Variable-frequency pump wax injection system

Abstract

The invention discloses a variable-frequency pump wax injection system comprising a wax storage groove, a work groove, a variable-frequency pump and a clamp groove. The wax storage groove conveys liquid wax into the work groove through a work pipeline by means of a pump. The variable-frequency pump is arranged in the work groove and connected with one end of a wax injection pipeline. The other endof the wax injection pipeline is connected with a wax injection spray nozzle. The wax injection spray nozzle is fixed to a wax injection clamp. The wax injection clamp is arranged in the clamp groove. The variable-frequency pump wax injection system has the beneficial effects that the variable-frequency pump providing different flows of liquid wax for each cavity area is arranged in the work groove, and flow control can be achieved through control over the rotation speed of the variable-frequency pump. The variable-frequency pump adopting different rotation speeds for different injection points enables cavities of different volumes to achieve the full wax state at the same time, so that the wax loss can be reduced, the number of follow-up processing steps can be reduced, and operation andadjustment are convenient.

Description

technical field [0001] The invention relates to a system for protecting the cavity of an automobile body with liquid wax, in particular to a wax filling system with a variable frequency pump. Background technique [0002] In order to improve the anti-rust performance of the automobile body, especially the inner cavity of the body that cannot be reached by paint spraying, the cavity wax injection technology was invented and promoted. There are multiple wax injection points in a single body-in-white. Different wax injection points have different consumption of wax oil. The existing wax injection technology directly injects wax oil into the inner cavity at the same speed until it is completely filled. The volume of the cavity requires the injection speed, resulting in waste of wax oil. Contents of the invention [0003] In order to solve the defects existing in the prior art, the present invention provides a variable frequency pump wax injection system which reduces the loss...
