The utility model discloses an advantage with positive effect is: the utility model discloses cool off the air -blower and adopt the air -cooled structure of integration, simple structure in installation, dismantlement, change and maintenance, the device and fan power supply separation, the control of being convenient for, need not water and cooling tower, the cost saving, require lowly to service environment, the centering cooling, the bearing cooling effect is better, to the product that uses the sound insulation cover, make the air current more unobstructed, service condition improves.
Description
Technical field
The utility model belongs to Roots blower cooling technology field, particularly relates to a kind of forced air cooling Roots blower.
Background technique
Roots blower is a kind of displacement blower with the conveying gas features such as oil-containing, stability of flow, structure be not simple, has extensive use in gas conveying and strength transportation art.Because Roots blower does not have interior compression, so temperature rise phenomenon is obvious, especially the temperature rise of bearing and lubricant oil is higher, limits the high-pressure trend of Roots blower.In order to solve Roots blower problem of temperature rise, mainly contain four kinds of implementations at present:
The first scheme: allow Roots blower use under low pressure operating mode, but its application area is limited by very large;
First scheme: in order to realize high-pressure trend, adopts water-cooling pattern, namely to blower and wallboard, fuel tank increase cooling jacket, and access circulating water cooling;
The third scheme: by extending impeller shaft to outside fuel tank, increasing centrifugal blower at axle head and carrying out air-cooled;
4th kind of scheme: realize high-pressure trend by the two-stage series connection of blower, the cooling of middle increase condenser.
The shortcoming that above four kinds of schemes exist is: one, and roots blower cannot realize high pressure; Its two, water-cooling structure is complicated, and installation and maintenance are inconvenient, and there is potential safety hazard, and application area is restricted, and has requirement, if use circulating water, causes the waste of water resources, if do not have circulating water, then need to set up cooling tower, increase cost to use facility; Its three, product structure is complicated, increases manufacture cost, and fan is eccentric, cooling misaligns fuel tank, and cooling effect is restricted, and the impeller shaft of lengthening reduces the intensity of axle, and add the risk of damage and reprocess difficulty, cost is high, complex structure; Its four, two-shipper is connected, and cost increases, and floor space is large, maintenance difficult, and failure risk strengthens, and needs equally to configure cooling circulating water.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of pressure and cools Roots blower, adopts independently axial fan module, reaches the object of forcing cooling Roots blower.
The utility model adopts following technological scheme to realize goal of the invention: a kind of forced air cooling Roots blower, comprise Roots blower main body and and increment fuel tank between wallboard, it is characterized in that: on described wallboard, air cooling mechanism is set, described air cooling mechanism comprises axial fan motor and axial fan, described axial fan and axial fan motor are arranged on axial fan motor retainer, described axial fan motor retainer is fixed in protection air guide sleeve, described protection air guide sleeve is connected with described wallboard, between described protection air guide sleeve and described wallboard, gap is set.Realize Roots blower and bearing and lubricant oil and force cooling, extend operating life.
Improvement of the present utility model has, and described protection air guide sleeve arranges air vent, and described protection air guide sleeve arranges one group of inlet hole hole, and described one group of inlet hole orifice ring shape is uniform.
Improvement of the present utility model also has, and between described protection air guide sleeve and described wallboard, arrange shock strut, described shock strut is set to hollow cylindrical, and bolt is placed in one, and described protection air guide sleeve is fixedly connected with by described bolt with described wallboard.Shock strut can be any vibration-absorptive material.
Improvement of the present utility model also has, and described axial fan motor is arranged between described axial fan and fuel tank, and the wind direction of described axial fan is towards described axial fan motor.
Compared with prior art, advantage of the present utility model and good effect are: the utility model carries out cooling to blower and adopts integrated air-cooled module, and structure is simple, are convenient to installation, dismounting, change and maintenance; This device is separated with fan power, is convenient to control; Without the need to water and cooling tower, cost savings; Require low to Environmental Conditions; Centering cools, and bearing cooling effect is better; For the product using acoustic hood, make air-flow more unobstructed, operating conditions improves.
