      Tianjin Blower Group Co., Ltd. is a professional manufacturer of various fan designs and manufacturers. The company has engineering and technical personnel, advanced processing equipment, production technology and perfect detection methods and management systems, strong technical force and stable product quality.

      The high-pressure fan itself also generates a certain temperature when it is operating normally, but that is normal. However, there are also some reasons that cause the high-pressure blower temperature to be high. The main reasons are as follows:

      (1) Poor lubrication quality. The purpose of lubrication is to prevent the dynamic and static parts from directly contacting each other to generate friction, and to form a friction between solid and liquid. If the quantity of lubrication is insufficient or the quality is poor, the dynamic and static parts will be directly heated by friction, or the heat cannot be taken away by the lubrication, and the high-temperature fan bearing temperature will rise.

      (2) Poor assembly of rolling bearings. If the tightness between the inner sleeve and the shaft is insufficient, the gap between the outer sleeve and the bearing seat is too large or too small.

      (3) The sealing felt is too tight and generates heat.

      (4) The bearing of the high-pressure blower is too large to bear the impact load, which seriously affects the stability of the lubricating film.

      (5) Insufficient or interrupted cooling water in the bearing of the high-pressure blower, which affects the generation of heat and raises the bearing temperature.

      (6) The quality of high-pressure blower bearings is poor. The quality of the sliding bearing is poor, and the contact of Ugin is not good or the child is born; cracks, chipping, peeling, etc. on the rolling bearing surface of the rolling bearing will destroy the stability and uniformity of the oil film, and the surface will cause the bearing to heat up.

      Does the size of Roots blowers have to do with air volume?

      1.Roots blower speed

      In many places of ventilation, the Roots blower is not very high in speed, but the air volume of the blower in operation and its speed are indeed inseparable, and the speed of the blower will also affect the air volume. In general, the speed is directly proportional to the air volume of the blower. If the speed of the air blower is large, the volume of the air blower will also increase, and vice versa. It can not be said that the air volume of the blower is related to the rotational speed, but it is also necessarily related.

      2.The size of the air inlet and outlet of the three-leaf roots blower

      As mentioned above, the air volume of the blower is related to the speed. There may not be such blessings at the air inlet and outlet of the blower. When the air inlet of the blower becomes smaller, the air volume will also decrease, and the pressure of the blower will be the same If the air inlet becomes larger, the air volume of the blower will change a little, the air pressure of the blower will also be small, the large air volume of the air outlet will increase, and vice versa, but the air pressure of the blower will increase. Therefore, the size of the air inlet and outlet will affect the air volume and the wind pressure of the fan will also be affected.

      3.Blower rotor

      This is definitely related. The operation of the blower relies on the rotor. The frequency of the blower's rotor determines the amount of air flow of the blower. Since the size of the blower's rotor is fixed, if the rotor and the blower are fixed, The distance between the casings should be 0.01mm or smaller, the air volume obtained by the blower will increase, and the pressure will increase accordingly. Due to technical limitations and various factors such as the life and safety of the blower, they will be formulated in accordance with unified standards.

      The air volume required for tunnel mechanical ventilation should be calculated based on reducing the harmful gas concentration in the tunnel to an allowable value within the allowable ventilation time after the train passes through the tunnel, and the piston action between trains should be considered. The allowable concentration of harmful gas is calculated as not more than 30 mg / m3 when hauled by steam locomotive. When using internal combustion engine traction, currently it can be calculated no more than 2 mg / m3. For tunnels in plateau areas, the sensitive effects of harmful gases on the human body should be considered. The allowable time for tunnel ventilation should generally be calculated based on the interval between the exit of this train and the entrance of the next train, but not more than 15 minutes.
