Abstract
The utility model relates to a constant-temperature electric heater, comprising a plurality of heating tubes, which are arranged on a suspending plate, wherein the tail end of each heating tube is fixed on a heater fixing flange, a power line of each heating tube is connected with a wiring board which is fixed on a wiring board fixing flange, and a sleeve is arranged between the rear end surfaces of the wiring board fixing flange and the heater fixing flange; and a cylinder is sleeved on the wiring board fixing flange, and a cover plate is arranged at the rear end of the cylinder. The constant-temperature electric heater disclosed by the utility model integrates an electric control device in a wiring box, can automatically start or stop controlling the temperature of an oil tank as long as the power is supplied, does not need to be controlled externally and keeps constant-temperature control; and a temperature-measurement switch is arranged below a heating tube from a certain distance so that the measured temperature is basically equal to the temperature of the oil tank and the accuracy of temperature control is improved, wherein a first temperature-control switch is switched on when the temperature is smaller than 38 DEG C and is switched off when the temperature is larger than 42 DEG C so that the temperature-control switch is regulated; and a second temperature=control switch is switched off when the temperature is larger than 80 DEG C and can manually reset.
Description
Technical field
The utility model relates to a kind of constant temperature electric heater.
Background technology
Usually use liquid in the electric heater heating container, like the oil in the fuel reserve tank.Generally measure the oil temperature through the temperature sensor that is arranged on the fuel tank, electric control box is controlled the duty of electric heater according to measured oily temperature.
It is split type that existing container uses the temperature element and the heating element of electric heater, inconvenient installation, and security is lower; Therefore, how addressing this problem, is the technical barrier of this area.
The utility model content
The technical matters that the utility model will solve provide a kind of simple in structure, with temperature element and heating element are integrated, security is higher constant temperature electric heater.
For solving the problems of the technologies described above; The utility model provides a kind of constant temperature electric heater; It comprises: be located at a plurality of heating tubes on the boatswain chair, the end of each heating tube is fixed on the well heater mounting flange, and the power lead of each heating tube links to each other with terminal block; Terminal block is fixed on the terminal block mounting flange, is provided with sleeve between the rear end face of this terminal block mounting flange and well heater mounting flange; Be arranged with cylinder on the terminal block mounting flange, the rear end of this cylinder is provided with cover plate.The below of each heating tube is provided with the temperature element that links to each other with said terminal block; During work, heated air rises, and makes this temperature element be difficult for the influence of heated air; And only receive heat radiation from heating tube; Therefore, temperature that it records and fuel tank temperature basically identical have improved the accuracy of temperature control.
During practical implementation, comprise on the said terminal block: the relay of first, second temperature detect switch (TDS) that is used for the design temperature range of control and the power supply that is used to control heating tube; First, second temperature detect switch (TDS) and relay are connected successively.
As a kind of embodiment, said first temperature detect switch (TDS) is connected during in temperature＜38 ℃, breaks off in the time of＞42 ℃; Second temperature detect switch (TDS) breaks off during in temperature＞80 ℃, so that temperature is controlled at required scope.
The utlity model has positive effect: the constant temperature electric heater of (1) the utility model, integrated electrical control equipment in the electric heater junction box only needs supply power, constant temperature electric heater just automatically start-stop control the fuel tank temperature.Do not need external control, keep thermostatic control; (2) constant temperature electric heater of the utility model is installed in a certain distance of heating tube below with temperature element, makes its temperature that records and fuel tank temperature basically identical, has improved the accuracy of temperature control; Wherein, first temperature detect switch (TDS) is connected in the time of＜38 ℃, breaks off in the time of＞42 ℃, and is adjustable; Break off hand-reset during second temperature detect switch (TDS)＞80 ℃.
