Transmission mode and mechanical installation of Edward vacuum pump

The arrangement of the pump body of the Edward vacuum pump determines the overall structure of the pump. The intake and exhaust ports of the vertical structure are set horizontally, which is convenient for assembly and connection of pipelines. However, the center of gravity of the pump is high, and the stability is poor at high speed, so this type is mostly used for small pumps. The following editor introduces the transmission mode of Edward vacuum pump and the content of mechanical installation, welcome to read!

Transmission mode of Edward vacuum pump:

The two rotors of the Edward vacuum pump are operated relatively synchronously through a pair of high-precision gears. The driving shaft is connected with the motor through a coupling. There are two main types of transmission structure layout: one is that the motor and the gear are placed on the same side of the rotor as shown in the figure. The driven rotor is directly driven by the motor end gear, so that the torsional deformation of the driving rotor shaft is small, the gap between the two rotors will not be changed due to the large torsional deformation of the driving shaft, so the gap between the rotors is running. uniform in the process. The major disadvantages of this transmission method are: a. There are three bearings on the driving shaft, which increases the difficulty of processing and assembling the pump, and the disassembly and adjustment of the gear is inconvenient; b. The overall structure is not symmetrical, and the center of gravity of the pump is biased towards the motor and gear. side of the box. 19683134197_948543960 (1).jpg

Mechanical installation of Edward vacuum pump:

(1) The vacuum pump should be installed in a place with a solid and solid ground, and there should be sufficient space around it to facilitate inspection, maintenance and maintenance.

(2) The foundation should be kept level under the base of the vacuum pump. It is recommended to cushion the four corners of the base with shock-absorbing rubber or cast it with bolts to ensure that the vacuum pump runs smoothly and has little vibration.

(3) The connection pipeline between the vacuum pump and the system should be sealed and reliable. For small vacuum pumps, metal pipelines can be used to connect the gasket and oil-resistant rubber. For small vacuum pumps, vacuum hoses can be used to connect. And less elbows. (When welding the pipeline, the welding slag in the pipeline should be removed, and the welding slag is strictly prohibited from entering the vacuum pump chamber.)

⑷In the connecting pipeline, the user can install a valve and a vacuum gauge above the air inlet of the vacuum pump to check the limit pressure of the vacuum pump at any time.

⑸Connect the power supply according to the regulations of the motor plate, and install the fuse and thermal relay of appropriate specifications.

⑹ When the vacuum pump is energized for trial operation, the motor belt must be removed, and the vacuum pump must be turned in the specified direction before it can be put into use to prevent the vacuum pump from reversing oil injection. (Turn to the direction indicated by the protective cover)

⑺For the vacuum pump with cooling water, connect the cooling water according to regulations.

⑻ If a solenoid valve is installed at the vacuum pump port, the valve and the vacuum pump should act at the same time.

⑼ When the exhaust gas from the vacuum pump affects the working environment, a pipeline can be installed at the exhaust port to lead away or an oil mist filter can be installed.
