Automatic stepless speed regulation vertical oil pumping machine and automatic stepless speed regulation control method of oil pumping machine
Technical Field
The invention relates to the technical field of intelligent control of pumping units, in particular to an automatic stepless speed regulation vertical pumping unit and an automatic stepless speed regulation control method of the pumping unit.
Background
The stroke frequency of the oil pumping unit is the most important adjusting parameter in the production and operation of the oil pumping unit. The existing oil pumping unit mainly changes the transmission ratio of a system to realize the adjustment of stroke frequency by replacing a belt pulley. Because the number of belt pulleys cannot be infinite, each oil pumping unit can only be adjusted on a plurality of set stroke times, and meanwhile, because the belt pulleys are replaced by manual work, the stroke times of the existing oil pumping units cannot be adjusted in a stepless mode.
The stroke of the pumping unit is one of important adjusting parameters in the production and operation of the pumping unit. The traditional kowtow head mainly changes the rotation radius of a crankshaft to adjust the stroke. The specific implementation mode is that the crank pin is inserted into different hole sites on the crank to achieve the purpose of changing the rotating radius of the crank, and because the number of the vacant sites on the crank is usually only three, each pumping unit can only be adjusted on a plurality of set strokes, and meanwhile, the replacement of the position of the crank pin requires manual operation and cannot be frequently adjusted, so the stroke of the existing pumping unit cannot be adjusted in a stepless manner.
