WARRANTY

During the warranty period, if the hydraulic equipment fails to operate due to a defect in materials or workmanship under normal use and maintenance conditions as described in the user manual, the manufacturer will repair or replace the defective parts or the entire unit at its discretion, free of charge.
The manufacturer will cover the cost of labor and necessary replacement parts required to restore the hydraulic equipment to proper working condition.
The warranty covers the main hydraulic components including the pump, cylinders, valves, and hoses, provided that the damage is not caused by external factors not related to product quality.

FAQ

1.What is hydraulics?

Hydraulics is a branch of science and engineering that deals with the mechanical properties and use of liquids, especially when under pressure. It uses pressurized fluid to generate, control, and transmit power.
2. How does a hydraulic system work?

A hydraulic system works based on Pascal's law. A pump creates pressure in the hydraulic fluid. This pressurized fluid then acts on pistons or other actuators. When a force is applied at one point in the fluid, the pressure is transmitted equally throughout the system, causing movement or work to be done. For example, in a car's braking system, when you press the brake pedal, it forces fluid in the lines to apply pressure to the brake calipers, which then squeeze the brake discs to slow down the vehicle.
3.What are the common applications of hydraulics?

Construction Equipment: Hydraulic systems are used in excavators, bulldozers, and cranes for lifting, digging, and moving heavy loads. The powerful and precise control offered by hydraulics is crucial for these operations.
Automotive Industry: In addition to brakes, power steering systems often use hydraulics. Some vehicle suspensions also use hydraulic components to adjust ride height and damping.
Aerospace: Hydraulic systems are used in aircraft for landing gear operation, flight control surfaces actuation, and braking.
Industrial Machinery: Presses, machine tools, and conveyor systems may use hydraulics for their operation.
4.What type of fluid is used in a hydraulic system?

Most commonly, hydraulic oil is used. There are different grades and viscosities depending on the application and operating conditions. For example, in cold climates, a thinner oil with better low-temperature flow properties may be needed. Synthetic oils are also used in some cases where high performance or specific properties such as fire resistance are required.
5.How often should the hydraulic fluid be changed?

The frequency of fluid changes depends on several factors:
Operating Hours: In heavy-duty industrial applications, the fluid may need to be changed every 2000 - 4000 hours of operation.
Contamination: If the system is exposed to excessive moisture, dirt, or other contaminants, more frequent changes may be necessary.
Type of Equipment: Some sensitive or high-precision hydraulic systems may require more frequent fluid changes compared to less critical ones.
6.What happens if the hydraulic fluid is contaminated?

If the hydraulic fluid is contaminated with dirt, water, or other substances:
Reduced Efficiency: The system's efficiency can decrease as the contaminated fluid affects the flow and pressure. Pumps and valves may not operate properly, leading to sluggish performance.
Component Damage: Contaminants can cause wear and tear on pumps, valves, and cylinders. Metal particles in the fluid, for example, can scratch the surfaces, leading to leaks and premature failure of components.
Overheating: Contaminated fluid can cause the system to overheat as it disrupts the normal heat transfer and lubrication properties of the fluid.
7.What is the most important component in a hydraulic system?

All components are crucial, but the pump is often considered a key component. It provides the energy to pressurize the fluid. Without a properly functioning pump, the system would not be able to operate. Valves also play an important role in controlling the flow and pressure of the fluid to the desired actuators.
