How to Operate a Servo-Hydraulic Testing Machine

Operating a servo hydraulic testing machine is an essential skill for those in the engineering and manufacturing industries.

It is a powerful machine that performs strength, fatigue, and endurance tests on materials and components. The machine is computer-controlled and has many features that need to be understood before use. Here is a guide to help you operate a servo-hydraulic testing machine.

The first step is to prepare the sample for the test. Clean the sample to remove any impurities such as dirt, rust, or oil. Accurately measure the dimensions of the specimen and ensure that they comply with the testing standards. Install the sample between the grips of the testing machine and adjust the grips to suit the sample type. Tighten the grips to secure the specimen and make sure that there is no slippage during the test.

The next step is to set the test parameters. It is important to select the correct test type for your material. The machine has several pre-programmed test types such as fatigue, tensile strength, and compression. Choose the correct test type and input the correct parameters such as load, displacement, and frequency. These parameters should be based on the testing standard specifications.

The next step is to start the test. Engage the machine, and the test will begin. During the test, the machine will measure the load, displacement, and other parameters automatically using sensors, and the data will be displayed on the computer screen.

How Does a Servo Hydraulic System Work? - HEICO

Hydraulic energy is used as a power source for hydraulic systems. This energy comes from a combination of potential, hydrostatic, and hydrodynamic energy (Bernoulli’s equation). Here, in addition to hydrostatic energy as a function of pressure, the effects of potential energy as a function of the liquid’s weight or height and hydrodynamic energy as a […]

Hydraulic energy is used as a power source for hydraulic systems. This energy comes from a combination of potential, hydrostatic, and hydrodynamic energy (Bernoulli’s equation). Here, in addition to hydrostatic energy as a function of pressure, the effects of potential energy as a function of the liquid’s weight or height and hydrodynamic energy as a function of flow rate are minimal.  

 Therefore, the hydrostatic energy generated by the hydraulic system’s pressure effect is considered. Hydraulic power is obtained by driving a hydraulic pump by an electric motor or an internal combustion engine. For this hydraulic power to perform its intended function, it must be controlled by control elements (pressure, directional and flow control valves) and directed to the necessary elements (hydraulic cylinders or hydraulic actuators).

 Servo-hydraulic testing machine can control the pressure, flow and direction of a fluid with an incompressible fluid and uses this hydraulic energy to produce linear, circular and angular movements that are precise and controllable. Each element in the circuit is represented by a standard symbol and connected by a pipe connection.

 Several hydraulic system functions can be seen on the diagram. For large schemes, motion and control charts can be used to determine the exact timing of action sequences. If you look closely at the circuit diagram, it looks big and complicated. For this reason, servo hydraulic system circuits are easy to construct, and any circuit problems that may arise can be easily overcome with a good knowledge of the essential elements of the course.

Hydraulic pump

Devices that convert the power received by the motors that drive them into hydraulic power are called hydraulic pumps. The pumping process for all pumps is based on the same principle. Pumping is done by increasing the volume with the suction nozzle and decreasing the volume with the outlet nozzle. There are many pumps, but the most common are vane pumps, gear pumps and piston pumps.

 Vane pump

The vane pump consists of a rotor, vanes, rings and a distribution plate with inlet and outlet ports. The rotor of a vane pump moves in slots from a motor shaft to which it is attached. The rotating vanes are thrown out by centrifugal force and follow the walls of the non-rotating ring. Therefore, as the rotor rotates, the blades form a volume along the ring that gradually increases and decreases. The intake ports through the distribution panel have a shape corresponding to an increase in size, and the exhaust ports have a shape corresponding to a decrease in size.
