Air preheater is generally referred to as air preheater. More for coal-fired power station boiler. Can be divided into two kinds rotary tube box which is divided into rotary hood rotary and rotary heating surface two. Boiler heating surface is more commonly used air preheater. The application in the boiler is generally divided into three minutes four minutes minutes and the four is often used in the circulating fluidized bed boiler. Mainly by air pre heater to provide lubrication.
The working principle of the tube box preheater: relatively simple the gas flow through the tube from the tube the air is passed through the tube and the temperature difference is different. The same with the economizer superheater the principle of.
The working principle of the air preheater is: preheater rotor parts from tens of thousands of heat transfer components sky pre slow rotators flue gas and air reverse alternately flowing through the air preheater. Heat storage element in the flue gas side of the heat in the air side of the heat so as to reduce the boiler flue gas temperature improve the preheating temperature of hot air.

3G三螺桿泵所輸液體為各種不含固體顆粒,無腐蝕性油類及類似油的潤滑性液體,所輸液體粘度為1.2~100°E(3.0~760cst),高粘度液體亦可通過加溫降粘后輸送。 流量范圍0.2~590m3/h,高工作壓力100bar,高溫度150℃。
3G三螺桿泵(螺桿輸油泵)結構:
1、結構簡單:具有多種結構形式,一般小流量0.2~6.5m3/h,泵的泵體和襯套合為一體(統(tǒng)稱泵體),軸封為機械密封。
中等流量以上的泵襯套為一單獨的零件固定于泵體內,大流量泵多制成雙吸結構臥式安裝,軸封根據輸送介質的不同有機械密封和填料密封兩種。
3G船用泵的安裝形式有臥式和立式兩種,原動機為交、直流船用電動機。
2、壽命長:3G三螺桿泵的主動螺桿由電動機驅動,主、從桿之間沒有機械接觸,而由所輸壓力液體驅使從桿繞軸心線自轉,主、從桿之間、螺桿與襯套之間皆有一層油膜保護,因而泵的機械摩擦極小,壽命堪稱半性。
3、所輸液體在3G三螺桿泵內作軸向勻速直線運動,故壓力脈動小,流量穩(wěn)定,噪音低,由于轉動部件慣性小,則起動力矩和振動很小。
4、3G三螺桿泵具有高吸入能力。
5、為保證3G三螺桿泵、電機及管路系統(tǒng)的安全,中等流量以上的螺桿泵均帶有安全閥,當壓力過安全閥的設定壓力時,高壓油
