Description

In-line pump

The present invention relates to an inline pump for transporting a fluid in a pipe, and in particular, the fluid can be transported without being pressurized, and the pressurized pipe and the non-pressurized pipe are not provided separately in the fluid transfer by pressurization. It relates to an inline pump to be possible by the piping of.

In general, the groundwater is excavated from the ground to the underground rock with underground veins using excavation equipment, and then inserts an outer casing for preventing the sinking of the surface and a casing for blocking the inflow of surface contaminated water into the inside of the heart well, A submersible water motor pump is installed to raise groundwater. In other words, the submersible motor pump installed with the pumping pipe repeatedly starts and stops, pumping the groundwater in the heart to the outside and receiving it in the water tank and resending it to the required position, so that we can use the groundwater.

At this time, the submersible motor pump is disposed vertically above the submersible motor for driving the submersible pump, unlike the general pump and the motor in which the pump and the motor are arranged horizontally on the base. Accordingly, the rotational force is transmitted to each drive shaft by the coupling coupling, and the two bodies, that is, the submersible pump and the submersible motor, are integrally formed by the fixing bolt and the nut.

Submersible deep water motor pump has a plurality of pump pipes are installed in a multi-stage connection structure to be located in the deep well excavated underground, elbow pipe exposed to the top of the heart pipe is installed on the top of the pump. The supply pipe connected to the elbow pipe is provided with a hydraulic gauge, a check valve and an on-off valve.

In addition, a water pump is attached to the lower end of the pump, and an impeller is installed inside the pump to rotate at a high speed to raise water. At this time, the impeller is fixed by the rotating shaft from the underwater motor and is rotated at high speed by the action of the underwater motor and the rotating shaft. In addition, an inlet guard is mounted at the bottom of the submersible pump, and the inlet guard is provided with a plurality of inlets for inflow of water.

And an underwater motor is attached to the lower end of the inlet guard.

Referring to the operation of the submersible submersible motor pump configured as described above, after placing the submersible submersible motor pump in the heart, and applying power to the submersible motor, the rotating shaft in the underwater motor rotates and thus is fixed to the upper end of the rotating shaft. The impeller inside the pump is rotated to raise groundwater. At this time, the groundwater is introduced into the submersible motor pump through a plurality of inlets formed in the inlet guard between the submersible motor and the submersible pump. In this inflow process, it is possible to prevent the inflow of large diameter sand to some extent by the suction hole of the micro-pores.

However, the action of these inlet and inlet guards alone does not completely block the sand entering the submersible motor pump.

That is, even in a conventional submersible motor pump, a large number of sands smaller in diameter than the inlet still flow into the submersible motor pump, which causes wear of the impeller in the submersible pump or causes a failure.

In addition, in the conventional submersible submersible motor pump, sand having a larger diameter than that of the suction port is sucked on the suction port, thereby causing problems such as lowering the opening ratio of the suction port and crushing the suction port protector. More specifically, when the opening rate of the inlet is lowered, groundwater cannot be properly introduced into the submersible motor pump, thereby reducing the efficiency of the entire submersible motor pump device, and the inlet guard is also crushed by sand, which shortens the life of the device.

On the other hand, in the case of the conventional water pressure pressurized submersible motor pump, a pressure gauge is installed on the discharge side in order to cope with the abnormal pressure caused by the rapid flow rate fluctuation when water is pumped, and the water pressure is measured based on the rotational speed of the submersible motor. Coping was done in a controlled manner. However, this method has a problem that the submersible motor pump is damaged because the abnormal pressure corresponds to the time when the submersible pressure acts on the submersible motor pump for the first short time.

The present invention for solving the above problems is installed in the middle of the water pipes buried in the basement of the road and the building similarly to the conventionally used to pressurize and transfer the fluid as well as to transfer the fluid without using a pump It is an object of the present invention to provide a structure of an inline pump having an improved structure that enables a single pipe instead of a separate pipe.

It is a structural diagram of a submersible motor pump according to the prior art. It is the whole block diagram of the inline pump which concerns on this invention. It is a block diagram of the suction part of an inline pump in this invention. It is a block diagram of the bypass part of the inline pump which concerns on this invention. It is a block diagram of the DC valve part of the inline pump which concerns on this invention.

Inline pump according to an embodiment of the present invention relates to a structure including a direct current valve. Additionally relates to a structure further comprising a bypass valve.

Hereinafter, the structure and operation of the inline pump according to the present invention will be described in detail with reference to the drawings.

2 is an overall configuration diagram of an inline pump according to the present invention.

