Oem A2fo Rexroth Pump A2fo28/61l-nbd55*sv* Excavator

Description:

Rexroth variable piston pump features the use of double piston structure, small pressure fluctuation, using imported stones and gem ball plunger, ensure precise flow, through the communication with the computer RS232 interface, can be directly controlled by computer. The real-time display of the current pressure and the set pressure, set the flow rate; real time curve display pump working pressure, according to the two set of flow and pressure, quick and practical; has the function of timing, convenient to set the pump working time can be saved; the current work pressure, easy to view; the important parameters can be printed in the current pressure.

Piston pump products are widely used in petroleum exploration and development of catalytic evaluation experiments, petroleum chemical reaction, reaction, food, pharmaceutical, liquid chromatography, supercritical fluid extraction, separation, atomic energy science, environmental science, technology and equipment, laboratory equipment and various liquid micro quantity liquid etc.. The performance indexes of TBP series advection pump can meet the research requirements of fluid seepage and rheological characteristics of oil field, and fill gaps in equipment manufacturing of related experimental technology fields in China, and achieve the international advanced level of similar instruments.

A2FO:

The oil outlet valve and the oil outlet seat are also a pair of precision pairs, which can not be interchanged after paired grinding, and the matching clearance is 0.01mm. The oil outlet valve is a one-way valve. Under the action of the spring pressure, the conical surface of the valve is tightly matched with the valve seat. Its function is to isolate the high pressure oil pipe from the upper end cavity of the plunger when stopping the supply, so as to prevent the oil in the high-pressure oil pipe from flowing into the fuel injection pump. The lower part of the oil outlet valve is cross section, which can both guide and pass through the diesel. There is a small cylindrical surface under the cone of the oil outlet valve, which is called the decompression belt. Its function is to make the oil pressure in the high pressure oil pipe drop rapidly at the end of the oil supply, so as to avoid the phenomenon of dropping oil at the nozzle hole. When the belt falls into the seat, the upper volume increases rapidly, and the pressure is rapidly reduced and the spray is stopped quickly.

Features:

1. The quantitative axial piston pump with oblique axis design is suitable for the hydraulic transmission in the open road.

2. Crankshaft design is more suitable for mobile or fixed applications.

3, The flow rate is proportional to the transmission speed and displacement.

4. The design of shaft bearings is specially designed to provide reliable service life for specific application fields.

5. High power;

6, Compact design;

7, Comprehensive and efficient;

8. Economic concept;

9. A plunger uses a plunger ring.

10. The pressure range is wide;

Displacement: 315bar peak pressure /350bar pressure peak pressure

10-200 displacement: 400bar pressure /450bar peak pressure

250-1000 displacement: 350bar pressure /400bar peak pressure
