May be the cabinet of aluminium alloy used for manufacturing later, people developed the push-pull cabinet.Push-pull cabinet did not stop the problem, because of push-pull cabinet casement opening and closing of stationary state basic same.

The opening ceremony was chaired by Cui Peng, the deputy director of the Institute of Science and Technology of Hefei University of Technology. Jia Yuzhu, deputy director of the Economic and Social Planning Department of Anhui Province and Zhou Yalin, director of the Standardization Department of the Hefei Quality and Technology Supervision Bureau, introduced the awarding system and international standard innovation of the standardization work situation and editorial standards of Anhui Province and Hefei City respectively. Suggestions and expectations. The Secretary General of the National Pump Standards Committee Secretariat, Han Zhongbao, summarized the work of the last National Standardization Working Group of the National Pump Standards Committee. Chai Liping, Director of the Institute of Chemical Machinery of Hefei University of Technology, reported on the establishment and review of the international pump standard for the Chemical Engine Institute.
At this meeting, the members of the National Pump Standards Committee International Pump Standards Working Group focused on the plans for participating in the 18th session of the International Technical Committee of the Pumping Committee (ISO/TC115) and summarized the results according to ISO/DIS 14414. , Review of the ISO/ASME FDIS 14414:2014 Pump system energy assessment Evaluation of the pump system energy consumption (in English) and the 2015 work plan.
National Pump Standardization Technical Committee International Standards Working Group was established in September 2011. It is the first international standard working group for China's pump industry. Its establishment and work also symbolizes that China's pump industry standardization work has entered international standards. New stage.
One disadvantage of push-pull cabinet is a must have at least one fixed fan, greatly reduce the cabinet area: the other is a fatal weakness could not meet the requirements of air tightness and water tightness.
Of push-pull cabinet casement fixed point is up and down two guide rail, so the wind pressure strength is limited.Modern building more and more high to the requirement of energy conservation and other functions, the sealing of the cabinet, sound insulation and heat insulation, air tightness and water tightness and wind resistance strength and security level, there are strict requirements.To meet the requirements of a variety of integrated and produced within the batter casement cabinets, or the Europe type cabinet.
The cabinet of modern glass curtain wall building model related to the cabinet frame on the wall of the fixed way.Because the glass curtain wall of air tightness, water tightness and wind resistance strength of the demand is higher, on the curtain wall cabinet accessories, according to the need to develop relatively independent.
Modern architecture of the cabinet is not confined to the level of manpower and starting from the requirements of ventilation heat removal, the height of the cabinet is an important factor decided to take a breath row of thermal efficiency, so people invented all kinds of cabinet.
National Pump Standardization Technical Committee International Standard Working Group Meeting Held
From November 24th to November 26th, the 2014 working meeting of the International Standard Working Group of the National Pump Standardization Technical Committee was held at Hefei University of Technology. More than 20 members of the Pump Standards Committee from more than 10 provinces and cities in China, including Shanghai, Jiangsu and Zhejiang, participated in the meeting. meeting.
