Which is a good fiber manhole cover pressure testing machine

Product Introduction: The manhole cover pressure testing machine is customized according to national and European standards. This machine can use full pressure and point pressure to measure the compressive strength and deformation of each point. The pressure plate on the press is connected by axial movable connection, which facilitates load holding and constant pressure testing.

1、 Main functions and features of the manhole cover pressure testing machine product

1. Adopting a high-precision hydraulic system to drive the hydraulic cylinder, it can achieve the setting of test parameters, automatic data acquisition, processing and analysis throughout the entire test process. The loading speed can be set arbitrarily within a certain range, and the loading rate, holding time, and cyclic pressurization can be controlled; Has fracture recognition capability and automatic shutdown function.

2. This testing machine is suitable for testing specimens with a bearing capacity not exceeding 600 kN

3. Comply with the national GT/T2611 "General Technical Conditions for Testing Machines" and the national metrological verification regulation JJG139 "Tensile, Pressure and Testing Machines" standards.

4. Scheme description

The host adopts a vertical frame structure, and the main structure adopts a welded structure, which has been effectively treated to ensure the rigidity of the whole machine. The hydraulic cylinder is placed on the lower crossbeam, and the piston extends to press the test piece during operation. The fixed table size (width X length) is 1050x1050mm. The pressure head is made of alloy structural steel quenched (HRC45-50) to ensure its service life. To complete the pressure detection of the manhole cover.

Hydraulic system: Hydraulic principle: The oil pump is a load adaptive inlet throttling speed control system.

The hydraulic oil in the oil tank is driven by a motor to rotate the high-pressure oil pump, generating pressure oil that enters the oil circuit. It passes through hydraulic components such as a one-way valve, a 10 μ high-pressure oil filter, and a differential pressure valve group of the testing machine. The hydraulic oil is then controlled by the oil delivery valve to enter the oil cylinder, pushing the loading cylinder to apply test force to the specimen. The pressure sensor and program control system send signals to display the force value and loading rate on the instrument, control the flow rate of the oil delivery valve, and thus control the flow rate entering the oil cylinder, achieving control of parameters such as constant velocity test force and test force maintenance. The oil tank adopts a fully enclosed structure, which can effectively prevent dust and other debris from entering the hydraulic system, thereby improving the reliability of the hydraulic system.
