    Suction tank should be easy to clean before. (4) Considering the landing of the water surface, the b of the suction pipe end should have enough submerged depth to prevent the intake from the whirlpool. (5) Before installation, to carefully check whether the bottom valve is flexible, at the same time in order to facilitate inspection and maintenance, to consider a good installation b. (6) The gate valve installed on the inlet side shall be installed in a horizontal direction or tilted downwards to avoid the accumulation of air. Import Side Gate valve In addition to inspection, switching outside, must be fully open. At the same time should try not to let the air from the sealing sleeve area. (7) The bending part is as smooth as possible, reducing the number of elbows, and should try to avoid being set close to the inlet of the pump. (8) When there is a different diameter tube, in order not to allow air to accumulate, should use eccentric type of pipe. (9) For parallel operation of the pump inlet pipe, it is advisable to use a separate water inlet pipe. If the use of direct to the common mother tube, easy to occur the imbalance of import pressure. The drive (motor) drives the impeller to rotate through the pump shaft, and the blade of the impeller drives the liquid to rotate together.

    S、SH單級雙吸中開式離心泵產(chǎn)品特點(diǎn)1、密封系統(tǒng):可供選用的機(jī)械密封、填料密封其冷卻潤滑均采用內(nèi)循環(huán);2、流量大、效率高:雙吸葉輪,具有流量大、效率高等特點(diǎn);3、可更換的軸套:軸套作為易損件,起到保護(hù)軸,提高泵的使用壽命;4、密封環(huán):密封環(huán)作為易損件,起到提高泵的效率、延長泵的使用壽命的特點(diǎn)。S、SH單級雙吸中開式離心泵產(chǎn)品用途

    Installation b is different, vertical pump for the overall connection, installation is easier, and horizontal pump after installation needs to be adjusted for precision. Maintenance difficulty is different, vertical pump maintenance is difficult, such as maintenance impeller need to remove all the upper part can be carried out, and horizontal pump is relatively easy. In the process of opening the pump in use, sometimes it will appear blockage phenomenon, then how should we solve it? Here's a specific introduction for you. To ensure the safe operation of critical equipment in the pump is mainly used for catalyst injection, to promote the polymerization in the pre-condensation kettle, the final condensation tank in the condensation reb. Polyester process requires that the catalyst must be in a certain proportion of people, and the stop time can not exceed 15rain, otherwise the melt viscosity will be reduced, product quality and so on. In order to ensure the smooth operation of the catalyst pump, some guarantee measures must be taken. Regular replacement of lubricating oil and wear parts pump internal main moving parts have worm, worm wheel, slider, fixed new piston and so on. Wear of these components will directly result in reduced pump flow or no amount at all.

    主要適用于工廠、礦山、城市給水、電站、農(nóng)田排灌和各種水利工程。jdhuiquan4.13

    S、SH單級雙吸中開式離心泵概述

     S型單級雙吸水平中開式離心泵。該型泵吸入口和排出口均在泵軸心線下方,檢修時(shí),只要將泵蓋揭開,即可將全部零件拆下進(jìn)行維修。S型泵主要由泵體、泵蓋、軸、葉輪、密封環(huán)、軸套、軸承部件等組成。其性能符合JB/1050-93《單吸雙吸清水離心泵型式與基本參數(shù)》標(biāo)準(zhǔn)。
    主要用于輸送不含固體顆粒的清水或物理化學(xué)性質(zhì)類似水的其它液體。適用于工業(yè)和城市給排水、農(nóng)田排灌。

    故效率總是小于1的。目前國內(nèi)中開泵中多數(shù)型號的效率一般在70-80%左右,少數(shù)大流量型號的效率在90%左右。影響中開泵效率的主要原因在于泵內(nèi)存在的能量損失,這些損失主要是機(jī)械損失,水力損失和容積損失。機(jī)械損失主要是葉輪外表面與液體的磨擦損失(即圓盤摩擦損失)以及離心泵軸承,軸封上的摩擦損失,水力損失主要是液體在泵內(nèi)運(yùn)動速度和方向的變化引起的沖擊損失。中開泵效率是指泵的有效功率和軸功率的比值旋渦損失等,液體與泵內(nèi)各流道壁面的磨擦損失以及液體運(yùn)動的內(nèi)部磨擦損失,容積損失主要是泵內(nèi)高壓液體向低壓區(qū)泄露回流造成的損失,包括密封環(huán)泄漏損失,平衡機(jī)構(gòu)泄漏損失和級間泄漏損失。通過不同可以使中開泵的效率和汽蝕性能得到很好的提升當(dāng)然在進(jìn)行效率和汽蝕性能改造的同時(shí)。
