By a high - pressure hydraulic oil supply system will have a certain pressure of lubricating oil to the SAE NPT standard threaded connection carbon steel junction bar manifold, Which forced for the gap of the friction surface of the deputy campaign (as in the hydrostatic slide bearing gap plane hydrostatic slide rail gap, the gap medium static pressure screw ). Not yet started the movement , the friction surface by high-pressure oil separated , forced to form a film , thus ensuring the deputy campaign can withstand a certain load conditions, completely in the state of the liquid lubrication , the lubrication is called hydrostatic lubrication.
SAE NPT Threaded Connection Carbon Steel Junction Bar Manifolds
SAE NPT Threaded Connection Carbon Steel Junction Bar Manifolds
The production processing of SAE NPT threaded connection carbon steel junction bar manifold:
In-house CAD/CAM according to drawings or samples
Outside processing for shape
Production of cut-off operations and plating to keep the materials parallel to get the cube
Precision machining to produce as the models designs
Production of CNC turning and milling reaching the threads precision
Secondary operations
Center less and thread grinding
Heat treatment if required as various working conditions
Broaching for the holes with modeled in order to keep the good dimensions
Threading
Burrs movement and tested with high pressure for materials stress
Ultrasonic clearance
Surface treatment
Packing before delivery
