Zhongke Jufeng concrete mixer truck has been very common in our daily life. Small concrete mixer truck will also have problems in the process of use. Sometimes it is necessary to replace accessories. Any equipment has its service life cycle. Especially for special vehicles like concrete mixer, its accessories have service life, besides being diligent in maintenance Besides, it depends on the quality itself, so once the parts of the concrete mixer truck are damaged and need to be replaced, how can we choose qualified accessories? People who don't know the trade are likely to buy fake and shoddy products when they buy mixer accessories. Today, I'll tell you about the problems that should be paid attention to when purchasing mixer accessories.

一、小型混凝土攪拌車配件選購時需要注意以下問題

1、 Attention should be paid to the following problems when purchasing small concrete mixer accessories

1、看幾何尺寸有無變形有些小型混凝土攪拌車配件零件因制造、運輸、存放不當，易產生變形。檢查時，可將軸類零件沿玻璃板滾動一圈，看零件與玻璃板貼合處有無漏光來判斷是否彎曲；選購混凝土攪拌車離合器從動盤鋼片或摩擦片時，可將鋼片、摩擦片舉在眼前觀察其是否翹曲；在選購油封時，帶骨架的油封端面應呈正圓形，能與平板玻璃貼合無撓曲；無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。在選購各類襯墊時，也應注意檢查幾何尺寸及形狀。

1. Some parts of small concrete mixer truck parts are easy to deform due to improper manufacturing, transportation and storage. During the inspection, the shaft parts can be rolled around the glass plate to see if there is light leakage at the joint between the parts and the glass plate to judge whether it is bent; when purchasing the steel plate or friction plate of clutch driven plate of concrete mixer truck, hold the steel plate and friction plate in front of your eyes to observe whether it is warped; when purchasing the oil seal, the oil seal end surface with skeleton should be round, which can fit with the flat glass without bending; The outer edge of the frameless oil seal should be straight and deformed by hand. It should be able to return to its original state after releasing it. In the purchase of various types of pads, should also pay attention to check the geometric size and shape.
              

2、看零件表面有無銹蝕

2. Check whether there is rust on the surface of parts

合格的小型混凝土攪拌車零配件表面，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。選購時應注意檢查，若發(fā)現(xiàn)混凝土攪拌車零件有銹蝕斑點、霉變斑點或橡膠件龜裂、失去彈性，或軸頸表面有明顯車刀紋路，應予調換。

Qualified small concrete mixer parts surface, both have a certain precision and smooth finish, the more important parts, the higher the accuracy, the more stringent the anti rust and anti-corrosion packaging. Pay attention to the inspection when purchasing. If the parts of the concrete mixer have rust spots, mildew spots, or rubber parts are cracked and lose elasticity, or there are obvious turning tool lines on the journal surface, they should be replaced.

3、看轉動部件是否靈活

3. See if the rotating parts are flexible

選購機油泵等轉動部件總成時，用手轉動泵軸，應感到靈活無卡滯；選購混凝土攪拌車滾動軸承時，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，然后逐漸停轉。若轉動部件轉動不靈，說明內部銹蝕或產生變形，不要購買。

When purchasing the oil pump and other rotating parts assembly, rotate the pump shaft by hand, which should be flexible and free of jamming; when purchasing the rolling bearing of concrete mixer truck, support the inner bearing ring with one hand and rotate the outer ring with the other hand. The outer ring should be able to rotate quickly and freely, and then stop rotating gradually. If the rotating parts do not work well, it means that the internal corrosion or deformation, do not buy.

4、看結合部位是否平整

4. Check whether the joint is smooth

混凝土攪拌車零配件在搬運、存放過程中，由于振動、磕碰，常會在結合部位產生毛刺、壓痕、破損或裂紋，影響混凝土攪拌車零件的使用。選購時應注意檢查。

In the process of transportation and storage, due to vibration and collision, burr, indentation, damage or crack often occur in the joint parts of concrete mixer truck, which affects the use of concrete mixer parts. Pay attention to check when purchasing.

