How to end sewage pump blockage

How to say goodbye to sewage pump jam!Why is the anti - clogging performance of sewage pump more and more important?That mainly comes from two aspects: one is the cost of sewage disposal increased industrial enterprises are trying to reduce the water consumption per unit product production, which made of solid material and fiber content in the wastewater is more and more high two sewage pumps are increasingly adopted the means of energy saving, is the speed adjusting drive mode, and the speed adjusting is not guarantee sewage pump will jam aiming at the problem of frequent clogging impurities machine pump impeller, equipment operation early every wall shall be clear, air is not for the nightThough this avoids the shutdown, but often remove the pump body, cause the machine parts such as pump inlet ring wear at the same time each time the air cost a lot of human in order to change this situation, the adding of carbon steel in the pump inlet line resistance box, box and 45 Angle using the filter to filter impurities again, avoid congestion team fouling resistance for 1 ~ 3 times a month after the clean-up of the plan implementation received certain effect, human consumption ease resistance corrupt department have a vent valve at the bottom, but there is still a corner part of the sewage and impurities in the corner after the accumulation, in cleaning up minor gas poisoning easy cause personnel injury, is not conducive to safe operationSewage pump rotor blade shape can be divided into two kinds, swirling blades and cutting blade, respectively, in the form of the two most widely vortex flow impeller blade is not in the medium to be delivered, according to the principle of fluid dynamics to boot into the pump chamber, pumping medium is pumped from the impeller flow through the medium of this way, by pumping liquid medium long fiber or solid material also be pumped out and cutting blade, can cut up a larger block solid material, which is no longer blockedTo ensure the safe operation of the key equipment, and the catalyst of metering pump is mainly used for catalyst note, prompting oligomer in polycondensation reactor final polycondensation reactor polyester polycondensation reaction process requirement within the catalyst must be according to certain proportion, injection and stop injection time can't more than 15 rain otherwise will reduce the melt viscosity, such as product quality drop catalyst in order to ensure the smooth running of the pump, some guarantee measures must be taken at regular intervals to replace the wearing parts, lubricating oil and the catalyst of metering pump inside the main moving parts are worm worm gear sliding block set new piston and so onThese parts to reduce wear and tear will directly lead to pump or not, the current solution is the regular replacement of wearing parts, and regular cleaning of lubricating oil hydraulic chamber catalyst metering pump operating rules strictly, catalyst metering pump start and stop should be used in strict accordance with the requirements of operating at startup, zero output open pump, to pump discharge not for voltage plate filling nitrogen has a certain pressure to avoid diaphragm deformation is caused by the nitrogen filling, to prevent diaphragm rupture.Increase pump output, to be slow;When the pump is stopped, also should be slow to reduce the output of the pump to strengthen the maintenance of the pump, pump running during regular visit, focusing on sound machine oil pump outlet pressure nitrogen gas buffer tank pressure on a regular basis to replace diaphragm nitrogen gas buffer tank diaphragm pump body, in order to effectively prevent damage of the pump at the same time cause catalyst stop the happening of the accident
如何告別污水泵堵塞！
  污水泵的抗堵塞性能為什么會(huì )被越來(lái)越看重？這主要源于兩方面原因：一是污水處置費用的zg。工業(yè)企業(yè)都在努力降低單位產(chǎn)品生產(chǎn)的耗水量，這使污水中固體物質(zhì)和纖維的含量越來(lái)越高。二是污水泵越來(lái)越多地采用了節能的手段，就是轉速調節的驅動(dòng)方式，而轉速調節卻不能保證污水泵會(huì )不會(huì )堵塞?！?br /> 　　針對雜質(zhì)頻繁堵塞機泵葉輪的問(wèn)題,設備運行初期采用每堵必清，清堵不過(guò)夜的方法。雖然這樣避免了停工，但經(jīng)常拆卸泵體，造成機泵口環(huán)等部件的磨損加劇同時(shí)每次清堵耗費大量人力。為改變這種狀況，在機泵進(jìn)水管處加裝碳鋼阻污箱，并呈45。傾角。箱內使用過(guò)濾網(wǎng)以再次過(guò)濾雜質(zhì)，避免堵塞發(fā)生。班組每月對阻污進(jìn)行1～3次的清污。此方案實(shí)施后收到了一定的效果，人力消耗得到hj。阻污箱底部有放空閥，但仍存在死角。部分污水及雜質(zhì)在死角積聚后，在清理中易造人員的輕微氣體中毒傷害，不利于作業(yè)?！　?br /> 　　污水泵轉子葉片的形態(tài)分為兩種，分別為旋流式葉片和切削式葉片，這兩種形態(tài)的葉片使用的。旋流式葉輪并不在被輸送的介質(zhì)中運動(dòng)，根據流體動(dòng)力學(xué)原理把需要泵送的介質(zhì)引導到泵腔中，被泵送的介質(zhì)從葉輪旁流過(guò)。這樣，被泵送的液體介質(zhì)中的長(cháng)纖維或者固體物質(zhì)也一起被泵送出去。而切削式葉片，能將較大的塊狀固體物質(zhì)切碎，從而不再堵塞?！?br /> 　　確保關(guān)鍵設備運行,催化劑計量泵主要用于催化劑的注人，促使齊聚物在預縮聚釜、終縮聚釜內發(fā)生縮聚反應。聚酯工藝要求催化劑按一定比例注人，而且停注時(shí)間不能超過(guò)15rain。否則將使熔體粘度降低，產(chǎn)品質(zhì)量降等。為保證催化劑泵的平穩運行，采取一些保證措施?！　?br /> 　　定期更換潤滑油及磨損件,催化劑計量泵的內部主要運動(dòng)件有蝸桿、蝸輪、滑塊、定新活塞等。這些部件的磨損將直接導致泵流量降低或根本不上量，目前解決的辦法就是定期更換潤滑油、磨損件及定期清洗液壓腔?！?br /> 　　嚴格催化劑計量泵操作規程,催化劑計量泵的啟動(dòng)和停車(chē)都應嚴格按照使用要求進(jìn)行操作。在啟動(dòng)時(shí)，零輸出開(kāi)泵,待泵出口有一定壓力時(shí)方可對穩壓盤(pán)充氮氣。避免因充氮氣造成隔膜變形較大，防止隔膜破裂；提高泵輸出時(shí)，要緩慢進(jìn)行；停泵時(shí)，也應緩慢降低泵的輸出?！?br /> 　　加強泵的維護,泵在運行期間定期巡檢，檢查潤滑油油位、機泵聲音、出口壓力、氮氣緩沖罐壓力等。定期對泵體隔膜、氮氣緩沖罐隔膜進(jìn)行更換，以地防止兩臺泵同時(shí)損壞造成催化劑停注事故的發(fā)生。
