Electronic universal testing machine is the product of the combination of modern electronic technology and mechanical transmission technology. It is composed of measuring system, driving system, control system and computer. The large-scale precision testing instrument, which makes full use of the respective advantages of mechanical and electrical equipment, can carry out tensile, compression, bending and other performance tests on various materials, and has the characteristics of wide measuring range, high precision, fast response and so on. Reliable and efficient. The connection of the hydraulic system is an indispensable part of the use of the electronic universal testing machine. Here we come to Lin to introduce the connection and maintenance precautions of the hydraulic system of the electronic universal testing machine. The connection methods are as follows:

1. First, remove the binding materials at all parts of the hydraulic universal tensile testing machine, and clean the inside of the oil pipe with clean kerosene, especially the thread at the connection of each oil pipe. Check whether the gasket at the joint is complete. If it is damaged, install it with a new gasket attached to the testing machine to prevent oil leakage during high pressure.

2. The staff should use a suitable wrench to connect the oil pipes. If it is a seamless copper pipe, it should be connected to the main engine, and rely on the movement of the console to adjust the spacing to connect the control console.

3. Open the iron door of the hydraulic control box, you can see the screen oil filter. When filling oil, it is injected into the oil tank through the filter. Hydraulic oil is usually used in the testing machine. In summer, hydraulic oil with higher viscosity should be used. In winter, hydraulic oil with lower viscosity is recommended.

4. The electronic universal testing machine can not work normally because of too little oil. Too much oil will cause hydraulic oil leakage from the working cylinder port. So pay attention to the oil level when refueling.

Precautions for maintenance of electronic universal testing machine

1. When repairing fine instruments and meters, if you accidentally bounce small parts, you should first judge that they can fly to the right place. Do not look east or west. Magnet scanning and field scanning are acceptable. When using logic pen and oscilloscope to detect the signal, we should pay attention not to make the probe contact two measuring pins, because the essence of this situation is to form a short circuit under the condition of power on. In order to better understand the parameters and forms of the key points in the use of universal tensile testing machine, the software development staff specially designed a set of software, which can correctly adjust the process and control the production.

2. Please pay attention not to plug all kinds of control board and plug.

3. When inspecting the internal circuit of the instrument, if the contact points of the device components and the circuit board are coated with insulating varnish, the common hand sewing needle can be welded on the probe of the multimeter when measuring the parameters of each point, so as to pierce the paint layer and directly measure each point without stripping the paint layer in a large area.

4. It is necessary to use a multimeter to measure the hysteresis of printed circuit when checking the instrument faults in wet condition, because the primary fault in this condition is the corrosion of copper foil. Because in the case of power on, plug-in and pull-out system board will have a strong induced electromotive force, when the instant return voltage is very high, it is easy to damage the response control board and plug.

5. Can carry on the multi-faceted inquiry to the data, can enable the manager to grasp the quality control development change tendency very clearly.

The above is a small series for you to share the electronic universal testing machine hydraulic system connection and maintenance precautions, hope to help you oh!
