SD1B2020R720 0515-0661 Hydraulic Gear Pump

Specific Details:

The SD1B2020R720 0515-0661 hydraulic gear pump is a hydraulic transmission device that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gears to transport fluid or increase its pressure.

I. Working Principle

The working principle of the hydraulic gear pump is based on the meshing and rotation of gears. It usually consists of two or more meshing gears, one of which is the drive shaft (driving gear), and the other is the driven shaft (driven gear). When the drive shaft rotates, the space volume on the disengagement side of the gears changes from small to large, forming a vacuum and drawing in liquid; the space volume on the meshing side of the gears changes from large to small, squeezing the liquid into the pipeline. This process continues continuously, providing a continuous discharge at the pump outlet.

II. Structural Characteristics

The hydraulic gear pump has a compact structure and is convenient to use and maintain. It typically includes components such as the pump casing, locating pin, rear cover, drive shaft, driven shaft, and gears. The rear cover is fixedly connected to the pump casing through the locating pin. The interior of the pump casing has a left chamber and a right chamber where the driven gear and driving gear are installed, respectively. The driven gear and driving gear mesh with each other to form a working volume.

III. Performance Parameters

The performance parameters of the hydraulic gear pump vary by model and manufacturer but commonly include flow rate, pressure, and rotational speed. For example, some models of hydraulic gear pumps have a flow rate range of 1-200 mL/r, a pressure range of up to 25 MPa, and a rotational speed range of 500-4000 rpm. Specific parameters should be selected based on actual application requirements and equipment specifications.

IV. Application Fields

Hydraulic gear pumps are widely used in various hydraulic systems, such as those in the petroleum, chemical, shipping, power, grain and oil, food, medical, building materials, metallurgical, and national defense research industries. They are suitable for transporting lubricating oils or other liquids with similar properties that do not contain solid particles or fibers, are non-corrosive, and have temperatures not exceeding a certain range.

V. Usage Precautions

1. When using the hydraulic gear pump, ensure that the line voltage does not exceed ±10% of the voltage specified on the pump's nameplate.

2. Check the appearance of each component before use to ensure it is intact before starting the pump.

3. The hydraulic gear pump should not be operated empty, and the pump should be stopped immediately after pumping is complete.

4. Regularly inspect and replace worn components such as brushes and bearings.

5. Prevent overload and overspeed operation to avoid damaging the pump body and gears.

In summary, the SD1B2020R720 0515-0661 hydraulic gear pump, as a common hydraulic transmission device, has a wide range of applications and significant technical value. When selecting and using it, factors such as its working principle, structural characteristics, performance parameters, and usage precautions should be fully considered.
