Overview
The DYE-2000 cement press is mainly used for compressive strength testing of building materials such as bricks, stones, cement, and concrete, and can also be used for mechanical performance testing of other materials.
Product Details
Introduction;
DYE-2000 cement press machineMainly used for compressive strength testing of building materials such as bricks, stones, cement, and concrete, and can also be used for mechanical performance testing of other materials.
The cement press adopts hydraulic loading and electronic force measurement, with functions such as load digital display, loading rate display, maximum load value maintenance, overload protection, and power-off data maintenance.
Technical Specifications:
1. Test force: 2000kN
2. Relative error of test force indication: ≤± 1%
3. Dimensions of upper and lower pressure plates: φ 225mm, φ 300mm
4. Maximum distance between upper and lower pressure plates: 320mm
5. Piston stroke: 30mm
6. Piston diameter: 250mm
7. Rated pressure of hydraulic pump: 40MPa
8. Power supply: Three phase 0.75kW
9. Dimensions: 800 × 500 × 1300mm
10. Net weight: approximately 750Kg
Scope of application:
1DYE-2000 cement press machineSuitable for testing the compressive strength of building materials such as cement and mortar.
2. This testing machine is an electric hydraulic loading device, with sensors measuring force and digital display of force values. It is a commonly used testing and inspection equipment in construction, building materials, highways, bridges and other engineering units.
Maintenance of oil source:
1. Regularly check whether there are any oil leaks at the host and oil source. If any oil leaks are found, the sealing ring or combination gasket should be replaced in a timely manner.
2. According to the usage of the machine and the expiration date of the oil, regularly replace the oil suction filter and filter element, and replace the hydraulic oil.
3. When not conducting experiments for a long time, pay attention to turning off the power supply of the host. If the machine is in standby mode, the transfer switch should be turned to the "load" position, because if the transfer switch is turned to the "fast reverse" position, the power will be reduced
magnetThe directional valve is constantly powered on, which will affect the service life of the device.
System maintenance:
1. Regularly check whether the connecting wires on the back panel of the controller are in good contact, and if they are loose, they should be tightened in a timely manner.
2. If the machine is not used for a long period of time after the experiment, turn off the controller and computer.
3. The interfaces on the controller correspond one-to-one, and plugging in the wrong interface may cause damage to the device.
4. The interface on the plug-in controller must be powered off.
Host maintenance:
1. The fixtures equipped with the machine should be coated with rust proof oil for storage.
2. Due to the frequent use of the jaws of hydraulic tensile testing machines, they are prone to wear and tear. If there is too much oxide skin, it can easily cause damage to the small piston and oil leakage. Therefore, the jaws should be cleaned regularly and kept clean (preferably)
Clean after each experiment.
3. The sliding surface between the embedded steel plate and the lining plate, as well as the dovetail groove surface on the lining plate, should be kept clean and regularly coated with a thin layer of lubricating grease.
4. Regularly check the screws in the jaw area, and tighten them promptly if any looseness is found.
5. Regularly check the transmission condition of the sprocket. If any looseness is found, please re tighten the tensioning wheel.
