Main functions :

 YES series digital display hydraulic compression testing machine are mainly used for test the compression resistant strength test for building materials, such as brick, cement, concrete specimen and component, etc. Equipped with specials auxiliaries, it can be used for bending resistant test of building materials and compression resistant test of red bricks. They are perfect testing instrument for building project detection department, quality testing section, university and college, research institution and industrial and mining enterprise.


Product features:
1.Host machine is distyle type, which makes the conformation compact and arrangement reasonable.
2.Manually controlling compression load is easy and convenient.  
3.Mechanic limit pistons protection assures the safety of testing.
4.Setup overload  protection which can stop automatically,when the load exceeds the maximum by 2-5%.
5.Data acquisition system adopts advanced CMOS chip integrated technology, real time displays force and force peak value. So the machine is accurate and stable.
6.Display loading rates, so the manual load is more homogeneous and accurate.
7.Reserved data interface can connect with network directly, realizing resource sharing.

Q:Construction drawings marked life water supply, fire water supply test pressure value of 0.6 and 1.4, respectively, what kind of pressure meter should I choose?
Nominal diameter of pressure gauge (mm) 40; 60Select accuracy level 2.5; 4Nominal diameter of pressure gauge shell 100Select accuracy level 1.6; 2.5Nominal diameter of pressure gauge shell 150; 200; 250Select accuracy level 1; 1.6The accuracy of the pressure gauge is not pressure,??? Speechless
Q:Where is the safety valve and pressure gauge for the gas tank?
Units with inspection qualification can be identified.
Q:The role of a pressure gauge
Its function should be to indicate the internal pressure of the pressure vessel (boiler, pipe, etc.)
Q:How to check the fire valve pressure gauge as normal?
The pointer is normal in the green area!
Q:How does the air conditioning pressure gauge add readings?
The lower right corner, 2.5 below, has a "Mpa", which indicates the inner ring black. The number of units is "Mpa", that is, "MPa", the pointer pointing to 0.5, read as 0.5 MPa, and if it points to 2, then read as 2 mpa. 0.5 MPa, =5 pressure, 2 MPa, =20 pressure.
Q:If the pressure gauge of the fire extinguisher is damaged and the interface of the pressure gauge is broken, will the fire extinguisher leak?
The pressure gauge of the extinguisher won't leak.Domestic fire extinguishers generally pressure gauges are divided into three grades, both three colors.1, when the pressure gauge pointer refers to the red part, indicating that the pressure in the bottle is not enough, the fire extinguisher can not be used properly.2, refers to the yellow part, indicating that the pressure is too large, prone to danger.3, when you refer to the green part, it shows that the fire extinguisher is normal.
Q:What kind of valve does the pressure gauge valve belong to?
Pressure gauge valve is a special valve, from the valve structure, belonging to the needle valve.
Q:Our unit has a 2.2kW water supply motor, running with EV1000. How to control according to the remote pressure gauge? Is to control the pressure within a certain range. Read the instructions, there is a process closed loop control parameters, but not quite understand.. please expert advice. It's best to say what parameters you need to change.Added 15 points to answer satisfaction.
Method for controlling water pump by remote pressure gauge by Emerson frequency converter:The remote contact signal is first transmitted into the PLC, and after the arrangement, the starting signal of the frequency converter is uniformly sent through the PLC. PLC can judge or delay method to control the frequency converter start and stop pump action, to achieve not only switch control water pump, but also soft soft stop pump effect. As for the wiring, relatively simple, PLC contact is connected to the frequency converter to start, stop contact. Of course, the water pump protection circuit is completed. Logical control is done by PLC.Note: it is not suitable to control the frequency converter directly with the contacts of the remote pressure gauge. First of all, the contact jitter, will damage the inverter, and secondly, the number of contacts is not enough.
Q:Why should the pressure gauge be checked regularly?
As the pressure gauge is used for a period of time, the internal parts are subjected to wear and deformation, which results in various failures or variations in the magnitude of the instrument, resulting in loss of accuracy and over tolerance. In order to ensure the accuracy of the pressure meter value, in order to achieve the correct indication, safe and reliable operation of the purpose, the pressure gauges should be periodically tested.
Q:Where is the pressure gauge checked?
The local quality and Technical Supervision Bureau's Institute of measurement and measurement.
