Abstract
The utility model discloses a closed cooling tower with a pressure stabilizing device. The closed cooling tower with the pressure stabilizing device comprises a cooling tower body, a spraying pipe is arranged in the cooling tower body, and is connected with a water pump, and a damping hole plate is arranged at the position, close to the outlet of the water pump, of the spraying pipe. Rubber pads are arranged on the two sides of the damping hole plate respectively, and the rubber pads on the two sides of the damping hole plate are clamped and fixed together through a flange plate on the spraying pipe. According to the closed cooling tower with the pressure stabilizing device, the damping hole plate is arranged to replace a valve to adjust the water discharge pressure of the water pump, mounting is convenient, mounting space is not increased, cost is saved, and the closed cooling tower is simple in adjustment, convenient to use and easy to popularize.
Description
Technical field
The utility model relates to a kind of cooling tower, relates in particular to a kind of closed cooling tower with stable-pressure device.
Background technique
Cooling tower is provided with a spraying tube and water pump, and the lift of water pump is normal between a setting district, has gone out this interval pump with regard to cisco unity malfunction.Particularly, lower than the lift of pump operation, will cause the load of pump to strengthen, even burn out motor.
Often lower than lift of pump, therefore existing spray delivery side of pump has generally been installed a set of valve due to the tower height of cooling tower.The user regulates the outlet pressure of spray pump by controlling opening of valve, if regulating valve is improper in use, just there will be circuit tripping operation and burn-down of electric motor phenomenon.And due to the restriction in space, valve is being installed also more difficultly, cost is also higher.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of closed cooling tower with stable-pressure device, and not only convenient the installation, cost-saving, and regulates simple, easy to use.
The utility model is to solve the problems of the technologies described above the technological scheme adopted to be to provide a kind of closed cooling tower with stable-pressure device, comprise cooling column body, in described cooling column body, be provided with spraying tube, described spraying tube is connected with water pump, wherein, on described spraying tube, the outlet port near water pump is provided with the damping orifice plate.
The above-mentioned closed cooling tower with stable-pressure device, wherein, the both sides of described damping orifice plate are respectively equipped with rubber pad, and the both sides rubber pad is fixedly clamped together by the flange plate on spraying tube.
The above-mentioned closed cooling tower with stable-pressure device, wherein, the top of described cooling column body also is provided with blower fan.
The utility model contrast prior art has following beneficial effect: the closed cooling tower with stable-pressure device that the utility model provides, by being set, the damping orifice plate replace valve to regulate the discharge pressure of water pump, not only convenient installation, do not increase installing space, saved cost, and regulate simply, easy to use, be easy to promote.

Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is the closed cooling tower structural representation that the utlity model has stable-pressure device; Fig. 2 is the local enlarged diagram in A place in Fig. 1.
Refer to Fig. 1 and Fig. 2, the closed cooling tower with stable-pressure device that the utility model provides comprises cooling column body 1, is provided with spraying tube 3 in described cooling column body 1, and described spraying tube 3 is connected with water pump 2, wherein, on described spraying tube 3, the outlet port near water pump 2 is provided with damping orifice plate 4.
The closed cooling tower with stable-pressure device that the utility model provides, replace valve by damping orifice plate 4 is set, and saved cost; Damping orifice plate 4 is arranged on the outlet port of water pump 2, stablizes self working pressure of pump.According to flow and the pressure that water needs, calculate the pore size of damping orifice plate 4.Aperture is large, does not reach the effect of damping, and self pressure of pump does not reach requirement, still can produce pump motor load phenomenon bigger than normal.Aperture is little, and the underfed of water affects the cooling performance of cooling tower.The spray pressure design of cooling tower is a fixing value, with damping plate, sets the control that just can complete pressure with the coupling of water pump.In case after setting the aperture of damping orifice plate 4, just need not regulate pressure, easy to use, reduce the misoperation that may occur while regulating.
The closed cooling tower with stable-pressure device that the utility model provides, installation and convenient, the both sides of described damping orifice plate 4 are respectively equipped with rubber pad 5, and both sides rubber pad 5 can directly be fixedly clamped together by the flange plate 6 on spraying tube 3, does not increase installing space.In order to strengthen heat radiation, the top of described cooling column body 1 also is provided with blower fan 7.
In sum, the closed cooling tower with stable-pressure device that the utility model provides, by being set, the damping orifice plate replace valve to regulate the discharge pressure of water pump, concrete advantage is as follows: 1, reduced cost of material: with a very little Stainless Sheet Steel, replaced a set of valve, but also saved the standard piece such as bolt and nut that connect.2, reduced installation cost: use valve, two groups of flanges, the position of also wanting regulating valve must be installed; And being installed, damping plate is equal to one group of flange of installation.3, saved installing space: mounted valve can be subjected to other component affects, and difficulty is installed; The damping plate mounting design need not be considered the impact of spatial position.Misoperation while 4, preventing the adjusting of water pump water outlet pressure.
Although the utility model discloses as above with preferred embodiment; so it is not in order to limit the utility model; any those skilled in the art; within not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
