Technical Field

[0001] The utility model relates to the technical field of vacuum pumps, in particular to a dry claw vacuum pump. Background Art

[0002] A claw-type dry vacuum pump is a variable displacement dry vacuum pump with a claw-shaped rotor. Claw-type dry vacuum pumps typically utilize a multi-stage claw-type dry vacuum pump structure with multiple rotors connected in series, or with a Roots rotor and a multi-stage rotor connected in series.

[0003] The claw vacuum pump needs to be supported and installed with a bracket when in use, but it needs to be replaced and disassembled for reinstallation when the actual use position is different, so it needs to be improved, and the temperature needs to be adjusted when used for a long time to avoid temperature increase affecting the service life.

[0011] Preferably, a first limiting rod is welded to the bottom end surface of the panel, a second limiting rod is sleeved on the first limiting rod, and the bottom end surface of the second limiting rod is welded to the base. By sleeved on the first limiting rod, the panel can be mounted on the base via the first and second limiting rods, thereby enabling the panel to be installed and limited.

[0012] Preferably, the bottom end surface of the base is equipped with universal wheels, and there are four universal wheels in total, and the four universal wheels are distributed in a rectangular array relative to the base. The universal wheels are installed on the bottom end surface of the base, so that when using the vacuum pump body, the user can push the base to reach the designated position to be used.

[0013] Preferably, an exhaust pipe is embedded and fixed in the fixed pipe, and the exhaust pipe is in gas communication with the fixed pipe, so that the gas entering the fixed pipe can be discharged through the exhaust pipe.

[0014] Preferably, the mounting plate is threaded with bolts, and the bolts are threadedly mounted in the panel. The mounting plate can be mounted on the panel by the bolts, and the mounting plate can be disassembled by reversing the bolts, thereby installing and disassembling the vacuum pump body.

[0018] 1. The utility model sets a vacuum pump body. When personnel use the vacuum pump body, they can install the vacuum pump body on the panel for installation and use. When in use, in order to avoid temperature increase after long-term use, personnel extract the gas in the box through the fan. The box takes in air through the air inlet pipe 2. When taking in air, the gas can be filtered through the filter element and then extracted for use. The gas in the box can be extracted by turning on the fan. When extracting, the gas can be injected into the fixed pipe, so that the gas can be discharged through the exhaust pipe. The driving position of the vacuum pump body can be dissipated to avoid temperature increase affecting the use operation.

[0019] 2. The utility model sets a panel. When personnel use the vacuum pump body, universal wheels are installed through the bottom end surface of the base, so that personnel can push the base to reach the designated position when using the vacuum pump body. After reaching the position, the panel can be installed on the base through limit rods 1 and 2. After installation, personnel can turn on the drive motor to drive the screw to rotate. According to the rotation direction of the screw, the panel can be driven up and down to adjust the use position and height, avoiding the impact of the adjustment after the installation of a single bracket, thereby meeting the adjustment according to actual use needs.
