进口蒸汽往复泵-进口往复泵-德国KAYSEN泵业

GERMANY KAYSEN PUMP CO .,LTD

德国凯森电动往复泵是用蒸汽为动力,根据唧筒原理作用的一种抽水设备。各种蒸汽往复泵的汽缸工作压力为1.4Mpa,排出压力为1.7Mpa,适用于饱和蒸汽和过热蒸汽,气温不超过200℃。

   各种蒸汽往复泵所配水缸活塞环,只适用于水温不能超过60°C,超过该温度而在105°C以内者,须换掉优质帆布夹层填料来制选水缸活塞环。各种蒸汽往复泵的理论吸程为10.3米,但实际使用时吸水扬程包括管道阻力在内不应超过7米,当抽吸热水时吸水扬程随水温升高而降低,若水温过高或管道阻力过大,进水池*水位须高于蒸汽泵的汽缸、水缸平直中心线。

主要特点:

泵的排出压力取决于蒸汽压力,由于汽缸面积比水缸面积一般要大2~2.5倍,因此能获得较高的压力。如不计磨擦阻力损失,在水缸活塞上能产生2~2.5倍锅炉蒸汽压力的水压力。

泵的流量取决于蒸汽的流量,调节比较方便。这种泵不能用调节出水管上阀门的开度的节流方法来调节流量。一般用调节进汽阀门的开度来调节流量,也可以用出水管旁路回流到进水管的办法调节流量。这种泵能适应较大的负荷变化。

有较高的效率,一般可达80%~95%。

但蒸汽往复泵结构笨重,体型较大,传动机构复杂,操作较麻烦,耗用蒸汽多,成本较高。由于这些原因,基本上已不用蒸汽往复泵作为锅炉的主要给水设备,一般只作为停电时的备用泵。但有些锅炉房考虑省煤器的连续进水,仍把便于调节流量的蒸汽往复泵作为锅炉的日常给水设备。

2QS(QB)型卧式双缸、双作用、活塞式蒸汽往复泵是以蒸汽为动力,根据唧筒原理作用的一种抽水设备。它的主要优点是结构简单,安装、使用和维护方便。只要连接上蒸汽和进出水管道即可使用,既可用于一般输水,也可用于中小型锅炉给水。如调换缸内活塞和某些零件,亦可用于炼油厂输送石油产品、矿井排水等。

各种蒸汽泵的汽缸工作压力为1.4Mpa,温度不超过200℃,*排出压力为1.7Mpa,被输送液体常温为60℃,泵启动蒸汽压力不低于0.3Mpa,适用于饱和蒸汽和过热蒸汽.

 

主要应用:

中小型锅炉给水

炼油厂输送石油产品

矿井排水

Germany Kaysen electric reciprocating pump is a pumping device that uses steam as the power and acts according to the principle of the cylinder. The various steam reciprocating pumps have a cylinder working pressure of 1.4 MPa and a discharge pressure of 1.7 MPa, which is suitable for saturated steam and superheated steam, and the temperature does not exceed 200 °C.


   The piston rings of various steam reciprocating pumps are only suitable for water temperature not exceeding 60 °C. If the temperature exceeds 105 °C, the high-quality canvas sandwich packing should be replaced to select the cylinder piston ring. The theoretical suction stroke of various steam reciprocating pumps is 10.3 meters, but in actual use, the suction head should not exceed 7 meters including pipe resistance. When the hot water is pumped, the suction head decreases with the increase of water temperature, if the water temperature is too high. Or the pipeline resistance is too large, the minimum water level in the inlet pool must be higher than the flat center line of the cylinder and the water tank of the steam pump.



main feature:


● The discharge pressure of the pump depends on the steam pressure. Since the cylinder area is generally 2 to 2.5 times larger than the cylinder area, a higher pressure can be obtained. If the frictional resistance loss is not counted, a water pressure of 2 to 2.5 times the boiler steam pressure can be generated on the cylinder piston.


●The flow rate of the pump depends on the flow rate of the steam, and the adjustment is convenient. This type of pump cannot regulate the flow by a throttling method that regulates the opening of the valve on the outlet pipe. Generally, the opening of the inlet valve is adjusted to adjust the flow rate, and the flow rate can also be adjusted by bypassing the outlet pipe to the inlet pipe. This pump can accommodate large load changes.


● It has high efficiency, generally up to 80% to 95%.


However, the steam reciprocating pump has a cumbersome structure, a large body shape, a complicated transmission mechanism, troublesome operation, high steam consumption, and high cost. For these reasons, the steam reciprocating pump has basically not been used as the main water supply device of the boiler, and generally only serves as a backup pump at the time of power failure. However, some boiler houses consider the continuous water intake of the economizer, and still use the steam reciprocating pump that is convenient to adjust the flow rate as the daily water supply equipment of the boiler.


