In a single-acting cylinder, the piston can only move in one direction. In a double-acting cylinder, pressure can be applied to both sides of the piston, enabling movement in both directions.

Every cylinder component must be precision-engineered to ensure an airtight, leak-free system that maintains the correct pressure for safe and efficient operation. The appropriate cylinder size depends on the required force, calculated using the following formula:

Force (F)=Fluid Pressure (P)×Piston Surface Area (A)\text{Force (F)} = \text{Fluid Pressure (P)} \times \text{Piston Surface Area (A)}Force (F)=Fluid Pressure (P)×Piston Surface Area (A)

At Automotive Lift Repair Orlando Hydraulics, we manufacture an extensive range of hydraulic cylinders for all industrial sectors. We maintain high stock levels of standard cylinders.

We also produce various cylinder variants with foot, flange, trunnion, clevis, or swivel bearing mountings. Our cylinders are available with minimal lead times, and for custom-built options, we can manufacture cylinders with up to 200mm bore and 2500mm stroke at our in-house facility.

Hydraulic Motors

In a hydraulic motor, fluid pressure turns a shaft to generate torque, which exits through a port on the opposite side of the motor. The three most common designs are:

• Gear Motors: Suitable for medium pressures and flows, where fluid flows between the gears to the outlet port, with pressure differentials preventing leakage.
• Vane Motors: Designed for medium pressure and high flow applications.
• Radial and Axial Piston Motors: Ideal for high flow and high-pressure scenarios.

Gerotor and Gerolor motors are also utilized in mobile and agricultural applications to generate high power at low speeds.

To ensure optimal performance from all types of hydraulic motors, consider the following factors:

• The maximum operating pressure.
• The required speed and torque to operate the equipment.
• The displacement and flow rates.
• The type and density of the hydraulic fluid.
• The maintainability of the components and availability of parts.

Automotive Lift Repair Orlando specializes in high-torque, low-speed motors, designed to deliver maximum torque at startup while maintaining shaft speed during demanding operations. 

Hydraulic Valves

Valves are essential in hydraulic systems to control the fluid’s directional flow, making it crucial to source the correct size and type. Valves come in various sizes, materials, and mounting styles to comply with different international standards.

The three main types of hydraulic valves each serve a specific function:

• Directional Control Valves: Check valves block hydraulic oil flow, while spool valves redirect it.
• Flow Control Valves: These regulate the speed of fluid flow by adjusting the opening at the valve point

Did you know that the four main fault scenarios in a hydraulic system are pump leakage, gas leakage, valve switching degradation, and oil aeration?

To prevent these issues, it’s essential to understand how hydraulic systems operate. There are five key types you should be familiar with. Keep reading to discover what a hydraulic system is and the common types it includes.

 What Is a Hydraulic System?

Automotive Lift Repair Orlando Hydraulic systems use fluids to transfer energy from a motor to an actuator. Since the fluid is essentially incompressible, the fluid path is flexible, much like an electric cable.

1. Hydraulic Pumps  

   Hydraulic system components can be powered by various sources, particularly in hydraulic pump systems. The types of pumps include gear pumps, fixed displacement piston pumps, and variable displacement piston pumps. Gear pumps are categorized as fixed displacement since they move a specific amount of fluid per rotation, while fixed displacement piston pumps move fluid with each stroke. The variable displacement piston pump is the most commonly found hydraulic pump in aircraft.

2. Hydraulic Motors and Cylinders  

   A basic Automotive Lift Repair Orlando hydraulic system includes motors and cylinders that use pressurized fluid for mechanical work. Hydraulic motors convert pressure into torque, rotation, or displacement. Hydraulic cylinders, often referred to as linear hydraulic motors or actuators, exert force in a single direction, which can be reversible.

3. Aviation Hydraulic System  

   Another type of hydraulic system is found in aviation. This system draws fluid from a reservoir and applies pressure to various components, returning the fluid to the reservoir afterward.

4. Open Center Hydraulic System  

   An open-center hydraulic system operates without pressure, though fluid is still present, indicating that the machine is idle. The fluid flows from the actuator back to the reservoir, allowing fresh fluid to reach the pump inlet. These systems utilize a directional control valve, which results in less heat generation. All open-loop hydraulic circuits use pressurized or sealed reservoirs, and conventional systems typically have large reservoirs to allow air bubbles to escape from the fluid.

5. Closed-Loop Hydraulic System  

   In a closed-loop system, the Automotive Lift Repair Orlando pump generates pressure for the fluids, creating a continuous flow between the actuator and the pump without entering the reservoir. Instead of a directional control valve, a closed-loop system employs an additional pump known as a feed pump or charge pump. A significant advantage of this system is its ability to provide precise actuation responses.

Hydraulic systems are primarily utilized in complex and fast-moving machines, enhancing safety when working with large equipment. Before engaging with hydraulic systems, refer to this guide to comprehend the various types.

Here’s a rephrased version:

At first glance, Automotive Lift Repair Orlando hydraulic motion circuits may look similar to their pneumatic counterparts. Both rely on fluid power sources, actuators, and control valves. However, hydraulic systems differ significantly from pneumatic systems, not only in the fluids used for generating motion but also in various other aspects. 

Reservoirs are among the simplest yet most essential components of a hydraulic system. They store the hydraulic fluid when the system is idle and contain extra fluid to prevent systemic issues. This surplus fluid helps accommodate volume changes during extension and retraction, temperature variations, leaks, and more. Without a reservoir of Automotive Lift Repair Orlando hydraulic fluid, these changes could lead to total system failure and increased downtime.
