Description

Fluid pump

Technical Field

The present disclosure relates to a fluid pump, and more particularly to operational aspects of the fluid pump.

Background

In general, a fluid pump, such as a water pump, may include a plurality of controls disposed on the fluid pump, such as pump speed controls, pump flow controls, automatic/manual controls, clean/dirty fluid operation, and the like. In many cases, the location of the controls provided on the fluid pump may be non-ergonomic, making it difficult for a user to operate the controls. For example, in some submersible fluid pumps, the control member may be located within a fluid-tight housing. In such a case, it may be necessary to completely remove the fluid pump from the fluid in order to be able to operate the control member. In many cases, the fluid-tight housing may have a complex structure, providing a laborious and time-consuming method for controlling the fluid pump.

In some embodiments, a user may have to operate a complex mechanism during switching of the fluid pump between the clean fluid operating mode and the dirty fluid operating mode. For example, it may be necessary to adjust the base or inlet of the fluid pump to provide an increased inlet area during dirty fluid operation, or a reduced inlet area during clean fluid operation. In such cases, the complex mechanism may provide a laborious and time-consuming method to switch the fluid pump between the clean fluid operating mode and the dirty fluid operating mode. Accordingly, there is a need for an improved fluid pump for such applications.

According to an embodiment of the invention, the at least one operational characteristic of the fluid pump is a clean fluid operation of the fluid pump and a dirty fluid operation of the fluid pump. Accordingly, the fluid pump may be easily and ergonomically switched between a clean fluid mode and a dirty fluid mode based on user needs, thereby improving usability.

According to an embodiment of the invention, the base is adapted to be releasably locked in the retracted position relative to the housing in one of the first and second positions of the second part. The retracted position of the base is associated with clean fluid operation of the fluid pump.

The housing 102 has a substantially hollow, elongated, stepped, and cylindrical configuration. In other embodiments, the housing 102 may have any other configuration based on the overall configuration of the pump 100. The housing 102 is adapted to enclose one or more internal components (not shown) of the pump 100, such as a motor, rotor, blades, impeller, bearings, fluid passages, electrical/electronic components, controllers, and the like. The housing 102 may be made of any material, such as metal, polymer, and/or combinations thereof. The housing 102 may be manufactured using any process, such as molding, casting, assembly, additive manufacturing, and the like.

The pump 100 includes a base 104. The base 104 has a substantially hollow configuration. The base 104 is movably coupled to the housing 102 such that the base 104 is adapted to move axially along the longitudinal axis X-X' relative to the housing 102. The base 104 includes a primary inlet (not shown) disposed on a bottom portion 106 of the base 104. The base 104 also includes a plurality of secondary inlets 108 disposed on a side portion 110 of the base 104. Each of the primary and secondary inlets 108 is adapted to allow fluid to flow into the housing 102 via the base 104. The base 104 may be made of any material, such as metal, polymer, and/or combinations thereof. The base 104 may be manufactured using any process, such as molding, casting, assembly, additive manufacturing, and the like. The base 104, primary inlet and secondary inlet 108 will be described in more detail later.

The pump 100 also includes a fluid outlet 112. A fluid outlet 112 is provided on the housing 102. In the illustrated embodiment, the fluid outlets 112 are substantially parallel and spaced apart with respect to the longitudinal axis X-X'. In other embodiments, the fluid outlet 112 may be disposed at any orientation and at any location on the housing 102. The fluid outlet 112 is fluidly coupled to each of the primary and secondary inlets 108 via the base 104. Thus, the fluid outlet 112 is adapted to provide for the egress of fluid from the housing 102 and the pump 100.

The pump 100 also includes a handle portion 114. The handle portion 114 is disposed on the housing 102. The handle portion 114 is adapted to lift and/or move the pump 100. In the illustrated embodiment, the handle portion 114 has a substantially elongated and C-shaped configuration. In other embodiments, the handle portion 114 may have any other configuration, such as an L-shaped configuration, a curved configuration, or the like. Further, in the illustrated embodiment, the handle portion 114 extends substantially along the longitudinal axis X-X'. In other embodiments, the handle portion 114 may be disposed on the housing 102 in any other orientation based on application requirements. The handle portion 114 may be made of any material such as metal, polymer, and/or combinations thereof. The handle portion 114 may be manufactured using any process, such as molding, casting, assembly, additive manufacturing, and the like.

The handle portion 114 includes a first portion 116. The first portion 116 is fixedly coupled to the housing 102 via a plurality of

leg portions

118, 120. In the illustrated embodiment, the handle portion 114 includes two

leg portions

118, 120. In some embodiments, the handle portion 114 may include single or multiple leg portions, depending on the application requirements. The handle portion 114 also includes a second portion 122. The second portion 122 is movably coupled to the first portion 116. The movement of the second portion 122 relative to the first portion 116 is adapted to change one or more operating characteristics of the pump 100.

