(2020 trip to Hubei) Wuhan Heavy Industry Casting and Forging Co., Ltd.

Address:Overpass of Heping Avenue, Qingshan District, Wuhan City, Hubei Province

Machine Model: 360KW

Number Of Devices: 1

Purpose:Heating lye in a link in sewage treatment

Solution:Heat 30 tons of sewage lye to 140 ℉, and then let the hot lye flow into the next process, working 5-6 hours a day.

On-Site Problem:The master inspected a total of 16 heating tubes of 360KW, one of which was completely burned out, and the current of 12 heating tubes was unbalanced, and only three of them could still work temporarily.

The Master Analyzes The Reasons:
1. The influent water treatment is not in place, and the water quality is too poor;
2. There is a strong alkali in the heating pool, and it is possible that the hot air in the pool flows back to the inner tank through the pipe.

The Master Solves On The Spot:
I changed a 24KW heating tube, and when I removed it, I found that there was a lot of scale in the heating tube.

Follow-Up:
1) Install water treatment;
2) Install a check valve at the steam port;
3) The equipment is equipped with a timer;
4) There are not enough heating tubes of the same type on the car, and the rest of the heating tubes will be replaced at the factory later.

Client Feedback:
1) It is required to emphasize the harm of not using soft water treatment according to the customer's industry while selling equipment;
2) Debugging personnel are required to teach customers more operation and use procedures in the early stage.
