Description
Technical field
The present invention relates to a kind of hydraulic machinery parts, be specifically related to a kind of integrated type electricity liquid corner drive unit that is used for various pipes valve driving such as butterfly valve, ball valve, control.
Background technique
Existing electrichydraulic control gyrator product is made up of hydraulic machinery parts and electric controling part two-part.The hydraulic machinery parts comprise motor, hydraulic gear pump, hydraulic jack, driving mechanism etc., and it can be exported axial torque and is connected by the control valve, the control valve switch; And controlling component is generally electric control box, be connected through tens power and signaling line with need between the hydraulic machinery parts, on control box, realizes operation of equipment, control.
The mechanical part and the controlling component of existing product separate, and have following shortcoming:
(1) connecting line is more.Often need ten numbers to be connected with signaling line with power between mechanical part and the controlling component, Installation and Debugging, Breakdown Maintenance are inconvenient, are prone to wiring error, connecting line and pull problem such as get loose;
(2) protection is relatively poor.Limit switch in the existing product, displacement transducer etc. are plug-in; And connecting line is more; Control box button, signaling lamp also expose, and often do not reach the expection requirement at the waterproof and dustproof of the comparatively abominable industrial control occasion of component environment, explosion-proof, corrosion resistance;
(3) intelligent degree is not high.Because mechanical power unit separates with controlling component, the intelligent control of part function is difficult to realization, can not realize truly integrated.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of existing technology, a kind of integrated type electricity liquid corner drive unit is provided, electric controling assembly is integrated into cleverly on the body of machinery, realize integrated control truly.
The technological scheme that the present invention adopts is: a kind of integrated type electricity liquid corner drive unit; Comprise body, electrical control tube, digital displaying window, operation knob, model selection knob, control panel and electric controling assembly, external terminal platform, angular displacement driving gear, displacement transducer, gear pump, oil pipe, actuation gear, oil cylinder and drive motor; Said gear pump by drive motor drives is connected with oil cylinder through oil pipe; Speed change gear on the oil cylinder is meshed with said actuation gear; On the prolongation axle of actuation gear the angular displacement driving gear is installed, angular displacement driving gear and said displacement transducer pass through gear engagement;
Said electrical control tube is installed on the body, and the panel of electrical control tube is provided with digital displaying window and operation knob and model selection knob, and electrical control tube inside is equipped with control panel and electric controling assembly.
Drive motor of the present invention links to each other with gear pump through coupling, motor positive and inverse driving gear pump forward, reverse pressurization; Hydraulic gear pump is connected to oil cylinder through oil pipe, can realize oil cylinder piston bar left lateral, right lateral;
The oil cylinder piston bar is connected on the actuation gear through speed change gear, output angle driving torque; The angular displacement driving gear is installed on the prolongation axle of actuation gear, and it passes through the gear interlock with displacement transducer again, realizes the measurement of angle displacement amount.
As preferably, the limit switch that position limit switch cam (open to, close to totally two) also is installed on the prolongation axle of said actuation gear and is mated can carry out the position adjustment limit switch that sets out, the output limit switch signal.
As preferably, on the said electrical control tube external terminal platform is installed, the external union that the external terminal platform is provided convenience, the user only need insert necessary power line and guide line can realize that equipment controls automatically.
Working procedure:
The user is connected to power line and necessary control line on the external terminal platform, can realize the automatic control of product.
When long-range or on-the-spot when sending out the valve signal; Signal is opened in control unit output, the motor main story, and the chamber pressurization pumps into hydraulic oil to an oil cylinder left side to drive hydraulic gear pump; Piston rod promotes to the right; Tooth bar on the piston rod and actuation gear interlock, actuation gear drive load valve realize rotating counterclockwise, and promptly open the valve process;
When long-range or on-the-spot when sending the closing valve signal; Signal is closed in control unit output, and the motor anti-pass drives hydraulic gear pump and pumps into hydraulic oil to the right cavity of cylinder pressurization; Piston rod promotes left; Tooth bar on the piston rod and actuation gear interlock, actuation gear drive load valve realize clockwise rotating, and promptly close the valve process;
On the controlling component, have out on the one hand to realizing that rotation angle is spacing, protection equipment with closing to position limit switch (triggering) by the cam on the rotatingshaft; The established angle Stroke Displacement Transducer can be calculated the aperture size on the other hand, shows at digital indicator window.
Beneficial effect of the present invention:
(1) reduces connecting line, easy to use.Original controlling component comprised with the connecting line of mechanical part at least: the three phase electric machine power line, open to position limit switch connecting line, pass to position limit switch connecting line, displacement transducer signal line.These connecting lines are because all can save;
(2) protection is high.New invention almost completely seals, and security level can reach IP65, and original product only can reach the IP54 grade;
(3) promote product technology content.Compare with traditional machinery+control box product, realize integrated control truly.
