High temperature radiating machine seal device, including mechanical seal, the mechanical seal include moving ring assembly and static components,
The mechanical sealing linkage ring component is set on sleeve outer circle, and axis is set on pump shaft, the mechanical sealing static ring component peace
Loaded on gland inner hole, the gland is fixedly mounted by screw and pump cover, and pump cover and gland form seal chamber, and the machinery is close
Envelope is located in seal chamber, and the sleeve outer circle is provided with transmission ring, and transmission ring is located at outside the seal chamber of gland and pump cover composition
The outer circle of portion, the gland and transmission ring is provided with cooling fin, and the transmission ring is fixedly mounted on axle sleeve by being driven screw
In pump shaft outer circle.
Pump shaft outer circle between the transmission ring and bearing housing is provided with heat emission fan, and heat emission fan both ends are evenly equipped with flabellum.
The transmission ring is set as straight grooves transmission ring or oblique groove transmission ring.
The recess sidewall of the oblique groove transmission ring and the angle of oblique groove transmission ring end face are α, and α is 4 °~30 °.
The beneficial effects of the utility model,
1, the method in the groove at original one group of certain distance interval of component Excircle machining to form cooling fin is taken, is increased
Heat dissipation area does not increase cost to original structure substantially without change, and simple good processing is not necessarily to cooling water temperature, anhydrous at the scene
Source still is able to guarantee the normal operation of mechanical seal in the case where being cooled down；
3, straight grooves transmission ring groove is parallel with sealing gland, only increases heat dissipation area, will not generate power consumption, is suitble to small
Power pump-type uses；
4, oblique groove transmission ring groove and sealing gland can also be rotated at angle while increasing heat dissipation area in pump shaft
When drive air flowing, heat dissipation effect is more preferable；
5, heat emission fan two sides are evenly distributed with flabellum, at the same while cool down to mechanical seal and bearing housing can also balancing axial thrust,
Bearing premature breakdown caused by will not being increased because of axial force.
