  增压泵顾名思义,是指具备全自动启停功能的加压泵。简单地说,用水的话,加压泵会自动打开。 不用水的话,增压泵会自动停止。这就是原始的自动加压泵——差压式自动加压泵。但是,增压泵并不是用水自动、不用水就停止的简单泵,那么,下面一起了解下如何选择增压泵及工作原理吧!

A booster pump, as the name suggests, is a pressure pump with fully automatic start-stop function. Simply put, it starts automatically when water is drawn and stops when water is not in use. This is the traditional differential pressure type automatic booster pump. However, booster pumps are more sophisticated than pumps that merely turn on and off with water consumption. Below is an introduction to their working principles and selection methods.

  传统自动增压泵的工作原理

  差压式自动增压泵是简单、便宜的自动增压泵。其控制原理是,加压泵运转时,压力逐渐上升到设定的上限值,达到上限值时,增压泵被切断电源停止运转;加压泵停止工作后,如果管网用户继续使用水,管网的水压将下降到设定的下限值,开关启动时加压泵重新启动。往复循环运行实现了传统自动增压泵的自动供水功能。据了解,除工业用水外,一般用水量随时间减少。在传统的增压泵控制机制中,增压泵频繁停止,频繁停止容易烧毁电机和控制部件,用户的间接影响是水压的大小。最大的影响是热水器出水后会变冷。显然,在目前的物质条件和人们的消费理念下,传统的差压式自动增压泵越来越不能满足实际的需要。

Working Principle of Traditional Automatic Booster Pumps

The differential pressure automatic booster pump is a simple and cost-effective type. Its control principle is as follows: When the pump runs, the water pressure gradually rises to the preset upper limit, at which point the power supply is cut off and the pump stops. After shutdown, if water is continuously used in the pipe network, the water pressure will drop to the preset lower limit, and the switch will trigger the pump to restart. This cyclic operation realizes the automatic water supply function of traditional automatic booster pumps.
In general domestic water scenarios excluding industrial use, water consumption tends to decrease over time. The control mechanism of traditional booster pumps leads to frequent start-stop cycles. Frequent operation may burn out the motor and control components. For users, it causes fluctuating water pressure, and most noticeably, the outlet water of water heaters turns cold intermittently. Obviously, given current living standards and consumption demands, traditional differential pressure automatic booster pumps can no longer meet practical application requirements.

  新型自动加压泵的定义

  随着自动化技术和工程技术的发展,自动增压泵当然也在升级和变化。新型自动加压泵不仅可以实现全自动启停的功能,还可以根据用户的水大小自动调节设备的转速实现恒压供水的功能。恒压的自动加压泵就是人们常说的变频自动加压泵。变频自动增压泵的基本控制理念是有压力差就能弥补压力,设备的实际运行功率与用水量的大小有关。因此,变频器自动加压泵也比较节能。

Definition of New-type Automatic Booster Pumps

With the advancement of automation and engineering technologies, automatic booster pumps have also been upgraded. New-type automatic booster pumps can not only realize fully automatic start and stop, but also adjust the rotating speed automatically according to water flow to maintain constant water pressure. Such constant-pressure automatic booster pumps are commonly known as variable frequency automatic booster pumps. Its core control logic is to compensate pressure in response to pressure difference. The actual operating power varies with water consumption, so variable frequency booster pumps feature outstanding energy-saving performance.



  新型自动加压泵的工作原理

  变频器自动增压泵控制基于闭环控制的理念而不是上下限压力值来执行。闭环控制是根据控制对象的反馈进行补偿的控制方式,是在测量到实际与计划产生偏差的情况下,根据定额和基准进行补偿的方式。闭环控制从输出量的变化中提取控制信号,作为比较量反馈到输入端,以控制输入量。一般来说,该提取量和输入量的相位相反,因此被称为负反馈控制,工业化自动控制通常基于闭环控制的理念。

Working Principle of New-type Automatic Booster Pumps

The control of variable frequency booster pumps adopts closed-loop control instead of pressure upper and lower limit control. Closed-loop control performs compensation based on feedback from the controlled object. When deviation occurs between the actual value and the set value, compensation is implemented according to the preset reference standard.
It extracts control signals from changes in output variables and feeds them back to the input terminal as comparison signals to regulate input variables. Generally, the phase of the feedback signal is opposite to that of the input signal, so this is also called negative feedback control. Closed-loop control is widely applied in industrial automatic control systems.
