Abstract
The invention discloses a kind of hydraulic quantitative distributor.Aiming to provide a kind ofly has a plurality of load when parallel connection under the discrepant operating mode, in same hydraulic system, realize rationed, the independent each other hydraulic quantitative distributor that does not have the work of influence.It comprises having two separate side by side cylinder bodies at least, in each cylinder body piston is installed, the chamber in piston left side is a left chamber, the chamber on piston right side is right chamber, and all pistons are serially connected by the connecting rod that connects two ends, the oil cylinder left and right sides, interconnect through one-way valve between each left chamber, interconnect through one-way valve between each right chamber, two oil outlets of the selector valve that left and right chamber is connected with oil pump respectively link to each other, and the left chamber of each cylinder body and right chamber are connected with two hydraulic fluid ports of corresponding two-way cylinder respectively.This invention can be carried the synchronous and geometric ratio or equidistant the moving of realizing oil cylinder under the uneven condition outside, has simple in structure, easy to manufacture, low cost, advantage safe in utilization.
Description
Technical field
The present invention relates to a kind of can be in hydraulic system can equivalent or quantitative accurate assigned unit with flow, especially in the system of heavy wool road, the oil cylinder synchronization accuracy requires high, and system pressure is not steady, can reach the hydraulic quantitative distributor of accurate balance during uncertain factors such as load load variations.
Background technique
At present, the known balanced synchronization problem of solving in hydraulic system is substantially all used equilibrium valve, relief valve, Compositional balance such as hydraulic lock and probe system, effect is undesirable, and digital equilibrium valve is arranged recently, auxiliary cylinder, computer control balance, these technical requirements height, price is expensive, debugging is also complicated, and high-precision balance sysmte is dependence on import also.The balanced synchronization problem is the most scabrous technical barrier in the hydraulic system, and especially a plurality of load are when parallel connection, and operating mode is discrepant down, is difficult to accomplish rationed in same hydraulic system, realizes the independent each other work of not having influence.
Summary of the invention
Be subjected to uncertainty to disturb synchronization accuracy low in the existing balance sysmte in order to overcome, the cost height, problem such as debugging complexity etc., providing a kind of has a plurality of load when parallel connection under the discrepant operating mode, in same hydraulic system, realize rationed, the each other independent no hydraulic quantitative distributor that influences work.
In order to achieve the above object, the technical solution adopted in the present invention is: it comprises having two separate side by side cylinder bodies at least, in each cylinder body piston is installed, the chamber in piston left side is a left chamber, the chamber on piston right side is right chamber, and all pistons are serially connected by the connecting rod that connects two ends, the oil cylinder left and right sides, interconnect through one-way valve between each left chamber, interconnect through one-way valve between each right chamber, a left side, two oil outlets of the selector valve that right chamber is connected with oil pump respectively are continuous, and the left chamber of each cylinder body and right chamber are connected with two hydraulic fluid ports of corresponding two-way cylinder respectively.
Hydraulic quantitative distributor according to the such scheme design, because all pistons in the oil cylinder are connected by the connecting rod that connects oil cylinder, piston space is realized interlock, the displacement distance that is hydraulic quantitative distributor all pistons when work is identical, when the connecting rod diameter was constant, their flow-rate ratio equaled the internal diameter ratio of their cylinder bodies.When cylinder diameter is identical, the hydraulic oil that each oil outlet was exported when piston moved is equivalent, when this hydraulic oil entered identical a plurality of two-way cylinder respectively, the distance that the piston rod of these a plurality of two-way cylinders moves was just identical, realized moving synchronously and equidistantly in the action.This hydraulic quantitative distributor can carry outside a plurality of oil cylinders to be realized under the uneven condition synchronously and geometric ratio or equidistant moving.It has simple in structure, easy to manufacture, low cost, advantage safe in utilization.