2QS (QB) horizontal double-cylinder, double-acting, piston-type steam reciprocating pump is a kind of pumping equipment that is powered by steam and acts according to the principle of the cylinder. Its main advantages are its simple structure and its ease of installation, use and maintenance. It can be used as long as it is connected to steam and water inlet and outlet pipes. It can be used for both general water supply and medium and small boiler feed water. Such as the replacement of the cylinder piston and some parts, it can also be used in oil refineries to transport petroleum products, mine drainage and so on.


The working pressure of the cylinders of various steam pumps is 1.4Mpa, the temperature does not exceed 200°C, the maximum discharge pressure is 1.7Mpa, the normal temperature of the liquid to be transported is 60°C, and the steam pressure of the pump starts is not less than 0.3Mpa. It is suitable for saturated steam and superheated steam. .


 


main application:


●Small and medium boiler water supply


●Refinery transports petroleum products


● Mine drainage



Steam reciprocating pump failure and treatment methods:

Steam reciprocating pumps will have various problems during operation, and timely maintenance and maintenance will ensure normal operation. First summarize the phenomena, causes and treatments that may cause problems in production as follows:


First, the pump does not move


the reason:


(1) The inlet valve spool is broken, so that the valve cannot be opened.


(2) There is water in the cylinder


(3) Rocker pin off or taper pin cut


(4) Damage to the piston rings of steam and cylinder


(5) Excessive cylinder wear clearance


(6) Poor contact between valve disc and valve seat


(7) Insufficient steam pressure


(8) The piston rod is in the middle position, causing the valve to close


(9) The discharge valve valve plate is reversed, so that the outlet is closed.


Approach:


(1) Replace the valve or spool


(2) Open the drain valve to remove water from the cylinder


(3) Install the rocker pin and replace the taper pin


(4) Replace the petrol cylinder piston ring


(5) Replace the cylinder or piston ring


(6) Grinding valve plate and seat


(7) Adjusting steam pressure


(8) Adjust the position of the piston rod


(9) Reinstall the discharge valve correctly


Second, pump pumping


the reason:


(1) The inlet temperature is too high to produce vaporization, or the liquid level is too low to draw in gas


(2) The inlet valve is not open or opened small


(3) The piston nut is loose


(4) The inlet and outlet are connected because the inlet valve gasket is blown


(5) The cylinder liner is worn and the piston ring is out of order


Approach:


(1) Reduce the inlet temperature, ensure a certain liquid level or adjust the number of reciprocating times


(2) Open the inlet valve to a certain opening degree or adjust the number of reciprocating times


(3) Tightening the piston nut


(4) Replace the inlet valve gasket


(5) Replace the cylinder liner or piston ring


Third, produce a sound or vibration


the reason:


(1) Excessive piston stroke or vaporization evacuation

(3) Loose cylinder liner


(4) After the valve is broken, the debris falls into the cylinder


(5) Loose ground screws


(6) The crosshead center frame connection is loose


Approach:


(1) Adjust piston stroke and number of reciprocations


(2) Tighten the piston nut and piston rod, nut


(3) Tighten the cylinder cover screws


(4) Remove the debris in the cylinder and replace the valve


(5) Fixed anchor bolt


(6) Repair or replace the crosshead


Fourth, the gland leaks oil, leaks


the reason:


(1) The piston rod is worn or the surface is not smooth


(2) Damage to the packing


(3) The packing gland is not tightened or insufficient packing


Approach:


(1) Replace the piston rod


(2) Replace the packing


(3) Filling or tightening the gland


Five, cylinder piston rod overheating


the reason:


(1) Oiler check valve fails


(2) Insufficient lubrication


(3) The packing is too tight


Approach:


(1) Replace the check valve


(2) Add enough lubricant


(3) Loose packing gland


Sixth, the pressure is unstable


the reason:


(1) The valve is not tight or the spring force is uneven


(2) The piston ring is not flexible in the groove


Approach:


(1) Grinding valve or replacement spring


(2) Adjust the fit of the piston ring to the groove


Seven, insufficient traffic


the reason:


(1) The valve is not strict


(2) The clearance between the piston ring and the cylinder liner is too large


(3) too few strokes


(4) Stroke is too short


Approach:


(1) Grinding or replacing the valve, adjusting the spring


(2) Replace the piston ring or cylinder liner


(3) Adjust the number of strokes


(4) Adjusting stroke, etc.
