Description
Technical field
The utility model belongs to the general measures field of effective operation for producing and keep machine or equipment, and particularly a kind of gas chromatograph-mass spectrometer MS safeguards and keeps equipment vacuum status system.
Background technique
Prior art is when the chromatographic MS of gas chromatography mass spectrometry safeguards, needs first to close vacuum pump emptying, make pressure in MS reach equal with external atmosphere pressure after could close MS, then carry out other operation, emptying process need 1-2 hour consuming time; When again opening MS, need first to open vacuum pump and extracted out by air in MS, just carry out the work such as sample detection after reaching vacuum state, this vacuum needs 8-9 hour consuming time.These technology increase the chromatographic maintenance cost of gas chromatography mass spectrometry, add the workload of plant maintenance, also reduce the working efficiency of equipment use personnel.
Summary of the invention
For the problems referred to above, the purpose of this utility model a kind of gas chromatograph-mass spectrometer MS will be provided to safeguard keep equipment vacuum status system, comprises the parts such as alternating current 220V power supply, circuit breaker, A.C. contactor, overheat protector, vaccum pump motor, ac contactor coil, auxiliary reclay normally opened contact, switch power, gate switch, solenoid valve, pressure switch and auxiliary reclay coil; Described gas chromatograph-mass spectrometer MS maintenance keeps equipment vacuum status system to comprise, and vacuum pressure reaches setting value, vacuum pressure safeguards three kinds of states lower than setting value and MS.
Further, described a kind of gas chromatograph-mass spectrometer MS safeguards and keeps equipment vacuum status system, it is characterized in that described vacuum pressure reaches setting value, described pressure switch disconnects automatically, the power-off while that A.C. contactor quitting work, vaccum pump motor quits work, and solenoid valve quits work, by keeping system degree of vacuum.
Further, described a kind of gas chromatograph-mass spectrometer MS safeguards and keeps equipment vacuum status system, it is characterized in that described vacuum pressure is lower than setting value, described pressure switch closes automatically, switch power rear section circuit forms loop, auxiliary reclay coil working, ac contactor coil work, vaccum pump motor works simultaneously, starts to vacuumize.
Further, described a kind of gas chromatograph-mass spectrometer MS safeguards and keeps equipment vacuum status system, when it is characterized in that described MS safeguards, described gate switch is opened, and switch power rear section circuit disconnects, and vaccum pump motor quits work, solenoid valve quits work, degree of vacuum in maintenance equipment.
Beneficial effect
:this system, carrying out, in MS maintenance process, avoiding emptying and vacuum, has been saved a large amount of time, has been alleviated the working strength of plant maintenance personnel, and improves equipment use person works efficiency.

Embodiment
The embodiment of the present invention provides a kind of gas chromatograph-mass spectrometer MS to safeguard maintenance equipment vacuum status system, comprises the parts such as alternating current 220V power supply, circuit breaker, A.C. contactor, overheat protector, vaccum pump motor, ac contactor coil, auxiliary reclay normally opened contact, switch power, gate switch, solenoid valve, pressure switch and auxiliary reclay coil; Described gas chromatograph-mass spectrometer MS maintenance keeps equipment vacuum status system to comprise, and vacuum pressure reaches setting value, vacuum pressure safeguards three kinds of states lower than setting value and MS.
Further, described a kind of gas chromatograph-mass spectrometer MS safeguards and keeps equipment vacuum status system, it is characterized in that described vacuum pressure reaches setting value, described pressure switch disconnects automatically, the power-off while that A.C. contactor quitting work, vaccum pump motor quits work, and solenoid valve quits work, by keeping system degree of vacuum.
Further, described a kind of gas chromatograph-mass spectrometer MS safeguards and keeps equipment vacuum status system, it is characterized in that described vacuum pressure is lower than setting value, described pressure switch closes automatically, switch power rear section circuit forms loop, auxiliary reclay coil working, ac contactor coil work, vaccum pump motor works simultaneously, starts to vacuumize.
Further, described a kind of gas chromatograph-mass spectrometer MS safeguards and keeps equipment vacuum status system, when it is characterized in that described MS safeguards, described gate switch is opened, and switch power rear section circuit disconnects, and vaccum pump motor quits work, solenoid valve quits work, degree of vacuum in maintenance equipment.
Below in conjunction with accompanying drawing to this practical further elaboration:
Fig. 1 shows, and now vaccum pump motor is in running order, to extract in MS air to reach vacuum state;
When vacuum pressure reaches setting, PS pressure switch disconnects automatically, the power-off while that Km quitting work, and vaccum pump motor quits work, and Y solenoid valve quits work, by keeping system degree of vacuum;
When pressure is lower than setting minimum value, PS closes automatically, and UR rear section circuit forms loop, and KA works, and Km works, and vaccum pump motor works simultaneously, starts to vacuumize;
When MS needs to safeguard, open gate switch QS, UR rear section circuit disconnects, and vaccum pump motor quits work, and Y quits work, degree of vacuum in maintenance equipment.
This system, carrying out, in MS maintenance process, avoiding emptying and vacuum, has been saved a large amount of time, has been alleviated the working strength of plant maintenance personnel, and improves equipment use person works efficiency.
