蒸汽往復(fù)泵-往復(fù)泵-KAYSEN泵業(yè)

GERMANY KAYSEN PUMP CO .,LTD

凱森電動(dòng)往復(fù)泵是用蒸汽為動(dòng)力，根據(jù)唧筒原理作用的一種抽水設(shè)備。各種蒸汽往復(fù)泵的汽缸工作壓力為1.4Mpa，排出壓力為1.7Mpa，適用于飽和蒸汽和過(guò)熱蒸汽，氣溫不超過(guò)200℃。

   各種蒸汽往復(fù)泵所配水缸活塞環(huán)，只適用于水溫不能超過(guò)60°C，超過(guò)該溫度而在105°C以?xún)?nèi)者，須換掉優(yōu)質(zhì)帆布夾層填料來(lái)制選水缸活塞環(huán)。各種蒸汽往復(fù)泵的理論吸程為10.3米，但實(shí)際使用時(shí)吸水揚(yáng)程包括管道阻力在內(nèi)不應(yīng)超過(guò)7米，當(dāng)抽吸熱水時(shí)吸水揚(yáng)程隨水溫升高而降低，若水溫過(guò)高或管道阻力過(guò)大，進(jìn)水池*水位須高于蒸汽泵的汽缸、水缸平直中心線。

主要特點(diǎn)：

●泵的排出壓力取決于蒸汽壓力，由于汽缸面積比水缸面積一般要大2～2.5倍，因此能獲得較高的壓力。如不計(jì)磨擦阻力損失，在水缸活塞上能產(chǎn)生2～2.5倍鍋爐蒸汽壓力的水壓力。

●泵的流量取決于蒸汽的流量，調(diào)節(jié)比較方便。這種泵不能用調(diào)節(jié)出水管上閥門(mén)的開(kāi)度的節(jié)流方法來(lái)調(diào)節(jié)流量。一般用調(diào)節(jié)進(jìn)汽閥門(mén)的開(kāi)度來(lái)調(diào)節(jié)流量，也可以用出水管旁路回流到進(jìn)水管的辦法調(diào)節(jié)流量。這種泵能適應(yīng)較大的負(fù)荷變化。

●有較高的效率，一般可達(dá)80%～95%。

但蒸汽往復(fù)泵結(jié)構(gòu)笨重，體型較大，傳動(dòng)機(jī)構(gòu)復(fù)雜，操作較麻煩，耗用蒸汽多，成本較高。由于這些原因，基本上已不用蒸汽往復(fù)泵作為鍋爐的主要給水設(shè)備，一般只作為停電時(shí)的備用泵。但有些鍋爐房考慮省煤器的連續(xù)進(jìn)水，仍把便于調(diào)節(jié)流量的蒸汽往復(fù)泵作為鍋爐的日常給水設(shè)備。

2QS(QB)型臥式雙缸、雙作用、活塞式蒸汽往復(fù)泵是以蒸汽為動(dòng)力，根據(jù)唧筒原理作用的一種抽水設(shè)備。它的主要優(yōu)點(diǎn)是結(jié)構(gòu)簡(jiǎn)單，安裝、使用和維護(hù)方便。只要連接上蒸汽和進(jìn)出水管道即可使用，既可用于一般輸水，也可用于中小型鍋爐給水。如調(diào)換缸內(nèi)活塞和某些零件，亦可用于煉油廠輸送石油產(chǎn)品、礦井排水等。

各種蒸汽泵的汽缸工作壓力為1.4Mpa，溫度不超過(guò)200℃，*排出壓力為1.7Mpa，被輸送液體常溫為60℃，泵啟動(dòng)蒸汽壓力不低于0.3Mpa,適用于飽和蒸汽和過(guò)熱蒸汽.

主要應(yīng)用：

●中小型鍋爐給水

●煉油廠輸送石油產(chǎn)品

●礦井排水

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

(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

(2) Loose piston nut or piston rod nut

(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.
