Roof ventilators main components: Bracket: made of steel bars imported from Japan, it has a light weight, flexible, does not rust and other properties. Variable angle tube neck: You can change depending on the roof slope angle of the neck factory roof natural ventilation plant, keep in rotation, greatly improving efficiency. Bottom: a waterproof substrate stamping turbine head: the wavy blade circular turbo head design is the best result of scientific computing through. Axis: Stainless steel bottom bracket: The United States closed ubc bearings, lubrication-free natural ventilation plant, long service life. Axial Fan Installation program, methods and technical measures (1) preparation of construction drawings are familiar with the construction process the arrival of the diffusion tube fan, muffler arrival foundation construction control cabinet position to confirm the detection power supply terminal to confirm the detection handling (2) operating points 1) fan Handling Due to the large equipment, steel size and weight, the application of 8 tons limousine transport natural ventilation-free power plant, with 12 tons truck crane for loading and unloading vehicles. In the tunnel according to the actual situation of steel tunnel natural ventilation plant, can pour chain hoist, roll bar and other tools for handling. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Teach you without power ventilation measurement 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 can generally be divided into two categories: 1. Those who can read directly measure directly from the ventilation test instruments measured the size of the measurement parameters, which are direct measurements. Such instruments are sometimes called direct-type instrument. Such as direct measurement using a mercury thermometer fan gas temperature. 2. Indirect measured by a certain function in terms of the size of the desired measurement parameter measurement, called the indirect side interaction. Such as when the ventilation flow, after the first read out by the Pitot tube numerical hydrodynamic its size, and then converted into ventilation flow size. No power plant natural ventilation, natural ventilation plant Qiqihar, Flextronics ventilation provided by Liaocheng Wei Chong ventilation equipment. Liaocheng Flextronics Ventilation Equipment Co. (www.lcwctf.com) (www.lcwctf.com) strong, credible, Shandong Liaocheng fan, ventilation equipment industry has accumulated a large number of loyal customers.
