HBL type constant power parallel constant power Electric tropics

Wuhu Heng Xin Cable Co., Ltd. is a professionalElectric Heat Tracing Factory, the production of various models of self-limited temperature heating with the tropics, constant power with tropical, solar energy with tropical, explosion-proof electric companion tropical, anti-corrosion with tropical, flame retardant Electric tropics, heat-tracing composite pipe, cable and all kinds of ancillary equipment, to provide users with storage tanks, pipeline electric heating insulation scheme design, product manufacturing, engineering installation, after-sales service.

HBL typeParallelConstant power in the tropics because of its multiple heating joints in the whole length of parallel connection, it is referred to as the parallel typeConstant Power Electric Tropics。

1. Product model:

Example: A. HBL2 (Q)-j3-30 represents a single phase-enhanced constant-power parallel electric tropics with a power of 30W per metre

B.HBL3 (Q)-j3-40 represents a three-phase power parallel electric tropics with a power of 40W per metre.

2. Product structure and working principle

(1) Constant power parallel electric-tropical structure (see figure one or two)

Figure I: HBL2-type constant power parallel electric tropical structure schematic diagram

Figure II: HBL2 constant power parallel electric tropical structure schematic diagram and electrical schematic diagram

(2) Working principle

The power supply bus is two or three parallel insulated copper conductors, and on its surface around the heating wire, and the electric wire at a certain distance ("that is, heating festival length") and bus connection, forming a continuous shunt resistance, bus power, the shunt resistance heating, thus forming a continuous heating belt.

5, Product characteristics

Constant power parallel heating unit length of heat is constant, the longer the use of the electric belt output of the total power greater. The electric tropics can actually require arbitrary length shearing at the scene. In addition, due to the flexibility of the electric tropics, it is easy to cling to the surface of the pipeline, the electric heating layer of metal cover net can prevent electrostatic generation and safe grounding, it not only enhances the overall strength of the electric tropics, but also plays the role of heat transfer and heat dissipation.

Constant power parallel to the heating and temperature controller with the use of. The medium temperature of the pipe or heating body can be maintained accurately.

Enhanced typeConstant Power Electric TropicsIt is a layer of insulating layer in the ordinary type of electric tropics, and the remaining structure is the same as that of ordinary electric heating. The main characteristics of the enhanced type of electric tropics high mechanical strength of ordinary type electric tropics, strong anti-corrosion ability, but the thermal conductivity is slightly low, it is mainly used in the underground pipeline and corrosive gas occasions, because the Bus section area is limited, in order to avoid buck too large, so the single point of power supply one-way output when the maximum length has a certain limit, when the single point power supply two-way output , the length of use can be increased by one fold (see table I, figure IV). If you need to heat the pipeline longer, you can use a multi-point power supply, or the use of our company's HCL-type series of electric tropical (introduction see later Page).

Figure IV: Single Point power supply bidirectional output graph

In addition to the characteristics of single-phase electric Tropics, the three-phase electric tropics also has the characteristics of maximum length of use, good heating uniformity and balanced load of power network.

Installation of electric heating and control of electrical appliances generally have overload, short, leakage, overheating protection.

6, Product application occasions:

The electric belt mainly uses in the pipeline, the valve, the pump body, the storage tank, the reaction tower, the instrument box and so on antifreeze and the heat preservation, or maintains the instrument pipeline the craft temperature. The specific application occasions include:

(1) in the normal situation of continuous flow of low solidification pipeline use, can avoid the media due to stop the flow and solidification.

(2) The need to strictly control the operating temperature of the liquid pipeline with heat and heat preservation.

(3) Cold frozen area water pipe line and valve antifreeze, drainage pipes and condensate pipeline freezing.

(4) The offshore platform pipeline antifreeze.

(5) General pipelines and meters with thermal insulation.

(6) wellhead oil recovery shaft with heat (replace water jacket), sewage well with heat.

(7) Airport runway to prevent ice and snow frozen.

(8) Concrete products antifreeze maintenance.

7, Explosion-proof Description:

Electric belt according to gb3836.1-2000 and gb3836.3-2000 explosive environment with explosion-proof electrical equipment, "general requirements" and the installation requirements of safety-oriented electrical design and manufacture. Anti-explosion level of "E ll t3-t6", explosion-proof certification number CNEX02, 433U. Products with fire-retardant, with an increase in safety of electrical accessories, applicable to the direct impact of external forces of the factory area, two areas of explosive gas mixture "T3-T6" group sites.
