Description

Technical Field

[0001] The present invention relates to the technical field of oil level detection, and more particularly to a lubricating oil level detection device. Background Art

[0002] The lubricating oil enters the oil level detector through the oil pipe, generating an upward thrust on the valve core, causing the valve core to move upward. When the oil supply reaches a stable value, the valve core moves to the highest point. When the proximity switch detects the screw, the system detects that the lubricating oil circuit is working normally. The excess lubricating oil flows out from the gap between the valve core and the fixed block and the oil drain port at the bottom of the fixed block, and the equipment can operate normally.

[0003] When the physical properties of the equipment's lubricating oil (such as viscosity) change, or the oil level in the tank is too low, the oil pump's oil supply is interrupted, and the flow of lubricating oil into the fixed block cavity decreases, preventing the valve core from being pushed up to its highest point in time. Although the lubricating oil can still lubricate normally, the oil level detection system requires the sensor to respond within a specified time, i.e., 35 seconds. Otherwise, the system will indicate insufficient oil level and the equipment will not operate normally. When the machine is shut down for approximately 40 seconds (40 seconds is an internal parameter of the machine), without an independent motor driving the oil pump, the test requires the valve core to drop to its startup state. If the sensor still senses, the message "Oil Level Energy Efficiency Test Failed" will be displayed. The oil level detection time is a fixed parameter setting of the equipment program and cannot be changed. The lubricating oil test must be completed within this specified time, and the oil level test cannot be controlled by adjusting the detection time. During the production process, the physical properties of the lubricating oil may change, and the aforementioned detection time may not match. Even if the lubricating oil is newly replaced, the detector valve core may not be pushed into place within the specified time and may not be disconnected from the proximity switch within the specified time after shutdown. When such phenomena occur, the system detects that the oil supply is abnormal, which is a false detection and the machine cannot be started, seriously affecting the equipment's operating efficiency.

[0004] In summary, how to improve the operating efficiency of equipment is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, an object of the present invention is to provide a lubricating oil level detection device, which is used to solve the technical problems existing in the above-mentioned background technology.

An adjusting screw is provided at the bottom of the fixed block, and the length of the adjusting screw extending into the oil storage chamber is controllable. By changing the length of the adjusting screw extending into the oil storage chamber, the amount of lubricating oil that can be stored in the oil storage chamber can be changed. When the lubricating oil between the fixed block and the valve core reaches a certain amount, the valve core rises, and the protruding device on the valve core rises accordingly. By controlling the adjusting screw to move downward, the lubricating oil flow area is reduced, the oil unloading amount is reduced, and the valve core is continuously in a high point position to avoid false detection. By controlling the adjusting screw to move upward, the lubricating oil flow area is increased, the time for the control valve core to disengage from the proximity switch induction is reduced, and the induction time required for disengagement from the proximity switch within a certain period of time during shutdown is matched. Through the above operation, unnecessary shutdowns caused by false detection of the oil level detector can be eliminated, thereby achieving the purpose of improving equipment operation efficiency.
