Detailed Description
The invention is described in connection with the accompanying drawings and the embodiments:
as shown in figure 1, B10 tube drawing lubricating oil winter heating device, the heating device is provided with a PTC heating element 4 installed at an oil outlet of a lubricating oil tank 5, the PTC heating element 4 extends to an oil inlet of an oil pump 6, namely the PTC heating element 4 is arranged in a communication pipeline between the oil outlet of the lubricating oil tank 5 and the oil inlet of the oil pump 6, the PTC heating element 4 is fixed at an oil outlet of the lubricating oil tank 5, the PTC heating element 4 is rod-shaped, a ring-shaped isolation transformer 3 used for heating the PTC heating element 4 is arranged corresponding to the PTC heating element 4, the ring-shaped isolation transformer 3 is a ring-shaped transformer which is manufactured by Zhejiang river strong electric appliances Limited and has the model of BOD-100VA, the ring-shaped isolation transformer is communicated with 220V voltage through an electric leakage protection switch 2 and an air switch 1, and the ring-shaped isolation transformer 3 converts the 220V voltage into 24V.
The annular isolation transformer 2, the leakage protection switch 3 and the air switch 1 are packaged in electric boxes, a switch 8 and an operation indicator lamp 9 are arranged on the electric boxes, before starting up and stretching, the switch 8 is turned on, an oil pump 6 is turned on, other stretching preparation work is carried out in the period, when the system continuously and circularly works for about half an hour, the flow of lubricating oil reaches the stretching requirement, stretching production can be carried out, after 5-10 branch pipes are stretched, the lubricating oil can be heated due to heat generated in the stretching process, the switch 8 can be turned off at the moment, a PTC heating body is turned off, as the heating device adopts safe voltage, the leakage protection switch is arranged at the front end of a power supply, the phenomenon that people are injured by electric leakage can not be generated, the whole heating device is completely immersed into the lubricating oil after being packaged, the internal heating mode is high in heating efficiency, and the stretcher can have working conditions in a short.
The PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency, is automatic constant-temperature and electricity-saving safe heating elements, and has the characteristics that when the oil pump is failed or the oil pump is forgotten to be turned on, the ambient temperature around the heating element rises, the heating element cannot fully dissipate heat, the resistance value of the heating element rises and enters a jump zone, the power of the heating element is sharply reduced, the temperature on the surface of the heating element is maintained at about 250 ℃, and the lubricating oil cannot be burnt by the surface redness of the traditional electric heating tube when the oil pump is failed or the oil pump is forgotten to be turned on.
The circuit part is as shown in figure 1: after a 220V power supply enters an electric box, the electric box is connected with an annular isolation transformer through an air switch-leakage protection switch, 24V alternating current output by the transformer is supplied to a PTC heating rod (12-48V, universal alternating current and direct current, 350W, L =250 mm), and the heating rod is fixed in a proper mode and then inserted into an outlet of the oil box, namely an inlet pipeline of the oil pump.
