As name implies, a compression testing machine is very unique hand operated equipment used for compression tests. Manufacturers who deal in the compression testing machine domain offer a wide range of computerized compression testing machines for use of testing. Technically, a compression testing machine is made with concrete specimens up to 20cm diameter and 30 cm in height. In several regions like India, UK & America, these machines are used by the industries for standard testing. The machine contains a hydraulic jack fixed to its base and the upper platen is equipped with screw for self-aligning action. The screw passes through the cross head and can be raised to some inclined angles as requirement arises.
The machine enables a way to lower the initial clearance adjustment. The lower platen of the machine rests on the jack ram and a catering pin is used to position it. The loading in the compression testing machines is done by the inward movement of the lower platen available in the machine. Pumping unit is another important part of the machine is an automated pumping unit wrapped in an elegant console. This pumping unit is connected with a steel connecting tube with a junction box is suitably fixed to a push button starter.
The machine contains a pointer that helps to take up the comprehensive reading if specimen fails to extend result in right manner possible. In industrial setups, compression testing machines are fitted with a hand wheel control that further intensifies application load rate. An electric pumping is also available with the compression testing machines that are used to off the motor automatically on the prescribed load limit. Some machines even incorporate the pumping unit that push constant power supply to the machines in the case of sudden break-down. The motor stops in case and doesn’t start unless switch is operated.
The machine is best for the channel construction and offers a great bend for excellent rigidity. The hydraulic jack available in the machines is precision machined and a piston and cylinder duo to used ton confers fine tolerances. The lower platen of the machine is located on the base, and equipped with concentric grooves for centering the specimen easily and comfortably. The upper platen is usually mounted on a swivel arrangement of the machine for self aligning action to execute the function thoroughly.
