The hydraulic bracket fixture is a power element in the hydraulic system during use. When the device is in operation, it will draw oil from the hydraulic oil tank. This will directly form the pressure oil discharge, and it is effectively sent to an element of the actuator. The bracket fixture is divided into a gear Bracket Fixture, a plunger bracket fixture, a vane bracket fixture and a screw bracket fixture.

The main operating mode of the hydraulic bracket fixture brings about a change in the volume of the bracket fixture chamber, so that the compressed fluid thus causes the fluid to have pressure energy, and the necessary condition is that the bracket fixture chamber has a sealed volume change.

The hydraulic bracket fixture can be divided into a variable bracket fixture and a fixed bracket fixture according to the adjustment of the flow rate. The output flow of the hydraulic bracket fixture can be adjusted according to its needs as a variable bracket fixture. The flow cannot be adjusted and is called a fixed Bracket Fixture. The volume of the gear bracket fixture is Smaller, simpler structure, less stringent requirements on the cleanliness of the oil, the price is cheaper; but the bracket fixture shaft is subject to imbalance force, serious wear and leakage.

The hydraulic bracket fixture has high volumetric efficiency and small leakage, and can work under high pressure. It is mostly used in high-power hydraulic systems, but its structure is complex, its materials and processing precision are high, the price is expensive, and the cleanliness of the oil is demanding.

When the gear bracket fixture and the vane bracket fixture in the hydraulic bracket fixture cannot meet the requirements, the piston bracket fixture is used. It is a kind of hydraulic element that supplies the pressurized liquid for the hydraulic transmission. It is a kind of bracket fixture. The cam is driven by the motor and rotates when the cam pushes the plunger. When it moves upwards, the seal volume formed by the plunger and the cylinder decreases, and the oil extrudes from the sealed volume and is discharged through the one-way valve to the desired place.
