Pump

Technical field

This utility model is related to a kind of device, particularly to a kind of pump.

Background technology

Pump extensive application in productive life, pump be mainly used to convey water, oil, acid ＆ alkali liquid, emulsion, suspended emulsion and The liquid such as liquid metal, also can convey liquid, gas mixture and the liquid containing suspended solids.Pump generally can be divided into by operation principle Positive displacement pump, dynamical type pump and other types pump three class.In the production of chemical industry and oil sector, raw material, semi-finished product and finished product It is liquid mostly, and raw material is made semi-finished product and finished product, need through complicated technical process, pump plays during these Conveying liquid and provide chemical reaction pressure flow effect, additionally, also adjust temperature with pump in a lot of devices.? In agricultural production, pump is the main mechanical facilities of irrigation and drainage.China rural area is with a vast territory, and annual rural area is required for substantial amounts of pump, typically comes Say agricultural pump account for pump total output more than half.In mining industry and metallurgical industry, pump is also using most equipment.Mine needs to use Pump drainage, in ore dressing, smelting and the operation of rolling, need to be supplied water with pump.Pump is typically made up of multiple parts, when in pump at present After damaging occurs in part, need integrally to break pump, the parts such as internal impeller could be repaired or replaced, so keep in repair Get up to need the long period, be unfavorable for Quick overhaul.

Utility model content

For the defect of prior art, this utility model provides a kind of pump.

A kind of pump, the upper lid 2 including one and the lower bottom base 12 of one, described lower bottom base 12 has two cantilevers stretching out 1, described cantilever 1 is connected with left bearing bearing 11 and right bearing bearing 8 respectively, described left bearing bearing 11 and right bearing bearing 8 Inside be provided with left bearing and right bearing, axle 4 is supported by described left bearing and right bearing, described lower bottom base 12 has with described on Cover 2 corresponding lower covers 13, the chamber accommodating impeller 3 is formed with described upper lid 12 by described lower cover 13, described impeller 3 is fixed on On described axle 4, the arranged on left and right sides of described chamber is sealed by the first sealing ring 5, and the upper and lower opening of chamber forms water inlet Mouth and outlet, the left and right two ends of described upper lid 2 and described lower cover 13 are provided with axle sleeve 6, and described axle 4 is located at described axle sleeve 6 Interior, axle sleeve 6 is sealed by the second sealing ring 10.

The beneficial effects of the utility model are：The replacing of impeller can be conveniently accomplished, greatly reduce maintenance time.

Brief description

Fig. 1 is the schematic diagram of this utility model pump.

Specific embodiment

Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings to this The specific embodiment of utility model is described in detail, and so that above and other purpose of the present utility model, feature and advantage is incited somebody to action Become apparent from.Identical reference instruction identical part in whole accompanying drawings.Not deliberately accompanying drawing drawn to scale, emphasis It is purport of the present utility model is shown.

As shown in figure 1, a kind of pump, the upper lid 2 including one and the lower bottom base 12 of one, described lower bottom base 12 has two The cantilever 1 stretching out, described cantilever 1 is connected with left bearing bearing 11 and right bearing bearing 8 respectively, described left bearing bearing 11 and the right side It is provided with left bearing and right bearing, axle 4 is supported by described left bearing and right bearing, and described lower bottom base 12 has in bearing spider 8 Have and described upper lid 2 corresponding lower covers 13, lower cover 13 is a part for lower bottom base 12, is integrated with lower bottom base 12, by described Lower cover 13 forms, with described upper lid 12, the chamber accommodating impeller 3, and described impeller 3 is fixed on described axle 4, a left side for described chamber, Right both sides are sealed by the first sealing ring 5, and the upper and lower opening of chamber forms water inlet and outlet, described upper lid 2 and institute The left and right two ends stating lower cover 13 are provided with axle sleeve 6, and described axle 4 is located in described axle sleeve 6, and axle sleeve 6 is close by the second sealing ring 10 Envelope.

In this utility model, upper lid 2 and lower bottom base 12 can be made of one piece using casting, and it is solid that upper lid 2 passes through bolt On lower bottom base 12, the part such as impeller 3, sealing member is respectively positioned within the chamber, so when needing to change impeller it is only necessary to unclamp Bolt, takes off lid 2, then the main parts size of pump all exposes outside in that context it may be convenient to complete the replacing of impeller, greatly reduces Maintenance time.

Elaborate a lot of details in order to fully understand this utility model in the above description.But above description It is only preferred embodiment of the present utility model, this utility model can be come with being much different from alternate manner described here Implement, therefore this utility model is not embodied as being limited by disclosed above.Any those skilled in the art exist simultaneously New to this practicality without departing from the methods and techniques content that the disclosure above under technical solutions of the utility model ambit, all can be utilized Type technical scheme makes many possible variations and modification, or the Equivalent embodiments being revised as equivalent variations.Every without departing from this The content of utility model technical scheme, any simply repaiies to made for any of the above embodiments according to technical spirit of the present utility model Change, equivalent variations and modification, all still fall within the range of technical solutions of the utility model protection.
