What are the factors that determine the quality of a plastic tube tester?

Plastic tube testing machine of ball screw, sensor, motor, software and hardware, the transmission system is an important part of the testing machine, how to choose the high quality machine from many enterprises, the five factors plays a decisive role.

1. Ball screw.

The plastic tube tester currently USES a ball screw and a trapezoidal screw.In general, trapezoid screw clearance is large, the friction force is large, and the service life is short.At present, there will be some manufacturers in the market, in order to save costs and gain more profits, we will use trapezoid screw instead of ball screw.

2. Sensor

The sensor is an important part of the precision and stability of the testing machine. The type of the sensor of the plastic tube tester on the market is S type and spokes.The low accuracy of the internal resistance strain gauge, the anti-aging ability of the fixed strain gauge and the bad material of the sensor will affect the accuracy of the sensor.

3, electrical

The high quality plastic pipe testing machine adopts ac servo speed control system, and the panasonic ac servo motor is stable and reliable. It has the protection device of overcurrent, overpressure and overload.On the market at present there is a plastic tube test machine adopts ordinary three-phase motor or frequency conversion motor, the motor adopts analog signal control, the control response is slow, inaccurate positioning, generally narrow speed range and high speed they don't have a low speed or low speed and the high speed and speed control is not accurate.

Software and hardware.

High quality plastic pipe testing machine adopts brand computer, control system software for Windows XP operating system platform, has fast, mild interface, simple operation etc., can meet the needs of the measured results of different materials, according to national standards, international standards or industry standards measuring physical performance test of various kinds of materials.

5. Transmission system

The transmission part of the plastic tube tester is mainly two kinds, one is the circular arc synchronous gear belt, the precision screw side transmission;Second, ordinary belt transmission.The first type of transmission is stable, low noise, high transmission efficiency, high precision and long service life.The second type of transmission does not guarantee the synchronization of the transmission, so the accuracy and stationarity are not as good as the first transmission system.
