Embodiment Construction

[0024] The present invention will be further described below in conjunction with embodiment:

[0025] A chiller assembly process, comprising the steps of:

[0026] 1) For turning or tapping various pipe joints, 6~8 threads should be screwed in according to the standard joints, and the thread accuracy should be guaranteed to be 6~7 grades;

[0027] 2) For copper tubes that must be pressed into the cone, the wall thickness must be greater than 0.8 to ensure the roundness, angle and roughness of the cone, and there is no pinch in the clamping part;

[0028] 3) When bending the pipe, the core head of the pipe bend should be adjusted to the center line of the core head semicircle, and it is best to adjust it to be tangent to the center line of the pipe bending die circle on the pipe bending machine, and no scars are allowed inside and outside the pipe;

[0029] 4) When the copper pipe pipeline is arranged, the corresponding process springback line should be arranged. The springbac...

Abstract

The invention discloses a water chiller assembly process. The water chiller assembly process mainly comprises the following steps that firstly, turning or tapping is conducted on various pipe joints, wherein six to eight threads are screwed into each pipe joint according to the requirements of a standard joint, and it should be guaranteed that the thread accuracy ranges from the sixth level to the seventh level; secondly, a copper pipe needing to be subjected to taper opening pressing is required to meet the conditions that the wall thickness of the cooper pipe is larger than 0.8, the taper pressing roundness, the angle and roughness are guaranteed, and it is guaranteed that the clamping portion is free of damage caused by clamping; fifthly, the space between pipe contour edges of pipelines in the same row or spacial crossed pipelines should be larger than or equal to 50, and the space between the pipe fitting contour edges should be larger than or equal to 80; fourteenthly, when a compressor is mounted, the fastening pressure should be properly applied to the extent that an elastic cushion is pressed to be even, and capillary tubes are easily close to other workpieces in the mounting process, so that the space between the capillary tubes and the workpieces should be kept over 10 mm; and fifteenthly, in the leakage test, the test pressure ranges from 11 kg / cm<2> to 13 kg / cm<2>, the dwell time is longer than 48 hours, and all the portions of the pipelines should be free of leakage.

Description

technical field [0001] The invention relates to a chiller assembly process. Background technique [0002] The existing chiller assembly process has uncoordinated and unreasonable process steps, sometimes resulting in repeated or over-processing, which seriously affects product quality, and the scrap rate is high, requiring high operating skills for employees, resulting in high product costs. high. [0003] In addition, the existing chiller assembly 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 chiller assembly process 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 assembly process, comprising the steps of: [0007] 1) For turni...
