Basic knowledge
WDV20 condensate water automatic pump belongs to a sort of pressure control pump,designed for the occasion where condensate water and other fluid are pumped through the way beyond electric power.Compared with conventional infusion pump,condensate water control pump is very suitable for transmission of "Difficult"medium,such as high temperature condensate water or corrosive fluid.Pressure controlled pump,particular in condensate water automatic pump,are recognized as long-life pump with seldom maintenance needed.The pump is five to ten times the life of traditional ones due to its absence of electromotor, pump impeller and rotary seal structure,at the same time,general maintenance of it will be saved dramatically.
1、It's necessary to return high-temp condensate water into boiler,in order to save boiler water supply and chemical treating agent,and reduce boiler water supply and the cost of reheating.
2、No need to carry out electrical maintenance.
3、It could be used safely in dangerous and explosive environment.
4、It may be used in gauge pressure with capacity from 5 to 250 Psig(1.72MPa)according to different types,and compressed air or other air operation and control.
5、Lyophobe may reach maximum volume of 48,000 pounds/hour(22,000Kg/hr)
運行
冷凝水自動泵靠蒸汽或壓縮氣體排出液體。浮球連到連桿和彈簧上，同時驅動進氣閥和排氣閥。充液循環中，進氣閥關閉，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，開關控制機構釋放彈簧，打開進氣閥，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，使液體在對應的道路方向上流動。Operation
Condensate water automatic pump discharges liquid by depending on steam or compressed air.Float ball will be linked to connecting rod and spring,simultaneously,drive intake valve and exhaust valve.The intake value will shut down during circulation of liquid charging,at the same time,exhaust valve will open,enabling condensate water into the pump.As the float ball rise with the liquid up to the peak of its journey,the switch control system will set spring free and open intake valve,as well as close exhaust valve.Steam and compressed air subsequently flow into pump and discharge liquid.The check valve that fixed at intake of exhaust of pump will drive the liquid flowing in opposite path.特性
疏液能力取決于幾個參數。應注意的是冷凝水自動泵排出的是間斷液流，總排液量取決于循環的快慢。驅動壓力的大小和流動路線上的阻力是排水能力的明顯成因和限制因素。其次是逆止閥的CV值、充入液體的壓力或壓頭、排氣管路的阻力以及驅動氣體的特性。自動泵沒有“真空”側，只有入口側。重要的是要懂得冷凝水自動泵這種類型的泵不會抽入或吸入流體。介質必須借助重力流入泵內。壓力或壓頭越高，入口逆止閥的CV值越大，其次是排氣閥的CV值越大，則循環的充液階段完成的越快。完成充液階段后，控制機構將關閉排氣閥打開進氣閥。這時蒸汽或壓蒸汽或縮氣體會排出泵體內的液體。影響循環排液階段速度的因素包括驅動蒸汽或氣體的壓力、出口逆止閥的CV值、下游的背壓，可能還有流動介質和周圍環境的溫度（如果蒸汽用作驅動氣體的話）。這最后一個因素經常被忽略，但事實是，蒸汽會被冷凝，從而減少實際的驅動壓力，在某些應用場合，這一現象還很嚴重。
Characteristic
Lyophobe capacity is determined by several parameters.The thing to be noticed is the fact that it's discontinuous liquid that condensate water automatic pump released is,the amount of liquid discharging should rest with the speed of circulation.The size of driving pressure and resistance of flowing path are distinct elements and limiting factors,Secondly,it should be attributable to some factors,such as CV value of check valve,the pressure or head of charging liquid,resistance of exhaust pipe,and characteristic of driving gas.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.

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。

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.
