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
如何告别污水泵堵塞！
  污水泵的抗堵塞性能为什么会被越来越看重？这主要源于两方面原因：一是污水处置费用的zg。工业企业都在努力降低单位产品生产的耗水量，这使污水中固体物质和纤维的含量越来越高。二是污水泵越来越多地采用了节能的手段，就是转速调节的驱动方式，而转速调节却不能保证污水泵会不会堵塞。　
　　针对杂质频繁堵塞机泵叶轮的问题,设备运行初期采用每堵必清，清堵不过夜的方法。虽然这样避免了停工，但经常拆卸泵体，造成机泵口环等部件的磨损加剧同时每次清堵耗费大量人力。为改变这种状况，在机泵进水管处加装碳钢阻污箱，并呈45。倾角。箱内使用过滤网以再次过滤杂质，避免堵塞发生。班组每月对阻污进行1～3次的清污。此方案实施后收到了一定的效果，人力消耗得到hj。阻污箱底部有放空阀，但仍存在死角。部分污水及杂质在死角积聚后，在清理中易造人员的轻微气体中毒伤害，不利于作业。　　
　　污水泵转子叶片的形态分为两种，分别为旋流式叶片和切削式叶片，这两种形态的叶片使用的。旋流式叶轮并不在被输送的介质中运动，根据流体动力学原理把需要泵送的介质引导到泵腔中，被泵送的介质从叶轮旁流过。这样，被泵送的液体介质中的长纤维或者固体物质也一起被泵送出去。而切削式叶片，能将较大的块状固体物质切碎，从而不再堵塞。　
　　确保关键设备运行,催化剂计量泵主要用于催化剂的注人，促使齐聚物在预缩聚釜、终缩聚釜内发生缩聚反应。聚酯工艺要求催化剂按一定比例注人，而且停注时间不能超过15rain。否则将使熔体粘度降低，产品质量降等。为保证催化剂泵的平稳运行，采取一些保证措施。　　
　　定期更换润滑油及磨损件,催化剂计量泵的内部主要运动件有蜗杆、蜗轮、滑块、定新活塞等。这些部件的磨损将直接导致泵流量降低或根本不上量，目前解决的办法就是定期更换润滑油、磨损件及定期清洗液压腔。　
　　严格催化剂计量泵操作规程,催化剂计量泵的启动和停车都应严格按照使用要求进行操作。在启动时，零输出开泵,待泵出口有一定压力时方可对稳压盘充氮气。避免因充氮气造成隔膜变形较大，防止隔膜破裂；提高泵输出时，要缓慢进行；停泵时，也应缓慢降低泵的输出。　
　　加强泵的维护,泵在运行期间定期巡检，检查润滑油油位、机泵声音、出口压力、氮气缓冲罐压力等。定期对泵体隔膜、氮气缓冲罐隔膜进行更换，以地防止两台泵同时损坏造成催化剂停注事故的发生。
