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.
Fixture:
Whole set fixtures include: a set compression platen fixture

- Q:Measurement data, installed in the normal position, do not know whether to reverse installation, please professionals to help answer! Thank you Urgently!
- Yes, the location does not affect the accuracy of the data
- Q:How does the fire pump pressure meter work?
- Imagine a floor of 3 meters, the 27 floor is 81 meters, so at least 81 meters to provide water pump pressure + atmospheric pressure, converted to 9.8*81*1000pa+1.01*100000pa=0.8938Mpa
- Q:How does the air conditioning pressure gauge add readings?
- First of all, air conditioning and fluorine are professionals do, not professional, do not self filling.Air conditioning refrigeration when filling, the most outer ring two digit number is the internal pressure of the air conditioner. (10 stands for 10 pressures, 20 stands for 20 pressures, and then by analogy)Different air conditioner models require different pressure, large frequency converter pressure and low fixed frequency machine pressure.Fluorine can not only look at the pressure, but also with refrigerant filling amount of comprehensive assessment.
- Q:How to check the fire valve pressure gauge as normal?
- Building regulations: hydrant mouth pressure should not be greater than 0.8MPa; the water pressure is not greater than 0.5MPa; the "high regulation": the building height of not more than 100 meters, the most unfavorable pressure should not be less than 0.07MPa; more than 100 meters should not be less than 0.15MPa; the water gun full water column general building should not be less than 7 meters, a and B class of workshop, more than 4 layers of workshop and warehouse, and high-rise building multi-storey buildings and buildings more than 6 storeys height of not more than 100 meters should not be less than 10 meters, high-rise buildings should not be less than 13 metres.Spray system is: the worst point of the system, the work pressure should not be less than 0.05MPaSome people love to see the fire pump room pressure, the pressure must be large, the requirements are not less than those of numerical pressure above the highest point on the line, a building with a fire hydrant with a pressure gauge, you see that the pressure gauge on the line. Spray, you go to the top end of the test water pressure gauge on the line.
- Q:Does the pressure meter belong to the field of mechanics?
- Classical mechanicsTwo basic assumptions: one is that the time and space is absolute, regardless of length and time interval measurement and motion of the observer, the interaction of transfer material is the instantaneous arrival, two of all physical quantities can be observed, in principle, can be measured with infinite precision.
- Q:Ytn10 and yn10 have these two types of pressure gauges? What do these two models stand for?
- YN and YTN represent proof pressure gauge is just not the same manufacturer mark.Y stands for pressure gaugesT stands for spring tube structureN shockAlso, there is no YN10 and YTN10, only YN100 and YTN100
- 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:What are the precision grades of precision pressure gauges in our country?
- According to the JJG49-1999 spring tube precision pressure gauge and vacuum meter verification regulation, the accuracy degree of the pointer precision pressure gauge is:0.6, 0.4, 0.25, 0.1, 0.06
- Q:Mainly inside these two laps, freon temperature is what, oh, do not understand, usually the original table, I see the MPa, this is not, thank you!
- Black is the pressure gauge, per kilogram / square centimeter, approximately equal to 100 kPa, so it consists of two scales. The pink one is too small to see clearly.
- Q:See others welding, found that there are two pressure gauges on the cylinder, one is 0-0.3 range as if, and the other is 0-4 range, ask why, is it safety considerations or other reasons? thank
- 0-0.3MP is a low pressure meter, which is an oxygen pressure reducer. It converts the high-pressure oxygen into a uniform low-pressure oxygen through the knob handle to supply welding or cutting. 0.3MP's pressure is very common.0- 4MP is a high pressure oxygen meter. The oxygen bottle allows 15MP gas to be filled. This is the gas left in the cylinder at present, 4MP. High pressure makes gas cylinders fill more gas.
