Description

Technical Field

[0001] This utility model relates to the technical field of high-temperature resistant hydraulic motors for slag removal machines, specifically high-temperature resistant hydraulic motors for slag removal machines. Background Technology

[0002] A hydraulic motor, an actuator in a hydraulic system, converts the fluid pressure energy provided by a hydraulic pump into the mechanical energy (torque and speed) of its output shaft. Also known as an oil motor, hydraulic motors are mainly used in injection molding machinery, ships, hoists, construction machinery, mining machinery, metallurgical machinery, marine machinery, petrochemicals, and port machinery. Currently used hydraulic motors experience significant temperature increases during prolonged operation in slag removers. Without addressing this, they may malfunction and fail, impacting work efficiency. Therefore, designing a new type of high-temperature resistant hydraulic motor for slag removers is crucial. For example:

[0003] Authorization announcement number CN108119297B discloses a hydraulic motor housing and a hydraulic motor, belonging to the field of hydraulic motors. The hydraulic motor housing includes an outer housing and a stator. The outer housing has an oil port arrangement area, and the stator is provided with a radial partition. The radial partition divides the oil chamber arrangement area into a first annular arrangement area and a second annular arrangement area. An oil chamber partition is provided between the stator, the radial partition, and the outer housing to divide the first annular arrangement area into a first oil chamber, a second oil chamber, and a third oil chamber, and the second annular arrangement area into a fourth oil chamber, a fifth oil chamber, and a sixth oil chamber. Each opening communicates with an oil port through an oil chamber. Oil enters through three oil ports and exits through three oil ports, allowing the hydraulic motor to operate at full displacement. Entering oil through two oil ports reduces the displacement of the hydraulic motor. Simultaneously, the symmetrical orthographic projections of the first and fourth oil chambers, the second and sixth oil chambers, and the third and fifth oil chambers on the radial partition contribute to smoother operation of the hydraulic motor.

[0004] Based on existing solutions and actual production and processing, existing hydraulic motors have the following drawbacks, such as: it is not easy to achieve high-temperature resistance treatment for hydraulic motors, and it is difficult to avoid leakage at the connection points of hydraulic motors. Therefore, this utility model provides a high-temperature resistant hydraulic motor for slag removal machines to solve the above-mentioned problems. Utility Model Content
