INTRODUCTION |
3NB F Power end
¢Å The frame is a welding structure with steel plate, high
strength, rigidity and light weight.
¢Æ Adopt herringbone gear drive, smooth running.
¢Ç The crankshaft is made of alloy steel, the crosshead
guide are replaceable.
¢È Adopt roller bearing, enhance running smooth and
loading capacity.
¢É The seal component for extension rod is a unique and
advanced structure, have excellent seal performance.
¢Ê At the important locations such as gears, bearings and
crosshead etc. we adopt forced and splash lubrication mode
¢Ë Adopt the Spiralock's nut, convenient to assembly and
teardown.
3NB F Fluid end
¢Å The fluid cylinder are straight pass through structure,
can make the fluid flow smoothly, volumetric efficiency higher
and structure compact.
¢Æ The three fluid cylinders are interchangeable.
¢Ç The cylinder head and valve pot cover can be rapidly
tightened, convenient to assembly and teardown.
¢È The suction valve and discharge valve can be
interchanged
¢É The piston and liner bore are open wide structure,
