Type electro-hydraulic pressure testing machine concrete press press testing machine wholesale price
[Detailed description] The concrete pressure testing machine complies with the test procedures of B "Standard for Testing Methods of Mechanical Properties of Ordinary Concrete" and is the most independently developed and produced Advanced compression testing equipment, this machine is easy to operate and is a must-have equipment for the construction, highway, and building materials industries.
The concrete pressure testing machine adopts hydraulic loading, and the electronic force measurement has functions such as digital display of test force and loading speed, and maximum test force maintenance. The machine can also be equipped with a computer, which can display the loading curve, perform data acquisition and processing, and can also directly print and store the experimental results.

2. Installation and debugging
, Pressure testing machine installation
The pressure testing machine should be installed in a clean, dry, uniform temperature, no vibration around the house, and no corrosive gas influence. The installation foundation should be solid and reliable, and the anchor screws should be aligned with the base.
After the pressure testing machine is adjusted to a horizontal installation, use clean cotton gauze soaked in kerosene to wipe off the anti-rust agent on the machined surface, then wipe the surface clean and apply a thin layer of mechanical oil.
, Pressure testing machine debugging
This debugging content only includes preparation work before operation. For other content, please see the Precautions section.
Oil filling of the pressure testing machine
Open the rear door, lift the fuel tank cover and inject an appropriate amount of mechanical oil into the fuel tank to the oil mark. Due to changes in temperature, the oil used is slightly different. The oil specifications are described as follows:
When the ambient temperature is ℃, B mechanical oil is used.
When the ambient temperature is ℃, use B mechanical oil.
Electrical connection of the pressure testing machine: Plug the random power plug into the corresponding socket. The power supply is.
Start the oil pump to exhaust the pressure testing machine: open the oil return valve and the oil delivery valve. Turn the power switch (on the back of the control box) to turn on the power of the pressure testing machine. The test screen will be displayed after a few seconds. Press the start button, start the motor, and the oil pump starts to work. After continuing to work for about one minute, close the oil return valve. At this time, you can find that the lower pressure plate rises slowly. After the lower pressure plate rises for a certain distance, close the oil delivery valve and open the oil return valve. The pressure plate is now in a lowered state. Repeat the above steps ~ times to completely eliminate the gas in the system. If it still cannot be eliminated, you can exhaust it as follows: After stopping the machine, open the front door, use the wrench that comes with it to unscrew the large nut on the front face of the oil pump, then turn the machine on to drain the oil. When the oil flows out smoothly, shut down the machine and screw on the nut. .
