Disclosure of inventions

Objective of the claimed invention is to eliminate these disadvantages, namely the elimination of the offset of the frame relative to the installation of the axes of the unit due to the compensation of the shear (or shear) forces resulting from the pressure difference of the fluid in the inlet and outlet pipes, without the use of additional pumping equipment and electronics.

The problem is solved in that the system stabilization technological frame Assembly relative to the installation of axles mounted on the frame process unit in the form of a pump with inlet and outlet pipes and the electric motor includes at least two compensating cylinders and pipelines.

The number of compensating cylinders is determined by the overall and mounting dimensions, as well as the value of the shear force. Each of the cylinders has two cavities: one above the piston cylinder, and the other under the piston of the hydraulic cylinder.

The compensating cylinders installed between the frame process unit and the stationary base side inlet pipe near the vertical plane passing through the axis of the inlet pipe, and a cavity located above the piston of the hydraulic cylinders, connected m is waiting for him and outlet pipe, and cavity beneath the piston of the hydraulic cylinders are interconnected and lead pipe.

The implementation of the invention

The stabilization system frame process unit, consisting of pump 1, motor 2, frame 3, the inlet pipe 6 and the outlet pipe 7 contains the compensating cylinders 4, 5 with 8 pipelines.

The stabilization system frame process unit operates as follows. In the pumping of liquid through the pump 1 in the inlet and outlet pipes there is a pressure difference that causes shear force F, deforming the inlet pipe 6 and the outlet pipe 7 and the shifting frame 3 process unit relative to the installation axis of the unit. Simultaneously, the pumped liquid from the discharge pipe 7 through the piping 8 enters the cavity of the cylinder above the piston, and the fluid being pumped from the inlet pipe 6 enters the cavity of the cylinder beneath the piston. As a result, in each hydrophilite develops uniform pressure equal to the pressure difference in outlet and inlet pipes, which leads to a compensating force. The diameters of the cylinders are determined by the equality of the shear force F and compensating forces by the formula d=2Fpπ,mm,

where p is the pressure difference between the liquid inlet and at the outlet of the pump. PA.
