Description

Technical Field

[0001] This utility model relates to a novel high-temperature resistant hydraulic pump, belonging to the field of hydraulic pump technology. Background Technology

[0002] A hydraulic pump is a power component of a hydraulic system that is driven by an engine or electric motor to convert mechanical energy into hydraulic energy. It is a component that draws oil from a hydraulic tank, pressurizes it, and discharges it to the actuator. Hydraulic pumps are classified by structure into gear pumps, piston pumps, vane pumps, and screw pumps. Gear pumps are commonly small, have a simple structure, are less demanding in terms of oil cleanliness, and are relatively inexpensive. However, gear pumps have no internal protection. When the liquid requiring pressurization is a high-temperature liquid, prolonged use may damage the pump's internal structure, necessitating enhanced internal protection. Utility Model Content

The outer shell is mounted on the outer side of the base plate one, and a base plate two is located on one side of the outer shell. A front panel is located at the connection between the outer shell and the base plate one. Two heat-insulating protective plates are located on one side of the front panel. Two inner supports are located on the inner side of the base plate two. The inner supports have support grooves inside, and one end of the heat-insulating protective plate is placed inside the support groove. The heat-insulating protective plate has an inner hole inside.

[0006] In the aforementioned novel high-temperature resistant hydraulic pump, support seats are provided at the top and bottom of the front panel, and sealing rings are provided inside the support seats.

[0007] In the aforementioned novel high-temperature resistant hydraulic pump, a gear one is provided inside the outer casing, and a gear two is meshed with the bottom end of the gear one.

[0008] In the above-mentioned novel high-temperature resistant hydraulic pump, a suction chamber and a suction discharge chamber are formed on the left and right sides of the outer casing, respectively. A liquid outlet port and a liquid inlet port are provided on both sides of the outer casing, and the liquid outlet port and the liquid inlet port are respectively connected to the suction discharge chamber and the suction chamber.

[0009] In the aforementioned novel high-temperature resistant hydraulic pump, an output shaft is fitted inside the first gear and the second gear, and the output shaft passes through the sealing ring and the outer plate in sequence and is placed on the outside of the outer plate.
