Maintenance of tiltable jacketed cooking pot
The use of the steam jacketed cooking pot must be maintained well, so as to achieve the purpose of long-term use and safety, so today I will introduce the maintenance of the jacketed cooking pot.
1. If steam leaks from the inlet pipe and outlet pipe joints, when tightening the nut can not solve the problem, you should add or replace the packing.
2. The pressure gauge and safety valve should be checked regularly, and should be replaced and repaired in time if there is any failure.
3. After 50 hours of use, remove the reducer and drain the lubricating oil, clean it with kerosene or diesel, and add 30 #-40 # clean engine oil. After 150 hours of use, the oil should be changed a second time. After that, the oil should be changed every 1000 hours or so according to the specific situation.
4. If the anti-rust oil peels off, it should be painted in time and the paint of the outer pot should be painted. Recommend X55-3 aluminum powder vinyl waterproof paint.
5. After the pot has been used for 5 years, it is recommended to carry out a safe water pressure test, and the interval of the subsequent water pressure test shall be carried out according to the requirements of the local technical department.
The pressure p water of the hydrostatic test is determined according to the following conditions:
When the rated working pressure P is 0.3MPa, P water=0.15MPa
When the rated working pressure pAmount=0.6-0.8MPa, pWater=pAmount=0.3MPa
6. The outer pot body of this kind of pot is made of 4mm~12mm thick steel plate, and the steel grade is A3. When the outer pot rusts and becomes thinner than 2mm for many years, stop using it.
7. For the welding of stainless steel and other stainless steel joints, stainless steel electrodes Austenitic 102, Austenitic 107, Austenitic 132, Austenitic 137 should be used, and other brands should not be used.
In actual use, stainless steel is slightly inferior to carbon steel in weldability, and there is the possibility of environmental cracking in the chloride ion environment, so it is prone to cracks. Users should pay more attention when using it. There are places where such problems are particularly prone to occur. For example, in the fillet weld between the steam inlet and outlet pipe and the jacket, the joint between the weld and the jacket is easy to crack. The stress is concentrated at this position. The inlet nozzle is the steam inlet, which is vulnerable to steam impact and the output temperature difference changes; at the same time, the connecting pipe also plays a role in supporting the weight of the container and the weight of the material in the pot. When unloading, it is necessary to rotate the connecting pipe to support the container tilting at a certain angle, and it is easy to cause fatigue crack sources when rotating back and forth. After long-term use, penetration cracks are prone to occur.
Here, pay more attention to the use and inspection. Check for cracks in the fillet welds of the inlet nozzle and jacket. Other fillet welds are more prone to cracking than butt welds, because fillet welds are more stressed.
Many jacketed cooking pots use the structure of a sandwich pot, so there will be such a problem. You must check more when you use it. If there is a problem, the equipment is basically repaired and the service life will not be long, because it is likely that the overall The structure has changed, and such jacketed cooking pot equipment has been used for a certain number of years, so it is recommended to directly replace the jacketed cooking pot.