Referring to fig. 3A and 3B, in the illustrated embodiment, the second portion 122 is adapted to move along the longitudinal axis X-X' between a first position "P1" (shown in fig. 3A) and a second position "P2" (fig. 3B). In some embodiments, the second portion 122 may be adapted to be biased at a first position "P1" and adapted to be selectively moved to a second position "P2" by a user. In some embodiments, the second portion 122 may be unbiased and may be adapted to be selectively moved by a user at any one of the first position "P1" and the second position "P2". Additionally, in some embodiments, the second portion 122 may be adapted to move in one or more intermediate positions (not shown) between the first position "P1" and the second position "P2". In the illustrated embodiment, the second portion 122 is disposed on the first side 302 of the first portion 116. In other embodiments, the second portion 122 may alternatively be disposed on the second side 304 of the first portion 116 based on application requirements.

In some embodiments, the operational characteristics of the pump 100 may include activation and deactivation of the pump 100. In such a case, the second portion 122 of the handle portion 114 may be associated with an electrical/electronic switch (not shown) adapted to activate and deactivate the pump 100. More specifically, in one embodiment, the second portion 122 may be adapted to deactivate the pump 100 in the first position "P1" of the second portion 122. Further, in the second position "P2" of the second portion 122, the second portion 122 may be adapted to activate the pump 100. Alternatively, in another embodiment, the second portion 122 may be adapted to activate the pump 100 in the first position "P1" of the second portion 122. In such a case, the second portion 122 may be adapted to deactivate the pump 100 in the second position "P2" of the second portion 122.

In some embodiments, the operational characteristics of the pump 100 may include the enablement of manual and automatic modes of the pump 100. In such a case, the second portion 122 of the handle portion 114 may be associated with an electrical/electronic switch (not shown) adapted to switch the pump 100 between the manual mode and the automatic mode. More specifically, in one embodiment, in the first position "P1" of the second portion 122, the second portion 122 may be adapted to enable a manual mode of the pump 100. Further, in the second position "P2" of the second portion 122, the second portion 122 may be adapted to enable an automatic mode of the pump 100. Alternatively, in another embodiment, in the first position "P1" of the second portion 122, the second portion 122 may be adapted to enable an automatic mode of the pump 100. In such a case, at the second position "P2" of the second portion 122, the second portion 122 may be adapted to enable the manual mode of the pump 100.

In some embodiments, the operating characteristics of the pump 100 may include variable speed control of the pump 100. In such a case, the second portion 122 of the handle portion 114 may be associated with an electrical/electronic switch (not shown) adapted to variably control the speed of the pump 100 from a first speed to a second speed. The first speed may be higher or lower relative to the second speed based on application requirements. More specifically, in one embodiment, in the first position "P1" of the second portion 122, the second portion 122 may be adapted to control the pump 100 at a first speed. Further, in the second position "P2" of the second portion 122, the second portion 122 may be adapted to control the pump 100 at a second speed. Alternatively, in another embodiment, the second portion 122 may be adapted to control the pump 100 at a second speed at a first position "P1" of the second portion 122. In such a case, at the second position "P2" of the second portion 122, the second portion 122 may be adapted to control the pump 100 at the first speed.

In some embodiments, the electrical/electronic switch may be adapted to variably control the speed of the pump 100 at one or more intermittent speeds between the first speed and the second speed. In such a case, the second portion 122 of the handle portion 114 may be adapted to move between one or more intermediate positions between the first position "P1" and the second position "P2" to variably control the speed of the pump 100 at one or more intermittent speeds between the first speed and the second speed. Thus, when the first speed may be higher than the second speed, the second portion 122 may be adapted to gradually decrease the speed of the pump 100 from the first speed to the second speed as the second portion 122 may gradually move from the first position "P1" to the second position "P2". Alternatively, when the first speed may be lower than the second speed, the second portion 122 may be adapted to gradually increase the speed of the pump 100 from the first speed to the second speed as the second portion 122 may gradually move from the first position "P1" to the second position "P2".

In some embodiments, the operating characteristics of the pump 100 may include variable flow control of the pump 100. In such a case, the second portion 122 of the handle portion 114 may be associated with an electrical/electronic switch (not shown) or a flow control valve (not shown) adapted to variably control the flow of the pump 100 from a first flow rate to a second flow rate. The first flow rate may be higher or lower relative to the second flow rate based on application requirements. More specifically, in one embodiment, at the first position "P1" of the second portion 122, the second portion 122 may be adapted to control the pump 100 at a first flow rate. Further, in the second position "P2" of the second portion 122, the second portion 122 may be adapted to control the pump 100 at a second flow rate. Alternatively, in another embodiment, the second portion 122 may be adapted to control the pump 100 at a second flow rate at the first position "P1" of the second portion 122. In such a case, at the second position "P2" of the second portion 122, the second portion 122 may be adapted to control the pump 100 at the first flow rate.

