Description

Technical Field

[0001] This utility model relates to the field of lubrication pumps, specifically a grease-lubricated gear pump with an oil tank mounted on top. Background Technology

[0002] With the development of the manufacturing industry, centralized lubrication systems are widely used for moving parts in mechanical equipment to achieve precise, periodic lubrication at set times and in measured quantities. The lubrication pump is the core component of the lubrication system and is crucial to its reliable operation.

[0003] In engineering applications, lubrication pumps often employ a bottom-mounted oil tank structure, which easily leads to long-term accumulation of grease at the bottom, resulting in waste or residual deterioration, and is prone to cavitation and unstable pressure. On the other hand, the existing lubrication pumps on the market have relatively small displacements, and there is a lack of equipment with larger flow requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a grease lubrication gear pump with an upper-mounted oil tank. It adopts an upper-mounted oil storage tank, which avoids the problems of air suction in traditional lower-mounted oil tanks and the long-term accumulation, waste, or deterioration of grease at the bottom. The use of a gear pump set provides a solution for medium-pressure, high-flow grease systems, which is conducive to its widespread use.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A grease-lubricated gear pump mounted on an oil tank includes a pump body, a motor on one side of the pump body, an oil storage tank connected to the pump body, the oil storage tank being located on the top of the pump body, a cap being provided on the top of the oil storage tank, and a gear pump assembly directly connected to the motor being installed inside the pump body.

[0010] Furthermore, the pump body is equipped with an exhaust valve, an unloading valve, and an overflow valve.

[0011] Furthermore, a mounting bracket is provided on the back of the pump body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This patent places the oil reservoir above the pump body, avoiding the problems of air suction and long-term accumulation, waste, or deterioration of grease in traditional bottom-mounted oil reservoirs.

[0020] This utility model describes a grease lubrication gear pump with an oil tank mounted on top. The main structure includes a pump body 1, a motor 6 on one side of the pump body 1, and an oil storage tank 4 connected to the pump body 1. The specific connection and sealing structure are already described in the prior art. This patent is based on the existing lubrication pump structure principle, but places the oil storage tank 4 on the top of the pump body 1 and seals it, which solves the problems of air suction in the lower oil tank and long-term accumulation, waste or deterioration of grease at the bottom. It also greatly facilitates the addition of grease.
