Embodiment 1

[0026] In order to solve the problem in the related art that the power supply voltage of the power supply in the desulfurization system is unstable and the normal operation of the oil pump cannot be guaranteed, thus causing the booster fan to trip and eventually causing the desulfurization system to stop operating, this embodiment provides a method for controlling the oil pump .

[0027] figure 1 is a flowchart of an oil pump control method according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0028] Step S102, when the power supply voltage of the power supply in the desulfurization system drops, instruct the motor of the lubricating oil pump in the desulfurization system to stop running, and the first relay is disconnected after a delay of a first time period, wherein the second relay connected in parallel with the first relay The relay opens when the supply voltage of the power supply drops and closes wh...

Embodiment 2

[0045] In this embodiment, an oil pump control device is also provided, which is used to implement the above embodiments and preferred implementation modes, and those that have already been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0046] Figure 4 is a structural block diagram of an oil pump control device according to an embodiment of the present invention, such as Figure 4 As shown, the device includes: an indication module 402, which is used to instruct the motor of the lubricating oil pump in the desulfurization system to stop running and the first relay to be disconnected after a first time delay when the power supply voltage of the power supply in the d...

Embodiment 3

[0055] Figure 5 is a structural block diagram of an oil pump control system according to an embodiment of the present invention, such as Figure 5 As shown, the system includes: a desulfurization system 502, which is used to instruct the motor of the lubricating oil pump in the desulfurization system to stop running when the power supply voltage of the power supply in the desulfurization system drops, and the first relay is disconnected after a first time delay, Wherein, the second relay connected in parallel with the first relay is disconnected when the power supply voltage of the power supply drops, and is closed when the power supply voltage of the power supply is restored; the control system 504 is connected to the above-mentioned desulfurization system 502, and when the power supply voltage of the power supply is restored In this case, the motor that controls the lubricating oil pump in the desulfurization system resumes operation, wherein the second time period between ...

Abstract

The invention provides an oil pump control method, device and system, a storage medium and an electronic device. The oil pump control method includes the steps: when the supply voltage of a power supply in a desulfurization system drops, a motor of a lubricating oil pump in the desulfurization system stops running, and a first relay is delayed for a first durationand then disconnected, wherein a second relay connected with the first relay in parallel is disconnected when the supply voltage of the power supply drops and closed when the supply voltage of the power supply is restored; and when the supply voltage of the power supply is restored, the motor of the lubricating oil pump in the desulfurization system is controlled to resume operation, wherein a second duration between dropping andrecovery of the supply voltage of the power supply is no longer than the first duration. According to the oil pump control method, device and system, the storage medium and the electronic device, theproblems that normal operation of an oil pump cannot be guaranteed and consequently the desulfurization system stops running when the supply voltage of the power supply in the desulfurization system drops in the prior art are solved, thus the desulfurization system is made to avoid voltage reduction, and the beneficial effect of ensuring the desulfurization system to continue operation when the supply voltage is restored is achieved.

Description

technical field [0001] The present invention relates to the field of electrical control, in particular to an oil pump control method and device, system, storage medium, and electronic device. Background technique [0002] When the desulfurization booster blower thin oil station oil pump motor in the related art starts to operate, since the four desulfurization flue bypass baffles operate at the same time, the required current is relatively large, and the desulfurization UPS (Uninterruptible Power System / Uninterruptible If the capacity of Power Supply (that is, uninterruptible power supply) does not meet the load demand, resulting in a decrease in output voltage, the motor contactor of the lubricating oil pump cannot be kept closed, so that the successful start of the oil pump in the desulfurization system cannot be guaranteed, that is, the oil pump stops. This will cause the tripping of the supercharger fan in the low oil pressure protection action, and finally lead to the a...
