Problems solved by technology

[0004] The object of the present invention is to provide a kind of oil-gas lubrication mixing equipment and its working method to solve the following technical problems: (1) the first air pump delivers air to the air valve through the first air pipe, and the second air pump sends air through the second air pipe To the parallel air valve, the air in the parallel air valve is transmitted to the two air distribution pipes respectively, and is transmitted to the air pipe three-way valve through the pneumatic coupler on the two air distribution pipes, and the air is transmitted to the air pipe three-way valve through the air pipe three-way valve. Through the main air passage, it finally enters the mixing chamber in the mixer, solving the technical problems that the lack of air pressure in the oil and gas mixing equipment in the prior art will affect the stability of the oil and gas mixing, and at the same time, the injection and transmission rate of the mixed oil and gas are insufficient; ( 2) The oil in the oil tank is extracted through the lubricating oil inlet through two oil pumps, and the lubricating oil is transferred to the limit cap through the pipe fittings. The solenoid valve opens the oil volume adjustment chamber, and the limit rod moves in the oil volume adjustment chamber. The lubricating oil is pressed into the oil inlet channel through the piston, and then the lubricating oil enters the mixing chamber. Through this setting, the limit rod of different lengths can The design controls the flow of lubricating oil. After the lubricating oil is added, the solenoid valve of the oil circuit is closed, and the sealing ring on the piston seals the oil volume adjustment cavity to prevent the lubricating oil from flowing back. By setting three equally spaced sealing rings on the piston, the oil volume The sealing effect is better when the adjustment chamber is closed, which effectively prevents lubricating oil backflow and air leakage, and solves the problem of unstable lubricating oil pressure when lubricating oil is supplied in the prior art, and at the same time, the amount of lubricating oil cannot be controlled, and the channel is sealed after the supply channel is closed If the effect is not good, it will easily cause technical problems of backflow; (3) Lubricating oil and air are mixed in the mixing chamber, and after mixing, they are blown into the mixing pressure valve, and then enter the oil and gas injection pipe through the mixing pressure valve, and adjust the mixing pressure valve to adjust the oil and gas The oil and gas throughput of the injection pipe, the mixed oil and gas enters the three-way through the oil-gas injection pipe, and then enters the two oil-gas branch pipes through the three-way respectively, observes the internal pressure of the oil-gas branch pipes through the oil-gas pressure gauge, and controls the pressure in the oil-gas branch pipes through the oil-gas control valve. The flow rate is controlled to prevent the waste caused by the excessive overflow caused by the fast speed and large flow of the mixed oil and gas. Oil and gas pass through the oil and gas inlet holes on the bearing end cover to lubricate the drive shaft, solving the problem that too much mixed oil and gas in the prior art will affect the transmission speed of the drive shaft, and at the same time, the effect of adding mixed oil and gas is not ideal, and it cannot evenly affect the drive shaft The technical problem of lubricating at the end
