單級混流泵A博野單級混流泵250HW-8
When the pump in the work due to cavitation impact or in the winter did not release the pump shell in the water and frozen is also prone to rupture, such as damage is heavier can not be repaired when the new pump shell should be replaced. Pump shafts are generally carbon steel parts, but due to manufacturing quality, use or installation and other reasons are also vulnerable to damage. Pump shaft may appear cracks, bending, shaft neck wear, thread damage, etc., may also appear fracture. If the damage is serious and cannot be repaired, the new shaft should be replaced. The impeller is an important working part of the pump and is made of cast iron. Due to manufacturing quality and use and other reasons are also vulnerable to damage. The impeller may appear cracks, due to cavitation effect on the surface of the bation of a nest eye or perforation, long-term flushing to make the leaves thin or partial grinding, and even crushed by debris. Some defects can be repaired; some defects cannot be repaired, that is, new impellers should be replaced. The bearing of the sliding bearing is cast of copper tin alloy, the wear resistance is very poor, is one of the most easy to wear and burn the wearing parts, the bearing can generally be repaired, can also be replaced with new parts. Rolling bearings generally have an average service life of 5,000 hours.
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(yè)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

通常泵的流量用體積計算，以Q表示，單位為米3/時（m3/h）、米3/秒（m3/s）、升/秒（1/s）。也可用重量計，以G表示，單位為噸/時（t/h）、噸/秒（t/s）、千克/秒（kg/s）。G與Q的關系：G=r×Qr-液體重度（千克/米3）因水的重量近似1000千克/米3，故1升/秒=3.6米3/時=3.6噸/時揚程（H）泵的揚程是指單位重量的液體通過泵所增加的能量。以H表示，實質上就是水泵能夠揚水的高度，又叫總揚程或全揚程。單位為米液柱高度，習慣上省去“液柱”，以米（m）表示。泵的總揚程由吸水揚程與出水揚程兩部分組成，因此總揚程=吸水揚程=出水揚程但由于水流經過管路時受到各種阻力而減少了泵的吸水揚程和出水揚程。

（1）ZB型性能范圍流量2～200米3/時，揚程8～100米，配套功率0.25～45千瓦。（2）結構型式特點按泵的配力機類型分為電動機配套自吸泵和柴油機配套自吸泵。按實現自能的結構與工作特點可分為內滑式、外滑式、水環(huán)輪式和其他型式。傳動方式有直聯傳動（包括內軸）和皮帶傳動。進口直徑25～200毫米，共10個口徑，54個規(guī)格。管道輸水灌溉機組由動力機、農用泵、管路等組成的可移動輸水灌溉機組稱為輕小型管道輸水灌溉機組（簡成為灌溉機）。它是近年來灌溉方法上新興的一種灌溉機械，有G型輕小型管道輸水機組和CB型輕小型柴油機-泵直聯機組。（1）G型管道輸水灌溉機組動力：柴油機、電動機（2.2～11.03千瓦）；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.
