Imported horizontal single-stage single-suction centrifugal pump water, is the joint design of energy-saving pump, which is the other single-stage centrifugal pump water newer. Advantages are: a full range of hydraulic performance and reasonable layout, the user selects the range, easy maintenance; efficiency and suction lift up to international advanced level average. This pump is suitable for industrial and urban water supply, drainage, irrigation and agriculture can also be used for conveying water or physical and chemical properties similar to water or other liquids, the temperature is not high 80 ℃.
產(chǎn)品特點(diǎn)Features
1、進(jìn)口臥式單級單吸清水離心泵根據(jù)國際標(biāo)準(zhǔn)ISO2858所規(guī)定的性能和尺寸設(shè)計的，主要由泵體、泵蓋、葉輪、軸、密封環(huán)、軸套及懸架軸承不見等組成。
2、進(jìn)口臥式單級單吸清水離心泵的泵體和泵蓋部分，是從葉輪背面處剖分的，即通常所說的后開門結(jié)構(gòu)形式。其優(yōu)點(diǎn)是檢修方便，檢修時不動泵體，吸入管路，排出管路和電動機(jī)，只需拆下加長聯(lián)軸器的中間聯(lián)接件，即可退出轉(zhuǎn)子部分進(jìn)行檢修。
3、泵的殼體(即泵體和泵蓋)構(gòu)成泵的工作室。葉輪、軸和滾動軸承等為泵的轉(zhuǎn)子。懸架軸承部件支撐著泵的轉(zhuǎn)子部分，滾動軸承受泵的徑向力和軸向力。
4、為了平衡泵的軸向力，大多數(shù)泵的葉輪前、后均設(shè)有密封環(huán)，并在葉輪后蓋板上設(shè)有平衡孔，由于有些泵軸向力不大，葉輪背面未設(shè)密封環(huán)和平衡孔。
5、泵的軸向密封環(huán)是由填料壓蓋，填料環(huán)和填料等組成，以防止進(jìn)氣或大量漏水。泵的葉輪如有平衡，則裝有軟填料的空腔與葉輪吸入口相通，如葉輪入口處液體處于真空狀態(tài)，則很容易沿著軸套表面進(jìn)氣，故在填料腔內(nèi)裝有填料環(huán)通過泵蓋上的小孔，將泵室內(nèi)壓力水引至填料環(huán)進(jìn)行密封。泵的葉輪如沒有平衡孔，由于葉輪背面液體壓力大于大氣壓，因而不存在漏氣問題，故可不裝填料環(huán)。
6、為避免軸磨損，在軸通過填料腔的部位裝有軸套保護(hù)。軸套與軸之間準(zhǔn)有O型密封圈，以防止沿著配合表面進(jìn)氣或漏水。
7、泵的傳動方式是通過加長彈性聯(lián)軸器與電動機(jī)聯(lián)接的，泵的旋轉(zhuǎn)方向，從驅(qū)動端看，為順時針方向旋轉(zhuǎn)。
1, imports of horizontal single-stage single-suction centrifugal pump water based on performance and size ISO2858 international standard provisions designed mainly covered by the pump, pump, impeller, shaft seal rings, bushings, bearings and suspension but not other components.
2, imports of horizontal single-stage single-suction centrifugal pump water pump body and pump cover part of the back office split from the impeller, that is commonly referred to as post-formal-door structure. The advantage is easy maintenance, repair does not move when the pump, suction line, discharge line and the motor, just remove the spacer coupling intermediate coupling member, you can exit the rotor parts for maintenance.
3, the pump housing (ie, pump and pump cover) constitute the pump studio. Impeller, shaft and rolling bearings as the pump rotor. Suspension bearing member supporting the rotor portion of the pump, the rolling bearing by radial and axial forces of the pump.
4, in order to balance the axial force of the pump, the impeller of the pump before the most, after the sealing ring has, in the rear cover plate is provided with an impeller balance holes, due to force some small shaft, the impeller is not provided on the back of the seal rings and balance holes.
5, pump axial seal ring is composed of packing gland, packing ring and filler and other components to prevent water leakage into the air or a lot. If the pump impeller balance is equipped with wadding impeller inlet in communication with the cavity, impeller inlet of liquid in a vacuum, it is very easy along the surface of the intake sleeve, so the packing chamber equipped with packing rings by hole pump cover, the pump chamber pressure of water lead to the packing ring seal. If no pump impeller balance holes, due to the back of the impeller fluid pressure greater than atmospheric pressure, so there is no leakage problems, it is time to install packing rings.
6, to avoid shaft wear in the shaft through the packing chamber parts fitted sleeve protection. Associate O-ring between the sleeve and the shaft to prevent along the mating surface of the intake or leaking.
7, the pump drive is through lengthened flexible coupling and motor coupling, rotation direction of the pump from the drive end, clockwise rotation.
