Abstract
The invention relates to a throttle governing hydraulic system for a sector pouring ladle. The throttle governing hydraulic system comprises a metering hydraulic pump, a one-way valve, a two-position four-way solenoid directional valve and a pilot operated compound relief valve, wherein the metering hydraulic pump and the one-way valve are connected in series; the one-way valve and the two-position four-way solenoid directional valve are connected in series; the pilot operated compound relief valve is connected between the one-way valve and the directional valve and is connected in series with a two-position two-way solenoid directional valve; two throttle valves are connected in parallel between the two-position four-way solenoid directional valve and a hydraulic cylinder, and are connected in parallel with the one-way valve. The throttle governing hydraulic system is simple in structure and high in practicability and can realize stepless speed regulation.
Description
Technical field
The present invention relates to hydraulic technique field, relate in particular to the throttle grverning hydraulic system of the fan-shaped casting ladle being applied in centrifugal casting machine.
Background technology
Force pipe centrifugal casting machine is made up of eight major parts such as machine driven system, Hydraulic Power Transmission System, PC control system, spray equipment, apparatus for pouring, cooling device, tube drawing mechanism and nozzle mechanisms.Except the running of casting mold adopts roller frictional drive, the spray of this machine is drawn advancing of dolly and casting bogie and is retreated, the tensioning of tube drawing pliers with unclamp, the transposition of spray gun and tube drawing pliers, going to work of fan-shaped casting ladle and pipe connector completes by hydraulic drive with the action such as reset.In order to ensure the productivity ratio of machine and the quality of institute's cast tube, require hydraulic system to promote spray and draw long hydraulic cylinder balance of movement in Fast Process of dolly advance and retreat accurate, nothing is impacted and is had multiple advance and retreat speed; Meet some executing agency's stepless speed regulation.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, a kind of fan-shaped casting ladle throttle grverning hydraulic system is provided, it is simple in structure, can realize stepless speed regulation, practical.
The technical solution adopted in the present invention is as follows:
Fan-shaped casting ladle throttle grverning hydraulic system, comprises quantitative hydraulic pump, check valve, two-position four-way solenoid directional control valve, pilot operated compound relief valve, and quantitative hydraulic pump is connected with check valve, and check valve is connected with a two-position four-way solenoid directional control valve; A pilot operated compound relief valve is connected between check valve and reversal valve and with a bi-bit bi-pass solenoid directional control valve connects; Two choke valves in parallel between two-position four-way solenoid directional control valve and hydraulic cylinder, choke valve is in parallel with check valve.
The invention has the advantages that: check valve can prevent that fluid from pouring in down a chimney; The direction of motion of hydraulic cylinder is by the control of bi-bit bi-pass solenoid directional control valve, the one-way throttle valve group that the two-way feed of cylinder arranges by import and export is carried out stepless high speed, has met production technology to the vert requirement of speed speed of fan-shaped casting ladle.
Accompanying drawing explanation
Fig. 1 is hydraulic schematic diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the present invention includes and comprise quantitative hydraulic pump 1, check valve 2, two-position four-way solenoid directional control valve 5, pilot operated compound relief valve 4, quantitative hydraulic pump 1 is connected with check valve 2, and check valve 2 is connected with a two-position four-way solenoid directional control valve 5; A pilot operated compound relief valve 4 is connected between check valve 2 and reversal valve 5 and with a bi-bit bi-pass solenoid directional control valve 3 connects; Two choke valves 9 in parallel and choke valve 10 between two-position four-way solenoid directional control valve 5 and hydraulic cylinder 6, choke valve 9 and choke valve 10 are in parallel with check valve 7 and check valve 8 respectively.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
