Abstract
The present invention relates to a wearing resistance and cavitation erosion resistance protection method used for easy wearing and cavitation erosion partial surfaces of turbine machines of blowers, water pumps, etc. The method comprises the following steps: 1) reserving metal net with a certain thickness, and pressing the metal net into high molecular material by a hot press method; forming a wear resistance and cavitation erosion resistance strengthening high molecular material veneer thin layer on one side, and revealing the metal net with a certain thickness on the other side; 2) roughening the metal surface needing corrosion resistance, and scrubbing and cleaning the metal surface by acetone; 3) pasting the metal net exposed on one side of the veneer thin layer on the metal surface of the turbine machine needing protecting by epoxy resin. The strengthening high molecular material veneer thin layer is adopted, and the surface is slick; consequently, the present invention has the characteristics of wear resistance and cavitation erosion resistance. The metal net exposed outside the high molecular material layer is bonded to the metal surface needing protecting by the epoxy resin, and the bonding is very firm; consequently, the method can have cavitation erosion resistance and wearing resistance action on the partial metal surface of the turbine machine. The method can also be used for corrosion prevention of the surfaces of pots, grooves, etc. which are used 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) cleaning has certain thickness wire netting, be pressed in the macromolecular material with hot-press method, be bonded together with macromolecular material, 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 protection on surfaces such as the jar, groove of contain Korrosionsmedium.
Description of drawings
Fig. 1 is the wear-resisting layer of anti-cavitation protection structural representation;
Fig. 2 is that the wear-resisting layer of anti-the cavitation protection 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, be bonded together with macromolecular material, 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 0.1-0.8mm thickness wire netting, macromolecular material can use ultra-high molecular weight polyethylene, high density polyethylene (HDPE) etc. for revealing, 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, a kind of method that prevents turbomachine concentrated wear and cavitation is characterized in that method may further comprise the steps:
1) cleaning has certain thickness wire netting (1), be pressed in the macromolecular material (2) with hot-press method, be bonded together with macromolecular material, 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, a kind of method that prevents turbomachine concentrated wear and cavitation according to claim 1 is characterized in that, the described thickness that is exposed at the outer wire netting of macromolecular material is 0.1-0.8mm.
