The water pipeline heater is composed of two parts: the water pipeline heater body and the control system. The heating element is made of 1Cr18Ni9Ti stainless steel seamless tube as protection casing, 0Cr27Al7MO2 high temperature resistance alloy wire and crystalline magnesium oxide powder, which are formed by compression process to ensure the service life of the electric heating element. The control part is composed of adjustable temperature measuring and constant temperature system with high precision digital display temperature controller and solid state relay to ensure the normal operation of electric heater.
Specifications and parameters of water pipeline heater:
(1) Inner cylinder size: Φ100*700mm (diameter * length)
(2) Caliber specification: DN15

(2) Rated power: 8kw
(3) Output voltage: ≤220V (single-phase)
(4) Temperature control accuracy: ±2℃
(5), temperature control range: 0~50℃ (adjustable)
Main structure and working principle
(1) water pipeline heater structure water pipeline heater is composed of a number of tubular electric heating elements, cylinders, deflector and other parts, tubular electric heating elements are placed in the metal tube high temperature resistance wire, in the gap part tightly filled with good insulation and thermal conductivity of crystalline magnesium oxide powder, the use of tubular electric heating elements as heating body, with advanced structure, high thermal efficiency, Good mechanical strength, corrosion resistance, wear resistance and so on. The baffle plate is installed in the cylinder body, which can make the water heat evenly when circulating.
(2) Working principle water pipeline heater adopts digital display temperature regulator, solid state relay and temperature measuring element to form measurement, adjustment and control loop. In the process of electric heating, the temperature measuring element sends the temperature signal from the outlet of water pipeline heater to the digital display temperature regulator for amplification, displays the measured temperature value after comparison, and outputs the signal to the input end of the solid state relay. Thus, the heater is controlled, so that the control cabinet has good control accuracy and adjustment characteristics. water pipeline heater can be started and closed remotely by interlocking device.
