chopper combine pump repair

The hydraulic pump of a chopper combine is typically an axial piston or vane type, designed with a flow capacity between 80 and 120 liters per minute. It operates within a working pressure range of 200 to 250 bar and is responsible for supplying hydraulic oil to systems such as lift cylinders, steering, and the feeding mechanism of the cutter. Proper pump type selection and attention to flow capacity are critical to prevent efficiency loss and overheating of the hydraulic oil during harvesting operations.

The installation location of the chopper combine hydraulic pump is usually at the front of the engine, aligned with the power transmission shaft. The connection is often made through direct coupling or flange mounting to ensure mechanical power transfer without energy loss. At this position, high-pressure hoses and return lines to the hydraulic reservoir are attached, requiring precise sealing to prevent leakage and pressure drops. Any shaft misalignment can lead to increased vibration and significantly reduce pump lifespan.

The repair process of the chopper hydraulic pump includes disassembling all components, thoroughly cleaning them, inspecting piston and vane wear, and checking bearing tolerances with 0.01-millimeter accuracy. If scratches or dimensional changes greate

Casappa hydraulic pump repair

The hydraulic pump of the backhoe loader brand CASAPPA is one of the key components of the hydraulic system, responsible for supplying the required flow and pressure of hydraulic oil. These pumps are usually gear or piston type, with flow capacities ranging from 60 to 120 liters per minute and operating pressures between 180 and 250 bar, providing high efficiency in energy transmission. The precise gear design and optimized sealing system significantly improve performance, reduce leakage, and increase the overall service life of mechanical components.

The main reasons for CASAPPA hydraulic pump failure are oil contamination, cavitation, overload, or high operating temperatures.

wire rope with polypropylene core PP

The core of wire rope is one of the main components of steel wire rope that plays an important role in determining the type of wire rope and its use.
Around the core of the steel wire rope are strands made up of a number of wires.
Fiber core steel wire ropes are often made of polypropylene, hemp and sisal fibers.
The structure of steel wire ropes with polypropylene core is usually 6 strands or 8 strands.
PP core steel wire ropes are mostly used in marine industries and are very suitable for marine uses due to lack of water absorption and weight gain and are also suitable for floating use on water.
In general, steel wire ropes with plastic cores weigh less than others.

PP marine rope

Marine rope is produced from polymer compounds to have proper resistance in contact with corrosive substances in sea water that are in the form of various minerals and salts. The most widely used polymer compounds in the production of marine rope are polypropylene PP, which has very low affinity due to its heavy molecules and does not corrode when in contact with salty sea water. Another reason for using polypropylene ropes in marine applications is the lower density of these compounds compared to sea water. This causes the sea ropes to be placed on the surface of the water and visually lead to a better view and not get caught among the propellers of ships and lanyards.

PP marine ropes

PP marine ropes are strong type of rope that is used as replacement for steel wire rope and chain due to much higher resistance against salt water. marine ropes are not only made of PP and synthetic materials but also a very common, strong and resistant type of marine rope is Manila rope that comes mostly from Philippines and therefore has the name taken after the capital city of this country. PP marine ropes are highly flexible and do not pick extra weight once exposed to sea water.
