Description

Technical Field

[0001] This utility model belongs to the field of vacuum pump cooling technology, specifically relating to a cooling circulation system for mechanical pumps. Background Technology

[0002] Mechanical pumps, widely used in industrial applications, generate significant heat during operation due to friction between the motor windings, bearings, pump body, and the pumped medium. If this heat cannot be dissipated effectively and promptly, it can lead to problems such as decreased motor insulation, accelerated bearing wear, and aging of pump body seals, potentially causing equipment failure and shutdown in severe cases.

[0003] In existing technologies, the commonly used cooling methods for mechanical pumps mainly include air cooling, water cooling, and oil cooling. Air cooling has a simple structure but limited cooling efficiency, making it difficult to meet the heat dissipation requirements under high power or high temperature conditions; traditional water cooling systems require an external cooling water source, which places high demands on water resources and significantly restricts their application; oil cooling systems suffer from system complexity and high maintenance costs. External cooling systems are subject to limitations imposed by the operation of the external system during the cooling water delivery process, greatly reducing the cooling effect. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a cooling circulation system for mechanical pumps, which generates chilled water through negative pressure and airflow for cooling the mechanical pumps.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The cooling circulation system for a mechanical pump described in this utility model includes a vaporizer, which includes an externally mounted jacket. An airflow delivery pipe is provided at the bottom of the vaporizer, and a buffer tank is connected to the top of the vaporizer. A vacuum mechanical pump is connected to the top of the buffer tank, and a water storage tank is connected to the vacuum mechanical pump. The bottom of the water storage tank is connected to the bottom of the vaporizer. A heat exchange coil is provided outside the vacuum mechanical pump, and a circulating water pump is connected to the bottom of the jacket. The circulating water pump is connected to the heat exchange coil, and the heat exchange coil is connected to the upper part of the jacket.

[0007] in:

[0008] The vaporizer has an internal vaporization chamber, and a jacket is located on the outside of the vaporization chamber.

[0009] The airflow delivery pipe is located at the bottom of the vaporization chamber, and a water discharge pipe is provided at the bottom of the vaporization chamber.

[0010] A regulating valve is installed between the bottom of the water storage tank and the bottom of the vaporizer.

[0011] The heat exchange coil is provided with a cooling water inlet at the bottom and a cooling water outlet at the top. The circulating water pump is connected to the cooling water inlet and the cooling water outlet is connected to the upper part of the jacket.

[0012] An airflow controller is installed between the buffer tank and the vacuum mechanical pump.

[0013] The airflow controller is designed in a U-shape. The top of the U-shape is connected to the inlet of the vacuum mechanical pump, and valves are provided on the left and right sides of the bottom of the U-shape. The buffer tank is connected to one side of the bottom of the U-shape.

[0014] The buffer tank is equipped with a drain valve at the bottom.

[0017] The scale inhibitor is one of sodium benzotriazole, organophosphate, polyphosphoric acid, or sodium ethylenediaminetetraacetate; the wetting agent is one of ethylene glycol, glycerol, propylene glycol, phosphate salt, sulfonate, polyoxyethylene alkylphenol, polyoxyethylene ether, or fatty alcohol polyoxyethylene ether, and the amount of scale inhibitor added is 0-8 mg / L.

[0018] The beneficial effects of this utility model are:

[0019] This invention achieves independent cooling through the cooperation of a vacuum mechanical pump and a vaporizer, without relying on external energy. The integrated heat exchange coil on the vacuum mechanical pump enables autonomous cooling, eliminating the need for an external cooling water source and avoiding additional energy consumption. Furthermore, the combined cooling process and structure of this invention result in high cooling efficiency, uniform cooling, a compact structure, and low energy consumption. The heat exchange coil, spirally wound around the outside of the vacuum mechanical pump, effectively transfers heat, achieving uniform cooling of the pump cavity area. The heat exchange coil and jacket continuously exchange heat, ensuring stable heat transfer in the vacuum mechanical pump. This increases the heat exchange area, shortens the heat exchange path, and achieves comprehensive, uniform, and efficient cooling of the vacuum mechanical pump body, effectively preventing localized overheating.

