Abstract
The utility model discloses a non - drive end bearing cooling device of vapour front pump, it includes the cooling water cover of fixed connection on the bearing cover outer wall, the cooling water is covered and is equipped with water inlet and delivery port. The utility model discloses a set up the cooling water cover to the technical scheme simple and practical of the non - drive end bearing of vapour front pump cooling at the non - drive end bearing cover of vapour front pump, it is effective feasible, both avoided the bearing temperature to rise to the harm of equipment, improved the reliability of equipment, solve prior art through closed circulation's mode again and through the water waste that leads to the fact in the trickle cooling of bearing roof portion and the problem of factory's environment difference, be suitable for the popularization.
Description
Technical field:
The utility model relates to bearing cooler, relates in particular to a kind of vapour front pump anti-drive end axleHold cooling device.
Background technology:
Thermal power plant working medium circulation be by pump handle feed water pressurization after send into boiler, at boilerMiddle endothermic disintergration is high temperature and high pressure steam, and steam enters the rotation of steam turbine promotion steam turbine generator and doesMerit, is converted into electric energy by mechanical energy, does the steam completing and enters condenser and condense into water, processAfter water pump pressurizations at different levels, again enter boiler, so repeatedly, form the circulation of working medium. Water pump existsIn thermal power plant effect very large, its reliability directly has influence on the safe operation in power plant, vapourThe equipment that front pump boosts as feed pump, improves to avoid feedwater to pump into entrance of water-supplying pump pressureMouth impeller and runner cavitation; Vapour front pump, at actual motion middle (center) bearing temperature drift, affects unit peaceRow for the national games. Thermal power plant adopts conventionally at vapour front pump bearing chamber top trickle at present, and water is from bearing chamberThe method that the heat under overhead stream, bearing being produced is taken away is pump bearing cooling before vapour, this methodAlthough can play a role to bearing cooling, act on limited. In addition the method,Not only affect the environmental sanitation of plant area, and can cause the significant wastage of water resource, be unfavorable for electricityThe construction that civilises of factory.
Utility model content:
The purpose of this utility model is to provide a kind of vapour front pump non-driven-end bearing cooling device.
The utility model is implemented by following technical scheme: a kind of vapour front pump non-driven-end bearing is coolingDevice, it comprises the cooling water cover being fixedly connected on bearing gland outer wall, described cooling water coverBe provided with water inlet and delivery port, cooling water enters described cooling water cover inside from described water inletCooling water cavity, absorb produce and pass to described bearing gland through bearing heat after, from describedDelivery port is discharged, and forms closed cycle with this, reaches axle described in described vapour front pump anti-drive endThat holds is cooling.
Further, described cooling water cover inside is fixed with dividing plate, and described dividing plate is by described coldBut hydroecium separate but do not cut off, on the intake antrum of described dividing plate both sides and water chamber, be respectively equipped with intoThe mouth of a river and delivery port, for increasing the time of contact of cooling water and described bearing gland.
Further, described cooling water cover inside is fixed with snakelike dividing plate, described dividing plate everyThe inlet and outlet of the cooling water cavity of opening is respectively equipped with water inlet and delivery port.
Advantage of the present utility model:
1, the utility model adopts, at vapour front pump non-driven-end bearing gland, cooling water cover pair is setThe technical scheme of vapour front pump non-driven-end bearing cooling is simple and practical, effective and feasible, has avoided axleHold the infringement that temperature raises to equipment, improved the reliability of equipment.
2, the utility model has solved prior art by bearing by the mode of closed cycleTop, chamber trickle the lower the temperature water resource waste and the poor problem of plant environment that cause, be suitable for promoting.
3, the utility model adopts snakelike dividing plate that cooling water cavity is separated, and has increased cooling waterWith the time of contact of bearing gland, improve heat exchange efficiency, save cooling water amount.
Brief description of the drawings:
Fig. 1 is 1 one kinds of vapour front pump non-driven-end bearing cooling device axonometric drawings of embodiment;
Fig. 2 is 1 one kinds of vapour front pump non-driven-end bearing cooling device front views of embodiment;
Fig. 3 is the A-A cutaway view of Fig. 2.
In figure: bearing gland 1, cooling water cover 2, dividing plate 3, cooling water cavity 4, water inlet 5,Delivery port 6.
Detailed description of the invention:
Embodiment 1: a kind of vapour front pump non-driven-end bearing cooling device, it comprises and being fixedly connected withCooling water cover 2 on bearing gland 1 outer wall, cooling water cover 2 inside are fixed with snakelikeDividing plate 3, for increasing the time of contact of cooling water and bearing gland 1; It is cold that dividing plate 3 separatesBut the inlet and outlet of water cavity 4 is respectively equipped with water inlet 5 and delivery port 6, and cooling water is from enteringThe mouth of a river 5 enters the cooling water cavity 4 of cooling water cover 2 inside, absorbs and produces and pass to axle through bearingAfter the heat of pressure cap 1, discharge from delivery port 6, form closed cycle with this, reach vapourFront pump non-driven-end bearing cooling.
