Hvad er de typer hydrauliske gearpumper

1. ekstern gearpumpe
The external gear pump consists of a housing, a driving gear, a driven gear, an end cap, etc. During the process where the driving gear drives the driven gear to rotate together, in the suction area, the teeth separate from each other, resulting in an increase in volume and a decrease in pressure, allowing hydraulic oil to enter. After rotation, the hydraulic oil is transported to the discharge area, Hvor geartænderne er indlejret med hinanden, tvinger den hydrauliske olie ud .

2. intern gearpumpe
Den indvendige gearpumpe består også af to gear, en inde og et udenfor, med den roterende skaftforskydning . Køretøjet er et ydre gear med en mindre diameter, der driver den ydre indre hjulfælge til at rotere i samme retning . i olieudgangen, pladsen mellem tænderne bliver større, hvilket gør det muligt for hydraulololie at komme ind i {{}}} til at gå i gang til pladsen til pladsen, der er større. Rummet mellem tænder falder, og olien presses ud .

3. Skrue gearpumpe
The sealing chamber is composed of a shell, an active screw, and a driven screw. As it rotates, the sealing chamber moves from one end to the other, causing hydraulic oil to flow in the axial direction. The discharged hydraulic oil flow rate is fixed, independent of the screw position, with no significant pressure changes and low noise.
