Abstract
The utility model relates to a pressure control device for a double-screw air compressor. The pressure control device comprises an air intake valve, an air storage tank, an oil distributing barrel connected with the air storage tank, and a cooler connected with the oil distributing barrel and the air storage tank. The pressure control device is characterized in that two air pipes are arranged between the air intake valve and the oil distributing barrel and are respectively provided with a discharge electromagnetic valve and a loading electromagnetic valve; a pressure sensor is arranged between the air storage tank and the cooler; the pressure sensor detects pressure signals and inputs the pressure signals into an electrical box controller arranged on a box body; and the electrical box controller is respectively connected with the discharge electromagnetic valve and the loading electromagnetic valve. Hereby, the pressure control device can realize the digitalization of the loading pressure and the unloading pressure of the double-screw air compressor, and the error accuracy of the determined valve value can reach 0.5 percent, besides, the utility model also has the advantages of simple structure, convenient installation and disassembly, strong reliability, and the like.
Description
Technical field
The utility model particularly relates to a kind of good reliability, double-screw air compressor pressure control device that precision is high.
Background technique
Compressed-air actuated pressure control is particularly important in air compressor, pressure controlled whether accurate stability, Security and the gas production that directly affects the air compressor operation.General loading and the unloading of adopting pressure control switch to control compressor in the existing double-screw air compressor, the stability of the compressed air pressure in the assurance double-screw air compressor.Because pressure control switch belongs to a kind of mechanical type control switch, the pilot pressure value of manually mediating.When reconciling, pressure control switch is added the force value that operator's experience is come the set pressure control switch by artificial observation calibrated scale, owing to adopt manual tune, exists very big artificial factor, reconciles that pressure is inaccurate, deviation is big; The pressure control switch parts are more in addition, the life-span short, poor reliability, cause air compressor to exist very big potential safety hazard.
Summary of the invention
The utility model provides a kind of good reliability, double-screw air compressor pressure control device that precision is high for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of double-screw air compressor pressure control device, comprise the suction valve that is installed on the head, gas holder, the oil content bucket that links to each other with gas holder, the cooler that links to each other with the oil content bucket, cooler connects gas holder, it is characterized in that: between described suction valve and the oil content bucket two bronchuses are installed, two bronchuses are installed the vent discharge magnet valve respectively and are loaded solenoid valve, between gas holder and the cooler pressure transducer is installed, the input of pressure transducer detected pressures signal is installed in the case for electrical apparatus controller on the casing, and the case for electrical apparatus controller connects the vent discharge magnet valve respectively and loads solenoid valve.
Advantage and the good effect that the utlity model has are: owing between gas holder and cooler pressure transducer is installed, detect oil content bucket internal pressure signal by pressure transducer, the force value of measuring is directly imported the case for electrical apparatus controller, opening and closing by appliance controller controlled discharge solenoid valve and loading solenoid valve, finally the control suction valve opening and closing, finish adjustment to double-screw air compressor pressure, therefore the utility model can be realized double-screw air compressor on-load pressure and the digitizing of unloading pressure value, the accurate error precision of setup pressure value can reach 0.5% like this, and the utility model also has simple in structure in addition, easy installation and removal, advantages such as good reliability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model left view.
Among the figure: 1, oil content bucket; 2, gas holder; 3, suction valve; 4, tracheae; 5, vent discharge magnet valve; 6, load solenoid valve; 7, pressure transducer; 8, case for electrical apparatus controller; 9, cooler; 10, head.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, be installed between suction valve 3 on the head 10 and the oil content bucket 1 two bronchuses 4 are installed, vent discharge magnet valve 5 is installed respectively on two bronchuses 4 and is loaded solenoid valve 6, the cooler 9 that oil content bucket 1 connects, between gas holder 2 and the cooler 9 pressure transducer 7 is installed, the input of pressure transducer 7 detected pressures signals is installed in the case for electrical apparatus controller 8 on the casing, and case for electrical apparatus controller 8 is control connection vent discharge magnet valve 5 and loading solenoid valve 6 respectively.
Working principle: detect gas holder 2 internal pressure signals by pressure transducer 7, the force value of measuring is directly imported case for electrical apparatus controller 8, opening and closing by appliance controller controlled discharge solenoid valve 5 and loading solenoid valve 6, finish adjustment to double-screw air compressor pressure, therefore the utility model can be realized double-screw air compressor on-load pressure and the digitizing of unloading pressure value, the accurate error precision of setup pressure value can reach 0.5% like this, and the utility model also has advantages such as simple in structure, easy installation and removal, good reliability in addition.
