Abstract
The utility model relates to a vertical core-loosing type mixed flow pump, comprising a water-in horn, wherein two sides of the upper end of the water-in horn are connected with two sides of the lower end of a guide blade outer tube and two sides of the upper end of the guide blade outer tube are connected with a pump seat by a bent tube; the upper end of the pump seat is connected with an electric machine seat of a seal device; a coupler is mounted on the electric machine seat; a runner chamber and a guide blade body connected with the runner chamber are arranged below the pump seat and in the bent tube and the guide blade outer tube; a guide bearing is mounted in the guide blade body to be connected with the guide blade body by a bolt and a sleeve is arranged above the guide blade body; a diversion shell capable of playing the role of diversion is mounted on a baffle on the pump seat and the coupler is mounted above the pump axle and its lower end is connected with an impeller. The beneficial effects are that: when in need of repair, it is only necessary to drawing the rotor parts from the water pump outer shell to greatly reduce the work load; when mounting, the water pump outer shell and the rotor parts are independently mounted and firstly the outer shell is fixed and then the rotor parts are inserted into the outer shell.
Description
Technical field
The utility model relates to vertical mixed flow pump, relates in particular to this vertical mixed flow pump structure.
Background technique
As seen from Figure 1: existing vertical mixed flow pump comprises: water inlet loudspeaker 1, impeller 2, diffuser 3, guide bearing 4, pump shaft 6, bend pipe 5, pump seat 7, seal arrangement 8, coupling 10 and motor cabinet 9 are formed.The water inlet loudspeaker are connected by bolt with diffuser, and between diffuser and the bend pipe, all be to link to each other by bolt between bend pipe and the pump seat, all parts all are to be rigidly connected into an integral body, if inner body goes wrong, have only whole water pump disintegration could be keeped in repair.
But the problem that this structure exists is:
When the first, keeping in repair, need earlier the water pump and the connecting bolt on basis are dismantled, remove the mouth of a river and external steel pipe again, afterwards whole water pump is hung out maintenance.Water pump itself is owing to long-play, and easily damaged parts needs periodic replacement, but water pump body generally can be not defective in quality, but needs above-mentioned numerous and diverse process in order to keep in repair, and brings great inconvenience for user's maintenance.
When the second, installing, the water pump integral installation, general mixed flow pump all has weight more than 5 tons, like this scene when mounted because weight is excessive, on-the-spot must the big lifting appliance of outfit.
Summary of the invention
The utility model solves has provided a kind of vertical Drawing-Core mixed flow pump, is intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: the water inlet loudspeaker; The both sides, upper end of described water inlet loudspeaker connect the both sides, lower end of a stator urceolus; The both sides, upper end of stator urceolus link to each other with pump seat by bend pipe; The upper end of pump seat joins by seal arrangement and motor cabinet; On motor cabinet, settle a coupling; Under pump seat, in bend pipe and the stator urceolus, comprise: runner envelope and the diffuser that is connected runner envelope; Guide bearing is installed in the diffuser with it and connects by bolt, and sleeve pipe is positioned at the diffuser top, and the blower inlet casing that plays guide functions is installed on the baffle plate on the pump seat, and coupling is installed in the pump shaft top, and the lower end links to each other with impeller.
Compared with prior art, the beneficial effects of the utility model are: when needing repairing, do not need to dismantle water pump and the bolt that the basis is connected, also need not to dismantle exit of pump and external pipeline, only rotor part need be extracted out from the pump shell body and got final product, reduce workload greatly; During installation, pump shell body and rotor part are installed separately, and earlier frame are installed and fixed, and rotor part are inserted in the frame to get final product again.
Description of drawings
Fig. 1 is a vertical mixed flow pump structural representation in the prior art;
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: water inlet loudspeaker 101; The both sides, upper end of described water inlet loudspeaker 101 connect the both sides, lower end of a stator urceolus 1013; The both sides, upper end of stator urceolus 1013 link to each other with pump seat 107 by bend pipe 105; The upper end of pump seat 107 joins by seal arrangement 108 and motor cabinet 109; On motor cabinet 109, settle a coupling 1010; In pump seat 107 times, bend pipe 105 and stator urceolus 1013, comprise: runner envelope 1014 and the diffuser 103 that is connected runner envelope 1014; Guide bearing 104 is installed in the diffuser 103 and connects by bolt with it, sleeve pipe 1011 is positioned at diffuser 103 tops, the blower inlet casing 1012 that plays guide functions is installed on the baffle plate on the pump seat 107, and coupling 1010 is installed in pump shaft 106 tops, and the lower end links to each other with impeller 102.
Water inlet loudspeaker in the utility model, stator urceolus, bend pipe and pump seat are formed the outer shell component of water pump, impeller, guide bearing, and pump shaft, diffuser, sleeve pipe, blower inlet casing and runner envelope are formed rotor part.
Water pump is divided into frame to the utility model and rotor part two-part are formed, wherein frame is structural member, between pass through bolt, frame mainly is subjected to the water flow pressure effect in use, so before installing, all carry out the hydrostatic test, the part that meets the demands just allows assembling, so the working life of frame is very long, seldom Accident due to quality can take place; Rotor part is the core component of water pump, directly influence the quality of pump performance, guide bearing is an easily damaged parts simultaneously, move needed to change once in about 2 years, when needs are changed, only rotor part need be got final product from the frame extraction, frame part and bend pipe and rising pipe all need not dismounting, very convenient, and the weight of rotor part only accounts for about 25% of whole water pump, lifts by crane so and install all to be easy to.
Guarantee that so how it is exactly crucial that rotor part is extracted out from frame, water pump is under water for a long time in other words, how to guarantee between rotor part and the frame fitting surface stainless dead?
At first, for rotor part is extracted out smoothly, just need leave enough gaps between two fitting surfaces, again can not be excessive otherwise can influence the water pump utilization efficiency in the gap, advances overtesting fitting surface tolerance and think that to select H8/d7 comparatively suitable; Afterwards, the problem of rustiness between the fitting surface is selected for use to add at fitting surface and is allowed some leeway man-hour, and the Cr (chromium) of spraying 0.05-0.08mm on fitting surface is feasible fully through this scheme of long-time evidence afterwards.
