December 12, Shanghai Heng Extension Hydraulic Control Technology Co., Ltd. 2017 winter new conference to 'do 100 years of reliable work of the servo valve' as the theme of the Shanghai Tianping Hotel brilliant debut from all over the country customers and major universities research cooperation Partners come together, although the Shanghai cold wind in December, but did not affect the enthusiasm and confidence of customers ordering.
Mr. Huang Zeng, General Manager of Hengtuo Hydraulics, introduced the performance and long-life advantage of our new WS-B fuel jet electro-hydraulic servo valve to the guests on the theme of "Servo Valve for 100 Years of Reliable Work" , Explain profound theories in simple language to analyze the company's development ideas and key measures in the next stage.
General Manager Huang said: Hengtuo hydraulic products with excellent reliability, foreign servo valve is not irreplaceable! Hengtuo hydraulic people-oriented, will be a strong and stable construction team to support our servo valve business will be excellent products Quality and service quality to win the recognition of all parties. Hengtuo hydraulic servo valve in the field of aviation applications, so that the world can see the Chinese made of excellent quality.
Do 100 years of reliable work of the servo valve
As the heart of the aircraft, the aviation fuel valve has always been the key.Air fuel valve development difficult, long cycle, the replacement of the fuel valve is the basis for aircraft improvement.Military powerThe United States, Russia, Britain and France aviation fuel Valves are independent research and development, such as the United States GE, Pratt & Whitney; Britain's Rolls-Royce (Rolls-Royce) and Russia's Saturn, Salute, etc. Fuel servo valve as the aircraft's core device, which is responsible for the computer control signal into a powerful The hydraulic action, although seemingly modest, but in fact huge energy.
'WS-B-type fuel jet electro-hydraulic servo valve' is the Shanghai Heng Extension Hydraulic Control Technology Co., Ltd. Relying on the CSIC No. 70 Institute of the solid technical strength and industrial science and technology base, successfully applied to multi-type domestic aircraft star Products, and Shanghai Airlines made a series of products.
Since the seventies of last century, from the development of the first marine jet valve servo valve began to accumulate related technologies, began in 2009, widely used in the field of aviation.
Shanghai Heng Extension Hydraulic Control Technology Co., Ltd. R & D personnel step by step, from the theoretical mathematical model of the building, to the key technologies of the experimental verification, and then to the system verification and semi-physical test validation, and installed after the test validation. Model, the development process of implementing the forward design concept, and constantly improve the technical maturity of products.
Shanghai Heng Extension Hydraulic Control Technology Co., Ltd. launched the 'WS-B-type fuel jet electro-hydraulic servo valve' with good performance and reliability, the use of jet-pipe hydraulic amplifier technology, anti-pollution ability. The type of fuel electro-hydraulic The servo valve has good environmental adaptability and can work stably under harsh conditions such as high temperature and vibration, etc. After solving the technical problems such as the stability of jet flow field under high temperature and fuel environment, the zero position stability of the servo valve is greatly improved. Formed a research and development system for the design, process, manufacture, assembly and commissioning, and test and verification of the jet launcher servo valve for aviation.Compared with the electro-hydraulic servo valve products of the professional manufacturers in Europe and the United States, the performance and performance indexes are basically the same Economical, practical on the comprehensive surpass.
Over the years, Shanghai Heng Extension Hydraulic Control Technology Co., Ltd. jet tube electro-hydraulic servo valve research technology has been ranking first in the domestic status, WS-B-type jet electro-hydraulic servo valve shine in the field of aviation. This type of product not only To meet the conventional servo valve performance test, but also need to conduct a variety of harsh environmental tests for assessment.At present, has completed and passed a number of harsh environmental tests.Compared with the European and American manufacturers of fuel servo valve products, reliability , Functional equivalent.Products have been accumulated over the delivery of the type of more than 500 units, successfully applied to all types of pre-research projects.
Aviation fuel servo valve MTBF requirements is 1000000 hours, which means we need to produce a hundred years of service life of the servo valve. As the hydraulic valve spire pearl, the jet fuel electro-hydraulic servo valve technology has been Is the core component of the aircraft, Hengtuo hydraulic will focus on the future series of aviation fuel valves, and increase the reliability, anti-pollution and airworthiness of the research, to do the fuel electric servo valve professional manufacturers, production capacity Servo valve with 100 years.
