Problems solved by technology
Impurities and moisture will reduce the quality of refined oil and affect the accuracy of oil product calculation; accelerate the corrosion of oil storage tanks, and in severe cases will cause perforation of the bottom plate, resulting in oil leakage accidents; generate and accumulate static electricity, resulting in static electricity accidents
In addition, when the oil product is upgraded or replaced with different oil products, the remaining oil in the tank and the newly loaded oil cannot be mixed, and when the oil storage tank leaks or is damaged, it needs to be inspected or hot repaired. Oil storage tanks are cleaned, and oil storage tanks must also be cleaned and repaired regularly according to national regulations

The invention discloses a hydraulic control system of an oil storage tank cleaning robot. The hydraulic control system comprises a valve controller, a hydraulic pump station, hydraulic motors, a hydraulic oil cylinder, an adapter valve block and a hydraulic oil way pipeline. The hydraulic pump station comprises an oil tank, a motor, a variable pump, a control valve block, a filter, a pressure meter, a liquidometer, a cooler and the like. Constant displacement motors with low rotating speed and large torque are adopted as the hydraulic motors and are each provided with a speed reducer and a brake; the adapter valve block is installed at the tail of a robot, and couplings of hydraulic elements on the robot are changed to be quick couplings; the hydraulic oil way pipeline comprises hard pipes and soft pipes; all the hydraulic elements have anti-explosion, waterproof and corrosion resistant characteristics. The hydraulic control system meets the requirement for maneuverability, stability and reliability of the oil storage tank cleaning robot and achieves safety, high efficiency, energy conservation and environmental protection of oil storage tank cleaning.
Description
technical field [0001] The invention relates to the field of automatic control of an oil storage tank cleaning robot, in particular to a hydraulic control system for an oil storage tank cleaning robot. Background technique [0002] Utilizing storage tanks for storage is the main way of strategic petroleum reserves. During the long-term storage and transportation of refined oil storage tanks, a small amount of sand, soil, heavy metal salts and other impurities in the refined oil will settle and accumulate at the bottom of the storage tank together with water due to the density difference, forming a black and thick gel Substance, that is, oil storage tank bottom sludge. Impurities and moisture will reduce the quality of refined oil and affect the accuracy of oil product calculation; accelerate the corrosion of oil storage tanks, and in severe cases will cause perforation of the bottom plate, resulting in oil leakage accidents; generate and accumulate static electricity, resul...
