Hydraulic Pumps

Hydraulic pumps are a heart of Hydraulic system because hydraulic pumps are a components and accessories that change machanical force to hydraulic oil force. Hydraulic pumps have 3 type

  1. Gear pump
  2. Vane pump
  3. Piston pump

Gear pump

Gear pump are a popular pump in this time. The strength of this pump are a small and light weight, not complicated structure, easy to maintain. This pump can made a max pressure at 210 - 250 bar, max displacement at 1 - 200 c.c./rev and and Gear pump have a 2 type.

  • Internal Gear Pump
  • This pump have a gear and rotor in there. internal gear pump have a max pressure at 140 - 300 bar, max displacement at 20 - 64 c.c./rev RPM 200 - 2,500 rpm and this pump can decrease electric power at 35%. Process of internal gear pump

Process of internal gear pump
  • External gear pump
  • This pump have a 2 gear in there. External gear pump have a max pressure at 2,000 - 4,200 MPa, max displacement at 0.6 - 90 c.c./rev.

Vane pumps

Vane pumps have a special feature its have a high displacement and appropriate to use with high displacement work but low pressure and medium pressure.

Rotary-vanepump-diagram
ส่วนประกอบของปั๊มแบบใบพัด (Vane Pump)

Vane pump have a 2 type.

  • Fix displacement vane pump. This pump use a vane push hydraulic oil to made a displacement. This pump can adjust a pressure and displacement.
  • The pressure can adjust at Relief valve on the pump. This pump can made a max pressure at 70 bar (low pressure series) and 140 bar (medium pressure series).

Piston pumps

Piston pumps are a one of popular pump because its have a high durable, have many displacement to choose and it can made a max pressure at 160 bar (medium pressure series) and 350 bar (High pressure series) and this pump has save energy and save the power of motor 50% more than the other pump. This pump are appropriate with high pressure and high displacement.

Hydraulic External Gear Pumps - Model. 1A Series

Group 1 product is defined by the mounting flange and shaft end. Mounting flanges can be the SAE “ AA” two bolt, the US 4F-17 four bolt, four bolt European mounting flanges, and the “through-bolt” front manifold discharge DC power-pack design pump. Shaft ends can be keyed, spline, or tang depending on the customer requirement, Displacements offered are from .04 to .82 cubic inch per revolution depending on the specific model. Side ports are generally standard but rear ports can be available depending on the specific model.
