Single screw pump is a pump loss, economic performance, high pressure and uniform, uniform flow, high speed advantages, these products can not only transport lubricants, delivering fuel, but also transport a variety of oils Classes and polymers and for the transport of viscous body. However, as its working intensity increases, the probability of a single screw pump failure also increases. What are the problems of a single screw pump at present? What are the solution to the problem? Single screw pump failure analysis and solutions 1, the shaft power increased dramatically: Failure Analysis: ①discharge pipe plugging; ② screw and pump sets of serious friction; ③ medium viscosity too much; solution: ①stop the pump to clean the pipeline; ② Maintenance or replacement of parts; ③ the media warming; 2, the pump does not absorb oil: Failure Analysis: ①suction blockage or leakage; ② suction height exceeds the allowable suction vacuum degree; ③ motor reversal; ④ medium viscosity is too large ; Solution: ①maintenance suction pipe; ② reduce the suction degree; ③ change the motor steering; ④ medium heating; 3, pressure gauge pointer fluctuations: Failure Analysis: ①suction pipe leakage; ② safety valve is not adjusted So that when the safety valve open to close; ③ work pressure is too large, so that the safety valve open when closed; solution: ①access suction pipe; ② adjust the safety valve; ③ adjust the working pressure; 4, flow down: failure Analysis: ①suction enough head; ② inhalation of pipeline blockage or leakage; ③ screw and pump wear; ④ safety valve spring is too loose or valve and seat contact laxity; ⑤ motor speed is not enough; to solve Methods: ①increase the surface; ② suction pipe sucking, plugging, leakage; ③ serious wear and tear should be replaced parts; ④ adjust the spring, grinding disc and valve seat; ⑤ repair or replace the motor; Power surge, the pump does not absorb oil, pressure gauge pointer fluctuations, the decline in flow rate of these types of fault analysis, we can conclude that the same fault occurs for a variety of reasons, this result is likely to delay the user to solve the problem in time , But also affect the user experience of the product experience, single-screw pump failure is indeed a thorny issue, this road needs us to continue to struggle first.
