麗江高低壓給水加熱器

高壓給水加熱器是利用來自汽輪機的抽汽，來加熱鍋爐給水，使給水達到所要求的溫度，從而提高電廠的熱效率和保證機組的出力。

       低壓給水加熱器是利用汽輪機的低壓抽汽加熱由凝結(jié)泵來的低壓給水，使給水達到所要求的溫度，從而提高電廠的熱經(jīng)濟性，我公司根據(jù)用戶的不同要求，采用不同的設計方案，選擇汽、水流速，傳熱好、汽阻小，進行振動計算、支座的地震計算、管座的推力和推力矩計算。我公司設計的低壓加熱器有立式順U型管、直管等類型，針對不同需要，換熱管可采用銅管、鋼管、不銹鋼管等。采用可靠的安全保護系統(tǒng)，每臺低壓給水加熱器均附有水位顯示器、調(diào)節(jié)和報警裝置，疏水水位自動調(diào)節(jié)，高水位時迅速報警以切除本臺低壓加熱器。在管側(cè)和殼側(cè)均有安全閥以防超壓。山東宏達科技集團有限公司（濟南板式換熱器）是一家集新能源產(chǎn)品、核級壓力容器產(chǎn)品、石油石化產(chǎn)品、環(huán)保工程設計、制造及產(chǎn)業(yè)項目綜合性承包安裝為一體的集團化公司。

  High pressure supply water heater uses discharge steam from steam turbine to heat supply water of boiler, and makes supply water to reach required temperature so as to improve thermal efficiency of power plant and to ensure output of the unit.
  Low pressure supply water heater uses low pressure discharge steam from steam turbine to heat low pressure supply water of condensation pump, makes supply water reach required temperature so as to improve thermal economic performance of power plan. Our company uses different design plans according to different requirements of users, selects optimal steam and water flow speeds, ensures good heat transfer and small steam resistance, and makes vibration calculation, earthquake calculation of base, thrust and thrust torque calculation of pipe seat. Low pressure heat exchangers designed by our company include various types such as vertical smooth U shape pipe and straight pipe. According to different needs, heat exchange pipes can use copper pipe, steel pipe and stainless steel pipe, etc. Reliable safety protective system is used, each low pressure supply water heater has water level indicator, adjustment device and warning device, discharge water level is adjusted automatically, warning is given out at high water level so as to turn off the low pressure heater. Safety valves are set on pipe side and casing side so as to prevent overpressure.
