Further, the even water ware is divided into symmetrical shape two halves, the i.e. even water ware of influent side（The half of influent side）With go out
The even water ware in water side（The half of water outlet side）, the even water ware of influent side is connected with water inlet pipe.
Further, the even water ware inwall bottom flushes with water inlet inside pipe wall bottom, its top and water inlet inside pipe wall top
Portion flushes.
Further, the even water ware bottom thickness of slab and side thickness are all 0.2D, and free height is equal with water inlet pipe diameter, even
Water ware external diameter size is 4.33-4.5D, and pit shaft internal diameter 5D, D are water pump vane diameter.
Further, the area of the annular intake chamber and water inlet pipe mouth area equation.
Further, the even water ware of the influent side, the bottom of the even water ware of water outlet side pass through cross beam support, crossbeam both ends respectively
It is fixed on shaft in wall.
Further, the crossbeam uses I-shaped or bathtub construction, meets rigidity requirement.
Further, the even water ware uses aluminium alloy or glass-reinforced plastic material.
Further, the even water ware of the influent side, the even water ware of water outlet side are lifted into pit shaft respectively, are bolted to horizontal stroke
Liang Shang.
Further, the overall diameter of the even water ware and water inlet well width are according to intake chamber size and mineshaft diameterD W
Calculate and determine.
The present invention is used for the pump installation of well shaft type water inlet, and even water ware is located above impeller, in its inwall bottom and water inlet pipe
Wall bottom flushes.The setting of even water ware makes current in well more smooth out, and avoids the generation of whirlpool as far as possible, improves the uniform of current
Property, so as to improve the flow velocity uniformity of impeller eye.Therefore, the hydraulic loss in pit shaft will reduce, and pump assembly efficiency is corresponding
Improve.
The present invention is applied to the various pump installations intake using well shaft type, can reduce the formation of whirlpool, make water-flow equation
More have, pump installation overall performance significantly improves, energy-saving.
Well shaft type pumping plant has greater advantage in terms of urban water supply and draining, mainly obtained in municipal works field compared with
It is widely applied.The present invention, which is advantageous to various well shaft type pumping plants, improves Inlet flow pattern, reduces hydraulic loss, improves pump installation effect
Rate, energy consumption is reduced, technically reliable is easy to implement, has a extensive future, and economic benefit is big.
