Description
Technical field
Technical field of sewage treatment equipment is the utility model is related to, hangs and loads in particular to a kind of reflux pump pump housing
Put.
Background technology
Existing sewage disposal hangs drawing fixedly connected part with external reflux pump, is in no any protection device with stainless steel bolt
In the case of hanging frame is directly connected with the pump housing, the vibrations of the pump housing operationally make stainless steel bolt and fixedly connected part it
Between lasting abrasion, therefore, external reflux pump hang draw fixedly connected part and bolt easily in a short time because serious wear and caused by
Fracture, so when lift overhaul of the equipments so that external reflux pump can not be checked by normal lifting, it is necessary to expend substantial amounts of manpower with
Material resources, and the external reflux pump of damage could be lifted after cutting off the water, waste time and energy, considerably increase the cost of overhaul,
The efficiency of sewage disposal is dragged down.
Utility model content
For above-mentioned problems of the prior art, the utility model provides a kind of reflux pump pump housing and hangs drawing device, this
Device sets nylon jacket between bolt and adapter sleeve, avoids the hard contact between bolt and adapter sleeve, significantly reduces spiral shell
Abrasion between bolt and adapter sleeve.
To achieve the above object, the utility model provides following technical scheme：
A kind of external reflux pump pump housing hangs drawing device, and the pump housing is provided with lug with threaded hole, and the drawing device that hangs includes connecting
Female connector and suspending bars, the adapter sleeve are U-shaped, and the adapter sleeve is 2, is fixedly connected respectively with the both ends of suspending bars, described
Adapter sleeve is enclosed on the lug, and the both sides of the adapter sleeve are respectively equipped with connecting hole, connecting hole, spiral shell described in screw bolt passes
Pit and connecting hole, the adapter sleeve is fixedly connected with lug, nylon jacket, the spiral shell are provided between the adapter sleeve and bolt
The both ends of bolt are screwed with nut.
Further, the suspending bars are U-shaped.
Further, the suspending bars are provided with a crossbeam, and the lower surface of crossbeam is plane.
Further, the nylon jacket side is provided with flange, and the flange is between nut and adapter sleeve.
Further, it is additionally provided with rubber ring between the adapter sleeve and the lug.
The beneficial effects of the utility model are as follows:
1st, the utility model uses U-shaped adapter sleeve, and is symmetricly set on the both ends of suspending bars, when lifting the pump housing, two
Individual lug uniform force, avoids stress concentration, extends the service life for hanging drawing device and pump housing lug；
2nd, the utility model sets nylon jacket between adapter sleeve and bolt, avoids directly connecing between adapter sleeve and bolt
Touch, hence it is evident that reduce the abrasion condition of bolt and adapter sleeve.

Embodiment
In order that those skilled in the art more fully understand the technical solution of the utility model, with reference to of the present utility model
Accompanying drawing, clear, complete description is carried out to the technical solution of the utility model, it is general based on the embodiment in the application, this area
Other similar embodiments that logical technical staff is obtained on the premise of creative work is not made, should all belong to the application
The scope of protection.
Embodiment one：
As depicted in figs. 1 and 2, a kind of external reflux pump pump housing hangs drawing device, and the pump housing is provided with 2 lugs 4 with threaded hole,
Hanging drawing device includes suspending bars 1 and adapter sleeve 2, and adapter sleeve 2 is U-shaped, and adapter sleeve 2 is 2, and the both ends with suspending bars 1 are consolidated respectively
Fixed connection, adapter sleeve 2 are enclosed on the lug 4, and the both sides of adapter sleeve 2 are respectively equipped with connecting hole 21, and bolt 5 sequentially passes through connection
Hole 21, screwed hole and connecting hole 22, adapter sleeve 2 is fixedly connected with lug 4, connecting hole 21, the aperture of connecting hole 22 are more than spiral shell
The diameter of bolt 5, is provided with nylon jacket 3 between adapter sleeve 2 and bolt 5, the both ends of bolt 5 are screwed with nut 6.The side of nylon jacket 3 is provided with
Flange 31, for flange 31 between nut 6 and adapter sleeve 2, nut 6 is stop nut, is so limited nylon jacket 3 by nut 6
It is scheduled between adapter sleeve 2 and bolt 5.Rubber ring 7 is provided between adapter sleeve 2 and lug 4, rubber ring 7 is enclosed on bolt 5.Hang drawing
The generally U-shaped of bar 1, the top of suspending bars 1 is V-arrangement, and suspending bars are bilateral symmetry, and suspending bars 1 are provided with one close to top end
Crossbeam 11, the lower surface of crossbeam 11 is plane, when hanging the drawing pump housing, first prejudges to hanging drawing scene, is hung if being judged to the pump housing in advance
It will not be shaken during drawing, then the V-arrangement top of suspending bars is only passed through with a chain；If it is judged to send out when the pump housing hangs drawing in advance
Life is rocked, then needs to pass through the crossbeam of suspending bars with two chains, and two chains separate, and reaching prevents the pump housing from being shaken when hanging drawing
Dynamic effect.
In pump housing normal work, hanging drawing device can be fixed together with the lug 4 of state shown in Fig. 2 and the pump housing all the time,
Time between overhauls(TBO) to the pump housing is usually half a year or 1 year, if without the protection of nylon jacket 3 and rubber ring 7, the lasting vibrations of the pump housing
Two side walls and bolt 5,4 continuous collision friction of lug of adapter sleeve 2 can be caused, when hanging the drawing pump housing, bolt 5 and adapter sleeve 2
Easily it is broken, causes the pump housing not sling.And by setting nylon jacket 3 and rubber ring 7 in the utility model, can effectively it avoid
The contact very stiff and demanding with bolt 5, lug 4 of two side walls of adapter sleeve 2, substantially increase the efficiency of pump housing maintenance.In addition, this practicality
It is new to use U-shaped adapter sleeve, and the both ends of suspending bars are symmetricly set on, when lifting the pump housing, two uniform forces of lug 4,
Stress concentration is avoided, extends the service life for hanging drawing device and pump housing lug.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It is appreciated that other embodiment.
