Embodiment Construction

[0021] The present invention will be further described below in conjunction with embodiment:

[0022] A chiller surface treatment process, comprising the steps of:

[0023] 1), surface pretreatment

[0024] Before the workpiece is painted, the scale, rust, welding slag, dust, grease and other dirt on the surface must be completely removed, otherwise, not only the adhesion of the paint film will be affected, but the scale and rust will continue to develop under the paint film , or even the paint film will fall off together, which will affect the service life of the car. Therefore, the surface of the workpiece must be pretreated before painting.

[0025] 1.1) Hit the weld seam with a beveling hammer to remove the coating and clean up the welding slag;

[0026] 1.2) Grind and polish the weld seam with a grinder;

[0027] 2), fuel injection treatment

[0028] 2.1) Check whether the air pressure of the spray gun is normal (the air pressure should be between 0.5~0.6Mpa);

Abstract

The invention discloses a surface treatment process for a water chiller. The surface treatment process comprises the following steps of 1) surface pretreatment; and 2) oil spraying treatment: 2.1) checking whether the air pressure of a spray gun is normal (the air pressure needs to range from 0.5Mpa to 0.6Mpa) or not; 2.2) preparing a pickling and phosphating liquid according to the specified rate, and carrying out concentration detection; 2.3) flushing a pickled workpiece to be clean with water in time, for example, finishing the treatment of a workpiece needing phosphating in time; 2.4) operating a workpiece subjected to surface cleaning and surface treatment by wearing water-free and oil-free clean gloves in the carrying process; 2.5) carrying out oil removal treatment on an iron workpiece not subjected to pickling, phosphating and sand blasting treatment; 2.6) spraying an antirust paint on the iron workpiece not subjected to pickling, phosphating and sand blasting treatment before ash scraping; 2.7) respectively preparing putty ash according to different workpiece materials; and 2.8) ensuring that the placing time of the cleaned workpiece does not exceed 4h, and carrying out the operation again if the placing time exceeds 4h.

Description

technical field [0001] The invention relates to a surface treatment process of a chiller. Background technique [0002] The existing chiller surface treatment process has uncoordinated and unreasonable process steps, sometimes repeated or excessive treatment, which seriously affects product quality, and the scrap rate is high, requiring high operating skills for employees, resulting in product costs. On the high side. [0003] In addition, the existing chiller surface treatment process steps are lengthy, and there are many unreasonable places in the allocation of each process. Contents of the invention [0004] In order to achieve the purpose of the present invention, the present invention provides a surface treatment process for chillers with reasonable and coordinated process arrangements. [0005] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0006] A chiller surface treatment pro...
