Abstract
A compound pump comprises a pump body, a pump cover, a bearing seat, a pump spindle, a main centrifugal impeller, a hand pump, a water inlet pipe and a water outlet pipe. The technical key points lie in that: the pump body outside the pump cover is connected to the bearing seat through bolts; the pump spindle is arranged in the axle holes of both the pump cover and the bearing seat; the pump spindle at the outer end of the bearing seat is provided with a triangular belt pulley; the main centrifugal impeller in opposition to the water inlet of the pump body is arranged on the pump spindle inside the pump body in a sleeved manner; an axial flow auxiliary impeller is also arranged on the pump spindle at the water inlet of the pump body in the sleeved manner; the water inlet of the pump body is connected to the water inlet pipe with the hand pump; the water inlet pipe is connected to an inflowing water elbow; the water outlet pipe is arranged at the upper part of the pump body. The compound pump has the characteristics of great flow of an axial flow pump and high pump lift of the centrifugal pump; meanwhile, the compound pump also has the characteristics of saving electricity, oil and labor, achieving a simple structure, convenient installation and low maintenance cost, and especially being convenient to realize remolding and having a very wide application range.
Description
Technical field
The present invention relates to a kind of water pump, particularly the compound pump that combines of a kind of axial flow pump and centrifugal water pump.
Background technique
As everyone knows, according to the classification of centrifugal water pump pressure, be divided into low pressure pump and high-pressure service pump.According to textural classification, be divided into single-stage (impeller) and multistage pump (a plurality of impeller serial)., complex structure large for the multi-stage water pump volume, consumptive material are high, machining accuracy and assembly precision require highly, must strengthen cost of production.A plurality of main impellers coaxially connect simultaneously, and flow path is not smooth, affects pump efficiency.
Summary of the invention
The purpose of this invention is to provide a kind of compound pump, do not changing under former single leaf human relations centrifugal water pump structure prerequisite, tightening nut before main impeller is pulled down, be replaced with sub-propeller, make improved water pump have the large and much higher level of the lift water pump characteristics of flow, but little, simple in structure than multi-stage water pump volume in the past, consumptive material is low, machining accuracy and the assembly precision requirement all low.
The technical solution adopted in the present invention is: this compound pump comprises the pump housing, pump cover, bearing support, pump shaft, centrifugal main impeller, hand pump, intake pipe and outlet pipe, its technological points is: be bolted bearing support on the pump housing in the described pump cover outside, in the axis hole of pump cover and bearing support, be provided with pump shaft, be provided with V-belt wheel on the pump shaft of bearing support outer end; On pump shaft in the pump housing, be set with the centrifugal main impeller relative with pump housing water intake, on the pump shaft of pump housing water inlet, also be set with an axial flow sub-propeller, the intake pipe of this pump housing water intake connecting band hand pump, intake pipe connect the water inlet elbow; Described pump housing top is provided with outlet pipe.
Described axial flow sub-propeller adopts helix structure.
The number of blade of described axial flow sub-propeller is the 3-6 sheet.
Advantage and good effect that the present invention has are:
1. do not changing other mechanism of raw water pump, tightening nut before main impeller is pulled down, be replaced with sub-propeller (sub-propeller still plays the effect of fastening main impeller), so neither change structure and the production technology of former unit water pump, reached the effect of multi-stage water pump, thereby improved the water pump volumetric efficiency, shown through laboratory data, can increase capacity and water pump total head 15%-20%;
2. install the axial flow sub-propeller additional and adopt sped structure, make this novel existing axial-flow pump flow that the characteristics that centrifugal pump lift is high be arranged greatly again;
3. economize on electricity, fuel-economizing, saving labour;
Simple in structure, easy for installation, maintenance cost is low;
5. particularly be convenient to realize transformation, application area is very wide.
The accompanying drawing explanation
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is sectional structure schematic diagram of the present invention.
Sequence number explanation in figure: 1 V-belt wheel, 2 bearing caps, 3 bearings, 4 pump shafts, 5 lubricating cups, 6 bearing supports, 7 glands, 8 High-pressure oil sealings, 9 conduit pipes, 10 hand pumps, 11 packings, 12 axle sleeves, 13 pump covers, 14 pump cover seal rubber pads, 15 pump housings, 16 centrifugal main impellers, 17 control ring seal rings, 18 water intake seal rubber pads, 19 intake pipes, 20 axial flow sub-propellers, 21 water inlet elbows.
