  The installation and correcting operation in the explosion-proof fan possesses different requirements with regard to its content and degree as outlined by the different accuracy requirements, driving solutions, rotation speed in addition to power of a number of explosion-proof fans. Therefore, it is very important to install and find according to the different requirements with the explosion-proof fan.

  1) Clean the surface belonging to the foundation concrete plus check its degree. If it seriously isn't specified, the uneven part may be leveled.

  2) Place the explosion-proof fan base about the foundation, insert a horn involving the cooling & refrigeration fan Manufacturers tomb base surface plus the base surface, and only need to make certain the mortar passes. Use the horn to adjust the exact level so that the explosion-proof group of fans is at a bare level.

  3) As soon as installing a standard explosion-proof fan, several kinds of rectangular horns (steel plates) together with different thicknesses is usually prepared and realigned by several types of overlap. The explosion-proof fan driven through the coupling can be inspected because of the coupling, and the exact level is adjusted.,then fixed by welding.

  The horn is inserted into the two sides of the anchor bolt, and throughout the adjustment of the level, the adjustment bolt is additionally used for adjustment.

  4) The point bolt holes in the anchor bolts passing with the base should be perpendicular to the square holes for any anchor bolts.

  5) In the gap between the particular anchor bolt hole as well as the base and the inspiration concrete, sufficient mortar need to be filled to make certain the strength of the concrete structural fellow member.

  When installing a explosion-proof fan by using important or large precision requirements, the mortar should be filled into the hole from the anchor bolt very first. After it is fully hardened, it needs to be re-aligned and adjusted towards level. After the installation accuracy will be met, the mortar is going to be added. The gap involving the base as well as the foundation stick.

  6) Following the mortar is thoroughly hardened, tighten the nut belonging to the anchor bolt.

  YOU. Start the inspection with the Roots blower

  Prior to a Roots blower begins, the appearance on the Roots blower is necessary. Check whether the Roots blower shape and Exhaust Fans Manufacturers accessories are complete along with the circuit is regular. Before starting, firstly guarantee that the Roots blower appears to be good.

  2, begin the Roots blower amenable vent valve : start

  Start the actual vent valve 1st, then press the button to start the Roots blower, await the Roots blower to stabilize, then in close proximity the vent valve.

  3, start the view meter in the Roots blower

  Following the Roots blower is started, the instruments and equipment from the Roots blower ought to be inspected so the instruments belonging to the Roots blower are working properly.

  4, stop the opening on the Roots blower control device

  In the case from the normal operation in the Roots blower, first open the vent valve and also avoid the bunny directly disconnecting the power supply of your Roots blower.

  A FEW, stop the power outage on the Roots blower

  After opening the in-take valve, the Roots blower runs slowly after which stops at this time. After stopping, check the portions of the Roots blower to see whenever a looseness, too loosely belt and too tight belt.

The particular basic principle of choosing the

  We have also talked a lot about the common knowledge of axial fans. Then let us discuss the principle of selecting axial devotees. Please see the detailed synopsis below:


  1 Before selecting some sort of fan, you should know your production and product quality status of domestic ventilators, such as the species of ventilator, the standard and the special using various products, and understand the current domestic fan market.


  2 In line with the physical and chemical properties with the gas transported by the ventilator, select the ventilator for different utilizes. Such as the selection regarding explosion-proof ventilator with explosive plus flammable gas, determine the required explosion-proof level requirements for your fan; dust or pulverized coal ventilator must be selected for dust discharge or perhaps transport of pulverized coal; anti-corrosion ventilation should be selected for transport of corrosive unwanted gas Machine, determine whether the anti-corrosion material is made of FRP or PP; in high temperature applications, high temperature gas really should be selected for high temperature fuel, and the ambient temperature along with the temperature of the transport gas should be known.


  3 When there are more than two types of ventilators readily available selection on the ventilator collection function chart, priority should be provided to selecting one with larger power, smaller machine number and also larger conditioning scale. Of program, it can be compared with regard to cost performance. Weigh the pros and cons and decide.

  4 If the diameter from the selected fan impeller is much larger compared to diameter of the original buff, in order to utilize the original motor shaft, bearings and bearings, it is crucial to start the motor, the strength in the original components of the fan and the criticality of the shaft. The rate is calculated.


  5 When picking a centrifugal fan, when the motor power used is not as much as or equal to 75 kW, the External Rotor Fans Manufacturers valve for starting only is probably not installed. When selecting a centrifugal boiler induced draft fan for high-temperature flue energy or air, a start-up valve should be provided to prevent overload during cold operation.

  6 For air flow systems with noise requirements, the ventilator with high strength and low impeller circumferential speed need to be selected first, and it really should be operated at *** power place; it should also be depending on the noise and vibration transmission method generated by ventilation system. Sound and vibration reduction measures. For the vibration reduction measures of the ventilator and the motor, the vibration damping base is usually generally selected, and different damping devices are selected based on the fan device method.


  SIX When selecting a fan, try and prevent the fan from becoming connected in parallel or within series. When it is unpreventable, the axial fan should select exactly the same type of fan with exactly the same function. When series connection is selected, there must be some pipe joint between the class ventilator along with the second stage ventilator.
