A wear-resistant and silent dual-rotor high-speed motor and its preparation method

Abstract

The invention discloses a wear-resistant and silent dual-rotor high-speed motor. The sound insulation board is composed of two components, A and B, in the ratio of A: B = 2:1. A and B contain the following components in parts by mass: A component Include the following components in terms of parts by mass: nano-silica powder: 11-19 parts, nano-zinc oxide: 9-12 parts, dimethylacetamide: 7-10 parts, methyl acetate: 3-8 parts , chloroprene rubber: 10-14 parts, tetraethyl orthosilicate: 8-12 parts, amino resin: 6-9 parts, auxiliary materials: 30-33 parts; the second component includes the following components by mass parts: Base emulsion: 17‑20 parts, antifreeze agent: 4‑8 parts, filler: 12‑19 parts, plasticizing resin: 3‑9 parts, vapor phase corrosion inhibitor: 1‑4 parts, curing agent: 20‑24 parts parts, defoamer: 19-22 parts, film-forming aids: 23-27 parts, the present invention not only improves work efficiency, but also reduces production cost and scrap rate, saves time and effort, high efficiency and energy saving, simple steps and convenient operation .

Description

technical field [0001] The invention relates to the technical field of centrifugal compressor motors, in particular to a wear-resistant and silent dual-rotor high-speed motor and a preparation method thereof. Background technique [0002] The high-speed motor rotor used in the DDR compressor runs more stably, and the system runs more reliably. However, the high-speed motor in the prior art is noisy when running at high speed. In the case of storing multiple devices, the working environment is very noisy. The working pressure of the staff is increased, and the rotor is prone to wear and tear under long-term activities, which greatly increases the scrap rate of the equipment. In order to reduce the scrap rate, improve work efficiency, improve the working environment, and save time and effort, the present invention proposes a A wear-resistant silent double-rotor high-speed motor and a preparation method thereof. Contents of the invention [0003] The technical problem to be ...
