Electro-hydraulic pressure comprssion testing machine

The YA series electro-hydraulic pressure testing machine is mainly used for the mechanical properties test of concrete, building components and other materials.
This machine adopts the structure of the main unit and the hydraulic system, which is compact and compact. It adopts hydraulic loading, electronic force measurement, automatic tracking and measurement with force and load rate, peak hold, automatic load calibration and other functions. The test data is automatically processed and displayed, and a random test report with test date, number, damage load, compressive strength, etc. is printed. This machine is suitable for the testing and analysis of mechanical properties of raw materials, incoming materials and finished products in colleges and universities, factories and mines, quality supervision departments, and metrological verification.
This machine fully complies with the requirements of GB/T 2611-92 and GB/T 3722-92.
• Host structure
• Host
The main machine adopts the integral frame structure, which is equipped with working cylinders, pistons, upper and lower pressure plates and the like.
The load cylinder is a key component. In order to ensure its sensitivity, low friction and pressure stability, the design adopts international advanced composite sealing technology, which is made of high-quality materials and special techniques for precision manufacturing. It is equipped with safety limit, piston position indicator and so on. .
The test space is a manual screw adjustment, and a clearance eliminating mechanism is provided between the lead screw and the nut to eliminate the amount of movement between them.
The upper pressure plate is equipped with a ball-head sub-structure for automatic self-aligning.
Hydraulic source
The hydraulic system is the power source of the whole machine and is installed on the right side of the main unit. The axial piston high pressure pump is selected and connected to the motor through the elastic coupling and placed inside the fuel tank. The oil delivery valve is a valve block that integrates throttling and overflow. When the valve is closed, the oil output from the pump overflows completely back to the tank through the valve. The test and return valve can be adjusted according to actual needs to control flow and pressure.
All parts and assembly production procedures of the factory are strictly in accordance with ISO9001 quality assurance system for quality control.
