[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0014] like Figure 1 As shown, a liquid storage tank cooling structure includes a support 1 and a mechanical oil seal 11. A liquid storage tank 2 is fixedly installed at the front end of the support 1. A manual pressure pump 5 is installed on the top of the liquid storage tank 2 to pressurize the tank. The outlet of the manual pressure pump 5 is connected to the inside of the liquid storage tank 2. A liquid injection hole 3 is provided on one side of the top of the liquid storage tank 2 for replenishing the tank. A liquid level gauge 4 is welded to the outer surface of the liquid storage tank 2 to observe the liquid level and facilitate timely replenishment of the tank. An outlet pipe 8 is fixedly installed at the bottom of the liquid storage tank 2, and an inlet pipe 9 is fixedly installed on the side of the liquid storage tank 2. The outlet pipe 8 is sealed to the inlet of the mechanical oil seal 11, and the inlet pipe 9 is sealed to the outlet of the mechanical oil seal 11.
[0015] The liquid outlet pipe 8 is folded into a coil structure, and a heat sink 10 is fixedly installed on the outside of the liquid outlet pipe 8.
[0016] A pressure gauge 6 and a thermometer 7 are fixedly installed on the outer surface of the liquid storage tank 2. The thermometer 7 is used to observe the temperature of the liquid inside the tank, and the pressure gauge 6 is used to test the pressure inside the tank.
[0017] The working principle of this utility model is as follows: the manual pressure replenishing pump 5 replenishes the pressure of the liquid in the tank, the pressure range is observed by the pressure gauge 6, and the temperature gauge 7 shows the temperature of the liquid in the storage tank 2. The liquid enters the outlet pipe 8 from the storage tank 2, and the heat sink 10 cools the liquid in the outlet pipe 8, so that the liquid output from the storage tank 2 is always kept at a low temperature. Then it flows in from one end of the mechanical oil seal 11, carrying away the mechanical seal temperature and its medium impurities. Then it flows out from the outlet and enters the inlet pipe 9. Finally, it flows back to the storage tank 2 through the inlet pipe 9. This process is repeated to ensure that the mechanical oil seal 11 is always at a normal temperature, thereby increasing the service life of the mechanical oil seal 11.
[0018] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
