Description
[technical field]
This utility model relates to a kind of diesel generating set.
[background technology]
There is individual air filter the admission line foremost of diesel generating set, is responsible for required for supply engine burning
Oxygen.Air filter once blocks, and generating set carrying load ability can be made to decline, also shut down risk.Existing
In diesel generating set, for the monitoring of air filter, general by a mechanical type of assembling on air filter
Pressure indicator be monitored.Show green when back pressure is normal, when back pressure is abnormal, show redness.And for diesel oil
The air inlet of generating set the most normally lacks effective monitoring.For a long time, people are for diesel-driven generator back pressure monitoring band
The risk come, only prevents in use management.And in terms of active monitoring and early warning, not yet propose corresponding solution and do
Method.Existing diesel generating set, owing to lacking a kind of effective admission back pressure control function, is given to produce and is brought for a long time with electricity consumption
Puzzlement.
[utility model content]
Technical problem to be solved in the utility model is: make up above-mentioned the deficiencies in the prior art, proposes a kind of diesel oil and sends out
Group of motors, can effective monitoring air inlet back pressure, it is to avoid the risk of shutdown.
Technical problem of the present utility model is solved by following technical scheme:
A kind of diesel generating set, including admission line, diesel-driven generator and controller；It is characterized in that: also include
Power supply, baroceptor；Described power supply is for powering for described baroceptor；Described baroceptor is arranged on institute
Stating on admission line, described baroceptor, for detecting the gas pressure on described admission line, exports and gas pressure
The corresponding current signal of power；The input of described controller connects the outfan of described baroceptor, for receiving
Described current signal beyond set threshold range time produce warning signal.
Preferably in technical scheme,
Described baroceptor is arranged in the range of the air inlet 200～300mm of described admission line.
Described baroceptor is gas pressure detection scope baroceptor in the range of-10Kpa～0.
Described baroceptor is the current signal of output baroceptor in the range of 4～20mA.
Described controller is additionally operable to when described current signal reaches marginal value produce stopping signal, controls described diesel oil and sends out
Motor stopping.
This utility model is compared with the prior art and provides the benefit that:
Diesel generating set of the present utility model, arranges baroceptor on the admission line of diesel generating set, right
The admission pressure of admission line is monitored.Once air inlet back pressure, more than setting threshold value, just sends alarm by controller
Signal prompt operator on duty.Operator on duty can actively launch maintenance work according to warning signal or change air filter,
Or admission line back pressure abnormal without air filter back pressure by the time adjusts when arriving greatly the normal work of impact again
Maintenance, thus be effectively reduced and shut down the loss caused.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the diesel generating set of this utility model detailed description of the invention.
[detailed description of the invention]
Below in conjunction with detailed description of the invention and compare accompanying drawing this utility model is described in further details.
As it is shown in figure 1, be the structural representation of the diesel generating set of this detailed description of the invention.Diesel generating set bag
Include power supply (not shown), baroceptor 100, admission line (not shown), controller 300 and diesel oil
Electromotor 400.
Wherein, power supply is for powering for baroceptor 100.Specifically, two power supplys of baroceptor 100 are defeated
Enter end 101 and 102 and connect positive source, power cathode respectively, receive the power supply of power supply.
Baroceptor 100 is arranged on admission line, and baroceptor 100 is for detecting the gas on admission line
Pressure, exports current signal corresponding with gas pressure.Preferably, baroceptor is arranged on distance admission line
In the range of air inlet 200～300mm.On admission line, the gas pressure in this distance range is relatively big, therefore by air pressure
Sensor is arranged in this distance range, can effectively monitor the back pressure situation on admission line, and note abnormalities feelings in time
Condition.It is further preferred that the gas pressure detection scope of baroceptor is-10Kpa～0.Usually, diesel generation
Back pressure on the admission line of unit belongs to normal condition in the range of-5Kpa～0, for monitoring the back of the body less than-5Kpa
Pressing through big situation, select gas pressure detection scope at-10Kpa～the baroceptor of 0 scope, monitoring range is wide,
More comprehensive.After baroceptor detects certain gas pressure, it is converted into the output of corresponding current signal, with
For subsequent treatment.Preferably, the current signal of baroceptor output is in the range of 4～20mA, thus applicable
Reception in most controller processes.
The input of controller 300 connects the outfan of baroceptor 100, for exceeding at the current signal received
Warning signal is produced when setting threshold range.The current signal input of the reaction pressure size of baroceptor 100 output
The analog input end of controller 300, controller 300 carries out Data Management Analysis, when current signal is beyond certain threshold
During value scope, show that air pressure back pressure is excessive, produce corresponding warning signal.When producing warning signal, according to exceed
Threshold range in various degree, produces different grades of warning signal, consequently facilitating staff is by warning signal
Grade directly judges the urgency level of abnormal conditions, takes measure timely and effectively.Preferably, controller 300 is also used
In producing stopping signal when described current signal reaches marginal value, control diesel-driven generator 400 and shut down.So, may be used
When pressure is bigger, controls diesel-driven generator and shut down, in order to avoid affecting the service life of remaining operational module of diesel-driven generator.
By the cooperating of above-mentioned baroceptor and controller etc., when the entering of admission line of baroceptor detection
When atmospheric pressure arrives to a certain degree, export and surpass accordingly to the current signal of the input port of the controller of diesel generating set
Going out threshold range, thus control to produce warning signal, prompting staff adopts an effective measure, and protects Diesel engine
Group.Conventional diesel generating set, from the structure of diesel generating set, can be worked by the scheme of this detailed description of the invention
During the passive prevention that air inlet back pressure is excessive is changed into actively monitoring and early warning, thus effectively reduce the probability of shutdown,
Reduce and shut down the loss caused.
Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to
Assert that of the present utility model being embodied as is confined to these explanations.Common for this utility model art
For technical staff, make some replacements or obvious modification, Er Qiexing without departing from the concept of the premise utility
Energy or purposes are identical, all should be considered as belonging to protection domain of the present utility model.
