How much does it cost to supply an electro-hydraulic pressure testing machine

1main purpose

200 ton electro-hydraulic pressure testing machineUsed to measure the compressive strength of building materials such as bricks, stones, and concrete.

This machine is used for electric hydraulic loading, sensor force measurement, digital display of force values, printer printing of force value data, and conversion of compressive strength. This testing machine complies with the national standard "Standard for Test Methods of Mechanical Properties of Ordinary Concrete", and should manually control the loading speed. It also has a loading speed indicator device, peak holding, and overload protection functions. It is a testing and inspection equipment for construction, building materials, highway bridges, and other engineering units.

3、 Structure Introduction

200 ton electro-hydraulic pressure testing machineIt consists of three parts: the main organism, hydraulic control box, and force measuring instrument.

1body part

The testing machine body is connected to the cylinder body and upper beam by four columns

There is an adjusting screw installed on the upper crossbeam of the testing machine. The large hand wheel and nut screw can adjust the no-load height of the testing machine. The lower end of the screw is equipped with a ball seat and an upper pressure plate. The lower pressure plate is placed on the piston of the oil cylinder. When the specimen comes into contact with the upper pressure plate, the upper pressure plate seat can self adjust and balance, keeping the specimen horizontal with the upper and lower pressure plates. The lower pressure plate is engraved with a marking line for locating the test piece. When conducting the test, the test piece should be aligned with the marking line. A dust cover is installed under the lower pressure plate to prevent or reduce dust from entering the oil cylinder and damaging the cylinder body or oil seal during piston lifting. There is a sealing device between the piston and the oil cylinder to prevent oil leakage. However, when there is still a trace of oil leakage from the piston during use, there is a circular oil groove at the top of the cylinder body and a drainage channel to discharge it back to the large oil tank.

2Hydraulic control part

The control box of this testing machine mainly consists of an oil tank, an oil pump, an oil filter, an electric motor, a speed valve, a return valve, etc. The oil pump is a direct rotating axial five column pump. When the testing machine is loaded, the loading speed valve should be manually controlled to restore the control of the piston rising speed (which is integrated with the safety valve). When unloading, the return valve can be rotated, and the oil cylinder will slowly descend. The testing machine has already adjusted the safety valve to the appropriate position at the factory, and users cannot adjust the safety valve during normal use.
