Due to the technical scheme, the bus type oil mist detector has the advantages of small volume, light weight, convenient installation, simpleness and quickness, directly detects the oil mist in each cylinder of the crankcase through the oil mist sensor, and transmits oil mist concentration electric signals to the master controller through a cable; the mounting position of the cable is obviously smaller than the position of a pipeline; and the bus type oil mist detector at least can detect diesel engines with 20 cylinders, obviously enlarges a detection range, and detects each cylinder independently without interference, has the advantages of short signal transmission time and high detection accuracy, avoids a condition of false alarm or no alarm, can detect failure parts so as to maintain the failure parts directly according to display parts and save time and labor, reduces mechanism transmission wear, and prolongs the service life.
Description
Technical field
The present invention relates to a kind of diesel engine safety and protect equipment automatically, particularly a kind of oil mist detector.
Background technique
Large-scale diesel engine is as boats and ships, locomotive, the power of generator set and being widely used, in use can break down unavoidably, major failure derives from the wearing and tearing of diesel engines movement parts, oil mist concentration in part injury and the crankcase is too high, as untimely discovery reparation, will cause bigger loss, even can cause whole diesel engine to be scrapped, generally be the oil mist concentration in the crankcase to be detected now by oil mist detector, existing mist of oil sensor comprises casing, master controller, the mist of oil sensor, rotary valve, extraction pump, relief opening, master controller, the mist of oil sensor, rotary valve and extraction pump are positioned at casing.During use, mist of oil with each cylinder under the effect of extraction pump is sucked in the mist of oil sensor by rotary valve, detected the mist of oil of a cylinder, under the effect of extraction pump, the mist of oil that has detected in the mist of oil sensor is discharged, mist of oil with next cylinder sucks the mist of oil sensor again, so circulation, the mist of oil sensor again with the electrical signal transfer of the oil mist concentration of each cylinder to master controller, after the signal that master controller receives is scaled the oil mist concentration value, make comparisons with default alarming value, the value that is converted into oil mist concentration when the signal that receives is during greater than default alarming value, send instruction and give the malfunction alarm control circuit, it is reported to the police, if the value that the electrical signal that receives is converted into oil mist concentration during less than default alarming value, is then controlled sensor and continued crankcase is detected.
Existing oil mist detector has the following disadvantages:
1, when mounted, the mist of oil import of oil mist detector is to be connected on the crankcase by pipeline (as steel pipe), the mist of oil of each cylinder of crankcase is inserted in the mist of oil sensor, required mounting point is big, and is too much as crankcase, then needs the pipeline of mounting arrangements also more, because the position between the crankcase is limited, make the mounting arrangements position of pipeline limited, placed restrictions on detection range, can only detect the diesel engine of nine cylinders at most the crankcase cylinders number;
2, the mist of oil in the mist of oil sensor is difficult for draining after detecting, and each the cylinder mist of oil after the detection is mixed, and influence testing precision, generation false alarm or do not report to the police;
3, pipeline is oversize, and mist of oil enters the mist of oil sensor and needs a period of time, makes that the time of signal transmission is oversize, generally at 25 seconds;
4, the installation of pipeline connection is loaded down with trivial details, and labor intensity is big;
5, complete machine is heavier, and volume is big, and rotary valve needs driven by motor, and parts are many, the cost height, and rotary valve is difficult for processing;
6, draw mist of oil by mechanical rotation, wearing and tearing are big, and working life is short.
Summary of the invention
Purpose of the present invention just provides little, in light weight, easy for installation, the simple and direct bus type oil mist detector of a kind of volume, it is by the mist of oil of each cylinder of mist of oil sensor direct detection crankcase, give master controller with the oil mist concentration electrical signal by cable transmission, the mounting point of cable is significantly less than being positioned at of pipeline, minimum can the diesel engine of 20 cylinders the detection obviously increased detection range.
The objective of the invention is to realize by such technological scheme, it comprises master controller, mist of oil sensor, it is characterized in that: the mist of oil sensor is at least one group, and the mist of oil sensor is installed in the mist of oil acquisition port place of crankcase, and master controller is connected with the mist of oil sensor electrical by cable.
The present invention in use, the mist of oil sensor is directly installed on the mist of oil acquisition port place of crankcase, master controller can be installed on the crankcase or other position, the mist of oil sensor is given master controller with the oil mist concentration electrical signal by cable transmission, after master controller is scaled the oil mist concentration value with the signal that receives, make comparisons with default alarming value, the value that is converted into oil mist concentration when the signal that receives is during greater than default alarming value, master controller sends alarm command, if the value that the electrical signal that receives is converted into oil mist concentration is during less than default alarming value, then the main controller controls sensor continues crankcase is examined, can also on oil mist concentration sensing or main controller, connect remote supervisory equipment, realize remote monitoring.
The present invention is because the mounting point of cable is significantly less than being positioned at of pipeline, only need on each cylinder, to install respectively one group of mist of oil sensor, every group mist of oil sensor interconnects, mist of oil sensor wherein is connected with master controller by cable, the layout of cable is easy for installation, simple and direct, just can be respectively to 1-20 cylinder scope or more the diesel engine of multi-cylinder detect, obviously increased detection range, when breaking down, because each cylinder is equipped with the mist of oil sensor, can detect the position that fault takes place, directly overhaul according to the display area, the signal of the oil mist concentration of each cylinder is transferred to master controller by cable with electrical signal by the mist of oil sensor, maximum 1 second of its transmission time, obviously shortened the transmission time, save time, laborsaving, each cylinder detects separately, do not disturb mutually, improve the testing precision height, reduced rotary valve, extraction pump and motor make volume little, in light weight, reduce mechanism and rotated wearing and tearing, prolonged working life.
Owing to adopted technique scheme, it is little that the present invention has a volume, in light weight, easy for installation, simple and direct advantage, it is by the mist of oil of each cylinder of mist of oil sensor direct detection crankcase, give master controller with the oil mist concentration electrical signal by cable transmission, the mounting point of cable is significantly less than being positioned at of pipeline, minimum can the diesel engine of 20 cylinders the detection, obviously increased detection range, each cylinder detects separately, does not disturb mutually, and signal transmission time is short, improved the testing precision height, avoid the situation that false alarm takes place or do not report to the police, can detect the position that fault takes place, directly overhaul according to the display area, save time, laborsaving, reduce mechanism and rotated wearing and tearing, prolonged working life.
