Main functions
This series machines are mainly designed for tension, compression, bending and cutting test of metal materials and meet with the requirements of GB/T228-2002”Metallic materials-Tensile testing at room temperature”. This machine is also used for compression and bending test of nonmetal materials, such as cement, concrete and so on. Equipping with special auxiliaries, it can be used for mechanical property testing of fastener, wire rope and components. They are ideal testing instrument for project quality testing section, university and college, research institution and industrial and mining enterprise.
Product features
1. This machine adopts oil cylinder overhead (underneath) type structure, hydraulic load, hydraulic or manually clamping specimen.
2. The main machine is separated with ergo meter, connected by high-pressure oil pipe and wire,avoiding the influence of ergo meter degree when the specimen is breaking, which makes the value accurate.
3. Testing force indicator dial adopts closed type, which makes scale clear.
4. Loading speed indicator makes operation more convenient. It has three kinds speed: 0.4 rotor/min, 0.8rotor/min and 2rotor/min.
5. Automatic tracer is installed upright of ergo meter shell and can magnify the straining original shape by 2 or 4 times according to the requirements of test.

Q: Why does the electric contact pressure meter sometimes stop when the contact reaches the upper limit of the pointer?: The upper contact is not in contact with the pointer contact. Set the upper and lower electric contact pressure gauge, pressure rise, pressure gauge pointer moving upward, moving the pointer and limit contact with the pointer beyond the limit point will be disconnected, and the upper limit is reached the limit set. Because the hydraulic station valve generally has different degrees of leakage, the pressure will gradually decrease, the pointer dropped to the lower limit, it will give the letter power and then step up.

Q: What is that in front of the pneumatic valve? There is a pressure gauge, an air tank, and a knob: What you are talking about is a pneumatic filter with filter pressure reducing valve, filter and pressure reducing valve. The function of the filter is to filter and adjust the pressure. "SMC pneumatic service network" technical articles, detailed knowledge of pneumatics.PS. filter pressure reducing valve under the glass (or metal cup) is not gas tank, knob is used for regulating pressure.

Q: The pressure gauge is red, yellow and green to indicate the pressure. When the needle points to the green area, what does it mean?: It means normal pressure, yellow means high pressure, red means low pressure and can't be used.

Q: I just bought the pressure gauge. I don't want to look at it. Please tell me which expert to take a look at it. My car says front wheel 210kpa rear wheel 240kpa!!! We look at this table, where is the 210kpa ah, I'm afraid the wrong wrong, ha ha, help!! On the left is the watch just bought, and the right one with the watch on the compressor Are these two units the same?: Look at the outer ring. The numbers are blackThe 1 bar is 100KPAThen 210kpa should be in the 2.1 position240kpa should be in that 2.4bar positionOK, explain that

Q: Set up a factory. May I ask what equipment you need to build a pressure gauge factory?: Is the professional calibration equipment, you Baidu will know, I am Nanjing Wanda instrument factory. Hope to help you.

Q: What's the basis for the inspection of the safety accessories (safety valve and pressure gauge) of the simple pressure vessel?: I also encountered this problem, online search an article of the following content, should be able to answer your questions. Simple pressure vessel safety valve inspection cycle, in January 22, 2007, the State Administration of quality supervision promulgated the "simple Pressure Vessel Safety Technology Supervision Regulations" (TSG R0003-2007), since July 1, 2007. Article forty-third of this regulation states that the unit is responsible for the safety management of the simple pressure vessel. A simple pressure vessel that meets the requirements of this procedure does not require registration. A simple pressure vessel within the recommended service life shall not be subject to periodic inspection in accordance with the periodic inspection rules for pressure vessels. At the same time, clause fourth (four) of this code states that safety accessories such as safety valves, bursting discs, pressure gauges, water level gauges, temperature measuring instruments and other safety accessories are also applicable. It can be concluded that simple pressure vessels manufactured after July 1, 2007, the safety valve is not required to regularly check. When the simple pressure vessels to use life, such as the need for continued use, you should be in accordance with the regulations of article forty-fifth, on the basis of "Pressure Vessels Periodical Inspection Regulation" (TSG R7001-2004) to check the safety valve in the provisions for regular inspection.

Q: What kind of pressure gauges do you need for repairing refrigerators?: Maintenance of refrigerator needs with a minimum of 3 pressure gauge, 2 pieces of 2.4 kg, a 1.5 meter, pressure for a 6 tube 20-30 cm for the table header and good expansion valve, bell, head table valve is connected with the need to use teflon tape, tied to the wire head on and valve connection table header all together, even after looking for a 8 to 6 of the copper pipe welding, a set of tools to complete, maintenance of refrigerators need tools to cut, expander, welding, solder, sealing device, electronic scales, pressure gauge, fluoride bottles, evacuation tools, it is best to prepare some brass 6 and 8.

Q: What are the common measuring ranges of pressure gauges?: Common is mainly from 0~60Mpa, mainly divided into four measuring range: 0.04~0.6Mpa, 0.1~6Mpa, 1~25Mpa,, 1~60Mpa, in which 1~25Mpa is relatively small, and the other two measuring ranges are more common

Q: Is the ordinary pressure gauge oil resistant and vacuum resistant?: The use of pressure gauges should be chosen according to the specific working conditions.

Q: What is the actual size of the pressure gauge nozzle G1/2?: G1/2 pipe actual size is: pipe diameter 15mm, outside diameter 21.3mm.G is 55 degrees (non thread sealing pipe thread), belonging to whitworth thread. 1/2 marker refers to the inside diameter of the tube, the unit is inches. Insiders usually used to call thread size, an inch is equal to 8, 1/2 is 4 inches.Specific parameters:The size of code: 1/2The number of teeth per inch: 14 (i.e. pitch 1.814mm)Major diameter: 20.955mmMedian diameter: 19.793mmPath: 18.631mmNational standards are available on GB/T7307-2001.
