Zhenjiang BAIC Plant Ventilation Hanger, Butterfly Valve Electric Butterfly Valve Project
Shanghai Dongfeng Pump and Valve Factory recommends a crane butterfly valve electric butterfly valve product, which is mainly used in the ventilation system of the plant of Zhenjiang Beiqi Factory. The crane butterfly valve electric butterfly valve has good vibration isolation effect and noise reduction effect.
Introduction to factory crane, butterfly valve and electric butterfly valve:
Use C R. Shockproof, long service life. The suspended outer frame is sprayed with plastic. The butterfly valve is designed with low frequency value. It can effectively isolate low-frequency noise caused by vibration. It is suitable for all kinds of fans, air conditioning boxes, air ducts, water pipes, fan coil units and other lifting vibration reduction!
Factory crane. Butterfly valve electric butterfly valve uses the upper and lower hook series hanging shock absorber, which is widely used as a lifting equipment. The butterfly valve shock absorber has large damping, low natural vibration frequency, easy installation, and obvious effect on eliminating solid sound transmission. It is suitable for hanging installation of equipment and pipeline systems of all sizes!
Ventilating crane, butterfly valve and electric butterfly valve are mainly applicable to various hoisting equipment such as suspended air conditioners, exhaust and supply fans, axial flow fans, fresh air fans, pipes, etc. Load range: 5-1000Kg!
Air exchange cranes, butterfly valves, and electric butterfly valves are mainly used for vibration reduction of small equipment such as fan coil units. During the installation of central air conditioners, the vibration reduction installation of fan coil units can improve the operating condition of fan coil units, extend their service life, and reduce noise and vibration pollution to the surrounding environment. Songjiang Group has designed and produced the HS type fan coil special shock absorber according to the actual installation requirements of fan coil units. This product has large damping, low natural vibration frequency, convenient installation, and low cost. It is not suitable for installation in places with high requirements for human settlements. The vibration damping installation of fan coil units can refer to the Installation of Fan Coil Units (01 (03) K403) of the architectural standard design drawings!
Introduction to ventilation system of Zhenjiang BAIC Plant:
Ventilation is a kind of building environment control technology to control the spread and harm of air pollutants and achieve indoor and outdoor air environment quality assurance by means of ventilation dilution or ventilation elimination. Ventilation system is a complete set of devices to realize the function of ventilation, including air inlet, air outlet, air supply duct, fan, cooling and heating, filter, control system and other auxiliary equipment. System functions:
1、 Renew the indoor air polluted by living and living process with outdoor fresh air to maintain the cleanliness of indoor air to a certain low standard level 2、 Increase internal heat dissipation and prevent discomfort caused by wet skin. Such ventilation can be called thermal comfort ventilation 3、 When the indoor air temperature is higher than the outdoor air temperature, the building components will be cooled. This kind of ventilation is called building cooling ventilation. Classification of ventilation system of Zhenjiang BAIC Plant:
Classification by ventilation power: natural ventilation, mechanical ventilation; According to the ventilation service scope: general ventilation, local ventilation;
Classification according to air flow direction: air supply (inlet) and exhaust (smoke); Classification by ventilation purpose:
General ventilation, hot air heating, detoxification and dust removal, accident ventilation, protective ventilation, building smoke control, etc; Classified according to the location of power: power centralized and power distributed.
BAIC Plant Introduction:
"BAIC Group" is the abbreviation of the original "BAIC Group Corporation", which was changed into the current "BAIC Industry Holding Co., Ltd." in September 2000 and renamed as "BAIC Group Co., Ltd." in November 2010. BAIC Motor Corporation Limited (hereinafter referred to as BAIC Motor Corporation Limited) was founded on September 28, 2010, and is jointly sponsored by BAIC Motor Corporation Limited, Beijing Steel Co., Ltd., Beijing State owned Assets Management Co., Ltd., Modern Innovation Holding Co., Ltd., Beijing State owned Assets Management Center and Beijing Energy Investment (Group) Co., Ltd, With a registered capital of 5.6 billion yuan and a total number of employees of more than 22000, the company is a platform for BAIC Group to aggregate the resources of passenger cars and develop its business. It is also a key enterprise supporting development in Beijing. [1] Beijing Jeep has been transformed into Beijing Benz (there will be no name of Beijing Jeep Company in the future). Beijing Benz, Beijing Hyundai and Beijing Foton are all called "three major sectors of Beijing automotive industry" under the leadership of "BAIC Holding". BAIC Group Co., Ltd. (hereinafter referred to as "BAIC Group"), headquartered in Beijing, is one of the five major automobile groups in China. It is mainly engaged in vehicle manufacturing, parts manufacturing, automobile service trade, research and development, education, investment and financing, and is the development planning center, capital operation center, product development center, and talent center of Beijing automotive industry. BAIC Group, guided by the scientific outlook on development, further strengthens its control over strategy, operation and capital in accordance with the new strategy of "taking the road of collectivization and achieving leapfrog development". It has successfully built five development platforms, including vehicle manufacturing, parts development, independent research and development, service trade, and reform and adjustment. It is a complete automobile group in China's automobile product category.
Shanghai Dongfeng Pump and Valve Factory recommends a crane butterfly valve electric butterfly valve product, which is mainly used in the ventilation system of the plant of Zhenjiang Beiqi Factory. The crane butterfly valve electric butterfly valve has good vibration isolation effect and noise reduction effect.
Adding an electric butterfly valve to the reciprocating structure can make the following five obvious changes:
1. Reciprocating starting stage. For linear reciprocating drive mechanism added with elastic energy storage device, such as starting according to working frequency and stroke, the demand for motor thrust is increased in the starting energy storage stage, and the energy consumption is large. But it can be solved by "swing control algorithm".
2. In the reciprocating operation phase with working frequency and stroke, whether in the acceleration phase or in the braking deceleration phase, the elastic energy storage device effectively reduces the demand for motor driving force and plays a role in boosting energy conservation. Single cycle energy saving and dyeing efficiency is remarkable, and subsequent tests show that the energy saving and dyeing efficiency can reach more than 50%. The overall energy saving increases with the increase of running time of M, which has great potential.
3. To achieve the same frequency of reciprocating drive, the elastic energy storage boost system is adopted, which can effectively reduce the demand for motor driving force and save energy A consumption for a long time in the process of equipment use. On the other hand, small motors and actuators can be used, which reduces the cost of system procurement.
4. Under the condition that the stroke and load mass are unchanged, the same driving thrust can make the reciprocating motion mechanism with electric butterfly valve reach the goal. The high motion frequency is higher than that without electric butterfly valve, which improves the working efficiency of the system and realizes the high-speed equipment.
5. The electric butterfly valve added to the reciprocating mechanism can effectively reduce the impact, vibration and noise of the system.
