Abstract
The utility model discloses a kind of structure distinguishing air compressor suction valve fault; it comprises the motor (1) of air compressor, air compressor host (2), one-way exhaust valve (3) and barrel of oil and gas (4); it is characterized in that: at the upper Bonding pressure sensor (5) of barrel of oil and gas (4); pressure transducer (5) is connected with malfunction alarm limit value device (6); the alarm range of malfunction alarm limit value device (6) is 0.15MPa-0.20MPa, and it is 0.23MPa-0.28MPa that the high pressure of malfunction alarm limit value device (6) shuts down scope.The utility model realizes the stoppage protection taked unit starting overlong time by the size of detection system pressure; can effectively prevent unit in start-up course, the starting time that the fault of not closing because of suction valve causes be long and burn electric components or cause the phenomenon of power source trip.
Description
Technical field
The utility model relates to a kind of structure distinguishing air compressor suction valve fault, belongs to air compressor and manufactures field.
Background technique
Air compressor is the device mechanical energy of motor being converted to gas pressure energy, is compressed-air actuated pressure generator, is all widely used in every field.The Starting mode of general air compressor adopts star triangle start mode mostly.Suction valve is closed condition to use the air compressor of this Starting mode to require.As suction valve fault is not closed, cause unit starting under load, starting time is elongated, and inrush current meeting compared with normal situation is large.The misoperation of current air compressor controller program for preventing current detecting from causing unit in the process started, so generally take the method shielding over-current and-load detection, thus escapes inrush current.This way makes the starting time of unit long, likely causes air compressor electric components to burn, even causes power circuit breaker tripping fault.
Summary of the invention
The technical problems to be solved in the utility model is to provide one can more early judge air compressor fault, and the structure distinguishing air compressor suction valve fault that can prevent the electric element of air compressor from burning, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: the structure distinguishing air compressor suction valve fault; it comprises the motor of air compressor, air compressor host, one-way exhaust valve and barrel of oil and gas; Bonding pressure sensor in barrel of oil and gas; pressure transducer is connected with malfunction alarm limit value device; the malfunction alarm scope of malfunction alarm limit value device is 0.15MPa-0.20MPa, and it is 0.23MPa-0.28MPa that the high pressure of malfunction alarm limit value device shuts down scope.
Described malfunction alarm limit value device is single-chip microcomputer.
Compared with the prior art; the proposition of technical solutions of the utility model obtained in claimant's long campaigns air compressor PRODUCTION TRAITS process; it changes and has broken the salvo of conventional air compressor, and its effect is mainly reflected in and realizes by the size of detection system pressure the stoppage protection taked unit starting overlong time.Its principle be air compressor unit energising start time, if suction valve fault is not closed, enter main frame air quantity will compared with normal situation many, cause the system pressure compared with normal situation of unit high.Under this principle, monitoring equipment arranges malfunction alarm limit value and high pressure shutdown limit value, and pressure reaches malfunction alarm limit value group on opportunity display " suction valve fault ", and unit is not shut down; When system pressure exceedes stop value (0.23MPa ~ 0.28MPa), unit display " inside pressing through height ", " maintenance suction valve ", compressor emergency shutdown.Can effectively prevent unit in start-up course, the starting time that the fault of not closing because of suction valve causes be long and burn electric components or cause the phenomenon of power source trip.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the resolution principle figure of malfunction alarm limit value device in the utility model.
embodiment:
Embodiment: as shown in Figure 1, motor 1 is connected with air compressor host 2, air compressor host 2 is connected with one-way exhaust valve 3 and barrel of oil and gas 4, Bonding pressure sensor 5 in barrel of oil and gas 4, pressure transducer 5 is connected with malfunction alarm limit value device 6, and malfunction alarm limit value device 6 can adopt existing conventional single-chip microcomputer, and the malfunction alarm scope of malfunction alarm limit value device 6 is 0.15MPa-0.20MPa, single-chip microcomputer display " suction valve fault ", unit is not shut down; It is 0.23MPa-0.28MPa that the high pressure of malfunction alarm limit value device 6 shuts down scope, single-chip microcomputer display " inside presses through height, maintenance suction valve ", and sends halt instruction to the motor of air compressor simultaneously.
Claims (2)
1. one kind distinguishes the structure of air compressor suction valve fault; it comprises the motor (1) of air compressor, air compressor host (2), one-way exhaust valve (3) and barrel of oil and gas (4); it is characterized in that: at the upper Bonding pressure sensor (5) of barrel of oil and gas (4); pressure transducer (5) is connected with malfunction alarm limit value device (6); the malfunction alarm scope of malfunction alarm limit value device (6) is 0.15MPa-0.20MPa, and it is 0.23MPa-0.28MPa that the high pressure of malfunction alarm limit value device (6) shuts down scope.
