3.2G 6G 11G 20G 28G Pure Water Machine Pressure Barrel Water Purifier Water Storage Tank Accessories

Description :

  The pressure tank is the core water storage component in the reverse osmosis pure water machine system, mainly solving the contradiction between slow water production speed and peak water demand. It utilizes the principle of internal airbag pressure to store and pressurize purified pure water, ensuring stable and continuous water flow when users turn on the faucet. This series of products covers various specifications from 3.2G to 20G, widely applicable to household desktop, kitchen, and small commercial water purification equipment. As a key component of water purifiers, the performance of the pressure tank directly affects the overall water output experience and the operating frequency of the water pump, and is a fundamental component for ensuring the efficient operation of the water purification system.

  This series of pressure tanks is strictly manufactured in accordance with the national drinking water hygiene standards and has formal water certification to ensure water safety. The outer shell is usually made of high-strength steel or food grade plastic material, while the inner liner uses food grade rubber airbags that comply with FDA standards, effectively isolating contact between air and water and preventing secondary pollution. The common working pressure range is between 0.14-0.28MPa, and the pre charge pressure is usually 0.05-0.07MPa. The interface threads are mostly standard American style teeth, compatible with the vast majority of reverse osmosis membrane shells and faucets on the market. The product undergoes strict air tightness and pressure resistance tests to ensure that it does not leak or leak under long-term high-pressure environments, and its physical properties are stable and reliable.

  The selection should be based on the flux of the water purifier and the household water consumption. The 3.2G and 6G specifications are compact in size, suitable for kitchen installations with limited space or for single or double person households; The 11G, 20G, and 28G specifications have large water storage capacity, making them suitable for multi population households or scenarios with high requirements for instantaneous water consumption. If the flux of the water purifier is small (such as 50G-75G), it can be matched with a 3.2G or 6G pressure tank to meet daily needs; If using a high flux machine or wanting to reduce the number of water pump starts, it is recommended to choose the 11G or 20G model. It should be noted that pressure drums are not suitable for direct heating or freezing environments, and it is necessary to confirm whether the installation space can accommodate the corresponding volume of tank to avoid conflicts with other pipelines.

  During installation, ensure that the inlet and outlet directions are correct. It is recommended to install a one-way valve at the inlet end to prevent backflow of water flow. In daily use, it is recommended to check the pre inflation pressure once a year. If the water flow decreases or the water flow is intermittent, it may be due to a damaged airbag or insufficient air pressure, and it needs to be replenished or replaced in a timely manner. Avoid exposing the pressure tank to direct sunlight or high temperatures to prevent aging of the casing or bacterial growth inside. Regularly emptying the accumulated water in the bucket and cleaning and disinfecting it can extend its service life and maintain fresh water quality. If the barrel is found to be deformed, severely corroded, or leaking from the interface, it should be immediately stopped from use and replaced with new parts to ensure drinking water safety.
