During the prosperous development of industrial machinery, the hydraulic technology is widely used in comparison with the traditional electric drive. The application of hydraulic pump stations that provide hydraulic power for hydraulic equipment is widely recognized.
The working principle of the common hydraulic station: the motor drives the oil pump to rotate, the pump lifts the oil from the oil pump, and the mechanical energy is converted into the pressure energy of the hydraulic oil. The hydraulic oil realizes the direction, pressure and flow through the integrated block (or valve combination) hydraulic valve. After adjustment, it is transmitted to the cylinder or oil motor of the hydraulic machine through the external pipeline, thus controlling the change of the direction of the liquid engine, the magnitude of the force and the speed of the speed, and promoting the work of various hydraulic machines. Hydraulic pump station design Through the analysis of the specific working conditions of the hydraulic pump station, the design of the overall scheme of the hydraulic pump station is determined, and the hydraulic system of the hydraulic pump station is designed. Through the detailed design of the hydraulic pump station, it meets the requirements of the user, while providing hydraulic power to hydraulic equipment of different pressures and flows.
The whole set of hydraulic pump station generally includes: pure copper wire motor; medium and high pressure oil pipe; multi-channel hydraulic valve controller; high pressure oil standard; oil return pipe; water cooling pipe; fan heat controller; hydraulic column; Main station housing of pump station; hydraulic pump station identification plate; fixing bolt; hydraulic cylinder block; total electric control module; other hydraulic accessory components; hydraulic station wire; hydraulic system (some special industries can add protective cover device)
Hydraulic pumping station application range: forging machinery, injection molding machines, machine tools, processing enterprises, robots, mining machinery, packaging machinery, walking machinery, engineering machinery, construction machinery, agricultural machinery, automobiles, airplanes, spacecraft, satellite launching, etc. , ship, ship, ship deck machinery, operation and control system, marine engineering, marine development platform, subsea drilling, underwater operation hydraulic pumping station
The hydraulic pump is a power component of the hydraulic system, and is driven by an engine or an electric motor to suck oil from the hydraulic oil tank to form a component that is discharged to the actuator. The hydraulic pump is divided into a gear pump, a plunger pump, a vane pump and a screw pump according to the structure.
A hydraulic component that provides pressurized liquid to a hydraulic drive and is a type of pump. Its function is to convert the mechanical energy of a power machine (such as an electric motor and an internal combustion engine) into the pressure energy of a liquid. There are many factors affecting the service life of the hydraulic pump. In addition to the design and manufacturing factors of the pump itself, it is also related to the selection of components related to the pump (such as couplings, oil filters, etc.) and the operation during the test run. The working principle of the hydraulic pump is that the movement brings about a change in the volume of the pump chamber, so that the fluid is compressed to make the fluid have pressure energy. A certain condition is that the pump chamber has a sealed volume change.
Types of commonly used hydraulic pumps:
1. According to whether the flow can be adjusted, it can be divided into: variable pump and fixed pump. The output flow can be adjusted as needed, called the variable pump, and the flow cannot be adjusted, called the fixed pump.
2 , according to the pump structure commonly used in hydraulic systems are divided into three types: gear pump, vane pump and plunger pump .
Gear pump: small volume, simple structure, less cleanliness of oil, cheaper cost; but the pump shaft is unbalanced, wear is serious, and leakage is large.
Vane pump: divided into double-acting vane pump and single-acting vane pump. The pump has uniform flow, stable operation, low noise, high pressure and volumetric efficiency compared to the gear pump, and the structure is more complicated than the gear pump.
Piston pump: high volumetric efficiency, small leakage, can work under high pressure, mostly used in high-power hydraulic systems; but the structure is complex, the material and processing precision are high, the cost is high, and the cleanliness of oil is high.
The plunger pump is generally used when the gear pump and the vane pump are not satisfactory. There are also some other forms of hydraulic pumps, such as screw pumps, but the application is not as general as the above three .