Inline pump according to the present invention is a housing 220 in which the motor and the pump is built and the suction portion 210 is the fluid is sucked, the discharge portion 250 is discharged the suction fluid, the discharge portion (not shown) shear A main valve includes a direct current valve unit 230 installed in the bypass valve unit and a bypass valve unit 240 connected to one end of the housing 220 and one end of the discharge unit 250.

However, the bypass valve unit 240 may be selectively included as necessary.

First, the suction unit 210 is a suction pipe (not shown) for the fluid flow from the external pipe, a perforated plate (not shown) to filter the foreign matter of the introduced fluid and the suction pipe (not shown) the suction pipe (drawing And a variable coupling part (not shown) for coupling the housing 220 in which the motor and the pump are installed.

The variable coupling portion (not shown) is made of a material having elasticity to allow the contraction and expansion. This makes it possible to easily solve the problem of difficulty in installation when the pipe is short or long as it is connected by a pipe of fixed length in the past.

This will be described in detail with reference to FIG. 3.

If the distance to the housing (not shown) is too long or short after connecting the suction pipe 330 to the external pipe, conventionally, the housing (not shown) is rearranged to be connected to the suction pipe 330 and the housing (not shown). The housing (not shown) should be adjusted to match the pipe, but the housing (not shown) has a very large load, and it is not easy to finely adjust it, which causes a lot of difficulties in construction and waste of time and cost.

However, in the present invention, since the material of the variable coupling part 310 is made of a shrinkable material, the variable coupling part 310 may be contracted or expanded to be connected regardless of the distance between the suction pipe 330 and the housing (not shown). Do. Accordingly, the housing (not shown) once installed does not need to be rearranged to connect the suction pipe 330.

On the other hand, the perforated plate 320 is to remove the foreign matter contained in the fluid flowing through the suction pipe.

In the submersible motor pump according to the prior art, the strainer of the strainer is used, but when foreign matter accumulates, it acts not only as a resistance to the fluid to be sucked but also extends in the direction of the housing (not shown), and is caused by the pressure of the fluid acting on the foreign matter. The strainer may be damaged and foreign substances may flow into the motor and the pump, causing a failure.

However, the punching plate 320 according to the present invention, unlike the strainer of the strainer shape, the punching tool 321 protrudes in the direction of the suction pipe 330, so that when the foreign matter accumulates on the punching plate 320, the fluid sucked into the punching plate 320 It is possible to minimize the increase in the resistance of the movement of the fluid by blocking the other tool 321 is removed from the other tool by the vortex generated while hitting the.

Accordingly, since the amount of foreign matter accumulated in the perforated plate 320 is significantly reduced compared to the conventional strainer, the possibility of breakage of the perforated plate 320 is significantly lowered, and as a result, the possibility of failure of the motor and the pump can be expected to be significantly lowered.

The housing (not shown) includes a motor and a pump therein, which is the same as the structure of a conventional submersible motor pump, so a detailed description thereof will be omitted.

Meanwhile, the present invention provides an underwater motor pump of an improved structure for removing a straight pipe used for conveying fluid without pressurization of the pump in the underwater motor pump according to the prior art, which is achieved by the following DC valve part. .

Hereinafter, a detailed configuration of the DC valve unit will be described.

5 is a configuration diagram of a direct current valve unit according to the present invention.

The DC valve unit 500 is provided between the discharge port (not shown) of the pump and the discharge pipe (not shown) connected to the external pipe as a conventional underwater motor pump composed of a pressure line and a straight line It is a device that can be used only by the line.

Specifically, at least two DC valve induction parts 561 and 562 are protruded from an end portion (not shown) of the housing, that is, a discharge port (not shown) of the pump, and the direct current is formed on an outer circumferential surface of the DC valve 520. Induction grooves (not shown) are inserted into the DC valve induction parts 561 and 562 at positions corresponding to the valve induction parts 561 and 562 so that the DC valve induction parts 561 and 562 are the induction grooves. Not included).

The reason for the configuration as described above is that the fluid flowing out of the pump outlet (not shown) has a rotational pressure by the rotational force of the pump, when such a fluid collides with the DC valve 520 the DC valve 520 is When the rotational force is applied and the repetitive rotational force is applied, the possibility of departure from the original position increases. The DC valve induction units 561 and 562 not only serve to block the rotational force but also the DC valve 520 is opened. When returning to the closed position also serves to guide the DC valve 520 to be in the correct position.

The direct current valve 520 opens or closes the discharge port of the pump by the pressure of the fluid. When the direct current valve 520 is opened, the direct current valve 520 is opened by the pressure of the fluid.

