Description of the embodiments
Referring to fig. 1, a centralized lubrication pump of a wind turbine capable of monitoring the residual amount of grease in real time comprises a grease storage tank 3 and a grease driving pump 4, wherein a grease baffle plate 2 is arranged in the grease storage tank, and can block the grease to one side of the grease storage tank, as shown in the figure, the right side of the grease baffle plate is provided with a metal sheet with color indication;
the metal sheet is divided into three sections, and each section is sprayed with different colors, for example, the first section of metal sheet 5 is red, the second section of metal sheet 6 is yellow, the third section of metal sheet 7 is green, and the first section of metal sheet, the second section of metal sheet and the third section of metal sheet form an integrated metal sheet;
the red area of the first section of metal sheet shows that the grease residual amount in the grease storage tank is more than or equal to 0% and less than or equal to 10%;
the yellow area of the second section of metal sheet shows that the grease allowance in the grease storage tank is more than 10 percent and less than or equal to 30 percent;
the green area of the third section of metal sheet shows that the grease allowance in the grease storage tank is more than 30 percent and less than or equal to 50 percent;
one end of the spring 1 is fixed with the grease baffle, the other end of the spring is fixed on the side wall of the grease storage tank, and the grease baffle can slide rightwards under the action of the spring after the grease in the grease storage tank is reduced;
the bottom of the lubricating grease storage tank is fixedly provided with three proximity switches, and the proximity switches are inductive proximity switches and are divided into a first inductive proximity switch 8, a second inductive proximity switch 9 and a third inductive proximity switch 10;
working principle: the metal sheet with color indication is installed on the grease baffle in the grease storage tank, and 3 inductive proximity switches (only sensing metal) are respectively arranged at 50%, 30% and 10% of the capacity of the grease storage tank.
Working principle: when the centralized lubrication pump works, as grease is pumped out, under the pressure action of the spring, the grease baffle plate drives the metal sheet with color indication to move towards the direction of the grease driving pump, and green, yellow and red indications on the metal sheet respectively represent the sufficient, half and insufficient degree of the grease, so that the color of the exposed metal sheet and the triggering alarm of the proximity switch are conveniently observed when workers patrol equipment, and the grease allowance is referred and judged;
after the grease is used for half, the grease baffle plate moves to the proximity switch arranged at the position of 50% of the capacity of the grease storage tank with the metal sheet, after the metal sheet enters the induction range of the first inductive proximity switch, the first inductive proximity switch is connected to transmit a signal to the controller, and an alarm is sent out through the background monitoring system to remind related personnel, the alarm indication capacity corresponding to the first inductive proximity switch reaches 50%, along with pumping out of the grease, the grease baffle plate continuously moves to the proximity switch arranged at the position of 30% of the capacity of the grease storage tank with the metal sheet, at the moment, the second inductive proximity switch also senses the metal sheet, the alarm corresponding to the second inductive proximity switch and the alarm are both used for alarming, the alarm indication storage capacity of the grease reaches 30%, along with pumping out of the grease, the metal sheet continuously moves to the proximity switch arranged at the position of 10% of the capacity of the grease storage tank, the third inductive proximity switch also senses the metal sheet, at the moment, the alarm corresponding to the third inductive proximity switch and the third inductive proximity switch are used for alarming, and the alarm indication is sent out by the third inductive proximity switch, and the alarm indication is low, and the alarm indication is sent out by the staff.
The grease filling port is arranged on one side of the grease driving pump, and is pumped by a special grease filling machine through a certain pressure. In the process of filling the lubricating grease, along with the increase of the lubricating grease in the lubricating grease storage tank, the grease baffle plate can move in the opposite direction of the metal sheet, and when the third section of metal sheet leaves the induction range of the third inductive proximity switch, the alarm corresponding to the third inductive proximity switch is released. When the third section metal sheet leaves the induction range of the second inductive proximity switch, the alarm corresponding to the second inductive proximity switch is released, when the third section metal sheet leaves the induction range of the first inductive proximity switch, the alarm corresponding to the first inductive proximity switch is released, and when the green part of the metal sheet completely stretches out of the lubricating grease storage tank, the lubricating grease filling can be completed.
