Description
[technical field]
Blower technology field is the utility model is related to, specifically a kind of CVT speed changes Roots blower.
[background technology]
Roots blower category positive displacement blower fan, its principle are to be performed relative motion using two lobed rotors in cylinder to compress
With the rotary compressor of conveying gas.This blower fan structure is simple, easily manufactured, is widely used in aquaculture oxygenation, dirt
Water treatment aeration, cement transportation, it is more suitable for the gas conveying and pressurization of low-pressure occasion, it is also possible to make vavuum pump.
Generally, when motor is power frequency, the air quantity of Roots's machine is fixed, can not be adjusted according to actual required airflow,
Rotation speed of fan can only be adjusted by changing belt pulley, and the rotating speed of belt pulley can only be fixed, can not meet more
High demand.Determine rotating speed and that service efficiency is low also be present.
, it is necessary to increase frequency converter, as China patent CN201521039009.X discloses one kind when from variable-frequency motor
Roots blower with frequency converter, by the combination of roots blower and frequency converter, improve production efficiency and industrial automation is horizontal.
But cost needed for this device being adjusted using frequency converter and mode is higher, and variable frequency adjustment scope be generally 30~
50HZ, can only reduction of speed, can not raise speed, limit the adjustable range of air quantity.
[utility model content]
The purpose of this utility model is solve the deficiencies in the prior art, there is provided a kind of CVT speed changes Roots blower, not
Under conditions of needing variable-frequency motor, change the rotating speed of Roots blower by adjusting CVT speed changers, adjust compressor flow, it is full
Needs under the different operating modes of foot.
To achieve these goals, a kind of CVT speed changes Roots blower is designed, including it is power frequency motor, active wheels, driven
Wheel group, transmission belt and hydraulic pump, active wheels and driven wheels are all made up of movable plate and fixed disk, and side belt wheel can be in axle
Upper slip, opposite side are then fixed, and movable plate and fixed disk are all cone structures, and their conical surface forms V-groove and is driven with V-type
Band engagement, it is characterised in that driving wheel is fixed with motor shaft, and driven pulley is fixed with Roots blower arbor, transmission belt by driving wheel with
Driven pulley connects, and by the pressure change of hydraulic pump, the movable plate of driving wheel and driven pulley moves to different directions respectively, changes
Wheel footpath size ratio, output rotating speed regulation, so as to realize the gearshift adjustment of Roots blower.
Described CVT speed change Roots blower concrete structures are as follows：Roots blower (1) and motor (2) are fixedly mounted on
On base (3), driving wheel (4) is fixedly connected with motor (2), and driven pulley (5) is fixedly connected with Roots blower (1), transmission belt
(6) it is connected respectively with driving wheel (4) and driven pulley (5), motor (2) drives driving wheel (4) rotation, is driven by transmission belt (6)
Driven pulley (5) rotates, and driven pulley (5) drives Roots blower (1) work, is adjusted by the pressure of hydraulic pump, driving wheel (4),
The wheel footpath size of driven pulley (5) can change, and adjust the rotating speed of Roots blower.
The utility model compared with the existing technology, combining structure simple possible, the advantage is that：
1st, the rotating speed of roots blower can carry out electrodeless variable-speed, and air quantity can be adjusted as needed, can be with automatic control system
System is associated；
2nd, without variable-frequency motor and frequency converter, cost is reduced；
3rd, fan efficiency is improved, reduces energy consumption.
