VOLIYA-SPS系列定压补水装置是一种在各类流体系统中发挥关键作用的设备，主要分为气压式和常压定压补水排气装置两种类型。气压式定压补水装置依靠稳压罐来实现系统压力的稳定调节，当系统水体发生膨胀或收缩时，稳压罐能够自动进行充水和补水操作，确保系统压力始终维持在稳定状态。常压定压补水排气装置则通过常压罐和定压泵的协同工作，实现系统压力的平衡，同时具备补水、排气和泄压等功能，有效保障系统的正常运行。

The VOLIA-SPS series constant pressure water supply device is a key equipment that plays a crucial role in various fluid systems. It is mainly divided into two types: pneumatic and atmospheric constant pressure water supply and exhaust devices.

When the water body in the system expands or contracts, the pressure stabilizing tank can automatically perform water filling and replenishment operations to ensure that the system pressure remains stable at all times. The atmospheric pressure constant pressure water replenishment and exhaust device achieves pressure balance in the system through the coordinated operation of the atmospheric pressure tank and the constant pressure pump. It also has functions such as water replenishment, exhaust and pressure relief, effectively ensuring the normal operation of the system.

该装置通常由罐体、水泵、阀门、控制系统等部件组成，具有结构紧凑、操作简便、运行可靠等优点，能够根据不同系统的需求进行灵活配置和调整，广泛应用于各种需要稳定压力和水质的领域。

This device is usually composed of a tank, a water pump, valves, a control system and other components. It features a compact structure, simple operation and reliable operation. It can be flexibly configured and adjusted according to the requirements of different systems and is widely used in various fields that require stable pressure and water quality.

工作原理Working principle

定压补水装置的工作原理根据其类型的不同而有所差异，下面分别介绍气压式和常压定压补水排气装置的工作原理。

The working principle of constant pressure water supply devices varies depending on their types. The following introduces the working principles of pneumatic and atmospheric constant pressure water supply and exhaust devices respectively.

气压式定压补水稳压：当系统的水体膨胀时，膨胀水会自动充入稳压罐内。稳压罐内的气体被压缩，压力升高，从而吸收了系统中多余的水量。当水体收缩时，稳压罐内的压力降低，存水会自动补入系统管道内，以维持系统压力的稳定。当系统压力降至最小值时，稳压泵启动，向系统补水，直到系统压力达到最大值时停止，从而将系统压力维持在安全范围内。若系统压力超过极限值时，安全阀会自动泄压，确保系统的安全运行。

Pneumatic constant pressure water supply and pressure stabilization: When the water body in the system expands, the expanded water will automatically fill the pressure stabilizing tank. The gas in the pressure stabilizing tank is compressed, and the pressure rises, thereby absorbing the excess water in the system. When the water body contracts, the pressure in the pressure stabilizing tank drops, and the stored water will be automatically replenished into the system pipeline to maintain the stability of the system pressure. When the system pressure drops to the minimum value, the pressure stabilizing pump starts to replenish water to the system and stops when the system pressure reaches the maximum value, thereby maintaining the system pressure within a safe range. When the system pressure exceeds the limit value, the safety valve will automatically release the pressure to ensure the safe operation of the system.

常压定压补水排气：当系统压力过高时，系统中的水会溢流入常压罐，直到系统压力恢复到设定值。当系统压力过低时，定压泵将常压罐中的水注入系统中，直至系统压力恢复到设定值。在补水方面，定压补水排气装置借助常压罐上的液位传感器检测罐内的水位。如果水位降到低于设定值，补水电动阀开启，向膨胀罐中补水，直到水位达到设定上限时才关闭补水电动阀。在排气方面，系统中高压的水进入常压罐后，由于气体在常压水中的溶解度低于在高压水中的溶解度，多余的气体就会从水中析出，并通过罐子顶部的自动排气阀排出。水泵将已经处理完的水再打回系统，使系统水中含气量呈现不饱和状态，从而能再去吸附系统中的游离气体，通过这样一个循环过程，有效地达到排气效果。若系统压力超过极限值、且常压罐内水处于高液位时，安全阀会自动泄压，保障系统安全。

Atmospheric pressure constant pressure water replenishment and exhaust: When the system pressure is too high, the water in the system will overflow into the atmospheric pressure tank until the system pressure returns to the set value. When the system pressure is too low, the constant pressure pump injects water from the atmospheric pressure tank into the system until the system pressure returns to the set value. In terms of water replenishment, the constant pressure water replenishment and exhaust device uses the liquid level sensor on the atmospheric pressure tank to detect the water level inside the tank. If the water level drops below the set value, the water replenishment electric valve will open to replenish water into the expansion tank. The water replenishment electric valve will not be closed until the water level reaches the set upper limit. In terms of exhaust, when high-pressure water in the system enters the atmospheric pressure tank, due to the lower solubility of gas in atmospheric pressure water than in high-pressure water, the excess gas will be released from the water and discharged through the automatic exhaust valve at the top of the tank. The water pump pumps the already treated water back into the system, making the air content in the system water unsaturated. Thus, it can adsorb the free gas in the system again. Through such a cycle process, the exhaust effect is effectively achieved. If the system pressure exceeds the limit value and the water level in the atmospheric pressure tank is at a high level, the safety valve will automatically release pressure to ensure the safety of the system.
