1、減小軸承損失2、減小填料函損失①根據(jù)混流泵的用途和工作場所選擇適合的填料。②保持填料壓蓋合適的松緊程度。3、減小混流泵內(nèi)部的摩擦損失混流泵內(nèi)部的摩擦損失包括:①水流與泵體泵蓋表面產(chǎn)生的摩擦損失;②水流與葉輪高低壓兩側(cè)流道的表面產(chǎn)生的摩擦損失;③混流泵內(nèi)部各轉(zhuǎn)動部件配合面之間的摩擦損失。
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(xué)性質(zhì)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(nóng)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(yáng)程3.5-22m。
2. 特點(diǎn):結(jié)構(gòu)簡單,使用可靠,裝修方便,而且效率高,體型小,重量輕。jdhuiquan5.15
3. 傳動方式:用直接傳動和變速傳動。常用動力機(jī)是電動機(jī)和柴油機(jī)。訂貨 時應(yīng)明確動力機(jī)的型號,以便確定聯(lián)軸器和皮帶輪的型號

注意事項: (1),用皮帶傳動時,水泵和動力機(jī)的皮帶輪應(yīng)對正。皮帶輪和皮帶外要設(shè)安全罩。 (2),泵蓋一般不宜直接連彎管,應(yīng)先接直管后再接彎管,以保證進(jìn)口處流速分布均勻。 (3),管路各連接法蘭間,應(yīng)加橡膠墊或石棉線,以防漏氣漏水。 (4),進(jìn)水管伸入進(jìn)水池的位置應(yīng)合適,進(jìn)水管口距河底一般為1D—3D,進(jìn)水管口距最低枯水面一般為1D—3D,進(jìn)水管距進(jìn)水池壁一般為(1—1.5)D(D為進(jìn)水管口徑。2小泵取大值,大泵取小值)。
二.結(jié)構(gòu)和作用
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.
Water pump, valve and accessories technology R & amp; d and Sales: motor, bearings, mechanical seals, bl Products Sales: Pump assembly and maintenance: self-and with all kinds of goods and technology import and export business (except for goods and technologies that the state limits the company to operate or prohibit imports and exports).
