Before starting the polypropylene spinning machine, should check the components for any problems, if any problems should be dealt with in order to ensure the normal operation. Just as the aircraft had a series of precision checks before it started, although the construction of a polypropylene spinning machine was not as complex as that of an aircraft, the success of its operation also depended on the prior inspection. The following note in the operation of polypropylene spinning machine is the highlight, learn together about it.

1, the transmission part of the operation should be smooth, no abnormal sound.

2, under normal working conditions, screw extruder gear box surface temperature should not exceed 30 ℃. Metering pump gearbox temperature should not exceed 20 ℃.

3, the ambient temperature is lower than 28 ℃, the average temperature before and after the insulation surface of the spinning box should not exceed 65 ℃.

4, pipeline connections shall not be leaked.

5, hair dryer wind speed should be stable, silk Cambodia no significant swing or parallel wire phenomenon. The difference between the wind speed on the same horizontal plane of the single ring spinning unit shall not be more than 15, and the difference between the wind speeds on the same horizontal plane in the single side spinning unit shall not be greater than 20.

6, tow passage and tow contact parts should be smooth, not hanging wire.

7, biphenyl pipe should be gas-tight test specified value of the technical documents shall not leak.

8, spinning box should be GB 150 for manufacturing, testing and acceptance, and supervision by TSG R0004--2009.

9, the heat spinning box fixed temperature measurement point temperature difference should not exceed 2 ℃.

10, electric heating of the spinning head temperature of the fixed temperature difference should not exceed 3 ℃.

11, screw extruder temperature control accuracy of the district should be ± 2 ℃.

12, screw extruder melt pressure control accuracy should be ± 0.3 MPa.

13, the metering pump should comply with the provisions of FZ / T 92026.

14, spinneret shall comply with the provisions of FZ / T 92038.

15, electrical equipment and wiring insulation, insulation resistance ≥ 1 Mi2.

16, metal shell protective grounding reliable, grounding resistance ≤ 0.1 Q.

17, electrical components should be able to withstand 1 min pressure test, test voltage ≥ 1500 V, can not withstand the above high-pressure components must be tested when disconnected.

18, Spinning machine coating should be consistent with the provisions of FZ / T 90074.

Many people think that the normal operation of the machine does not have time to monitor, and unfortunately, this idea is wrong. First of all, different rules in different industries, the textile industry, the operation of polypropylene spinning machine, there are matters needing attention, the spinning process is a fine job, the machine is not right, it will cause mistakes, causing the butterfly effect. So, learning these precautions is necessary.
