Non-woven Fabric Heater Factory Price Introduction:
The heat of the liquid electric heater is generated by the electric heating elements placed inside the heater. The medium is heated through forced convection. The medium enters the container through the container inlet, and when heating, the fluid thermodynamic principle is used to transfer the huge heat generated during the operation of the liquid electric heater. The medium, as a heat carrier, is forced to transfer out through the pump, achieving continuous heat transfer and meeting the requirements of process heating. The liquid electric heater uses liquid as the heat transfer medium, heats up through electric heating, and circulates heat supply through high-temperature water pump forced circulation.
Product Usage:
It is used in heat application occasions where oil is not suitable as a heat transfer medium. The core heating component of the liquid electric heater adopts a tubular bundled structure design. The equipment has fast thermal response, high thermal efficiency, and temperature is controlled by a microcomputer intelligent dual-temperature dual-control method, with PID automatic adjustment and high temperature control accuracy. It is widely used in the heating process of petroleum chemical industry, textile printing and dyeing, printing industry, pharmaceutical medical and other fields with working temperature ≤ 98℃. The main components are configured with high-quality products, long service life, safe and environmentally friendly.
The circulating liquid electric heater heats the fluid through forced convection by a pump, which is a heating method of forced circulation. The circulating electric heater has the characteristics of small size, high heating power, and high thermal efficiency. Its working temperature and pressure are high, with a maximum working temperature of up to 600℃ and pressure resistance of up to 20MPa. The structure of the circulating electric heater is sealed and reliable, without "running, emitting, dripping, or leaking" phenomena. The medium is heated evenly, and the temperature rises quickly and stably, enabling automatic control of parameters such as temperature, pressure, and flow.
Technical Parameters of Liquid Electric Heater:
The liquid electric heater is mainly used for heating liquids such as acid and alkali solutions, chemical reagents, water, oil, etc. It mainly uses stainless steel as the surface metal sheath material, such as 304, 316 stainless steel, etc., with advantages such as high mechanical strength, heat resistance, corrosion resistance, and not easy to scale.
Technical Indicators of Liquid Electric Heater
1. Power deviation: +5~ -10%
2. Cold insulation resistance: ≥50MΩ
3. Insulation withstand voltage: 200V working voltage is 1500V/1min, 380V working voltage is 2000V/1min
Instructions for Using Liquid Electric Heater
3. The working voltage should not exceed 1.1 times the rated value, and the shell should be effectively grounded.
4. The effective heating length must be fully immersed in water to avoid dry burning.
5. The scale on the tube surface should be removed regularly to avoid affecting heat dissipation and shortening service life.
6. The components should be stored in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, it can be heated by reducing voltage or dried in an oven until the insulation resistance is restored.
7. Avoid excessive force when tightening the wiring screws.
Working Process of Liquid Electric Heater:
According to the installation form, it can be divided into horizontal fluid electric heater and vertical fluid electric heater. The heated medium is input by the pump pressure, absorbs heat during the flow process, reaches the temperature required by the user's process, and is sent to the user end. Through the intelligent temperature control device at the outlet and the electric power regulation system, the fluid medium temperature can meet the user's process requirements. At the same time, with the help of internal sensors and various protection devices, once the medium temperature exceeds the set temperature range of the equipment, the intelligent temperature control system will quickly respond, stop the heating operation, and prompt a fault alarm to avoid damage to the heating equipment.
