Abstract
The utility model discloses a pump bearing protection device, which comprises a pump shaft and a bearing mounting seat. The pump shaft is supported on the bearing mounting seat through a bearing and provided with a shaft sheath which matches with the bearing mounting seat; the shaft sheath is provided with a water retaining ring with a protection function; and the water retaining ring is integrated with the shaft sheath, thereby preventing the unnecessary waste caused by the use of a material with an excessively large axial diameter and effectively reducing the cost. Because the water retaining ring is made of metal, the medium leaked from the packing box due to the aging failure of the rubber component is effectively prevented from flowing into the bearing cavity along the outer circular surface of the shaft and prevented from flowing into the bearing cavity to damage the bearing, thereby improving the reliability of the pump.
Description
Technical field
The utility model relates to a kind of protective equipment of pump bearing
Background technique
Traditional double-suction centrifugal pump is separately installed with a rubber stop hydrosphere on the pump shaft two ends, enter bearing bore to prevent the medium that axle envelope (stuffing box or mechanical seal) is leaked along the axle outer round surface.But the easy ageing failure of rubber stop hydrosphere, relatively difficulty is changed in the back of losing efficacy, and the medium thrown away of water retaining ring to around splash influence environment on every side.As around other visual plants are arranged, also can constitute a threat to it.It as the patent No. 200710067430.5 protection sheet; comprise lamellar body; the outer ring of lamellar body is weldingly fixed on the outer ring of bearing one end face; there is flange at lamellar body inner ring place; the flange place also is connected with guard circle; guard circle cooperates with inner ring on bearing one end face, and lamellar body inner ring flange and Nei Yanchu are adhesively fixed with the guard circle of the ring-type contact-type of being made by nonmetallic material rubber or plastics.Though this patented technology can play the seal protection effect to bearing, the easy ageing failure of material that guard circle adopts, and change difficulty behind the ageing failure, strengthened the input of cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of medium that effectively stops gland leakage to enter bearing bore, can improve the reliability of pump, the protective equipment of the simple to operate and pump bearing that cost is low.
Goal of the invention of the present utility model is to realize like this, a kind of protective equipment of pump bearing comprises pump shaft and Bearing Installation seat, and pump shaft is bearing on the Bearing Installation seat by bearing, pump shaft is provided with the sheath shaft that matches with the Bearing Installation seat, it is characterized in that: described sheath shaft is provided with water retaining ring.
Described water retaining ring is connected with sheath shaft is integrated.
Described Bearing Installation seat is provided with and is positioned at the outer water retaining cover of sheath shaft.
Be provided with manger board between described Bearing Installation seat and the sheath shaft, this manger board is installed on the end face of Bearing Installation seat.
Described manger board is semi-circular.
Described water retaining ring is a metalwork.
The utility model improves by the protective equipment to existing pump bearing, has been provided with the water retaining ring of protective action on sheath shaft, and water retaining ring is connected with sheath shaft is integrated.This water retaining ring is car system simultaneously on axle not, but connects together with sheath shaft, and sheath shaft is fastening and rotate together with the axis with axle.Thereby can avoid using the excessive material of the diameter of axle and the unnecessary waste that causes, reduce cost effectively, replaced traditional rubber stop hydrosphere.Because what water retaining ring adopted is metallic material, prevent from effectively to enter bearing bore along the axle periphery because of the rubber parts ageing failure causes the medium that axle envelope (stuffing box or mechanical seal) is leaked, avoid medium to enter bearing bore and damage bearing, thereby improved the reliability of pump.
Description of drawings
Accompanying drawing 1 is the section of structure of the utility model most preferred embodiment.
Accompanying drawing 2 is the A place cross-section structure enlarged view of the utility model accompanying drawing 1.
Accompanying drawing 3 is the structural representation of the dash eyebrow plate of the utility model most preferred embodiment.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
With reference to the accompanying drawings 1 and accompanying drawing 2 shown in, the protective equipment of pump bearing of the present utility model, comprise pump shaft 1 Bearing Installation seat 2 and sheath shaft 3, wherein pump shaft 1 is bearing on the Bearing Installation seat 2 by bearing, sheath shaft 3 is arranged on the pump shaft 1 and matches with Bearing Installation seat 2, and sheath shaft 3 is fastenedly connected and synchronous operation with pump shaft 1.On sheath shaft 3, be provided with water retaining ring 4, this water retaining ring 4 and 3 integrated connections of sheath shaft.When the situation of dielectric leakage appears in axle envelope (stuffing box or mechanical seal), water retaining ring 4 stops the medium that leaks from axle envelope (stuffing box or mechanical seal), has avoided medium to leak into Bearing Installation seat 2 internal corrosion bearings
Because of water retaining ring 4 is a metalwork, prolong the life-span of water retaining ring 4 again, strengthened the stability of water retaining ring 4 block medias.This water retaining ring 4 is car system simultaneously on axle 1 not, but connects together with sheath shaft 3, sheath shaft 3 be fastenedly connected with axle 1 and with axle 1 rotation, avoid using the excessive material of the diameter of axle and cause unnecessary waste, reduce cost effectively.Bearing Installation seat 2 is provided with the water retaining cover 5 that is positioned at outside the sheath shaft 3, the medium that axle envelope (stuffing box or mechanical seal) is leaked, stop through water retaining ring 4 can to occur splashing that the medium that water retaining ring 4 splashes out is subjected to stopping of water retaining cover 5, thereby avoid outside pump, splashing and environment around being unlikely to influence.Be provided with manger board 6 between Bearing Installation seat 2 and the sheath shaft 3, this manger board 6 is installed on the end face of Bearing Installation seat 2, and manger board 6 is made as semi-circular as shown in Figure 3.The medium that flows down along the outer wall of Bearing Installation seat 2 to the bottom, has been stopped effectively that the medium of water retaining cover 5 reflections flows in the Bearing Installation seat 2 along the outer wall of bearing support 1 by manger board 6 water conservancy diversion.
