在保养修车的过程中，我们消费者怕的是买到不合格的配件，虽说备件小，但对车来说影响可以很大的呢。而我们也确实常常在为不小心买了假冒伪劣配件和不合用配件而烦恼。那么，如何才能买到合格合用的配件呢?新中昌告诉您保养维护选购爆破器材运输车配件八项注意

　　1。保护层的表面状况良好。大多数的部位涂上保护层的工厂。如活塞销，用石蜡保护轴承;活塞环，缸套表面涂防锈油和纸包装;阀，活塞，等浸防锈油与塑料袋封装后。选购时，如果发现损失或损坏密封套，包装纸丢失，防锈油或石蜡，应退还。

　　2。该胶接件有无松动。由两个或两个以上零件，配件，零件的压力设备，粘接或焊接之间，他们之间有无松动现象，如油泵柱塞通过安装组合调整臂;离合器从动皮带轮和钢板铆接，摩擦片和钢片铆钉或胶水纸过滤器骨架;和滤纸胶接线头;电气设备的焊接在一起。如果发现松动选购时，应改变。

　　3。如果移动部分灵活。油泵选购的时候转动部件的装配，用手转动泵轴，不应该结合感觉灵活;当滚动轴承的选择和购买，支持轴承内圈，外圈，外圈和另一方面应该能够很快转，然后逐步停止。如果移动的部件是铸铁，内部腐蚀或变形，不买。

　　4。看组装配件齐全。完整的正式装配零件必须处于良好的状态，以确保顺利安装和正常运行。一些组件如果包装上的个别小零件，使组件将无法正常工作甚至报废。

　　5。商标标志是否完整。对真实的产品包装上的笔迹是质量好，包装是明确的，叠印色彩应鲜艳。包装盒，袋，应标明产品名称，规格，数量，注册商标，名称，地址和电话号码，等，有些厂家还打上标记的部分。一些重要部件如发电机和分销商，喷油泵，章还附有说明书，证书，以及检查，指导用户正确使用维护。选购时，应仔细辨别，如果购买假冒伪劣产品。

　　6。看到几何不变形。部分因为不当的生产，运输，储存，容易变形。检查，轴类零件可沿玻璃板轧制一圈，看到部分和玻璃层压来判断是否有任何泄漏出来的光弯曲;离合器从动盘钢或摩擦片的选择和购买，可以解除，摩擦片的钢的眼睛观察屈曲;油封选购时，骨架油封应积极面对圆形，扁平玻璃层压无变形;无骨架油封外边缘应平直，用手变形，应该能够放下后恢复。选购时各种垫片，还应注意检查几何尺寸及形状。

　　7。看看结合场地平整。在处理，存储过程的零件，由于振动和撞击，经常与部位产生毛刺，压痕，破损，裂缝的组合，或影响零件的使用。选购时要注意检查。

　　8。零件表面有锈。合格的零件表面，既有一定的准确度和抛光，更为重要的部分，精度更高，更严格的防锈包装。选购时要注意检查，如果发现部分锈斑，霉变的斑点或橡胶零件裂纹和失去弹性，线，或轴颈表面具有明显的工具应该改变。

　　In the process of maintenance repair, consumers are most afraid of is we buy the unqualified parts, although small spare parts, but impact can be huge for the car? But we do often for accidentally bought counterfeit parts and don't share parts. So, how do you buy a share of qualified parts? New chang told you in the maintenance of choose and buy blasting equipment truck accessories eight note

　　1. The protection surface layer are in good condition. Most of the parts are coated with protective layer in the factory. Such as piston pins, bearings with paraffin wax protection; Piston ring, cylinder liner surface coating anticorrosive oil and paper package; Valve, piston, etc after immersion rust-proof oil encapsulated with plastic bag. When the choose and buy, if find seal set of loss of damage, loss of wrapping paper, rust-proof oil or paraffin, shall be returned.

　　2. The glue joint parts with and without loose. By two or more than two parts, accessories parts by pressure equipment, adhesive or welding between, between them there is no loose phenomenon, such as oil pump plunger and adjust arm through a combination of installation; Clutch driven pulley and steel sheet is riveting, friction plate and sheet steel is riveting or glue; Paper filter filter skeleton and filter paper was glued joint; The thrum of the electrical equipment is welded together. If found loose when the choose and buy, should be change.

　　3. If moving parts are flexible. Oil pump of choose and buy when rotating components assembly, turn the pump shaft by hand, should feel flexible without binding; When rolling bearing of choose and buy, support the bearing inner ring, outer ring, and with another hand outer ring should be able to quickly turn, and then gradually to a halt. If the moving parts are in irons, the internal corrosion or deformation, don't buy.

　　4. See the assembly parts are complete. Complete formal assembly parts must be in good condition, to ensure smooth assembly and normal operation. Some assembly parts if individual small parts on the packing, will make the assembly components will not work even scrapped.

　　5. Whether trademark logo is complete. The handwriting on the authentic product packaging are of good quality and package is clear, overprint colors should be bright. Packing box, bag, should be marked with product name, specifications, quantity, registered trademark, name, address and telephone number, etc., some manufacturers still hit their mark on the parts. Some important parts such as generators and distributors, fuel injection pump, chapter also comes with instructions, certificates, and inspectors, to guide users to the correct use of maintenance. When the choose and buy, should carefully identify, in case to buy the fake and inferior products.

　　6. See the geometry without deformation. Some parts because of improper manufacture, transport, storage, easy to deformation. Check, axial parts along the glass plate rolling can be a circle, see parts and glass laminating to judge whether any light-leaking bending; Clutch platen steel or friction slices of choose and buy, can to lift, friction plate of the steel in the eyes to observe whether the buckling; Oil seal when the choose and buy, the skeleton oil seal should face positively the circular, with flat glass laminating without deflection; Frameless oil seal outer edges should be straight, with hand deformation, should be able to recover after let go. When the choose and buy all kinds of gasket, also should pay attention to check the geometry size and shape.

　　7. See if combining site is flat and level. Spare parts in the process of handling, storage, due to the vibration and knock against, often in combination with parts produce burr, indentation, breakage, crack, or affect the use of the parts. When the choose and buy should pay attention to check.

　　8. The parts surface have rust. Qualified spare parts surface, there are both certain accuracy and polished finish, the more important parts, precision is higher, more rigorous rustproof packaging. When the choose and buy should pay attention to check, if found parts with rust spots, mildew spots or rubber parts cracked and lose elasticity, lines, or shaft neck surface has obvious tool should be change.
