一、齿轮泵表面粘涂原理及特点
近年来表面粘涂技术我国设备维修得到了广泛应用,适用于各种材质零件设备修补。其工作原理将加入二硫化钼、金属粉末、陶瓷粉末纤维等特殊填料胶粘剂,直接涂敷于材料或零件表面,使之具有耐磨、耐蚀等功能,主要用于表面强化修复。它工艺简单、方便灵活、安全可靠,不需要专门设备,只需将配好胶涂敷于清理好零件表面,待固化后进行修整即可,常室温下操作,不会使零件产生热功当量影响变形等。
二、粘涂层涂敷工艺
轴套外圆、轴套端面贴合面、齿轮端面或泵壳内孔小面积均匀性磨损量0.15-0.50mm之间、划痕深度0.2mm以上时,宜采用粘涂修补工艺。粘涂层涂敷工艺过程:初清洗→预加工→{zh1}清洗及活化处理→配制修补剂→涂敷→固化→修整、清理或后加工。
粘涂工艺虽然比较简单,但实际施工要求却相当严格,仅凭选择好胶粘剂,不一定能获得高粘涂强度。既要选择合适胶粘剂,还要严格地按照正确工艺方法进行粘涂合适胶粘剂,还要严格地按照正确工艺方法理行粘涂才能获得满意粘涂效果。
(一)涂敷
用修补剂先粘修表面上薄涂一层,反复刮擦使之与零件充分浸润,然后均匀涂至规定尺寸,并留出精加工余量。涂敷尽可能朝一个方向移动,往复涂敷会将空气包裹于胶内形成气泡或气孔。
(二)预加工 用细砂纸磨成一定沟槽网状,露出基体本色。 (三){zh1}清洗及活化处理
用丙酮或专门清洗剂进行。然后用喷砂、火焰或化学方法处理,提高表面活性。 (四)修整、清理或后加工
进行精镗或用什锦锉、细砂纸、油石将粘修面精加工至所需尺寸 (五)配制修补剂
修补剂使用时要严格按规定比例将本剂(A)固化剂(B)充分混合,以颜色一致为好,并规定时间内用完,随用随配。 (六)初清洗
零件表面{jd1}不能有油脂、水、锈迹、尘土等。应先用汽油、柴油或煤油粗洗,{zh1}用丙酮清洗。 (七)固化
用涂有脱模剂钢板压工作上,一般室温固化需24小时,加温固化(约80℃)需2-3小时。

1, the gear pump principle and characteristics of surface coating
In recent years, surface coating of our equipment maintenance has
been widely used for a variety of materials spare parts and
equipment repair. It works to join the molybdenum disulfide, metal
powder, ceramic powder filler fiber and other special adhesive
coating on the materials or components directly to the surface, so
that with wear, corrosion and other functions, mainly used for
surface hardening repair. It process simple, convenient and
flexible, safe and reliable, no special equipment, just with good
rubber coating on the cleared part surface can be trimmed after curing, constant
room temperature operation, does not make parts produce mechanical
equivalent of heat impact deformation. Second, sticky coating
coating process Cylindrical sleeve, sleeve end fitting surface, the
gear pump shell hole end or even a small area of wear between
0.15-0.50mm, 0.2mm above the depth of scratches, should use sticky
coating repair process. Adhesive coating during the coating
process: first pre-processing → Cleaning → activation → final
cleaning and preparation of repair agent curing → → → coating
finishing, cleaning or after processing. Cohering technique is a
relatively simple, but the actual construction requirements are
very strict, a good adhesive choice alone does not necessarily have
access to high-viscosity coating strength. We must choose the right
adhesive, but also strictly in accordance with the correct method
of cohering technique suitable adhesive, but also strictly in
accordance with proper methods of handling line process to a
satisfactory coating of adhesive coating effect. (A) Coated Putty
stick with the first thin coat repair the surface, repeated scratching and
parts so that the full invasion, and then uniformly coated to the
required size, and allow precision machining allowance. Coating as
moving in one direction, reciprocating air parcels in the plastic
coating will form a bubble or pore within. (B) pre-processing
Ground into a certain groove with fine sandpaper network, exposing
the substrate character. (C) the final cleaning and activation With
acetone or specialized cleaning agents. Then sandblasting, flame or
chemical means, and improve the surface activity. (D) repair,
cleaning or after processing For fine boring or needle files, fine
sandpaper, shaving finishing whetstone will stick to the required
size (E) preparation of Putty Putty when used strictly in
accordance with the provisions of proportion to the agent (A)
curing agent (B) well-mixed, color-line as well, and used within
the specified time, with the use allocation. (F) Initial cleaning
Part surface must not have oil, water, rust, dust, etc.. Should use
gasoline, diesel or kerosene rough wash, and finally washed with
acetone. (G) curing Pressure plate coated with release agent with
the work, generally take 24 hours at room temperature curing, heat
curing (about 80 ℃) take 2-3 hours.
