Abstract
Provided is a high-lift multistage centrifugal pump, comprising an inner operation chamber which is formed by clamping an absorption section, guide vanes, a middle section and a secondary absorption section via a tensioning bolt. The center of the inner operation chamber is provided with a rotating shaft penetrating from the absorption section to the secondary absorption section. The plurality of guide vanes are installed at the outer periphery of the rotating shaft. The part between the middle section and the secondary absorption section is a water outlet section. The outer side of the inner operation chamber is connected with a seal flushing pipe assembly. The utility model has the beneficial effects that a stator part of the operation region is mainly composed of the absorption section, the middle section, an output section, the guide vanes and so on, simplifying the integral structure, enabling a rotor to be supported stably and reliably, making the operation convenient, facilitating efficiency enhancement and prolonging the service lifetime; and the high-lift multistage centrifugal pump is suitable for conveying clear water for coal mines and neutral mine water with the content of solid particles less than 1.5%, and is suitable for water supply and discharge for coal mines, factories and cities.
Description
Technical field
The utility model relates to a kind of centrifugal pump, relates in particular to a kind of high-lift multi-stage centrifugal pump.
Background technique
Centrifugal pump generally is made up of main four parts of stator, rotor, bearing and axle envelope, centrifugal pump is used for the colliery carries clear water and solid content to be not more than 1.5% neutral mine water, because existing its structure of centrifugal pump should be comparatively simple, if volume is excessive or complicatedly all can bring certain difficulty to maintenance, in addition, the cavitation resistive property of a lot of pump housings is relatively poor, and its flow, pressure, rotating speed are stable inadequately, therefore then need centrifugal pump structure is carried out certain improvement.
The model utility content
At above defective, the purpose of this utility model provide a kind of help simplifying overall structure, rotor supports steadily reliable, easy to operate, help the high-lift multi-stage centrifugal pump of raising the efficiency, increasing the service life, to solve many deficiencies of prior art.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of high-lift multi-stage centrifugal pump, comprise by suction casing, stator, stage casing part, secondary suction casing partly by turnbuckle pinched composition work inner chamber, this work lumen centers position is provided with runs through the rotating shaft of suction casing to secondary suction casing part, the some stators of the peripheral installation of described rotating shaft, between stage casing part and secondary suction casing part is the water exit end part, and the described work inner chamber outside connects sealflushes the pipe assembly.
The beneficial effect of high-lift multi-stage centrifugal pump described in the utility model is: the stationary part of working zone mainly is made up of suction casing, stage casing, Spit Section and stator etc., simplified overall structure, rotor supports steadily reliable, easy to operate, help raising the efficiency, increasing the service life; Can be applicable to fully that colliery conveying clear water and solid content are not more than 1.5% neutral mine water, be applicable to mine, factory and urban water supply and sewerage usefulness.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the structural representation of the described high-lift multi-stage centrifugal pump of the utility model embodiment.
Among the figure:
1, pin elastic coupling flexible coupling; 2, rotating shaft; 3, bearing part; 4, Gland; 5, suction casing; 6, stator; 7, stage casing part; 8, final stage stator; 9, water exit end part; 10, orifice sleeve; 11, turnbuckle; 12, secondary suction casing part; 13, sealflush the pipe assembly.
Embodiment
As shown in Figure 1, high-lift multi-stage centrifugal pump described in the utility model, its inside mainly comprises by suction casing 5, stator 6, stage casing part 7, secondary suction casing part 12 is by the work inner chamber of turnbuckle 11 pinched compositions, this work lumen centers position is provided with runs through the rotating shaft that have bearing part 32 of suction casing 5 to secondary suction casing part 12, the some stators 6 of described rotating shaft 2 peripheral installations make its work by axial region power is passed to impeller, be positioned at stage casing part 7 inboards and be provided with final stage stator 8, between stage casing part 7 and secondary suction casing part 12 is water exit end part 9, and rotating shaft 2 outsides of these water exit end part 9 positions are provided with orifice sleeve 10; The end that described rotating shaft 2 is connected with motor is provided with pin elastic coupling flexible coupling 1, and rotating shaft 2 outsides that are positioned at suction casing 5 inboards are provided with Gland 4; The described work inner chamber outside connects sealflushes pipe assembly 13.
