Abstract
The invention relates to the field of engineering machines, in particular to an air filter system for engineering machines. The air filter system comprises a diesel engine and an air filter which are connected through an air pipe. The system is characterized in that the air pipe is connected with a tee joint, main pipes of the tee joint are connected with the diesel engine and the air filter respectively, a branch pipe of the tee joint is connected with a pressure sensor which is in circuit connection with a PLC control system, and the PLC control system is in circuit connection with an alarm. Pressure is generated when air flows in the air pipe, when a filter element is blocked, pressure of air in the air pipe is reduced, at the moment, the pressure sensor receives a signal and transmits the signal to the alarm, the alarm gives an alarm to remind a driver to replace the filter element, the driver can replace the filter element in time, and the filter effect of the air filter can be fully guaranteed.
Description
(1) technical field
The present invention relates to engineering machinery field, particularly a kind of engineering machinery air filtering system.
(2) background technique
Air-strainer is the device of the granulometric impurity removed in air.During reciprocating machine (internal-combustion engine, reciprocating compressor etc.) work, contain the impurity such as dust just by the wearing and tearing of aggravation part if sucked in air, so air-strainer must be equipped with.Air-strainer comprises filter core and housing two-part, has grown filter core service time and also can produce blocking, change and will affect entering of air not in time, morning of replacing and can cause waste.
(3) summary of the invention
The present invention, in order to make up the defect of prior art, provides the engineering machinery air filtering system on a kind of accurate assurance filter element replacing opportunity.
The present invention is achieved through the following technical solutions:
A kind of engineering machinery air filtering system, comprise the diesel engine and air-strainer that are connected by tracheae, it is characterized in that: connecting tee on described tracheae, the supervisor of described threeway connects diesel engine and air-strainer respectively, the arm Bonding pressure sensor of described threeway, described pressure transducer is connected with PLC control system circuit, and described PLC control system circuit connects alarm.
The invention has the beneficial effects as follows:
Air can produce pressure in tracheal strips flow process, when filter core blocks, tracheal strips air pressure reduces, at this moment pressure transducer is received signal and is passed to alarm, alarm equipment alarm, remind driver this renew cartridge, such driver just can more renew cartridge in time, fully can ensure the filtering effect of air-strainer.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is main TV structure schematic diagram of the present invention.
In figure, 1 diesel engine, 2 air-strainer, 3 tracheaes, 4 threeways, 5PLC control system, 6 pressure transducers, 7 alarms.
(5) embodiment
Accompanying drawing is specific embodiments of the invention.As shown in Figure 1, this kind of engineering machinery air filtering system, comprise the diesel engine 1 and air-strainer 2 that are connected by tracheae 3, connecting tee 4 on tracheae 3, the supervisor of threeway 4 connects diesel engine 1 and air-strainer 3 respectively, the arm Bonding pressure sensor 6 of threeway 4, pressure transducer 6 is connected with PLC control system 5 circuit, and PLC control system 5 circuit connects alarm 7.
Whole system is controlled by PLC control system 5, the force value that prior setting alarm 7 is reported to the police, when there is blocking in filter core, tracheae 3 inner air pressure reduces, the force value now experienced is passed to PLC control system 5 by pressure transducer 6, if PLC control system 5 judges that air pressure reaches alert levels, then by signal transmission to alarm 7, alarm 7 is reported to the police, and reminds the timely more renew cartridge of driver.
Except technical characteristics described in specification, all the other technical characteristicss are those skilled in the art's known technology.
Claims (1)
1. an engineering machinery air filtering system, comprise the diesel engine (1) and air-strainer (2) that are connected by tracheae (3), it is characterized in that: the upper connecting tee (4) of described tracheae (3), the supervisor of described threeway (4) connects diesel engine (1) and air-strainer (2) respectively, the arm Bonding pressure sensor (6) of described threeway (4), described pressure transducer (6) is connected with PLC control system (5) circuit, and described PLC control system (5) circuit connects alarm (7).
