Chemical plating reinforcing method and apparatus for airborne tank internal surface protection

Abstract

The invention discloses a chemical plating strengthening method and device for the protection of inner surfaces of airborne oil tanks and comprises the steps of chemical oil and rust removal, a first water washing, ni-p chemical plating, ni-p-zn chemical plating, a second water washing and heat treatment; the invention also discloses a chemical plating strengthening device for realizing the chemical plating strengthening method for the inner surfaces of airborne oil tanks and comprises a liquid storage tank, a plurality of three-way pipes, a plurality of hoses, a plurality of composite pipes,a liquid pump, an airborne oil tank and a fluid infusion pipe; the airborne oil tank is arranged in a heating furnace; a strengthening plating layer of the invention is divided into two layers with an internal layer of the ni-p chemical plating and an external layer of ni-p-zn chemical plating, and the strengthening layer is integrally an anode plating layer and has a good combination power with a substrate of the airborne oil tank; the device is simple in operation and easy in controlling; the device is high in heating speed and good in heat preserving effect and saves energy resources; the whole process of plating and cleaning is closed without the evaporation of liquid under good working environments; the cycle of the plating liquid can be realized through the liquid pump and compared with the standing plating, the plating layer is more uniform and the gap efficiency is lower.

Description

technical field [0001] The invention discloses a technology for protecting the inner surface of an oil tank. In particular, it relates to an electroless plating strengthening method and device for protecting the inner surface of an airborne fuel tank. technical background [0002] The on-board fuel tank is a special fuel tank used in large-scale mining and excavating machinery. The material of the fuel tank is ordinary carbon steel, and there is a mesh partition inside the fuel tank. The main problem is that the inside of the fuel tank is inconvenient to clean after manufacture, and it is easy to rust. When in use, the rust products will block the mesh partition and pollute the oil, affecting the normal use of the fuel tank. The mesh partition in the fuel tank is Irreplaceable. In the current surface strengthening method, electroplating is difficult to achieve plating on the inner surface, especially when there is a mesh separator; the ordinary electroless nickel plating ...

Problems solved by technology

The main problem is that the inside of the fuel tank is inconvenient to clean after manufacture, and it is easy to rust. When in use, the rust products will block the mesh partition and pollute the oil, affecting the normal use of the fuel tank. The mesh partition in the fuel tank is irreplaceable

In the current surface strengthening method, electroplating is difficult to achieve plating on the inner surface, especially when there is a mesh separator; the ordinary electroless nickel plating layer is a cathodic plating layer, and when there are pores in the plating layer, it will cause oil tank The local corrosion of the oil tank will lead to the perforation of the oil tank in severe cases, shortening the service life of the oil tank, and the generation of pores cannot be avoided during electroless plating
