Abstract
The utility model discloses a stepless working condition adjusting mechanism for inlet pressure of a CNG main station compressor, which has wider inlet pressure range and effectively guarantees that the compressor works in a best working condition. The mechanism comprises a working cylinder, a clearance cylinder connected with the working cylinder, a servo motor, a pressure sensor arranged on an air inlet pipe of the working cylinder, and a PLC, wherein the clearance cylinder comprises a cylinder body, a piston and a piston rod; the signal output end of the pressure sensor is connected with the input end of the PLC, and the output end of the PLC is connected with the servo motor that drives the piston rod to move. The pressure sensor transfers the collected inlet pressure of the working cylinder to the PLC, the PLC gives out a signal, and the piston of the clearance cylinder is driven to move in the cylinder body by the servo motor, thus automatically adjusting the opening of the clearance cylinder, and guaranteeing that the compressor operates safely with low energy consumption at the best working condition all the time.
Description
Technical field
The utility model relates to the electrodeless regulating working conditions of a kind of CNG female station compressor suction pressure mechanism.
Background technique
The female station of CNG compressor all has an optimal working point (being maximum pump discharge, best power operation point) in manufacturing and designing.Existing equipment can only manufacture and design by an operating point, departs from this operating mode in the use and following two kinds of situations will occur.When suction pressure was lower than this optimum condition, Utilization ratio reduced, the power utilization deficiency, and discharge capacity descends, the low load with strong power that promptly is commonly called as; When suction pressure was higher than this operating mode, equipment brought potential safety hazard again with overload operation.And often change owing to suction pressure in using, the situation of off-design operating point also just often takes place.
The model utility content
The technical problems to be solved in the utility model provides a kind ofly has the suction pressure scope of broad, effectively guarantee that compressor is in the electrodeless regulating working conditions of the CNG female station compressor suction pressure mechanism of optimum condition work.
For solving the problems of the technologies described above, the clearance cylinder that the utility model comprises clutch release slave cylinder and is communicated with clutch release slave cylinder, actuating motor is arranged on the pressure transducer on the clutch release slave cylinder air inlet pipeline, the PLC controller; Described clearance cylinder comprises cylinder body, piston, piston rod; The signal output part of described pressure transducer connects programmable controller PLC input end; The output terminal of PLC controller is connected with the actuating motor that drives piston rod movement.
The utility model adopts servo principle, and on the clutch release slave cylinder of the female station of CNG compressor, set up an auxiliary clearance cylinder, by pressure transducer the suction pressure of clutch release slave cylinder is delivered to the PLC controller, the PLC controller sends signal, the piston that is driven the clearance cylinder by actuating motor moves in cylinder body, thereby regulate the aperture of clearance cylinder automatically, guaranteed that compressor is all the time in optimal working point safety, low energy consumption operation.
Description of drawings
The utility model will illustrate by embodiment and with reference to the mode of accompanying drawing, wherein:
Be illustrated as the utility model embodiment's structural representation.
Embodiment
Structural representation of the present utility model as shown in the figure, the clearance cylinder 7 that comprises clutch release slave cylinder 8 and be communicated with clutch release slave cylinder, actuating motor 4 is arranged on the pressure transducer 2 on the clutch release slave cylinder air inlet pipeline 1, PLC controller 3; Described clearance cylinder comprises cylinder body, piston 6, piston rod 5; The signal output part of pressure transducer connects PLC controller input end; The output terminal of PLC controller is connected with the actuating motor that drives piston rod movement.
The utility model mechanism adopts servo principle, sets up an auxiliary clearance cylinder for CNG compressor operating cylinder, and servomechanism is realized compressor horsepower and discharge capacity control by the adjustment to clearance cylinder volume.During work, pressure transducer send the change of suction pressure information and is passed to the PLC control cabinet, sends regulating command by the PLC control cabinet according to setting program again, and actuating motor is regulated clearance cylinder volume by instruction.When suction pressure increased, servomechanism drove piston to the right motion of illustrated clearance cylinder cylinder body, transfer big clearance cylinder volume, otherwise servomechanism is turned clearance cylinder volume down, guarantees that all the time the CNG compressor is in optimal working point work.The optimum condition of compressor is not a suction pressure point just like this, but the suction pressure scope of a broad, can guarantee effectively that compressor works under optimum condition.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
