What is the difference between Drilling Cutting Screw Conveyor and ordinary screw conveyor in China?
Many people already know about screw conveyors, but Drilling Cutting Screw Conveyor, presumably many people don’t know too much. What is the difference between Drilling Cutting Screw Conveyor and ordinary screw conveyors?
In china, Drilling Cutting Screw Conveyor is divided into two types: shaft and shaftless. For the characteristics of sludge, shaftless spiral blades are generally used. However, for relatively thin mud, it is recommended to use a shaft spiral when conveying. The pipe shaft is a single root without lifting. The pipe shaft needs to be processed by a grinding machine and quenched to ensure hardness and concentricity.
Ordinary shaftless spirals generally use horizontal reducers, shell carbon steel, thickness 4mm; blades are made of 16Mn, thickness is about 20mm, linings are made of wear-resistant nylon material, ordinary motors are sufficient, and external painting is not required.
Drilling Cutting Screw Conveyor generally adopts a vertical reducer. According to the classification and installation requirements of the Drilling Cutting Screw Conveyor discharge port device, the shell has lifting holes. Because the petroleum operation equipment is not fixed, it will always move. The external lifting parts must be equipped with ; The shell is generally made of carbon steel with a thickness of 6-8mm; the blades are made of 16Mn with a thickness of 22-28mm; the liner is made of 16Mn steel plate, which is highly abrasive due to drilling debris and sludge; the nylon liner is not durable , Has been changed to a rigid liner; the motors are all explosion-proof motors, and the cover plates are steel gratings or no cover plates; the exterior paint is epoxy hull paint. The safety level is much higher than that of U-shaped screw conveyor installation safety measures.
The above will talk about the difference between Drilling Cutting Screw Conveyor and ordinary screw conveyor. I hope it will help you in your choice.
