Abstract
The invention discloses a mechanical sealing device of a heating network circulating pump without flushing water. The mechanical sealing device comprises a movable ring seat, rubber gaskets, a spring, an adjusting pad, a movable ring, a static ring, a movable ring anti-rotating pin, a shaft sleeve locking wire, a fixed pressing cover and a static ring seat, wherein the movable ring seat is of a T structure, and the rubber gasket I is installed on the inner wall of the left end of the movable ring seat; the movable ring is installed on the right side of the movable ring seat and is connected with the movable ring anti-rotating pin on the movable ring seat; the rubber gasket II is arranged between the movable ring and the movable ring seat; the static ring is closely installed on the right side of the movable ring and is connected with the static ring seat by virtue of the rubber gasket III; the static ring seat sleeves the movable ring seat. Both the movable ring and the static ring are made of high-hardness wear-resistant silicon carbide, so that the wear of impurities in a working medium on the movable ring and the static ring is eliminated. A mechanical sealing elastic element is isolated from the working medium, and the movable ring and the static ring have the advantages of high hardness and high wear resistance.
Description
Technical field
The present invention relates to water pump mechanical seal technical field, specifically pumps for hot water supply net without flushing water machinery
Sealing device.
Background technology
Our factory heat supply heat supply network circulation is the hugest, in work progress, the most generally there is local heat
The construction quality management and control of power company is not tight, causes in tubing more containing the foreign material such as silt and welding slag, these
Tiny foreign material filter screen in heat supply network circulation filters again incessantly, owing to system is the hugest, again can not
Rinsed system cleaning down by water, the mechanical seal at pumps for hot water supply net can only be used to inject high pressure
Cleaning flushing water stops foreign material, it is ensured that the service life of mechanical seal.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and provide a kind of pumps for hot water supply net without flushing water
Mechanically-sealing apparatus, cancels the flushing water of mechanical seal, and the service life of mechanical seal to be ensured is not
Reduce.
The present invention adopts the following technical scheme that realization for achieving the above object:
Pumps for hot water supply net without flushing water mechanically-sealing apparatus, including: rotating seat, cushion rubber, spring, adjusting pad,
Rotating ring, stationary ring, rotating ring stop pin, axle sleeve lock silk, stationary gland, stationary seat, described rotating seat is T
Type structure, the inwall of its left end is provided with cushion rubber I；Described rotating ring is arranged on the right side of rotating seat also
It is connected with rotating ring stop pin thereon；Cushion rubber II it is provided with between described rotating ring and rotating seat；Described is quiet
Ring is arranged on the right side of rotating ring closely, and is connected with stationary seat by cushion rubber III；Described stationary ring cover for seat
It is contained on rotating seat；Described stationary gland sequentially passes through spring, adjusting pad is sleeved on rotating seat and stationary ring
Seat connects, and is fixed by axle sleeve lock silk.
Aforesaid pumps for hot water supply net all uses carbonization without flushing water mechanically-sealing apparatus, described rotating ring and stationary ring
Silicon is made.
The material of rotating ring and stationary ring all uses the carborundum of high hardness wear-resisting, eliminates the impurity in working media
Abrasion to dynamic and static ring.Mechanical seal flexible member is isolated with working media, dynamic and static ring material hardness height,
Wearability is high.
