Problems solved by technology

The screw vacuum pump used in some equipment that requires high-speed production, because of the fast rotation frequency of the motor, the self-cooling system cannot meet the cooling requirements, and the temperature will be too high during operation, which will cause the machine to fail to operate normally. The production efficiency requirements of the equipment will be changed at any time, and the screw vacuum pump that does not need high-speed production will not generate high temperature
[0003] The existing patent No. CN104329257A proposes a screw rotor cooling device for a screw vacuum pump, which directly cools the vacuum pump through the cooling device installed on the screw, but it needs to completely disassemble the screw when assembling or using the screw vacuum pump. Vacuum pumps can only be installed, the difficulty of installation and maintenance is high, and it will seriously affect the start-up time of production equipment, and the structures and shapes of various existing screw vacuum pumps are quite different, so it is impossible to guarantee the use of any type of screw vacuum pump
[0004] The existing patent number CN101660532B proposes a multi-stage dry vacuum pump water cooling system, which uses multiple pipelines to realize circulating water cooling for the vacuum pump, but it has extremely high requirements on the environment, and the vacuum pump is mostly installed inside the equipment when used on the equipment , the connection of water pipes is difficult, and the water cooling system requires the cooperation of multiple systems such as waterways, and the user needs to manually operate the start and stop, which greatly increases the cost

Abstract

The invention relates to the technical field of screw vacuum pumps, and discloses a screw vacuum pump temperature control device. The screw vacuum pump temperature control device comprises a left fixing ring, a right fixing ring and a cooling ring; a connecting rod is fixedly connected with the bottom end of the front face of the left fixing ring, a cylindrical protrusion is arranged at the tail end of the connecting rod, the outer wall of the connecting rod is sleeved with a sliding block A, the sliding block A is in a rectangular shape, the center of the front face of the sliding block A ishollowed out, and the right side face of the sliding block A is fixedly connected with the cooling ring. Air flow is used for distribution from one end to the other end of the vacuum pump through thecooling ring so as to dissipate heat together with a vacuum pump motor and the vacuum pump, and problems of overheating shutdown of the vacuum pump motor and overheating deformation of the vacuum pumpare avoided; a rotating motor and the vacuum pump operate synchronously, so that the problem of electric energy waste caused by the fact that the rotating motor still operates after the vacuum pump stops operating is avoided; and the rotating speed of the fan can be changed along with the change of the input voltage of the vacuum pump, so that the heat dissipation intensity is automatically adjusted according to the use condition of the vacuum pump.

Description

technical field [0001] The invention relates to the technical field of screw vacuum pumps, in particular to a temperature control device for screw vacuum pumps. Background technique [0002] A device that uses a screw to generate, improve, and maintain vacuum in a closed space is called a screw vacuum pump. The screw vacuum pump used in some equipment that requires high-speed production, because of the fast rotation frequency of the motor, the self-cooling system cannot meet the cooling requirements, and the temperature will be too high during operation, which will cause the machine to fail to operate normally. The production efficiency requirements of equipment will be changed at any time, and screw vacuum pumps that do not require high-speed production will not generate high temperatures. [0003] The existing patent No. CN104329257A proposes a screw rotor cooling device for a screw vacuum pump, which directly cools the vacuum pump through the cooling device installed on ...
