Detailed description

5:  6 gear ratio of screw rotor is employed for all RCB series,with the oversize diameter rotor,ultra low rotate speecand low energy consumptionithe high effciency mechanical characteristic of big air displacement can beachieved,the efficiency is 5% ~ 15% higher than the counterpart product of other brands and the rotate speed ofscrew is 35% lower than the counterpart product of other brands.lt features durability,low-noise and other
advantages.
Intelligent display controI:More convenient in supervision by working with air compressors.Overall management

can be done from office computers.

一 High efficiency output

Big rotor low speed so that each unit brake horsepower relative can produce more gas. We make the space between the rotors called " leakage path ", " small rotor leakage path " than the greater trochanter of the much larger, faster and the rotation of the rotor bearing wear more big, drag coefficient is bigger, coupled with the gear or belt friction. Small rotor efficiency loss greatly increased energy consumption. 

The service life of the compressor depending on:

* the screw host -- > speed -- > bearing -- > screw rotor diameter and speed determines the exhaust volume. In theory, this means to produce the same amount of air compression chamber, the smaller the small rotor must be relatively large compression cavity of the greater trochanter to turn faster. Fast speed, oil cycle increased, speed up the oil deterioration time, causing the machine oil high temperature, long time under high temperature, circulation, more effect on oil and gas oil separator into life. The rotor is your compressor to replace parts of the most expensive, and it also determines the most running costs.

Rotor tooth profile is --5~6 vs. 4~6 tooth profile

Project

4 to 6, toothed

5 to 6 toothed

Number of teeth

Shaped teeth less pressure large rotor gap

Rotor gap to reduce the pressure drop, reducing the amount of the high pressure gas leak back to increase the volumetric efficiency.

Bearing spacing

Pitch longer, running, gear and rotor short-lived flexing

Spacing shortest, flexing minimum, the diameter of the rotor design

Air sealing line

Rotor reduce the flow of compressed gas back to the gas seal line, but the bearing is approaching the end of its useful life, the bearing clearance to expand gas seal line produces severe wear, reduce efficiency, and even burned body

Unused gas seal line, the number of teeth to maintain the efficiency of the design of the rotor

 

5 to 6 the advantages of the toothed

(1)Back to the blow hole small

(2)Yin and yang rotor airtight better

(3)The same outer diameter of the rotor, its displacement to a large

(4)The rotor high precision by experiment that when the gap will be reduced to 1% of the volumetric efficiency increase 0.01mm.
