Example Embodiment

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] like figure 1 As shown, a control method for automatically judging and switching oil pump failures in a lubrication system specifically includes the following process:

[0016] Step 1. Set the low pressure switch on the oil supply main pipe, and judge whether the low pressure switch of the oil supply main pipe sends out a pressure signal and lasts for a period of time. If so, start the backup pump, and the backup pump and the main pump work together;

[0017] Preferably, the specific process of step 1 is: the pressure switch of the oil supply main pipe is set to send a signal when the pressure is low, and it is judged whether the pressure switch of the oil supply main pipe sends a low pressure signal, and the time relay starts timing, and the timing is up , the pressure switch of the oil supply main pipe still sends out a signal of low pressure, then the automa...

Abstract

The invention relates to the technical field of lubricating systems, and discloses a control method for automatic judgment and switching of an oil pump fault of a lubricating system. The control method comprises the following processes that step 1, an oil supply mother tube is provided with a low pressure switch, whether the low pressure switch of the oil supply mother tube sends a pressure signaland continues for a period of time or not is judged, if yes, a standby pump is started, and the standby pump works together with a main pump; step 2, the oil supply mother tube is further provided with a high pressure switch, whether the high pressure switch sends a pressure signal and continues for a certain period of time or not is judged, if yes, the standby pump stops working, the main pump and the lubricating system operate normally, otherwise, a step 3 is performed; and step 3, a main pump outlet is provided with a low point pressure switch, whether the pressure switch at the main pumpoutlet sends a pressure signal and continues for a period of time or not is judged, if yes, the standby pump operates as a main pump of a next construction period, and the main pump stops working andis maintained. The control method for automatic judgment and switching of the oil pump fault of the lubricating system ensures the safety of the whole system, detects a fault point in time, and improves the maintenance efficiency.

Description

technical field [0001] The invention relates to the technical field of lubricating systems, in particular to a control method for automatically judging and switching oil pump faults in a lubricating system. Background technique [0002] At present, there is a lubricating oil system with an AC oil pump for one use and one backup. During the normal use of the system, the main pump of the AC oil pump fails, and the backup AC oil pump is activated to cooperate with the main pump. As a result, the continued operation will consume a lot of power. If maintenance is required, The oil pump needs to be overhauled after shutdown, because both oil pumps are running, so it cannot be overhauled or replaced while the equipment is running. After using this control method, the above existing problems can be improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a control method for automatically judging and switching the fail...
