Abstract
The utility model provides a counterflow round cooling tower water sprayer positioner, which consists of a water sprayer upright shaft, a water sprayer pipe, a water sprayer pull rope and a bottom bearing of the water sprayer. In particular, the top of the upright shaft of the water sprayer is provided with a top bearing of the water sprayer, and the bearing is connected with the cavity through a fixing component. The utility model decreases the radial jump of the upright shaft of the water sprayer, releases the bearing abrasion, reduces the repairing and maintaining time, and greatly increases the continuously working time of the cooling tower.
Description
Technical field:
The utility model relates to technical field of heat exchange, particularly the location technology of cooling tower water distributor in the hot swapping.
Background technology:
Cooling tower is in the open atmosphere environment, the recirculated water of equipment such as central air-conditioning, refrigerator is used the equipment that physical effects such as heat exchange, liquid gasification absorption heat of gasification are cooled off.Reverse-flow circular cooling tower is widely used in each department of national economy.The operation principle of cooling tower is: axial flow blower drives outside dry air and enters cavity by the cooling tower bottom, and when flowing through fin, the droplet that sprays out also free-falling with water distribution system meets.Because the contact area of air and water is very big, on the one hand, the heat exchange effect is remarkable, on the other hand, when aqueous vapor turns to steam, absorbs a large amount of heat of gasification, thereby water temperature is reduced.Cooled recirculated water is collected at the bottom of by basin and is recycled through being pumped to thermal source.
Two assemblies of making circular motion in the reverse-flow circular cooling tower.The one, axial flow blower and blade.Driven by motor decelerator driving shaft flow fan blade rotation.Decelerator is many with gear or belt decelerator.Decelerator is industrial matured product.Maintain properly, fault rate is extremely low; The 2nd, sprinkler system, sprinkler system is commonly called as water distributor, by hydraulic drives.Heat-exchanger pump to be cooled is delivered to water distributor, ejects with certain initial velocity, according to newton's the 3rd law, at this moment a reaction force acts is arranged in water distributor, promotes whole water distributor backwards rotation (similar jet engine), realizes evenly broadcasting water.
In on-the-spot the use, following problem often appears.Cooling tower is after a period of time uses, and the wearing and tearing of water distributor bottom bearing have formed horn mouth, and the axle center of water distributor does not overlap with its revolution axle center, and at this moment a large amount of hot water to be cooled can leak from the water distributor bottom and go out; It is inhomogeneous that whole water distributor is broadcast water, and the cooling tower cooling effect is poor.
Cooling tower generally is to turn round continuously and do not have the backup unit; Maintenance downtime outside the plan is many, and maintenance cost is big.
Summary of the invention:
The technical problem that the utility model solved is the deficiency at above technology, a solution is provided, can eliminate or reduce the circular runout of cooling tower water distributor vertical shaft, reduce the wearing and tearing of water distributor bottom bearing,, increase the cooling tower stream time greatly to reduce maintenance number of times and time.
The utility model technical problem can realize by the following method:
A kind of reverse-flow circular cooling tower water distributor positioner, comprise water distributor vertical shaft 2, broadcast water pipe 3, water distributor drag-line 4, water distributor bottom bearing 5, standpipe 6 and drag-line cover 7, be provided with the water distributor apical axis at the top of water distributor vertical shaft 1 and hold 8, the water distributor apical axis holds by fixture 9 and cavity 1 and joins.Fixture 9 can be symmetrically arranged more than three or three, can be to rigidly fix part, and also can be flexible attachment.
The utility model technology beneficial effect is, the design that the water distributor apical axis holds becomes single-ended bearing and orientates both-end bearing location as, reduced radially wobbling of water distributor vertical shaft greatly, reduce bearing wear, reduced maintenance maintenance number of times, increased the cooling tower stream time greatly.
Description of drawings:
Fig. 1 is the utility model prior art cooling tower part schematic diagram;
Fig. 2 is the utility model structure division schematic diagram.
The specific implementation method:
Reverse-flow circular cooling tower water distributor positioner, comprise water distributor vertical shaft 2, water distributor pipe 3, water distributor drag-line 4, water distributor bottom bearing 5, standpipe 6 and drag-line cover 7, establish a water distributor apical axis at the top of water distributor vertical shaft 2 and hold 8, the water distributor apical axis holds 8 and joins by fixture 9 and cavity 1.Described fixture 9 can be symmetrically arranged more than three or three, can be to rigidly fix part, and also can be flexible attachment.
Here broadcasting the water pipe sprinkler system with four is example, big-and-middle-sized cooling tower greater number commonly used broadcast the water pipe sprinkler system.
On the top of vertical shaft 2, drag-line overlaps 7 tops and the water distributor apical axis is housed holds 8, and an end of fixture 9 and apical axis hold 8 and join, and the other end draws mutually with cavity 1.
Boring 11 fixing points on the fiberglass cavity 1 as pull rope, totally four of these fixing holes, along fiberglass cavity circumference uniform distribution, fixed form can adopt stainless steel bolt to connect, bolt underlay stainless steel gasket, and the centre of pull rope installs wire tensioner 10 (a kind of standard component additional, be usually used in the electric pole pull rope), adjustment bolt on the wire tensioner 10 is the adjustable link of pull rope length, adjusts the length of four pull ropes, and the center of gravity of sprinkler system is overlapped with gyroaxis.
Installation steps:
Utilize the prolongation of former sprinkler system vertical rod, processing axle and axle sleeve on lathe.
Make and install bearing shell, drag rope and wire tensioner are installed, inject lubricant grease.
Accurately adjust four along the bolt on the uniform wire tensioner of fiberglass cavity all around, the sprinkler system center of gravity is overlapped with axis of rotation.
The setting stick car, observe the water distributor running whether smooth and easy, have or not and give up the idea, if work well, test run can power on.
