Low-voltage direct-current electric degasser

Abstract

The invention relates to the technical field of electric degassers, in particular to a low-voltage direct-current electric degasser. The low-voltage direct-current electric degasser comprises a support frame, a gas collecting cylinder suspension lifting frame, a gas collecting cylinder, a direct-current motor and a stirrer; the gas collecting cylinder suspension lifting frame capable of lifting is mounted on the support frame; the gas collecting cylinder is fixedly mounted at the lower end of the gas collecting cylinder suspension lifting frame; the direct-current motor is fixed at the upper end of the gas collecting cylinder; and a low-voltage direct-current power supply and a self-lifting circuit are arranged in the direct-current motor. The low-voltage direct-current electric degasser is reasonable and compact in structure and convenient in use, and uses the self-lifting circuit for converting the voltage rise of the low-voltage direct-current power supply on the degasser to a high-voltage direct-current power supply to supply needed electric energy to the motor so as to realize degassing of drilling liquid; as the low-voltage direct-current power supply is put in the direct-current motor, the influence by the operation scene environment is lower, the surface scratch damage of power supply cables due to friction is prevented, and potential safety hazards are eliminated; and the low-voltage direct-current power supply is safer compared with 380 V alternating current, so that the production safety is improved.

Description

technical field [0001] The invention relates to the technical field of electric degassers, and relates to a low-voltage DC electric degasser. Background technique [0002] The electric degasser is an important auxiliary equipment for the comprehensive mud logging instrument and the gas logging instrument; its function is to remove the natural gas, dissolved gas and free gas in the drilling fluid, and use it as the sample gas for the gas analysis of the mud logging instrument for analysis and detection. In order to judge the characteristics of oil and gas layers; the electric degasser is driven by a motor, and the motor is driven by a high-power motor because of the large resistance of the mud stirring; at present, the most commonly used is a 380V high-voltage AC motor; , When it is windy or rainy, there will be friction between the power line connected to the 380V high-voltage alternating current and the load-bearing steel wire rope, which will scratch and damage the surface...
