      Five maintenance methods of jet fan

      Jet fan is mainly used in the longitudinal ventilation system of highway and railway tunnels. The fan is generally suspended on the top or both sides of the tunnel and does not occupy the traffic area. Jet fan manufacturers do not need to build additional air ducts, and the construction cost is low. Economical ventilation. The methods for doing good maintenance on the jet fan are as follows:

      1. The jet fan should be run at least once a month to make the motor bearings well lubricated.

      2. Regularly add lubricating grease, usually once every 12 months. The lubricating grease is Mobil Polytec EM, and the amount of oil is 150 grams per bearing. Oil can be injected with a grease gun from the nozzle of the air cylinder. First, open the oil drain port directly under the motor end cover to drain the waste oil. In the case of bearing oil shortage and direct sales of jet fans, the cause should be investigated and supplemented at any time.

      3. Regularly check the connection bolts of various parts of the jet fan. They must not be loose. Once they are loose, the elastic gasket must be replaced and then locked.

      4. Regularly check the bearings of the jet fan (both the front and rear bearings are NSK-6311 / Z2). When the machine is stopped, move the impeller and listen carefully for any looseness and dry friction of the bearing. If there is any noise, it should be removed in time.

      5. Regularly check the operation of the jet fan. There should be no rubbing, loosening and other sounds. If it should be checked and eliminated, if the vibration becomes large, the cause should be checked and eliminated.


      Jet unloading in tunnel

      a. Determine the location where each fan should be installed, and transport it to this location. Due to the large size, length, and heavy cargo of the fan transport vehicle, there should be 2-3 personnel to direct the traffic in the tunnel, the price of the jet fan, and the vehicle. Should be delayed.

      b. When the fan is delivered in place, remove the fan and place it properly, waiting for disassembly and installation.

      In this process, there should be one crane driver and two cranes operating uniformly, and strictly observe the lifting operation procedures.

      Laying and connecting cables

      The fan leads are concealed by steel pipes and communicate with the cable trench. Check that the cable specifications and designs are consistent with the design and whether the connection phase sequence is consistent with the design drawings.


      Comparison of ejector and blower


      1. Technical comparison:

      (1) Because of the working principle of the ejector, the air, sewage and microorganisms are constantly mixed at the same point for intense contact and mass transfer. The mass transfer process is completed quickly and 100%, and the treatment effect is naturally high. ;

      (2) The oxygen transfer rate and utilization rate of the ejector are high. After 15 minutes, the DO is close to saturation, and the oxygen utilization rate can reach 24%. The gas-liquid mass transfer performance is 10 times higher than that of Roots blower aeration;

      (3) When the jet is oxygenated, the activated sludge (microorganisms) can sufficiently absorb oxygen, and its activity is renewed quickly, the flocculent material particles are large, the sedimentation is fast, the compression performance is good, the mycelium is extremely numerous, dense, and the appearance Clear, no filamentous bacteria.

      (4) Because the jet aeration is a continuous sewage cycle, there will be no dead ends in the sewage, and the treatment effect is naturally guaranteed. The Sichuan jet fan, while the Roots blower aeration is a relatively static flowing water, or there will be Dead ends arise.

      (5) It is also because the aeration of the jet is a continuous sewage cycle, which is more suitable for the impact caused by the change of sewage;

      (6) Using jet aeration, the processing load is relatively increased by 15%;

      2. Comparison in management

      (1) Roots blower air aeration system Because there are many supporting things, maintenance, maintenance and management affairs will naturally increase.

      (2) On the other hand, because the aeration head is microporous, it is easy to be blocked, improper operation and management, and blocked, which is very troublesome, and non-condensation is bad 浦发彩票. The diameter of the jet aeration system is as large as 15mm, and there is no clogging problem at all. In terms of taking 10,000 steps back, because the jet is installed on the water surface, even if it is blocked, it is easy to clear it down.

      (3) There is a regular refueling of the blower, which is also a lot of cost. The poor quality fan may be scrapped after less than 1 year of use.
