据估计,美国有2300万户房屋从私人井中获得饮用HomeHome水,其中大多数井包括一个或多个储水箱,可能需要修理甚至更换。bob体育app苹果下载
这些坦克与泵,压力表和阀门配合使用,以保持一致的水压,存放水供立即使用,并增加家庭管道系统中组件的寿命。HomeHome继续阅读以了解不同类型的well water tanks并找出如何为房屋的饮用水供应系统选择合适的选择。HomeHome
Pressure Tanks Manage Water Supply
几乎所有现代水井都包括通常称为压力箱的水井。这通常是一个高大的油漆钢或玻璃纤维缸,位于来自井泵的管道和房屋其余部分之间的管道之间。HomeHome
This tank has two main jobs: It ensures that there is sufficient but not excessive water pressure in your pipes, and it holds a reserve of water so that your well pump isn’t switching on and off every time there is demand for water somewhere in the system.
井水箱如何保持水压
向所有房屋的固定装置和设备提供水需要压力。HomeHome如果没有足够的压力,电器将无法正常工作。也就是说,太大的压力会导致整个管道系统中的泄漏和过早的磨损。一个井水箱与井泵,压力开关和止回阀结合使用,以使水压保持在安全舒适的范围内。
水箱内是一个橡胶膀胱,类似于轮胎内文化管,该轮胎的空气固定了加压空气,将水迫使水从水箱中伸出并进入您的管道。储罐上的压力开关告诉井泵时,当储罐压力降至令人满意的距离距离30或40磅的底部时,井泵要打开。一旦压力到达所需范围的顶部,通常是50或60psi,开关关闭了井泵。水箱和泵之间的单向止回阀可防止压力向下泄漏到井中。
选择正确的压力箱
The correct size tank is one that holds enough water in reserve to allow the well pump to run for a manufacturer-specified number of minutes each time it turns on in order to minimize wear and tear on the pump. If you are replacing a faulty tank, you may be able to just buy a tank that is the same size as the old one, but it’s safer to contact a tank distributor to help you choose the right one.
Pressure tanks are measured in water capacity-which can range from just a couple gallons to over a hundred. The ideal size tank for any plumbing system is based on what is called the drawdown rate, which is a function of the flow rate of the well pump, the pump’s minimum runtime, and the on and off settings of the tank pressure switch. Collect those numbers and then call a tank manufacturer’s tech support line to get help choosing.

Why Some Wells Have Additional Storage Tanks
The amount of water any well can provide in a day is limited by the flow capacity of the well itself. A slow-flowing well may work fine for some homes, but if you have a big family, a garden that needs frequent watering, or a hot tub that regularly needs topping off, an underperforming well may periodically run dry. When a well doesn’t keep up with a home’s demand, sometimes the owners may choose to drill a deeper well. But you can also add one or more storage tanks, which can often be a more affordable option.
How a Storage Tank Works
Non-pressurized storage tanks-also called cisterns-don’t replace the pressure tank in a well system. Instead, they get installed between the well pump and the pressure tank, providing a large reserve that the home can draw from when demand for water is high—without running the well dry.
In a pumped storage system, the well pump is controlled by a float valve in the storage tank rather than running off of a pressure switch. When the tank gets low, the valve will tell the pump to run continuously until the tank fills back up. The pump will also automatically turn off if the well runs dry, but under normal conditions that won’t impact the home’s water supply, as there will still be reserve supply in the tank.
随着技术的改进,现代储罐,例如Epp Well Solution System, have replaced the simple float valve with digital flow meters that constantly monitor the output of the well to more efficiently manage backup water supply.
Selecting the Right Size Storage Tank
储水中需要多少容量系统取决于您将在高峰需求下使用多少水。对于一个小家庭,一个200加仑的储罐可能有足够的时间在早上提供几次淋浴,偶尔会因假日聚会或装满小浴缸而造成的高需求。
如果房屋举办大型聚会,有超大浸泡浴缸或支撑大型菜园,则需要更大的水箱。另外,一个非常缓慢的井或容易干旱地区的井可能需要一个超过一天的储备金的水箱。bob体育app苹果下载为了为您提供正确的井储水箱,您需要做一些功课来估算您的高峰需求以及重新填充储罐所需的时间。HomeHome坦克分销商和制造商将拥有知识渊博的员工,以帮助您弄清楚这一点。
与压力箱相比,储藏箱的形状,尺寸和材料更多,因此很难决定bob体育app苹果下载购买哪种类型。如果您需要将它们安装在地下室,而访问有限,则小型塑料罐可能是最有意义的。某些类型的钢,塑料和玻璃纤维罐可以埋葬地下以节省空间。确定理想水箱类型的因素会因位置而异,因此最好与当地的井系统安装程序或您的建筑部门核对以做出明智的决定。
储罐不能取代压力箱
Because storage tanks do not pressurize water, a home with one of these tanks will still need a pressure tank. And because the primary well pump is filling the storage tanks and not directly feeding the pressure tank, an additional pressure pump is necessary between the storage and pressure tanks to actually provide the home’s water pressure. In other words, a storage system for a low-yielding well adds to the complexity and cost of the system-but if your well isn’t meeting your demands, it will likely be an essential expense.
