The invention discloses a double-channel fully-enclosed internal circulation mechanical sealing system, which relates to the technical field of mechanical dynamic sealing, including a mechanical sealing device, a liquid leakage collection system, a liquid storage tank, a fluid circuit and a one-way valve. The mechanical sealing device is a double The channel dynamic sealing device is equipped with a leakage diversion channel in the device. At the same time, the leakage collection system is an integrated system of leakage collection, detection and recovery. The water pump is triggered to start and stop through the upper and lower liquid level switches, and the counter and system The control circuit records the number of starts and running time of the pump, so it has the functions of collecting leakage, recording the leakage and reintroducing the leakage into the storage tank; the one-way valve can realize the output of the leakage collection system to the storage tank, The fluid in the liquid storage tank will not flow back to the leakage collection system, thus ensuring that the system can also be applied to a closed system with system back pressure, realizing the dual-channel fluid rotary transmission without leakage outside the system, and zero external leakage. leakage.
Description
technical field [0001] The invention relates to the technical field of mechanical dynamic sealing, in particular to a double-channel fully enclosed internal circulation mechanical sealing system. Background technique [0002] A mechanical seal refers to a device that prevents fluid leakage by at least one pair of end faces perpendicular to the axis of rotation, under the action of fluid pressure, compensation mechanism (or magnetic force), and the cooperation of auxiliary seals to keep fit and slide relative to each other. Ceramic sealing ring is the most critical part in mechanical seal, but because its material is ceramic, there are problems of brittleness and large difference in thermal expansion coefficient and metal. Therefore, the reliability is high and the service life is long when the environment is relatively stable—no vibration and shock, and the temperature of the working environment does not change much. However, in the environment of vibration shock and temper...
