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: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.
Q:Pressure gauges M20*1.5, M14*1.5 need to be equipped with DN how many valves, and pressure gauges, elbow and connector specifications, models
Yes, DN15 is OK
Q:Can the pressure meter read on the computer?
This one is ok. With a CWY series of digital watches, in a pressure source, coupled with the computer on it. Provide pressure with a pressure source, connect a digital meter to 485, and then connect to the computer. On the computer, you can read directly the pressure values for each point of the pressure. On the computer will directly generate reports, and finally print out the data directly with the computer just fine. Our shipyard is used Shaanxi Chuangwei this equipment. Very convenient! Increase of efficiency!
Q:How to use the car fuel pressure gauge?
Series connected in the oil circuit
Q:Seismic pressure gauge compared with ordinary pressure is what, what is the scope of application
Seismic pressure gauges for environment vibration, the pulse of media tolerance, and the impact of a sudden unloading, the instrument is stable and clear. Widely used in machinery, petroleum, chemical, metallurgy, mining, power and other departments to measure the pressure of copper and copper alloys without corrosive medium.Shock proof pressure meter is composed of pressure leading system (including joint, spring tube, limiting screw), gear transmission mechanism, indicator device (pointer and dial) and the shell (including watchcase, table cover, table glass etc.). Vibration proof pressure gauge shell is airtight type structure, can effectively protect the internal parts from the environmental impact and pollution invasion. Vibration proof pressure gauge filled with damping liquid in the shell (usually silicone oil or glycerin) instrument, ripple resistance to working environment and reduce the vibration of medium pressure. The ordinary pressure gauge has poor seismic performance.
Q:How about the model of seismic pressure gauge?
There is a general proof letter "N"
Q:What's the meaning of diaphragm pressure gauge YTP-100?
Refers to the dial diameter of 100
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:Diaphragm pressure gauge
The diaphragm pressure gauge is the diaphragm that represents the direct response of the elastic element to the pressure
Q:Is the pressure meter special?
The pressure gauge is used on the equipment, not the special equipment. But there is a special pressure gauge.Special pressure gauges are suitable for pressure measuring instruments in production processes of various industrial departmentsA special occasion. All parts of acid resistant pressure gauge are made of stainless steel. Has strong corrosion resistance, strong corrosion resistance is used to test the pressure of medium used in external harsh corrosive environments; widely used in petroleum, chemical, pesticides, and other enterprises, all parts of corrosion resistant high pressure gauges are all made of stainless steel material, pressure system uses a special welding process. It has excellent corrosion resistance.
