The heat conducting oil is prepared by mixing 17.7% of alkylbenzene type, 51.8% of alkyl biphenyl, 14.5% of alkyl naphthalene and 16% of alkyl diphenyl ether. The invention is not easy to generate precipitation in the application range, has the service life longer than that of mineral oil and alkylbenzene type heat conducting oil, has the boiling point of more than 330 ℃, has good thermal stability, and is an ideal product used in the range of 300-340 ℃.
Description
Technical Field
The invention relates to the technical field of furnace water pumps, in particular to furnace water pump heat conduction oil.
Background
The boiler water circulating pump is a large-flow, low-lift single-stage centrifugal pump which is arranged in a boiler evaporation system and bears high temperature and high pressure to make working media perform forced flow, and structurally comprises a pump shell, pump blades, a bearing and a heat insulator. Boiler water circulation pumps are commonly used in start-up systems for forced circulation drum boilers and once-through boilers. A pump housing and an impeller. The pump casing is a hemispherical structure, and is characterized by that its wall thickness is small, its correspondent thermal stress is small, and the pump blade is a high-specific revolution centrifugal type, close to mixed flow type single-stage centrifugal pump, and the outlet of pump blade is equipped with pump blade to make partial kinetic energy be converted into pressure energy.
As a heat conductor of a furnace water circulation pump, it is general to use a heat transfer oil which is easy to uniformly transfer heat and adjust temperature and has less risk of fire by local heating, and it is possible to use a heat transfer oil which converts liquid (heat transfer oil) into latent heat absorbed when gas is evaporated and, conversely, latent heat emitted when gas is condensed. The heat conduction oil is good in thermal safety and oxidation stability, and is economical to use at the boiling temperature of 256-258 ℃ at normal temperature. The low melting mixture is evaporated to form vapor without any concentration of any component, and the liquid property is not changed.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
According to the embodiment of the invention, the furnace water pump heat conducting oil is provided, and the scheme is as follows:
the heat transfer oil of the present invention is manufactured in a very simple method, i.e., the heat transfer oil is made by mixing 17.7% of alkylbenzene type, 51.8% of alkyl biphenyl, 14.5% of alkyl naphthalene, and 16% of alkyl diphenyl ether. The alkylbenzene type heat conduction oil has the structure that the benzene ring is connected with the alkane branched chain, and the alkylbenzene type heat conduction oil has the advantages that the product is a product formed by combining short-chain branched chain alkane (including methyl, ethyl and isopropyl) and the benzene ring, the boiling point is 170-180 ℃, the condensation point is below-80 ℃, and the alkylbenzene type heat conduction oil can be used as an antifreeze. The side chain to which it is attached is generally methyl, dimethyl, isopropyl, etc., and the type and amount of the side chain to which it is attached determines the nature of the compound. The alkyl naphthalene with the side chain connected with a methyl group is applied to a gas phase heating system within the range of 240-280 ℃, alkyl diphenyl ether type heat conduction oil [1] is a mixture of isomers of two benzene rings with an ether group connected in the middle, two benzene rings are respectively provided with two methyl groups, the mixed heat conduction oil has low kinematic viscosity at low temperature and good fluidity, is suitable for being used in northern cold regions, recommends the use temperature not more than 330 ℃ at most, has a condensation point of-54 ℃, has a service life superior to that of mineral oil and alkyl benzene type heat conduction oil, is the most common xylene based ether type heat conduction oil at home and abroad, and is produced by manufacturers at home.
The invention is not easy to generate precipitation in the application range, has the service life longer than that of mineral oil and alkylbenzene type heat conducting oil, has the boiling point of more than 330 ℃, has good thermal stability, and is an ideal product used in the range of 300-340 ℃.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
