Description

ENERGY SAVER FOR OILFIELD PUMPING UNIT Principle Operational characteristic of oilfiled pumping unit consumes large amount of power. When pump apparatus is assembled well with a certain stroke length and the piston diameter, and frequency also has been completely fixed, so the working capacity of oilfiled pumping unit becomes constant. For the change of load in oil well, the fixed capacity of oilfiled pumping unit could not be in response to changing load in the process of operation, leading to excessive working capacity. Therefore, oilfiled pumping unit is always in a state of half-load or light load. For this situation, XINWEILI develops the energy saver for oilfield pumping unit, which adopts intelligent microcomputer controlled technology, monitoring the working order and judging the actual load of motor to choose proper power complied with the changing load and motor torque. The active power of consuming electrical power has been greatly improved and pump operation is more reliable. What’s more, the energy saving optimized software can judge pumping emptiness exactly and automatically control the work, so as to increase oil output and save a great deal of electrical power. I. Features i) Energy saving ratio is up to %*0~%*0 ii) It is intelligent controlled and has table performance. II. Technical parameter i) Working temperatureï&frac*4;š**0℃ - *0℃. ii) Relative humidity:≤%*0 (without dew) iii) Input voltage: **0Vï&frac*2;ž**0V iv) The surge endurance: the standard of IEEE**2 III. Applicable devices Various types of oil pumping devices in big and small size.
