The price should be reasonable
在滿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(jī)構(gòu)設(shè)計(jì)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 discharge of concrete storage tank should be thorough
這些混凝土攪拌車使用中經(jīng)常遇到的問題也須考慮到。比如若卸料不完全，留在罐內(nèi)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。
These problems often encountered in the use of concrete mixer should also be considered. For example, if the discharge is not complete, more and more concrete will be left in the tank, which will reduce the capacity of the tank and make the cleaning very difficult.
售后服務(wù)要好
Good after sales service
混凝土攪拌車是一種專用重型車輛，保有量少，配件來(lái)源少，與一般通用汽車相比，對(duì)廠家的售后服務(wù)依賴性較大，因此，廠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。
Concrete mixer is a kind of special heavy-duty vehicle, with less ownership and less source 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)，混凝土攪拌車的裝載量越大，運(yùn)輸效率越高，但這也會(huì)導(dǎo)致車輛購(gòu)置成本直線上升和通過性下降。裝載量為8～9m38×4底盤的混凝土攪拌運(yùn)輸車要比裝載量為6～7m36×4底盤的價(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，大車尤其是半掛車行動(dòng)不便的問題須充分考慮到。因此，確定車輛的裝載量時(shí)定要綜合考慮各方面的因素，不可顧此失彼。
Theoretically, the larger the loading capacity of concrete mixer, the higher the transportation efficiency, but it will also lead to a sharp rise in vehicle purchase cost and a decline in trafficability. The loading capacity is 8-9m38 × The specific loading capacity of concrete mixer truck with 4 chassis is 6-7m36 × 4. The price of chassis is 30% - 40%; At the same time, the construction site is generally narrow and small, the road condition of temporary construction road is very poor, and the mobility of large vehicles, especially semi-trailer, should be fully considered. Therefore, when determining the loading capacity of the vehicle, we must take all factors into consideration.
使用要可靠
Use it reliably
混凝土裝入車內(nèi)以后，要求在2h或更短的時(shí)間內(nèi)卸到工作面上，在此期間須不停地?cái)嚢?；如果在?guī)定時(shí)間內(nèi)不能運(yùn)到工地或因各種原因停止攪拌，車內(nèi)混凝土就會(huì)報(bào)廢，嚴(yán)重的會(huì)導(dǎo)致混凝土凝固在車內(nèi)，造成攪拌運(yùn)輸車報(bào)廢。這對(duì)攪拌運(yùn)輸車的可靠性提出了嚴(yán)格的要求，不允許攪拌運(yùn)輸車在工作時(shí)發(fā)生停機(jī)的故障，因此混凝土攪拌車選型要考慮的就是車輛須十分可靠，關(guān)鍵部位如發(fā)動(dòng)機(jī)和傳動(dòng)驅(qū)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 truck, it is required to be unloaded to the working face within 2 hours or less, during which time it must be continuously mixed; If the concrete cannot 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. In serious cases, the concrete will solidify in the truck and the truck will be scrapped. This puts forward strict requirements for 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 concrete mixer truck is that the truck must be very reliable. The lower the possibility of failure of key parts such as engine and transmission drive device, the better.
混凝土貯罐及進(jìn)、出料口要耐磨
The concrete storage tank, inlet and outlet shall be wear resistant
沙和礫石是混凝土的主要組成成分。它們使混凝土攪拌車混凝土貯罐及進(jìn)、出料口在工作時(shí)磨損嚴(yán)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(nèi)的螺旋葉片壽命只有3萬(wàn)～4萬(wàn)m3。國(guó)產(chǎn)混凝土貯罐一般由高強(qiáng)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。由此可知，采用材料不同其工作壽命則大不相同。
Sand and gravel are the main components of concrete. They make the concrete storage tank, inlet and outlet of concrete mixer wear seriously during working. In general, the service life of concrete tanks made of low alloy steel is 50000-80000 m3, and the service life of spiral blades in concrete tanks 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 special wear-resistant steel and reinforced with wear-resistant materials in the easily worn parts, so their service life can be twice as long as that made of low alloy steel. It can be seen that different materials have different working life.
