Embodiment 1

[0060] Such as figure 1 As shown, this embodiment provides a plate-and-frame oil filter unit, including a main filter plate module 1 and a spare filter plate module, the oil inlet end of the main filter plate module 1 and the main oil inlet pipe of the plate-and-frame oil filter unit 13, the oil outlet is connected to the main oil outlet pipeline 14, the oil flows into the main filter plate module 1 from the main oil inlet pipeline 13, and flows out from the main oil outlet pipeline 14 after being filtered by the main filter plate module 1, completing the oil filtration The spare filter plate module is connected between the main oil inlet pipeline 13 and the main oil outlet pipeline 14, and is arranged in parallel with the main filter plate module 1, when the main filter plate module 1 cannot be used normally, it is guaranteed that the oil can be fed by the main oil inlet The oil pipe 13 flows into the spare filter plate module. The spare filter plate module setting can effec...

Embodiment 2

[0085] The difference between this embodiment and the first embodiment above is that the differential pressure sensing module includes a fourth differential pressure sensor 7 for detecting the differential pressure between the main oil inlet pipeline 13 and the main oil outlet pipeline 14, which can be more intuitive Reflect the overall operation of the plate and frame oil filter unit.

[0086] Such as figure 2 As shown, in this embodiment, the first backup control valve is the first differential pressure valve 10, and when the pressure differential across the main filter plate module 1 reaches the set differential pressure, the first differential pressure valve 10 will automatically open; the second backup control valve is the second differential pressure valve 11, and when the differential pressure of the first backup filter plate module 2 reaches the set differential pressure, the second differential pressure valve 11 is automatically opened. This method of automatically ...

Embodiment 3

[0094] Such as Figure 5 , Figure 6 As shown, this embodiment provides a control method for the plate-and-frame oil filter unit in the above-mentioned embodiments, and controls switching of the main filter plate module 1 and / or Or the working status of the spare filter plate module.

[0095] Such as Figure 5 As shown, when the plate and frame oil filter is running, the first differential pressure sensor 4 detects the differential pressure at both ends of the main filter plate module 1 in real time. When the main filter plate module 1 works normally, the pressure detected by the first differential pressure sensor 4 The difference is small. After running for a period of time, the filter paper of the main filter plate module 1 will be clogged, and the pressure difference between the two ends of the main filter plate module 1 will gradually increase. When it is judged that the pressure detected by the first differential pressure sensor 4 When the pressure difference is greate...

Abstract

The invention discloses a plate-and-frame oil filter and a control method thereof, the plate-and-frame oil filter comprises: a main filter plate module, wherein the oil inlet end of which is connected with a main oil inlet pipeline, and the oil outlet end of which is connected with a main oil outlet pipeline; a standby filter plate module connected between the main oil inlet pipeline and the main oil outlet pipeline, wherein the standby filter plate module and the main filter plate module are arranged in parallel; a pressure difference sensing module used for detecting pressure difference information between the two ends of the main filter plate module and / or the two ends of the standby filter plate module and / or between the main oil inlet pipeline and the main oil outlet pipeline; and a control module used for judging whether the main filter plate module and / or the standby filter plate module are / is abnormal or not according to the pressure difference information detected by the pressure difference sensing module. According to the oil filter, the working state of the main filter plate module and / or the standby filter plate module can be controlled to be switched according to the pressure difference information detected by the pressure difference sensing module, when the main filter plate module is blocked, the standby filter plate module is controlled to be started, normal operation of the oil filter is guaranteed, and meanwhile the phenomena of oil leakage and oil overflowing of the oil filter due to too high pressure difference are effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of oil filters, and in particular relates to a plate-and-frame type oil filter and a control method thereof. Background technique [0002] Plate and frame oil filter is a kind of mechanical equipment that filters solid impurities and moisture in oil and improves oil quality. It is widely used in power plants, power stations, industrial and mining enterprises, lubricating oil warehouses, tractor stations, petroleum, chemical industry, metallurgy, national defense It is mainly used to filter transformer oil, turbine oil, engine oil, diesel oil, aviation hydraulic oil, etc. It can also use stainless steel to filter vegetable oil. The plate and frame oil filter has simple structure and easy operation. Convenience, low operating cost, etc., but it is prone to oil leakage and leakage during use, and the filter paper is prone to clogging after a certain period of use, resulting in excessive pressure difference, and...
