Abstract
A portable descaling apparatus for creating a forceful fluid flow through passages of a heat exchanger may comprise a cart, a fluid tank mounted on the cart and having an interior configured to hold a quantity of fluid, a fluid pump mounted on the cart and being configured to pump fluid from the tank under pressure and a pump motor mounted on the cart and being connected to the fluid pump to operate the pump.
Claims6
A portable descaling apparatus for creating a forceful fluid flow through passages of a heat exchanger, the apparatus comprising:
- a cart including:
- a platform having a front, a rear, and a pair of opposite sides, the platform having a forward leg structure;
- a pair of wheels mounted on an axle mounted on the platform, each of the wheels being positioned at one of the sides of the platform, the axle being located on the platform rearwardly of the forward leg structure;
- and
- a handle mounted on and extending upwardly from the platform, the handle being positioned toward the rear of the platform rearward of the axle;
- a fluid tank mounted on the cart and having an interior configured to hold a quantity of fluid;
- a fluid pump mounted on the cart and being configured to pump fluid from the fluid tank under pressure;
- a pump motor mounted on the cart and being connected to the fluid pump to operate the fluid pump;
- wherein the fluid pump is located on the platform over and in vertical alignment with the forward leg structure, the pump motor being mounted on the fluid pump in a manner such that the pump motor is located over and in a vertical alignment with the fluid pump and also the forward leg structure of the platform to support the weight of the fluid pump and pump motor on the forward leg structure;
- and
- wherein the fluid tank is positioned on the platform above the axle and at least partially between the wheels with equal portions of the fluid tank being located forward and rearward of the axle such that rearward tilting of the platform shifts a greater portion of the weight of the fluid tank and contents of the fluid tank rearwardly of the axle to balance the weight of the motor and the fluid pump.

A descaling system comprising:
- a heat exchanger with a pair of connections in fluid communication with a fluid passage through the heat exchanger, the connections including an inlet connection and an outlet connection;
- and
- a portable descaling apparatus for creating a forceful fluid flow through passages of the heat exchanger, the apparatus comprising:
- a cart including:
- a platform having a front, a rear, and a pair of opposite sides, the platform having a forward leg structure;
- a pair of wheels mounted on an axle mounted on the platform, each of the wheels being positioned at one of the sides of the platform, the axle being located on the platform rearwardly of the forward leg structure;
- and
- a handle mounted on and extending upwardly from the platform, the handle being positioned toward the rear of the platform rearward of the axle;
- a fluid tank mounted on the cart and having an interior configured to hold a quantity of fluid, the fluid tank having a tank inlet and a tank outlet;
- a fluid pump mounted on the cart and being fluidly connected to the tank outlet to pump fluid from the fluid tank under pressure, the fluid pump having an output;
- a pump motor mounted on the cart and being connected to the fluid pump to operate the fluid pump;
- an input assembly configured to receive fluid into the apparatus from the heat exchanger during fluid circulation, the input assembly comprising:
- an input connector mounted on the cart and being removably connected to the output connection of the heat exchanger to fluidly connect the fluid tank to the heat exchanger;
- and
- a conduit fluidly connecting the input connector to the tank inlet;
- and
- an output assembly configured to receive fluid from the output of the fluid pump, the output assembly comprising:
- an output connector mounted on the cart and being removably connected to the input connection of the heat exchanger to fluidly connect the fluid pump to the heat exchanger;
- and
- a conduit fluidly connecting the output connector to the pump outlet;
- wherein the fluid pump is located on the platform over and in vertical alignment with the forward leg structure, the pump motor being mounted on the fluid pump in a manner such that the pump motor is located over and in a vertical alignment with the fluid pump and also the forward leg structure of the platform to support the weight of the fluid pump and pump motor on the forward leg structure;
- and
- wherein the fluid tank is positioned on the platform above the axle and at least partially between the wheels with equal portions of the fluid tank being located forward and rearward of the axle such that rearward tilting of the platform shifts a greater portion of the weight of the fluid tank and contents of the fluid tank rearwardly of the axle to balance the weight of the motor and the fluid pump.
