一、首要應當維護保養自動上料攪拌罐儲罐,每一次運完混凝土后及進清潔罐,要了解混凝土是非常容易和鋼材粘接在一塊的。
1、 First of all, the tank of automatic feeding mixing tank should be maintained. After each concrete transportation and entering the cleaning tank, we should understand that the concrete is very easy to bond with the steel.
二、放料的均勻性問題是自動上料攪拌罐的一個關鍵指標值之一,它直接干擾著施工質量。在運送混凝土時,攪勻筒轉速比應控制在2~5r/min,在運送間距較長也許 混凝土的塌落度比較大時,放料前要先將攪勻筒迅速移動5~10圈,使里面的混凝土能充分攪勻,那樣放料的均勻性便會進一步提高。若中途混凝缺水,到工地應兌水調節,并充分攪勻,盡管這類環境應只要制止,可是那樣會使混凝土的品質無法得到保證。有的客戶在運用時不注意控制在運送過程中的轉速比,過快會增.大燃油的損耗,過小則會導致混凝土離析。因而應嚴苛根據要求來控制攪勻筒的轉速比,以提升混凝土運送品質。
2、 It is one of the key factors that directly interfere with the quality of the mixing tank. When transporting concrete, the rotation speed ratio of the mixing cylinder should be controlled at 2 ~ 5R / min. when the transportation distance is long or the slump of concrete is large, the mixing cylinder should be moved rapidly for 5 ~ 10 circles before discharging, so that the concrete inside can be fully mixed, and the uniformity of discharging will be further improved. If there is a shortage of water in the process of concreting, the water should be mixed to the construction site for adjustment and full mixing. Although this kind of environment should be stopped, the quality of concrete can not be guaranteed. Some customers do not pay attention to control the speed ratio in the transportation process, too fast will increase the fuel consumption, too small will lead to concrete segregation. Therefore, it is necessary to strictly control the speed ratio of the mixing cylinder according to the requirements, so as to improve the quality of concrete transportation.
三、凝土較大限定不可以高出儲罐的較大方量,是因為混凝土強度等級區別它的密度也區別,高強度混凝土一般密度也大,一樣的容積,裝多了對車不好。輸送混凝土的容積、品質及坍落度應契合車輛運用使用說明書中的要求,實時加注潤滑油。
3、 Because of the difference of concrete strength grade, the density of concrete is also different. The density of high-strength concrete is generally large, and the same volume is not good for the car. The volume, quality and slump of the transported concrete shall meet the requirements of the vehicle operation manual, and the lubricating oil shall be added in real time.
四、露天停放過的自動上料攪拌罐,裝料前要先將攪勻筒以放料偏向旋轉,把水泥罐內的積水放掉,確保運送混凝土的品質。
4、 For the automatic feeding mixing tank which has been parked in the open air, before loading, the mixing cylinder should be rotated to discharge the water in the cement tank to ensure the quality of concrete.
