Abstract
The present invention relates to wear and cavitation erosion preventing protection method for blower, water pump and other vane machines. The method includes the following steps: hot pressing some metal net into polymer material to form one wear and cavitation erosion resisting reinforced polymer material layer on one side and exposed metal layer in certain thickness on the other side; roughening the metal surface to be protected and scrubbing with acetone; and adhering the exposed metal layer of the facing layer with epoxy resin to the surface to be protected. The method forms firm and smooth wear and cavitation erosion resisting surface to protect the vane wheel surface. The method may be used also for the protection of the surface of tank for storing corrosive medium.
Description
Technical field
The present invention relates to a kind of wear-resisting anti-cavitation protection method that is used for protecting the local surfaces of the easy to wear and cavitation of turbomachines such as blower fan, water pump.
Background technique
In turbomachines such as blower fan, water pump, local surfaces wearing and tearing and cavitation especially severe so that scrap entire equipment, influence the safety and economic operation of pump and blower fan greatly.Therefore, to local anti-cavitation and the wear Protection particular importance that seems of strengthening of rotary machines such as pump and blower fan, yet, to these surfaces, do not take special protective measures for many years, in recent years, with 1321 ceramic particle coating of U.S. berzona company certain effect of resistance to wearing is arranged, resisting slight cavitation with 1341 coating of the said firm has effect.But fail to deal with problems at all.
Summary of the invention
The objective of the invention is in order to solve in the turbomachines such as blower fan, water pump, the problem of local surfaces wearing and tearing and cavitation provides a kind of protecting method of wear-resisting anti-cavitation.
Technological scheme of the present invention is: method may further comprise the steps:
1) through cleaning and reserve the certain thickness wire netting, be pressed in the macromolecular material with hot-press method, with polymeric adhesive material together, polymer material layer one side after wire netting strengthens forms wear-resisting anti-cavitation and strengthens macromolecular material veneer thin layer, and opposite side has the certain thickness wire netting for revealing;
2) to need corrosion-resistant metal surface hacking, use the acetone scrub;
3) wire netting that is exposed to macromolecular material one side pastes on the metal surface of the turbomachine that needs protection by epoxy resin.
Owing to wire netting and macromolecular material are bonded together with hot-press method; form wear-resisting anti-cavitation and strengthen macromolecular material veneer thin layer; its surface is smooth; has characteristic wear-resistant, anti-cavitation; be exposed to the outer wire netting of polymer material layer and arrive the metal surface that needs protection with epoxy bond; they bond very firmly, and therefore, this method just can play the good protective action reliably of anti-cavitation, abrasionproof to the localized metallic surface of turbomachine.This method also can be used for the anticorrosion of surface such as the jar, groove of contain Korrosionsmedium.
Description of drawings
Fig. 1 is the wear-resisting anti-corrosion layer structure of anti-cavitation schematic representation;
Fig. 2 is that the wear-resisting anticorrosive coat of anti-the cavitation is pasted schematic representation.
Embodiment
This method is done an explanation in conjunction with the accompanying drawings: method may further comprise the steps:
1) by shown in Figure 1, cleaning is also reserved 0.1-0.8mm thickness wire netting 1, be pressed in the macromolecular material 2 with hot-press method, with polymeric adhesive material together, polymer material layer one side after wire netting strengthens forms wear-resisting anti-cavitation and strengthens macromolecular material veneer thin layer, opposite side has 0.1-0.8mm thickness wire netting for revealing, macromolecular material can be used ultra-high molecular weight polyethylene UHMW-PE, high density polyethylene (HDPE) etc., wire netting is steel wire, copper mesh or aluminium wire netting etc., and is better with steel wire;
2) to need corrosion-resistant metal surface hacking, use the acetone scrub;
3), paste on the metal surface 4 that needs protection by epoxy resin 3 with the wire netting 1 that is exposed to macromolecular material one side by shown in Figure 2.
Claims (3)
1, the anti-corrosion method of a kind of turbomachine concentrated wear and cavitation is characterized in that method may further comprise the steps:
1) cleaning and reserve certain thickness wire netting (1), be pressed in the macromolecular material (2) with hot-press method, with polymeric adhesive material together, polymer material layer one side after wire netting strengthens forms wear-resisting anti-cavitation and strengthens macromolecular material veneer thin layer, and opposite side has the certain thickness wire netting for revealing;
2) to need corrosion-resistant metal surface hacking, use the acetone scrub;
3) paste on the metal surface (4) that needs protection by epoxy resin (3) with the wire netting (1) that is exposed to macromolecular material one side.
2, the anti-corrosion method of a kind of turbomachine concentrated wear according to claim 1 and cavitation is characterized in that, the described thickness that is exposed at the outer wire netting of macromolecular material is 0.1-0.8mm.
