Problems solved by technology

[0003] There is a shortcoming in the existing vacuum pump, that is, the pump body must overcome the pressure generated by the internal and external pressure difference during its operation, so that the load of the pump body will increase significantly after starting, and the power loss of the motor will increase significantly (due to part of the power Consumed in overcoming the pressure generated by the internal and external pressure difference), sometimes it even fails to start with load
In addition, the existing vacuum pumps are generally noisy, which is easy to cause noise pollution to the surrounding environment

Embodiment Construction

[0013] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the pressure-free vacuum pump includes a vacuum pump main body, the vacuum pump main body is a slide valve pump, which includes a motor 19, a cylinder 13 and a piston 10, the piston 10 is located in the cylinder 13, and one end of the piston 10 is provided with a connecting rod 12 , the output shaft of the motor 19 is connected with the connecting rod 12 through an eccentric wheel 17 . The motor 19 drives the piston 10 to reciprocate in the cylinder 13 through the eccentric wheel 17, so that the volume in the cylinder changes to realize outward air extraction. The cylinder 13 is provided with a vacuum pump exhaust hole 5 and a vacuum pump exhaust hole 4 . The main body of the vacuum pump is sealed in a housing 1. The housing 1 is provided with an air inlet 24 and an air outlet 23. The housing 1 is also prov...

Abstract

The invention discloses a vacuum pump without pressure difference, which comprises a main body of the vacuum pump, an aspirating hole of the vacuum pump and an exhaust hole of the vacuum pump are arranged on the main body of the vacuum pump, the main body of the vacuum pump is sealed in a housing, and an air inlet and an air outlet are arranged on the housing. The main body of the vacuum pump without the pressure difference is sealed in the housing, when the vacuum pump works, the air inlet on the housing is connected with a device which needs to carry out air aspiration, so that the pressure in the housing is far lower than the pressure outside the housing, the pressure different is acted on the hermetic housing generally, and the main body of the vacuum pump can work under the relatively vacuum state; therefore, a motor of the main body of the vacuum pump always runs under the state without the pressure difference, and the vacuum pump can greatly reduce the power loss, always keep the running state smooth and prolong the service life of the motor. Simultaneously, as the interior of the housing is in the vacuum state almost, the vacuum pump can effectively isolate the mechanical noise produced when the pump body runs, and reduce the noise produced by the vacuum pump.

Description

technical field [0001] The invention relates to a vacuum pump, in particular to a vacuum pump which can work in the state of no pressure difference. Background technique [0002] There are various types of vacuum pumps, which are widely used in plastic machinery, pesticide chemical industry, dye chemical industry, brick and tile machinery, low temperature equipment, papermaking machinery, pharmaceutical chemical industry, food machinery, industrial electric furnace, electronics industry, vacuum equipment, chemical fertilizer, metallurgy, Petroleum, mining, foundation treatment and other fields. The working principle of the vacuum pump is mainly to achieve the purpose of pumping and exhausting through the volume change or extrusion of the container. Existing vacuum pump equipment generally adopts AC and DC motors as the driving force, and the pump body is generally a mechanism such as a piston, a screw, an impeller or a diaphragm, and the pump body is provided with independe...
