Hydraulic pump is the primary power source of all the hydraulic systems of excavators.

Excavator hydraulic pump is the heart of construction machinery. If your excavator hydraulic pump is out of order or faulty, then various hydraulic parts cannot generate power and make them non-operative. Hydraulic pump is the primary source that develops pressure essential for excavator hammer.

21. What is the role of the piston in excavator hydraulic pump parts?

The piston in excavator hydraulic pump parts is one of the main parts and also the most important. The piston is located in the cylinder block, which is between the driveshaft and pump cylinder. The drive shaft plays the role of transmitting torque and movement from the hydraulic motor to the pump cylinder to suck oil into itself and discharge it from its outlet port.

The piston has three leading roles in the hydraulic pump parts.

• One is to regulate the amount of fluid that passes through the system,
• The second is to act as a seal within the cylinder, preventing leakage, and lastly, once the fluid passes through the piston, it provides force (as it is forced back into the cylinder) which pushes an object against a surface.
• This third role of pushing an object back against a surface is known as a shock load.

22. What do you mean by pressure created by excavator hydraulic pump parts?

First of all, excavator hydraulic pump parts can create different forms of pressure, such as low-pressure and high-pressure fluid flow. It is undeniable that when a hydraulic pump works, it will create a certain pressure.  This pressure is significant for the operational status of the whole machine. The pressure created by excavator hydraulic pump parts can be divided into mechanical and physical force.

Mechanical pressure is the power generated by the engine, finally driving the rotating shaft and then pumping by excavator hydraulic pump parts. The physical pressure is exerted on the material being excavated by a vibrating plate or cutting edge, which means that the greater the force of impact energy on a surface, the greater the pressure value.

23. What causes the failure of excavator hydraulic pump parts?

Failure of the excavator hydraulic pump parts directly affects the construction efficiency because the excavator hydraulic pump is one of the most critical components in an excavator; effectively involving its efficiency depends on how well it operates. Excavator hydraulic pump parts like the driveshaft can wear out and fail due to improper or harsh machine use.

Using the excavator with a worn-out drive shaft can cause severe damages and accidents. Also, the power cylinder block is a critical part of an excavator. The cylinders need to be regularly checked for internal damage and cracks and replaced at the first sign of wear or damage. The ball guide is another part that is crucial to maintain the proper functioning of an excavator.

24. What is the reason behind overheating in excavator hydraulic pump parts?

Excavator hydraulic pumps overheat mainly because of the following reasons. First, there is little lubrication on the seal rings and valve plate during the movement of the seals. The surface of the seal rings and valve plate wears and generates heat, which leads to overheating.

Secondly, in some excavators, the drive shaft tooth meshes are not in good condition. That is, they have worn and tear on them. This makes the transmission torque overload, and there is too much pressure on the drive shaft. The drive shaft transmits pressure to the seal ring or valve plate, thereby resulting in overheating.
