No power roof fan factory maintenance, Zhenjiang without power roof fan, pass flat fiberglass

 How electric roof fan scheduling valve designed to operate it properly roof fan now has gradually been widely used, the fans also installed electric scheduling valve, easy to operate, the majority of users love, then an electric fan on the roof of the scheduling valve design operation, we know how much we learn more about the next: Roof Fan drive because of its strength from the air, and the compressibility of the air without power roof fan cheap Kuangshuai, necessarily lead to non-response and control stability problems non-powered roof fan, especially in large diameter, large actuators and pressure drop more occasions, require high control precision occasions, to expose its weakness to, there is the issue of speed, due to the larger cylinder gas contents larger gas received from the signal to the actuator to drive the scheduling component, which requires a time in the middle, so the switching time is relatively long, the more big valves, this case is more significant, positive and negative effects of change scheduling valve very easy, just set the built-in module click on OK, and this valve for pneumatic dispatch, it is still a problem called trouble. For large diameter, high torque electric valves require scheduling roof fan, the more cooperative rotary electric actuator without power roof fan factory level, control is not a problem, also recently appeared inverter electric actuator without power roof fan which home, and can progress in the control precision together, and ending energy policy; which one is self-scheduling valves utilize echo signal valve output side, passing to the actuator drives the valve changes the valve opening through the signal tube, The purpose of scheduling arrival pressure, flow, temperature. Proper operation of the electric roof fan scheduling valve design is that, we must be based on the above instructions for proper operation, the only way to fully demonstrate its performance to improve our work efficiency. Expert analysis of two common roof fan failure analysis methods roof fan in the course, there will be too much current and bearing temperature fault, then we analyze the analysis of these two faults. 1. The electrode current or temperature is too high, you should check the following components: ① when driving the intake duct is not shutting the gate or throttle; ② flow exceeds a predetermined value; ③ fan conveying gas density is too large or sticky substance ; ④ motor input voltage is too low or the power single-phase power failure; ⑤ coupling connection errors, aprons too tight or uneven gaps; ⑥ bearing housing affected by severe vibration. 2. If the bearing temperature is too high, you should check the following components: ① bearing box severe vibration; ② grease quality is not lit, deterioration, contains too much dust, sticky sand, dirt and other impurities; ③ bearing cover, seat bolts tight force is too large or too small; ④ axis skew with the rolling bearing mounting, the front and rear two bearing misalignment; ⑤ bearing damage. These are described on the roof of the fan, if you need this product, please feel free to contact us, or to visit the company.
