120HP tunneling engineering used Screw Air Compressor made in China
Fully seal and double screw,dual shockproof,smooth operation,can be installed anywhere.
With an elegant appearance and compact structure and over a small area.
Low exhaust temperature (only 7°C~10°C higher than the ambient temperature).
The intelligent control system completely satisfy the continuous cooperation without man work.
1.Remarkable Air end:Germany original-building GHH_RAND air end adopts the third-generator dissymmetrical gear shape.The main rotor is five gears and the vice rotor is six gears.
2.As to differences between them is small,the loss of circumfluence is small which increases the cubage efficiency by close to 20% and save the electric currency by about 25% compared to normal screw air compressor.
3.The rotor is dissymmetrical shape,supported by ball bearing and rod bead bearing and operating at a low speed so it can lower the maintenance cost and provide the air end with a longer service life.
4.Gas Intake valve:Controlled by computer,the stable and dependable air displacement air inlet control valve can make the air displacement and power consumption of the motor change along with the air consumption,so as to save energy and electricity,and reduce the operating cost.
5.Oil and gas separator:Screw shaped design of oil and gas separator is easy to uninstall and change.Separator core can separate the left oil in the process of compressing air.After separating,the left oil will be about 1-2ppm.this will increase the cleanness of the compressed air and lower the pollution to the compressed air and lower the pollution to the compressed air and equipment.
6.Oil filters:High-efficient oil separator can remove the impurity from the lubricant and provide clean lubricant for the pump,rotor and bearing.
7.Motor:Famous brand motor with F class isolation and IP54 protecting class.It uses imported SKF durable bearing and can be operated all day long.
