The Tokimec SQP series is a well - known hydraulic vane pump widely used in various industrial applications. These pumps are designed to handle hydraulic oil and provide reliable fluid power transmission.
Displacement
The SQP series pumps come in different displacement options. The displacement range typically varies depending on the specific model within the series. For example, it can range from a few cubic centimeters per revolution (cc/rev) to a relatively larger displacement value. This allows for flexibility in matching the pump's output to the specific requirements of the hydraulic system.
Pressure Ratings
Rated Pressure: The pumps usually have a rated working pressure. This is often in the range of several megapascals (MPa). For example, a common rated pressure for many SQP pumps could be around 7 - 14 MPa. This rated pressure indicates the maximum continuous pressure that the pump can handle under normal operating conditions without significant wear or damage.
Peak Pressure: In addition to the rated pressure, there is also a peak pressure value. The peak pressure, which the pump can withstand for a short period (such as during transient operations or sudden load changes), is higher than the rated pressure. It might be around 16 - 21 MPa for some models.
Speed Range
The SQP series pumps have a specified operating speed range. The minimum speed is designed to ensure proper lubrication and priming of the vanes. It can be as low as a few hundred revolutions per minute (rpm), typically around 500 - 800 rpm. The maximum speed is limited by factors such as centrifugal forces acting on the vanes and the ability to maintain efficient fluid transfer. It usually ranges from 1500 - 3000 rpm.
Vane Design and Construction
The vanes of the SQP series pumps are carefully designed. They are usually made of a material with good wear resistance and flexibility, such as a composite material or a special alloy. The vanes have a specific shape and thickness to ensure efficient contact with the pump housing and reliable fluid displacement. The number of vanes can vary, but it is typically in the range of 8 - 12 vanes, which helps to provide a more stable flow and reduce pulsation.
