LPG涡轮泵


WB10/15系列涡轮泵是根据涡轮增压原理由淄博华创燃气设备开发有限公司研制和开发的新型液体抽吸、输送、加压设备。该系列产品设计独特,结构精巧,升压快、压差大、流量稳、扬程远、噪音小等特点,并适合连续和频繁的启动工作。主要用于输送地上贮存和地下贮存的液化石油气(LPG)、丙烷、丁烷、丙烯、液氨等液态介质,广泛使用在液化气汽车加气站、液化气灌装储备站、炼油厂、石化厂等场所以及石油石化行业。

HCW10/15系列涡轮泵由两级泵室组合而成,一级为大空间吸入腔的高速离心泵,主要完成抽入功能;二级为加工精密的涡轮泵,主要完成加压和输送功能,由于采用了两级组合平衡式结构,在泵的使用功能增强的同时,安全性能得到本质提高,确保泵在运行过程中无泄漏。

工作原理,首先打开一级泵室吸入腔上的放气阀,将腔内减压,使贮罐内的液体灌满吸入腔(吸入管在进吸口前最好抬高并超过吸入腔高度),然后关闭放气阀,启动电机。此时泵开始高速旋转,预先灌入腔内的液体沿叶轮切线方向抛出从而在叶轮中心吸入腔内形成挤压,产生强大吸力,将贮罐内液体连续抽出,吸入负压使吸入液体造成的部分汽化产生的气泡进入中间过度消气管,受排出压力作用,腔内气泡达到饱和压力而重新液化,再进入二级涡轮泵室内压缩排出。因预先已消除气泡,所以不会出现其他容积式泵加压时因气泡被挤碎而产生的噪音、剧烈震动、机件损坏从而出现频繁故障等缺陷。

The WB10/15 series turbo pump is a new type of equipment for liquid pumping, delivering and pressurization, researched and developed by zibo Huake Gas Equipment Development Co., Ltd, based on the principle of turbocharger. Products of this series have unique design and delicate structure with the following features: quick boost-up pressure, large pressure difference, steady rate of flow, far lift, and small noise and so on. Besides, this type of pump is suitable for continuous and frequent start-up work. This series of products are widely used in petroleum and petrochemical fields, such as; liquefied gas filling station, liquefied gas storage station, oil refinery, and petro-chemical plant. Mainly for delivering of liquid medium, which are stored above or underground, such as LPG (Liquefied Petroleum Gas), liquefied propane gas, butane, and propylene and liquid ammonia.


The HKW10/15 series turbo pump is composed of two levels of pump chambers. Level one is high-speed centrifugal pump with large suction chamber, mainly to complete the suction function; level two is turbo pump with precise machining, mainly to complete pressurization and delivering function. Since the balanced structure is adopted for this kind of bipolar combination pump;therefore, when the pump's function of use is enhanced, its safety performance is also improved essentially, which can ensure the pump has no leakage during operation.


lts working principle is as follows: firstly, open the air release valve in level one suction pump chamber to reduce the pressure in the chamber; let the suction chamber filled with liquid from the storage tank (It is better to raise the suction pipe to a height which is higher than the suction chamber before it enters the suction port.) ;then close the air release valve and start up the motor. At this time, the pump starts to rotate at high speed. The liquid pre-suctioned in chamber will be lifted along the tangent line of the impeller and formed extrusion in the center of the impeller through suction, which will generate super strong attractive force to continuously pump out the liquid in the storage tank. The negative suction will push the air bubble, generated from partial vaporization caused by pumping in liquid, into the transitional dissipation pipe in the middle. Under the discharge pressure, the air bubbles inside the chamber are back to liquid again because it already reaches saturation pressure. Then the liquid will enter into the level two turbo pump chamber again for further compression and discharge. For other volumetric pumps, big noise, severe vibration and components damage caused by the crushed air bubbles when applying pressure will probably happen, which in turn will lead to frequent failure. However ,for this kind of pump, those failures will not happen, because the air bubbles inside already have been eliminated in advance.
