Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] An embodiment of the present invention provides a mechanical seal device, which is suitable for installation on a rotating shaft. In this embodiment, the mechanical seal device can be applied to an electric deep well pump, wherein the liquid medium pumped by the electric deep well pump It is often a flammable and explosive liquid medium, such as liquefied petroleum gas, liquefied natural gas, etc., through the mechanical seal device provided by the embodiment of the present invention, the heat generated by the mechanical seal component can be transmitted in time, avoiding the temperature of the mechanical seal component The rise causes the failure of the mechanical seal components, resulting in the leakage of flammable and explos...

Abstract

The invention discloses a mechanical sealing device and belongs to the field of sealing devices. The mechanical sealing device comprises a mechanical sealing assembly arranged on a rotation shaft in a sleeving mode, a first sealing gland, a second sealing gland, a sealing base, a pumping ring and a fan, wherein the first sealing gland and the second sealing gland are arranged on the rotation shaft in a sleeving mode and arranged on the two sides of the mechanical sealing assembly, the sealing base is arranged between the first sealing gland and the second sealing gland, the pumping ring is fixedly arranged on a movable ring of the mechanical sealing assembly in a sleeving mode, and the fan is arranged on the rotation shaft in a sleeving mode and arranged spaced from the mechanical sealing assembly. An annular sealing cavity is formed among the mechanical sealing assembly, the first sealing gland, the second sealing gland and the sealing base. The pumping ring is located in the sealing cavity. The sealing cavity is internally provided with a liquid medium and a heat conduction block. By means of rotation of the pumping ring, the liquid medium circularly flows in the sealing cavity, and therefore heat produced by working of the mechanical sealing assembly is fully transmitted to the heat conduction block and dissipated through the fan, and then the heat dissipating and cooling of the mechanical sealing assembly are achieved.

Description

technical field [0001] The invention relates to the field of sealing devices, in particular to a mechanical sealing device. Background technique [0002] A mechanical seal refers to a device that prevents liquid leakage by at least one pair of end faces perpendicular to the rotating shaft that are held together and relatively slid under the action of liquid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal. Mechanical seal components generally include: moving ring, static ring, auxiliary seal, and elastic compensation mechanism. During operation, there is relative motion between the moving ring and the static ring. Under the joint action of the liquid medium pressure and the elastic force of the elastic compensation mechanism, the dynamic The end faces of the ring and the static ring are closely fitted and a liquid film is formed between the two ends, thereby achieving a seal. [0003] During the worki...
