Doosan dx225lca hydraulic pump

Types of Doosan DX225LCA hydraulic pumps

There are many types of hydraulic pumps for excavators. Generally, hydraulic pumps can be divided into three categories based on operating principles: gear pumps, variable displacement pumps, and piston pumps. The Doosan DX225LCA hydraulic pump belongs to the latter two categories.

• Gear pump: Gear pumps use two or multiple rotating gears to change the volume of fluids. Their gear teeth separate and rejoin, which enables the liquid to be sucked in and expelled. As the pump's flow is entirely dependent on the rotational movement of the gears, this means the output is normally constant. This makes gear pumps suitable for low-pressure and high-flow applications where a consistent flow is required, such as in lubricating systems. However, gear pumps may not be very effective in dealing with varying pressures and complex tasks.
• Piston pump: Piston pumps use pistons moved by hydraulic pressure or electric motors to change the volume of fluids. They generate force that pushes the fluid in or out through valves and cylinders. Piston hydraulic pumps are able to develop high pressures and offer adjustable flows by changing the motor speed and piston numbers, which makes them appropriate for excavators requiring a lot of power and precise control.
• Variable displacement pump: The flow of variable displacement pumps can be changed by altering the angles of swash plates or changing the orbit of the motor, which are normally controlled by pressure compensators or electronic sensors. They can provide constant pressures and higher efficiencies, making them suitable for large excavators. Furthermore, with their ability to adjust to different working circumstances and save energy by reducing motor speeds, variable displacement pumps can extend the excavator's servicing life.

DX225LCA Doosan hydraulic pump specification and maintenance

Specification

The DX225LCA hydraulic pump has the following specifications:

• Flow rate: The Doosan DX225LCA gear pump flow rate is the amount of hydraulic fluid it can move per minute. It is commonly expressed in liters per minute. It is an important property. It determines how much hydraulic power the excavator can generate.
• Pressure rating: Every hydraulic pump has a specified operating pressure. It is the maximum pressure at which the pump can function. This pressure rating affects the force the hydraulic pump can generate.
• Power requirement: This is the amount of engine power the excavator needs to operate the hydraulic pump. It is specified in kilowatts or horsepower.
• Mounting type: Hydraulic pumps use different mounting methods depending on the excavator model. It could be a flange, group, or any other mounting method.

Maintenance

• Regular inspection: Conduct regular inspections of the hydraulic pump and its connection to the hydraulic system. Users should inspect the hoses, fittings, and joints for signs of leaks. Repair any hydraulic fluid leaks immediately to prevent wastage.
• Check oil level: The performance of the hydraulic pump depends on the operating and reservoir oils. Check the oils regularly to see if it’s at the correct level. Top it up if the oil goes below the required level. Also, make sure the oil is of the right grade and clean. If not, perform an oil change.
• Monitoring performance: Monitor the hydraulic pump’s performance regularly. Take note of any changes in flow rate or operating pressure. Listen for any unusual sounds. Address any issues promptly because they could lead to more serious damages down the line.
• Replace hydraulic filters: The hydraulic fluid filter’s role is to prevent contaminants from getting into the pump. A clogged filter will affect its functionality and damage the pump in the long run. Remember to replace the filter regularly to maintain optimal function.
