The central heating system consists of three parts: heat source, heat supply network and heat user. The purpose is to keep the indoor temperature suitable and keep the building in the balance of heat gain and heat loss. Among them, the heat supply network undertakes the task of timely transferring and distributing the heat from the heat source to each heat user, which plays a bridge role in connecting the two, and is an important part of the heating system.
壓力變送器是許多工業(yè)設(shè)備中用以控制工業(yè)過程和壓力變化的重要原件。壓力變送器用于測(cè)量液體、氣體或蒸汽的液位、密度和壓力，然后將壓力信號(hào)轉(zhuǎn)變成4~20mADC信號(hào)輸出。壓力變送器是直接與被測(cè)介質(zhì)相接觸的現(xiàn)場(chǎng)儀表，常常在高溫低溫腐蝕振動(dòng)沖擊等環(huán)境中工作。在石油、化工、 電力、鋼鐵、輕工等行業(yè)的壓力測(cè)量及現(xiàn)場(chǎng)控制中應(yīng)用非常廣泛。3151TG 系列智能壓力變送器是公司技術(shù)中心新開發(fā)的一種高精度智能的現(xiàn)場(chǎng)壓力參數(shù)的檢測(cè)儀表，在過程控制系統(tǒng)中具有廣泛的用途，可以來測(cè)量各種介質(zhì)在液體，氣體和蒸汽狀態(tài)下的壓力、液位等參數(shù)，并將被測(cè)的壓力參數(shù)轉(zhuǎn)換成4-20mA標(biāo)準(zhǔn)電信號(hào)輸出，該輸出可以作為指示、記錄和各種控制、調(diào)節(jié)系統(tǒng)的輸入信號(hào)。變送器同時(shí)采用HART協(xié)議傳輸數(shù)字信號(hào)，具有與手操器或上位機(jī)進(jìn)行參數(shù)組態(tài)，在變送器上設(shè)置了就地零點(diǎn)和量程調(diào)整與LCD液晶顯示參數(shù)組態(tài)按鈕，便于現(xiàn)場(chǎng)調(diào)整零點(diǎn)和量程及設(shè)置所需的現(xiàn)場(chǎng)顯示參數(shù)。國(guó)部分地區(qū)仍采用汽暖供熱，比起水暖供熱，汽暖供熱的溫度高，熱量損失也較高，同時(shí)對(duì)于設(shè)備的要求也比水碾高。另外，供熱管網(wǎng)的熱媒和熱源選擇不夠恰當(dāng)、管理不夠細(xì)致周全、供熱管網(wǎng)設(shè)備老化等問題也會(huì)對(duì)供熱管網(wǎng)節(jié)能效果產(chǎn)生影響。3151/3051法蘭式壓力變送器應(yīng)用_供熱管網(wǎng)存設(shè)計(jì)實(shí)用
Pressure transmitter is an important component in many industrial equipment to control industrial process and pressure change. The pressure transmitter is used to measure the liquid level, density and pressure of liquid, gas or steam, and then converts the pressure signal into 4 ~ 20mADC signal output. Pressure transmitter is a field instrument which directly contacts with the measured medium. It often works in the environment of high temperature, low temperature, corrosion, vibration and shock. It is widely used in pressure measurement and field control in petroleum, chemical, electric power, steel, light industry and other industries. 3151TG  Series intelligent pressure transmitter is a kind of high-precision intelligent on-site pressure parameter detection instrument newly developed by the company's technical center. It is widely used in process control system. It can measure the pressure, liquid level and other parameters of various media in liquid, gas and steam state, and convert the measured pressure parameters into 4-20mA standard electrical signal output. The output can be used as Input, control and recording of various indication signals. At the same time, the transmitter uses HART protocol to transmit digital signals, and has parameter configuration with manual controller or upper computer. Local zero point and range adjustment and LCD LCD parameter configuration buttons are set on the transmitter to facilitate on-site adjustment of zero point and range and setting of required field display parameters. Steam heating is still used in some parts of China. Compared with water heating, the temperature of steam heating is higher and the heat loss is higher. At the same time, the requirements for equipment are higher than that of water roller. In addition, the selection of heat medium and heat source is not appropriate, the management is not careful and comprehensive, and the aging of heating network equipment will also affect the energy-saving effect of heating network.
