Execution standards and installation precautions for WDW-50 ring stiffness testing machine，Produced and developed by Tianjin Yaxing Automatic Experimental Instrument FactoryWDW-50Ring stiffness testing machine. The testing principle of the ring stiffness tester is to determine the ring stiffness by measuring the force and deformation values of the pipe during constant speed deformation. Common seepage drainage pipes, sewage pipes, irrigation pipes, conveying pipes, mud pipes, communication protection pipes, etc. all need to undergo ring stiffness testing. The ring stiffness testing machine is widely used for determining the ring stiffness of thermoplastic pipes and fiberglass pipes with circular cross-sections, meeting the requirements ofPEAccording to the requirements of double walled corrugated pipes, wrapped pipes, and various pipe standards, it is possible to complete tests such as pipe ring stiffness, ring flexibility, flatness, bending, and weld seam tension. It has button speed regulation, digital display of test force displacement, peak holding, automatic shutdown for damage, overcurrent and overload automatic protection functions. The machine adopts computer automatic control, displays experimental data and curves in real time, and is connected to an external printer to print experimental reports. The design of the host and accessories integrates our company's advanced technology, with beautiful appearance, easy operation, stable and reliable performance. A microcomputer or controller controls the motor rotation through a speed control system, and after being decelerated by a reduction system, drives the crossbeam up and down through an imported screw pair to complete the tensile and compressive mechanical performance tests of the sample. It is pollution-free, low-noise, efficient, and has a wide speed control range. *Compliant withGB/T9647-2003The requirements of "Determination of Ring Stiffness of Thermoplastic Pipes". This machine is widely used for testing the ring stiffness and flexibility of plastic pipes, as well as determining technical indicators such as lateral loads. It is an ideal testing equipment for scientific research institutions, colleges and universities, industrial and mining enterprises, technical supervision, commercial inspection and arbitration departments.

Ring stiffness testing machine Common Faults

1The main power supply of the ring stiffness testing machine does not light up and cannot move up and down

2.Check if the power supply circuit of the testing machine is connected properly;

3.Check if the emergency stop switch is in the twisted state;

4.Check if the power supply voltage connected to the testing machine is normal;

5.Check if the fuse on the machine socket is blown, please remove the spare fuse and install it.

6.The main power supply of the ring stiffness testing machine is powered on, but the equipment cannot move up and down

7.Check if it is15S(time)In the future, the device will not be able to move because the host needs to perform a self-test when turned on, which may require15Stime;

8.Check if the upper and lower limits are in the appropriate positions and there is a certain amount of operating space;

9.Check if the power supply voltage connected to the testing machine is normal

10.Has the emergency stop button been pressed
