Ⅰ、Main functions
This series are used for compressive strength test of building materials, such as the specimen and component of cement, concrete and so on. Equipped with special auxiliaries, it can be used for bending resistant test of building materials and compression resistant test of red bricks. We can evaluate result parameters stated in related standards. They are perfect testing instrument for building project detection department, quality testing section, universities and colleges, research institution and industrial and mining enterprise.
Ⅱ、Product features
1、Host machine is with double column type, which make the conformation compact and arrangement reasonable.
2、Adopt precise electro-hydraulic servo proportional valve. The speed is fast and the controlling accuracy is high.
3、Mechanic limit pistons protection assures the safety of testing.
4、Setup overload protection which acn stop automatically,when
the load exceeds the maximum by 2-5%.
Ⅲ、Controlling system
This machine is with digital and multi-channel loop of measuring and controlling system. It adopts force closed loop control technique and has the function of constant stress loading and load keeping. Loading speed can be arbitrarily set and the testing curves can be real time displayed.
Characteristics of software：
1、The software integrate bending resistant test and compression resistant test procedure , such as bricks, cement, concrete and mortar.
2、The software divide testing procedure as follows: tile compression resistant executive program(GB13544—2000), cement compression resistant testing program (GB17671—1999), concrete specimen testing program(GB/T5001—2002)and mortar testing program(GB170—90).
3、There is no subsection in all process. (Or classify according to the requirements of customers.)
4、Complete test in batch automatically and adjust breaking of specimen.
5、Windows Style can be controlled by human or computer.It is easy to manage and control,collect and calculate.
6、Record and save testing datas automatically.

- Q:What does "MPa" on the pressure gauge mean?
- How many MPa does it mean?
- Q:The hydraulic machine of the electric contact pressure gauge old bad, an oil spill, and two pointer does not return, I personally think that is the quality of table or hydraulic diaphragm was too frequent starting impact times too much damage, used in hydraulic machine is not reliable electric contact pressure gauge. Present your valuable comments or suggestions, and Solutions
- The hydraulic machine out of pressure is not too stable, this causes the pressure gauge frequently in that swing, and the electric contact pressure gauge used in pressure fluctuation environment is little use to play its normal life
- Q:What is the pressure gauge cock
- It's the pressure gauge valve
- Q:What is the maximum allowable error of a precision pressure gauge of 0.4? How to calculate?
- Maximum allowable error = + (range *0.4%)You can't tell the method of calculation only if you don't know the scale of your watch.
- Q:The water remote pressure gauge hands swing frequently do?
- 1, pointer rotation slow or jitterReason:1, the transmission parts of the clearance is too small, the transmission is not flexible, increase the gap, or add a little Watch Oil2, moving parts between the active parts of fouling, transmission is not working, cleaning, rust removal, in addition to dirt or replacement transmission3, the free end and connecting rod connection is not flexible, adjust the connection mode until flexible4, the pointer with the dial, table cover friction, correct the pointer, thicken the glass lining below2, the needle rotation is not smoothReason:1 、 the sector gear tilts to correct or replace the gear2, the needle axis bending, straightening needle axis3, plywood bending, correcting the flatness of plywood4, the pillar tilts, causes the upper and lower plywood not to parallel, correct the strut, the addition and subtraction washer, causes the splint parallel3, pointer jitter bigReason:1, measured medium pressure fluctuations, close the valve opening2, the gear is not good, adjust the gear with the state3, the needle sleeve and shaft coordination is not good, adjust repair pointer sleeve and shaft clearance gap
- Q:What kind of oil is it in the oil filled pressure gauge?
- Pressure meter which is filled with glycerin or silicone oil, and other can not, the general manufacturers are full of glycerol, because glycerol is cheaper, but the temperature of glycerol is relatively large, good point is filled with silicone oil.
- Q:I am doing water treatment works, water pump is connected with the back of my mechanical filter, know the maximum pressure pump working for 2.5MPa, so I want to be in place to install a water pump outlet pressure gauge, pressure gauge pressure range is how much?
- I'm a pressure gauge. Let me tell you. I hope I can help you
- Q:The structure and working principle of the membrane box of the membrane pressure gauge?
- The film box can not be fixed in the case, usually at the center of one of the diaphragm opening, as the inlet and fixed, then another diaphragm center is free end
- Q:Fire hydrant pump, spray pump, starting pump, pressure gauge and spray pump, pressure switch is how to wiring?
- The pressure gauge doesn't seem to be connected.It is a pressure switch switch, the 24V is introduced into the pressure switch, and then come out from the other end, connected to the 24V relay 13 feet, the negative 24V connected to the 24V relay 14 feet (13, 14, and then put on) a pair of normal relay contact is connected with the pump start line can be strong.
- Q:Will the air compressor inspection (pressure gauge, safety valve, gas tank) is where to go to detect, how much is the approximate cost?
- The safety valves go to the local Quality Supervision Bureau at the municipal level, and they will designate a place for you to check.Pressure gauge local measuring instruments inspection qualification institutions, general provincial and municipal metering Inspection Institute on the line.