The DC valve elastic control unit 530 is sufficient to have elasticity, and one end of the DC valve elastic control unit 530 is inserted into the first mounting unit 540 formed at the end surface of the one end of the DC discharge unit (not shown) in the discharge tube direction. The other end is inserted into the second mounting portion 550 formed in the upper portion of the DC valve to a sufficient depth.

Meanwhile, the elasticity of the DC valve elastic control unit 530 should be such that the DC valve 520 opens the discharge port by the pressure of the fluid that is not pressurized by the pump, and the original position when the transfer of the fluid is stopped. The pressure enough to recover the direct current valve 520 is sufficient.

The DC valve elastic control unit 530 may be adjusted by the adjusting means provided in the first mounting unit 540, and such a configuration is commonly known, and thus the detailed description thereof will be omitted.

In addition, a DC valve buffer 510 is further provided at a lower surface of the DC valve 520 that is connected to the DC valve 520 to restore the DC valve 520 to its original position by the pressure of the DC valve elastic control unit 530. In this case, the DC valve 520 functions to cushion the pump so that it does not directly collide with the outlet end surface of the pump. On the other hand, the DC valve 520 and the DC valve buffer 510 is a screw groove (not shown) is formed in the center thereof is coupled by the DC valve coupling portion 580, the DC valve coupling portion 580 is the It may be combined with the second mounting portion 550. Accordingly, even if a part of the DC valve part 500 is damaged, only the damaged part can be replaced without replacing the whole part.

The DC valve unit 500 should be coupled to the pump discharge port (not shown) and the screw groove (not shown) formed outside the housing (not shown) and the outside of the DC valve unit 500 for this purpose. A through hole corresponding to the screw groove (not shown) is formed on one side, and the through hole and the screw groove (not shown) may be screwed together.

The inline pump according to another embodiment of the present invention does not include a DC valve, and relates to a structure including only a bypass valve. Hereinafter, a detailed configuration of the bypass valve unit will be described.

4 is a configuration diagram of the bypass valve unit 400 according to the present invention.

The bypass valve unit 400 includes a bypass casing 470 having integral components provided therein.

A bypass suction pipe 463 and a bypass suction port 461 are formed at one side of the bypass casing 470 and are coupled to a housing discharge port (not shown) formed at one side of a housing (not shown). Meanwhile, dividing valves 451 and 452 may be further provided between the housing discharge port (not shown) and the bypass suction port 461, and may be further provided between the discharge tube suction port (not shown) and the bypass discharge port 462. The second dilution valve 452 may be further provided.

The dilution valves 451 and 452 are for blocking the fluid flowing into the bypass valve 400 when the bypass valve 400 is repaired, and the first dilution valve 451 is introduced from the housing side. The fluid to be blocked is blocked, and the second dilution valve 452 blocks the fluid flowing from the discharge pipe side. However, under normal circumstances, the first and second dividing valves 451 and 452 are left open.

The fluid introduced through the bypass suction pipe 463 is discharged to the discharge pipe through the bypass discharge pipe 464 through the through hole inside the bypass casing 470.

In the bypass casing 470, a bypass support part 412 is formed in whole or in part along a circumferential surface on one side of the inner circumferential surface thereof. The bypass support 412 is for supporting the bypass valve 410 to be described below.

The bypass valve 410 is mounted on one side of the bypass support 412 in the discharge tube direction. In addition, a bypass valve buffer 411 may be further provided between the bypass valve 410 and the bypass support 412.

In addition, a first bypass control pressurizing unit 425 is further provided on one side of the bypass valve 410 in the bypass suction pipe direction, and a first bypass valve connecting unit 421 is provided at the first bypass control pressurizing unit 425. ) Is combined. The first bypass valve connection part 421 is inserted into and coupled to the first bypass valve connection guide part 423 provided at one side of the bypass casing 470.

The first bypass valve connection part 421 extends through the first bypass valve connection guide part 423 and the bypass casing 470, and has a first bypass control handle at a portion extending through the hole. 422 may be further provided.

Looking at the operation of the bypass valve 410 according to the configuration as described above, the bypass valve 410 receives the pressure from the fluid by the pressure of the fluid flowing from the housing discharge port and thus the bypass valve 410 ) Moves in the discharge tube direction. At this time, the first bypass valve connecting portion 421 is also moved, but since the first bypass valve connecting portion 421 is guided by the first bypass valve connecting guide portion 423, the bypass valve 410 is the center. Is moved in the axial direction.

