Ⅰ、Main functions:

WDW series are suitable for tensile, compression, bending ,cutting, shearing and tearing test of rubber, plastic, electrical wire and cable, composite, plastic profiled bar, waterproof roll, etc. They may add test methods or rules according to customers’requirement .They are essential testing instrument for quality testing section, university and college, research institution and industrial and mining enterprise.

Ⅱ、Product features:

1,This machine equips alternating servo motor for driving crosshead and imported photoelectric encoder for displacement measure.

2,This machine is accompany with the digital multi-channel closed loop control system which applicates the latest monitoring and control systems with lots of advanced professional and technical development. ,

3,Control software can automatically finger out routine data, such as tensile modulus of elasticity, extend rate after rupture, non-proportional extend strength RP0.2, etc.

4,It can realize three closed loops control and real time display many testing curves of force-displacement, force-time, and stress-strain. These curves automatically switch. Testing process control and data processing conform to the requirements of GB.

5,This machine has the following performances: Auto zero, auto gear shifting or no subsection, auto indication, auto save, unicontrol or multistep programmed control, auto stop, auto analysis or assistant manual analysis, batch test, testing result statistic, curve select and over load protection. And the machine is beautiful, multifunctional, and operates easily and reliably.

Q: What does the condensing pressure gauge in the refrigeration system measure?: Measure the pressure of the condenser to detail

Q: Cutting acetylene bottles on how there are 2 pressure gauges, which is an adjustable, adjustable number, and oxygen. Thank you!: There are two pressure gauges on the acetylene meter. One is a high pressure meter that measures the pressure in the bottle (i. e. the amount of acetylene in the bottle). Another piece of table is a low table, can be adjusted, which is cutting the required pressure, the pressure is related to the thickness of the plate according to the number ofAn oxygen meter is the same as an acetylene meter

Q: What is a negative pressure gauge?: The negative pressure gauge should be another name for the vacuum meterVacuum meter: Instrument Based on atmospheric pressure for measuring less than atmospheric pressure.

Q: The outlet flow of centrifugal pump to adjust the valve closed small, vacuum gauge and pressure gauge change?: The flow rate decreases, the loss is small, the vacuum of vacuum table decreases, the head increases, and the pressure of outlet pressure gauge increases

Q: Why is the manifold pressure gauge called the manifold pressure gauge, not the air conditioning pressure gauge group?: The manifold pressure gauge is called the manifold pressure meter, which means it can measure the pressure of a plurality of pipes, and the manifold is the meaning of the manifold;Turn left and turn right |Manifold pressure gauge structure as shown, mainly by the high pressure meter, low pressure table, high pressure manual valve, low pressure manual valve, valve body and 3 hose joints. High and low pressure meters are used to detect the pressure at the high and low side of the refrigeration system. Low pressure side pressure gauge is used to display the pressure, are also used to show the degree of vacuum, vacuum pressure reading range is 0~0.101MPa, graduated from the beginning of 0, shock process is not less than 0.42MPa; the pressure range of pressure meter to measure the high side from the beginning of 0, the range of not less than 0.211MPa.

Q: How does the air conditioning pressure gauge add readings?: The lower right corner, 2.5 below, has a "Mpa", which indicates the inner ring black. The number of units is "Mpa", that is, "MPa", the pointer pointing to 0.5, read as 0.5 MPa, and if it points to 2, then read as 2 mpa. 0.5 MPa, =5 pressure, 2 MPa, =20 pressure.

Q: Why does the internal surface of the pressure gauge contain oil?: The utility model has the function of shock proof, and the pressure gauge with silicon oil is a shockproof pressure gauge.

Q: Does the pressure meter belong to the field of mechanics?: The pressure gauge shall be attached to the measuring instruments. The question itself is not clear. Maybe you can answer that:1) the result of the pressure gauge test is pressure, which of course belongs to the basic quantity of mechanical research;2) no matter what type of pressure gauge, its working principle requires the knowledge of mechanics to explain clearly;3) the principles of the common pressure gauges (including vacuum meters) are usually described in the course of fluid mechanics or related mechanics.

Q: The hydraulic machine of the electric contact pressure gauge old bad, an oil spill, and two pointer does not return, I personally think that is the quality of table or hydraulic diaphragm was too frequent starting impact times too much damage, used in hydraulic machine is not reliable electric contact pressure gauge. Present your valuable comments or suggestions, and Solutions: The hydraulic machine out of pressure is not too stable, this causes the pressure gauge frequently in that swing, and the electric contact pressure gauge used in pressure fluctuation environment is little use to play its normal life
