Abstract
The utility model discloses a pressurizing gas blower, which is mainly used for delivery, pressurization and the like of gas and is also applicable to delivery of gases such as air, sulfur dioxide and the like without severe corrosion. The pressurizing gas blower comprises a base, a compressor body, a motor, a speed changer, a coupler, a spindle, a sealing component, a closed impeller, a case and an air inlet, the compressor body is mounted on the fan base, the motor and the speed changer are further connected onto the base, the motor is connected with the speed changer by the coupler, the sealing component is mounted at the end of the spindle, a pinion is arranged on the spindle, the closed impeller is mounted behind the pinion, and the axial air inlet is disposed outside the case. The pressurizing gas blower is reasonable in structure, high in efficiency, low in energy consumption and excellent in sealing performance, can effectively prevent harmful gas leakage and explosion, and protects the atmospheric environment and personal safety.
Description
Technical field
The utility model belongs to mechanical field, relates to a kind of blower fan, is specifically related to a kind of pressing gas blower.
Background technique
The pressing gas blower is mainly used in conveying, the pressurization of coal gas, and there are shortcomings such as efficient is low, sealing difference in existing gas-blowing engine.Because the medium that blower is carried is a coal gas, has inflammable and explosive property, under the operating mode use condition of high rotating speed, high pressure, cause gas leakage or explosive accident easily, therefore very high to the requirement of blower fan sealing, structural material, should prevent that extraneous air from entering in the machine He behind the coal gas volume mixing certain proportion by shaft end seal blasts, and prevents that again the interior coal gas of machine is to external leakage.
The model utility content
The model utility purpose: for solving the deficiencies in the prior art, the utility model provides a kind of efficient height, pressing gas blower low, good airproof performance consumes energy.
The technical solution adopted in the utility model: a kind of pressing gas blower, comprise base, compressor body, motor, speed changer, coupling, main shaft, sealed member, double shrouded wheel, casing, intake grill, compressor body is installed on the base plate, also be connected with motor, speed changer on the base, motor links to each other by coupling with speed changer, described main-axis end is equipped with sealed member, main shaft is provided with shaftgear, double shrouded wheel is installed behind the shaftgear, and described casing is provided with axial intake grill outward.
As preferably, described coupling is elastic coupling flexible coupling or diaphragm coupling.
As preferably, described sealed member is the triple seal structure, comprises that labyrinth seal, the sealing of floating type carbocyclic ring, nitrogen purge sealing.
As preferably, described double shrouded wheel blade adopts backward bending type list circular arc molded lines or three-dimensional flow vane type line.
As preferably, described shaftgear flute profile is single circular arc monocline tooth, and material is an Alloy Constructional Steel.
As preferably, be provided with a flanged (FLGD) through hole at the axle head position that sealed member is installed, the sealed chamber of this hole UNICOM shaft end seal is inflated inward by this hole, reduces leakage thereby can make labyrinth seal become pneumostop;
As preferably, described double shrouded wheel is welded to one another shaping or blade and wheel disc integral body by wheel cap, blade and wheel disc and mills and make after the shape and the wheel cap welding.
The blower fan that the utility model provides is the blower fan of high rotating speed, high pressure, and rotation speed of fan reaches 9850r/min, and the draught fan impeller linear velocity surpasses 300r/min, and the dust loading of fed sheet of a media is not more than 10mg/Nm
3
Beneficial effect: the utility model compared with prior art; its remarkable advantage is: the utility model has solved shortcomings such as existing pressing gas blower efficiency is low, sealing difference; the material of existing blower fan, impeller, sealing etc. are improved; the pressing gas blower fan structure that provides is reasonable; the efficient height, it is low to consume energy, and sealing is good; can effectively stop the generation of poisonous gas leakage and explosive accident, protection atmosphere environment and life safety.