On the other hand, when there is no fluid flowing from the housing discharge port, the fluid remaining in the discharge pipe flows back to the bypass valve unit 400, wherein the bypass valve 410 is a suction pipe by the pressure of the flow back flow Direction, and when the bypass valve 410 is moved to the bypass support 412 to block the flow of the fluid.

The bypass valve buffer 411 may be made of a material having elasticity to prevent direct collision with the bypass support 412 when the bypass valve 410 is moved in the direction in which the bypass valve 410 is blocked as described above. .

Meanwhile, in the above configuration, the bypass valve 410 is moved only by the pressure of the fluid, so that some fluid may be flowed back to the housing (not shown) during the back flow, and the fluid thus flowed back is the housing (not shown). Internally, the waste water adversely affects the motor and the pump. In order to improve this, a configuration for automatically returning the bypass valve 410 to a position where the inflow of fluid from the suction pipe is stopped is added.

Specifically, the bypass valve 410 is achieved by the bypass valve pressure control unit 440 which acts in the opposite direction to open the elastic force, the center of the bypass valve 410 and the bypass valve buffer 411 is formed The second bypass valve connecting portion 432 is fitted into the through portion (not shown) and coupled to the second bypass valve connecting guide portion 433 formed on the end surface of one side of the discharge casing side of the bypass casing 470. ) Is inserted along the outer circumferential surface of the second bypass valve connecting portion 432 and one side is supported by the second bypass valve connecting guide portion 433, and the other side is supported by the bypass valve 410. Being further includes a bypass valve pressure control unit 440.

The second bypass valve connecting portion 432 extends through the second bypass valve connecting guide portion 433 and the bypass casing 470, and a second bypass control handle (H2) is formed in a portion extending through the passing through. 431 may be further provided.

The operation of the bypass valve unit 400 according to the above configuration will be described below.

In the state where the bypass valve 410 is opened by the pressure of the fluid, the bypass valve pressure controller 440 is contracted by the pressure of the fluid. At this time, the bypass valve pressure controller 440 is formed of an elastic body. There is a restoring force as much as the contracted position when the contraction, the pressure and restoring force of the fluid is in equilibrium, so the bypass valve 410 is in a stop open state at that position.

When the inflow of the fluid is stopped in this state, the equilibrium of the pressure and the restoring force of the fluid is broken and there is no inflow of the fluid, so only the restoring force acts, and the bypass valve 410 is in the closed state by the restoring force.

The restoring force can be adjusted as needed and this is achieved by the first bypass control handle 422. In detail, when the first bypass control handle 422 is rotated or pushed to one side, the first bypass valve connection part 421 and the first bypass valve connection part connected to the first bypass control handle 422 ( The first bypass control pressurizing unit 425 connected to the 421 is moved, which causes the first bypass valve connecting unit 421 to move, and the bypass valve pressure controller 440 is configured to move the first bypass. Since it is connected to the valve connecting portion 421, the connection point of the bypass valve pressure control unit 440 and the first bypass valve connecting portion 421 is moved. Accordingly, the initial contraction / extension state of the bypass valve pressure controller 440 is changed so that the threshold value at which the bypass valve 410 starts to move is changed by the pressure of the fluid.

On the other hand, a situation may occur in which the fluid is forced to flow back from the discharge tube to the housing side. For example, when the pressure in the discharge tube is greater than or equal to the set value, the fluid in the discharge tube must be recovered.

The present invention includes a configuration such that the bypass valve 410 is forcibly positioned in order to force the fluid to flow back.

This operation is accomplished by the second bypass control handle 431 and the second bypass valve connection 432.

In detail, when the bypass valve 410 needs to be forcibly opened, moving the second bypass control handle 431 may cause the second bypass valve connection part 432 connected to the second bypass control handle. Is moved correspondingly, and since the second bypass valve connection part 432 is coupled to the bypass valve 410, the bypass valve 410 is like the second bypass valve connection part 432. It moves and stays open.

In the description of the embodiment of the present invention, it is described that the DC valve portion and the bypass valve portion are formed separately, but the present invention may be used in combination with the DC valve portion and the bypass valve portion.

Specifically, the component for automatic restoration and the component for forced opening may be removed and coupled to the DC valve unit and the bypass valve unit, and the DC valve unit and the bypass valve unit may be combined by adding only a configuration for automatic restoration. Alternatively, the DC valve unit and the bypass valve unit may be combined to include both a configuration for automatic restoration and forced opening.

It is apparent that the combination of components for this purpose can be inferred by the configuration and operation of the first and second embodiments.
