How to control the heating speed of flange heating tube

It depends on the structure of the heater. The inverter can only change the AC frequency, thereby changing the rotation speed of the motor to achieve the purpose of changing the motor output power. Moreover, the heater does not rotate, and the frequency conversion cannot control the heating speed. The diode half-wave rectification is used to change the effective value of the AC to achieve the purpose of changing the heating power and heating speed; this method is used most, the circuit structure is simple and easy to operate.

Transformation, using a small transformer to transform, the advantage is that it can be adjusted in multiple gears, the disadvantage is that the circuit structure is relatively complex and the manufacturing cost is high. The energy-saving effect is significant, and almost 100% of the electric energy is transferred to the heating medium. The electric heating pipe is a stainless steel structure as a whole. Except for the connecting flange, all other parts are stainless steel. The electric heating pipe is supplemented with a thickened polyurethane foam insulation layer to reduce the insulation temperature of the stainless steel liner and the stainless steel shell, maintain the hot water temperature, and save electricity.

The flange heating pipe is small in size and high in power: the heater mainly uses a clustered tubular electric heating element. Fast thermal response, precise temperature control, and high comprehensive thermal efficiency. High temperature heating: The maximum temperature of the heating furnace is designed to be 850℃. 4. The outlet temperature of the medium is uniform and the temperature control is accurate. Wide range of uses and strong adaptability: This product can be used in explosion-proof or general occasions, and the explosion-proof level can reach dⅡB and C levels. The pressure resistance value of the air heating furnace is 20MPa.

Long life and high reliability: This heater is made of special electric heating materials, with low design surface power and multiple protection measures, which greatly improves the safety and life of the electric heater. Fully automatic control: According to needs, through the heater circuit design, it is easy to realize the automatic control of parameters such as outlet temperature, flow rate, pressure, etc., and can be connected to the computer.

This product has the characteristics of heat preservation, pressure resistance, moisture resistance, etc., and is safe and reliable to use. Reasonable flow field direction design, uniform heating, no high and low dead corners, and high thermal efficiency. The explosion-proof pipe electric heating tube is equipped with a thermostat. The mechanical thermostat below 50KW (preset high temperature 6O℃, low temperature 45℃), 50KW and above (including 50KW) is an intelligent digital temperature controller, and the user can set the temperature by himself. The overheat protector (the default setting is 90℃) is used to control the water temperature, prevent water shortage and overheating, and prevent damage to components and systems. The flameproof pipe electric heating tube is very convenient to repair. You only need to open the sealing cover and unscrew the nut on the flange to take out the electric heating tube.
