Wrist type oscillator

Abstract

The invention belongs to the field of detection instruments and particularly relates to a wrist type oscillator. The wrist type oscillator comprises a box cover and a base, wherein the base is provided with a bracket; a rotating shaft is arranged at the top part of the bracket and is provided with a plurality of clamping devices for clamping a sample bottle; a servo motor is also fixed on the base and drives the rotating shaft by a synchronous belt wheel; the servo motor is connected with a processor by a servo driver. Compared with the common oscillator on the market, the wrist type oscillator has the advantages that due to adoption of the structure, the requirement of the inspection standard on relevant parameters is met, the digitalization and the national standardization of the sample oscillating process are realized and the labor intensity and the influences of human factors on an inspection result are greatly reduced; simultaneously, by operation on a touch screen, the rotating speed and the rotating angle in working can be simply and effectively adjusted, and data such as the rotating speed, the rotating angle and the working time can be outputted to an upper computer for further arrangement, summarization and printout.

Description

technical field [0001] The invention belongs to the field of detection instruments, and in particular relates to a wrist oscillator. Background technique [0002] The role of the fracturing proppant is to fill the artificial fractures produced by fracturing, and support the fractures after the formation pressure is released, forming oil and gas seepage channels with high conductivity. Commonly used proppants include natural quartz sand and artificial ceramsite. [0003] The ideal ceramsite proppant has uniform particles, sphericity and roundness close to 1, and has sufficient compressive strength. Proppants with different densities should be able to withstand pressures at different formation depths (52MPa, 69MPa, 86MPa, 102MPa). While ensuring high strength, the density should be as low as possible to reduce the difficulty of pumping and reduce the wear and tear of ceramsite on equipment and fracturing costs, and it cannot react with fracturing fluid and reservoir fluid at ...

Problems solved by technology

Frequency and timing are controlled by two yellow knobs with a single function

[0007]The existing wrist oscillators are all imported (Germany and the United States), and basically all are manually adjusted and controlled. They do not have digital transmission functions and are difficult to integrate with modern networking, Digital management matches
