Abstract
The utility model relates to a Reel pump used for delivering liquid, which is composed of a pump body, twisted impellers, a pump shaft and a motor, wherein, the pump body forms a cone, a plurality of helical twisted impellers also form a similar cone; the outer end of the twisted impellers are with the inner wall of the pump body; the yawn is smaller than 1 mm; the conical angle of the inner wall of the conical pump body is 1-30 DEG. Compared with a water turbine pump in the same standard with the pump which is served as a water pump, when the power of the motor is same, the water quantity conveyed by the utility model can be increased by 20%; the pump reel has very low noise which can be lower than 15 db when runs. Hence, the reel pump is particularly suitable for the installation under indoor environment, and is an ideal water pump with low noise and high efficiency.
Description
The utility model relates to a kind of mechanical pump, specifically provides a kind of reel pump that can be used for carrying liquid.
Be used to carry the mechanical pump of liquid to mainly contain common pump kinds such as gear pump, vane pump, turbine pump, plunger pump at present.These mechanical pumps can satisfy the function of carrying liquid under the various conditions.But noise is all bigger when moving as common said pump kind, as the pump housing is done special processing, can reduce noise, and big but the volume of the pump housing becomes, its cost also will improve.
Reel pump also is a kind of common mechanical pump, but this class pump can only be used to carry the solid-liquid mixed serum that contains certain moisture, and can not be used for the very big liquid of transport flow, as light oil, water etc.
The purpose of this utility model provides a kind of reel pump that is used to carry liquid.
It is of the present utility model that to be used to carry the reel pump of liquid be to transform on common reel pump basis, and a kind of new-type design that proposes, this reel pump comprises that still critical pieces such as the pump housing, strand impeller, pump shaft, motor constitute, it is characterized in that pump housing inwall is a taper, multi-disc spirality strand impeller also is similar tapering, and strand impeller outer end is that close knot cooperates with pump housing inwall.When excesssive gap, liquid will be sprung back over the liquid entering hole place of the pump housing by this gap, so wasted power is bigger, for keeping the pump delivery outlet certain flow velocity be arranged, and can only improve the motor revolution, increase power consumption.Say that generally its gap should be preferably less than 0.3mm less than 1mm.The gap of above-mentioned strand impeller outer end and pump housing inwall is right in the installation of strand impeller, determines by the axial position of adjustment pump shaft in the pump housing.The taper pump housing of the utility model reel pump, export the liquid stream of enough pressure in the time that wheel rotation will being helped, when cone angle increases, the respective cylinder delivery pressure increases, but will reduce the flow of liquid, the size of angle of taper should be carried out comprehensive Design by pump housing output power, flow and lift, and it is more suitable to be generally 1～30 ° of angle, can obtain preferable comprehensive effect when taper angle is 3～15 °.Below by accompanying drawing reel pump structure of the present utility model is given to illustrate further.
Accompanying drawing 1 is the structural profile schematic representation of the utility model reel pump;
Accompanying drawing 2 is the schematic representation of strand impeller and the tapered structural design scheme of the pump housing in the reel pump of accompanying drawing 1.
1. pump housings in the accompanying drawing; 2. strand impeller; 3. pump shaft; 4. bobbin; 5. bearing; 6. motor; 7. coupling; 8. seal ring; 9. the pump housing enters the mouth; 10. pump housing outlet; α. pump housing taper angle.
The reel pump of structure shown in attached Fig. 1 and 2 can be an embodiment of the present utility model.This reel pump is assembled by the pump housing (1), strand impeller (2), pump shaft (3), motor (6), bearing (5).This strand impeller (2) can be one with pump shaft (3) or has welded together after the processing respectively again, and a bearing (5) is positioned on the pump housing (1) bobbin (4), and another is positioned at pump housing upper end, is used to install pump shaft (3).Fixing between the pump housing (1) upper end and electric machine stand with the flange plate binding, and pass through coupling (7) with motor shaft and pump shaft (5) binding, seal ring (8) guarantees that the sealing of the pump housing (1) and pump shaft (3) is encased inside.As an instantiation, the pump housing (1) inwall conicity angles alpha is 7 °, and strand impeller (2) also is 7 ° of similar taperings, when pump shaft (5) is installed, adjusts the axial position of pump shaft (5), and making strand impeller (2) and the pump housing (1) inwall gap is 0.2mm.
The processing of the utility model reel pump and assembling all can be carried out with reference to routine techniques.
Make supply-water pump with above-mentioned reel pump of the present utility model and compare with the same specification turbine pump, identical at power of motor The time, carry the water yield can improve 20%, and the noise of reel pump is very low during operation, can reach below 15 decibels. Cause This, this reel pump suits to install under indoor environment especially, is a kind of desirable low noise efficient water pump or oil transportation Pump.
Claims (4)
1. reel pump that is used to carry liquid, be made of the pump housing, strand impeller, pump shaft, motor, it is characterized in that pump housing inwall is a taper, multi-disc spirality strand impeller also is similar tapering, and strand impeller outer end is that close knot cooperates with pump housing inwall, and its gap should be less than 1mm.
2. according to the described reel pump of claim 1, the gap that it is characterized in that twisting impeller outer end and pump housing inwall should be less than 0.3mm.
3. according to the described reel pump of claim 1, the inwall taper angle that it is characterized in that the taper pump housing (1) is 1～30 °.
4. according to the described reel pump of claim 1, the inwall taper angle that it is characterized in that the pump housing (1) is 3～15 °.
