Abstract
The utility model relates to a hydraulic and pneumatic linkage apparatus which belongs to the technical field of the mechanical equipment. The utility model is characterized in that an accumulator is communicated between a reversing valve and an oil line of an oil pump. The utility model has the advantage that for slightly reformed hydraulic or hydraulic plus vibration brick making devices and new made brick making devices, the apparatus reduces the power of an oil pump and a motor, can save energy by about 50%, raises the running speed of the oil cylinder by about one time, raises production efficiency by about one time, lowers production cost and increases enterprise profit.
Description
Technical field
The utility model belongs to mechanical equipment technical field, particularly a kind of improvement of brick equipment.
Background technique
Domestic production brick equipment enterprise all adopts hydraulic pressure or hydraulic pressure to add the vibratory process technology and makes brick equipment at present.Adopt hydraulic pressure and its advantage of vibratory process technology to be: equipment operation is steady, pressure is big.Shortcoming is that hydraulic system necessary electromotor power is very big, and the hydraulic stroke motion speed is slow, and manufacturing efficiency is low.
Summary of the invention
The purpose of this utility model is:
The hydraulic pressure of a kind of hydraulic pressure, pneumatic common driving arrangement running, pneumatic linkage are provided, the speed of device travel operation is accelerated greatly.
The technical solution of the utility model is:
Between the oil circuit of selector valve and oil pump, be linked with accumulator.
The beneficial effects of the utility model are:
Hydraulic pressure, hydraulic pressure are added the vibration brick equipment transform a little and the brick equipment of coming of new, reduce Oil pump electrical machinery power, but energy saving about 50%; Accelerate the oil cylinder motion speed, improve one times of speed approximately; Enhance productivity about one times; Reduce production costs; Increase enterprise profit.
Description of drawings
Fig. 1 is the utility model structure principle chart;
Fig. 2 is the utility model structural drawing;
Wherein: 1,2,3 is respectively oil cylinder A, B, C, and 4,5,6 is respectively selector valve A, B, C, the 7th, and pressure gauge, the 8th, accumulator, the 9th, motor, the 10th, interlock joint, the 11st, oil pump, the 12nd, relief valve, the 13rd, filter screen, the 14th, fuel tank.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Provide hydraulic oil source by oil pump, flow to selector valve,, rise or descend, advance and return action and finish production process by selector valve control hydraulic cylinder works.Selector valve oil hydraulic cylinder when meta is not worked, and the oil of oil pump output flows back to fuel tank by relief valve.
When selector valve at meta, when oil hydraulic cylinder was not worked, the oil sources that is provided by oil pump directly flowed to accumulator (gas, liquid linkage) and replenishes and store oil sources.The accumulator internal air pressure is less than 1/2nd of the oil pump working pressure.When accumulator is full of oil, when energy storage pressure was identical with pressure fuel pump, this moment, the oil of oil pump output flowed back to fuel tank by relief valve.When selector valve control oil hydraulic cylinder is worked once more, when flowing to hydraulic cylinder works, the oil sources that oil pump provides (do not have pressure this moment), the oil sources that stores in the accumulator replenishes to operating cylinder fast by air pressure, and it is fast again that the operating cylinder motion speed is added, thereby reach the advantage of enhancing productivity.
Claims (1)
1, a kind of hydraulic pressure, pneumatic linkage mainly comprise oil pump, relief valve, selector valve, oil cylinder, it is characterized in that: be linked with accumulator between the oil circuit of selector valve and oil pump.
