Abstract
The utility model relates to an early warning device of an air compressor, in particular to a normal running and failure monitoring early warning device of the air compressor of a locomotive, which solves the problem that when the locomotive runs, since the air compressor is far from a cab, a driver cannot timely master the running failure information. The normal running and failure monitoring early warning device of the air compressor of the locomotive comprises a display screen, a pressure relay (YLJ), a circuit breaker (QF), a DC (direct current) contactor in a main control circuit of the air compressor, a time relay (SJ) and an alarm bell (BL), wherein a power light (LD), a green signal light (XD1), a red signal light (XD2) and a yellow signal light (XD3) are arranged on the display screen; the circuit breaker (QF) is connected with a 24V DC power line; and the power light (LD) is connected in parallel between an anode outgoing line (1) and a cathode outgoing line (2) of the circuit breaker (QF). The normal running and failure monitoring early warning device has a simple structure, is convenient to mount, has low economic cost, and can be widely applicable to all running locomotives.
Description
Technical field
The utility model relates to the air compressor prior-warning device, is specially the locomotive air compressor and runs well and the failure monitoring prior-warning device.
Background technique
Air-safety braking when locomotive and rail vehicle operation and the work of locomotive pneumatic element, its air damping source of the gas all derives from air compressor.Because locomotive air compressor not timing in the big and locomotive shunting of when operation noise is in the interrupter duty, and air compressor is far away from the operator cabin distance, when air compressor normal operation or tape jam running, the driver is difficult to grasp and find, make locomotive and train be in operation often to cause air compressor device to be damaged or inorganic oil pressure during the air compressor running, cause the tape jam running, thereby bring hidden danger to locomotive safety running; Simultaneously because locomotive is that round-the-clock running is on railway line and do not have standby host, so field maintenance is extremely inconvenient.
Summary of the invention
The utility model causes problem that driver can't in time grasp operation troubles information from operator cabin than long-range guided missile because of air compressor when solving locomotive operation, provides a kind of locomotive air compressor to run well and the failure monitoring prior-warning device.
The utility model is to adopt following technological scheme to realize: the locomotive air compressor runs well and the failure monitoring prior-warning device, comprises D.C. contactor, time relay sj and alarm bell BL in display screen, pressure relay YLJ, circuit breaker Q F, the air compressor governor circuit; Display screen is provided with power supply indicator LD, greensignal light XD1, red eye XD2 and amber lamp XD3; Circuit breaker Q F is connected with the 24V direct current supply line, is parallel with power supply indicator LD between the anodal outlet of circuit breaker Q F, the negative pole outlet; Anodal outlet links to each other with pressure relay YLJ; Be parallel with middle double-throw contact YLJ-1 and the normally-closed contact KMC1 of D.C. contactor and the series circuit that red led XD2 forms of greensignal light XD1 and pressure relay between pressure relay YLJ and the anodal outlet respectively; Pressure relay YLJ links to each other with the normally opened contact KMC2 of D.C. contactor, the coil of the normally opened contact KMC2 of D.C. contactor by time relay sj links to each other with the negative pole outlet, also is parallel with the contact of time relay sj and the series circuit that is made of the parallel branch of yellow indicator lamp XD3 and alarm bell BL between the normally opened contact KMC2 of D.C. contactor and the negative pole outlet.
Working principle of the present utility model is:
1, when circuit breaker Q F connected the 24V DC electrical source, power supply indicator LD brightened, the indication circuit on;
2, when motor and air compressor run well, when the air compressor engine oil pressure reaches specified value, the middle double-throw contact YLJ-1 action of pressure relay YLJ, green tutorial light XD1 brightens, and shows that the running of motor and air compressor, air compressor engine oil pressure reach normal value;
3, whether be subjected to the control of pneumatic element because of the needs of locomotive air pressure, during air compressor governor circuit control D.C. contactor attonity, motor stops operating, air compressor inorganic oil pressure.Double-throw contact attonity in the middle of the pressure relay YLJ, the normally-closed contact KMC1 closure of D.C. contactor, danger signal tutorial light XD2 brightens, and shows that motor and air compressor suspend, and is normal intermittence, waits for running;
4, when motor and air compressor rotates simultaneously, during air compressor inorganic oil pressure, the normally opened contact KMC2 closure of air compressor governor circuit control D.C. contactor, the time relay sj energising, after 5 seconds to 7 seconds time-delay, connect yellow signal warning lamp XD3 and alarm bell BL, implement acoustooptic alarm; The urgent prompting trainman investigation fault of stopping;
5, when air compressor device investigation fault and maintenance, cut-off breaker QF cuts off circuit and gets final product.
Described air compressor governor circuit is the technology that those skilled in the art realize easily.
The utility model signal promptly and accurately and transmission distance long, when the air compressor fault, the driver can in time understand the operation conditions of air compressor device in operator cabin, can not influence the safe operation of locomotive; Can avoid again simultaneously that the trainman not have discovery in time and causes big accident and economic loss when the air compressor device glitch, the very big economic benefit that improved.
The utility model is simple in structure, easy for installation, financial cost is low, because of air compressor causes the problem that the driver can't in time grasp operation troubles information from operator cabin than long-range guided missile, can be widely used in all operating locomotives when having solved locomotive operation.
