Abstract

The invention relates to a device which uses new composite particle nickel base alloy to manufacture and repair cylinder jackets and is used to repair the inner wall of the cylinder jackets of large power diesel engines after abrasion due to use. The device comprises a cylinder jacket (1) which needs manufacturing, a lower water hat (2), an upper water hat (3), a stirring rod (12), a condenser (5), a filter pump (6), a liquid mixing tank (7), a heater (10), a partial feeding device (11) and the stirring rod (12), wherein the lower portion of the cylinder jacket (1) which needs manufacturing is connected with the lower water hat (2) in a sealed mode, the upper portion is connected with the upper water hat (3) in the sealed mode, the stirring rod (12) is arranged in the cylinder jacket (1) which needs manufacturing, the lower portion of the lower water hat (2) is communicated with an outlet of the partial feeding device (11), the upper portion of the upper water hat (3) is communicated with an inlet of the condenser (5), the outlet of the condenser (5) is connected with the filter pump (6), the filter pump (6) is connected with the liquid mixing tank (7), the liquid mixing tank (7) is connected with a solution inlet of a liquid storage tank (8), a solution outlet of the liquid storage tank (8) is communicated with the solution inlet of the heater (10), and the solution outlet of the heater (10) is communicated with the solution inlet of the partial feeding device (11). The inner wall of the cylinder jackets after abrasion due to use can be repaired to the original size to be used continuously through utilizing the device of the invention.

Description

Technical field [0001] The invention relates to a device for manufacturing or repairing a cylinder liner with a new type of composite particulate nickel-based alloy. It is mainly used to repair the inner wall of the existing railway, marine and high-power diesel engine cylinder liners after use and wear. It can also be used to coat the inner wall of the cylinder liner of various high-power diesel engines to improve its performance. Background technique [0002] Existing railway, marine and high-power diesel engine cylinder liners, after use, the inner wall is worn, the power decreases, and the fuel consumption increases, so they are scrapped. [0003] "Composite particulate nickel-based alloy" is developed on the basis of the widely used electroless nickel-based alloy coating. That is, high-hard ultra-fine silicon carbide particles are added to the original electroless nickel-based alloy coating to make the coating harder and have better oil content under working conditions. The ...

AI Technical Summary

Problems solved by technology

Any impurities in the solution, especially the presence of catalytically active particles will accelerate the decomposition of the solution, while the "composite particle nickel-based alloy" process is just the opposite. A large number of fine particles must be added to the solution, and the surface area of ​​the particles generally reaches 100,000 cm2 / liter, the loading capacity is more than 800 times that of the original process (the loading capacity refers to the surface area of ​​the solution corresponding to the unit volume of the coated workpiece as the loading capacity, and the unit is 100L / m 2 ), so the solution is quickly decomposed and scrapped and cannot work normally for a long time, so the coating can generally only be prepared in the laboratory and cannot be used in industrial applications.
