The pond filter pump of high-efficiency and low-cost
Technical field
The present invention relates to a kind of pond filter pump, specifically relate to a kind of pond filter pump of high-efficiency and low-cost.
Background technique
Basin, bathing pool and swimming pool, below be referred to as pond, because of it, has the several functions such as bathing and amusement and recreation, obtained the general recognition and acceptance of society.Each pond is supporting a pond filter pump, and to realize the function of drawing water and filtering, pond filter pump mainly comprises shell and establishes filter chamber, filter core, motor, impeller in the enclosure.Motor and impeller are arranged in motor shell usually, motor shell comprises the impeller cavity of accommodating impeller and the pump housing of accommodating motor, and the impeller cavity is communicated with outlet pipe and intake pipe, still, the impeller cavity body structure that usually adopts on market now is: circular impeller cavity is communicated with outlet pipe, as shown in Figure 1.During work, after current entered the impeller cavity from intake pipe, under the leading role of rotary blade, the direction of current and outlet pipe at an angle of 90, were unfavorable for the smooth discharge of water, had that flow is little, pressure is low, inefficient problem.
The pond filter pump flow is little, pressure is low in order to solve, inefficient problem, notice of authorization number is the patent documentation of CN2541640Y, a kind of Water pool filter pump is disclosed, as shown in Figure 2, by at outlet pipe port and impeller cavity joint design one outer arch convex structure with Impeller Design is become to centrifugal, solved to a certain extent that flow is little, pressure is low, inefficient problem.But, the motor type of pond filter pump is generally the single-phase AC permanent-magnet synchronous machine, the working principle of this motor is: when switching on power, stator coil produces pulsating field, can resolve into two forward and reverse rotating magnetic fields, thereby motor may turn clockwise and also may be rotated counterclockwise during stable state, so start rear steering at every turn, is uncertain.Therefore, outlet pipe and impeller cavity adopt centrifugal layout to there will be following situation: while being clockwise, flow is normal when the impeller starting direction; While being counterclockwise, water is difficult to press out from outlet pipe when the impeller starting direction, so flow is very little, still has that flow is little, pressure is low, inefficient problem.
In addition, pond filter pump structure in the market, the ubiquity protection Design is considered incomplete phenomenon, easily to the Consumer, brings injury; Simultaneously, during design, structural member is too much, connects too much, causes manufacture cost too high, and quality is unstable.
