Message of Chinese oscillatory mechanically-laid web: As the development of the energy-saving job that decrease a platoon, production company of equipment of Bohai Sea oil bear the prospect of market of energy-saving electric machinery that heart department amounts to a company to produce is valued.
Bear heart department amounts to a company is domestic only accords with SY/T5226 and the manufacturer home of 6636 two old standards completely. In the API attestation list that published 2008, bear heart department is amounted to is the company that world only acquires access of API 11L6 meeting mark. Up to by this year June, department amounted to design of company research and development to give the electric machinery of 246 kinds of different specifications, have production of 138 kinds of devoted batch among them.
Use tall, freeboard to turn poor rate electromotor replaces common electromotor to procrastinate move pumping unit of walking beam type to have a lot of advantages. It is section report above all. Hundreds well experiment checks data to make clear, use energy-saving model electric machinery 100 meters ton juice power consumption can drop 15 ％ come 30% , rate of average length report achieves 20% above, apparent to improving systematic result. Daqing oil extraction sets an example south 5 factories apricot 55 device that the area tests year section report 104 kilowatt of 54.16 × hour. Show according to investigation, freeboard turns investment of equivalent of poor rate electromotor yields comparing is 1 ∶ 7.7, energy of its equivalent section divides craft kind the first rank outside measure.
It is OK next reduce pair of pumping unit reducer casing mar. Reducer casing is the highest component in pumping unit. This kind of electric machinery can make reducer casing torque obtains the least value, the fatigue that reduced gear greatly is destroyed, reduce the accident making a tooth-like part of anything of reducer casing, reducer casing can reduce an API progression. China north oil field is smoked 400 times in fork river collect change in wildcat with 200 CJT device, in a year of half dog in statistic, only one makes a tooth-like part of anything. In the meantime, should match only reasonable, this kind of electric machinery can be protected automatically when reducer casing overload stop machine.
It is dependability thirdly strong. Because electric machinery deserves to go up 24 hours to run in pumping unit, reliability is very fundamental. Electric machinery life basically depends on insulation life, because heat-resisting order and degree is high,department amounts to electric machinery, movement can have for a long time below 155 Celsius. Electric machinery circles inter block to have protection in electric machinery when the design, from go up at all avoided electric machinery to be burned.
Superior performance makes department amounts to electric machinery to apply extensively in domestic oil field not only, and batch exports more than 10 nations such as Indonesian, Syria. According to statistic, up to this year first half of the year, the department that for home each oil field uses amounts to electric machinery to already had many 30 thousand, every annual section report charge is in on average 10 thousand yuan of above.
