Valve Testing/ Testing Benches

The testing stand is equipped with modern amenities like PLC control, manual override, SCADA for result display, result storage and retrieval for better optimising the testing process. It can also be manufactured with a wide range of attachments, that are more suited to your end application.  

(Component performance is determined by comparing test results of the component loaded with a manufacturer’s specifications to an unloaded condition) 

Hydraulic cylinders:

 The main cause for failure in a hydraulic cylinder is the leakage in the cylinder, may be internal or external. This can be tested by subjecting the cylinder to operation and determining the leakage during piston travel. Both single acting cylinders and double acting cylinders can be tested for faults and depending on the type of cylinder selected, the leakage can be detected on stroke. There are also some other defects that can be detected in cylinders like cracked cylinder walls or faulty packing. 

Hydraulic Pumps

The main cause for failure in pumps is external leakage or volumetric efficiency. They are tested at various speeds from 100 rpm to 2200rpm. The testing stands consists of an universal mounting mechanism and varying speed and torque ranges to determine the dynamic operating efficiency of the pump. The power and speed control of the test stand is done by an open loop hydraulic system.The readings are compared with the original manufacturer’s specifications to determine the quality control of the equipment and determine the efficiency of the pump under dynamic conditions. 

Motor:

The testing for the motor is much similar to the testing of a hydraulic pump as it is dynamically tested by loading it on a universal mounting system operated under varying speeds and torque ranges by the drive shaft. The power and speed control of the stand is done by an open loop hydraulic system. The readings of the test are compared with the original manufacturers specifications to determine the efficiency of the motor under dynamic conditions. 

Valves:

The test conditions for a valve are simple and less time consuming. The parameters like  pressure and volume can be pre-determined and failures like external leakage or pressure drop can be obtained. This data can then be compared with the original manufacturers data to determine the overall efficiency of the valve. We can also customise the testing stand to work under conditions where the valve is either gear operated or automated with the actuator assembly.
