Seal for Oil-Free Rotary Displacement Compressor

Номер: US20130075975A1
Автор: Hilaris John A., Liarakos Nicholas P.
Принадлежит: HYDRO-ERGOSEAL INC.

Non-contacting cartridge shaft seals prevent leakage loss of process gases in an “oil free” rotary screw compressor or blower, while simultaneously preventing ingress of lubricating oil to the pumping chamber, allowing the compressor/blower to generate process pressure differentials without oil contamination. A compact unitized seal cartridge assembly is provided in the end plates of the pump housing. One of the rotor shafts extends through an aperture in the end plate or housing, between the pumping chamber and oil-lubricated gear/bearing cases. Internal elements have the ability to self-align radially achieving essential concentricity with shaft rotational axes. The rotor shafts or sleeves non-contact relationship during operation allow increased ranges of shaft rotational speeds. Air seal elements restrict flow of process air from the pumping or compression chamber, and oil seal elements with a directional spiral groove on the inside diameter prevent the leakage of lubricating oil to the process or atmosphere. 1. A seal cartridge for use in rotary displacement compressor , the compressor having a compressor chamber between two shaft bearings , comprising:a) a cartridge carrier disposed in a seal cavity and around a shaft capable of housing at least two self aligning seal rings, the cartridge carrier including a fluid communication path in fluid communication with the environment outside the seal cavity, the shaft having a closely controlled outer diameter surface;b) a first oil seal ring disposed within a cartridge cavity at least partially defined by an inner diameter of said cartridge carrier and sealing between a fluid communication path side and a shaft bearing side, the first oil seal ring being statically sealed against a surface of said cartridge carrier, the first oil seal ring further comprising a spiral groove in a machined inner diameter surface thereof, the machined inner diameter surface having very close tolerances, and the spiral grooves being ...

The seal is displaceable along the delivery path, by a movement of the eccentric, in a delivery direction from the inlet to the outlet to deliver the liquid. The pump is configured such that within the pump a friction torque that must be overcome for the eccentric to move is greater than a maximum pressure torque that can be generated by pressurized liquid in the delivery path, so as to prevent movement of the eccentric counter to the delivery direction.

The vane pump assembly includes a housing with an inner wall that surrounds an open chamber. A rotor is rotatably disposed in the open chamber and has a circular shape when viewed in cross section. A first pair of vanes are received in the rotor and are operably connected with one another by a first bell crank which is pivotable about a pivot axis such that movement of one vane inwardly into the rotor causes the other vane to move outwardly out of the rotor to maintain both vanes in contact with the inner wall as the rotor rotates relative to the housing during operation of the vane pump assembly.

The present invention relates to a variable displacement gerotor pump. The variable capacity girotor pump according to the present invention adjusts the discharge amount per rotation by changing the meshing width of the two gears by moving one of the two gears meshed inside the casing in the axial direction in the conventional girotor pump. A gear ring at one end of the moving gear and a gear block at the other end prevent fluid leakage. In addition, when a hydraulic chamber is formed on one side of the gear block and the fluid is introduced, the pressure of the discharged fluid and the discharge amount per time can be easily maintained within a certain range. The structure of the variable capacity gerotor pump according to the present invention can be used as a variable capacity gerotor motor as it is. It can be used in continuously variable transmissions and power distribution devices.

Rotary pump using variable impeller

The present invention relates to a rotary pump using a variable impeller. The rotary pump comprises: a cylindrical housing having a fluid inlet formed in one side thereof and a fluid outlet formed in the other side thereof; a rotor accommodated in the housing and rotating around the same axis as the housing; and a variable impeller having one end rotationally coupled to the rotor and the other end pumping a fluid by making surface contact with the inner circumferential surface of the housing by centrifugal force. The inner circumferential surface of the housing includes: a pumping guide part having a predetermined curvature; a discharge guide part having a reduced curvature while continuing with the pumping guide part; and a suction guide part having an increased curvature while continuing with the discharge guide part, and continuing with the pumping guide part. A sweeping part having the same curvature as the pumping guide part is formed at the other end of the outer surface of the variable impeller. As the variable impeller rotates along the suction guide part, the variable impeller suctions the fluid from the fluid inlet while moving far away from the rotor. As the variable impeller rotates along the pumping guide part, the variable impeller transports the fluid with a gap between the variable impeller and the rotor. As the variable impeller rotates along the discharge guide part, the variable impeller discharges the fluid to the fluid outlet while being folded on the rotor. Therefore, the rotary pump can pump a high-pressure fluids without pressure leakage.