In some embodiments, an electrical/electronic switch or flow control valve may be adapted to variably control the flow of the pump 100 between one or more intermittent flows between a first flow and a second flow. In such a case, the second portion 122 of the handle portion 114 may be adapted to move between one or more intermediate positions between the first position "P1" and the second position "P2" to variably control the flow rate of the pump 100 between one or more intermittent flow rates between the first flow rate and the second flow rate. Thus, when the first flow rate may be higher than the second flow rate, the second portion 122 may be adapted to gradually decrease the flow rate of the pump 100 from the first flow rate to the second flow rate as the second portion 122 may gradually move from the first position "P1" to the second position "P2". Further, when the first flow rate may be lower than the second flow rate, the second portion 122 may be adapted to gradually increase the flow rate of the pump 100 from the first flow rate to the second flow rate as the second portion 122 may be gradually moved from the first position "P1" to the second position "P2".

In still other embodiments, the operating characteristics of the pump 100 may include clean fluid operation and dirty fluid operation of the pump 100. In such a case, the base 104 may be movable between an extended position "EP" (shown in fig. 1) to a retracted position "RP" (shown in fig. 2) based on the operating mode of the pump 100. Referring to FIG. 4, a partial cross-sectional view of the pump 100 is shown in the retracted position "RP". In the illustrated figures, a portion of the housing 102 of the pump 100 is omitted for clarity and illustration. In the first position "P1" of the second portion 122 of the handle portion 114, the base portion 104 is adapted to be locked in a retracted position "RP" within the housing 102.

More specifically, the second portion 122 of the handle portion is coupled to the locking mechanism 402. The locking mechanism 402 includes a first linkage member 404, a second linkage member 406, and a locking member 408. The first linkage member 404 is fixedly coupled to the second portion 122 of the handle portion 114. Further, the second linkage member 406 is fixedly coupled to the base 104. Further, a locking member 408 is movably coupled to the first linkage member 404 and releasably coupled to the second linkage member 406. In the first position "P1" of the second portion 122 of the handle portion 114, the locking member 408 locks the second linkage member 406, and thus the base 104, in the retracted position "RP" within the housing 102. In such a case, the pump 100 receives fluid flow through the primary inlet. In addition, each of the secondary inlets 108 is blocked by the housing 102. Thus, the first position "P1" of the second portion 122 of the handle portion 114 is associated with clean fluid operation of the pump 100.

Referring to fig. 5, a partial cross-sectional view of the pump 100 in the extended position "EP" is shown. In the illustrated figures, a portion of the housing 102 of the pump 100 is omitted for clarity and illustration. In the second position "P2" of the second portion 122 of the handle portion 114, the base portion 104 is released and locked in the extended position "EP". More specifically, movement of the second portion 122 of the handle portion 114 at the second position "P2" moves the first linkage member 404 axially along the longitudinal axis X-X'. Axial movement of the first linkage member 404 also moves the locking member 408 in the direction "D1" such that the second linkage member 406, and thus the base 104, is released to the extended position "EP". Further, as the second portion 122 of the handle portion 114 is moved to the first position "P1", the first linkage member 404 is moved axially to move the locking member 408 in the direction "D2" such that the second linkage member 406, and thus the base 104, is locked in the extended position "EP".

In such a case, each of the secondary inlets 108 of the base 104 is unobstructed by the housing 102. Accordingly, the pump 100 receives a fluid flow via each of the primary and secondary inlets 108. Each of the primary and secondary inlets 108 provides an increased inlet area for fluid to flow into the pump 100. Thus, the second position "P2" of the second portion 122 of the handle portion 114 is associated with dirty fluid operation of the pump 100 to cause debris, such as soil, slurry, etc., to flow with the water flow into the pump 100 via the increased inlet area. It should be noted that in other embodiments, clean fluid operation and dirty fluid operation of pump 100 may alternatively and/or interchangeably be associated with second position "P2" and first position "P1" of second portion 122 of handle portion 114, respectively, with appropriate modification of locking mechanism 402.

The pump 100 provides a simple, effective, and cost-effective method for switching the pump 100 between different operating modes. The second portion 122 of the handle portion 114 may be used to change the mode of operation of the pump 100, thereby improving ergonomics of operation of the pump 100. As described herein, the operational characteristics of the pump 100 that can be varied include, but are not limited to: activation/deactivation of the pump 100, activation of a manual/automatic mode of the pump 100, variable speed control of the pump 100, variable flow control of the pump 100, and switching of the pump 100 between clean/dirty fluid operation. Accordingly, any operating characteristics of the pump 100 may be controlled via the second portion 122 of the handle portion 114, thereby increasing versatility and flexibility. The second portion 122 of the handle portion 114 may be incorporated into any pump with minor modifications to existing systems and with limited use of components, thereby reducing complexity and cost.

In the drawings and specification, there have been disclosed preferred embodiments and examples of the invention and, although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the following claims.
