Product Description:

The testing machine is mainly used for brick, stone, cement, concrete and other building materials, compressive strength test.

Production Summary:

300kN/10kN Full-automatic resist bending compression testing machine is mainly used for brick, stone,

cement, concrete and other building materials, compressive strength test.

Hydraulic System:

The hydraulic oil tank driven by high-pressure pump into the motor oil, flows through the unidirectional valve,

high pressure filter, pressure valve, servo valve, into the cylinder.Computer control signals to the servo valve.

Control direction and opening of the servo valve ,to control the flow into the cylinder,achieve constant test

force control.

Control System:

System including digital servo valve, high-precision sensors, controllers and software, high control precision

and reliability.Meet GB, ISO, ASTM and other standards for cement, mortar, concrete and other materials

testing requirements.

System Has The Following Functions:

Closed-loop control with force;

Can achieved constant  loading rate or constant stress loading rate;

Adopt computer for electronic measurement, automatic test;

Computer automatically calculates the results and print reports.picture 1 picture 2

Test reports can be to self-design and exported to Excel  picture 3

Safety Protection Device:

When the test force more than 3% of the maximum test force, the overload protection, oil pump motor shut down.

Q:What is the actual value of the pressure gauge mounted on the pressure vessel?
Pressure difference with atmospheric pressure.
Q:What are the diaphragm materials for the diaphragm pressure gauge?
Diaphragm pressure gauges are suitable for measuring the pressure or negative pressure of a variety of fluid media which are corrosive, non coagulated or non crystalline.The diaphragm gauge and corrosion resistance can be guaranteed by means of suitable and selected diaphragms, flanges, and gasket gaskets in contact with the measuring medium.Diaphragm material: 0Cr17Ni12Mo2 (316); Fu Jin (Cu30Ni70) Monel Hastelloy; gold; tantalum (H276C) (Ta) and fluorine plastic (F4).Gasket materials: nitrile rubber; fluorine rubber; silicone rubber and fluorine plastic.
Q:What is the difference between 380V and 220V electric contact pressure gauge?
380 of the voltage can kill people, and 280 of the voltage can make the whole body numb
Q:How big is the thread type of the y-60 pressure gauge?
This size is generally M14 * 1.5 external thread.
Q:What is the working principle of the pressure gauge?
The models are different and the working principle is different1.WTY-1 - racy liquid pressure type thermometerThe model WTY liquid pressure thermometer utilizes the thermal expansion of a liquidA temperature, capillary, and Bourdon tube for measuring temperatureThe enclosed system is filled with a temperature measuring medium - liquid, when heatedWhen the temperature changes, the pressure in the closed system is due to the liquid bodyThe product changes as a result of a change in the curvature of the spring tubeThe displacement is generated by the end, and the pointer is driven through the connecting rod and the transmission mechanismTurn on the dial and indicate the temperature to be measured. This instrumentThe utility model has linear scale, small temperature package, fast reaction speed and sensitivityHigh, direct reading and other features, almost a collection of glass rod thermometer,Bimetallic thermometers, steam and gas pressure thermometersAdvantage, when the current application of the widest range of performance of the most comprehensive kindMechanical temperature measuring instrument.
Q:What are the common measuring ranges of pressure gauges?
Common is mainly from 0~60Mpa, mainly divided into four measuring range: 0.04~0.6Mpa, 0.1~6Mpa, 1~25Mpa,, 1~60Mpa, in which 1~25Mpa is relatively small, and the other two measuring ranges are more common
Q:The pressure gauge is red, yellow and green to indicate the pressure. When the needle points to the green area, what does it mean?
The pressure of the lift extinguisher is designed according to the maximum pressure of the storage tank. Work pressure is defined as the internal balance pressure of a fire extinguisher rated and filled 20 hours after being placed in the environment for 18 hours. The situation you describe is qualified. Domestic fire extinguishers generally pressure gauges are divided into three grades, both three colors. The pointer undervoltage condition in the red zone, in the middle of the green zone generally reach fire extinguishers work pressure, and in the yellow zone that is overpressure, each fire extinguisher has its own working pressure, pressure is too low will affect the use of.
Q:Band sawing machines sometimes fail to rise, sometimes very slowly, and sometimes pressure gauges have no pressure
There is no oil in the hydraulic system
Q:How is the range of pressure gauges determined?
The maximum working pressure of the general pressure gauge is 2/3 of the range, and the 0-4Mpa is selected
Q:What is the coefficient of error for the 2.5 grade pressure meter?
The calculation formula is that: the pressure of the table - pressure of the standard table / standard meter, the pressure *100% is less than or equal to 2.5% to be qualified.
