转子泵出现没有流动的原因及解决方案
Causes and solutions of no flow in rotor pump
没有流动但泵转动
No flow but pump rotation.
原因:转动方向错误
Cause: wrong direction of rotation.
解决办法:改变转动方向
Solution: change the direction of rotation.
没有流动,泵不自吸
Without flow, pumps do not suck.
原因:进口管路阀门被关闭、进口管路堵塞或流动受限制、由于密封或管路连接不好,空气泄露入系统、泵速度过慢、在停泵期间,液体从系统内被排掉,气体锁住,流体气化或挥发,或停泵期间气体从溶液内跑出,转子间隙过大,泵磨损,净进口压力过低,进口真空系统,泵启动初始,大气反吹,阻止泵产生足够的压力差使流体流动
Reasons: Inlet pipeline valve is closed, inlet pipeline blockage or flow restriction, due to sealing or poor pipeline connection, air leakage into the system, pump speed is too slow, during pump shutdown, liquid is discharged from the system, gas lock, fluid gasification or volatilization, or during pump shutdown gas from the solution run out, rotor clearance Excessive, pump wear, net inlet pressure too low, inlet vacuum system, pump start-up initial, atmospheric back-blowing, prevent the pump from generating enough pressure difference to allow fluid flow
解决办法:开启阀门,清洗管线、过滤器,更换密封,检查管路有否泄露,增加速度。在进口管道注入流体也许可以启动,使用底阀可能永久解决启动问题,使用底阀或止回阀,手动或自动把空气从泵或附近管路排出,增加泵速,使用底阀以促进启动,检查NIPA、NIPR,重新计算系统,必要时改变管路设计,在出口管路上安装止回阀
Solution: Open the valve, clean the pipeline, filter, replace the seal, check whether the pipeline leakage, increase the speed. Injecting fluid into the inlet pipe may start, using the bottom valve may permanently solve the start-up problem, using the bottom valve or check valve, manually or automatically discharging air from the pump or nearby pipeline, increasing pump speed, using the bottom valve to facilitate start-up, checking NIPA, NIPR, recalculating the system, changing pipeline design if necessary, at the outlet. Check valve installed on pipeline
没有流动
No flow
原因:安全阀没有调校好,或阀座被卡住,流体经过安全阀旁路循环流动
Cause: the safety valve is not adjusted, or the valve seat is jammed. The fluid flows through the bypass of the relief valve.
解决方法:调节或清洁阀门
Solution: adjust or clean valves.
