Abstract
The present utility model relates to a control device of the closed system with multi-functional displacement, which belongs to the pumping control device of concrete machinery. It includes a ball valve, a electrical proportion overflow valve, a electromagnetism reversal valve, an oil box and a variable orifice. Said ball valve and said electrical proportion overflow valve are in parallel connection, one end of parallel connection connects to electromagnetism reversal valve through said variable orifice, another end of parallel connection enters said oil box having two fixed orifices and a overflow valve. Electromagnetism reversal valve connects to said oil box through serial fixed orifices and said overflow valve. Said reversal valve connects orderly with the first fixed orifice, the second fixed orifice and said overflow valve, and connects with pressure oil source at the same time. Another end of the second fixed orifice connects to said electromagnetism reversal valve, and connects with the closed hydraulic oil pump connecting with pumping oil cylinder at the same time. This control device can not only control manually the pumping displacement, but control it automatically, so said control device has met the requirement of user for multiform operating mode, and has raised the pumping quality of concrete.
Description
Technical field
The utility model relates to a kind of pumping control gear of concreting machinery, the multi-functional displacement control device of particularly a kind of closed system.
Background technique
Concreting machinery is when carrying out pumping work, and its output discharge capacity need be regulated according to working condition requirement, makes the electricity consumption proportional control in the industry at present more, manually control etc., control device is single, and control procedure mostly is static control, can not adapt to multiple usage requirement.When using concreting machinery to carry out pumping work, when its output distance is far away, can not carry out long-distance remote control control; When the pumping oil cylinder commutated, moment can not be controlled automatically to discharge capacity commutating.
Summary of the invention
The purpose of this utility model is will provide a kind of not only can manually control, and the multi-functional displacement control device of the closed system that can also control automatically.
The purpose of this utility model has been achieved in that a ball valve, an electric proportional pressure control valve, a solenoid directional control valve, a fuel tank and a settable orifice, ball valve is in parallel with electric proportional pressure control valve, an end in parallel is connected with solenoid directional control valve by settable orifice, and the other end in parallel enters fuel tank; Two fixed throttle ports, a relief valve are arranged; Solenoid directional control valve enters fuel tank by the fixed throttle port and the relief valve of series connection, between fixed throttle port of connecting and relief valve, connect second fixed throttle port, connect pressure oil-source simultaneously, the other end of second fixed throttle port is connected with solenoid directional control valve, be connected with the Closed Hydraulic oil pump simultaneously, the Closed Hydraulic oil pump is connected with the pumping oil cylinder.
Beneficial effect: owing to adopt such scheme, when ball valve and settable orifice are in the complete shut-down state, when solenoid directional control valve is in off-position, pressure hydraulic oil is by fixed throttle port II, solenoid directional control valve and settable orifice, arrive electric proportional pressure control valve, change the input current of electric proportional pressure control valve, pump displacement then changes, and this process can realize control by remote control; When ball valve is in full-gear, electricity proportional pressure control valve and solenoid directional control valve outage, the opening area that changes settable orifice this moment is regulated pump displacement, when the pumping oil cylinder commutates, is in "on" position at commutation moment solenoid directional control valve, the Closed Hydraulic oil pump is because of the effect of relief valve, obtain being higher than the maximum delivery pressure of electric proportional pressure control valve, discharge capacity is increased automatically, not only can manually control in the moment of commutating, and can also control automatically, reached the purpose of this utility model.This control gear can be accomplished in several ways the control to pump displacement, and it also has dynamic control function, not only can manually control, and can also control automatically, has satisfied the usage requirement of user to various working, has improved concrete pumped mass.When concreting machinery is worked in pumping, when needs are exported discharge capacity and regulated it, can carry out long-distance remote control control; When electrical failure occurring or have signal to disturb, can also use manual control complete operation; When the pumping oil cylinder commutated, system also increased discharge capacity automatically in the moment of commutating.

Embodiment
Embodiment 1:1, ball valve; 2, electric proportional pressure control valve; 3, solenoid directional control valve; 4, fixed throttle port I; 5, pressure oil-source; 6, relief valve; 7, fuel tank; 8, pumping oil cylinder; 9, Closed Hydraulic oil pump; 10, fixed throttle port II; 11, settable orifice.
The electric proportional pressure control valve of a ball valve 1, one 2, solenoid directional control valve 3, a fuel tank 7 and a settable orifice 11 are arranged, ball valve 1 is in parallel with electric proportional pressure control valve 2, an end in parallel is connected with No. 3 ports of solenoid directional control valve 3 by settable orifice 11, and the other end in parallel enters fuel tank 7; Two fixed throttle ports are arranged, i.e. fixed throttle port I 4 and fixed throttle port II 10, a relief valve 6; No. 2 ports of solenoid directional control valve 3 enter fuel tank 7 by the fixed throttle port I 4 and the relief valve 6 of series connection, between fixed throttle port I 4 that connects and relief valve 6, connect second fixed throttle port II 10, connect pressure oil-source 5 simultaneously, the other end of second fixed throttle port II 10 is connected with No. 1 port of solenoid directional control valve 3, be connected with Closed Hydraulic oil pump 9 simultaneously, Closed Hydraulic oil pump 9 is connected with pumping oil cylinder 8.
When ball valve 1 is in the complete shut-down state, settable orifice 11 is in the complete shut-down state, pressure hydraulic oil is by fixed throttle port II 10, solenoid directional control valve 3 (this moment, electromagnet was in off-position), settable orifice 11, arrive electric proportional pressure control valve 2, as change the input current of electric proportional pressure control valve 2, pump displacement then changes, and this process can realize remote control.When ball valve 1 is in full-gear, 2 outages of electricity proportional pressure control valve, solenoid directional control valve 3 outages, then can regulate pump displacement by the opening area that changes settable orifice 11 this moment, when the pumping oil cylinder commutates, be in "on" position at commutation moment solenoid directional control valve 3, the pressure that Closed Hydraulic oil pump 9 obtains is the pressure that relief valve 6 is set up, the pressure of setting up because of relief valve 6 is higher than the maximum delivery pressure of electric proportional pressure control valve 2, so in the moment of commutating discharge capacity can be increased automatically.
