I. Xuedian NJXD classifies whether the gas pressure borne by pneumatic lifting rod is unidirectional or bidirectional
(1) single-acting cylinder: the piston of the cylinder can only be pushed by air pressure in one direction, and external force is needed in the reverse direction.
(2) double-acting cylinder: the piston of the cylinder is pushed by air pressure in both positive and negative directions.

 

II. Classification from the installation form of NJXD pneumatic lifting rod
(1) fixed cylinder: the cylinder body of the cylinder cannot be fixed.
(2) axle pin type cylinder: the cylinder body of the cylinder can swing around the fixed axle pin in a certain angle.
(3) rotary cylinder: the cylinder body is usually fixed on the main shaft of the machine tool and can rotate together with the main shaft of the machine tool randomly. This kind of cylinder is often used for pneumatic Chuck on the machine tool.

 

 

III. Classify from the functions and uses of the pneumatic lifting rod of Xuedian NJXD
(1) ordinary cylinder: including single-acting and double-acting cylinders. This type of cylinder is generally used without special requirements.
(2) buffer cylinder: the cylinder is equipped with buffer device, which can avoid strong impact when the piston moves to the end. This kind of cylinder is often used in working occasions with high pressure and high movement speed.
(3) gas-liquid damping cylinder: the cylinder is connected in series with the hydraulic cylinder, which can obtain a relatively accurate movement speed. This kind of cylinder can be used in occasions with high requirements for speed regulation.
(4) swing cylinder: the movement of the cylinder is used as reciprocating rotation around the axis, which can be used for fixture transposition, valve switch, etc.
(5) impact cylinder: it is a kind of high-energy cylinder with high-speed movement of piston rod to form impact force, which can be used for stamping, cutting, etc.

 

 

Xuedian NJXD pneumatic lifting rod special oil for air compressor (mineral oil semi-synthetic oil fully synthetic oil)
Product features:
(1) it has excellent oxidation resistance and thermal stability.
(2) it has excellent high-temperature lubricity and reduces the wear of air compressor.
(3) it has excellent heat dissipation effect and effectively reduces the high temperature generated during the operation of the air compressor.
(4) It has excellent rust resistance and sealing property.
(5) It has excellent emulsifying resistance.
