高精度皮帶秤的技術(shù)突破
摒棄傳統(tǒng)皮帶秤誤差理論、創(chuàng)建新的誤差理論，皮帶秤主要誤差源——皮帶張力影響基本消除
傳統(tǒng)皮帶秤誤差理論高精對皮帶秤之“內(nèi)力理論”
對一個單獨的稱重單元來說，其皮帶張力的影響和傳統(tǒng)皮帶秤裝態(tài)相同；在一個連續(xù)安裝的稱重陣列中，相鄰單元的皮帶張力影響相互抵消。即一個連續(xù)安裝的稱重陣列內(nèi)部皮帶張力影響力成為一種“內(nèi)力”，對稱重的影響為零，皮帶張力的影響于陣列的出、入口處的單元。
12托輥皮帶秤之“皮帶效應(yīng)理論”
“皮帶效應(yīng)”是指皮帶的硬度、弱性等物理特性對稱重產(chǎn)生的效應(yīng)。在皮帶張力的作用下槽形皮帶呈半剛性狀，當(dāng)支承點高度不在一個準(zhǔn)直面時，皮帶沿運行方向會產(chǎn)生波浪、其對稱重產(chǎn)生的影響稱之為“皮帶效應(yīng)”?！捌?yīng)”的影響隨皮帶的硬度、物料的流量、環(huán)境的流量、環(huán)境的溫度等因素的變化而變化。陣列式皮帶秤通過檢測、分析各單元采樣值、建立一個“皮帶效應(yīng)”影響的數(shù)學(xué)模型并進行補償修正。在“內(nèi)力理論”指導(dǎo)下，采用與常規(guī)皮帶秤截然不同的設(shè)計理念，稱重單元整體結(jié)構(gòu)十分獨特，特別適合在惡劣工況下長期工作，對提高皮帶秤的長期穩(wěn)定期穩(wěn)定性起到了關(guān)鍵作用。
單元使用一只稱重傳感器，支承兩組稱重托輥組采用獨特的高抗彎性能結(jié)構(gòu)設(shè)計結(jié)構(gòu)簡便，重量輕，現(xiàn)場安裝快捷、方便稱重托輥組采用皮帶機原有托輥組日常工作中免維護
測力式稱重傳感器
皮帶秤所用稱重傳感器為經(jīng)多方研究成功的特制專用傳感器，傳感器具有抗水平力、偏載等多項優(yōu)異性能指標(biāo)，整體性能大大提升。

The stiffness of the weighing unit is greatly reduced, the weight is reduced and the influence of the belt tension change is reduced effectively. No impact on the use of roller materials for trade settlement and the more important bulk material measurement are expert system remote diagnosis, troubleshooting, remote early diagnosis, early warning, removal of the use of accuracy up to 0.2%, truly up to 0.2 class measurement requirements, stability period of more than 6 months. It is equipped with unique tracking to avoid zero point deviation system, each sensor alone AD detection, fault judgment, super-differential culling and other functions, so that the belt scale long-term high-precision stable operation. The real realization of high precision, self-check, maintenance-free, so as to ensure the accurate measurement of belt scales. The main index of high precision belt scale Rated flow rated 30t/h -13000t/h Error in physical verification Single countless n =12;≤0.1%(initial verification);≤0.2%(in use) Number of columns n ≤12 Effective weighing section length 2L × n (L: idler spacing ） Belt Width 500-2400mm Belt speed 0.5-5m/s Belt Type TD75, DTII Communication protocol Standard Modbus Communication interface RS-485, RS-232, Ethernet Technical Breakthrough of High Precision Belt Scale Abandoning the traditional theory of belt scale error and creating a new theory of error, the main error source of belt scale is basically eliminated The "Internal Force Theory" of the Traditional Belt Scale Error Theory for a separate weighing unit, the effect of its belt tension is the same as that of the traditional belt scale loading; in a continuously mounted weighing array, the belt tension effect of the adjacent units cancels each other out. that is, the influence of the inner belt tension of a continuously mounted weighing array becomes a “internal force ”, the effect on the weighing is zero, and the influence of the belt tension is limited to the unit at the outlet, entrance of the array. The Theory of Belt Effect on 12 Roller Belt Scale “belt effect" refers to the belt hardness, weakness and other physical properties of the symmetry of the effect. Under the action of belt tension, the groove belt is semi-rigid. When the height of the supporting point is not in a quasi-surface, the belt will produce waves along the running direction, and the effect of its symmetrical weight is called "belt effect ". The influence of "belt effect" varies with the hardness of the belt, the flow rate of the material, the flow rate of the environment, the temperature of the environment and so on. The array belt scale can be compensated by detecting, analyzing the sample value of each unit, establishing a mathematical model of the influence of "belt effect ". Under the guidance of "internal force theory ", adopting the design idea which is very different from the conventional belt scale, the whole structure of weighing unit is very unique, especially suitable for long-term work under bad working conditions, which plays a key role in improving the long-term stability of the belt scale. The unit uses a weighing sensor to support the two groups of weighing rollers with a unique high bending resistance structure. The structure is simple, the weight is light, and the field installation is quick and convenient. Force weighing sensor The weighing sensor used in the belt scale is a special-made sensor successfully studied by many parties. The sensor has many excellent performance indexes, such as anti-level force and partial load, and the overall performance is greatly improved.
