Abstract
The utility model discloses an efficient mechanical sealing structure of a marine pump. The 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 circumferential mode. The rotating ring seat is provided with a rotating seal ring in interference fit mode, the head portion of the stationary seal ring is attached with the rotating seal ring, and the tail portion of the stationary seal ring is provided with a pressing spring. O-type sealing rings are respectively arranged between the rotating seal ring seat and the shaft sleeve and between the rotating ring seat and the rotating seal ring, an inner hole of the rotating seal ring is provided with a protrusion, and the shaft sleeve is provided with a radial annular groove matched with the protrusion on the rotating seal ring inner hole. The efficient mechanical sealing structure of the marine pump is simple in structure and convenient to mount and maintain, 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 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 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 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 head and moving sealing ring are fitted, described stationary seal ring afterbody is provided with holddown spring, described rotating seat respectively with axle sleeve, be provided with the O RunddichtringO between moving sealing ring, the endoporus of described moving sealing ring is provided with projection, described axle sleeve is provided with the radial ringed groove that matches with projection on the moving sealing ring endoporus.
The 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, adopt the design that projection, groove match is set between moving sealing ring and axle sleeve outer wall, 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.
