攪拌車底部在車送過程中被劃傷或打結

來源:http://www.xiaoplaoshi.cn 瀏覽:0發表時間:2022-07-06
混凝土自上料攪拌車的應用地提高了日常施工的施工效率,但有時在車送過程中可能會出現其他現象,例如,由于各種原因可能導致打底或打結。 如何解決這些問題? 現在讓我們具體介紹它們。
The application of concrete self loading mixer improves the construction efficiency of daily construction, but sometimes other phenomena may occur in the process of vehicle delivery, such as bottoming or knotting due to various reasons. How to solve these problems? Now let's introduce them in detail.
在攪拌車的運行過程中,由于施工條件或天氣原因,可能會導致混凝土自上料攪拌車底部在車送過程中被劃傷或打結。這種現象有很多原因。 簡單來說,主要有以下幾個原因:
During the operation of the mixer truck, due to construction conditions or weather reasons, the bottom of the concrete mixer truck may be scratched or knotted during the delivery process. There are many reasons for this phenomenon. In short, there are several reasons:
1。商業污染的混凝土容易刮傷或打結(粘鍋),所以要注意生產過程中的出血量。
1。 Commercial contaminated concrete is easy to scratch or knot (stick to the pot), so pay attention to the amount of bleeding in the production process.
2。含有大量水泥的商品混凝土易于打底。 因此,商品混凝土水泥的生產也是一個須注意的問題。
2。 Commercial concrete containing a lot of cement is easy to be primed. Therefore, the production of commercial concrete cement is also a problem that should be paid attention to.
3。大量商品混凝土外加劑的商品混凝土易于打底,因此在制作商品混凝土時遵循的規則非常重要。
3。 Commercial concrete with a large number of commercial concrete admixtures is easy to be primed, so the rules to be followed in the production of commercial concrete are very important.
商品混凝土外加劑具有較高的減水率和較高的出血率。 保水性差,增稠和夾帶不良的商品混凝土易于打底或打結。 應該注意這些。由于上述原因,為了避免混凝土自上料攪拌車車送商品混凝土具有底部或結的現象,可以采用以下解決方案:
Commercial concrete admixtures have higher water reduction rate and higher bleeding rate. Commercial concrete with poor water retention, thickening and entrainment is easy to be bottomed or knotted. You should pay attention to these. Due to the above reasons, the following solutions can be adopted to avoid the bottom or knot of commercial concrete delivered from the loading mixer truck:
混凝土自上料攪拌車廠家
1。減少每個單位的用水量。
1。 Reduce water consumption per unit.
2。增加砂率。
2。 Increase sand ratio.
3。加入適量的混合物,如粉煤灰,以減少水泥的用量。
3。 Add an appropriate amount of mixture, such as fly ash, to reduce the amount of cement.
4。減少商品混凝土外加劑的用量。
4。 Reduce the dosage of commercial concrete admixtures.
5。增加商品混凝土外加劑的通風,增稠和保水功能。
5。 Increase the ventilation, thickening and water retention functions of commercial concrete admixtures.
此外混凝土自上料攪拌車廠家要提醒大家,在攪拌車車的液壓系統中,A和B端口分別連接到兩個泵送缸的入口和出口腔室,并且主泵交替地將來自A和B端口的高壓油輸送到兩個泵送泵。 泵車泵缸有高壓油進入桿腔,當活塞桿縮回時,右泵缸沒有桿腔壓力油。 高壓油管在沒有桿腔的情況下進入左泵缸,并驅動左泵缸活塞桿延伸。
In addition, the concrete self loading mixer truck manufacturer should remind everyone that in the hydraulic system of the mixer truck, ports a and B are respectively connected to the inlet and outlet chambers of the two pumping cylinders, and the main pump alternately transmits the high-pressure oil from ports a and B to the two pumping pumps. There is high-pressure oil in the pump cylinder of the pump truck entering the rod cavity. When the piston rod is retracted, there is no pressure oil in the rod cavity in the right pump cylinder. The high-pressure oil pipe enters the left pump cylinder without rod cavity and drives the piston rod of the left pump cylinder to extend.
當接近開關檢測到右泵缸活塞桿就位時,控制系統發出換向信號。 在主泵接收到反向信號之后,左泵送缸連接有桿室壓力油以縮回左泵缸活塞桿。 左泵缸沒有桿腔壓力油,通過高壓油管進入右泵缸無桿室,驅動右泵缸活塞桿伸出。 兩個泵送缸交替運行以完成攪拌車送工作。
When the proximity switch detects that the piston rod of the right pump cylinder is in place, the control system sends a reversing signal. After the main pump receives the reverse signal, the left pump cylinder is connected with rod chamber pressure oil to retract the piston rod of the left pump cylinder. There is no pressure oil in the rod chamber of the left pump cylinder, which enters the rod free chamber of the right pump cylinder through the high-pressure oil pipe to drive the piston rod of the right pump cylinder to extend. The two pumping cylinders operate alternately to complete the delivery of the mixer truck.
