    • Says Mr Galdi at SLW type fan

      Says Mr Galdi at SLW type roots blower 3 leaf screw is on the basis of the long manufacturing sales environmental protection fan using new technology to develop new products.

      This machine through on the impeller using the new line, bringing the total thermal efficiency and volume efficiency further, is particularly excellent fan air volume and pressure characteristics.

      The so-called efficiency is good, is fan's calorific value appreciation to decline relative to reduce the temperature, a variety of models used in dry state without becoming dry exhaust pressure force can reach 0.6 KFG per square centimeter.

      Says Mr Galdi at SLW the characteristics of the fan

      1. The spiral shape is 20above way of fixed screw.Into the exhaust shielded wire cut spiral casing, with smooth lines at the top of the triangle rotor into the outlet, should be opened by the rotation of the rotor.The fan into the outlet, do not like old roots spiral fan on or off in an instant, so running sound very small, almost no exhaust pulse.
      2. Because the rotor is three Ye Zhi linear, so it is not like the screw rotor, rotor resulting from axial tiny displacement of the contact with each other.So, only in the section on the guarantee of the gap between the rotor and don't need like spiral rotor coupled with the axial displacement, so that the clearance is too large the fan efficiency is far better than the same size of the screw rotor fan.
      3. Because of its special rotor take shape, easy to maintain mutual clearance between the rotor and to further improve the efficiency.
      4. Due to the use of precision CNC machine batch production of rotor, and the precision management comprehensive measures were taken, therefore, between various turbines have no error performance.In addition, turn the balance in the manufacturing process through strict, so the machine vibration.
      5. Drive gear with high precision, not only to extend life, and realizes low noise.
      6. The output air is clean, do not contain any oil.Not within the case oil lubrication, and adopted to avoid bearing, gear, oil casing with internal structure design.
      7. With the plant quality management, the establishment of production management system, implements the communication between parts, low production cost, short delivery goals the fan in general, have the right amount of inventory, can immediately delivery.

      Working principle of the

      Says Mr Galdi at SLW series environmental protection and energy saving fan, overcame the weakness of the original old roots blower, old two leaf type, 3 leaf type, and the compression principle is the top of the rotor to the vents open a line of instant, the high-pressure air flow outlets and within a chassis, compression of the upstream and compression stress state change violently, the pressure change is the reason of the fan noise.The fan in order to eliminate the factors and spiral shape is studied, so as to achieve environmental protection and energy saving effect.

      The performance of the instructions

      Expressed to fan performance model, diameter, rotational speed, exhaust pressure, air volume and power required for the relationship
      1. Performance represented by air volume is a standard of air into the wind conditions, the so-called standard status, the temperature is 20 ℃, the absolute pressure of 10332 KGF/cm2 (101.3 Kpa) is equal to 65% of humidity.
      2. The benchmark status (0temperature, absolute pressure 10332 KGF/cm2 (101.3 Kpa)) of air volume.General with Nm3 / MLN said, in the wind under the same pressure, under the available type into standard state of air volume.
      Qs standard state air flow (m3 / MLN) Qn benchmark state air flow (m3 / min).
      3. Available under the state of the exhaust air volume type conversion into standard state of air volume.

      Qd: exhaust state air flow (m3 / mi n)
      Pd: exhaust pressure (Kpf/cm2)
      Ts: inlet air temperature (℃)
      Td: exhaust temperature (℃)
      4. With the above results, the exhaust pressure of air volume which according to the performance table to find the fan model, diameter, rotational speed, and power required.
      5. Performance table in a different color shows a different motor power output.
