In today’s work, I replaced the filter cartridge of a stainless steel outdoor filter for a customer. This filter is widely used in sand bucket filters. Below, I will provide a detailed explanation of the steps involved in replacing the filter cartridge and important considerations to ensure a smooth replacement process.
Step 1: Remove the cleaning head
Firstly, we need to remove the cleaning head from the filter. This can be done by unscrewing the locking nut of the cleaning head. Make sure to close the inlet valve before removing the cleaning head to prevent water impact.
Step 2: Flush the old sand and activated carbon
Lay the stainless steel body flat and connect a water hose to the inside of the body. Open the inlet valve and insert one end of the water hose into the body while ensuring that the other end is directed to a suitable drainage location. This will allow the water flow to flush out the old sand and activated carbon, thoroughly removing impurities from the body. It is recommended to use an appropriate water flow intensity to avoid unnecessary damage to the body and surrounding environment.
在今天的工作中，我为客户更换了一款白钢户外过滤器的滤芯，该过滤器被广泛应用于沙桶过滤器。下面将详细介绍滤芯更换的步骤以及需要注意的事项，确保更换过程顺利进行。
第一步：卸下清洗头
首先，我们需要卸下过滤器上的清洗头。这可以通过拧下清洗头旋转锁定螺母来实现。请确保在卸下清洗头之前关闭进水阀门，以防止水流冲击。
第二步：冲洗旧的沙石及活性炭
将白钢机身放倒，并引一条水管连接到白钢机身内部。打开进水阀门，将水管的一端插入机身内，并确保另一端排放到合适的排水位置。此时，水流将会冲刷掉旧的沙石和活性炭，确保机身内部的杂质被完全清除。建议使用适宜的水流强度，以避免对机身和周围环境造成不必要的损坏。
Step 3: Prepare to install the new filter cartridge
Prepare the new filter cartridge. The sand filter media is divided into three types based on particle size: 2.4-4.8mm, 1.2-2.4mm, and 0.6-1.2mm. Additionally, 8x30mech is a commonly used activated carbon model. Select the appropriate sand and activated carbon for filling based on filtration requirements and manufacturer recommendations. During the filling process, you can refer to the filter’s user manual or the manufacturer’s guidelines.
Step 4: Check for leaks and clean the area
After installing the new filter cartridge, check for any leaks in the filter. Open the inlet valve and observe the connections and sealing performance of the filter to ensure no water leakage. If any leaks are detected, recheck the connections and ensure proper installation of sealing rings or gaskets.
Finally, clean the area. During the process of replacing the filter cartridge, there may be some dirty water that wets the ground. It is important to clean the work area thoroughly.
By following the above steps, you can successfully replace the filter cartridge of the stainless steel outdoor filter and ensure the proper functioning of the filter. When performing any maintenance and replacement operations, always follow the manufacturer’s guidelines and operation manual to ensure proper and safe procedures are followed.
第三步：准备装入新的滤芯
准备好新的滤芯。沙石滤料根据粒径分为3种：2.4-4.8mm、1.2-2.4mm、0.6-1.2mm。另外，8x30mech是一种常用的活性炭型号。根据过滤要求和厂商推荐，选择适当的沙石和活性炭进行装填。在装填时，可以参考过滤器的使用手册或厂商提供的指导。
第四步：检查漏水和清洗地面
安装好新的滤芯后，检查过滤器是否漏水。打开进水阀门，观察过滤器的连接处和密封性能，确保没有任何水漏出。如果发现漏水问题，请重新检查连接，并确保密封圈或密封胶垫正确安装。
最后，进行地面清洗。在更换滤芯的过程中，可能会有些肮脏水流淋湿地面。请务必清洁工作区域。
通过以上步骤，您可以成功更换白钢户外过滤器的滤芯，并保证过滤器的正常运行。在进行任何维护和更换操作时，请务必遵循厂商提供的指南和操作手册，确保操作正确、安全。
