Product Description:

Steel pipe compressive test machine is mainly used for brick, stone, cement, concrete and other building materials, compressive strength test, can also be used to test the mechanical properties of other materials.

Machine Summary:

This compressive test instrument is mainly used for brick, stone, cement, concrete and other building

materials,compressive strength test, can also be used to test the mechanical properties of other materials.

Hydraulic System:

The oil tank is sucked through the filter screen and be inhaled pump oil ,through the petroleum pipeline of

oil pump transport to oil valve,When the hand wheel to send off the oil, due to the role of oil will push the

piston, the oil from the return pipe to tank,when the hand wheel to open get the oil, then the working fluid into

the fuel tank through the tubing, pressure tubing through and through oil return valve to tank.

Control System:

Electro-hydraulic compressive test instrument adopts hydraulic loading, electronic measuring, with a load of

figures, the loading rate shows that the maximum load to maintain, as well as overload protection and power

data retention and other functions.

Safety Protection Device:

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


Whole set fixtures include: a set compression platen fixture

Q:Pressure gauge model Y100-1.6KPa
Contradiction between model and rangeModel is the ordinary pressure gauge (range 0~0.1~100MPa)The measuring range is the diaphragm pressure gauge (model YE-100, range 0~1~60kPa)There are two possibilities: 1, the ordinary pressure gauge Y-100, 0-1.6MPa; 2, membrane pressure gauge YE-100 0-1.6kPa.
Q:What is the calibration cycle for the pressure gauge / thermometer / flowmeter? Is there a standard to check?
According to the standard, it is the national measurement technical standard JJF 1139-2005, "the principles and methods for determining the verification cycle of measuring instruments".In fact, as a measuring instrument, it is impossible for users to determine the inspection cycle according to their specifications.At the same time, the manufacturer has already made the product according to the specifications and determined the inspection cycle, and the cycle can meet a certain requirement.For industrial metering equipment, this cycle is generally not less than one year.So:It is usually tested once a year.If the product specification requires that the cycle be less than one year, proceed as required.If the quality of the product is reliable, it can be done once or twice a year for two times, but the exception of the pressure gauge and the strong inspection equipment is three.Equipment cycles for fire, gas, gas, alarm, etc. shall be specially determined.
Q:What's the difference between the pressure gauge and the bellows pressure gauge?
The difference between the pressure gauge and the membrane pressure gauge is as follows:A pressure gauge is a general term for all tables, including membrane pressure gauges;The bellows pressure gauge can only be used to measure gas or micro pressure, while the pressure gauge can measure a lot of media or high pressure;The accuracy level of a pressure gauge is divided into 1.6 grades and the 2.5 grades are most common.The diaphragm pressure gauge has only 2.5 accuracy.The pressure gauge pressure units can be MPa, kPa, bar, mbar, PA, kg/cm - etc..The diaphragm pressure gauge is only kPa to show.Pressure gauges are usually spring tube as the inner core, the work is relatively rough.Membrane pressure gauges are usually made of diaphragm material to make the inner core, and the workmanship is more accurate.Old Han Tel: 15610939997, do not understand questions, if solved, hope to adopt.For pressure gauges and membrane pressure gauges, they have a delicate relationship. Pressure gauges are a big kind. Bellows pressure gauges are one of them.
Q:What do you think of this air conditioner pressure gauge?
The temperature of R22 looks at the red inner ring,The pressure of the R22 value corresponding to see the outer black value (35kg/cm - =3.5MPa is 10 times),The pressure values are all on the outermost ring, regardless of the medium;There are four kinds of media in the red circle and blue circle, which are the temperature of the corresponding medium under the same pressure.
Q:What's the function of the oil pressure gauge? Where does it fit?
The role of oil filled is shockproof, so there are places where vibration can be used, but it should be noted that it has two kinds of silicone oil and glycerin, and if used for outdoor low temperature, must use silicone oil table.There are many occasions of shock, such as injection molding machines and compressors, which can be filled with oil pressure gauges
Q:Where does the meter check the pressure gauge? How long is the training time?.
Where the metering and testing center is available, they will regularly train and collect evidence. Consult your location's measuring and testing center!
Q:Can the pressure gauge be reversed installed?
Yes, the location does not affect the accuracy of the data
Q:How do I know the model of the pressure gauge?
The best consultation with manufacturers of pressure gauges, they will give you a professional answer, my home pressure gauge is Nanjing Wanda instrument factory, the use of sleep can also be, the price is not expensive
Q:What is the PSJ of the pressure gauge?
PSJ is the nominal pressure of a watch
Q:Is the pressure gauge also a pressure sensor?
A pressure meter that is converted to other signals and is called a pressure sensor. The pressure gauge is just a measuring and displaying instrument.
