Prevent water hammer and eliminate noise to zero! Case study 5: Acoustic facilities.

The sound of water hammer echoed in the concert hall adjacent to the vacuum pump equipment room, causing a major problem... The introduction of the JVT type vacuum pump solved everything!

The JVT-type drain recovery vacuum pump does not require cooling water and can stably recover high-temperature drains above 90°C. It uses a unique "high-performance hot water jet pump" in the vacuum generation section, allowing it to suck in air, leak steam, drain, and flash steam, so you can use it without worrying about the drain temperature. In the case discussed here, the acoustic facility (concert hall) had a water-sealed vacuum pump in the adjacent pump equipment room, which did not achieve a sufficient vacuum level. As a result, it could not adequately suction the drain, leading to water hammer, which caused significant noise issues in the concert hall... By introducing the JVT-type vacuum pump from Shin-ei Giken, we actively vacuum the recovery pipe to increase drain discharge, preventing any remaining drain and avoiding water hammer. 【Features】 ■ Low noise ■ Customization available ■ No need for supplementary water, ensuring peace of mind during maintenance in extremely cold periods ■ Almost maintenance-free structure that prevents steam from entering the pump As in this case, customization is possible according to customer requests. ★ Currently, we are offering technical documents and the above case study materials!
