Heating system for centralized lubrication pipeline and usage method

Abstract

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.

Description

technical field [0001] The invention relates to a heating system, in particular to a centralized lubrication pipeline heating system and a use method. Background technique [0002] In the case of low temperature, low-temperature lubricating grease can be used for the lubrication of equipment. Although low-temperature lubricating grease can guarantee its performance at extremely low temperatures, it will also become more viscous and even agglomerate due to lower temperature. Under such a low temperature condition, the resistance of the lubricating grease increases when it is transported through a long path and small-diameter lubricating pipeline, and it is very easy to be blocked, so that the components cannot be effectively lubricated. [0003] The pipelines of the centralized lubrication system are thin (generally 4mm-6mm) and long, with many branch pipelines, and the power to transport the grease is also dispersed, which is easy to block the lubrication pipeline due to the...

Problems solved by technology

[0003] The pipelines of the centralized lubrication system are thin (generally 4mm-6mm) and long, with many branch pipelines, and the power to transport the grease is also dispersed, which is easy to block the lubrication pipeline due to the viscosity of the low-temperature grease

At the same time, the space layout of the centralized lubrication pipeline is scattered, and the environment of each branch pipeline is different, so it is difficult to uniformly heat each branch pipeline at the same time, and the selection of more cold-resistant low-temperature lubricating grease will greatly increase the purchase cost of oil products
