Description
[technical field]
This practicality relates to a kind of novel water pump, particularly a kind of water pump be arranged in Shui nationality industry.
[background technique]
Water pump is conveying liquid or the machinery making fluid pressurization.It sends the mechanical energy of prime mover or other external energies to liquid, liquid energy is increased, be mainly used to conveying liquid and comprise water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc., also can carry liquid, gaseous mixture and the liquid containing suspended solids.The technical parameter of pump performance has flow, inhales journey, lift, air horsepower, water-horse power, efficiency etc.; The types such as volume water pump, vane pump can be divided into according to different working principles.Displacement pump utilizes the change of its swept volume of a single chamber to carry out transferring energy; Vane pump utilizes the interaction of rotary vane and water to carry out transferring energy, has the types such as centrifugal pump, axial-flow pump and mixed flow pump.
The working principle of centrifugal pump: before water pump starts, first pump and intake pipe are filled water, after pump operation, transfer the effect of the centrifugal force produced at impeller high-speed rotary under, water in impeller channel is thrown toward surrounding, press-in spiral case, impeller eye forms vacuum, and the water in pond is inhaled into along suction sleeve and supplements this space under external atmospheric pressure.Then the water sucked is thrown away by impeller again and enters outlet pipe through spiral case.As can be seen here, if centrifugal pump impeller constantly rotates, then can to absorb water continuously, setting-out, water just can raise eminence or a distant place from lower continuously.In sum, centrifugal pump is under the effect of centrifugal force owing to producing at the High Rotation Speed of impeller, water extraction is hoisted, therefore claims centrifugal pump.
The general characteristic of centrifugal pump:
(1) water is suck along the axis of impeller along the direction that flows through of centrifugal pump, and outflow perpendicular to axial direction, namely water inlet and outlet flow path direction is in 90 ° mutually.
(2) because centrifugal pump forms vacuum dehydration by impeller inlet, therefore diversion must be poured in pump He in suction sleeve at prestart, or bleed with vacuum pump, vacuum is formed to discharge air, and pump case and suction line must strict sealings, must not leak gas, otherwise can not form vacuum, also just not inhale water.
(3) because impeller inlet can not form absolute vacuum, therefore centrifugal pump suction lift can not more than 10 meters, add the linear loss that current bring through suction line, actual allowabler mounting height (water pump spindle line-spacing sucks the height of the water surface) is much smaller than 10 meters.As too high in installed, then do not absorb water; In addition, because mountain area is lower than Plain atmospheric pressure, therefore same water pump is in mountain area, and when particularly installing in alpine region, its setting height(from bottom) should reduce, otherwise can not suct water.
Water pump in tradition Shui nationality industry, it controls drive motor running circuit plate and motor is installed together, be potted in electric machine casing by sealer afterwards, when control the circuit board of drive motor break down break down time, circuit board can not be removed and change, thus cause whole water pump to be scrapped, cause great waste.
Owing to there are the problems referred to above, be necessary to propose solution to it, of the present utility modelly make in this context just.
