The price should be reasonable

在滿(mǎn)足上述要求的前提下再考慮價(jià)格因素。

On the premise of meeting the above requirements, the price factor will be considered.

機構設計合理，操作方便，混凝土貯罐卸料要徹底

The mechanism design is reasonable, the operation is convenient, and the unloading of concrete tank should be thorough

這些全自動(dòng)混凝土攪拌車(chē)使用中經(jīng)常遇到的問(wèn)題也須考慮到。比如若卸料不完全，留在罐內的混凝土就會(huì )越積越多，使貯罐容量減小，并且清理十分困難。

The problems often encountered in the use of these full-automatic concrete mixers should also be considered. For example, if the unloading is not complete, the concrete left in the tank will accumulate more and more, which will reduce the tank capacity and is very difficult to clean.

售后服務(wù)要好

After sales service was good

全自動(dòng)混凝土攪拌車(chē)是一種專(zhuān)用重型車(chē)輛，保有量少，配件來(lái)源少，與一般通用汽車(chē)相比，對廠(chǎng)家的售后服務(wù)依賴(lài)性較大，因此，廠(chǎng)家是否能提供方便快捷可靠的售后服務(wù)，是選型中須考慮的重要因素。

Full automatic concrete mixer truck is a special heavy vehicle, which has a small amount of possession and less sources of accessories. Compared with general motors, it is more dependent on the manufacturer's after-sales service. Therefore, whether the manufacturer can provide convenient, fast and reliable after-sales service is an important factor to be considered in the selection.

裝載量要合適

The loading capacity should be appropriate

理論上說(shuō)，全自動(dòng)混凝土攪拌車(chē)的裝載量越大，運輸效率越高，但這也會(huì )導致車(chē)輛購置成本直線(xiàn)上升和通過(guò)性下降。裝載量為8～9m38×4底盤(pán)的混凝土攪拌運輸車(chē)要比裝載量為6～7m36×4底盤(pán)的價(jià)格貴30%～40%；同時(shí)，建筑工地一般地域狹小，臨時(shí)施工道路路況很差，大車(chē)尤其是半掛車(chē)行動(dòng)不便的問(wèn)題須充分考慮到。因此，確定車(chē)輛的裝載量時(shí)定要綜合考慮各方面的因素，不可顧此失彼。

In theory, the greater the loading capacity of the full-automatic concrete mixer truck, the higher the transportation efficiency, but this will also lead to a straight-line increase in vehicle purchase cost and a decline in trafficability. The price of concrete mixer truck with 8-9m38 × 4 chassis is 30% - 40% more expensive than that of 6-7m36 × 4 chassis. Meanwhile, the construction site is generally narrow, and the road condition of temporary construction road is very poor. The problem of inconvenient movement of large vehicles, especially semi-trailer, should be fully considered. Therefore, when determining the loading capacity of the vehicle, we must consider all factors comprehensively, and we can't neglect one and lose the other.

使用要可靠

Use it reliably

混凝土裝入車(chē)內以后，要求在2h或更短的時(shí)間內卸到工作面上，在此期間須不停地攪拌；如果在規定時(shí)間內不能運到工地或因各種原因停止攪拌，車(chē)內混凝土就會(huì )報廢，嚴重的會(huì )導致混凝土凝固在車(chē)內，造成攪拌運輸車(chē)報廢。這對攪拌運輸車(chē)的可靠性提出了嚴格的要求，不允許攪拌運輸車(chē)在工作時(shí)發(fā)生停機的故障，因此全自動(dòng)混凝土攪拌車(chē)選型要考慮的就是車(chē)輛須十分可靠，關(guān)鍵部位如發(fā)動(dòng)機和傳動(dòng)驅動(dòng)裝置發(fā)生故障的可能性要越低越好。

After the concrete is loaded into the vehicle, it is required to unload it to the working face within 2 hours or less, during which the mixing must be kept on; if the concrete can not be transported to the construction site within the specified time or the mixing is stopped for various reasons, the concrete in the truck will be scrapped, which will cause the concrete to solidify in the vehicle, resulting in the scrapping of the mixing truck. This puts forward strict requirements on the reliability of the mixer truck. It is absolutely not allowed to stop the mixer truck when it is working. Therefore, the first thing to consider in the selection of automatic concrete mixer truck is that the vehicle must be very reliable, and the lower the possibility of failure of key parts such as engine and driving device, the better.

混凝土貯罐及進(jìn)、出料口要耐磨

The concrete storage tank and inlet and outlet shall be wear-resistant

沙和礫石是混凝土的主要組成成分。它們使全自動(dòng)混凝土攪拌車(chē)混凝土貯罐及進(jìn)、出料口在工作時(shí)磨損嚴重。一般情況下，采用低合金鋼制造的混凝土貯罐使用壽命為5萬(wàn)～8萬(wàn)m3，混凝土貯罐內的螺旋葉片壽命只有3萬(wàn)～4萬(wàn)m3。國產(chǎn)混凝土貯罐一般由高強度低合金鋼鋼材制成，比普通A3鋼材耐磨提高1～2倍。一些進(jìn)口混凝土貯罐采用錳硼專(zhuān)用耐磨鋼材，并且在易磨損部位鑲耐磨材料加固，因此其使用壽命比低合金鋼制造的又可提高1倍。

Sand and gravel are the main components of concrete. They make the concrete storage tank and the inlet and outlet of the full-automatic concrete mixer seriously worn during operation. In general, the service life of concrete tank made of low alloy steel is 50000-80000 m3, and the service life of spiral blade in concrete tank is only 30000-40000 m3. Domestic concrete tanks are generally made of high strength low alloy steel, which is 1-2 times more wear-resistant than ordinary A3 steel. Some imported concrete tanks are made of manganese boron wear-resistant steel, and the wear-resistant materials are inlaid in the easily worn parts. Therefore, the service life of these tanks can be doubled compared with those made of low-alloy steel.
