Abstract
The invention belongs to a pneumatic element, and particularly relates to an impeller-typed pneumatic motor of a mine-used lifesaving cabin. An air inlet (5) is formed in a left end circumference of an outer shell body (6) and an air outlet (9) is formed in a right end circumference of the outer shell body (6). The air inlet (5) and the air outlet (9) are communicated with a inner cavity of the outer shell body (6). The inner cavity of the outer shell body (6) is in a cone shape. The air inlet (5) is communicated with a big end and the air outlet (9) is communicated with a small end. An end cover (3) is fixedly connected with the outer shell body (6) through a connecting screw (4) in a threaded mode. A front supporting bearing (2) is installed inside the end cover (3) and a back supporting bearing (11) is installed on the right end surface of the outer shell body (6). A cone-shaped motor impeller is installed in the inner cavity of the outer shell body (6). A front power-output shaft (1) of the motor impeller (7) is installed inside the front supporting bearing (2) and a back power-output shaft (10) of the motor impeller (7) is installed inside the back supporting bearing (11). The motor impeller (7) is provided with a spiral blade (8). The impeller-typed pneumatic motor of the mine-used lifesaving cabin has the advantages of being simple in structure, small in size, light in weight, long in working life, stable in operation, small in vibration and low in noise.
Description
Technical field
The invention belongs to pneumatic element, particularly a kind of mine escape capsule impeller type pneumatic motor.
Background technique
Because pneumatic motor has work safety, burn-proof and explosion prevention, anti-electromagnetic interference, high temperature resistant, stepless time adjustment, starting torque is high, start and stop are rapid, non-environmental-pollution, volume are little, lightweight, rotating speed and the good characteristic such as the power excursion is wide, therefore be used widely in different production fields, and in a lot of industrial fields or high-risk application, pneumatic motor is best or even unique selection.But existing Pneumatic motor structure is complicated, requirement on machining accuracy is high and processing difficulties, assembling and maintenance inconvenience, is difficult to satisfy the user demand of down-hole salvage boat.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of volume little, lightweight, be easy to the mine escape capsule impeller type pneumatic motor dismantling and safeguard.
the technological scheme that technical solution problem of the present invention adopts is: mine escape capsule impeller type pneumatic motor comprises frame, end cap, attachment screw, seal ring, before, the rear support bearing, suction port, relief opening, be characterized in that frame left end circumference is provided with suction port, the right-hand member circumference is provided with relief opening, suction port, relief opening is communicated with the frame inner chamber, the frame inner chamber is taper, suction port is communicated with large end, relief opening is communicated with small end, be threaded with attachment screw between end cap and frame fixing, and seal with seal ring, insert front support bearing in end cap, frame right side insert rear support bearing, the motor impeller of taper is housed in the frame inner chamber, the front pto＝power take-off of motor impeller is installed in the front support bearing, the rear power output shaft of motor impeller is installed in the rear support bearing, the motor impeller is provided with spiral blade.
The invention has the beneficial effects as follows: mine escape capsule impeller type Pneumatic motor structure is simple, and volume is little, lightweight, long working life, be convenient to make and safeguard, operate steadily, vibrate little, noise is low, can satisfy down-hole salvage boat air circulation requirements of one's work fully.
Description of drawings
Illustrate with embodiment below in conjunction with accompanying drawing.
Fig. 1 is that figure cuts open in mine escape capsule impeller type Pneumatic motor structure office.
In figure, pto＝power take-off before 1-; 2-front support bearing; The 3-end cap; The 4-attachment screw; The 5-suction port; The 6-frame; 7-motor impeller; The 8-blade; The 9-relief opening; The 10-rear power output shaft; 11-rear support bearing; The 12-seal ring.
Embodiment
Embodiment, with reference to accompanying drawing 1, the frame 6 left end circumference of mine escape capsule impeller type pneumatic motor are provided with suction port 5, the right-hand member circumference is provided with relief opening 9, and suction port 5, relief opening 9 are communicated with frame 6 inner chambers, and frame 6 inner chambers are taper, suction port 5 is communicated with large end, and relief opening 9 is communicated with small end.Be threaded fixing with attachment screw 4 between end cap 3 and frame 6, and seal with seal ring 12. the interior insert front support of end cap 3 bearing 2, frame 6 right side insert rear support bearings 11, in frame 6 inner chambers, motor impeller 7 is housed, the front pto＝power take-off 1 of motor impeller 7 is installed in front support bearing 2, the rear power output shaft 10 of motor impeller 7 is installed in rear support bearing 11, and motor impeller 7 is provided with spiral vane 8.
The working principle of mine escape capsule impeller type pneumatic motor is: pressurized air enters from suction port 5 the large end that frame 6 inner chambers promote the motor impeller 7 of taper, because blade 8 is that spirality, motor impeller 7 are taper, make the pressurized air that enters in frame 6 be made motor obtain larger kinetic energy by the variation of flow field patterns, realize the rotating mechanical energy of motor impeller 7, air is discharged by relief opening 9, installs impeller on forward and backward pto＝power take-off 1,10 additional and can realize air circulation in salvage boat.
