Abstract

The invention discloses a novel shaft sealing device which comprises a pedestal, a shock absorber, an alarm device, a controller, a gas hole and a guide sleeve, wherein a silencer is arranged at one side of the pedestal; a throttle valve is arranged above the controller; an energy conversion device is arranged at one side of the shock absorber; a cylinder sleeve is arranged below the energy conversion device; a fixed base is arranged at one side of the alarm device; a supporting base is arranged below the alarm device; and a sensor is arranged at one side of the gas hole. According to the novel shaft sealing device disclosed by the invention, the silencer and the shock absorber are arranged inside the device, so that the device works and operates more stably; the energy conversion device is arranged at one side of the shock absorber, so that kinetic energy generated by motion of the device is stored in the energy conversion device; in case of insufficient power supply, the energy conversion device is started, so that the sealing device continuously operates; and the alarm device is arranged above the supporting base, so that connection with a power supply is automatically interrupted when the device has faults during an operation period.

Description

technical field [0001] The invention relates to the technical field of sealing devices, in particular to a novel shaft sealing device. Background technique [0002] In the past, we only paid attention to the elimination of visible fluid leakage, but did not pay attention to the control of invisible volatiles, which would cause environmental pollution and be dangerous to devices and people. Foreign countries such as the Sealing Technology Committee of the American Society of Tribology and the Society of Lubrication Engineers have formulated SP-30, SP-32 and SP-33 guidelines for controlling volatile emissions of rotating machinery, compressors and screw systems with mechanical seals. SP-30 is implemented in three phases. It clearly stipulates the definition of blocking fluid and buffer fluid, and clarifies the wrong and confusing concepts. A blocking fluid is a fluid that is introduced between the double seals to completely block leakage of the process fluid to the surroundi...
