Abstract
A waterproof maze structure on a permanent magnet speed regulator comprises a rotating shaft and a waterproof outer sleeve. The rotating shaft is provided with waterproof grooves. The waterproof outer sleeve is composed of an edge cylinder and an annular disc. The edge cylinder is vertically fixed on the annular disc. The rotating shaft penetrates through the edge cylinder, and a gap is reserved between the edge cylinder and the rotating shaft. The inner wall of the edge cylinder is arranged into an acute angle structure which is beneficial for water in the waterproof grooves to flow out and has a gradually-increased radius. The waterproof outer sleeve is sleeved on the rotating shaft and connected with the rotating shaft through a bearing. The waterproof outer sleeve is fixed on an equipment end through the annular disc. According to the waterproof maze structure of the utility model, the structure is simple and the process and manufacture is easy; and by virtue of simple reconstruction of the structure, the effect of centrifugal force is fully utilized to discharge internally accumulated water out of equipment, thereby achieving the objective of protecting the equipment.
Description
Technical field
The utility model relates to a kind of cooling device, relates in particular to the anti-water maze on permanent-magnet speed governor.
Background technology
Along with the development of permanent-magnet speed governor industry, permanent magnetic speed-adjusting equipment becomes replacing fluid coupling, frequency conversion equipment in the main speed regulator of industrial circle energy-saving and emission-reduction.From permanent-magnet speed governor develops at home, permanent magnetic speed-adjusting equipment ubiquity heat dissipation problem, thereby copper conductor rotor can produce the magnetic induction effect that a large amount of heats affects p-m rotor in equipment running process, in order to address this problem, current domestic implementation two schemes: a kind of is water-cooled cooling; A kind of is wind cooling temperature lowering.But air-cooledly can only solve small-power permanent-magnet speed governor heating problem, water-cooled generally is used on powerful permanent magnetic speed-adjusting equipment.Also having introduced new problem on the basis solved at heat dissipation problem, is exactly the water proofing property problem.Traditional permanent-magnet speed governor reckons without the flow pass behind water access arrangement inside on structure arranges, just externally adopt oil seal technique to carry out the physics waterproof, but due to the equipment long-time running, thereby water can stockpile operating efficiency and the service life that has affected equipment at device interior under the effect of centrifugal force.
Summary of the invention
The technical problem that the utility model solves is in equipment running process, splash the effect due to centrifugal force after device interior for the water of cooling and can accumulate in equipment oil sealing place, the utility model makes by the transformation of equipment inner structure the water outflow equipment under the effect of centrifugal force stockpiled, thereby reach the effect of real sealing, for society provides a kind of simple in structure, good water-proof effect, is easy to the anti-water maze of permanent-magnet speed governor of processing and manufacturing.
For the purpose the technical solution adopted in the utility model that reaches utility model is:
Waterproof labyrinth structure on a kind of permanent-magnet speed governor, comprise rotating shaft, waterproof casings cylinder, and described rotating shaft is provided with the waterproof groove; Described waterproof casings cylinder is comprised of limit cylinder and circular disk, and described limit cylinder is vertically fixed on circular disk; Described rotating shaft is through the limit cylinder, and leave gap between limit cylinder and rotating shaft, the inwall of described limit cylinder is arranged to be beneficial to the acuter angles that radius that water in the waterproof groove flows out increases gradually, described waterproof casings jacket casing is contained on rotating shaft, by bearing, with rotating shaft, be connected, the waterproof casings cylinder is fixed by circular disk and equipment end.
At least be provided with two above waterproof grooves on rotating shaft described in the utility model.
Be provided with special double oil seal between bearing described in the utility model and waterproof casings cylinder.
Beneficial effect:
Anti-water maze on a kind of permanent-magnet speed governor of the utility model, simple in structure, be easy to processing and manufacturing, the simple transformation by mechanism, take full advantage of centrifugal action, and inside is stockpiled to the water device for transferring, reaches the purpose of protection equipment.
The accompanying drawing explanation
Fig. 1 is the waterproof labyrinth structure figure on a kind of permanent-magnet speed governor of the utility model.
Fig. 2 is the waterproof labyrinth structure figure of the utility model embodiment 2.
Embodiment
Below in conjunction with embodiment, the enforcement of the utility model scheme is described in more details:
Embodiment 1: the waterproof labyrinth structure figure of equipment rotating part
Fig. 1 is the described optimum structure schematic diagram of the utility model; The described waterproof labyrinth structure of the utility model comprises a rotating shaft 2 and a waterproof casings cylinder 7, be provided with a plurality of annular grooves on rotating shaft 2 as waterproof groove 3, waterproof casings cylinder 7 is comprised of limit cylinder 1 and circular disk 4, rotating shaft 2 is through waterproof casings cylinder 7 and leave minim gap between the two, on the circular disk 4 of waterproof casings cylinder 7, a plurality of bolts hole are set, circular disk 4 is connected with equipment end by bolt; The inwall of limit cylinder 1 is arranged to be beneficial to the acuter angles 6 that radius that water in the waterproof groove flows out increases gradually, the i.e. 2 one-tenth acuter angles 6 as shown in Figure 1 in limit cylinder 1 cross section and rotating shaft.
When equipment normally moves, current meeting access arrangement inside for cooling, a part is directly got on waterproof casings cylinder 7, a part splashes 3 li of grooves, rotating shaft 2 drives waterproof casings cylinder 7 and runs up, current can splash in waterproof groove 3, current are thrown to limit cylinder 1 inwall under the effect of centrifugal force, and along the gradient separation instrumentation of limit cylinder 1 inwall, simultaneously for to prevent that trickle steam from entering bearing 8, be provided with special double oil seal 5 between bearing 8 and waterproof casings cylinder 7, thereby reached the purpose of double-deck waterproof.
Embodiment 2: the waterproof labyrinth structure of equipment non-rotating part
The anti-water maze of equipment non-rotating part, be comprised of waterproof casings cylinder 7, rotating shaft 2, waterproof groove 3 as shown in Figure 2.Waterproof casings cylinder 7 comprises circular disk 4 and limit cylinder 10 two parts, and waterproof casings cylinder 7 is bolted with load end, and rotating shaft 2 passes waterproof casings cylinder 7 and do not contact, and both connect by bearing 11.
When equipment normally moves, cooling water flows into device interior, rotating shaft 2 is in the High Rotation Speed state, and waterproof casings cylinder 7 now remains static, enter bearing 11 for preventing water smoke, bearing 11 is damaged, one oil sealing 9 is installed between bearing 11 and waterproof sleeve 7 and for the water droplet that prevents from splashing, is infiltrated bearing 7, a plurality of annular grooves are set as waterproof groove 3 on rotating shaft 2, understand under the effect at gravity device for transferring slowly when water droplet enters in waterproof groove 7.
The technical solution of the utility model also not only is confined to the above embodiment; but they can play the effect of drawing inferences about other cases from one instance, casting a brick to attract jade; can be more Designing Product in Series technical scheme is provided; as long as change, modification, replacement, combination and simplification that other the essence that does not deviate from technical solutions of the utility model is made, all should be within protection range of the present utility model.
