1、看結合部位是否平整。自動(dòng)攪拌一體車(chē)零配件在搬運、存放過(guò)程中,由于振動(dòng)、磕碰,常會(huì )在結合部位產(chǎn)生毛刺、壓痕、破損或裂紋,影響自動(dòng)攪拌一體車(chē)零件的使用。選購時(shí)應注意檢查。
1. See if the joint is smooth. During the transportation and storage of concrete mixer parts, due to vibration and collision, burr, indentation, damage or crack often occur at the joint, which affects the use of concrete mixer parts. Pay attention to the inspection when purchasing.
2、看零件表面有無(wú)銹蝕。合格的自動(dòng)攪拌一體車(chē)零配件表面,既有一定的精度又有錚亮的光潔度,越是重要的零配件,精度越高,包裝防銹防腐越嚴格。選購時(shí)應注意檢查,若發(fā)現混凝土攪拌車(chē)零件有銹蝕斑點(diǎn)、霉變斑點(diǎn)或橡膠件龜裂、失去彈性,或軸頸表面有明顯車(chē)刀紋路,應予調換。
2. Check the surface of parts for corrosion. The surface of qualified concrete mixer parts has a certain precision and a bright finish. The more important the parts are, the higher the precision is, the more strict the anti rust and anti-corrosion of packaging is. When purchasing, pay attention to inspection. If the parts of concrete mixer truck are found with rust spots, mildew spots, rubber parts cracked or lose elasticity, or there are obvious turning tool lines on the surface of shaft neck, they should be replaced.

3、看轉動(dòng)部件是否靈活。選購機油泵等轉動(dòng)部件總成時(shí),用手轉動(dòng)泵軸,應感到靈活無(wú)卡滯;選購自動(dòng)攪拌一體車(chē)車(chē)滾動(dòng)軸承時(shí),一手支撐軸承內環(huán),另一手打轉外環(huán),外環(huán)應能快速自如轉動(dòng),然后逐漸停轉。若轉動(dòng)部件轉動(dòng)不靈,說(shuō)明內部銹蝕或產(chǎn)生變形,不要購買(mǎi)。
3. See if the rotating parts are flexible. When purchasing the oil pump and other rotating parts assembly, the pump shaft should be rotated by hand to feel flexible without sticking; when purchasing the rolling bearing of the concrete mixer truck, one hand should support the inner ring of the bearing, the other hand should rotate the outer ring, and the outer ring should be able to rotate quickly and freely, and then stop gradually. If the rotating parts do not work well, it means that the internal corrosion or deformation, do not buy.
4、看幾何尺寸有無(wú)變形。有些自動(dòng)攪拌一體車(chē)配件零件因制造、運輸、存放不當,易產(chǎn)生變形。檢查時(shí),可將軸類(lèi)零件沿玻璃板滾動(dòng)一圈,看零件與玻璃板貼合處有無(wú)漏光來(lái)判斷是否彎曲。
4. See if the geometry is deformed. Some parts of concrete mixer truck are easy to deform due to improper manufacture, transportation and storage. During the inspection, the shaft parts can be rolled along the glass plate for a circle to see whether there is light leakage at the joint between the parts and the glass plate to judge whether it is bent.
選購自動(dòng)攪拌一體車(chē)離合器從動(dòng)盤(pán)鋼片或摩擦片時(shí),可將鋼片、摩擦片舉在眼前觀(guān)察其是否翹曲;在選購油封時(shí),帶骨架的油封端面應呈正圓形,能與平板玻璃貼合無(wú)撓曲;無(wú)骨架油封外緣應端正,用手握使其變形,松手后應能恢復原狀。在選購各類(lèi)襯墊時(shí),也應注意檢查幾何尺寸及形狀。
When choosing the steel plate or friction plate of the clutch driven plate of the concrete mixer, you can lift the steel plate and friction plate in front of your eyes to observe whether they are warped; when choosing the oil seal, the end face of the oil seal with framework should be in a normal circle, which can fit with the flat glass without bending; the outer edge of the oil seal without framework should be straight, which should be deformed by hand, and can be restored to the original state after releasing. In the purchase of various types of gasket, also pay attention to check the geometric size and shape.
