一种双端面机械密封自身压力增压系统
摘要：
本发明公开了一种双端面机械密封自身压力增压系统，其结构包括出水口、固定法兰、泵体、增压装置、电机转子、吊环、防护罩、水泵、固定基座、底座、加固件、控制阀、紧固件，所述出水口与固定法兰相连接，所述泵体与增压装置相连接，所述增压装置由进水口、水管、负压室、平衡固定盘、紧固支架组成，所述进水口与水管相连接，所述水管与负压室相连接，所述紧固件与底座固定连接。本发明设有增压装置，能够克服系统的阻力，在循环泵流量不变的情况下，循环泵的扬程降低，则循环泵所配电机功率将大幅下降，从而达到节约设备运行电费的目的。
摘要（英）：

The invention discloses a self pressure boosting system for double mechanical seal. The self pressure boosting system comprises a water outlet, a fixed flange, a pump body, a pressure boosting device,a motor rotor, a flying ring, a protective cover, a water pump, a fixed pedestal, a base, a reinforcing piece, a control valve and a fastening piece, wherein the water outlet is connected with the fixed flange, and the pump body is connected with the pressure boosting device. The pressure boosting device is composed of a water inlet, a water pipe, a negative pressure chamber, a balanced fixed disc and a fastening support. The water inlet is connected with the water pipe, the water pipe is connected with the negative pressure chamber, and the fastening piece is fixedly connected with the base.The pressure boosting is arranged and can overcome the resistance of the system. Under the condition that the flow of a circulating pump does not change, the lift of the circulating pump is reduced,the power of a motor matched with the circulating pump is greatly reduced, and therefore the purpose of saving the equipment operating charge is achieved.
