Operation

特性

Characteristic

    Automatic pump only has entrance side,ａnd no"Vacuum"side.The key issue is that we shoule be conscious of the fact that such automatic pump in this kind could not pump and suck fluid inside.Medium should flow into the pump in virtue of gravity.The more pressure or hesd is,more bigger the CV value of check valve is,secondly,more bigger the CV value of exhaust valve is,the more faster the pace of completion of side circulation will be.Upon completion of liquid charging,control system will shun down exhaust valve and open intake valve.At the moment,steam and compressed gas will expel the liquid from pump.There are some factors influencing velocity of cicle discharging of liquid,including driving the pressure of steam or air,CV value of check valve of exit back valve,downstream back pressure,along with possibility of flowing medium and temperature of surroundings(In case of taking steam as driving air),The last factor is often ignored,but the fact is that steam will be condensed,therefore,reduce actual driving pressure,such phenomenon could be very serious on some applications.

基本原理      

冷凝水控制泵屬于一種壓力控制泵，主要設計用于不適用電力來泵送冷凝水或其他流體的場合。與傳統的電力疏液泵相比，冷凝水控制泵特別適用“困難"介質的疏液，如高溫冷凝水或腐蝕性流體。壓力操作的泵，特別是冷凝水控制泵被*為是長壽命，很少維修的泵。這種泵由于沒有旋轉的密封結構，沒有電動機和泵葉輪，通常使用壽命是傳統電動泵的五到十倍，同時省去了大部分一般性維修。
    1、把高溫凝結水送回鍋爐，節省鍋爐給水化學處理劑，減少制造材料鍋爐給水再加熱的費用。
    2、泵不需要電氣維修。
    3、泵可安全用于危險的或爆炸性的環境。
    4、根據不同的型號，可以用0.5到1.6Mpa表壓力的蒸汽、壓縮空氣或其他氣體操作控制。                                 
    5、疏液量可達22，000Kg/h。
    冷凝水控制泵靠蒸汽或壓縮氣體排出液體。浮球聯到連桿上和彈簧上，同時驅動進汽閥和排氣閥。在充液循環中，進汽閥關閉，同時排氣閥打開，使冷凝水充入泵體內。當浮球隨液位升高到其行程的頂點時，開關控制機構放開彈簧，打開進汽閥，關閉排氣閥。蒸汽或壓縮氣體流入泵內，排出液體。裝在泵進口和出口的逆止閥，使液體在逆止閥的通路方向上流動。   
Basic principle
    The condensate control pump belongs to a pressure control pump and is mainly designed for situations where electricity is not applied to pump condensate or other fluids. Compared with the traditional water pump, the condensate control pump is especially suitable for the "difficult" medium, such as high temperature condensate water or corrosive fluid. Pressure operated pumps, especially condensate control pumps, are recognized as long - lived, rarely - maintained pumps. Because the pump has no rotary seal structure, no motor and pump impeller, the service life is usually five to ten times of the traditional electric pump, and at the same time, most of the general maintenance is omitted.
    1, the high temperature condensate is sent back to the boiler, the chemical treatment agent of boiler water supply is saved, and the cost of reheating the feed water of the manufacturing material boiler is reduced.
    2, the pump does not need electrical maintenance.
    3, the pump can be safely used in dangerous or explosive environments.
    4. According to the different models, the steam, compressed air or other gas can be controlled by the pressure of 0.5 to 1.6Mpa.
    5. The maximum amount of water thinning up to 22000Kg/h.
    The condensate control pump is discharged from the steam or compressed gas. The floating ball is connected to the connecting rod and the spring, and the intake valve and the exhaust valve are also driven. In the liquid filling cycle, the intake valve is closed and the exhaust valve opens, so that the condensate is filled into the pump body. When the floating ball rises with the level of the liquid level to the point of its stroke, the switch control mechanism opens the spring, opens the intake valve, and closes the exhaust valve. Steam or compressed gas flow into the pump and discharge the liquid. A reverse check valve is installed at the inlet and outlet of the pump to make the liquid flow in the direction of the reverse check valve.

安裝及啟動操作

    安裝
    1、凝結水控制泵的安裝位置應保證其上游所有需排入該泵的凝結水均能順利排入，建議進水壓頭為12"(305mm)并能夠正確引入操作蒸汽或壓縮空氣。
    2、在引入操作蒸汽時，其管路接口必須設在操作蒸汽主管道的上方，嚴禁設在主管道下方，以免主管道內的水、雜質等進入操作汽管路。
    3、若凝結水控制泵用來回收多個疏水點排出的凝結水，考慮到不同疏水點排出的凝結水存在不同的余壓，為防止不同疏水點間的相互干擾，建議在凝結水控制泵前安裝集水罐，集水罐的尺寸確定見表。
    4、凝結水控制泵的進出水口必須裝有止回閥，以保證凝結水控制泵的正常運行。建議使用我公司提供的止回閥，以保證泵的排水量。
    5、開式系統凝結水控制泵的安裝建議見圖。
    6、凝結水控制泵需就位在承載能力大于其滿罐時的總重量的地基上。地基表面需平整、干凈。
   7、在將凝結水進出管及操作氣管接入凝結水控制泵之前必須將系統的管路吹掃干凈，以免系統內的污物（如焊渣、鐵銹等）進入凝結水控制泵，損壞泵體上的部件，影響泵的正常工作。
Installation and start operation
install
1, the installation location of condensate control pump should ensure that all upstream condensate discharged into the pump can be discharged smoothly, and the recommended inlet pressure head is 12 "(305mm), which can correctly introduce operation steam or compressed air.
2, in the operation of steam, above the pipeline interface must be located in the operation of a steam main pipe, is prohibited under the main pipe is arranged on the main pipeline, to avoid water and impurities into the operation of the steam pipe.
3, if the condensate pump control is used to recover the more hydrophobic point discharge condensate, taking into account the different hydrophobic point exhaust condensation water have different residual pressure, to prevent the mutual interference 
between different hydrophobic, suggested in the condensed water control pump installed before the water collecting tank, collecting tank size is opinion table.
4. The check valve must be installed in the inlet and outlet of the condensate control pump to ensure the normal operation of the condensate control pump. It is suggested that the check valve provided by our company should be used to ensure the drainage of the pump.
5. The installation of the condensate control pump for the open system is shown in the diagram.
6, the total weight of the water pump to control the setting in place carrying capacity is greater than the full of the ground. The surface of the foundation should be smooth ａnd clean.
7, before condensing water enters and enters the condensate control pump, the pipeline of the system must be swept away, so as to avoid contaminants in the system, such as welding slag and rust, and enter the condensate control pump, which will damage the components of the pump body and affect the normal operation of the pump.

啟 動
檢查確定所有聯接處都連接緊密后，開始試運行。
1.對于蒸汽操作場合，打開進汽口側的疏水管線閥，將管內凝結水排空直至蒸汽出來后關閉該閥。
2.打開出水口閥及排汽口閥。
3.緩慢打開凝結水入口閥，向泵內充水，直至聽到較為平緩的充水聲后，將入口閥*開啟。
Start-up
Check and determine that all joints are connected tightly and start to run.
1. for steam operation occasions, drain pipeline valve to open the steam inlet side, the condensed water pipe emptying out after the valve is closed until the steam.
2. open the outlet valve and exhaust valve.
3. slowly open the condensate inlet valve, fill the pump with water until the more gentle sound of water filling, the entrance valve is completely opened.
