The present application provides a force measuring platform for performing hydraulic tests on a shaftless suspension pump, comprising: a bracket, which has a first support plate, a second support plate and is connected between the first support plate and the second support plate The positioning device, located on the first support plate, is used to support the pump casing and adjust the position of the pump casing on the first support plate; the drive unit, arranged on the second support plate of the bracket, includes The drive shaft extending downward from the second support plate, the lower end of the drive shaft can extend into the pump casing through the medium inlet of the pump casing and be connected with the impeller; the force measuring component is fixed on the support beam and connected with the drive shaft. The force measuring platform provided by this application can test the force of the impeller after the impeller is displaced relative to the pump casing in the full working range, so as to obtain the force range of the impeller at the full working point position, which is helpful for the control system of the magnetic levitation motor. Adjustments are made to achieve precise control of the impeller.
Description
technical field [0001] The present application relates to the technical field of medical device testing equipment, and more particularly, to a force measuring platform used for hydraulic testing of a shaftless suspension pump. Background technique [0002] Heart failure is a prevalent and life-threatening disease with a one-year mortality rate of approximately 75% once it progresses to an advanced stage. Given the limited number of cardiac donors for advanced heart failure, ventricular assist device (VAD) technology has emerged as a viable treatment option, or as an alternative, bridging the gap between patients and transplant surgery. [0003] When the heart loses its pumping function (such as cardiac arrest surgery, acute, cardiogenic shock, etc.), a blood pump can be used to replace the heart to assist in maintaining human blood circulation. At present, blood pumps are divided into implantable blood pumps and extracorporeal blood pumps according to their implantability a...
