Diameter adjust moment regulate pumping unit
The compound balanced pumping unit is designed and manufactured according to the standard of SY/T5044-2003 “Beam Pumping Unit”, which is based on the conventional beam pumping unit as the basic model, keeps the original structure unchanged and adds a beam Tail balance device.
Diameter adjust moment regulate pumping unit is based on the conventional beam pumping unit. The main part is basically the same as the front pumping unit. The difference is that there is no crank counterweight and the counterweight is applied at the end of the beam with varying torque. This type of pumping unit will change the crank balance to the beam balance and realize energy saving by improving the dynamic balance effect.
This type of pumping unit adopts the structure of walking beam and moment changing beam. By changing the position of the counterweight device in different quadrants, the maximum balance moment and position of the counterweight device can be adjusted in a large range.
The beam with variable torque is composed of a closed box and a counterweight device. The beam with variable torque is at the end of the walking beam, which is simple in structure, safe and reliable.The counterweight is composed of fixed counterweight and adjustable counterweight.
Compared with conventional beam pumping units, Diameter adjust moment regulate pumping unit has the following advantages：
- Simple structure and high reliability
Because the transmission mode and basic structure are the same with the conventional pumping unit, this type of pumping unit has the characteristics of simple structure and high reliability
- Simple operation and low maintenance cost
The torque transmitted by the motor and reducer of this type pumping unit is smaller than that of the pumping unit of the same specification.
- The power saving
Because of the high dynamic equilibrium rate, the power saving effect is remarkable.
4.Convenient parameter adjustment
The pumping unit is balanced by adjusting diameter pin and weight block, which is easy to operate and safe to use.
Compared with the pumping unit of the same specification, this type of pumping unit USES two lower specifications of the motor and one lower specification of the gearbox.
