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:11 kw frequency conversion, plus an electric contact pressure meter to control a water pump motor. It requires low 4 pressure, high point and 8 pressure. How can I connect it?. Manufacturers to the approach of water pump to low-end wine began to maintain pressure, but not rising in opposition, the motor does not stop, what is the reason?. Also, I bought the electric contact pressure meter, there are 4 terminals, red at the bottom of the electrical contact, green in the middle, yellow in the above, the producer said I received the wrong end of the public, but I have three lines have been inverted. The motor is not automatic stop, master pointing what happened: 1, since there are four terminals, it must have two is the power and ground, the other two are respectively corresponding with the output of high pressure and low pressure, general public is of course, so please make sure the power and ground, determined after measuring current and which is communicated with the. For less than 4 indicating pressure, another is the 8 high pressure, this is my guess, please implement this situation with the manufacturers.2, if you use a universal inverter, then when less than 4 pressure points, the inverter has to start the signal, until the 8 pressure point to arrive, you must slow down the frequency converter parking. At this point the pressure will gradually decrease and start the inverter when less than 4. Visible, below the 4 pressure point, the inverter must start, 8 down to the 4 stage, the inverter does not run until the pressure is less than 4, then trigger the start frequency converter3, frequency converter (non trigger level, the inverter has the function), 4 pressure points and start command series, 8 pressure points and stop command series, starting terminal and multi function terminal respectively contact transducer (multi function terminal need programming, three line mode, the brand names are

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:How to control three-phase motor with electric contact pressure gauge: Electric contact pressure gauge contact capacity is about 1A, and the pressure gauge installation position basically has vibration phenomenon, unfavorable, so pull on contact, the first thing to consider is the pressure gauge and the measured pipe connected by a hose, pressure gauge and pressure gauge with fixed contacts to control the intermediate relay coil, often open contact of the intermediate relay to control the AC contactor coil, AC contactor main contact with motor.

Q:Working principle of electric contact pressure gauge: The work principle is very simpleIt uses sliding resistors to control the switchThe current signal is outgoing

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: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:Is the pressure meter special?: No, the pressure gauge is instrument, and many special equipments are equipped with pressure gauge.

Q:What kind of oil is it in the oil filled pressure gauge?: Don't talk nonsense! What you said is the general vibration proof pressure gauge, silicone oil filling. Other oils do not work

Q:How do you contact the pressure meter to the pump control box?: The yellow line is connected to the power of L, the red line is the high stop contacts connected in series AC contactor start coil circuit (intermediate relay normally closed contact), the black line is low start contacts, and the intermediate relay normally open contacts.

Q:What does the pressure gauge "Y100 0~60MPa" mean?: Y100 refers to the pressure gauge the diameter is 100mm, 0~60MPa refers to the measurement range of the gauge is 60MPa. with hydraulic Meari
