Abstract
The invention discloses a kind of method of fluid pump and adjustment fluid pump best efficiency point, described fluid pump includes pump housing shell, this pump housing shell includes and can mutually cover and the main body of opening and upper cover, the delivery outlet for connecting output pipeline is provided with at the outer wall of main body, simultaneously in the upper inlet opening be covered with for connecting supplying tube, described fluid pump also includes multiple impeller that can be fixed on changing at any time by securing means in described fluid pump rotating shaft, and multiplely can coordinate described impeller and be sticked at the inner chamber packing ring of multiple different-thickness of described pump housing outer casing inner wall.
Description
Technical field
The present invention is about a kind of method of fluid pump and adjustment fluid pump best efficiency point.
Background technique
Traditional fluid pump is that the impeller that application rotates sucks fluid (such as water or other media), and is ejected in one or more diffusion admittance from the blade edge of impeller by fluid high-speed.Fluid pump, in order to be suitable for the usage requirement of various varying environment, is all by designing the different-diameter of the pump housing and thickness, being equipped with corresponding impeller, then the method such as different rotating speeds adjusting impeller is to obtain different pump parameters.Wherein outstanding is exactly some the BEP(best efficiency point of fluid pump) numerical value, when the BEP of fluid pump and the BEP of motor is inconsistent, or when not mating with system resistance, efficiency will sharply decline.Because fluid pump is mostly main equipment, be just difficult to change once installation.If be the external diameter using cutting impeller for the method adjusted when at present in use running operating point is gone far with the best efficiency point of fluid pump mutually, make its working curve close to high-efficiency point, but impeller just cannot recover after dicing, after using further, just cannot reach better using effect.
Summary of the invention
The object of the present invention is to provide a kind of method of fluid pump and adjustment fluid pump best efficiency point, the larger fluid pump after utilizing the method can make installation can obtain best efficiency point under various operating conditions.
Fluid pump in the present invention includes pump housing shell, described pump housing shell includes and can mutually cover and the main body of opening and upper cover, the delivery outlet for connecting output pipeline is provided with at the outer wall of described main body, simultaneously in the upper inlet opening be covered with for connecting supplying tube, described fluid pump also includes the impeller that can be fixed on changing at any time by securing means in described fluid pump rotating shaft, and described impeller can be coordinated and be sticked at the inner chamber packing ring of described pump housing outer casing inner wall, described inner chamber packing ring is the bar shaped part that a cross section is rectangle, described bar shaped part is fitted in the pump housing outer casing inner wall of described fluid pump, but do not affect the delivery outlet being located at described pump housing shell, one end of described bar shaped part is spherical in shape, the other end is one facilitate fluid pump inner fluid medium to export the scarf of delivery outlet to.
Described inner chamber packing ring is the bar shaped part that a cross section is rectangle.
The material of described inner chamber packing ring is metal or plastics.
Described securing means is screw rod.
The method adjusting fluid pump best efficiency point in the present invention is equipped with the inner chamber packing ring of multiple different-thickness and the impeller of multiple various outer diameter for fluid pump, uses the inner chamber packing ring and impeller that match under different operating mode.
The present invention is by being equipped with the impeller of multiple different size and the inner chamber packing ring of multiple different-thickness, and under different operating mode, different impellers is fixed in the rotating shaft of fluid pump by securing means, and be equipped with suitable inner chamber packing ring, there is advantage that is for convenience detach and that install.And when the parameter of alter pump makes it to mate with running environment, need not any machining, only need change detachable impeller and inner chamber packing ring, utilize the cavity volume of the pump housing shell of inner chamber packing ring alter pump, thus change operating mode.So, fluid pump structure becomes cordwood, can meet various different requirement when minimum quantity of stores.
