Abstract
The invention relates to a modified diving through-flow pump. The cost of the modified diving through-flow pump is reduced while the pump lift is reduced and the modified diving through-flow pump increases the efficiency, has low cost and good economic returns. The modified diving through-flow pump comprises an internal cylindrical shell, an outer cylindrical shell, a dynamo, a water pump main shaft, a water straight tube, a top sleeve, an impeller part, and an impeller outer cylindrical shell and is characterized in that a motor rotor of the dynamo is connected with an input end of the water pump main shaft by a gear reducing mechanism.
Description
(1) technical field
The present invention relates to the plumbing equipment field, be specially a kind of improved submersible infusion pump.
(2) background technique
Existing submersed three-flow pump, see Fig. 1, its wheel member 1 directly is connected by middle water pump main shaft 4 with submersible motor 5, water pump main shaft 4 is installed in described inner barrel 8, the diffuser 3 formed cavitys, impeller housing 2 is equipped with in described wheel member 1 outside, and current pass through the rotation of impeller from impeller housing 2, by diffuser 3, from between inner barrel 8, outer cylinder body 7 formed cavitys, flow through, be directed to rising pipe through water outlet straight tube 6.Because the rotatingshaft of water pump and the rotatingshaft of submersible motor are the same axis, it is water pump main shaft 4, so the rotating speed of water pump is identical with the rotating speed of submersible motor 5, because the rotating speed of the lift of water pump and water pump square is directly proportional, need the area of low lift for design, thereby the rotating speed that reduces submersible motor 5 reduces pump rotary speed reaches the purpose that reduces pump head, just need to increase the number of poles of motor, the stator diameter of motor is big, the Heavy Weight of motor, increase cost, this submersed three-flow pump is applied in the low place of lift, and the operation of the inevitable operating mode partially of water pump causes the pumping plant unit efficiency low, low in economic efficiency, phenomenons such as vibration take place in water pump easily.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of improved submersible infusion pump, its cost when reducing pump head is reduced, and the efficient raising, and cost is low, and is good in economic efficiency.
A kind of improved submersible infusion pump, its technological scheme is such: it comprises inner barrel, outer cylinder body, generator, water pump main shaft, water straight tube, top cover, wheel member, impeller outer cylindrical shell, it is characterized in that: the rotor of described generator connects the input end of described water pump main shaft by reduction gears mechanism.
It is further characterized in that: described water straight tube is fastenedly connected described outer cylinder body one end, described outer cylinder body supports inner barrel by floor, in the described inner barrel generator is installed, described water pump main shaft is installed on diffuser inside, described diffuser is fastenedly connected described inner barrel, and described outer cylinder body supports diffuser by floor, and described water pump main shaft output terminal is fastenedly connected with the top cover, described top puts and is set with wheel member, and the impeller outer cylindrical shell is equipped with in described wheel member outside; Described reduction gears mechanism is specially gear reduction box, described gear reduction box tank ends is fastenedly connected respectively in described inner casing one end and described diffuser one end, described rotor output terminal connects the input end of described gear reduction box, and the output terminal of described gear reduction box connects the input end of described water pump main shaft.
In the said structure of the present invention, because described rotor connects the input end of described water pump main shaft by reduction gears mechanism, the high speed rotating of described motor is through the gearing down of reduction gears mechanism, export very low rotating speed, reduce the rotating speed of water pump, thereby reduce the rated lift of water pump, its efficient improves, cost is low, and is good in economic efficiency.
