order to reduce the filtration area, reduce the suction head height, I plant will be rounded into a prismatic, to reduce the material and the filter head tapping area can be improved, avoiding the above problems.

3, with quick connectors
Inlet valve and a quick joint, feeding only on the hose, can carry out vacuum pumping material, fast and convenient, can greatly reduce labor intensity.
