福建ENGINE VARIABLE OIL PUMP

Powder Metallurgy Injection Molding Group has more than 60 years of PM production experience, and produces a large number of oil pump parts every year. The first is to produce the inner and outer rotors of motor oil pumps. The following is the development history of the Group's production of oil pumps

1994 Mass production of inner and outer rotors of motorcycle oil pump

Mass production of oil pump gears in 1995

Mass production of internal and external rotors of automobile oil pumps in 1997

1998 Mass production of stator rotor port plate of hydraulic power steering pump

In 2006, mass production of sliding sleeve of variable displacement oil pump rotor and internal and external rotors of gearbox oil pump

Volume production of internal and external rotors of gasoline fuel pump in 2008

Mass production of automobile gear variable displacement pump gear in 2012

In 2013, mass production of sliding sleeve of rotor of variable displacement pump of automobile vane type, and mass production of rotor, stator and oil distribution plate of double acting vane pump of gearbox

Characteristics of engine variable displacement oil pump

1) The fuel consumption is reduced by about 3%: the oil pump displacement is reduced, the oil supply pressure is reduced, and the overall efficiency of the oil pump is improved;

2) Better NVH performance to meet the comfort requirements of end customers;

3) Precision equipment and high-precision molds: higher precision dimensional tolerance and geometric tolerance

4) High performance materials and high-end equipment ensure the customer's product strength under higher pressure conditions

Hydraulic power steering pump powder metallurgy parts - double acting vane pump

1. The double acting vane pump has the advantages of compact structure, uniform flow, balanced radial force, low noise and stable operation.

2. It is sensitive to oil pollution.

3. The rotor slot is grinded by an imported slot grinder with high precision. （0.014）

4. The stator inner cavity is processed by imported curve grinder with high accuracy. (Profile 0.05)

5. The size and shape tolerance of stator, rotor and oil distribution plate shall reach high accuracy after double end grinding.

6. The product requires high cleanliness, and no particles above 600um are allowed.

7. The special shape of the end face of the oil distribution plate shall be guaranteed.
