Embodiment 1

[0015] An installation process of an explosion-proof electric heater, characterized in that: the explosion-proof electric heating rod is installed horizontally, the installation nipple is welded on the oil tank, and the electric heating rod is connected through the installation nipple The flange is installed on the tank body, and an oil-resistant asbestos rubber pad is provided between the two flanges, which are fastened with bolts. The explosion-proof electric heater is provided with a junction box, and the junction box is fixed on the human body with a mounting bracket. Outside holes or openings, to prevent volatilized oil and gas from entering the junction box, the highest installation position of the electric heating rod must be controlled below the minimum working liquid level of the oil tank process design, and a bracket is added to the electric heating rod inside the tank. The bracket is prepared by the user. The center of the rod body is about 150mm away from the bottom...

Abstract

The invention discloses an explosion-proof electric heater installing process, which is characterized by comprising the following steps that an explosion-proof electric heating rod is in horizontal installation, an installation nipple is welded on an oil tank, the electric heating rod is arranged on a tank body through a connecting flange arranged on the installation nipple, an oil-resistant asbestos rubber pad is arranged between two flange plates and is connected and fastened through screw bolts, an explosion-proof electric heater is provided with a junction box, the junction box is fixedly arranged outside a manhole or an open opening through an installation support frame, the highest position of the installation of the electric heating rod needs to be controlled to be below the lowest work liquid level of the oil tank process design, a bracket is added in the tank for the electric heating rod, the bracket is prepared by a user, the distance from the center of a rod body to the tank bottom plane is 150 mm, and the rod body is fixed by the support frame. The explosion-proof electric heater installing process has the advantages that a heat system is simple, the number of water supply pumps is small, the operation is convenient and reliable, the monitoring workload is small, the service life is long, and explosion cannot easily occur.

Description

technical field [0001] The invention relates to an electric heater, in particular to an installation process of an explosion-proof electric heater, which belongs to the field of heater manufacture. Background technique [0002] There are two reasons for the ignition of flammable gas mixtures by electrical equipment: one is the sparks and arcs generated by electrical equipment, and the other is the heating of the surface of electrical equipment (that is, the surface in contact with flammable gas mixtures). The parts that can generate arcs and sparks during normal operation of the equipment are placed in the flameproof enclosure, or other explosion-proof types such as potting type, sand-filled type, oil-filled type or positive pressure type can be used to achieve the purpose of explosion-proof. For the increased safety electrical equipment, it is the equipment that will not generate arcs, sparks and dangerous high temperatures during normal operation. If some protective measur...
