[0019] Please refer to Figure 1 , the embodiments of the present utility model include:

[0020] Embodiment 1

[0021] The present utility model discloses a diaphragm compressor cooling system, including a diaphragm compressor cooler 10, a chiller 20, a heat preservation water tank 30 and a water pump 40.

[0022] Among them, the diaphragm compressor cooler 10 is built into the diaphragm compressor and is used to hold cooling water to cool the cylinders and gas of the diaphragm compressor.

[0023] The heat preservation water tank 30 is provided with a water inlet port 31, a first return water port 32, a second return water port 33, a first water outlet port 34 and a second water outlet port 35.

[0024] Specifically, the water inlet port 31 of the heat preservation water tank 30 is connected to a fresh water source 50 through a pipeline. The fresh water source can be tap water and is used to supplement water to the entire cooling system. A water softening device 60 is also installed on the pipeline between the water inlet port 31 and the fresh water source 50. The water softening device is a commercially available water softening equipment, which is used to remove calcium ions, magnesium ions and other impurities in tap water, so as to reduce impurities, scale sludge and microbial communities attached to the inner side of the pipe wall, increase the heat exchange efficiency of the cooling system, and effectively control the exhaust temperature of each stage of the compressor.

[0025] A float switch valve is installed in the heat preservation water tank 10 to control the opening and closing of the water inlet port 31. Specifically, when the water level in the heat preservation water tank 10 rises to the highest liquid level, the float switch valve closes the water inlet port 31. When the water level in the heat preservation water tank 10 drops to the lowest liquid level, the water inlet port 31 opens, and water is supplemented into the heat preservation water tank 30 through the fresh water source.

[0026] The first return water port 32 and the first water outlet port 34 of the heat preservation water tank 10 are respectively connected to the water outlet and water inlet of the chiller 20. The water in the heat preservation water tank 30 enters the chiller 20 for cooling and then returns to the heat preservation water tank, and so on. Through the design of the chiller 20, the water of the entire cooling system is cooled down.

[0027] The second return water port 33 and the second water outlet port 35 of the heat preservation water tank 30 are respectively connected to the water outlet and water inlet of the diaphragm compressor cooler 10. On the one hand, the cooling water in the heat preservation water tank 30 can continuously enter the diaphragm compressor cooler 10 as a cooling medium. On the other hand, the cooling water after heat exchange in the diaphragm compressor cooler 10 continuously flows back into the heat preservation water tank 30 and then enters the chiller 20 for cooling, so as to realize the effective operation of the entire cooling system.

[0028] The water pump 40 is installed on the pipeline between the second water outlet port 35 of the heat preservation water tank 30 and the water inlet of the diaphragm compressor cooler 10, and is used to convey the water in the heat preservation water tank 30 into the diaphragm compressor cooler 10. In addition, a bypass pipeline is provided between the second water outlet port 35 of the heat preservation water tank 30 and the water inlet of the diaphragm compressor cooler 10, and a standby water pump 70 is installed on the bypass pipeline to prevent the failure of the water pump 40 from affecting the effective operation of the cooling system.

[0029] A liquid level gauge (not shown) and a temperature sensor (not shown) are also provided in the heat preservation water tank 30. The cooling system is also provided with a program controller.

[0030] Specifically, both the liquid level gauge and the temperature sensor are connected to the program controller in a signal connection manner.

[0031] Among them, the liquid level gauge is connected to the switching valve of the chiller 20 in a linkage control manner through the program controller. When the liquid level value measured by the liquid level gauge reaches the set liquid level value, the water inlet port 31 of the heat preservation water tank 30 is closed and the water inlet is stopped. The program controller controls the chiller 20 to start, and the water in the heat preservation water tank 30 enters the chiller 20 for circulating cooling, and the cooling system starts.

[0032] The temperature sensor is connected to the switching valves of the water pump 40 and the standby water pump 70 in a linkage control manner through the program controller.

[0033] When the program controller receives the water temperature in the heat preservation water tank 30 measured by the temperature sensor and determines that it reaches the set temperature, it controls the water pump 40 to start, and conveys the water in the heat preservation water tank 40 into the diaphragm compressor cooler 10 for cooling down the diaphragm compressor. When the water pump 40 fails, is under maintenance or other situations that affect normal use, the program controller controls the standby water pump 70 to start to convey cooling water.

[0034] The working principle or working process of a diaphragm compressor cooling system of the present utility model is as follows:

[0035] Fresh water source (tap water) first enters the heat preservation water tank after being treated by the water softening device. When the water in the heat preservation water tank reaches the set liquid level, the float switch valve closes the water inlet port, starts the chiller, the water in the heat preservation water tank enters the chiller for cooling, and then flows back to the heat preservation water tank. When the water temperature measured by the temperature sensor in the heat preservation water tank reaches the set value, the water pump is started, and the cooling water in the heat preservation water tank is conveyed to the diaphragm compressor cooler, and at the same time, the water after heat exchange in the diaphragm compressor cooler flows back to the heat preservation water tank.

[0036] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included within the patent protection scope of the present utility model.
