自拌混凝土攪拌車(chē)。稱(chēng)量是混凝土攪拌站中很重要的一個(gè)環(huán)節,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(jìn)行稱(chēng)量,因此,混凝土攪拌站中的稱(chēng)量系統需要有以下要求:
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(chē)。擴大溫度和濕度范圍需要?;炷翑嚢枵镜墓ぷ鳝h(huán)境與一般的商貿計量的電子秤不同,一般的商貿計量的電子秤的工作環(huán)境一般相對穩定,而移動(dòng)式混凝土攪拌站中荷重傳感器的應力環(huán)境十分復雜,運行條件相對更加惡劣,有更大的隨機性?;炷翑嚢枵就ǔJ锹短彀惭b,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(chē)。耐腐蝕性要求更高?;炷翑嚢枵镜墓ぷ鳝h(huán)境十分惡劣,不僅溫度和濕度都有很大的浮動(dòng)空間,還存在一定的腐蝕性?;炷猎谏a(chǎn)過(guò)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(chēng)量過(guò)程中會(huì )產(chǎn)生粉塵。這些粉塵有一部分會(huì )附著(zhù)在稱(chēng)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(chē)。需要進(jìn)行一些特殊設計?;炷翑嚢枵疽话惆惭b在施工現場(chǎng),工作人員的工作素質(zhì)也會(huì )影響稱(chēng)重系統的使用情況。工地上大量使用臨時(shí)工,其中相當多的臨時(shí)工文化水平較低,缺少必要的技能。在設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(guò)載等情況。傳感器要在這樣的環(huán)境條件下長(cháng)期可靠的運行,是要進(jìn)行一些特殊設計的。
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.
