In the process, the whole-pipe stress removing device comprises a plurality of medium-frequency induction heating devices, the plurality of medium-frequency induction heating devices realize staged heating of the coiled tubing and finally heat the coiled tubing to a required specified temperature value, and the whole production line is stopped and interrupted due to the fact that one medium-frequency induction heating device breaks down frequently, so that the coiled tubing is failed to be manufactured, and great economic loss is generated.

Therefore, a fault self-starting system for the machining process of the coiled tubing is urgently needed, and when one medium-frequency induction heating device breaks down, the whole device does not need to be stopped.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an it is not enough that prior art is overcome to the purpose, provides a trouble self-starting system is used in coiled tubing processing, through two firing equipment, a normal heating, and normal firing equipment once only heats required assigned temperature, and a reserve, when realizing breaking down, need not the purpose of shutting down. When normal heating equipment breaks down, the current power of the heating equipment is collected and transmitted to standby heating equipment through the control system, and the function of temperature stabilization after self-starting can be realized.

The purpose of the utility model is achieved through the following technical measures: a fault self-starting system for machining a continuous oil pipe comprises a human-computer interaction interface, a programmable controller, heating equipment and standby heating equipment, wherein the human-computer interaction interface is used for monitoring the running state and parameters of the system in real time and is connected with the programmable controller, the other end of the programmable controller is respectively connected with the heating equipment and the standby heating equipment, the heating equipment is connected with the standby heating equipment in parallel, the programmable controller is used for signal acquisition and logic operation control, when the system is normally used, the system is heated to a specified temperature through the heating equipment at one time, and the standby heating equipment is standby.

The system comprises a human-computer interaction interface 1, a programmable controller 2, heating equipment 3, standby heating equipment 4, a continuous oil pipe 5 and a heating coil 6.

Detailed Description

An embodiment, as shown in fig. 1, is a fault self-starting system, including a human-computer interaction interface 1, a programmable controller 2, a heating device 3, a backup heating device 4, where the human-computer interaction interface 1 for monitoring an operation state and parameters of a device in real time is connected to the programmable controller 2, the other end of the programmable controller 2 is connected to the heating device 3 and the backup heating device 4, the heating device 3 is connected in parallel to the backup heating device 4, the programmable controller 2 is used for signal acquisition and logic operation control, and when the system is in normal use, the system is heated to a specified temperature by the heating device 3 at one time, and the backup heating device 4 is in backup.

The heating device 3 comprises a heating power supply and a heating coil 6, one side of the heating power supply is connected with the programmable controller 2, and the other side of the heating power supply is connected with the heating coil 6.

When the heating device 3 fails, the current power of the heating power supply is recorded by the programmable controller 2, and is transmitted to the standby heating device 4, and the standby heating device 4 is started.

The minimum power of the heating device 3 and the backup heating device 4 is selected according to the heating temperature requirements of different coiled tubing 5.
