XCMG Cooling Pump

What is the XCMG Cooling Pump

The XCMG Cooling Pump represents a sophisticated integration of hydraulic and mechanical systems designed for precise thermal regulation in heavy machinery applications. At its core, the R902551225 PUMP serves as the primary pumping unit, working in concert with the advanced PUMP REGULATOR and REGULATOR systems to maintain optimal fluid pressure and flow rates. The hydraulic circuit is managed through the R902451806 VALVE PLATE and R902462478 CONTROL PISTON ASSEMBLY, while the R983075420 GEAR PUMP provides auxiliary pumping capability.
The power transmission system features the R910994407 DRIVE SHAFT connected via the R910943545 COUPLING to the DRIVE DEVICE, transferring rotational energy to the PLUNGER CYLINDER BLOCK and CYLINDER BODY assembly. The SWASH PLATE converts rotational motion into reciprocating action through multiple PLUNGER ASSEMBLY (A10VO63) components, with the SPHERICAL HINGE and SET PLATE ensuring proper alignment. The bearing system incorporates a TAPERED ROLLER BEARING, supported by BEARING LINING elements and secured with STOP RING retention.
Precision control is achieved through the PROPORTIONAL VALVE, SPOOL, and VALVE components, with adjustment capabilities provided by the ADJUSTING SCREW and THROTTLE SCREW PLUG. The CONTROLLED PISTON and PISTON elements work in conjunction with multiple SPRING mechanisms, including COMPENSATING SPRING and SPRING SEAT assemblies, ensuring responsive pressure compensation. The fastening system utilizes various LOCK BOLT components including R902462471 LOCK BOLT and R910109606 LOCK BOLT, complemented by SCREW, BOLT, and NUT elements with HOLD WASHER and SPRING WASHER components.
Comprehensive sealing is provided through multiple O-RING, SEAL RING, and O-SHAPED SEALING RING elements, with critical shaft protection from the R909831661 SHAFT SEAL. The assembly is housed within the R902454573 HOUSING with REAR CONNECTING PLATE and BARREL sections, incorporating ADJUSTABLE PAD, LIMITER, and ELASTIC COLLAR components for precise calibration. The integration of ORIFICE, PLUG, and CYLINDRICAL PIN elements completes this sophisticated thermal management solution.
Every component within the XCMG Cooling Pump is engineered to exacting standards, delivering reliable performance and extended service life in demanding operating conditions. The sophisticated coordination of these advanced hydraulic and mechanical systems demonstrates XCMG’s commitment to precision thermal management technology for heavy equipment applications.
