Plastic pipe creep ratio testing machine

MTSH-2 type

Plastic pipe creep ratio testing machine

Equipment use: This machine is mainly used for the determination of the creep ratio of thermoplastic pipes. Performance characteristics: Driven by servo motor, the motor drives the cantilever up and down through the transmission mechanism to realize the test loading process. This machine adopts advanced all-digital closed-loop control system for control and measurement. It uses computer to carry out dynamic display of test process and test curve, and carries out data processing. After the test, data can be reanalyzed and edited, and the product performance reaches the international advanced level.

Multi-point calibration principle of instrument force value

Force sensor multi-point calibration principle

The calculation method of the calibration value of the i-th (i=1-3) calibration points:

The force value displayed by pressing the dynamometer to about 0.16 times of the sensor range is the force value calibrated at the first point;

Pressing the dynamometer to about 0.5 times the sensor range shows the force value as the value of the second point calibration;

The force value displayed by pressing the dynamometer to about 0.83 times the sensor range is the force value calibrated at the third point;

The calculation method of the minimum calibration value of the i-th calibration point:

The calibration minimum value of the i-th calibration point = sensor range *0.3333* (i-th calibration point -1);

The calculation method of the maximum calibration value of the i-th calibration point:

The calibration maximum value of the i-th calibration point = sensor range * 0.3333 * the i-th calibration point;

Regular inspection and maintenance

Periodic inspection

The system has a highly stable electrical load calibration function. In order to ensure the stability of this function, it is required to perform the load inspection under the actual load.

In order to ensure system stability and long-term safe operation, the user is required to regularly inspect and maintain each part of the drive.

Safety device inspection

If any safety device does not work during the inspection, please contact our company or an authorized service company.

Maintenance (lubricating oil and cleaning)

Regularly add lubricating oil to the screw to prevent oil shortage. Move the boom at medium speed (50-100mm/min) and move up/down.

Add butter with a brush. <Butter name> Butter NLGI No. 2. <fueling interval> monthly

caveat

Open the screw guard when the lead screw is refueling. The protective cover is located at the upper left, lower left, upper right, and lower right. Do not open more than two protective covers at the same time. When refueling, first remove the dirty oil on the original screw, then apply new oil, and pay attention to the fingers, hair or clothes do not turn into the machine, complete the refueling work, ensure that the screw protection cover is installed.

4, the maintenance of the test machine host

[Workbench]

The tabletop has been polished to prevent rust, wipe off dust, and add some butter.

[other shell]

Wipe the case with a soft, dry cloth or a soft cloth dampened with neutral detergent.
