Equipment, accounts for 90% of total amount or so, and power consumption accounts for 40% of oil field total electricity consumption or so.The rotary inertia of beam pumping unit
Greatly, loading rate is big, and is heavy-load start.
Traditional beam pumping unit passes through belt drive by ordinary three-phase synchronous or high slip threephase asynchronous
Reductor drives operation.Threephase asynchronous starting current is big, impacts larger to network load, and actual pumping operation process
In due to load change it is violent, motor is typically in half load or the operation of more low-load, now the efficiency and work(of asynchronous motor
Rate factor is all very low；Additionally, skidding also often occurs in the driving belt between motor and reductor, affect equipment normal
Operation.In sum, traditional beam pumping unit type of drive has that complex structure, trouble point are more, fault rate is high, efficiency is low
The shortcomings of.
