The invention provides a variable radial ultrahigh-pressure oil pump comprising a motor, a crank shaft box, a left flow distribution valve block, a right flow distribution valve block, a three-way valve and electromagnetic steering valves, wherein an oil path output end of a blade pump is connected with an input end of a filter; an output end of the filter is connected with input ends of a first electromagnetic steering valve, a second electromagnetic steering valve, a third electromagnetic steering valve and an overflowing valve; an output end of the first electromagnetic steering valve is connected with input ends of four high-pressure oil cylinders; output ends of the four high-pressure oil cylinders are connected with the output three-way valve; and the second electromagnetic steering valve is connected with the input end of one high-pressure oil cylinder. The variable radial ultrahigh-pressure oil pump has the beneficial effects that five types of ultrahigh-pressure oil pumps with different discharging amounts can be output so that the problems that pressure can not be continuously increased and supplemented in a manner of variable speed in a diamond synthesizing process can be solved, and one ultrahigh-pressure oil pump capable of reliably and stably increasing and supplementing the pressure is supplied for the synthesis of a diamond; and one six-faced ejection hydraulic machine only needs to be equipped with one variable radial ultrahigh-pressure oil pump to meet the requirements of an artificial diamond synthesis process.
Description
technical field [0001] The invention relates to the technical field of ultra-high-pressure oil supply equipment, and belongs to an ultra-high-pressure pump capable of outputting five different displacements, which is applied to ultra-high-pressure oil supply for six-sided diamond hydraulic press equipment. Background technique [0002] The six-sided top diamond press is a high-temperature and high-pressure synthesis equipment used to produce superhard materials such as artificial diamond single crystals. It needs to be equipped with different boosting rates in different stages of diamond nucleation and growth. At present, the six-sided top hydraulic press is equipped with super The high-pressure pump has a fixed output displacement. In order to meet the needs of different displacements, each six-sided hydraulic press must be equipped with 2 to 3 ultra-high pressure oil pumps of different sizes to meet the boosting requirements of the diamond synthesis process. This is the ca...
