Description
Technical field
The utility model relates to a kind of hydraulic hose, the hydraulic hose of particularly a kind of integrated control circuit and the control signal that can transmission control circuit produces and have the fuel charger of this flexible pipe.
Background technique
Existing hydraulic hose, general purposes are the pipelines that liquid is carried in conduct in hydraulic system, do not possess the function of control and transmission signal.
In existing oilling machine, complete liquid transport that its hydraulic system generally is made up of critical pieces such as the control mainboard of motor, displacement pump, deaerator, flow measurement transducer, encoder, tape counter, indicating device, solenoid valve, oil sight device, oil guns and measuring system (as shown in Figure 1).In oilling machine when work,, the driven by motor displacement pump is transported to fluid eminence, delivers to high pressure, delivers to the flow measurement transducer along transport pipe the volume of oil is measured from low pressure from lower, finally comes out to consign to the user along transport pipe from nozzle.Transport pipe is as the hydraulic hose in the oiling machine hydraulic system, and its function also is the transmission pipeline as fluid.
In existing fuel charger, its hydraulic system is to work like this in quantitative refueling and two kinds of conventional oiling modes of non-quantitation oiling:
One, under the pattern of quantitative refueling: oiling person configures to refuel on the panel of control mainboard and rises number, such as 50L, mention nozzle then, this moment, motor was opened, driving displacement pump at full speed rotates, oiling person holds nozzle and goes to and wait to refuel before the vehicle, and nozzle is put into fuel tank, opens the nozzle switch and begins to refuel, this moment, encoder sent a signal to the control mainboard, the rolling counters forward of control mainboard is delivered to signal the rise number of indicating device with real-time demonstration oiling simultaneously, when volume read-out arrives 49.7L, promptly (advancement amount differs and is decided to be 0.3L as the also surplus 0.3L of volume read-out, can adjust according to actual requirements such as oil products) time, the control mainboard sends a signal, closes the main valve of solenoid valve, when counter arrives the volume read-out of setting, the control mainboard sends signal, closes the secondary valve of solenoid valve, and refueling process is finished.Deng oiling person nozzle is suspended to off switch on the oilling machine, this moment, motor and displacement pump stopped operating.
