Thermal power plant instrument oil charging device

Abstract

The invention discloses a thermal power plant instrument oil charging device which comprises a device body. The right end in the device body is fixedly provided with an oil storage tank; the left sideof the oil storage tank is provided with a heating box, a cooling box is connected with the heating box through a first oil supply pipe, and a vacuum pump is also arranged above the heating box; theright side of the cooling box is fixedly provided with an oil charging chamber, and an oil charging head is arranged in the oil charging chamber. The thermal power plant instrument oil charging deviceis reasonable in structural design, convenient to move and high in working efficiency and can effectively remove impurities in oil and obtain more pure oil. Stable connection between a plug and an instruction oil adding port is effectively maintained, and the phenomenon of oil leakage is prevented. In addition, the oil charging amount can be more accurate through a flow meter, and resource wasteis avoided. The operability, intelligence and accuracy of the device are all greatly improved by means of a master control panel, and by arranging multiple detachable oil charging heads, the oil charging efficiency is effectively improved, and the application range of the device is also wider.

Description

technical field [0001] The invention relates to an oil flushing device, in particular to an oil flushing device for a thermal power plant instrument. Background technique [0002] Thermal power plants need to use many instruments and meters. At present, some instruments need to be flushed with oil, such as pressure gauges. The main purpose of oil-filling the pressure gauge is to reduce the buffering of the pointer to the zero position when the relative pressure changes greatly, which can effectively ensure the sensitivity of the pressure gauge. The oil filling in the pressure gauge was originally filled manually. This method has low efficiency and high labor cost. And in the manual operation, it is easy to shake between the oil pipe and the oil filling port of the instrument, thereby causing the situation of oil leakage to occur, which will pollute the outer surface of the instrument and cause the waste of instrument oil. And because the hydraulic oil will infiltrate fine ...

AI Technical Summary

Problems solved by technology

The oil filling in the pressure gauge was originally filled manually. This method is less efficient and the labor cost is high.

And in manual operation, there is easy shaking between the oil pipe and the oil filling port of the instrument, which will cause oil leakage, which will not only stain the outer surface of the instrument, but also cause a waste of instrument oil.

And because the hydraulic oil will infiltrate fine impurities such as water vapor at normal temperature, and these impurities will affect the sensitivity of the instrument to some extent, which will increase the error of the instrument virtually; the quality of today's oil-filled devices is large, the mobility is poor, and The oil flushing head is fixed, so it is inconvenient to replace or extend the length, but today’s oil filling devices cannot effectively solve these problems
