Abstract

The invention relates to the technical field of a pump and particularly relates to a novel double-rotary-blade type vacuum pump, which is characterized by comprising an air inlet nozzle, a rotary filtering net, an oil baffling plate sealing ring, an air inlet O-shaped sealing ring, a rotary blade spring, rotary blades, a rotor, a pump body, an oil tank, vacuum pump oil, an air discharging valve sheet, an air inlet pipe and an oil baffling plate. According to the novel double-rotary-blade type vacuum pump, the air inlet nozzle is provided with the rotary filtering net and the oil baffling plate is provided with the oil baffling plate sealing ring; and the rotary filtering net is made of flexible net rubber so that the corroding air is purified and the service life of the vacuum pump is prolonged.

Description

[technical field] [0001] The invention relates to the technical field of pumps, in particular to a novel double-rotary vane vacuum pump. [Background technique] [0002] The rotary vane vacuum pump operates under high vacuum conditions, and it is particularly prone to oil return after shutdown, which affects the function of the pump. [Content of the invention] [0003] In order to solve the above-mentioned deficiencies, the present invention provides a novel double-rotary vane vacuum pump. The novel double-rotary vane vacuum pump is characterized in that it includes: an air inlet nozzle 1, a rotating filter screen 2, an oil baffle seal Ring 3, intake O-ring 4, vane spring 5, vane 6, rotor 7, pump body 8, oil tank 9, vacuum pump oil 10, exhaust valve plate 11, intake pipe 12, oil baffle 13, all Describe a kind of novel double-rotary vane vacuum pump, be provided with rotary filter screen 2 at air intake nozzle 1, be provided with oil baffle seal ring 3 on described oil baff...
