Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. Teach you without power ventilation measurements is the use of so-called measuring instruments, or work it to the side of a given size of a physical quantity by a certain method. As measured by liquid column manometer pressure ventilators, centrifugal ventilators tachometer measuring speed. Measurement methods generally fall into two categories: 1. Those who can read directly measured directly from the ventilation test instruments most of the measured parameters of the size of the measurement, which are direct measurements. Such instruments are sometimes called direct-type instrument. Such as direct measurement with a mercury thermometer fan gas temperature. 2. Indirect measured by a certain function in terms of the size of the desired measurement parameter measurement, stainless steel roof ventilators, called indirect side each other. Such as when the ventilation flow rate, after the first value is read out by the Pitot tube the size of its dynamic pressure, and then converted into the size of the flow ventilation. Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. No power ventilation function: 1, automatic extraction plants, heat and moisture, dust, odors, smoke, odors and other chemical raw materials of the house, so that fresh air, comfortable. 2, effectively reducing indoor, warehouses, workshops or factories in the temperature of 2-3 degrees, to avoid the summer heat stress and irritable mood, reduce the impact of high temperature on the storage of products or raw materials. 3, according to the natural climate automatic ventilation operation, no power, saving energy and money. Family Residential one-time investment of several decades Bai yuan can enjoy the comfort, factories, warehouses investment installation can save a lot of power consumption, and the effect is significant Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fans and so on. Axial fan manufacturers introduce structural characteristics of mixed flow fan oblique flow fan impeller centrifugal and axial air doing sports, arc-shaped roof ventilators, axial fans and centrifugal fans between is between, using accelerated method Meridian and "quasi-Three" Francis fan design flow theory using tapered wheel structure, twist the wing blade, air inlet plus home collector or curved silencer. Wind volume, compact structure, low noise, high pressure, high efficiency, easy installation, the advantages of small volume, etc., by the diagonal flow fan casing, impeller, motor, import collector outlet guide vanes and other components, chassis using cylindrical, divided into three flange connection into a whole, export import along the stream network connection, the arc-type roof ventilation, air inlet header sword is made of retractable streamlined, the overall structure of the network equipped with sound-absorbing panels composed of outlet is equipped with deflector, the outlet stream with good air distribution, support of steady pressure. Oblique flow fan as ventilation use, generally used in indoor ventilation factories and buildings, as both an input gas, also used as an exhaust gas, but when used, Handan roof ventilators, air gas can not contain viscous material, contained in the dust and hard particles is not greater than 150mg / m3, gas temperature should not exceed 80 ℃ matrix roof ventilation, Flextronics ventilators (certified), Handan roof ventilation ventilated by the Liaocheng Flextronics Equipment Limited. Liaocheng Flextronics ventilation equipment (www.lcwctf.com) (www.lcwctf.com) is an industry leader in Shandong Liaocheng, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Flextronics ventilation in leadership with the staff warmly welcome all inquiries negotiations to create Flextronics ventilation a better future.
