單級混流泵A張北單級混流泵150HW-12

The materials for the Water Guide pipe, the pump body and the pump cover are cast iron. There are infiltrating grooves on the inner surface of the rubber guide bearing near the wheel, and the guide bearing is mounted directly in the housing of the pump body, which can be replaced on site after wear. The rolling bearings contained in the pump cover are two single-row phase ball bearings. The main factory producing guanting is Fujian Youxi guanting factory. (Ix) Manual pumping of labor-driven piston pumps, diaphragm pumps and screw pumps and other water extraction tools, collectively referred to as manual pumps. Manual pumps are divided into shallow well dynamic pumps and deep wells manual pumps. The flow rate of shallow well piston pump is 0.34~4.214 cubic meter/time, adapt to the suction process 2~7 meters. The flow rate of the deep well piston pump is 0.056~0.601 cubic meters/When the head is 15~40 m. The flow rate of the diaphragm pump is 0.8~6.01 cubic meters/when the flow rate of the screw pump is 0.056~0.671 cubic meter/time. (10) The pump shell of the pump is generally cast iron, it is easy to crack under the action of mechanical force or thermal stress.

一.概述

1.用途：HW混流泵為臥式，單級，單吸，渦殼式混流泵。適用于輸送清水或物理，化學性質類似于水的其它液體。被輸送液體溫度不宜高于50度。廣泛用于農田灌溉，工業和城市排水等多種場合。HW泵的性能范圍：流量90-9000m3/h    揚程3.5-22m。

2. 特點：結構簡單，使用可靠，裝修方便，而且效率高，體型小，重量輕。jdhuiquan4.20

3. 傳動方式：用直接傳動和變速傳動。常用動力機是電動機和柴油機。訂貨   時應明確動力機的型號，以便確定聯軸器和皮帶輪的型號

共有84種產品，分3個派生系列，413個規格型號。（1）性能范圍泵口徑50～200毫米，流量12.5～400立方米/時，揚程8～125米，配力有柴油機直聯、皮帶傳動，電動機直聯，功率1.1～110千瓦，轉速1450～2900轉/分。（2）結構型式輕小型離心泵為軸向單級單吸懸架式離心泵，泵體后開門，出口位于中心向上，后蓋為壓嵌式，軸承體與泵體直接聯結，泵腳位于泵體下方，軸承用黃油潤滑，軸封分為軟填料、機械密封、橡膠油封三種。葉輪均為閉式，傳動分為聯軸器傳動和皮帶傳動兩種。泵葉輪轉向：從泵進口方向看。葉輪轉向為順時針，當泵與柴油機直聯傳動時，為逆時針。泵出口可裝置手動泵，可去掉底閥，減少水力損失，并能使泵自吸。

二.結構和作用

不能隨意選擇要根據實際需求來進行選擇。首選要對電動機接地裝置進行檢查。對于臥式混流泵與電動機共軸的電泵。電動機需要在適合的位置上設有一定數量的接地螺釘，而且需要在接地螺釘附近設有接地標志;同時臥式混流泵還需要有可靠的接地裝置和接地線，線上需要有較為明顯的接地標志，這種接地標志需要在電機使用期內不會被磨掉。這點是臥式混流泵的重要安全指標之一在選購的時候可要多加注意。混流泵的性能與和離心泵比較，揚程低一些，而流量大一些；與軸流泵比較，揚程高一些，流量小一些。混流泵的性能曲線形狀也是介于離心泵和軸流泵之間，對于高揚程混流泵，其流量與揚程、流量與功率的相互關系變化規律接近于離心泵，在使用上，可采用關閉閥門啟動。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 performance of the impeller.
