Abstract
The utility model discloses an abrasion resisting type efficient mechanical sealing structure of a marine pump. The abrasion resisting type efficient mechanical sealing structure of the marine pump comprises a press cover fixed with a pump body and sealed, a rotating ring seat sleeved on a shaft sleeve and a stationary seal ring sleeved on the shaft sleeve and limited on the press cover in peripheral mode. The rotating ring seat is tightly matched with a rotating seal ring, the tail portion of the stationary seal ring is provide with a pressing spring, the end face of the head portion of the stationary seal ring is provided with a ring groove, an abrasion resisting sealing piece capable of rotating freely is arranged in the ring groove, a sealing face of the rotating seal ring is attached with the abrasion resisting sealing piece, and an O-type sealing ring is arranged between the rotating ring seat and the shaft sleeve and the rotating seal ring respectively. The abrasion resisting type efficient mechanical sealing structure of the marine pump is simple in structure and convenient to mount and maintain; adopts the design that the abrasion resisting sealing piece is arranged between the stationary seal ring and the rotating seal ring, and the O-type sealing ring is arranged between the rotating ring seat and the shaft sleeve and the rotating seal ring respectively; effectively improves abrasion resisting performance of the rotating seal ring, prolongs service life of the rotating seal ring, and guarantees sealing performance of the sealing structure of the marine pump.
Description
Technical field
The utility model relates to a kind of mechanical seal structure, is specially a kind of wear-resisting type highly effective mechanically-sealing structure of marine pump.
Background technique
In order to guarantee normal navigation or the mooring of ship, the life of satisfying crewman and passenger is essential, guarantee boats and ships stationarity, unsinkability, livability, Security, vitality and complete some special mission etc., all needing to have marine pump some, that can play respective action.Therefore marine pump is one of mechanical device important in ship machinery, and in total cost, the marine pump of common ship accounts for the 4%-8% of full ship equipment expense.Yet marine pump in use, because ship position has mobility, waving and vibrating all when ship moves can impact the sealability of marine pump, marine pump is waved for a long time, vibration etc. affects, make easily that in the sealing configuration of marine pump, moving sealing ring is subjected to the axle sleeve serious wear, make shorten the working life of moving sealing ring, the sealing effect of sealing configuration descends, and therefore needs frequently marine pump to be safeguarded.
The model utility content
The purpose of this utility model is to provide a kind of wear-resisting type highly effective mechanically-sealing structure of marine pump, in prior art, traditional marine pump is waved for a long time to solve, vibration etc. affects, make easily that in the sealing configuration of marine pump, moving sealing ring is subjected to the axle sleeve serious wear, make shorten the working life of moving sealing ring, the sealing effect of sealing configuration descends, thereby the problem that need to safeguard marine pump frequently.
For achieving the above object, the technical solution adopted in the utility model is:
a kind of wear-resisting type highly effective mechanically-sealing structure of marine pump, comprise the gland of fixing and sealing with the pump housing, be socketed in the rotating seat on axle sleeve, be socketed on axle sleeve and circumferential spacing stationary seal ring on gland, it is characterized in that: described rotating seat tightens is furnished with moving sealing ring, described stationary seal ring afterbody is provided with holddown spring, described stationary seal ring head end is provided with annular groove, wear-resistant seal sheet free to rotate is installed in described annular groove, the sealing surface of described moving sealing ring and wear-resistant seal sheet fit, described rotating seat respectively with axle sleeve, be provided with the O RunddichtringO between moving sealing ring.
The wear-resisting type highly effective mechanically-sealing structure of described a kind of marine pump is characterized in that: be provided with stuffing box packing between described gland and axle sleeve.
The beneficial effects of the utility model are:
The utility model is simple in structure, convenient for installation and maintenance, employing arranges the design of wear-resistant seal sheet between stationary seal ring and moving sealing ring, and the design that the O RunddichtringO is set respectively between rotating seat and axle sleeve, moving sealing ring, effectively promoted the wear-resisting property of moving sealing ring, extend the working life of moving sealing ring, guaranteed the sealability of the sealing configuration of marine pump.
