Definitions

  • the present invention relates generally to pumps which are operated to feed a fluid to a target place through a pipe, and more particularly, to a pump which is manufactured using a waste tire, capable of providing high abrasion- resistance or corrosion-resistance, allowing the pump to be easily manufactured, enhancing the performance of the pump, and ensuring easy maintenance of the pump due to easy replacement of components.
  • pumps are machines which are operated to transfer a fluid, such as liquid or gas, to a target place through a pipe, or are operated to send a fluid contained in a low-pressure container to a high- pressure container through a pipe.
  • a fluid such as liquid or gas
  • Such pumps have been widely used for transferring water as well as special fluids, including oil, several medicines, pulp, viscose, and sludge.
  • a basic performance of a pump is indicated by a head and a flow rate.
  • the head is defined as a maximum height of a fluid raised by the pump.
  • the flow rate is defined as a volume of a fluid discharged per a unit time.
  • the pumps are classified into several types according to their structures, that is, reciprocating pumps, rotary pumps, centrifugal pumps, axial pumps, friction pumps, etc. Further, the pumps are classified into several types according to their purposes, that is, feed pumps, deep well pumps, and others. In addition, there is a vacuum pump which sucks air or other gases from a container to form a vacuum in the container.
  • the conventional reciprocating pumps are designed such that a piston or plunger reciprocates in a cylinder. During a reciprocation of the piston or plunger in the cylinder, a discharging valve and a sucking valve are alternately opened or closed to discharge or suck a fluid, thus raising the fluid.
  • a pump comprising a single cylinder and a pair of valves is called by a single acting pump, and an example thereof is a domestic well pump.
  • the single acting pump In the case of the single acting pump, the flow rate of a transferred fluid is irregular. Thus, in order to keep the amount of the transferred fluid uniform, the single acting pump is used in cooperation with a double acting pump and/or a differential acting pump.
  • the double acting pump is suitable for a case where a target head is high and a target flow rate is small, and is used in a hydraulic press, a boiler and other equipment.
  • the conventional rotary pumps are designed such that a component performing a piston movement is rotated. That is, a rotor of the rotary pump performs a desired piston movement.
  • Such rotary pumps are classified into vane pumps, gear pumps, and screw pumps.
  • the vane pump is provided on its rotor with a slidably moving vane without having a discharging valve or a sucking valve.
  • the gear pump is provided with two gears which engage with each other.
  • the rotary pump is smaller, in the variation of the discharging amount of a fluid, than the reciprocating pump, but is widely used for transferring various kinds of fluids, that is, water, gasoline, lubricant, paints, and asphalt.
  • the rotary pump is widely used as an automatically controlled hydraulic pump.
  • the conventional centrifugal pumps are designed such that a spiral path is formed outside a rotating impeller, and are mainly used in industrial fields. While water entering a center of the pump passes the impeller, the pressure of water is increased. Thereafter, water is discharged to the outside of the impeller, passes the spiral path, and then arrives at an outlet of the pump.
  • Such centrifugal pumps are classified into two types, that is, turbine pumps and volute pumps.
  • the turbine pump is designed such that water flowing from the impeller passes between guide vanes, and then flows out of a casing.
  • the volute pump is not provided with such a guide vane. Of the two types, the former is suitable for generating a high head.
  • a multi-stage guide vane is used in the centrifugal pump. That is, water flowing from the guide vane of a first stage is led to an inlet of the guide vane of a second stage.
  • the centrifugal pump is most widely used in industrial fields, including drainage, water supply, mines and chemical industries.
  • the centrifugal pump with a guide vane improved to have considerable resistance to abrasion or corrosion is suitable for transferring water with sludge, sewage, pulp-mixed solution, gravel, and coal.
  • the axial pump is used in the case where a head is low and a flow rate is high, and transfers water in an axial direction by rotating a propeller-shaped impeller. Further, there has been developed an axial pump which is capable of changing the installation angle of the impeller during the operation of the pump, in order to prevent the operational efficiency of the pump from being reduced although the target flow rate is changed. Further, the friction pump transfers fluid by an impeller which is designed such that a plurality of radial recesses are formed along a peripheral edge of a base plate of the impeller.
  • a shallow well pump is an example of the friction pump.
  • the shallow well pump is preferably used as a small-capacity domestic well pump.
  • the jet pump jets high-pressure water or steam from a nozzle so as to suck water.
  • the air lift pump raises a fluid using compressed air. That is, a lift pipe is put into a fluid and compressed air flows into the pump at its lower end, so that a mixture consisting of the fluid and air is produced. At this time, the specific weight of the mixture inside the lift pipe is reduced, so the fluid is raised to a desired height.
  • the conventional pumps have a problem that they are made of cast iron using castings, so abrasion-resistance and corrosion-resistance are low.
  • the conventional pumps are used for high-pressure pumping action, their weight and manufacturing cost are increased, and besides, their manufacture is not easy. Since it is difficult to replace worn components of the conventional pumps with new ones, the maintenance cost of the pumps is high, and the working efficiency while replacing the components of the pumps is low.
  • a valve installed at an inlet of a turbine of a power plant is closed, so a water hammer occurs in a pipe.
  • a pipe line is undesirably broken, so the power plant may be exposed to danger.
  • the closing speed of the valve must be controlled on the basis of an accurate calculation, or a safety valve must be additionally installed.
  • an object of the present invention is to provide a pump using a waste tire, which is easy to manufacture, has a high durability, and ensures easy maintenance, and which prevents a water hammer from occurring, in addition to the prevention of rupture of the pump due to cold, without using an additional device, thus enhancing the performance of the pump.
  • the present invention provides a pump using a waste tire, including a housing provided with an impeller and a casing main body having an inlet port and an outlet port, wherein the casing main body is made of a waste tire, and an inlet port unit is installed at a first opening which is provided at a side of the waste tire, thus functioning as the inlet port of the casing main body, and the housing is installed at a second opening provided at another side of the waste tire opposite to the first opening, and an outlet port unit is installed at a predetermined portion of the waste tire to function as the outlet port of the casing main body.
  • Another object of the present invention is to provide a pump using a waste tire, which is designed such that a sub-vane made of a waste tire is removably mounted to a surface of a main vane of the impeller rotating to force a fluid in a desired direction.
  • the present invention provides a pump, which is designed such that a casing main body is made of a waste tire and a sub-vane made of a waste tire is removably mounted to a main vane of an impeller, thus allowing the pump to be easily manufactured and reducing the manufacturing cost of the pump, and providing high abrasion-resistance and corrosion-resistance, and ensuring easy maintenance of the pump and reducing its maintenance cost due to easy replacement of components, and which is designed such that the casing main body has elasticity, thus preventing a water hammer from occurring and preventing the pump from being frozen to rupture, therefore enhancing the performance of the pump.

  • the liners 210 and 220 are used for easily replacing the waste tire of the casing main body 110 with another waste tire.
  • the inlet port unit 130 is fastened to the liner 210 by means of fastening pieces 170, so that the fastening pieces 170 stably hold the inlet port unit 130 while preventing the inlet port unit 130 from downwardly drooping.
