Disclosure of Invention
In order to solve the problems, the invention provides a heating device suitable for multi-brand lubricating oil so as to improve the working efficiency and reduce the cost and save energy under the condition of avoiding the pollution of the lubricating oil.
The specific scheme of the invention is as follows:
a heating device suitable for multi-brand lubricating oil comprises a lubricating oil constant-temperature heater, a heat exchange heater, a temperature sensor, a cooler, an electric three-way valve and a heating circulation pipeline; the lubricating oil constant temperature heater is used as a central heating device, the cooled lubricating oil can be adjustably heated in real time, the hot oil is conveyed into a heating circulation pipeline, the heating circulation pipeline conveys the hot oil into each heat exchange heater, an oil-oil heat exchange mode is adopted, cold oil on the other side is heated by the heat exchange heaters, the temperature is reduced and then returns to the lubricating oil constant temperature heaters through the heating circulation pipeline, the cooled lubricating oil is reheated and enters the heating circulation pipeline after reaching the specified temperature, test oil outside the heating circulation pipeline is shunted through an electric three-way reversing valve, one part of the test oil enters the cold oil to be cooled and becomes cold oil, the other part of the test oil enters the heat exchange heaters to be heated and becomes hot oil, and the heat exchanger is in the oil-oil heat exchange mode, so that only heat exchange between the cold oil and the hot oil does not generate a blending phenomenon, oil source pollution can be avoided, the hot oil passing through the heaters and the cold oil passing through the coolers are finally mixed at an outlet to form the test oil with the test oil with the specified temperature Since the oil source temperature of the heater can be constant and the cooling medium at the cooler end can also be constant, the final mixed oil temperature can be adjusted by adjusting the opening of the electric three-way valve to adjust the proportion of the heating oil and the cooling oil.
Under the condition that the power of the heater is allowed, a plurality of sets of heat exchange heating loops can be connected in parallel on the heating circulating pipeline, so that lubricating oil with various grades or lubricating oil with various temperature requirements can be heated under the condition that only one set of heating device is provided.
Compared with the prior art, the invention has the beneficial effects that:
the invention achieves the purposes of centralized heating, lubricating oil pollution avoidance, efficiency improvement, energy conservation and emission reduction, and has the characteristics of high reliability, expandability, real-time adjustment, high efficiency, energy conservation and environmental protection.
