4.4 The vulcanizing tank must have a device to measure and display the pressure and temperature inside the tank. 4.5 The automatic control vulcanizing tank should be able to automatically adjust the pressure and temperature inside the tank according to the given vulcanizing process during a complete vulcanization cycle.
4.6 The temperature difference between the upper and lower parts of the inner cavity working area of ​​the indirect heating vulcanizing tank should not exceed 4°C, the temperature difference between the front and rear ends should not exceed 8°C, and the temperature difference between the inner cavity working area of ​​the direct heating vulcanizing tank should not exceed 10°C. 4.7 The vulcanizing tank should have a device to discharge condensed water. 4.8 The motor of the vulcanizing tank should be a closed motor. 4.9 The selection of the head and body materials of the vulcanizer shall comply with the provisions of GB150. 4.10 When a strong corrosive medium is generated during the vulcanization process, the vulcanizer shall be made of corresponding corrosion-resistant metal materials (or anti-corrosion measures shall be adopted).
4.11 The design, processing, welding, assembly, non-destructive testing and inspection of the main pressure-bearing parts of the vulcanizer shall be carried out in accordance with the relevant provisions of GB150.
4.12 The cumulative working time of the vulcanizer before the first failure shall not be less than 400h. Under normal operating conditions, the safe working time of the vulcanizer shall comply with the provisions of Table 2. 4.13
5 Safety requirements
The safe working time shall not be less than
5.1 When the use of the vulcanizer exceeds the safe working time, it shall be inspected in accordance with the relevant provisions of the "Regulations on Safety Supervision of Pressure Vessels" to determine whether it can continue to be used.
5.2. The vulcanizer shall have a safety device that can only open the tank cover when there is no pressure in the tank. 5.3 The vulcanizer should be equipped with a safety valve
5.4 The vulcanizer should be equipped with a device to prevent the tank cover from loosening during the vulcanization process. 5.5 The noise sound pressure level of the vulcanizer during operation shall not be greater than 80dB (A). 5.6
The vulcanizer should have a structure that is easy to hoist. 6 Test methods
6.1 Idle operation test
6.1.1 After the vulcanizer is assembled and the weld quality inspection is qualified, it must be tested and inspected according to the following items:. According to the requirements of Article 4.2, check the opening, closing and locking of the tank cover: the number of working cycles of the manual control test shall not be less than 5 times; the number of working cycles of the automatic control test shall not be less than 10 times; the action shall be flexible, accurate and reliable; b. Check the reliability of the safety device according to the requirements of Article 5.4. 6.1.2 For the indirect heating type vulcanizing tank, the gas circulation device shall be tested for no less than 1h of idling operation, and the bearing temperature rise shall not be greater than 20℃.
6.2 Water pressure test
HG2265-92
6.2.1 After each vulcanizing tank passes the idling test, a water pressure test must be carried out. The test pressure, time and rental method shall comply with the relevant provisions of GB150, and the weld shall not leak. 6.2.2 The pipeline system of the vulcanizing tank must be subjected to a water pressure test. The test pressure is 1.5 times the working pressure, and the pressure is maintained for 20 minutes without leakage.
6.3 Load operation test
5.3.1 Load operation test can only be carried out after the idling and water pressure tests are passed. 6.3.2 The continuous load operation time shall not be less than 2h. Check the following items: Check the accuracy and reliability of each control device according to the requirements of 4.2~4.5; Place the thermometer at the appropriate position of the vulcanizer (without sulfide) at the working pressure and working temperature. Measure the temperature difference in the tank b.
:
Check the reliability of the safety device according to the requirements of 5.1 and 5.2; Use a sound level meter to measure the noise sound pressure level of the vulcanizer during operation; d.
The motor power of the gas circulation device should not be greater than the rated power value. e.
