Description

Pump by using a disuse tire}

The present invention relates to a pump that is a machine for transporting a fluid through a pipe by using a pressure action, and more particularly, to construct a pump using waste tires, thereby improving wear resistance and corrosion resistance, and facilitating the manufacture or construction of the pump. The present invention relates to a pump using waste tires that can improve the performance and make the maintenance and management of the pump easier by simple replacement of parts.

In general, a pump is a machine that transports a liquid or gas fluid through a pipe by a pressure action, or pumps a fluid in a low pressure container into a high pressure container through a pipe, and not only water, but also oil, various chemicals or pulp, It is also widely used to transport special fluids such as viscose and sludge.

The basic performance of a pump is indicated by a head representing the height at which the pump can push the liquid and a flow rate representing the volume of liquid that can be pumped out in unit time. Therefore, there are many types of pumps depending on the type of head, the flow rate and the liquid to be handled.

There are reciprocating pumps, rotary (rotary) pumps, centrifugal pumps, axial pumps, friction pumps, and other pumps according to their structure. The pumps may be called feed water pumps or deep well pumps depending on the purpose. In addition, a vacuum pump is used for a machine that draws out the air or other gas in the container to create a vacuum.

That is, a reciprocating pump is a pump in which a piston or a flanger reciprocates in a cylinder, and a delivery valve and a suction valve are opened and closed alternately to pump and pump liquid. One cylinder and one set of valves are called single-acting pumps, such as domestic well pumps. In this type, pulsation of water occurs, so a combination of double-acting bumps, differential pumps, or single-acting pumps is used to average the water volume. Reciprocating pumps are suitable for large heads and small flows, and are used for hydraulic presses and boilers.

In the rotary pump, the piston acting as a part of the pump rotates to perform the piston action on the rotor. Rotors include vane pumps with sliding vanes, gear pumps with two gears engaged, and screw pumps. Compared to reciprocating pumps, the amount of discharge is less than that of reciprocating pumps, but it is widely used for water, gasoline, lubricating oil, paint, asphalt, etc., and is widely used as a hydraulic pump for automatic control.

In addition, centrifugal pumps are spiral pumps on the outside of rotating impellers, most commonly used in the industrial field. Water flows through the rotating impeller through the rotating impeller and flows out of the outer circumference. And through the spiral passage to reach the pump outlet. There are two types of turbine pumps, in which the water from the impeller passes between the guide vanes and into the casing, and the volute pump without guide vanes. The former is suitable for high lift.

In particular, when the head is large, a multistage equation is used to draw water from the guide vane of the first stage to the inlet of the second stage. It is most used among pumps used in industries such as drainage, water and sewage, mining, and chemical industry. It is suitable for distilled water, sewage, pulp mixture, gravel, coal, etc., which have been made particularly strong against wear and corrosion by improving the feather of the centrifugal pump.

And the axial pump is used when the head is low and the pumping volume is high, and the propeller-type impeller is a pump that sends water in the axial direction by rotating. It is also possible to change the installation angle of the impeller during operation so that the efficiency is not lowered even if the pumping amount is changed.

In addition, the friction pump is pumped by a rotating body that is radially grooved in the outer circumference of the disk, the fluid is used to move in close contact with the solid by the viscosity. Small household well pumps, for example shallow water wells.

In addition, a jet pump that ejects high-pressure water or steam from the nozzle to draw water together, and puts a pumping pipe into the liquid and blows compressed air at the bottom to make a mixture of liquid and air, and bubbles that pump water by reducing the average specific gravity. Pumps and the like.

On the other hand, the material of the conventional pump as described above has the disadvantages of weak wear resistance and corrosion resistance by using a cast iron material made by casting in general, heavy and expensive when used for high pressure and not easy to install In addition, it is not easy to replace the parts due to the wear of the components, and the cost of maintenance and repair of the pump is also consumed a lot and not easy to work.

Water hammer is also called water hammer, which is a pressure wave phenomenon caused by a rapid change in the motion of water in a pipeline. When a valve closes downstream of a pipeline filled with liquid, the liquid flows rapidly. The kinetic energy of the liquid is converted into pressure energy and the elastic waves reciprocate inside the tube.

The same thing happens when you rush to open a closed valve. If the liquid is completely incompressible and the wall of the pipe is rigid, the pressure when the valve is closed instantaneously is infinite, but in reality there is some compressibility to the liquid and the wall of the pipe is elastic, so when the valve is closed the wall of the pipe is slightly Although it expands, the liquid is also compressed to increase the pressure, but the pressure increase is limited.

For example, if the demand for electricity suddenly decreases or a sudden power outage occurs in an accident, the valve at the turbine inlet of the power plant is closed, causing water hammer in the steel pipe, and thus destroying the pipeline may cause a dangerous situation in the power plant. Therefore, there is an inconvenient problem of preventing the occurrence of water hammer in advance by controlling the closing speed of valves or installing safety valves by accurate calculation.

Therefore, the object of the present invention is to solve the above problems, it is possible to facilitate the manufacture and installation of the pump and to facilitate the durability and maintenance or repair, water hammer phenomenon even without using a separate device It is to provide a pump using waste tires to further improve the performance, such as to prevent and to prevent freezing.

The purpose of the present invention is to construct a pump consisting of a casing body provided with a housing and an inlet and an outlet with an impeller, using waste tires as the casing body and fixing the outlet part to one hole of the casing body The other side of the hole is fixed to the housing, the upper surface of the casing body is achieved by fixing through the discharge.

Another object of the present invention is to achieve the construction of the impeller wing, by installing the auxiliary wing consisting of a closed tire to be interchangeable on each side of the blade located in the direction of rotation.

This invention is to produce the casing body with the waste tire and to install the auxiliary wing using the waste tire on the wings of the impeller to obtain the effect of reducing the manufacturability and cost of the pump including the impeller, and improved wear resistance and corrosion resistance It is easy to replace parts, etc., so that the maintenance and repair of the pump can be made inexpensively and simply. The water hammer can be prevented by the elasticity of the casing body, and the freezing can also be prevented, so that the performance of the pump can be further improved. You can achieve your purpose.
