Mechanical and electronic transformation self-suction pump realization of automatic operation
【 abstract 】 this topic at with technical transformation of the way to resolve the post office self-suction pump is because of installation reason, water pump mechanical and electrical design defects and problems that can't satisfy the production operation needs, can't achieve or fast to working condition, can't achieve self-priming pumps "a drainage", "lifelong self-priming" automatic operation, high failure rate run unstable and so on many kinds of problems for improvement.
Strive to this topic (or technical transformation) realize self-suction pump basis without manual intervention process conditions, fully automatic operation, and found out the high failure self-suction pump, frequent source and correct, and the relevant materials in light of their own conditions for mechanical and electrical equipment selection and experience requirements made some of their own views.
Installed in the pool page 4 meters high above the continuous drainage without seal self-suction pump, the test and operation system more than 1 year since, equipment operation always exists:
1, every time all need someone to start in irrigation equipment, equipment start can't writes.
After repeated testing and analysis the equipment is found not to stop after the operation, equipment in the body cavity standing back to sink, in rapid backflow, again started in the body cavity water shortage, need to infuse water, after a full study of the high point of water pipeline will add electric air control valves realize when the pump is going to stop vacuum damage, further will pump water pipe and connection position up 100 mm height. Problems are resolved.
2, equipment of water booster too slow, equipment after the launch of steadily in irrigation cases, basic need 1 hour to be effective water pressure slow rise to basic conditions.
After continuous commissioning and analysis found that equipment bibulous pipeline pipe diameter is too large, equipment design can't satisfy the vacuum suction ability, will suction pipe by DN200 DN100 instead, problem solving.
3, insufficient capacity (one of the machine), can't satisfy the needs of the flow of head and.
After the careful testing found that pump is sounding laying cable diameter deficit, change after cable problems can be solved.
4, equipment failure too high, frequent the problem of maintenance.
