Test method for rubber and plastic calender
Subject content and scope of application
This standard specifies the test conditions, instruments and methods for rubber and plastic calender. This standard applies to the inspection of rubber and plastic calenders. 2 Reference standards
HG5-1613 Test method for chilled cast iron rollers HG/T2108 Determination of sound pressure level of rubber machinery noise 3 Technical requirements inspection
3.1 Detection of calender idling power
3.1.1 Test conditions: After the calender has been idling for 1.5 hours, 3.1.2 Detection instrument: power meter.
3.1.3 Test method: At least three measurements, and the maximum value of the readings is taken. 3.2 Detection of bearing body temperature rise during idling 3.2.1 Test conditions: After the calender has been idling for 1.5 hours, 3.2.2· Detection instrument: semiconductor point thermometer (hereinafter referred to as point thermometer). HG/T2150--91
3.2.3 Detection method: Use a point thermometer to measure at least 4 points on the outer shell of each bearing body on the inner side of the left and right frames, and take the maximum reading. The temperature rise is calculated as follows:
Temperature rise = measured temperature - working environment temperature
3.3, Detection of motor power during load operation3.3.1 Detection conditions: After 1.5 hours of load operation, Detection instrument: power meter,
3.3.3 Detection method: Measure at least three times, and take the maximum reading. 3.4 Detection of bearing body return oil temperature during load operation, 3.4.1 Detection conditions After 25 hours of load operation3.4.2 Detection instrument Ordinary mercury thermometer
3.4.3 Detection method: Place the thermometer at the outlet of each bearing return oil pipeline, measure the oil temperature, and take the maximum reading. 3.5, Detection of roller working surface temperature during load operation3.5.1 Detection conditions: After 2 hours of load operation. 3.5.2 Testing instrument: bow metal thermometer. 3.5.3 Testing method: measure at least 3 positions along the width of the roll surface (the two ends and the middle of the roll surface must be measured). The temperature deviation is calculated according to the following formula:

Temperature deviation value = measured maximum temperature specified temperature deviation value - measured minimum temperature - specified temperature 3.6.1 Testing of roll whitening layer depth and working surface hardness according to H G5-1613 regulations, 3.6.2 Detection of roller working surface roughness: 3.6.2.1 Detection conditions: After the roller working surface is finely processed, 3.6.2.2 Detection instrument: surface roughness measuring instrument or surface roughness comparison sample 3.6.2.3 Detection method: Use a measuring instrument to measure the working surface of each roller or use a comparison sample for comparison 3.7 Assembly accuracy detection
3.7.1 Detection of calender frame assembly accuracy: 3.7.1.1 Detection conditions: The left and right frame crossbeams and base are assembled 3.7.1.2 Detection instrument: Measuring shaft (straightness reaches level 2 flat ruler accuracy) or flat ruler, frame level, auxiliary plate, feeler gauge.
3.7.1.3 Detection method:
Each pair of slide side Plane (as shown in Figure 1) position error detection: Use the measuring axis to detect the diagonal (see Figure 2) and parallel detection of several sections with equal distance (see Figure 3) on the measured side, and use a feeler gauge to measure the gap and take the maximum gap value; side plane
support plane
b. Position error detection of the support plane (Figure 1) of the left and right racks (Figure 4): Use the measuring axis to detect the diagonal and parallel detection of several sections on the auxiliary plate, and use a feeler gauge to measure the gap and take the maximum gap value. The gap between the auxiliary plate and the support plane is also taken as the maximum value.

HG/T2150--91
The sum of the above two maximum gaps is the position error of the two support planes of the left and right racks. Level|| tt||Measuring shaft
3.7.2 Detection of radial runout of the working surface of the calender roller relative to the journal 3.7.2.1 Detection conditions: After idling for 1.5 hours, 3.7.2.2 Detection instrument: micrometer
Auxiliary plate
3.7.2.3 Detection method: Fix the micrometer bracket on the left and right frames to detect the radial runout of the working surface at both ends of the roller, and then fix the micrometer bracket at an appropriate position between the left and right frames to detect the radial runout of the working surface of other parts of the roller, and take the maximum reading,
3.8 Safety and noise detection
3.8.1 Safety detection
3.8.1.1 Detection conditions: When the calender is idling at high speed (close to 3/4 of the maximum speed). 3.8.1.2 Testing instrument: steel tape measure or tape measure, 3.8.1.3 Testing method: record from the start of braking to the stop of roller rotation, measure the arc length of the roller working surface during this process, test at least 3 times, take the maximum value, and the test result is expressed as the ratio of arc length to the circumference of the roller working surface. 3.8.2 Noise detection
3.8.2.1 Testing conditions: when the calender is in high-speed idling operation (close to 3/4 of the maximum speed), 3.8.2.2 Testing instrument: sound level meter (type 5). 3.8.2.3 Testing method: HG/T2108 regulations, standards exchange network·state
