Description

Technical Field

[0001] The present application relates to the technical field of gear oil pumps, and in particular to a gear oil pump device. Background Art

[0002] Gear oil pumps are suitable for conveying various lubricating liquids at temperatures not higher than 70°C. If high temperature of 200°C is required, high temperature resistant materials can be used. The gear oil pump is equipped with a pair of rotating gears in the pump body, one active and one passive. The gear oil pump device is required when conveying lubricating liquids by relying on the mutual engagement of the two gears.

[0003] At present, the related gear oil pump device lacks a metering and timing lubricating fluid regulating mechanism, which makes it difficult for the staff to add lubricating oil at a regular and quantitative time. It is easy for the device to not add lubricating oil for a long time, causing the gears to wear. Utility Model Content

[0007] By connecting the external oil introduction structure with the gear oil pump body, the oil is transmitted through the gear oil pump body, and the lubricating oil of the gear oil pump body is introduced into the interior of the oil bottle. When the set refueling time is reached, the metering valve opens to allow the lubricating liquid in the oil bottle to flow into the interior of the gear oil pump body. The lubricating oil added to the gear oil pump body can be metered through the metering valve. When the refueling amount set by the staff is reached, the metering valve closes to complete the metered refueling.

[0008] Preferably, both ends of the bottom of the base are fixedly connected with positioning pieces, and bolt holes are provided inside the positioning pieces.

[0010] Preferably, a threaded tube is fixedly connected to the top of the oil bottle on one side of the liquid level sensor, and a sealing cover is movably installed on the periphery of the threaded tube.

[0011] By unscrewing the sealing cap, the lubricating oil can be introduced into the interior of the oil bottle through the threaded tube, and the threaded tube can be sealed by the sealing cap.

[0012] Preferably, a support block is fixedly connected between the metering valve and the gear oil pump body, and the support block is made of stainless steel.

The lubricating oil added to the gear oil pump body can be metered through the metering valve. When the refueling amount set by the staff is reached, the metering valve closes to achieve timed and quantitative addition of lubricating oil, effectively preventing gear wear caused by drying out inside the gear oil pump body. The lubricating oil can be filtered through the oil filter cartridge to make the lubricating oil purer. BRIEF DESCRIPTION OF THE DRAWINGS