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] Example 1

[0025] like Figure 1-2 As shown, the cooling circulation system for a mechanical pump described in this utility model includes a vaporizer 1, which includes an externally arranged jacket 102. An airflow delivery pipe 7 is provided at the bottom of the vaporizer 1. A buffer tank 2 is connected to the top of the vaporizer 1. A vacuum mechanical pump 3 is connected to the top of the buffer tank 2. A water storage tank 4 is connected to the top of the vacuum mechanical pump 3. The bottom of the water storage tank 4 is connected to the bottom of the vaporizer 1. A heat exchange coil 11 is provided on the outside of the vacuum mechanical pump 3. A circulating water pump 5 is connected to the bottom of the jacket 102. The circulating water pump 5 is connected to the heat exchange coil 11. The heat exchange coil 11 is connected to the upper part of the jacket 102.

[0026] The vaporizer 1 has a vaporization chamber 101 inside, and a jacket 102 is located outside the vaporization chamber 101.

[0027] An airflow delivery pipe 7 is located at the bottom of the vaporization chamber 101, and a water discharge pipe 6 is located at the bottom of the vaporization chamber 101.

[0028] A regulating valve 10 is installed between the bottom of the water storage tank 4 and the bottom of the vaporizer 1.

[0029] The heat exchange coil 11 has a cooling water inlet at the bottom and a cooling water outlet at the top. The circulating water pump 5 is connected to the cooling water inlet and the cooling water outlet is connected to the top of the jacket 102.

[0030] An airflow controller 9 is installed between the buffer tank 2 and the vacuum mechanical pump 3.

[0031] The airflow controller 9 is designed in a U-shape. The top of the U-shape is connected to the inlet of the vacuum mechanical pump 3, and valves are installed on the left and right sides of the bottom of the U-shape. The buffer tank 2 is connected to one side of the bottom of the U-shape.

[0032] A drain valve 8 is installed at the bottom of the buffer tank 2.

[0033] A balance water pipe 401 is installed on the top of the water storage tank 4, and a liquid level monitor is installed inside the water storage tank 4.

[0034] The interlayer 102 contains water, which is tap water, purified water or deionized water, and one or more of scale inhibitors, wetting agents or antifreeze are added to the water.

[0035] The scale inhibitor is one of sodium benzotriazole, organophosphate, polyphosphoric acid, or sodium ethylenediaminetetraacetate; the wetting agent is one of ethylene glycol, glycerol, propylene glycol, phosphate salt, sulfonate, polyoxyethylene alkylphenol, polyoxyethylene ether, or fatty alcohol polyoxyethylene ether, and the amount of scale inhibitor added is 0-8 mg / L.

[0036] Working principle and process:

[0037] When the vacuum mechanical pump 3 is working, all valves at the bottom of the airflow controller 9 are open, one side is connected to the working system, and the other side is connected to the buffer tank 2. The vacuum mechanical pump 3 can also perform vacuuming operation on the vaporization chamber 101 inside the vaporizer 1, and together with the airflow delivery pipe 7, it delivers high-speed airflow into the vaporization chamber 101. After the high-speed airflow enters the negative pressure environment, it bubbles in the vaporization chamber 101, which can accelerate the vaporization process of water and continuously absorb heat. The jacket 102 is set outside the vaporization chamber 101, which can make the water temperature inside the jacket 102 drop rapidly, forming chilled water. The circulating water pump 5 is activated to draw chilled water into the heat exchange coil 11 to cool the vacuum mechanical pump 3. The cooled water is then discharged back into the vaporization chamber 101. The airflow drawn by the vacuum mechanical pump 3 into the vaporization chamber 101 is buffered by the buffer tank 2 and then enters the water storage tank 4 for liquefaction. The liquid level monitor in the water storage tank 4 can monitor the liquid level in the water storage tank 4 in real time. The water in the water storage tank 4 can return to the bottom of the vaporization chamber 101 to replenish the water, realizing water circulation. The liquid level in the water storage tank 4 can also be balanced through the balancing water pipe 401. This utility model achieves rapid cooling of water under the dual action of negative pressure and airflow.
