Abstract
The utility model discloses a kind of large-scale compressor group with negative pressure monitor and alarm system, including compressor, oil pump, fuel tank, transmitter, comparator and warning device, the fuel tank, oil pump and compressor are sequentially connected；Described transmitter one end is connected to the other end on fuel tank and connect with the comparator, and transmitter passes to comparator to the fuel tank negative pressure that will test；The signal output end of the warning device connection comparator；When compressor and/or oil pump are run, comparator is by received fuel tank negative pressure compared with setting negative pressure warning value, and when fuel tank negative pressure is lower than setting negative pressure warning value, comparator output signal is alarmed to warning device.So that operator can note abnormalities at the first time, emergency trouble shooting measures are carried out in time.It is effectively prevent unit and the motor oil inlet of large-scale compressor group, avoids lubricating oil from entering inside large-scale compressor group and causes the major accidents such as to shut down, explode, ensure safety.
Description
Technical field
The utility model belongs to oxygen generating plant technical field, and in particular to a kind of large size with negative pressure monitor and alarm system
Compressor set.
Background technique
Oxyen manutactory's production, which is protected, belongs to large-scale compression for air compressor machine, supercharger, oxygen compressor, nitrogen compressor etc. in key equipment
Machine.When unit is run or is shut down, if occurring, fuel tank negative pressure is low to cause compressor body and dragging motor oil inlet, it will serious shadow
Ring the operational safety and equipment safety of unit.Specifically, motor insulation can be made to reduce, hair when lubricating oil enters dragging motor
The raw failures such as electrical breakdown or electric leakage, seriously affect the safety in operation of motor.During compressor operation, as lubricating oil enters pressure
Contracting machine ontology gently then will affect the product quality of compressor compresses medium, the serious operational safety for influencing compressor set.And oxygen
Air compressor need to prohibit oil comprehensively, enter if any lubricating oil, can make oxygen compressor unit Fire explosion.
Utility model content
Purpose of utility model: in order to overcome the drawbacks of the prior art, the utility model provides a kind of with negative pressure monitoring
The large-scale compressor group of alarm system, the large-scale compressor group can be realized the monitoring and alarm to oil system negative pressure.
Technical solution: a kind of large-scale compressor group with negative pressure monitor and alarm system described in the utility model, including
Compressor, oil pump, fuel tank, transmitter, comparator and warning device, the fuel tank, oil pump and compressor are sequentially connected；It is described
Transmitter one end is connected to the other end on fuel tank and connect with the comparator, and transmitter is passed to the fuel tank negative pressure that will test
Comparator；The signal output end of the warning device connection comparator；When compressor and/or oil pump are run, comparator will be connect
The fuel tank negative pressure of receipts is compared with setting negative pressure warning value, when fuel tank negative pressure is lower than setting negative pressure warning value, comparator output letter
Number give warning device alarm.
Wherein, be provided with reference signal generator on the comparator, the reference signal generator be used for than
Compared with the analog signal that device exports the setting negative pressure warning value.
The utility model has the advantages that the large-scale compressor group is realized by setting transmitter, comparator and warning device to fuel tank negative pressure
Monitoring, when fuel tank negative pressure is lower than setting negative pressure warning value, warning device is sounded an alarm, so that operator can be
It notes abnormalities at the first time, carries out emergency trouble shooting measures in time, effectively prevent unit and the motor oil inlet of large-scale compressor group, keep away
Exempt from lubricating oil enter inside large-scale compressor group cause shut down, explosion etc. major accidents, ensure safety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further details with reference to the accompanying drawing.
As shown in Figure 1, present embodiment discloses a kind of large-scale compressor group with negative pressure monitor and alarm system, including pressure
Contracting machine 1, oil pump 2, fuel tank 3, transmitter 4, comparator 5, warning device 6, induced-draft fan 7, pressure gauge 8 and tee tube 9.Wherein,
Fuel tank 3, oil pump 2 and compressor 1 are sequentially connected, and the lubricating oil in fuel tank 3 is conveyed to compressor 1 to provide lubrication by oil pump 2.
In order to monitor the negative pressure of fuel tank 3, and also to easy to assembly, the present embodiment is pacified in the detection of negative pressure point of fuel tank 3
Tee tube 9 is filled, transmitter 4 and pressure gauge 8 are separately mounted to two output ends of tee tube 9.The test side of transmitter 4 passes through
The tee tube 9 is connected on fuel tank 3 to the negative pressure for detecting fuel tank 3, and the output end of transmitter 4 connects comparator 5, thus will inspection
The fuel tank negative pressure signal of survey is transferred to comparator 5.The signal output end of comparator 5 connects warning device 6, should in the present embodiment
Warning device 6 uses combined aural and visual alarm.
Specifically, be provided with reference signal generator 51 on comparator 5, the reference signal generator 51 be used for than
Compared with the analog signal that device 5 exports setting negative pressure warning value.When compressor 1 and/or oil pump 2 are run, comparator 5 is by received oil
Case negative pressure is compared with setting negative pressure warning value, and when fuel tank negative pressure is lower than setting negative pressure warning value, comparator 5 outputs signal to report
Alarm device 6 is alarmed.
Further, the induced-draft fan 7 of the large-scale compressor group is connected on fuel tank 3, when induced-draft fan 7 is run, is compared
Device 5 by received fuel tank negative pressure compared with setting negative pressure warning value, when fuel tank negative pressure lower than setting negative pressure warning value when, comparator
5 output signal to the alarm of warning device 6.
