With plenty experience of researching water supply pumps, this project was chosen according to the market. It is for life water supply, agriculture irrigation water saving, industryfire-fighting water supply and water schemes of the chemical enterprise. The main technicaltheory is first we send the pressure sign als collected
by the pressure sensor which is fixed at the exit of the pump to the computer, then by PID calculating ,turn them into electrical signals to drive the electromotor ,we can
realize the frequency conversion, velocity regulation and energy saving. The main performance data are the frequency conversion, velocity regulation, level pressure variable,automatic noman operation, water supply precision is in the range of rated pressure.
The tolerance is 5%; malfunction diagnosis, automatic warning, electric cutoff memory;
the pressure setting , energy saving is more than 40%. After the index of the provincial New Production Checking Consultation Center at home, they did not fine
the same project and they thought it is advanced at home. Its success is a revolution in the history of the pump development. It is important for the water and energy saving,and it can bring us considerable profit and social influence.

1、The technology files of the product sample are correct, complete. They reach the relative standard of the line and can be used to produce.
2、The data in the inspection report (No.2001-2457) of the National Fixed Fire-fighting System Quality Inspection Center which is authoritative are exact
and can be used as the critical gist.
3、The Index and the Report shows that the performance and technology data of the XZX series intelligent pumps reach the standards of the line,
and meet the requirements of the design. The technology is advanced, reliable and patented.
4、With the advanced technologies of the new frequency conversion and velocity regulation, hazy control technology, sensor technology, malfunction diagnosis technology and information preferential deal with.XZX series intelligent pump has
realized the function of leve lpressure water supply, automatic no-man operation,
malfunction diagnosis, automatic inspect, voice and light warning. With its high
intelligence, the pump can be used to fire-fighting water supply and life water supply to save water and energy.
5、With its advanced equipments, complete inspection way and correct source proportion, Zibo Three Pumps Industrial Co.,Ltd has carried out the ISO9002 and is qualified
to produce in batch。The Appraisal Committee approved the developmentof XZX series
intelligent pump is successful. It is advanced for its level pressure control, malfunctiondiagnosis, automatic inspection and make up the blank of this line at home.
With its distinct economic profit, social influence and bright future, it is agreed to produce in batch. They also suggest get it more artistic and produce it in batch to meet the expanding market.
