Description

Technical Field

[0001] This utility model relates to the field of plunger pump technology, and in particular to a plunger pump refueling device and a plunger pump. Background Technology

[0002] A piston pump is a common type of hydraulic pump that reliably provides hydraulic power, ensuring safe and efficient operation. When using a piston pump, it is necessary to replenish hydraulic oil in a timely manner with the help of a refueling device to ensure that there is always enough hydraulic oil inside the piston pump to maintain normal working pressure and flow.

[0003] Most current plunger pump refueling devices have relatively simple refueling structures, which may leave oil residue on the inner wall of the device, resulting in incomplete oil consumption and some waste of raw materials. In addition, the sealing stability of the device's sealing cap is often poor, making it prone to shaking and displacement.

[0004] Therefore, to address the issue that some oil may remain on the inner wall of the existing plunger pump refueling device, resulting in incomplete refueling, a plunger pump refueling device and plunger pump can be designed. By rotating and scraping the oil and clamping and pressing, the sealing cap can be firmly closed to seal the device. At the same time, during the refueling process, the oil adhering to the wall is continuously scraped off, ensuring that the oil inside the device is fully consumed and enhancing the practical value of the device.

[0014] Preferably, the output end of the drive motor is connected to the main body of the plunger pump, and the oil inlet pipe is connected to the interior of the main body of the plunger pump.

[0015] The beneficial effects of this utility model are:

[0016] 1. During refueling operations, oil is stored in the refueling hopper, which is then sealed with a sealing cap. The position of the arc-shaped locking block is adjusted by extending and retracting the electric telescopic rod, and the sealing cap is clamped and fixed by the arc-shaped locking block. The oil is discharged through the drain pipe.

This solves the problem that most plunger pump refueling devices may have oil residue sticking to the inner wall of the device, resulting in incomplete refueling and some waste of raw materials. In addition, the sealing stability of the device's sealing cap is often poor, thus enhancing the practical value of the device. Attached Figure Description
