The invention discloses a current stabilization valve for a pump. The current stabilization valve comprises a valve body, an oil inlet and an oil return port formed in the valve body; a current stabilization spring cavity and an output oil way connected with the oil inlet are also arranged in the valve body; a current stabilization valve element is slidingly arranged in the current stabilization spring cavity, and is provided with a piston section; the piston section is arranged between the oil return port and the oil inlet; a current stabilization valve base is connected to the valve body behind the current stabilization valve element; a return spring is arranged between the current stabilization valve element and the current stabilization valve base; a throttling port is formed in the output oil way; the output oil way behind the throttling port is connected with the current stabilizing spring cavity behind the current stabilization valve element through a connecting hole; a blind hole is formed in the back section of the current stabilization valve element; a pressure limiting valve is arranged in the blind hole; and the front section of the blind hole is connected with the oil return port through a radial hole. When the oil supply quantity of an oil pump and the load of a hydraulic system are changed, the current stabilization valve can basically keep the output flow stable to meet the requirements of stable rotating speed and steering stability of a host machine so as to guarantee normal work of the host machine.

The invention relates to the technical field of multi-group hydraulic cylinder control, and relates to a position-based multi-hydraulic cylinder coordinated control method and device for stably outputting liquid. , and then the hydraulic cylinder starts to work. By detecting the position of a group of hydraulic cylinder pistons or piston rods or plungers, it controls the reversal of another group of hydraulic cylinders to achieve orderly reversal of multiple groups of hydraulic cylinders, and the startup of the mth group of hydraulic cylinders is accelerated. The process completely overlaps with the deceleration and stop process of the m+1 group of hydraulic cylinders, and the output flow is perfectly superimposed. The invention controls the reversing valve direction of another group of hydraulic cylinders by detecting the position of the piston rod or plunger of one group of hydraulic cylinders to realize orderly reversal of multiple groups of hydraulic cylinders, stable output flow, and small flow and pressure pulsation.

The invention discloses a liquid storage tank capable of stabilizing liquid output flow. The liquid storage tank includes a main tank for storing liquid and further includes a limit device for limiting a height of a liquid level in the main tank, wherein the main tank is provided with a main tank liquid inlet for importing liquid and a main tank liquid outlet for draining liquid. The liquid storage tank capable of stabilizing liquid output flow has the advantages of stabilizing liquid levels of containers by limiting heights of the liquid levels in the containers so that the liquid output flow is stabilized, and being high in control accuracy.

The invention provides a high-pressure seawater hydraulic pump for a double-cone opposite-cone threaded rod, belonging to a volume type hydraulic pump. A core part of the high-pressure seawater hydraulic pump is a pair of cone-shaped threaded rods and a layer of bushing block with equal thickness. The two cone-shaped threaded rods with the same structure and size and the different rotating directions are symmetrically arranged at two sides of a universal coupling, and small ends of the two cone-shaped threaded rods are respectively connected with two ends of the universal coupling, so that a double-cone opposite structure is formed, and the thickness of each position on the same cross section of the bushing block is equal to one another; and a liquid passageway is formed on the cone-shaped threaded rod which is nearest to a discharge end and forms into an integrated seal chamber, and the passageway is communicated with a seal chamber and a discharge-end chamber. After the double-cone opposite structure is adopted, the whole structure of a screw pump is balanced in force application, so that the defects such as eccentric wear, leakage and the like caused by the unbalanced force application can be removed; and static pressure support is formed between the threaded rods and the bushing block, so that the threaded rod has the function of the static pressure support, therefore, the wear between the threaded rods and the bushing block can be reduced, the moving stability of the hydraulic pump can be improved, and the hydraulic pump is small in noise, long in service life, high in output pressure, stable in output flow, and small in pressure pulsation.
