Mechanical sealing device for slurry pump

Abstract

The invention belongs to the field of mechanical sealing and particularly relates to a mechanical sealing device for a slurry pump. The mechanical sealing device for the slurry pump comprises an internal seal and an external seal. The mechanical sealing device is characterized in that the internal seal comprises an internal movable ring, an internal fixed ring, an O-shaped ring, a cushioning type drive pin, an elastic shaft retaining ring, a spring push ring and a spring and used for sealing of sealing liquid and a medium; the external seal comprises an external movable ring, an external fixed ring, an O-shaped ring, a cushioning type drive pin, a push ring, a spring and an anti-disengaging positioning clamping ring and used for sealing of sealing liquid; and the internal movable ring and the internal fixed ring are used for sealing the medium, the outer movable ring and the outer fixed ring are used for sealing the liquid, and clean sealing face lubricating and heat dissipation are provided. The mechanical sealing device for the slurry pump has the beneficial effects of being perfect in performance, low in cost, safe and reliable, long in service life and easy to damage. By the adoption of the mechanical sealing device for the slurry pump, the problems that a traditional mechanical seal for a desulfurization pump is easy to damage and short in service life can be completely solved. It is proved by the practice that the device can be used for production and scientific experiments in the industries of power, industrial and mining enterprises and the like, and the device is completely feasible in terms of technology, economy and environmental protection.

Description
