自上料混凝土攪拌車門窗以及焊縫處其實都會粘貼封膠條,這也是為了確保密封性所采取的操作,不然這些縫隙處就會容易被外面的風(fēng)沙所塞滿,從而引起腐蝕等一系列不良現(xiàn)象。今天小編要在這里跟大家分享一下關(guān)于自動上料混凝土攪拌車密封膠條的日常維護。
In fact, sealing strips will be pasted on the doors, windows and welds of the self feeding concrete mixer, which is also the operation taken to ensure the tightness. Otherwise, these gaps will be easily filled with wind and sand outside, resulting in a series of adverse phenomena such as corrosion. Today, Xiaobian will share with you about the daily maintenance of sealant strip of automatic feeding concrete mixer.
1、檢查混凝土攪拌車密封條有無大的裂紋,有無斷裂。如果密封條斷裂了,可以使用粘結(jié)劑進行修補。特別是使用密封條專用粘結(jié)劑,很容易就能把大的裂紋條補好。當(dāng)然,如果密封條損傷嚴(yán)重,或老化程度較大,好還是更換上新密封條省事。
1. Check whether the sealing strip of concrete mixer truck has large cracks and fractures. If the sealing strip breaks, it can be repaired with adhesive. In particular, the use of special adhesive for sealing strip can easily repair the large crack strip. Of course, if the seal is seriously damaged or aging, it is better to replace it with a new seal.
2、司機在使用混凝土攪拌車洗滌劑進行清洗門窗密封膠條之后,好涂覆一層高透性的保護劑,這樣既能防止密封條老化又能很大地提高密封條的密封性。除此之外,密封條的縫隙之間很容易塞滿沙塵,從而引發(fā)銹蝕。為此,應(yīng)該用刷子把沙塵等清干凈。
2. After cleaning the door and window sealant strip with concrete mixer detergent, the driver shall apply a layer of high permeability protective agent, which can not only prevent the aging of the sealing strip, but also greatly improve the sealing performance of the sealing strip. In addition, the gaps between the sealing strips are easily filled with sand and dust, resulting in corrosion. Therefore, the sand and dust should be cleaned with a brush.
3、在更換整個車身時,應(yīng)在焊縫的搭接部分涂一層密封膠,膠層厚度應(yīng)約為1mm,并且膠層不得有虛粘、氣泡等缺陷。在整個地板下表面和前輪罩下表面應(yīng)涂3mm-4mm的彈性涂層及防腐涂層。這些措施不僅可以大大增強整車的密封性和減慢車身的銹蝕速度,而且還可以大大提高乘坐適性。
3. When replacing the whole vehicle body, a layer of sealant shall be applied to the overlapping part of the weld, the thickness of the adhesive layer shall be about 1mm, and the adhesive layer shall be free of defects such as virtual adhesion and bubbles. 3mm-4mm elastic coating and anti-corrosion coating shall be applied on the whole lower surface of the floor and the lower surface of the front wheel housing. These measures can not only greatly enhance the tightness of the whole vehicle and slow down the corrosion speed of the body, but also greatly improve the ride comfort.
4、車門與車身的密封是一個比較困難的部位,密封要求比較嚴(yán),應(yīng)密封的部分比較長,各密封部位的斷面形狀不盡相同,而且車門啟閉頻繁。在混凝土攪拌車上常設(shè)置3道,4道密封,安裝前支柱及車頂側(cè)橫梁部位的四重密封的構(gòu)造。這種多道密封一般都布置在前門縫里,除具有密封功能外,還有汽車隔音降噪的作用。
4. The sealing of door and vehicle body is a difficult part. The sealing requirements are strict. The part to be sealed is relatively long. The section shapes of each sealing part are different, and the door is opened and closed frequently. Three and four seals are often set on the concrete mixer, and the structure of four seals at the front pillar and roof side beam is installed. This multi-channel seal is generally arranged in the front door seam. In addition to the sealing function, it also has the function of automobile sound insulation and noise reduction.
5、在車窗玻璃損壞后,司機在換用玻璃時,要檢查密封條有無損傷。由于車窗經(jīng)過修理后往往回復(fù)不到原來的形狀,因此,這時除了要保證能輕松拉動或升降車窗玻璃外,還要注意車窗玻璃四周的密封性。如果玻璃同玻璃槽口的縫隙不均,橡膠條與玻璃、玻璃槽接觸不良,司機可以用手能輕易地將密封條拉脫。
5. After the window glass is damaged, the driver shall check whether the sealing strip is damaged when changing the glass. Because the window can not return to its original shape after repair, in addition to ensuring that the window can be easily pulled or lifted, pay attention to the sealing around the window. If the gap between the glass and the glass slot is uneven, and the rubber strip has poor contact with the glass and glass slot, the driver can easily pull off the sealing strip by hand.
6、司機在換車頂時,應(yīng)先在車頂周邊壓合處涂一層導(dǎo)電密封膠,待焊好后再在流水槽內(nèi)及接縫處遍涂折邊膠,這不但有助于車身的密封,更可防止車身因翻邊焊縫處積水而產(chǎn)生早期銹蝕。
6. When changing the roof, the driver should first apply a layer of conductive sealant at the press joint around the roof, and then apply the folding adhesive in the gutter and the joint after welding, which not only helps to seal the body, but also prevents the body from early corrosion due to ponding at the flanging weld.
7、混凝土攪拌車天窗是大多數(shù)家用轎車的基本配置。當(dāng)汽車天窗打開時,橡膠密封條軌道暴露在空氣中,難免堆積粉塵,甚跑進小沙礫。長時間使用可能導(dǎo)致天窗因磨損而變形,并堵塞排水孔。所以定期清理軌道,為軌道涂抹潤滑油十分重要。
7. The skylight of concrete mixer truck is the basic configuration of most family cars. When the car sunroof is opened, the rubber sealing strip track is exposed to the air, which will inevitably accumulate dust and even run into small gravel. Prolonged use may cause the sunroof to deform due to wear and block the drain hole. Therefore, it is very important to clean the track regularly and apply lubricating oil to the track.
混凝土攪拌車密封膠條雖是車身內(nèi)的小部件,但是它能保證開關(guān)車門沉穩(wěn)厚重,還能使車內(nèi)避風(fēng)雨、防塵、隔熱、隔音,對門窗交接的邊緣起到裝飾的效果。當(dāng)車身受到振動與扭曲時,密封條還起到緩沖、吸震、保護玻璃的作用。因此,混凝土攪拌車保養(yǎng)無小事,任何一個環(huán)節(jié)都不容忽視。
Although the sealant strip of concrete mixer truck is a small part in the car body, it can ensure the stability and massiness of opening and closing the door, and can also make the car avoid wind and rain, dust, heat and sound insulation, and play a decorative effect on the edges of door and window joints. When the vehicle body is vibrated and twisted, the sealing strip also plays the role of cushioning, shock absorption and glass protection. Therefore, there is no trivial matter in the maintenance of concrete mixer, and any link can not be ignored.
