Abstract

The invention relates to a hydraulic oil circulation cooling system of a drilling machine. The hydraulic oil circulation cooling system of the drilling machine is characterized by comprising an oil returning pipe device; the oil returning pipe device comprises a square pipe and a seamless steel pipe arranged on the inner side of the square pipe; an inner hole of the seamless steel pipe is a hydraulic oil channel; a slurry channel is formed between the seamless steel pipe and the square pipe; one end of the square pipe is connected with a slurry pump through a slurry pipeline; an outlet in the other end of the square pipe is connected with a water flow channel; one end of the hydraulic oil channel is connected with an oil tank through an oil pipe; the other end of the hydraulic oil channel is connected with an oil outlet of an oil radiator device through an oil pipe; and an oil inlet of the oil radiator device is connected with an oil storage tank. A drainage plug is arranged on the lower portion of the square pipe. The oil radiator device is a wind radiator and comprises a gear motor, blowing fan blades and a radiator. Water supplied by the slurry pump is effectively utilized to flow into the oil returning pipe, high-temperature oil inside the oil returning pipe is cooled along with water flow, and on the premise of not increasing the cost, the oil cooling efficiency is greatly improved.

Description

technical field [0001] The invention relates to a drilling rig hydraulic oil circulation cooling system, which belongs to the technical field of hydraulic systems. Background technique [0002] With the continuous development and progress of social science and technology, the construction machinery industry is also growing rapidly, and the hydraulic system is also widely used with the continuous updating of construction machinery and equipment. The hydraulic system is undoubtedly the core part of the whole equipment. During the operation of the hydraulic system, due to mechanical loss and volume loss, it will cause the system to heat up. The heat generated by the system will increase the temperature of the oil, and the high oil temperature will make the hydraulic power components And the performance of the executive components is reduced, and serious components can be damaged. High-temperature cooling of oil has always been a problem that has been concerned and must be solv...
