Structure Features
1. The pump is horizontal triplex single-acting piston pump
2. Adopting herringbone gear transmission,low transmission noise,no axial force,more
durable bearings
3. Super-large crankshaft box which was welded by steel plate,eliminating the stress,good
rigidity,high strength,good-looking appearance
4. Hydraulic cylinder is alloy steel forging, cut-through cylinder,namely, valve on the valve
structure , reduced the cylinder volume, improved the volumetric efficiency;
5. Adopting rear-mounted liner structure, shortened the matching length of liner and liner seat,easy to disassembly
6. Circulating water pump cooling system can improve the service life of liner and piston
7. Adopting pneumatic tube clutch,easy to operate and repair
8. Power end adopts the combination way of forced lubrication and splash lubrication
which equipped with oil guide box device to make the lubrication of friction pair and
bearings more reliable
