Problems solved by technology

Fan replacement: It has a great impact on production, long-term dismantling, commissioning and installation, etc. affect the normal use of equipment, and batch replacement funds also have certain cost pressures; damper control, as a mechanical component for wind adjustment, is unavoidable in the air duct Due to long-term use, the mechanical components are jammed, causing the adjustment function to fail
The disadvantage of using frequency conversion management and control technology is that the value of a single unit is as high as tens of thousands of yuan. As a large space, the demand is also large. Considering the cost pressure, it is generally not adopted.
How to break through the limitations, effectively realize the control, and ensure the realization of the parameters of the equipment is particularly difficult

Embodiment Construction

[0015] Referring to the accompanying drawings, the chamber space 1 in the embodiment can be a spray booth, or a working room that needs to maintain a certain air circulation index. In order to maintain the air flow index in the chamber space 1, the blower 2 of the air intake system passes through The air supply pipe delivers fresh air to the chamber space 1, and then the air in the chamber space 1 is discharged outward by the exhaust pipe 4 and the exhaust fan 3 connected with the chamber space 1, so as to maintain the air in the chamber space 1. air quality and air pressure, in the exhaust system of the present application, a bypass air supply port is set on the side of the exhaust pipe, the air supply pipe 5 is connected to the exhaust pipe 4 through the flange 6, the air supply pipe 5, the exhaust air The pipe 4 is integrally connected with the exhaust fan 3, and the cross section of the bypass air supply pipe is set to be 60-80% of the cross section of the exhaust pipe. Th...

Abstract

The invention discloses a box chamber space inner air pressure adjusting method. An air inlet system for supplying air into a box chamber space and an air outlet system for exhausting air outwards from the box chamber space are included. The air outlet system comprises an exhaust pipe and an exhaust fan which communicate with the box chamber space, in addition, an air supplementing pipe of a bypass communicates with the exhaust pipe, and a port of the air supplementing pipe is provided with an air volume adjusting structure and communicates with the atmosphere. The air inlet volume of the air supplementing pipe is adjusted through the air volume adjusting structure, and accordingly the air pressure of the box chamber space is adjusted.

Description

technical field [0001] The application relates to the ventilation technology of the chamber space, and is especially suitable for adjusting the wind pressure in the chamber space. Background technique [0002] In industrial production, ventilation is not only used in the basic configuration of workshops, but also in some special closed workplaces, the ventilation system is also responsible for heat cycle transfer, chamber air pressure control, humidification and drying, airflow disturbance intervention, control of the spread of air pollutants and Hazardous and ensure air quality and many other functions. According to the exhaust method, ventilation technology is divided into two types: natural ventilation and mechanical ventilation. In some places that are relatively closed and have requirements for ventilation indicators, forced mechanical exhaust is required and controlled to ensure the realization of many technical data of the equipment. [0003] In ventilation design an...
