Installation and debugging of horizontal explosion-proof electric heater

Explosion-proof electric heater is a kind of equipment used in explosion-proof occasion to convert electricity into thermal energy. It is used to heat, heat and heat the liquid, gaseous and solid medium of flow or stationary.

The fluid explosion-proof electric heater is a kind of electric energy conversion to heat energy to heat the material to be heated. In the work of low temperature fluid through a pipe under pressure into the input port, along the electric heating container specific heat flow path using fluid thermodynamic principle, take heat energy generated in the heating element, the heating medium temperature, high temperature medium electric heater export process requirements. The electric heater internal control system according to the automatic regulation of the heater power output temperature sensor signal output port, the output port of the uniform medium temperature; when the heating element overheating, overheating protection device independent of the heating element immediately cut off the heating power, heating the material to avoid overheating caused by coking, metamorphism, carbonization, leading to severe fever element burn, prolong the service life of the electric heater.

install

Horizontal explosion-proof electric heater is horizontal installation mode, and the outlet should be vertical upward. Before and after export, there must be more than 0.3 meters straight pipe section and a bypass pipe should be installed. In order to meet the needs of electric heater inspection and seasonal operation.

The electric heater is installed before using 500V tramegger insulation resistance detection terminal and the shell of the main wiring, insulation should be more than 1.5M Omega, electric heater insulation resistance should be greater than or equal to 10M, and the body and the parts have no checker defects.

The control cabinet produced in this factory is non explosion-proof equipment. Should be installed in the explosion-proof area (outside security area) should be installed by a comprehensive examination and correct wiring.

Electrical wiring must meet the requirements of explosion-proof, cable must be selected copper core wire and connection nose connection.

The electric heater is equipped with a special earthing bolt. The user should connect the grounding wire to the bolt. The grounding wire should use more than 4mm2 or more copper wires, and the grounding resistance should not be greater than 4 ohms.

debugging

Before the trial operation, the system should be checked again to check whether the power supply voltage is in conformity with the nameplate.

According to the instructions of the use of the temperature regulator. Set the temperature fixed value according to the technical requirements.

Overheating protection device of electric heater has the specified temperature set by explosion. There is no need to adjust.

First open the pipeline valve, close the bypass valve, exhaust the heater air, when the medium is full, the electric heater can start. Note: absolutely prohibit the electric heater to burn!

According to the operation instructions of the random drawings and documents, we must operate correctly and record the relevant data such as voltage, current and temperature at run time. We can arrange the official operation for 24 hours without exception.
