Kawasaki K5V280/K5V140/K5V160/K5V200/K3sp36cHydraulic Pump Spare Parts
K5V Kawasaki pump is widely used in modern medium to large hydraulic excavators. It is the "heart" of the excavator hydraulic system, and its performance directly determines the overall work efficiency of the machine.
Due to its wide application, there is a huge market demand for K5V accessories. Providing high-quality replacement parts is crucial for ensuring the performance, efficiency, and lifespan of excavators and other equipment.
1, Core parts product introduction
The structure of K5V pump is extremely precise, and its maintenance accessories mainly include two parts: pump body accessories and regulator (variable control system) accessories.
A. Core accessories of pump body:
1. Valve Plate/Port Plate
·Function: Core fixed friction pair, precise flow distribution, control the switching of high and low pressure oil.
·Features: Usually made of high-performance copper alloy with wear-resistant coating on the surface. The distribution plates of the front and rear pumps are usually different and cannot be interchanged.
2. Cylinder Block/Barrel
·Function: It accommodates the plunger and rotates, serving as the main body of the working chamber.
·Features: Made of high-strength copper alloy, with extremely high precision requirements for plug holes. The cylinder blocks of the front pump and the rear pump are usually different.
3. Piston and Slipper Assembly
·Function: Perform reciprocating motion inside the cylinder to complete oil suction and pressure.
·Features: The plunger is made of precision ground quenched steel, and the bottom of the sliding shoe is made of wear-resistant material. It is one of the most easily worn moving parts inside the pump.
4. Shaft Seal
·Function: Prevent hydraulic oil leakage from the extended end of the spindle.
·Features: Usually a double lip oil seal (one oil proof and one dust proof). This is the most common leakage point and needs to be replaced regularly.
5. Bearing
·Function: Support the spindle and withstand radial and axial forces.
·Features: High precision and high load capacity bearings are used, and their state directly affects the smooth operation of the pump.
6. Seal Kit
·Function: Includes all static seals such as O-rings and sealing rings.
B. Regulator Core Accessories: The K5V regulator is the essence of its technology, with a complex structure and precise accessories.
2, Product features and advantages
·High precision compatibility: strictly manufactured according to the original dimensions and tolerances of Kawasaki K5V, ensuring a perfect match with the pump.
·Material guarantee: The core friction pair is made of high wear-resistant materials equivalent to the original factory (such as special copper alloy, surface coating) to ensure its service life.
·Performance recovery: Professional maintenance using high-quality accessories can effectively solve various pump failures, such as:
·The whole machine operates slowly and weakly (due to insufficient pressure and flow)
·Excavator drops speed after being heated (volume efficiency decreases)
·Abnormal noise and shaking (large component wear and clearance)
·External leakage (aging of oil seals and seals)
·Cost effectiveness: Compared to purchasing a new pump assembly, the maintenance parts plan can save a lot of costs and has significant economic benefits.
3, Application scenarios
These accessories are specifically designed for:
·Hydraulic excavator: This is the main application area of K5V pump, which is used by almost all mainstream brands of medium and large excavators.
·Other construction machinery: such as large loaders, rotary drilling rigs, etc.
Used for K5V pump:
·Regular preventive maintenance
·Fault repair (such as the performance issues mentioned above)
·Equipment overhaul
