Stainless steel flexible rotor pump

Features of stainless steel flexible rotor pump: The pump body is made of stainless steel precision casting, and all flow metal components are made of stainless steel. The viscosity of the conveying medium can reach 5000 CP. It can transport liquid containing gas, liquid and foam without air lock. Can transport media containing suspended soft and hard particles. The gentle movement of the rotor does not damage the medium that is sensitive to shear. The flexible rotor pump operates without metal contact and does not produce sparks. Beautiful appearance and easy maintenance. The self suction performance and strong adaptability to working conditions of this pump make it suitable for various industrial applications. Perform liquid suction and drainage, sampling, and transportation of various fluids and semi fluids in bucket pouring, warehouse sweeping, and underground tanks. Widely replacing centrifugal self priming pumps, submerged pumps, gear pumps and other pump types. Industry - a wide range of media including weak inorganic acids, acids, bases, salts, oils, alcohols, ketones, esters, etc

Stainless steel flexible rotor pump is a volumetric pump that vacuum suction and extrusion discharge liquid. All flow components of the stainless steel flexible rotor pump are made of stainless steel casting, and the rubber rotor operates gently, which not only integrates multiple functions, but also has some characteristics, including dry self suction ability and strong conveying ability. It can ideal transport shear sensitive, medium to low viscosity, and suspended particle containing fluids and semi fluids

Fault analysis and solutions for stainless steel flexible rotor pump

1. The rotor pump does not run

Fault analysis: The motor power supply is not connected;

; Motor damage; The reducer is damaged; Bearing damage; The rotor is stuck

Solution: Replace the motor; Repair or replace the reducer; Replace bearings; The rotor or rotor chamber and chamber cover

2. No discharge, but the motor is running

Fault analysis: The motor's direction is opposite to the direction mark;

; The reducer is damaged; Coupling damage; Close the inlet and outlet pipeline valvesSolution: Open the inlet and outlet pipeline valves; Dredge the inlet and outlet pipelines; Exhaust and plugging; Adjust or clean the protective valve; Add materials; Repair or replace the reducer

3. The rotor pump operates normally, but the flow rate is very small

Fault analysis: The speed is too low;

; The reflux valve is opened; The opening degree of the inlet and outlet pipeline valves is small; Blocked pipeline filter screen; Excessive pressure inside the discharge pipeline; Blocked pipeline filter screenSolution: Increase the rotational speed; Adjust the opening degree of the reflux valve; Open the inlet and outlet pipeline valves; Sealing of leaks or pipelines; Clean and unblock the pipeline filter screen

4. There is gasification phenomenon in the discharge material

Fault analysis: The filter screen, feed valve, and feed pipe are blocked;

; The feeding pipeline is too thin, the feeding pipeline is too long, and there are too many elbows and valves; The filter screen is too thin; The feed pressure is too lowSolution: Clean and dredge the filter screen, feed valve, and feed pipeline; Adapted filter screen for phase change; Using high-level feeding; Reduce the speed or purchase a suitable rotor pump again

5. Excessive noise during the operation of the rotor pump

Fault analysis: The reducer is damaged;

; Excessive rotational speed; Bearing damage; Coupling misalignment; Rubbing between the rotor, rotor chamber, and chamber cover; Excessive vibration in the inlet and outlet pipelinesSolution: Repair or replace the gearbox; Reduce the speed; Replace the coupling; Rotors, rotor chambers, and chamber covers; Reduce the speed or choose a suitable rotor pump again