5、看防護表層是否完好

5. Check whether the protective surface is in good condition

大多數(shù)小型混凝土攪拌車零件在出廠時都涂有防護層。如活塞銷、軸瓦用石蠟保護；活塞環(huán)、缸套表面涂防銹油并用包裝紙包裹；氣門、活塞等浸防銹油后用塑料袋封裝。選購時若發(fā)現(xiàn)密封套破損、包裝紙丟失、防銹油或石蠟流失，應予退換。

Most of the small concrete mixer parts are coated with protective coating when leaving the factory. For example, the piston pin and bearing bush are protected by paraffin; the surface of piston ring and cylinder liner is coated with antirust oil and wrapped with wrapping paper; the valves and pistons are sealed with plastic bags after being immersed in antirust oil. If the seal sleeve is damaged, the packing paper is lost, antirust oil or paraffin is lost, it should be returned and replaced.

6、看膠接混凝土攪拌車零件有無松動

6. Check whether the parts of bonding concrete mixer are loose

由兩個或兩個以上零件組合成的配件，零件之間是通過壓裝、膠接或焊接的，它們之間不允許有松動現(xiàn)象，如混凝土攪拌車油泵柱塞與調節(jié)臂是通過壓裝組合的；離合器從動輪與鋼片是鉚接結合的，摩擦片與鋼片是鉚接或膠接的；紙質濾清器濾芯骨架與濾紙是膠接而成的；混凝土攪拌車電器設備的線頭是焊接而成的。選購時若發(fā)現(xiàn)有松動，應予調換。

For the accessories composed of two or more parts, the parts are pressed, glued or welded, and there is no looseness between them. For example, the plunger of the oil pump of the concrete mixer truck and the adjusting arm are assembled by pressing; the driven wheel of the clutch is riveted with the steel plate; the friction plate and the steel plate are riveted or glued; the paper filter element framework is glued to the filter paper The wire ends of the electrical equipment of the concrete mixer are welded. If any looseness is found during purchase, it should be replaced.

7、要看商標標識是否齊全

7. First of all, we should see whether the trademark is complete

正規(guī)小型混凝土攪拌車配件產品的外包裝質量好，包裝盒上字跡清晰，套印色彩鮮明。包裝盒、袋上，應標有產品名稱、規(guī)格型號、數(shù)量、注冊商標、廠名廠址及電話號碼等等，有的廠家還在配件上打出自己的標記。一些重要混凝土攪拌車部件如發(fā)電機、分電器、噴油泵等，還配有使用說明書、合格證和檢驗員章，以指導用戶正確使用維護。選購時應仔細認清，以防買了假冒偽劣產品。

Regular small-scale concrete mixer accessories products have good external packaging quality, clear handwriting on the packaging box and bright overprint color. The packing box and bag should be marked with the product name, specification and model, quantity, registered trademark, factory name, address and telephone number, etc. some manufacturers also make their own marks on the accessories. Some important components of concrete mixer such as generator, distributor, fuel pump, etc. are also equipped with instruction manual, certificate and inspector's seal to guide users to use and maintain correctly. Purchase should be carefully recognized, in order to prevent the purchase of fake and shoddy products.

8、看小型混凝土攪拌車配件總成部件有無缺件正規(guī)的總成部件必須齊全完好，才能保證順利裝配和正常運行。一些總成部件上的個別小零件若漏裝，將使總成部件無法工作甚報廢。

8. To see whether there is a lack of small concrete mixer parts assembly parts, regular assembly parts must be complete and intact, in order to ensure smooth assembly and normal operation. If some small parts on some assembly parts are missing, the assembly parts will not work or even be scrapped.

小型混凝土攪拌車上的零配件有很多，大家在購買之前一定要了解其性能、特點，這樣在購買的時候才能買到貨真價實的好配件。

There are a lot of spare parts on the small concrete mixer, we must understand its performance and characteristics before purchasing, so that we can buy real good accessories when we buy.
