Abstract
The invention discloses a double-head circulating water pump. A water pump body is respectively installed on shafts at two ends of a double-head electric motor to form the double-head circulating water pump. According to the pump, the electric motor is used for driving the two water pump bodies to operate, the space size of a water source heat pump outdoor machine is reduced, a unit is compact and reasonable, and water pump bodies can be installed inside conveniently. Water pump bodies are arranged at two ends of the electric motor, so that the probability that the electric motor is burnt down due to long-time cavitation phenomena of a single-head water pump is reduced.
Description
Technical field
The present invention relates to a kind of double end circulating water pump.
Background technique
Headwaters heat pump in use, the circulation of the chilled water of indoor and outdoor side and cooling water all is equipped with circulating water pump, is referred to as chilled water pump and cooling waterpump respectively.If consider that project installation is simple and convenient; It is built-in that manufacturer will consider the water pump outdoor unit; Though such design proposal has made things convenient for project installation, owing to need in the outer machine of water resource heat pump two circulating water pump are installed, such result is the size that has not only strengthened the water resource heat pump outdoor unit; Be unfavorable for unit compactness principle easily, also increased the weight of outer unit in addition.
Traditional way is at present, and one in circulating water pump is built-in, and one external; Perhaps two water pumps are all external.Such design proposal though can reduce the size of outer machine, has increased the project installation amount.
Summary of the invention
The object of the invention provides a kind of double end circulating water pump.
The present invention adopts following technological scheme for realizing above-mentioned purpose:
A kind of double end circulating water pump forms on the axle at double end motor two ends, a water pump being housed respectively.
The present invention adopts two pump operations of a motor band, has reduced the bulk of water resource heat pump outdoor unit, makes unit compact and reasonable more, makes things convenient for water pump built-in.Because motor two ends are water pump body, reduced that long-time cavitation phenomenon takes place the single head water pump and the possibility (indoor chilled water circuit and outdoor chilled(cooling) water return (CWR) take place simultaneously on the probability theory of cavitation phenomenon and should lack 50% than the possibility that cavitation phenomenon takes place in single loop) of burning motor.
Description of drawings
Fig. 1 is the structural representation of double end circulating water pump of the present invention, and wherein 1,2 is the pump housing, and 3 is the double end motor.
Embodiment
As shown in Figure 1, a kind of double end circulating water pump comprises double end motor 3, the pump housing 1 and the pump housing 2.
During motor work, left and right sides water pump 1,2 turns round simultaneously, has so just satisfied indoor chilled water circulation and outdoor cooling water circuit purpose.When design selection, the flow of pump and lift should satisfy indoor chilled water and two big values of circulation of outdoor cooling water.
Claims (1)
1. double end circulating water pump is characterized in that: it forms on the axle at double end motor two ends, respectively adorning a water pump.
