The testing of spiral plate heat exchangers and some precautions have not been introduced in the previous articles, so the following will explain this aspect so that you can understand it through the website. Then, let's expand the specific content, hoping to give you some useful knowledge.
First, the test run of the spiral plate heat exchanger
1. Preparation before the test run
(1) Complete all the maintenance content, and the maintenance quality meets the specified requirements. Clean the entire system, check the instruments, safety accessories, etc. to see if they are complete and sensitive.
(2) Drain the air in the heat exchanger and clean up the construction site.
2. Test drive
(1) Heating and cooling should be gradual, without jumping, so as not to make the pressure difference too large or cause thermal shock.
(2) During the test run, it is necessary to observe whether there are any abnormal noises, leaks, etc. If so, it should be dealt with in time. If not, it indicates that the test run has met the specified requirements.
3. Precautions
(1) Inspect blind plates, pipes, valves, filters, and safety devices to see if they meet the specified requirements.
(2) The water and gas in the equipment should be drained to ensure safe operation.
Precautions for spiral plate heat exchangers
1. Operators should operate in strict accordance with process operating procedures, etc. Heat exchangers cannot be used over temperature or pressure.
2. If used in winter, avoid being frozen.
3. After the system is shut down, the cooling and pressure-lowering operations should be carried out in strict accordance with the operating procedures.
4. During the maintenance process, the scaffolds, safety nets, etc. used must comply with safety technical regulations. If it is working at a height, take safety measures to avoid danger.
