Traffic to80/min, The pressure is up to 700 bar, depending on the specifications.

Overview

A hydraulic pump is a device that converts mechanical energy into hydraulic energy based on the principle of volume(DIN ISo 1219)。 This sample

The pump introduced is a quantitative pump.

application

Hydraulic pumps mainly provide pressure oil for the actuating components of hydraulic systems. The maximum power is30kW, Depending on the specifications

And determined.

structure

The cylinder body of the radial piston pump is arranged in a star shape and adopts valve type flow distribution. The cylinder body can be configured as a single row, double row, or

Multiple rows driven by eccentric shafts located on the main shaft(plunger oil pressure stroke), reset is achieved by springs (plunger oil suction stroke)

Cheng）The output oil of each plunger is collected in the pressure oil collecting plate and output through a common pressure output port.

The casing of the pump serves as the support for the cylinder body and bearings. The pump has undergone rigorous static and dynamic balance tests, and therefore operates

Extremely stable. Except for single cylinder pumps and double cylinder pumps, Each row has a single cylinder count, so the output pulsation can be large from three cylinders onwards

To reduce.

fixed form Connect with flange end face

pipeline connection Pipe thread according toDIN IS0228/1. Connection dimensions refer to Section 3 Dimensional Drawings

Drive and rotation direction Driven by an elastic coupling, the rotation direction can be arbitrary, as shown inFlow direction

speed range Continuously forFrom 100 to 2000 revolutions per minute, it is allowed to reach 2800 revolutions per minute in a short period of time, but at this speed, it should be noted that only couplings, flanges, housings, etc. (D 6010H) can be provided for motors ranging from 71 to 200 liters. The power that matches the motor (DIN 42677) may need to be reduced to its maximum achievable pressure due to the output flow rate being twice as high.

Installation location seeSection 4.1, Horizontal to Vertical Installation

Flow direction The suction and discharge ports are fixed and independent of the direction of rotation

Installation Instructions

This pump, whether installed as a motor pump outside the fuel tank or inside the tank, serves as-When using a complete hydraulic pump station, attention must be paid

meaningThe position of the pump itself must be lower than the oil tank level. The cylinder body arranged in a star shape surrounds the pump casing and forms a closed device,

Therefore, the pump can only discharge normally during or after oil injectionE gas.

For detailed instructions on installation, exhaust, and operation, please refer toD6010H Sample Section 4.

Operating noise

The noise level curve shown represents the actual measurement results obtained in the laboratory. Tested smaller flow pumps within the same series(Smaller)

plunger diameter）The noise of the pump is generally below the curve range, while the noise of the pump with a larger flow rate (plunger diameter of 13-16mm) is usually close to the middle to upper range of the curve.

Measurement conditions:

Quiet room, with an interference sound level of approximately37dB(A), The measuring point is 1 meter away from the tested pump.

detectorA precision sound level measuring instrument that complies with DIN45633 standard. The oil viscosity during the detection process is about 50mm2/s

Instructions for using an R-type pump in a low-pressure oil tank (approximately 0... 0.5 bar or above)

The main shaft adopts two radial sealing rings placed on the journal as external seals. The standard shaft seal is arranged with two sealing lips facing each other. As a result, air will not enter the pump during oil suction(Low pressure zone), and even when the pump is located under the oil tank, the hydraulic oil (the self weight of the oil column generates a slight pressure inside the pump) will not leak out.

For fuel tank positions significantly higher than the pump(Several meters) or if the pump is located in a closed fuel tank and its pressure is often maintained above Ps>0.4 bar, two pumps with inward sealing lips can be provided. However, please note that pressures above 1 bar (2... 3 bar is also allowed) may affect the lifespan of the sealing ring or the starting frequency of the pump, and this type of seal can only be used in situations where it is not frequent.
