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 the entirety of one piece, and by the relative position of Pump and Electromotor, Submerged Motor Pumps is divided into pump type and lower suction type, the former pump upper, motor under, the main flow passage components of pump adopt impeller, stator, final stage stator and the pump housing; The latter's pump under, motor is upper, and the main flow passage components of pump adopt impeller and volute.
Current sewage/waste electrical submersible pump is all generally adopt single-stage lower suction type structure, and lift is lower, and by related standard requirements (as JB5118-2001), no matter watt level, lift is generally no more than 40 meters, also super only 50 meters that indivedual lift is higher.Its main cause is that the solid particle passing capacity of used final stage stator and stator is lower, makes multi-stage sewage sewage pump almost be difficult to realize, thus makes lift be difficult to improve.
Summary of the invention
For solving the defect existed in prior art, the invention provides a kind of pump top volute.The present invention, in order to replace final stage stator and the pump housing, enormously simplify structure, improves pump efficiency, for sewage/waste electrical submersible pump, also can improve solid matter passing capacity.
The present invention is achieved by the following technical programs:
A kind of pump top volute, forms primarily of housing; Housing is tubbiness and bottom opening, is volute room in it; There is protrusion housing side, and its top is provided with water outlet; Water outlet is connected to volute room by exhalant canal; Volute chamber interior walls is arc surface or spiral camber.
Described exhalant canal and volute chamber interior walls tangent and seamlessly transit.
Described case top is provided with 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 back shaft bearing bore in it.
Described spiral camber is Archimedian screw curved surface.
Described housing opening direction is contrary with water outlet opening direction.
Beneficial effect of the present invention is:
The present invention, in order to replace final stage stator and the pump housing, enormously simplify structure, improves pump efficiency, during for sewage/waste electrical submersible pump, also can improve solid matter passing capacity.

Fig. 1 is plan view of the present invention;
Fig. 2 is the A-A face sectional view of Fig. 1 or Fig. 3;
Fig. 3 is the C-C face sectional view of Fig. 2;
In figure: 1-housing, 11-base flange, 12-attachment hole, 13-drip irrigator fixed hole, 21-volute room, 22-boss, 23-back shaft bearing bore, 24-outlet passage, 25-water outlet.
Embodiment
Technological scheme of the present invention is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
A kind of pump top volute as shown in Figure 1 to Figure 3, forms primarily of housing 1; Housing 1 is tubbiness and bottom opening, is volute room 21 in it; There is protrusion housing 1 side, and its top is provided with water outlet 25; Water outlet 25 is connected to volute room 21 by exhalant canal 24; Volute room 21 inwall is arc surface or spiral camber.
Described exhalant canal 24 is tangent and seamlessly transit with volute room 21 inwall.
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 back shaft bearing bore 23 in it.
Described spiral camber is that Archimedian screw curved surface is for best.
Described housing 1 opening direction is contrary with water outlet 25 opening direction.
For reaching good fixed effect, the quantity of described drip irrigator fixed hole 13 and attachment hole 12 be 2 and more than.
Be installed on Submerged Motor Pumps top when the present invention uses, motor bearings is placed in the back shaft bearing bore 23 in boss 22, and impeller works in volute room 21, and the present invention then replaces final stage stator of the prior art and housing to carry out work.Submerged Motor Pumps work time, current enter into volute room 21 by below by impeller, due to volute room 21 and exhalant canal 24 tangent, therefore water flow energy unobstructed enter exhalant canal 24 from volute room 21.For the electric pump that part motor shaft is shorter, boss 22 can not be established.
When the present invention is applied to sewage dirt pump, described volute room 21 inwall is arc surface, and its effect is, facilitates processing, and do not affect the efficiency that current pass through, solid particle passing capacity is stronger simultaneously.And when the present invention is applied to clean waterpump, described volute room 21 inwall is generally spiral camber, and with Archimedian screw curved surface for the best.Because volute room 21 inwall is arc surface or spiral camber, meet the passage curve parameter request of volute, improve the efficiency that current pass through.
Simultaneously, because housing 1 itself is provided with water output connector fixed hole 13 and attachment hole 12, can realize and being fixedly connected with of other assemblies of Submerged Motor Pumps without the need to other specialized structure, save material, and overall structure is also simpler compared with the composite structure of final stage stator and housing, and the space that water supply flows through is large, so improve solid particle passing capacity to a great extent.
