Description

A kind of recycle pump
Technical field
The utility model relates to a kind of pump, relates in particular to a kind of recycle pump.
Background technique
In people's life, use recycle pump to be used for the various circuit occasions that need usually, such as the hot water circuit in family's floor heating, boiler circulation.Recycle pump is many to be used as power source with AC induction motor; On its basis, adopt tap to carry out manual gear speed regulating control and the control AC induction motor is many; Its inconvenience is to adopt AC induction motor energy consumption height, secondly can not regulate power automatically according to the load size, can not control by constant pressure and flow once more; And can not electrodeless variable-speed, in use have inconvenience more.And universal shielding recycle pump or title pipeline mounted pump have been widely used in building heatings such as family, office, hotel mansion and have supplied water, and industrial cool cycles etc.But water pump adopts the constant traditional method of operation of rotating speed, when in the pipeline during overpressure, can cause the abnormal sound of water pipe, can only solve through manual tune, and cause a large amount of energy wastes, can not satisfy energy-conservation needs.
Summary of the invention
The utility model discloses a kind of recycle pump, high in order to solve the existing technology energy consumption, can not regulate power automatically according to the load size, can not constant pressure and flow control, and can not electrodeless variable-speed etc. problem.
The technical solution of the utility model is: a kind of recycle pump; Comprise the circulation pump housing and control mechanism; It is characterized in that: the described circulation pump housing is by dc brushless motor, impeller, the pump housing; Motor housing is formed, and control structure is no sensor frequency-variable controller group, and no sensor frequency-variable controller links to each other with dc brushless motor.
Further, the axle on the described dc brushless motor is connected with impeller, and impeller is arranged in the pump housing, and the pump housing is provided with water intake and water outlet.
Further, described dc brushless motor is arranged in the motor housing, and motor housing is provided with the mounting groove that no sensor frequency-variable controller group is installed.
Further, the described pump housing, motor housing and control mechanism all connect through screw.
Further, described no sensor frequency-variable controller group is the digital signal processor DSP electric machine control system.
Further, described dc brushless motor is a rare earth permanent-magnet synchronization motor.
Further, described dc brushless motor is a shield electric machine, and motor is provided with housing.
Further, described housing is formed by stainless steel stretched
The beneficial effect of the utility model is: through dc brushless motor and do not have the sensor frequency-variable controller and be used in combination the energy consumption that can reduce water pump greatly; Adopt constant pressure, constant current amount to reach, greatly improve the practicability of recycle pump automatically according to load size adjustment power.Need not carry out tap to motor and carry out the manual gear setting, that technology realizes is simple, can electrodeless variable-speed, easy to use.The system that adopts the structure of permagnetic synchronous motor, DSP electric machine controller and shield electric machine and form has characteristics such as no leakage, low noise, life-span length, little power consumption, maintenance be simple, and energy saving can reach more than 60%.
