Technical Field

The invention relates to a supercharger, in particular to a supercharging system of an electro-hydraulic reversing supercharger and a control method.

Background

The hydraulic pressure booster is a device used for quickly raising the low pressure of a system to high pressure in a hydraulic system, and can be applied to a press (especially an advanced hydraulic tire vulcanizing machine), an injection molding machine and a special military approach.

in order to purchase in batches and reduce the cost, the main factories of the hydraulic tire vulcanizer mainly use a supercharger with one supercharging ratio to complete the working cycles of various models with different supercharging ratios (smaller than the supercharging ratio of the purchased supercharger).

at present, the sitting type hydraulic pressure booster on the market needs to be matched with a 6-path electromagnetic directional valve to control the opening and closing of the booster, and meanwhile, the instruction for controlling the electromagnetic directional valve is from a PLC of the whole machine. Under the concept of the system design, two supercharger design principles are mainly adopted in the market at present, wherein the first supercharger is a hydraulic balance reversing supercharger produced by miniBooster company; the second is a mechanically commutated supercharger from Parker corporation.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to the drawings, in one embodiment of the present invention, there is provided a supercharger boost system, comprising: digital signal processing module and booster pilot valve switching-over module, digital signal processing module and booster pilot valve switching-over module between the control connection, booster supercharging system send operating mode feedback signal and accuse PLC trigger signal after convert control signal input booster pilot valve switching-over module into through digital signal processing module to realize booster pilot valve switching-over. Because the working condition feedback signal participates in the working process of the whole hydraulic pressure booster in real time, the optimized control signal is matched with a mechanical structure with large internal flow area, and compared with hydraulic balance type and mechanical hydraulic pressure boosters, the reversing speed of the pilot valve core and the booster piston is greatly improved. Under the same working condition, the time required by pressurization can be shortened by more than 30 percent (the volume is more than 3L, and the volume is 3L).

A supercharger boost system control method, further comprising the steps of:

S1: the booster control algorithm program is in a stop state;

S2: when the booster control algorithm program needs the booster to work, the booster control algorithm program gives a trigger signal, calls a booster algorithm formula and continuously updates a pressure feedback signal of a load for the booster algorithm formula;

S3, setting a target pressure and an acceptable pressure drop interval value by a user;

s4: a supercharger algorithm formula in a supercharger control algorithm program is subjected to stage splitting according to a pressure feedback signal set by a user and a target pressure, the splitting stage is judged, and meanwhile, the slope of the pressure to time is adjusted according to a corresponding frequency signal output by the current stage;

S5: when the pressure signal reaches more than 85% of the target pressure, the signal frequency is increased by multiple times to ensure the switching of the pilot valve core;

S6: when the pressure signal reaches the target pressure, the booster control algorithm program enters a standby state.

S7: and when the booster control algorithm formula detects that the difference value between the pressure in the load and the target pressure is greater than the acceptable pressure drop interval value, activating a booster control algorithm program and quickly supplementing pressure.

In one specific embodiment, the booster control algorithm program is in a stop state before the complete machine system PLC program runs to the required boosting state.

when the PLC main program runs to the working beat of needing the supercharger to work, the PLC main program gives a trigger signal to call a supercharger algorithm formula, the formula continuously updates a pressure feedback signal of a load, and meanwhile, a client sets a target pressure and an acceptable pressure drop interval value according to the requirement of the client.

and the formula performs stage splitting according to the pressure feedback signal and the target pressure and a quality model empirical formula, judges that the pressure is in the current stage, and simultaneously outputs a corresponding frequency signal according to the current stage to adjust the slope of the pressure to time.

when the pressure signal reaches more than 85% of the target pressure, the signal frequency is multiplied to ensure that the piston can be in a small-amplitude oscillation stage by switching the pilot valve core, so that single output pressure fluctuation is reduced.

When the pressure signal reaches the target pressure, the PLC enters a standby state according to the working condition duration of the main program of the PLC, and when the difference between the pressure in the load and the target pressure is detected to be larger than the acceptable pressure drop interval value, the formula is activated, and the pressure is quickly supplemented according to high frequency.

Therefore, the invention has the following advantages: the reversing speed of the pilot valve core and the boosting piston is greatly improved, and the time required by boosting can be shortened by over 30 percent under the same working condition.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
