系統(tǒng)工作原理

Working principle of the system

FMCS 系列變頻同步控制系統(tǒng)是一種閉環(huán)控制系統(tǒng)，是基于變頻控制技術(shù) (VFDM) 與傳感器技術(shù)來(lái)控制千斤頂升降及準(zhǔn)確定位?？刂七^(guò)程無(wú)需考慮重物的中心分布，適用于對(duì)大型、重載結(jié)構(gòu)進(jìn)行整體頂升作業(yè)。

FMCS series variable frequency synchronization control system is a closed-loop control system, which is based on the variable frequency control technology (VFDM) and sensor technology to control the lifting and accurate positioning of the jack.The control process does not need to consider the center distribution of heavy objects, which is suitable for the overall lifting operation of large and heavy load structures.

VFDM 技術(shù)實(shí)現(xiàn)了真正意義上的連續(xù)流量調(diào)節(jié)，通過(guò)連續(xù)改變電機(jī)的轉(zhuǎn)速來(lái)調(diào)節(jié)流量的大小。因此變頻控制技術(shù)在平穩(wěn)性和可靠性方面要高于同類型的其他系統(tǒng)。

VFDM technology realizes continuous flow regulation in real sense, which can adjust the flow rate by continuously changing the speed of the motor.Therefore, frequency conversion control technology is higher in stability and reliability than other systems of the same type.

每個(gè)控制點(diǎn)兼有壓力和位移雙重控制系統(tǒng) ，可實(shí)現(xiàn)同步升降、同步頂推、重載稱重、等比例升降、姿態(tài)調(diào)整等多種功能。基于PLC 控制的同步頂升系統(tǒng)減少了重量分布不均和不同頂升點(diǎn)間負(fù)載轉(zhuǎn)移造成的折彎，扭曲和傾斜的危險(xiǎn)。

Each control point has dual pressure and displacement control system, which can realize synchronous lifting, synchronous pushing, heavy load weighing, etc.The synchronous jacking system based on PLC reduces the risk of bending, twisting and slanting caused by uneven weight distribution and load transfer between different jacking points.

特點(diǎn)：

采用雙泵系統(tǒng)，實(shí)現(xiàn)了高速置零，平穩(wěn)頂升的功能。

The double pump system is adopted to achieve the function of high speed zero setting and smooth lifting.

完全計(jì)算機(jī)控制，頂升過(guò)程無(wú)需人工干涉，系統(tǒng)自動(dòng)檢測(cè)頂升狀態(tài)并能根據(jù)頂升情況給出。

Complete computer control, lifting process without manual interference, the system automatically detects the lifting status and can be given according to the lifting situation;

同步控制精度可以達(dá)到 0.1mm，同步頂升和同步下降都完全可控。

The accuracy of synchronous control can reach 0.1mm, and synchronous jacking and synchronous descent are completely controllable.

每個(gè)控制點(diǎn)油路相對(duì)獨(dú)立，系統(tǒng)壓力可以單獨(dú)調(diào)節(jié)互不干涉。

Each control point is relatively independent and the system pressure can be adjusted independently of each other.

系統(tǒng)主要部件均選用知名國(guó)際品牌，密封件全部采用進(jìn)口密封。

The main components of the system are famous international brands, and all seals are imported sealed.

適用性比較廣泛，可配套使用單作用千斤頂或者雙作用千斤頂。

It has wide applicability and can be matched with single acting jack or double acting Jack.

系統(tǒng)使用方便 , 液壓管路與液壓千斤頂以及液壓泵組連接全部采用快插式接頭。

The system is easy to use, and the connection between hydraulic pipeline and hydraulic jack and hydraulic pump group is all made of quick plug-in joint.

根據(jù)使用工況，可選用接入位移傳感器和壓力傳感器，對(duì)系統(tǒng)工況進(jìn)行實(shí)時(shí)監(jiān)控。

According to the working condition, the displacement sensor and pressure sensor can be selected to monitor the working condition of the system in real time.
