Key parts of oil drilling machine
一、BU shaft parts
 |
 |
- Material for 15-15HS high strength non magnetic stainless steel or high temperature nickel based alloy Inconel 718
- Material by heat treatment, high strength, high toughness, difficult cutting processing materials, processing easy deformation, optimization processing order to offset or in the control range
- API taper thread, Spiralock self locking screw
- Special fixture machining space inclined hole, good rigidity, high reliability
- The inner face of the large and medium hole is more than one small hole, the special gun drill jig is used to ensure the position relationship between the holes.
- Three 100% coordinates (CMM) final detection
二、DCLong axis parts
- Material for 316L austenitic stainless steel or aluminum bronze alloy
- Complex structure, thin and thin wall, more than 2000 processing characteristics
- Position control of the entire range of control hole 0.3mm
- The total length of 2500mm to 4500mm, the length of the direction of the size of the heat affected significantly
- 100% Three coordinates (CMM) final detection
三、Key parts for piston pump
The main parts for oil field acidification, cementing, fracturing, sealing well and other intermittent operation with high pressure, high displacement, high power piston pump in the crankshaft, connecting rod, cross head
