The invention discloses a
heating system for a centralized
lubrication pipeline and a usage method. The
system comprises a terminal strip,
electric heating nets, return lines, connecting rings, external heating wires, a
temperature control switch, a
contactor, a
timer, a
heating power supply and a
circuit breaker, wherein the
electric heating nets of all oil pipelines are connected in series sequentially through the terminal strip; the
electric heating nets are arranged inside the oil pipelines; the return lines are parallel with and insulated from the electric heating nets; the connecting rings are arranged at two ends of each oil pipeline; the
temperature control switch is used for controlling connection of the power supply; the
contactor is controlled to be connected with the power supply; the
timer is responsible for setting of cycles and time; and the
circuit breaker plays a role in protection. The electric heating nets, with which the pipelines are sleeved, are electrically connected in series, and the power supply is switched on under the control of the
temperature control switch so as to heat the whole pipeline. The method is even and synchronous in pipeline
heating effect, one power supply can drive heating of all the
branch pipelines, the
heating efficiency is high, and the cost is low; and the
heating power supply can be adjusted according to specific conditions of the pipelines after laying, so that the method can meet requirements under different conditions more flexibly as well as meet requirements of pipeline transformation in the future.
