Technical field:
The utility model high-lift multi-stage centrifugal pump relates to first part that high-lift multi-stage centrifugal pump sucks fluid, i.e. suction casing with suction casing.
Background technique:
The stationary part of high-lift multi-stage centrifugal pump is formed by entering end cap, suction casing, stage casing, Spit Section and bearing part etc.; Intake end cover, suction casing, stage casing and Spit Section system are strained and fixed by turnbuckle, junction plane adopts " O " type rubber ring to seal, two end axles envelope adopts soft packing, and introduces in addition water seal of water seal water, to prevent that ambient air from entering in the pump and big quantity of fluid oozes out.
Suction casing in the high-lift multi-stage centrifugal pump stationary part is first part that sucks fluid, for guaranteeing pump performance, and installation, the connection performance of suction casing in stationary part, suction casing there are some specific structural requirements, should do specific design with suction casing high-lift multi-stage centrifugal pump.
Summary of the invention:
The purpose of this utility model provides a kind of high-lift multi-stage centrifugal pump suction casing, and design has dewatering outlet, fixed hole, lifting eye, support plate, suction flange, suction port, return pipe interface, handle hole, pre-tieholen, fitting surface, standby boss, process cavity, puts and press mouth and interface etc. on suction casing.
A kind of high-lift multi-stage centrifugal pump suction casing is characterized in that in suction casing (1) bottom dewatering outlet (2) being arranged, and has fixed hole (2) and lifting eye (4) on the support plate (5) of bottom; Suction casing (1) has suction flange (6), and suction port (7) is arranged in the suction flange (6); Return pipe interface (8), two handle holes (9), some pre-tieholens (10), fitting surface (11), standby boss (12), process cavity (13) are arranged on suction casing (1); Suction casing (1) top is put and is pressed mouthful (14), end face that interface (15) is arranged.
The utility model high-lift multi-stage centrifugal pump suction casing can be used for producing the multistage centrifugal pump up to 1000 meters lifts.
The dewatering outlet is arranged at the bottom at suction casing, so that discharge the ponding in the suction casing; It is bearing poweies of strengthening the pump housing that two support plates, purpose are arranged in the suction casing bottom, and two support plates are symmetrical in the suction casing center line, respectively have a fixed hole on these two support plates, by bolt the pump housing are fixed on the base; On these two support plates, also have a lifting eye, use when being used for suspending pump; Suction flange is arranged on suction casing, install bolt in the bolt hole of suction flange, be connected with outside intake line, at the suction flange inner ring suction port is arranged, suction port is used for sucking fluid; On the suction port wall behind the suction flange, have the return pipe interface, connect the return pipe parts.
In the suction casing both sides handle hole is arranged respectively, usefulness when being used for the single suction casing of handling can be adorned bolt in handle hole, but by bolt handling suction casing.
Some pre-tieholens are arranged on suction casing, in these pre-tieholens, install turnbuckle, pump is strained; In pre-tieholen, have auxiliary hole, so that reduce manufacture cost.
One circle fitting surface is arranged on suction casing, match, so that the chopped-off head intermediate clapboard is installed with the chopped-off head intermediate clapboard.
Standby boss is arranged on suction casing, can on standby boss, open standby handle hole.
Put the pressure mouth at the suction casing top, so that regulate the suction casing internal pressure.
The interface that on suction casing, matches with intake end cover in addition.
This high-lift multi-stage centrifugal pump is a compact structure with the suction casing advantage, and function is complete, lifting is installed conveniently.
