工作原理


Working Principle


 


现以NZP系列落地式膨胀水箱为例说明其工作原理。NZP系列设备由气压罐、定压补水罐、电控柜、压力控制器、安全阀、压力表、阀门及管道等组成的一个完善的全自动定压补水装置。气压水罐由内、外两室组成,内室(橡胶囊内部)为水室。外室(橡胶囊与设备外壳之间)为充满氮气的气室。


Let’s take the NZP series floor type expansion water tank for example to introduce its working principle. NZP series device is a complete fully automatic constant pressure water makeup device composed of air pressure tank, constant pressure water makeup tank, electrical cabinet, pressure controller, safety valve, pressure gauge, valve and pipeline. Air pressure tank is composed of external and internal chambers, with the internal chamber (inside of rubber bag) as the water chamber while the external chamber (the space between rubber bag and device shell) as the air chamber full of nitrogen gas.










  





  











  













该设备采用系统静压作为膨胀水箱内的设计初始压力水头P1,采用保证系统内热水不汽化的压力作为膨胀水箱内运行终端压力水头P2。初始运行时首先启动补水泵向系统及气压罐内的水室中充水,系统充满后多余的水被挤进胶囊内。 因为水的不可压缩性,随着水量的不断增加,水室的体积也不断的扩大而压缩气室,罐内的压力也不断的升高。当压力达到设计压力时,通过压力控制器使补水泵关闭。 当系统内的水受热膨胀使系统压力升高超过设计压力时,多余的水通过安全阀排至补水箱循环使用,当系统中的水由于泄露或温度下降而体积缩小,系统压力降低时,胶囊中的水被不断压入管网补充系统的压降损失,当系统压力降至设计允许的最低压力时,通过压力控制器使补水泵重新启动向管网及气压罐内补水,如此周而复始的工作,完成了高位膨胀水箱所起到的作用,同时不存在真空或缺水的现象,保证水的流量,压力永不失调。举例:罐体直径为1600mm,罐体个数为1,水泵吸入口径为50mm,水泵数量为2,水泵级数为3级的囊式落地膨胀水箱表示为NZPl.6 x 1-50 x 2 X 3。


This device uses the system static pressure as the designed initial pressure head P1 in expansion water tank and uses the pressure not causing vaporization of hot water in the system as the running terminal pressure water head P2 in the expansion water tank. In initial running, firstly start the make-up water pump to fill water into the system and water chamber in air pressure tank, and then the excess water will be forced into the rubber bag after the system is full of water. The volume of water chamber will keep expanding with the increasing of water volume due to the incompressibility of water, and then the air chamber will be compressed to make the pressure in tank increase continually. The make-up water pump will be closed through the pressure controller when reaching the design pressure. When the water in system expands by heat, which makes the system pressure increase and exceed the design pressure, the excess water will be discharged to make-up water tank through safety valve for recycling; when the volume of water in the system decreases due to water leakage or temperature drop, which makes the system pressure decrease, water in rubber bag will be pressed into pipe network to make up the loss of pressure drop of the system; when the system pressure is dropped to the minimum pressure allowed by the design, the make-up water pump will be re-started through the pressure controller to make up water into the pipe network and air pressure tank; such continuous cycle enables the high expansion water tank to realize its function without causing vacuum or water shortage phenomenon and guarantees the water discharge and never disorder pressure. For example, diameter of tank body 1600mm, quantity of tank 1, water pump suction caliber 50mm, and quantity of water pump 2, so the bag type floor expansion water tank with series 3 pump shall be expressed as NZPl.6 x 1-50 x 2 X 3.
