Abstract
The invention relates to a dual-valve flow converging hydraulic control system, which comprises a movable arm hydraulic oil cylinder, a multipath reversing valve I, a hydraulic oil pump, a multipath reversing valve II, a flow sensor, a programmable logic controller (PLC) and a contactor, wherein the multipath reversing valve I is connected in parallel with the multipath reversing valve II; one end of the multipath reversing valve I and the multipath reversing valve II which are connected in parallel is connected with a hydraulic oil tank by the hydraulic oil pump, and the other end of the multipath reversing valve I and the multipath reversing valve II which are connected in parallel is connected with the movable arm hydraulic oil cylinder; the movable arm hydraulic oil cylinder, the flow sensor, the PLC and the contactor are connected with the multipath reversing valve I and the multipath reversing valve II sequentially; and the multipath reversing valve I and the multipath reversing valve II are multiway adjustable solenoid valves. In the dual-valve flow converging hydraulic control system, by introducing the two multipath reversing valves which are connected in parallel, the dual-valve flow converging control of the hydraulic movable arm hydraulic oil cylinder is realized, and the problem of insufficient oil supply in the hydraulic movable arm hydraulic oil cylinder sometimes is solved effectively.
Description
Technical field
Invention relates to a kind of hydraulic control system, especially relates to a kind of bivalve interflow hydraulic control system.
Background technique
The application of hydraulics in life and production is more and more wider.Along with development of science and technology, also more and more higher to the requirement of hydraulic control precision.Multiple directional control valve is as very important a kind of device in the hydrovalve control field, and its application area is also more and more wider.But the design discharge of existing multiple directional control valve is limited; Sometimes adopt single hydraulicdirectional control valve to control a certain hydraulic pressure swing arm hydraulic jack; The supply capability deficiency can appear; Even the situation of the oily ability of the specified mistake of selector valve occur, thereby influence the precision of hydraulic control much smaller than the oily ability of the desired mistake of swing arm hydraulic jack.
Summary of the invention
The technical problem that the present invention will solve is, overcomes the defective that existing multiple directional control valve is crossed oily scarce capacity, and a kind of bivalve interflow hydraulic control system is provided.
Technological scheme of the present invention is: a kind of bivalve interflow hydraulic control system; Comprise swing arm hydraulic jack, multiple directional control valve I, hydraulic-pressure pump; Also be provided with multiple directional control valve II, flow transducer, PLC programmable controller, contactor; Said multiple directional control valve I is parallelly connected with multiple directional control valve II; End after multiple directional control valve I and the multiple directional control valve II parallel connection links to each other with hydraulic oil container through hydraulic-pressure pump, and the other end links to each other with the swing arm hydraulic jack; Swing arm hydraulic jack, flow transducer, PLC programmable controller, contactor link to each other with multiple directional control valve I, multiple directional control valve II successively; Multiple directional control valve I and multiple directional control valve II are multidirectional adjustable electric magnet valve.
Its course of work is: when the swing arm hydraulic jack is worked; Actual needs hydraulic fluid flow rate when hydraulic system detects the work of swing arm hydraulic jack by flow sensor; And this signal passed to the PLC Programmable Logic Controller; The PLC Programmable Logic Controller is flowed through to needs by calculating according to the relevant control parameter that is stored in wherein multiple directional control valve I and multiple directional control valve II, and the flow of hydraulic oil carries out optimum distribution among multiple directional control valve I and the multiple directional control valve II; Promptly automatically this hydraulic fluid flow rate instruction is decomposed; Also promptly calculate the flow that requires multiple directional control valve I and multiple directional control valve II to pass through; And then; The PLC Programmable Logic Controller makes multiple directional control valve I and multiple directional control valve II regulate corresponding gauge tap according to command adapted thereto according to the flow control signal of having optimized by contactor; The primer fluid pressure oil pump; Hydraulic oil passes through multiple directional control valve I and multiple directional control valve II according to the flow of dispensed; And then hydraulic oil by multiple directional control valve I and the hydraulic oil by multiple directional control valve II import the swing arm hydraulic jack; Like this; Just can effectively expand the range of application of existing multiple directional control valve, solve single hydraulic multichannel conversion valve a certain specific swing arm hydraulic jack the not enough problem of supply capability occurred as the time spent.
The present invention places between swing arm hydraulic jack and the hydraulic-pressure pump through the form of two multiple directional control valves with parallel connection, has solved hydraulic pressure swing arm hydraulic jack effectively and the not enough problem of supply capability occurred.
