Abstract

The invention provides a vacuum negative pressure unit and a control method thereof. The vacuum negative pressure unit comprises a main air inlet pipeline, a plurality of vacuum pumps and a control device, the main air inlet pipeline is connected with a main pipeline, the main pipeline is connected with the plurality of vacuum pumps, a first pressure detection device and a pressure switch are arranged on the main pipeline, the control device is used for controlling the vacuum pumps according to the gas pressure in the main pipeline, and the pressure switch is configured to control starting andstopping of the vacuum pumps when the control device fails. According to the vacuum negative pressure unit and the control method, a modular platform connection manner is adopted, rapid constructionof the unit is realized, meanwhile, different requirements of a user on the vacuum degree are met, the operation safety of the whole vacuum negative pressure unit can also be ensured through differentpressure control manners when the control device is in a normal or abnormal working state, the vacuum gas meeting the predetermined requirement is generated at the same time, and the control of the vacuum negative pressure unit can effectively avoid the accident caused by pressure loss.

Description

technical field [0001] The present disclosure relates to the field of mechanical equipment and mechanical control, in particular to a vacuum negative pressure unit and a control method thereof. Background technique [0002] A vacuum pump is a device that uses a vacuum compressor to generate a relatively vacuum environment and maintain a stable vacuum. It is widely used in petrochemical, pharmaceutical, paper, plastic, food and other industries. Although vacuum pumps are widely used in various industries, there are the following problems in the application of vacuum pumps: the vacuum pump works alone, without pressure storage equipment, must be equipped with a pressure storage tank, and the work efficiency is not high; In addition, it is used for power distribution and electric control; there is no voltage loss protection device, which may easily cause misoperation of application equipment and damage to equipment. As manufacturers have higher and higher requirements for vacu...
