Responding to back pressure and flow fluctuations of the drain, drain recovery! Case study 4: Dyeing factory.

Residual drain in the recovery pipe causes water hammer... All problems solved with the introduction of the JVT type vacuum pump!

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, leaking steam, drains, and flash steam, so you can use it without worrying about the drain temperature. In the case of a certain dyeing factory discussed here, they were recovering drains discharged from a roll dryer using pneumatic transport. However, due to changes in the operating conditions of the roll dryer, fluctuations in back pressure and flow rate led to poor return of the recovered drains, causing temperature unevenness and resulting in poor drying of the fabric... By introducing the JVT-type vacuum pump from Shin-ei Giken, the recovery pipe was put under vacuum to respond to fluctuations in back pressure and flow rate, preventing drain residue and achieving water hammer prevention. 【Features】 ■ Low noise ■ Customization available ■ No need for supplementary water, ensuring peace of mind during maintenance in severe cold periods ■ Structure prevents steam from entering the pump, making it almost maintenance-free As in this case, customization is possible according to customer requests. ★ Currently, we are offering technical materials and the above case study materials together!
