Abstract
The utility model relates to a pipeline type rotary spraying pump which relates to the field of rotary spraying pumps and comprises a pump body of a vertical rotary spraying pump and a receiving pipe matched with the pump body of the vertical rotary spraying pump. The utility model is characterized in that the lower end of the axial extending section of the receiving pipe is directly inserted in an inner cavity of the pump body, besides, the receiving pipe and the corresponding position of the inner cavity of the pump body are respectively provided with a positioning key and a key groove which are matched mutually. After the utility model improves the prior art as above, the receiving pipe 5 can be conveniently disassembled and drawn out through the hoisting mode after only a mechanical seal component is separated from the pump body, besides, the mechanical seal component 6 can be conveniently replaced through the same operating mode. Therefore, the utility model has the advantages of simple structure, convenient maintenance and effectively reduced use cost. Besides, the structure is suitable for vertical rotary spraying pumps as well as horizontal rotary spraying pumps.
Description
Technical field
The utility model relates to the rotary-jet pump field, specifically is a kind of pipe type rotary-jet pump.
Background technique
As everyone knows, rotary-jet pump is suitable for containing the small flow of micro-solid particle fluid, high-lift conveying, because reliable performance, so be widely used in oil, chemical industry, no matter industries such as food are vertical.Still horizontal, its structure mainly comprises the pump housing, black box, receiving tube, work package etc., the rotary-jet pump of prior art is owing to the pump housing, black box, receiving tube is coupled to each other by flange etc. respectively and is one, a plurality of fixed card platforms are set on the receiving tube, when dismounting is keeped in repair or carried out the maintenance of parts, must dismantle lower pump body earlier like this, and then dismantle lower seal assembly etc. successively, can extract receiving tube out at last, install with opposite working specification when installing once more.This just need expend a large amount of time, the working efficiency when greatly reducing maintenance.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, pump structure is revolved in the spray of prior art be optimized transformation, and provide a kind of simple in structure, be convenient to safeguard, do not need earlier the pump housing and associated component to be dismantled when dismounting receiving tube or replacing black box, can effectively reduce the pipe type rotary-jet pump of user cost.
For achieving the above object, the utility model is achieved through the following technical solutions:
It is a kind of pipe type rotary-jet pump, comprise the pump housing of vertical rotary-jet pump and the receiving tube that matches, the lower end that it is characterized in that the receiving tube section of extending axially part directly is inlaid in the inner chamber of the pump housing, and the corresponding site of receiving tube and pump housing inner chamber is respectively arranged with the positioning key and the keyway of mutual coupling.
For better receiving tube being positioned, the top of receiving tube positioning key upper-end surface adjacent position with it is processed with the jump ring groove in the form of a ring, in the jump ring groove jump ring is set, and the upper-end surface of jump ring and the upper-end surface of the pump housing are positioned at same plane.
For strengthening the sealing between receiving tube and the pump housing inner chamber, the below of receiving tube positioning key lower end surface also is processed with o-ring groove, and the O RunddichtringO is set in the o-ring groove.
In addition, compact more for making equipment, the mechanical sealing assembly and the pump housing of suit directly link on the receiving tube of pump housing top, and fastening by both clamping bolts of correct positions setting, and the lower end surface of mechanical sealing assembly is fitted in the upper-end surface of jump ring.
After the utility model as above improves prior art, owing to only need mechanical sealing assembly with after the pump housing separates, receiving tube can be unloaded easily, extracts out, and can change mechanical sealing assembly easily, so brought beneficial effect be, simple in structure, be convenient to safeguard, can effectively reduce user cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model embodiment 1 structural representation.
Fig. 2: the utility model embodiment 2 structural representations.
Among the figure: 1 pump housing; The 2O RunddichtringO; 3 positioning keys; 4 jump rings; 5 receiving tubes; 6 mechanical sealing assemblies; 7 clamping bolts.
Embodiment
As shown in Figure 1, the utility model comprises the pump housing 1 of vertical rotary-jet pump and the receiving tube 5 that matches, the lower end that it is characterized in that receiving tube 5 sections of extending axially part directly is inlaid in the inner chamber of the pump housing 1, and the corresponding site of receiving tube 5 and the pump housing 1 inner chamber is respectively arranged with the positioning key 3 and the keyway of mutual coupling.
For better receiving tube 5 being positioned, the top of receiving tube 5 positioning key upper-end surfaces adjacent position with it is processed with the jump ring groove in the form of a ring, and jump ring 4 is set in the jump ring groove, and the upper-end surface of the upper-end surface of jump ring 4 and the pump housing 2 is positioned at same plane.
For strengthening the sealing between receiving tube 5 and the pump housing 1 inner chamber, the below of receiving tube 5 positioning key lower end surfaces also is processed with o-ring groove, and O RunddichtringO 2 is set in the o-ring groove.
In addition, compact more for making equipment, the mechanical sealing assembly 6 of suit directly links with the pump housing 1 on the receiving tube 5 of pump housing top, and fastening by both clamping bolts 7 of correct positions setting, and the lower end surface of mechanical sealing assembly 6 is fitted in the upper-end surface of jump ring 4.
After the utility model as above improves prior art, owing to only need mechanical sealing assembly with after the pump housing separates, can receiving tube 5 be unloaded easily, extract out by the mode of lifting, and can the identical operations mode change mechanical sealing assembly 6 easily, event has simple in structure, is convenient to safeguard, can effectively reduce the advantage of user cost, and this structure promptly is applicable to vertical rotary-jet pump, also is applicable to horizontal rotary-jet pump simultaneously as shown in Figure 2.
Claims (4)
