Description
Technical field
The drainage machinery technical field that the present invention relates to fetch water particularly, relates to a kind of deep-well pump.
Background technique
Deep-well pump is the machinery that sinks to water lift in the well bore.It is to immerse a kind of pump that aspirates in the underground water well with transporting water, is widely used in the deep extracting water of farmland discharging-irrigating, industrial and mining enterprise, rural potable water and level of ground water etc.Level of ground water is more and more darker in recent years, and general water pump is difficult to play a role, and the deep-well pump demand is more and more.The maximum characteristics of deep-well pump are that motor and pump are processed vertical one, require diameter little, conjuncted straight-bar type.
Because common deep-well pump generally adopts AC induction motor, the rotating speed of asynchronous motor receives the restriction of ac frequency, 2850 rev/mins of the rotating speeds of asynchronous motor when ac frequency is 50HZ, 3420 rev/mins of the rotating speeds during 60HZ.Make high necessary multi-stage impeller, 25 grades more than of the impeller up of the deep-well pump that has used of pump head.Improve the rotating speed of asynchronous motor, can significantly improve deep-well lift of pump, flow, reduce the impeller joint number of deep-well pump, dwindle the volume of deep-well pump.But the rotating speed that improves asynchronous motor generally is use frequency variator, and frequency variator is controlled AC induction motor again, and not high, the cost of efficient, control accuracy can significantly improve like this, therefore is difficult to promote, and needs do improvement further.
Summary of the invention
The problem that the present invention will solve is: the problem that is directed against above-mentioned existence provides a kind of and can significantly improve lift, flow, reduces the impeller joint number, dwindles the deep-well pump volume, alleviates well pump weight, the deep-well pump of raising the efficiency.
The technological scheme that the present invention adopted is: a kind of deep-well pump is provided; Comprise motor, coupling, electric machine controller, impeller, the pump housing; It is characterized in that said deep-well pump motor is a dc brushless motor; The output shaft of said dc brushless motor is connected through said coupling with the main shaft of deep-well pump, and said electric machine controller connects the said dc brushless motor of control, makes deep-well pump carry out work by the controlled speed of programming; Thereby the flow of deep-well pump and lift etc. are carried out intelligent control, and reduced volume reduces weight
Particularly, transfer controlled alternating impulse electric current to through said electric machine controller behind the deep-well pump input commercial power rectification and import said dc brushless motor, electric machine controller is taken a sample by power rectifier, mcu programming, the panel that power output etc. are formed and operated usefulness.
Compared with prior art, deep-well pumping provided by the invention is used dc brushless motor, can control rate; It is run up; Thereby make the flow of deep-well pump and lift controlled, can significantly improve lift and flow, can significantly reduce the impeller joint number of deep-well pump like this than asynchronous motor deep-well pump; Dwindle the height and the weight of deep-well pump, optimize the function of deep-well pump; And adopt dc brushless motor can also pass through the electric machine controller programing operation, and intellectualized operation is carried out in deep-well pump work, also dc brushless motor is provided various protections such as overvoltage, overcurrent, overheated, electric leakage, realize semi-automatic automatically the operation; The efficient of dc brushless motor at a high speed is all more than 83%, and energy-conservation ten minutes is remarkable, and is more energy-conservation up to 20% than general small-bore small-sized single-phase Pump for well.
