Description

Technical Field

[0001] The utility model relates to the technical field of cooling pumps, in particular to a device for preventing eddy currents from being generated at a suction port of a cooling pump. Background Art

[0002] At present, cooling towers are widely used as heat dissipation devices for chillers. The working principle of cooling towers is as follows: the cooling water pump pressurizes the water in the cooling tower sump and flows it into the chiller evaporator to take out the heat. The hot water is transported to the top of the cooling tower and evenly sprinkled on the filler by a water distributor to dissipate heat through the fan. The cooling water is then retained from the gaps in the filler and collected in the cooling tower sump. In order to reduce the occupation of land, cooling towers are generally built on the roof. In order to reduce the weight of the cooling tower, the water storage capacity of most water collectors is not large. The cooling water flow of large chillers is very large. When the water pump draws water from the sump, the flow rate is too fast, which will cause vortex phenomenon, resulting in a large amount of air being sucked into the cooling water pipe.

[0003] If a large amount of air enters the cooling water pump, it will destroy the operating conditions of the water pump, causing serious insufficient water pressure and flow at the water pump outlet, resulting in poor heat dissipation of the chiller and abnormal shutdown. Once air is mixed into the cooling water, it will take a lot of time to exhaust the air. In severe cases, the chiller evaporator will be damaged, causing damage to the entire chiller. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a device for preventing eddy currents from being generated at the suction port of a cooling pump, thereby solving the problem that the operating conditions of the cooling water pump will be destroyed if a large amount of air enters the cooling water pump.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a device to prevent vortexes from being generated at the suction inlet of a cooling pump, comprising a stainless steel cover shell, the surface of the stainless steel cover shell is provided with evenly distributed water flow dispersion holes, a sealing cover plate is fixedly installed on the stainless steel cover shell, a water pipe connector is fixedly connected to the surface of the sealing cover plate, a sealing sleeve is detachably installed on the water pipe connector, a first clamp is detachably installed on the outer side of the sealing sleeve, and a second clamp corresponding to the first clamp is arranged on the side of the first clamp.

[0006] Preferably, an opening is provided at one end of the stainless steel cover shell, and a sealing portion is provided at the other end of the stainless steel cover shell.

[0007] Preferably, the sealing cover plate is made of stainless steel, and the sealing cover plate is connected to the stainless steel cover shell by welding.

[0008] Preferably, a groove is provided on the surface of the sealing cover plate, and the water pipe connector is fixedly installed at the bottom of the groove.

[0009] Preferably, a limiting sleeve is fixedly installed on the outer side of the water pipe connector, a gap is provided between the limiting sleeve and the water pipe connector, and the sealing sleeve gasket is detachably installed inside the gap.

[0010] Preferably, first ear plates are provided on both sides of the first clamp, and second ear plates are provided on both sides of the second clamp, and the first ear plates are mounted on the second ear plates by bolts.

[0011] Beneficial Effects

[0012] The utility model provides a device for preventing eddy current from being generated at the suction port of a cooling pump. Compared with the prior art, it has the following beneficial effects:

[0013] The device for preventing vortex from being generated at the suction port of the cooling pump is provided with a stainless steel cover and water flow dispersion holes, so that the stainless steel cover covers the water inlet of the water pipe, so that no vortex will be generated in the middle of the suction port of the cooling pump. However, since the stainless steel cover is in a shallow position underwater, small vortex may be generated again on the side due to excessive flow rate. Therefore, the water flow dispersion holes on both sides below the stainless steel cover are made smaller to divide and disperse the energy of the lateral water flow, so that vortex cannot be generated, thereby avoiding air intake. This can prevent a large amount of air from entering the cooling water pump and destroying the operating conditions of the water pump, avoid causing serious shortage of water outlet pressure and flow of the water pump, and further avoid damage to the chiller evaporator and damage to the entire chiller.
