才能插秧，此后作物生長期用水量較少。因此對水稻田灌水量最多的是泡田期，所以一般用泡田灌水量作為計算所需流量的依據。泡田灌水量與土壤性質、地下水深度有關。水稻生育期灌水量與田間蒸發(fā)、滲漏有關，一般每晝夜耗水6～10毫米，出穗開花期每晝夜耗水10～15毫米，旱田作物一般播前和生育期灌水量分別為50～60米3/畝和25～50米3/畝。所需水泵揚程的確定如前所述，水泵的揚程系指總揚程，即實際揚程加上損失揚程。所需實際揚程，可通過各種方法實地測量出來。所需損失揚程，可通過以下步驟確定：（1）根據前述計算出的所需流量，查水泵性能表，選定所需水泵的口徑，并根據水泵的口徑選定水泵進、出管直徑。（2）水泵型號的確定當所需的流量和揚程確定之后。

目前用內燃機拖動水泵的機組大都采用皮帶間接傳動。皮帶傳動按所用皮帶的種類不同可分為平皮帶和三角膠帶兩種。此外近年來還出現(xiàn)齒帶。平皮帶在內燃機拖動水泵機組上應用較多，它的適用范圍較廣，傳動方向可以多變，但傳動比較小，皮帶易打滑，傳動損失大，效率較低。平皮帶的傳動方式有開口式傳動、交叉?zhèn)鲃雍桶虢徊鎮(zhèn)鲃尤N，開口式傳動適用于水泵與電機兩軸平行，轉向相同、轉速不同也可相同的傳動；交叉?zhèn)鲃舆m用與兩軸平行、轉向相反、轉速不同也可相同的傳動上；半交叉?zhèn)鲃舆m用于兩軸相互垂直、轉速不同也可相同的傳動上。三角膠帶具有梯形斷面，裝在皮帶輪的梯形槽中。由于三角膠帶是膠帶的兩個側面與輪槽兩側緊密接觸，摩擦力比平皮帶大，所以傳動比較大。

Guanting simple structure, convenient management, is a use of natural water resources as the driving force of low-cost water extrb machinery. The type of guanting can be divided into coaxial and non-coaxial according to the spindle connection of hydraulic turbine and pump, and there are two kinds of axial flow type and mixed flow type according to the type of wheel, and the water required by work is divided into low head, middle head and high head, which is divided into water extrb type and power output type according to the application requirement. The selection of guanting should be based on the hydrological and geological data of the station area to determine the b of the station, the possible use of water head and overflow flow, from the geographical distribution of the mechanical irrigation area to obtain a reasonable economic geometric lift, according to the crop type and soil and other water conditions to determine the water demand in the irrigation area, and then identify the appropriate model The main parts of guanting are rotary wheel, spindle, water guide seat, impeller, pump body, pump cover, guide bearing, rolling bearing and so on. The rotary wheel is a four blade paddle type, made of cast iron. The spindle material is high quality carbon steel, one end fixed wheel, the other end fixed impeller, impeller made of cast iron.1.HW pump mainly has pump cover, impeller, pump body, pump shaft, bushing, and bearing body and other major components. The pump cover is connected with the pump body and the inlet pipe respectively. 2. There should be an appropriate gap between the pump cover plane and the impeller plane. The gap is too small will produce friction, the gap is too large, will lead to the pump body pressure water a large number of reflux, is the pump efficiency reduction. The suitable gap used in practice is 0.3-0.7mm, and the gap can be adjusted by adding and subtracting the thickness of the paper pad.
3. The shaft is applied to protect the pump shaft and should be replaced in time after wear.
1. Screw holes at the upper end of the pump body, used for filling water diversion or connecting vacuum pump pumping gas to divert water.
2. In order to expand the scope of application of the pump to meet the different needs of users, can cut the outer diameter of the impeller or exchange different perbance of the impeller.
