Abstract
The invention discloses a pump top volute casing mainly comprising a casing. The casing is barrel-shaped and provided with an opening at the bottom and a volute casing chamber inside. The lateral side of the casing is provided with a projection and the top thereof is provided with a water outlet. The water outlet is connected to the volute casing chamber through a water outlet passage, and the inner wall of the volute casing chamber is an arc-shaped surface or a spiral curved surface. The water outlet passage is tangent with the inner wall of the volute casing chamber and is in smooth transition. The top of the casing is provided with more than two water outlet joint fixing holes. The casing is provided with more than two connecting holes, and a bottom flange is arranged on the periphery of the bottom of the casing. An outward boss is arranged on the top of the casing, and a bearing support hole is reserved in the boss. The spiral curved surface is an Archimedes spiral curved surface. The openings of the casing and the water outlet are opposite in direction. The pump top volute casing can substitute for final-stage guide vanes and a pump body, is used for a sewage and waste submersible electric pump and can improve solid passing capability, the structure is simplified greatly, and pump efficiency is improved.
Description
Technical field
The present invention relates to water pump, specifically a kind of pump top volute.
Background technique
Submerged Motor Pumps is that Pump and Electromotor organically combines an integral body at one, press the relative position of Pump and Electromotor, and Submerged Motor Pumps is divided into pump formula and lower suction type, and the former pump is upper, and motor is lower, main flow passage components employing impeller, stator, final stage stator and the pump housing of pump; Latter's pump is lower, and motor is upper, and the main flow passage components of pump adopt impeller and volute.
Sewage/waste electrical submersible pump generally all is to adopt single-stage lower suction type structure at present, and lift is lower, and by related standard requirements (such as JB5118-2001), no matter watt level, lift generally is no more than 40 meters, and what indivedual lifts were higher also surpasses only 50 meters.Its main cause is that the solid particle passing capacity of employed final stage stator and stator is lower, so that the multi-stage sewage sewage pump almost is difficult to realization, thereby makes lift be difficult to improve.
Summary of the invention
For solving the defective that exists in the prior art, the invention provides a kind of pump top volute.The present invention simplifies the structure greatly in order to replace final stage stator and the pump housing, has improved pump efficiency, is used for sewage/waste electrical submersible pump, also can improve the solid matter passing capacity.
The present invention is achieved by the following technical programs:
A kind of pump top volute mainly is comprised of housing; Housing is tubbiness and bottom opening, is the volute chamber in it; There is protrusion the housing side, and its top is provided with water outlet; Water outlet is connected in the volute chamber by exhalant canal; The volute chamber interior walls is arc surface or spiral camber.
Described exhalant canal and volute chamber interior walls are tangent and seamlessly transit.
Described case top is provided with the water output connector fixed hole.
Described housing is provided with attachment hole, and bottom periphery is provided with base flange.
The quantity of described drip irrigator fixed hole and attachment hole be 2 and more than.
Described case top has an outside boss, is provided with the spring bearing hole in it.
Described spiral camber is the Archimedian screw curved surface.
Described housing opening direction is opposite with the water outlet opening direction.
Beneficial effect of the present invention is:
The present invention simplifies the structure greatly in order to replace final stage stator and the pump housing, has improved pump efficiency, when being used for sewage/waste electrical submersible pump, also can improve the solid matter passing capacity.

Fig. 3 is the C-C face sectional view of Fig. 2;
Among the figure: 1-housing, 11-base flange, 12-attachment hole, 13-drip irrigator fixed hole, 21-volute chamber, 22-boss, 23-spring bearing hole, 24-outlet passage, 25-water outlet.
Embodiment
Further describe technological scheme of the present invention below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
A kind of pump top volute as shown in Figure 1 to Figure 3 mainly is comprised of housing 1; Housing 1 is tubbiness and bottom opening, is volute chamber 21 in it; There is protrusion housing 1 side, and its top is provided with water outlet 25; Water outlet 25 is connected in volute chamber 21 by exhalant canal 24; Volute chamber 21 inwalls are arc surface or spiral camber.
Described exhalant canal 24 is tangent and seamlessly transit with volute chamber 21 inwalls.
Described housing 1 top is provided with water output connector fixed hole 13.
Described housing 1 is provided with attachment hole 12, and bottom periphery is provided with base flange 11.
One outside boss 22 is arranged at described housing 1 top, is provided with spring bearing hole 23 in it.
Described spiral camber is that the Archimedian screw curved surface is for best.
Described housing 1 opening direction is opposite with water outlet 25 opening directions.
For reaching preferably fixed effect, the quantity of described drip irrigator fixed hole 13 and attachment hole 12 be 2 and more than.
Be installed on the Submerged Motor Pumps top when the present invention uses, motor bearings places the spring bearing hole 23 in the boss 22, and impeller works in the volute chamber 21, and the present invention then replaces final stage stator of the prior art and housing to carry out work.In Submerged Motor Pumps when work,, current enter into volute chamber 21 by the below by impeller because volute chamber 21 and exhalant canal 24 are tangent, therefore water flow energy unobstructed enter exhalant canal 24 from volute chamber 21.For the shorter electric pump of part motor shaft, can not establish boss 22.
When the present invention was applied to the sewage dirt pump, described volute chamber 21 inwalls were arc surface, and its effect is, has made things convenient for processing, did not affect the efficient that current pass through simultaneously, and the solid particle passing capacity is stronger.And when the present invention was applied to clean waterpump, described volute chamber 21 inwalls were generally spiral camber, and take the Archimedian screw curved surface as best.Because volute chamber 21 inwalls are arc surface or spiral camber, meet the passage curve parameter request of volute, have improved the efficient that current pass through.
Simultaneously, because housing 1 itself is provided with water output connector fixed hole 13 and attachment hole 12, need not other specialized structure can realize and being fixedly connected with of other assemblies of Submerged Motor Pumps, saved material, and overall structure also the composite structure than final stage stator and housing is simpler, and the space that water supply stream passes through is large, so improved to a great extent the solid particle passing capacity.
