Detailed Implementation
[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0013] Example 1 like Figures 1-3 As shown, the automatic pump body temperature control device in this embodiment is installed on the vacuum pump unit. The vacuum pump unit includes an upper pump body 1 and a lower pump body 2 connected in series. The automatic control device mainly includes a main inlet cooling pipe 10, a main outlet cooling pipe 20, and a first tee 30 connected to the main inlet cooling pipe 10. The first tee 30 divides the main cooling pipe into a normal cooling pipe group and a regulating cooling pipe group.
[0014] The main inlet cooling pipe 10 is used to connect to the cooling medium, and the main outlet cooling pipe 20 is used to discharge the cooling medium. The ends of the normal cooling pipe group and the regulating cooling pipe group are connected to the main outlet cooling pipe 20 through the second tee. A flow meter 11 is installed on the main inlet cooling pipe 10. The flow meter 11 is located before the first tee 30 and detects the total flow rate of the cooling liquid.
[0015] Specifically, the normal cooling pipe is connected to the lower pump motor 201 and the upper pump body 1. The normal cooling pipe includes multiple connected first pipes 51, second pipes 52, third pipes 53 and fourth pipes 54. The first pipe 51 is connected to the lower pump motor 201, and the second pipes 52, third pipes 53 and fourth pipes 54 are connected to the upper pump body 1. More specifically, the second pipe 52 is connected to the upper pump motor 101, the third pipe 53 is connected to the upper pump oil tank 102, and the fourth pipe 54 is connected to the upper pump gearbox 103. After entering the upper pump motor 101, the coolant flows into the upper pump oil tank 102, then into the upper pump gearbox 103, and finally into the second tee.
[0016] The cooling pipe assembly is connected to the lower pump body 2. The temperature control valve 40 is used to detect the temperature of the lower pump body 2 and to control the opening and closing of the cooling pipe assembly. The cooling pipe assembly includes a fifth pipe 61, a sixth pipe 62, and a seventh pipe 63 that are connected. The fifth pipe 61, the sixth pipe 62, and the seventh pipe 63 are connected to the lower pump body 2. The temperature control valve 40 is installed on the fifth pipe 61. When the initial fifth pipe 61 is cut off, the subsequent sixth pipe 62 and seventh pipe 63 are also disconnected.
[0017] More specifically, the fifth pipe 61 is connected to the lower pump gear oil tank 202, the sixth pipe 62 is connected to the lower pump gearbox 203, and the seventh pipe 63 is connected to the lower pump housing 204.
[0018] Therefore, during use, the upper pump motor 101, upper pump oil tank 102, upper pump gearbox 103 in the upper pump body 1 and the lower pump motor 201 in the lower pump body 2 are cooled normally through the normal cooling pipes. The lower pump oil tank 202, lower pump gearbox 203 and lower pump housing 204 in the lower pump body 2 are cooled only after the temperature control valve 40 detects that a certain temperature value has been reached through the adjustment of the cooling pipe assembly.
[0019] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
