E-type Hydraulic Lift Oiler Combination

Introduction to Hydraulic Systems

A hydraulic system is primarily composed of a hydraulic pump, oil tank, actuators, control valves, and pipelines. It operates on the principle of pressure transmission, utilizing the flow of a fluid (typically oil) to transfer force and energy within the system. In a barber chair, the role of the hydraulic system is to achieve the raising and lowering of the chair through the interaction of the oil circuit and the hydraulic pump.

Working Principle of the Hydraulic Pump

The hydraulic pump in a lift chair typically uses a manual or electric impeller pump. Within the pump, oil enters through the inlet, is drawn in by the impeller, and then, through the rotation of the impeller, the oil is compressed and discharged through the pump outlet. Simultaneously, during discharge, a negative pressure effect is created in the pump's cavity, drawing new oil from the bottom of the oil reservoir into the pump. In this way, the oil pump achieves continuous cyclic operation.

Oil Circuit System

The outlet of the oil pump is connected to the lift chair's hydraulic cylinder. The oil circuit system pushes the oil into the hydraulic cylinder to perform the lifting and lowering. The top of the oil circuit system features a hydraulic oil tank, which, in coordination with the pump, ensures a smooth supply of hydraulic fluid. From a baseline position, the pump pushes oil into the hydraulic cylinder, causing the piston to move upward, thereby driving the chair's ascent.

Construction Principle of the Hydraulic Cylinder

The hydraulic cylinder mainly consists of a piston, inclined end cover, base cover, cylinder barrel, and seals. When the pump pushes oil into the piston chamber, the piston moves upward or downward, consequently causing the chair to rise or fall. The seals are crucial for preventing oil leaks in the hydraulic cylinder. As they withstand high pressure, they are typically made from wear-resistant and pressure-resistant materials.

Overall, the operating principle of the chair lift hydraulic pump involves the hydraulic system pushing oil into the hydraulic cylinder to achieve the chair's elevation. The hydraulic cylinder, primarily constructed from the piston, inclined end cover, base cover, cylinder barrel, and seals, relies on the coordinated action of these components to enable the system's operation.
