自拌混凝土攪拌車。稱量是混凝土攪拌站中很重要的一個環(huán)節(jié),為了保證生產(chǎn)出高質(zhì)量的混凝土,需要對混凝土原材料進行稱量,因此,混凝土攪拌站中的稱量系統(tǒng)需要有以下要求:
Self mixing concrete mixer. Weighing is a very important link in the concrete mixing plant. In order to ensure the production of high-quality concrete, it is necessary to weigh the concrete raw materials. Therefore, the weighing system in the concrete mixing plant needs the following requirements:
自拌混凝土攪拌車。擴大溫度和濕度范圍需要?;炷翑嚢枵镜墓ぷ鳝h(huán)境與一般的商貿(mào)計量的電子秤不同,一般的商貿(mào)計量的電子秤的工作環(huán)境一般相對穩(wěn)定,而移動式混凝土攪拌站中荷重傳感器的應(yīng)力環(huán)境十分復(fù)雜,運行條件相對更加惡劣,有更大的隨機性。混凝土攪拌站通常是露天安裝,傳感器經(jīng)常遭受日曬雨淋,溫度處于很大的變換狀態(tài)。
Self mixing concrete mixer. It is necessary to expand the temperature and humidity range. The working environment of the concrete mixing plant is different from that of the general commercial scale. The working environment of the general commercial scale is generally relatively stable, while the stress environment of the load sensor in the mobile concrete mixing plant is very complex, the operating conditions are relatively worse and have greater randomness. The concrete mixing plant is usually installed in the open air. The sensor is often exposed to the sun and rain, and the temperature is in a great change state.
自拌混凝土攪拌車。耐腐蝕性要求更高。混凝土攪拌站的工作環(huán)境十分惡劣,不僅溫度和濕度都有很大的浮動空間,還存在一定的腐蝕性?;炷猎谏a(chǎn)過程中需要大量的水泥、煤粉灰以及適量的外加劑,這些粉狀物在輸送和稱量過程中會產(chǎn)生粉塵。這些粉塵有一部分會附著在稱重傳感器表面。在粉塵和水氣的共同作用下,傳感器將受到較為嚴重的腐蝕。
Self mixing concrete mixer. Higher corrosion resistance requirements. The working environment of concrete mixing plant is very bad. There is not only a large floating space for temperature and humidity, but also a certain corrosivity. A large amount of cement, pulverized coal ash and an appropriate amount of admixture are required in the production of concrete. These powders will produce dust in the process of transportation and weighing. Some of this dust will adhere to the surface of the load cell. Under the combined action of dust and water vapor, the sensor will be seriously corroded.
自拌混凝土攪拌車。需要進行一些特殊設(shè)計?;炷翑嚢枵疽话惆惭b在施工現(xiàn)場,工作人員的工作素質(zhì)也會影響稱重系統(tǒng)的使用情況。工地上大量使用臨時工,其中相當多的臨時工文化水平較低,缺少必要的技能。在設(shè)備的維修和清洗等工作中,很有可能發(fā)生傳感器受到高壓水的濺射,誤操作引起過載等情況。傳感器要在這樣的環(huán)境條件下長期可靠的運行,是要進行一些特殊設(shè)計的。
Self mixing concrete mixer. Some special design is required. The concrete mixing plant is generally installed on the construction site, and the working quality of the staff will also affect the use of the weighing system. Temporary workers are widely used on the construction site, and a considerable number of them have low educational level and lack necessary skills. In the maintenance and cleaning of equipment, it is likely that the sensor will be sputtered by high-pressure water and overload will be caused by misoperation. The sensor needs some special design to operate reliably for a long time under such environmental conditions.
