The Oil Pump Supply Module is part of an equipment series that facilitates the investigation of a wide range of engines and machines. The flow is adjusted on a pressure valve and recorded using an oval wheel meter. Other sensors measure the temperature, intake and delivery pressure. Different oil pumps can be operated on the supply module and investigated in terms of their characteristic behaviour. The corresponding sensor connections and digital displays are located on the measuring equipment block. The pumps are connected into the experimental set-up using hydraulic hoses with quick action couplings.

Delivery pressure
Flow rate.
The Oil Return In Refrigeration Systems is of key importance for the service life of the compressor and thus for a secure constant supply of refrigeration. In the vaporised refrigerant the oil remains liquid in the lower parts of the system. This can result in lack of oil in the compressor. To return the oil to the compressor, a minimum velocity must be maintained in the pipes. A small diameter of the rising pipe results in a high velocity and ensures the return of the oil even under partial load. However, at full load the pressure loss increases due to the small diameter. The velocity in the rising pipe depends on the pipe diameter and the refrigerant mass flow. In most compressors some lubrication oil is carried along with the compressed refrigerant. In the liquid refrigerant the oil is dissolved in the refrigerant and is transported without problems. If the velocity in the rising pipe on the intake side of the compressor is too low (partial load), the oil is not returned to the compressor due to its higher density.
