The cleaning methods of air compressor parts can be roughly divided into two types: chemical cleaning and high-pressure water jet cleaning. The two cleaning methods can be said to have their own advantages. Today, the editor will first introduce you to high-pressure water jet cleaning. High-pressure water jet cleaning uses the high-pressure water produced by a plunger pump to spray to the scale layer through a special nozzle. The scale removal is thorough and efficient. However, the installed container is large and consumes a lot of water. In addition, what issues we need to pay attention to during the cleaning process What?
Ultrasonic descaling:
It mainly uses ultrasonic sound field to treat fluid, so that the physical form and chemical properties of the fouling substance of the fluid undergo a series of changes under the action of the ultrasonic field, so that it is dispersed, crushed, loosened, loosened and not easy to adhere to the product formed by the pipe wall. dirt. The anti-fouling mechanism of ultrasound is mainly: A. Cavitation effect; B. Activation effect; C. Shear effect; D. Inhibition effect.
Descaling of the mobile descaler in the pipeline:
The new type of mobile descaler in the pipeline has higher efficiency and good quality, and is suitable for descaler of oil and gas transportation pipelines, chemical liquid and water transportation pipelines.
According to different driving methods, the typical mobile descaling equipment in the pipeline is divided into: A. Electric drive mobile descaling equipment; B. Hydraulic driving mobile descaling equipment; C. Compressed air driving mobile descaling equipment.
It relies on mechanical action to provide a force greater than the adhesion force of dirt to cause dirt to fall off the heat exchange surface. This method can remove carbonized dirt and hard dirt that cannot be removed by chemical methods, but it generally takes 5-6 times to clean the dirt layer in the pipe, sometimes as many as 10 times, and the pigging efficiency is low and the quality is poor.
Operation steps for mechanical cleaning of straight tube heat exchanger:
1. Prepare the air compressor and water source;
2. Remove the short joint on the water pipe of the heat exchanger;
3. Unscrew the fastening bolts of the heat exchanger head and rotate the head 180 degrees to expose the heat transfer tube;
4. Insert the nylon brush into the heat transfer tube until the air block on the nylon brush completely enters;
7. Push the nylon brush back from the other end of the heat exchanger and repeatedly brush and scrape more than 3 times;
8. Flush the heat transfer tube with water with a pressure of 0.3MPa;
9. Change a heat transfer tube and repeat the above 3 steps until all the heat transfer tubes have been washed;
10. Check the color inside the heat transfer tube, if the copper color is exposed, the washing is qualified;
11. Turn the head back, check whether the sealing gasket of the head is flat, and tighten the fastening bolts of the heat exchanger head;
12. Connect the short joint on the water pipe of the heat exchanger;
13. Cheong manage the scene.
