Problems solved by technology

This dry pump has an obvious technical defect: when it is idling (Idle), that is, when the pressure of the intake pipe 400 is 0, there is a certain pressure difference between the pressure in the last-stage pump chamber 100 and the atmospheric pressure, and this pressure difference will Causes dry pumps to consume large amounts of electricity

Embodiment Construction

[0028] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0029] see figure 2 Firstly, the present invention provides a system for reducing power consumption of a dry pump, including a dry pump 2 and a power saving module 4 arranged outside the dry pump 2 and connected to the dry pump 2 .

[0030] The dry pump 2 includes multi-stage pump chambers 21 that communicate with each other. A rotor 23 is installed in each pump chamber 21. The first-stage pump chamber 21 is directly connected to the intake pipeline 25, and the last-stage pump chamber 21 is connected to the exhaust pipe. Pipeline 27 communicates directly. When the dry pump 2 is working, each rotor 23 rotates, so that the volume of the corresponding pump chamber 21 changes periodically, and the air pumping is realized by using the opening and...

Abstract

The invention provides a system and a method for reducing power consumption of a dry pump. The system for reducing the power consumption of the dry pump is additionally provided with an electricity saving module (4) connected with the dry pump (2), wherein the electricity saving module (4) comprises a reducing valve (41); an admission end (A) of the reducing valve (41) is communicated with an outlet end (C) of an exhaust line (27) of the dry pump (2); and a vent end (B) of the reducing valve (41) is communicated with atmosphere. When the dry pump (2) is in an idling state, the reducing valve (41) can reduce pressure at the outlet end (C) of the exhaust line (27) to result in vacuum; negative pressure is kept in the exhaust line (27); compared with the prior art, the pressure of a final stage pump cavity (21) of the dry pump (2) is reduced to the negative pressure instead of atmospheric pressure; the pressure that the final stage pump cavity (21) is required to reach is decreased; rotating speeds of corresponding rotors (23) in pump cavities (21) at all stages are reduced; and the load power of the dry pump (2) is reduced, so that the power consumption of the dry pump can be reduced effectively.

Description

technical field [0001] The invention relates to the technical field of vacuum pumps, in particular to a system and method for reducing power consumption of dry pumps. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Usually, the liquid crystal display panel consists of a color filter (CF, Color Filter) substrate, a thin film transistor (TFT, Thin Film Transistor) substrate, a liquid crystal (LC, Liquid Crystal) and a sealant frame (Sealant) sandwiched between the color filter substrate and the thin film transistor substrate. )composition. In the production process of the TFT substrate, it is necessary to complete each metal film laye...
