Description
Technical Field
The utility model belongs to the technical field of grate coolers, relates to a grate cooler, and particularly relates to a grate cooler driving lubrication oil supply device.
Background
The driving device of the grate cooler grate bed used by the driver adopts four-bar mechanisms, each four-bar mechanism is provided with 10 bearings, a single bearing corresponds to one lubrication point, 117 four-bar mechanisms are arranged on the grate bed, the number of lubrication points is 1170, and the grate bed has the characteristics of more lubrication points, long lubrication pipeline and the like; ensuring that each bearing is adequately lubricated is a key to enabling long-term, trouble-free operation of the device.
The original lubrication system adopts forced lubrication of a high-pressure pump, a pipeline part consists of two parallel oil outlet (oil return) main pipes led out (returned) by a hydraulic reversing valve (two-position four-way) in front of the high-pressure pump, an auxiliary oil supply pipe connecting a main oil pipe and an indoor distributor, the auxiliary oil supply pipe from the distributor to a lubrication point and the like, the working mode is that the oil pump is automatically started at regular time intervals (a time relay in a control box is adjusted and determined in advance), and the oil pump is pressed and conveyed into the system along one main oil supply pipe 1 through the reversing valve; the other main oil supply pipe 2 is communicated with an oil reservoir. In the oil supply process, if the main oil supply pipe 1 is firstly supplied with oil, grease pressed out by the oil pump flows through the hydraulic reversing valve and flows through the pipeline along the direction of the pipeline 1, the pressure in the pipeline is continuously increased at the moment, and when the action pressure of the distributor is reached, the distributor starts to act, and quantitative lubricating grease is sent to each lubrication point.
After all the dispensers act in sequence, about half of the lubrication points in the system obtain primary lubricating grease; after that, the pressure in the pipeline is continuously increased, when the pipeline pressure reaches the action pressure (about 8-10 MPa) adjusted by the hydraulic reversing valve in advance, a limit switch arranged on the hydraulic reversing valve is triggered, so that the motor of the oil pump stops running, and the system completes half of lubrication cycle; when the time relay starts the oil pump again, the lubricating grease flows through the hydraulic reversing valve in the pump direction and is supplied to the system through the main oil supply pipe 2, and the main pipe 1 is communicated with the oil reservoir through the hydraulic reversing valve. With the continuous rising of the pipeline pressure, the distributor acts to ensure that the other half of the lubricating points in the system obtain quantitative lubricating grease, the pressure in the main pipe 2 is continuously increased, the hydraulic reversing valve is triggered by the pressure of grease at the oil return port of the pipe 2 to stop the limit switch oil pump, all the lubricating points of the grate cooler obtain a certain amount of lubricating grease, and the system completes one-time oil supply.
The oil supply system has the following problems:
(1) The oil supply pressure is unbalanced, and the oil supply pipeline is too long, so that the oil supply pipeline is close to the oil pump and is sufficiently supplied with oil at the near part, and the oil supply is less at the far part;
(2) The pressure at the near and the far cannot be detected, and the pressure sensor is only arranged on a pump outlet hydraulic reversing valve (two sensors are arranged on an A port and a B port of the reversing valve) to monitor the pressure of the oil outlet of the whole pipeline due to the pressure loss in the pipeline in the oil supply process; the difference between the far (end pressure) and the near pressure in the oil feeding process can be 4-5 MPa (according to the rheological property of the lubricating grease, when the lubricating grease is taken as a Bingham fluid to measure the loss of the along-distance pressure and the loss of the local pressure), the near-end lubricating oil feeding is better, and the far-end oil feeding is insufficient; when the long lubrication pipeline is simultaneously supplied with oil, a far single-line bidirectional distributor cannot be opened or is opened insufficiently (the distributor is opened independently and needs 3-5 MPa pressure), the far-end oil supply effect of the system is poor, the lubrication is insufficient, the pin shafts of a far-end supporting component four-bar driving device are worn, a grate bed is sunk, the grate bed pressure is increased, the additional load is increased, the grate bed thrust is increased, the equipment damage probability is increased, and the equipment operation stability is reduced;
(3) In the oil supply process of the long-distance pipeline, the pipeline along-distance pressure loss and the local pressure loss are considered, the difference between the near-end pressure and the far-end pressure is larger, the pressure monitoring device of the original oil supply system only monitors the pump outlet pressure, the pump stops to execute the next lubrication after the corresponding pressure is reached, the pressure of the far-end pipeline in the actual use process does not reach the pressure of opening or partially opening of the distributor, the far-end oil supply is insufficient, and the problem is verified through on-site actual running condition checking.
