[technical field]
The utility model relates to pump motor cooling technology field, specifically a kind of relevant pipeline mounted pump that cooling medium is optimized the necessary electromotor electromagnetism that uses water as.
[background technique]
K series horizontal centrifugal pump is suitable for living water, industrial water supply, air conditioner cold-heat water circulation system, fire hydrant or the automatic sprinkler fire-extinguishing system etc. of all kinds of buildings in town and country, is widely used.Its adapted motor generally adopts Y series two-pole machine, rotating speed higher.Mainly by motor top radiation fan, the noise that radiation fan produces when running up is bigger for the motor radiating amount of sending out, and influences the normal life that surrounding environment upsets people.Because noise source on the fan of heat radiation, so set about from motor, is designed with water pump supportingly, the motor special for water pump that noise is low is necessary.
[summary of the invention]
The purpose of this utility model is to overcome the deficiencies in the prior art, to make cooling medium reduction electric machine temperature rise with air originally and change water reduction electric machine temperature rise into, cooling medium is different in itself, the structure of motor and water pump and the internal electromagnetic design of motor are improved, and a kind of relevant pipeline mounted pump that uses water as cooling medium optimization necessary electromotor electromagnetism of design.
For achieving the above object, design a kind of relevant pipeline mounted pump that cooling medium is optimized the necessary electromotor electromagnetism that uses water as, comprise by the pump housing, impeller, pump shaft, outer cover, motor, base etc., wherein the hyperbaric chamber at water outlet place bottom is provided with at least more than one water inlet, water inlet one end is located at the hyperbaric chamber bottom, the lower cover flange of connecting cap between the motor and the pump housing and motor, the water inlet the other end is located in the motor cavity as intake tunnel, on the upper right sidewall of low-pressure cavity, be provided with at least more than one osculum, osculum one end is located in the low-pressure cavity, by way of motor lower cover flange, the osculum the other end connects motor top collector pipe as exhalant canal.Described motor is 24 for the stator core slot number, and the wire gauge radical is the low noise motor of 2-0.71.
The utility model is compared with prior art, can improve the motor grooved, has improved electric efficiency, and can save the motor manufactured materials, has reduced motor noise, has improved working environment, is a kind of environmentally friendly machine.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1,1 is the pump housing; 2 is impeller; 3 is pump shaft; 4 is water intake; 5 is water outlet; 6 is the water inlet; 7 is osculum; 8 is hyperbaric chamber; 9 is low-pressure cavity; 10 is connecting cap; 11 is motor lower cover flange; 12 is motor top collector pipe; 13 is the stainless steel outer cover; 14 is the cavity that stainless steel outer cover and motor are asked; 15 is motor; 16 is base.
[embodiment]
Below in conjunction with accompanying drawing the utility model is further described, the utility model is still more clearly concerning those skilled in the art.
Referring to accompanying drawing 1, bore a water inlet (6) in hyperbaric chamber (8) bottom that the water outlet (5) of the horizontal centrifugal pump housing (1) of K series is located, the upper strata of the connecting cap between the motor and the pump housing (10), the upper strata of lower cover flange (11) of passing through motor again is until motor cavity (14), the intake tunnel of the motor cooling water that to form a diameter be 5-8mm, an osculum (7) bores in the lower floor of the connecting cap of locating in the low-pressure cavity (9) at impeller (2) back (10) again, lower floor by way of motor lower cover flange (11), be connected with motor top collector pipe (12) again, form water channel.
Water pump is the zone of high pressure at the water outlet place of when work pump housing, and is low pressure area at pump housing place, impeller back.Entire pump is installed and fixed by base (16), during work, rotate by motor (15) impeller (2) that pump shaft (3) one ends connect, water is introduced in the pump chamber from water intake (4), the import and export differential water pressures that produces when utilizing water pump self running again, in the cavity (14) between a small amount of water outlet introducing motor (15) and the stainless steel outer cover, the motor cooling water is in the water inlet passage enters motor cavity between motor and the stainless steel cage (13), again from the collector pipe (12) on motor top, entering low pressure area by the osculum passage rings off with other water, thereby distribute heat when taking away machine operation, form a cooling motor, reduce the water circulation system of electric machine temperature rise, so just reached the purpose that reduces electric machine temperature rise, make motor and pump operation part as keeping normal operating temperature eventually, and removed fan, made noise also fall.
Because the cooling medium of motor becomes water from air, the internal electromagnetic design proposal of motor also changes, and has done variation on the size of electromagnetic wire and silicon steel plate.The technical data of general Y132S1-2 motor and low noise motor is different fully, but two kinds of motor output powers are just the same.Be connected water pump institute work, i.e. flow 12.5m with same KLD40-5.5 water pump
3/ h, the noise that support is produced during lift 50m differs greatly, and reaches low noise requirement fully.The stator iron core external diameter of low noise motor is reduced to 143mm from original 210mm, the stator iron core internal diameter expands 143mm to from original 116mm, the stator core slot number is reduced to present 24 by original 30, the wire gauge radical becomes 2-0.71 by 1-0.9 or 1-0.95, every line of rabbet joint number increases to 47 by 44, and way in parallel becomes 2 the tunnel by original 1 the tunnel, simultaneously the motor manufacturing with material on, also accomplish to save material, Y132S1-2 reaches 5.7 kilograms with copper.And only 3.8 kilograms of new low noise motor materials, every nearly 2kg of motor joint copper.
