Abstract
The utility model discloses a titanium fan which comprises a drive shaft, a shell body and a sealing member which is disposed on the drive shaft and fixedly connected with the shell body. Sealing rings are arranged between the sealing member and the drive shaft. The sealing member is composed of a sealing flange and a sealing member body through integrated machining. The sealing member is arranged on the drive shaft in sleeved mode. The sealing flange is fixedly connected with the shell body. The sealing member is in a split-type structure. A rib plate synchronously split is arranged at the split position of the sealing member. Two split half rib plates are separably connected with each other through bolts. The titanium fan comprises the sealing member which is arranged on the drive shaft and fixedly connected with the shell body, and is in the split-type structure. When the damaged sealing rings are replaced, the shell body disposed at the front end of the sealing member, an impeller in the shell body and other parts do not need disassembling. Therefore, replacement is convenient and time is saved.
Description
Technical field
The utility model relates to and belongs to the ventilation equipment field, is specifically related to a kind of titanium blower fan.
Background technique
Blower fan is a kind of common rotating machinery, be divided into according to the purposes difference multiple, such as gas fan, air bells exhauster, centrifugal blower and circulating fan etc.In most cases, the sealing of blower fan does not need very tight.
Development along with the blower fan technology, its Applicable scope is adjusted by original conveying innocuous gas or as indoor and outdoor air, expanded toxic gases such as carrying coal gas, hexane gas, hydrogen chloride gas to, or even the harmful medium such as radioactive air, this just requires the sealability of blower fan very good, otherwise Leakage Gas causes environmental pollution, is detrimental to health.
For solving the problems of the technologies described above, need provide a kind of good seal performance, nothing to leak, can be widely used in the titanium blower fan of the conveying of chemical industry harmful gas.
Summary of the invention
The utility model purpose provides a kind of titanium blower fan, and by the improvement of structure, the conveying of chemical industry harmful gas is leaked, can be widely used in to good seal performance, nothing.
For achieving the above object, the technical solution adopted in the utility model is: a kind of titanium blower fan, comprise blower fan transmission shaft and Blower Housing, also comprise being installed on the blower fan transmission shaft and the seal that is fixedly connected with Blower Housing, be provided with seal ring between described seal and the blower fan transmission shaft;
Described seal is processed by sealing flange and seal body one, described seal is sheathed on the blower fan transmission shaft, sealing flange is fixedly connected with Blower Housing, described seal is split type structure, its subdivision place is provided with by the gusset of synchronous subdivision, is utilized bolt to consist of detachable connection by the two halves gusset of subdivision.
In the technique scheme, offer at least 2 circular grooves on the inner ring surface of described seal, be provided with the described seal ring with blower fan transmission shaft interference fit in the described circular groove.By said structure, do not need the Blower Housing of seal front end and the component such as impeller in the housing are pulled down when the seal that replacing damages or seal ring, it is convenient to change, and saves time.
Preferably, described seal ring is ptfe ring, and is wear-resisting, corrosion-resistant.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1. the utility model comprises and is installed on the blower fan transmission shaft and the seal that is fixedly connected with Blower Housing, the sealing body is split type structure, do not need the Blower Housing of seal front end and the component such as impeller in the housing are pulled down when changing the seal ring that damages, it is convenient to change, and saves time.
2. offer at least 2 circular grooves on the inner ring surface of seal of the present utility model, be provided with the seal ring with blower fan transmission shaft interference fit in it, consist of labyrinth seal structure, performance is good, without leaking Environmental security.
3. seal ring of the present utility model is PTFE, and is wear-resisting, corrosion-resistant.
