Drive Rod for Screw Pump - Higher Tensile Strength
Specifications
Drive Rod for Screw Pump Used in Electric Heating Device
Introduction
Drive rod for screw pump is a special sucker rod, which has higher tensile strength of the sucker rod body and more stable connection. The drive rod for screw pump can prevent the fracture of sucker rod. It is more safe and stable than the common sucker rod.
The drive rod for screw pump can be divided into solid drive rod and hollow drive rod. According to the connection type, it can be divided into straight thread drive rod and wedge left-hand thread drive rod.
Drive rod has solid drive rod and hollow drive rod.
Drive rod has straight thread and wedge left-hand thread connection type.
Specifications
- Material: 35CrMo.
- Type: solid drive rod and hollow drive rod.
- Connection type: straight thread connection and wedge left-hand thread.
- Length:
- 0.75m - 3m for drive pony rod.
- 8m - 11m for drive rod and drive polished rod.

Wedge left-hand thread drive rod connection.
Features
- Higher tensile strength of the whole rod. All parts of drive rod for screw pump is manufactured from 35CrMo and through the production of hardening and tempering, which ensure the good mechanical property.
- Higher yield strength. Heat treatment technology can improve the yield strength and twist resistance of the drive rod.
- Wedge left-hand thread structure has better torque resistance which transmit the torque through wedge structure which can prevent the fracture and breaking.
- The straight thread structure has large thread diameter than the common sucker rod which can broaden the bearing torque surface, which can prevent breaking of the drive rod and improve the service life of the drive rod.
Applications
- The drive rod for screw pump is specially designed for screw pump.
- The drive rod can be used in the hollow sucker rod electric heating device to explore high pour point, high viscosity and high wax content crude oil.
