Hydraulic pump providing enhanced physical mobility
View Patent ↗A piston-driven pump apparatus configured to transfer liquid-based abrasive materials via a pressurized hydraulic medium which is capable of physical manipulation between remote material reservoirs. The apparatus exhibits a remotely tethered double-acting pump having independence from a fluidic supply source. The pump is configured to be removed from a first material reservoir and placed in communication with a second material reservoir by physical manipulation. The apparatus has a cylindrical sleeve assembly which has a wearing sleeve which may be removed and/or rotated to increase the operational time of the apparatus before an end-of-life replacement of the sleeve is required. The apparatus diminishes a pulsation effect of conventional double-acting piston pumps via a compressible pressure sleeve which is capable of deformation within a pump housing. A metering device is present to control the external flow of abrasive material, providing back pressure against an internal compressible sleeve.
1 . A method for implementing the installation of drywall taping, finishing, and texturing materials via an abrasive materials pumping apparatus comprising:
mixing drywall compound within a reservoir;
submerging a lower-most end of the pumping apparatus into the reservoir;
connecting an application tool to a first end of a material supply hose;
connecting a second end of the material supply hose to the pumping apparatus;
connecting the pumping apparatus to a remote hydraulic pump system;
activating a pump motor of the pumping apparatus, causing pressure to build within at least one material passageway within the pumping apparatus;
the remote hydraulic pump system supplying hydraulic fluid to the pumping apparatus through a reciprocating valve leading to the pump motor;
wherein hydraulic fluid pressure is preset through a relief valve on the remote hydraulic pump system;
abrasive material flowing through passageways within the pumping apparatus due to the application of built pressure;
abrasive material moving out of the pumping apparatus through an exiting port into the material supply hose;
air exiting out of the pumping apparatus through an air output port into an independent air hose;
wherein said material supply hose and said independent air hose are terminated by an application tool;
the independent air hose supplying pneumatic pressure to the application tool; and
a valve metering the abrasive material as the abrasive material exits the pumping apparatus into the material supply hose via at least one exiting port.
2 . The method of claim 1 , wherein the application tool is a continuous flow system tool.
3 . The method of claim 1 , wherein the application tool is a texture application tool.
4 . The method of claim 3 , wherein the wearing sleeve is twice as long as a linear stroke length of the pump motor of the pumping apparatus.
5 . The method of claim 4 , further comprising:
removing a wearing sleeve upon an indication of wear;
rotating the wearing sleeve 180 degrees; and
reinstalling the wearing sleeve.
6 . The process of claim 1 , further comprising:
activating the application tool; and
the abrasive material evenly flowing out of the application tool via the compressed air activation of a material valve.
7 . The process of claim 6 , further comprising:
deactivating the application tool;
a relief valve closing within the pumping apparatus;
said reciprocating valve of the remote hydraulic pump system stalling,
preventing the pump motor from cycling; and
the abrasive material hose maintaining pressure.
8 . The process of claim 7 , further comprising:
activating the application tool;
a material valve of the application tool opening while simultaneously supplying a signal to a relief valve of the remote hydraulic pump system;
the relief valve opening;
said relief valve allowing hydraulic fluid to flow into a reciprocating valve of the pump motor, causing the pump motor to cycle.
