METHOD AND DEVICE FOR FIXING AND SYNCHRONISING ROTARY PISTONS IN A ROTARY PISTON PUMP

摘要

The invention relates to a method and to a device for fixing and synchronising rotary pistons in a rotary piston pump. The rotary pistons are housed in the pump chamber of the rotary piston pump. A shaft stub of each rotary piston is then pushed through a pump rear wall onto a drive shaft provided for the respective piston. The rotary pistons are aligned and synchronised in the pump chamber using a template, wherein the template is detachably fastened to a pump housing. After the synchronisation, the shaft stub of each rotary piston is non-positively connected to the respective drive shaft outside the pump chamber by means of a respective clamping apparatus.
