Rotary Swivel - High Strength Alloy Steel, Reliable High Pressure Sealing System | Efficient Weight Bearing And Fluid Introduction

We are a prominent Exporter & Manufacturer of Rotary Swivels in Gaoyou, Jiangsu, China.

1. Swivel overview
The swivel is the link between the rotation system of drilling machine, the lifting system and the circulation system, on the one hand, it bears all the weight of the drill column in the well, hangs drill column and ensures the free rotation of the drilling tool, and on the other hand, it is connected with the rotary hose, introduces the high pressure drilling fluid into the rotary drill stem to wash the well in the well bottom.

2. Function and operation requirement of swivel
2.1 Swivel function: the rotary hanging drill stem bears a great amount of and all the weights of the drilling tool; it introduces high pressure drilling fluid into the rotary drill column and it is the intersection parts of three working units (lifting unit, rotating unit and circulation unit).

2.2 Operation requirements of swivel: the main bearing of the swivel must have sufficient strength and life; high pressure drilling fluid sealing system (or washing pipe assembly) must work reliably, have long life and quick and easy replacement and good oil seals; each bearing parts (including lifting loop, shell and central tube shall have sufficient strength and rigidity).
