Parallel double overload protection multi-cavity oil pressure constant power heating system device and method

Abstract

Disclosed are a multiple-cavity oil pressure constant power heating system device with parallel connection double overload protection and a method. The device comprises an inlet main oil circuit, an outlet oil returning circuit, a control oil circuit, internal protection oil pressure even temperature heating devices and a main oil circuit emergency protecting block. The internal protection oil pressure even temperature heating devices and the main oil circuit emergency protecting block are correspondingly connected with the inlet main oil circuit and the outlet oil returning circuit in parallel. The main oil circuit emergency protecting block communicates with the control oil circuit and is connected with the outlet oil returning circuit. The even temperature heating and local protection of the system are achieved through overload control oil holes of heating section ring blocks in the internal protection oil pressure even temperature heating devices, and bypasses of all the internal protection oil pressure even temperature heating devices are formed through the main oil circuit emergency protecting block to achieve the protection of the system. the multiple-cavity oil pressure constant power heating system device with the parallel connection double overload protection has the advantages that 1, the constant power of multiple-cavity oil pressure is used to achieving heating; 2, parallel connection is adopted, so that the total heat of the system keeps invariant; and 3, local and systematical double overload protection is achieved, so that the safe operation of the system is guaranteed.

Description

Technical field [0001] The invention patent relates to a parallel double overload protection multi-cavity oil pressure constant power heating system device and method, in particular to a multi-cavity oil pressure constant power heating system device and method with parallel double overload protection. Background technique [0002] For balanced heating occasions with special requirements, such as high-precision hydraulic machine tools, high-precision instruments, gauges, flat platforms, and constant temperature protection of nuclear power reactors, traditional heating methods have the first heating and tail cooling, and the temperature distribution is uneven. At the same time, system failures are caused by oil asphalt, pipeline failures and improper connection methods, which affect the safe operation of the system. Summary of the invention [0003] The patent of the present invention provides a parallel double overload protection multi-cavity oil pressure constant power heating sys...
