Description

200403391 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a pump using waste tires, especially a pump made using waste tires, which can be produced by a machine made from waste tires. The casing body makes the pump easy to manufacture and can provide high abrasion resistance or high corrosion resistance, improve the performance of the pump, and easy to replace components to ensure that the pump is easy to maintain. [Prior art] As is well known to those skilled in the art, a pump is a machine that operates a fluid such as a liquid or a gas and is transmitted through a tube to a target location. The pump can also be used to operate a pump held by a low-pressure container. The fluid is transmitted to the high-pressure vessel through the tube. These pumps have been widely used to transport water and special fluids including oil, different drugs, pulp, mucus, and mud. These pumps can be classified into different types according to their structures, that is, they can be classified into reciprocating pumps, rotary pumps, centrifugal pumps, axial pumps, friction pumps, and the like. The conventional reciprocating pump system is designed with a piston or plug reciprocating in a cylinder. During the reciprocating movement of the piston or plug in the cylinder, a discharge valve and a suction valve are alternately opened or closed. Drain or inhale the fluid, thereby increasing it. In the conventional reciprocating pump, a pump system including a single cylinder and a pair of valves is called a single-acting pump, and an example of this single-acting pump is a family pump (d0 m e s t i c w e 1 1 p u m p). In the case where the single-acting system is used, the flow velocity of the fluid to be transmitted is irregular. Therefore, in order to maintain the

92334.ptd Page 7 200403391 V. Description of the invention (2) The volume is the same. The single-acting pump system is used together with a double acting pump (d ub 1 e acting pump) and / or different acting pumps. This dual-acting Lipu system is suitable for situations where the target head is high and the target flow rate is small, and it is used in hydraulic pressure, boilers, and other equipment. The conventional rotary pump system is designed to have a piston for Rotary motion elements, that is, the desired piston motion is performed by the rotor of a rotary pump. These rotary pump systems are classified into a vane pump, a gear pump, and a screw pump. In this case, the vane The pump is provided on its rotor, which has vanes that can be moved freely without a discharge valve or a suction valve, and the gear pump is provided with two gears that mesh with each other. The rotary pump system is smaller than the reciprocating pump in the case of different fluid discharges, but is widely used to transfer different types of fluids, that is, to transfer water, gasoline, lubricants, paints, and asphalt And so on. In addition, this rotary pump system is widely used as a hydraulic pump for automatic control. The conventional centrifugal pump system is designed as a spiral path formed on the outside of the rotating impeller, and is mainly used in the industrial field. When the water entering the center of the pump passes through the impeller, the pressure of the water will increase. After that, the water It is discharged to the outside of the impeller, passes through the spiral path, and then reaches the exit of the pump. • These centrifugal pumps are classified into two types, that is, they can be divided into turbo pumps and> 1¾ roll poly'pu, which 〉 1¾Wan Lipu system is designed to make water flow from the tea wheel between the guide vanes and then flow out of the casing. The scroll pump is not provided with these guide vanes. In these two types of pumps, The former is suitable for generating high heads in Puzhong.

92334.ptd Page 8 200403391 V. Description of the invention (3) Especially when the guide vane is the most widely used water system, and the chemical industry sends water containing mud and water. The cost of customary pumps for shells will increase, as it is difficult to lower the repair rate with new pumps. At the same time, when the so-called water hammer is present, and when the installation is closed, the phenomenon of the flow and the movement of the fluid is ideally impossible to make. Of course, in fact, the wall of the fluid pipe is higher than the second one. The industry leader is equipped with a pressure pump mixed with Auraura. In addition, the multi-stage guide centrifugal system of the guide vane field, the combination of the pulp with the guide wheel has a great resistance to wear and tear. In addition to the action, the conventional pump is used to replace the fluid in the fluid that generates a pressure body in the body tube. The fluid tube makes the valve and the fluid to close the system can be made. When the leaf (multi-stage head is It is used to introduce pumps for industrial, especially dirt guide wheels, and to make the process high and the components are high. When the liquid flow is in the flow image, it will be applied to the fluid pipe filled with the fluid. It also happens to be compressed, and the valve bursts out as it is because the flow is pumped by plastic, that is, the water inlet, including drainage, centrifugal pump solution, abrasive wear, and the problem is that they and the corrosion resistance Sex Their reused pumps also have worn element pumped components from the first-level centrifugal system for water, mining, and more suitable for transmission, and coal corrosion resistance. The use of iron to make it smaller, when used It is not easy to manufacture parts and manufacturing. Therefore, when the processing effect changes at this time, a surge (valve of the valve system in the downstream part of the pressure surge tube suddenly slows down), which leads to a water bond phenomenon. When opening, assuming that the wall surface of the flow system pipe is made of rigid material, the pressure can become extremely large. When the valve is compressed to a certain degree, and the valve is closed, the wall surface will

92334.pid Page 9 200403391 V. Description of the invention (4) The scales are slightly stretched, and the flow system is compressed by increased pressure. However, the increased pressure is limited to a predetermined level. For example, when the power demand suddenly decreases or a sudden power interruption occurs, the valve system installed at the turbine outlet of the power generation device is closed, and a water hammer occurs in a pipe body. At this time, the pipeline broke unexpectedly, exposing the power plant to danger. Therefore, in order to avoid the water hammer phenomenon, the closing speed of the valve must be controlled based on accurate calculations, or an additional safety valve must be installed. [Content] Lu Ji ''s invention is designed to solve the disadvantages of the conventional technology. The purpose of the invention is to provide a pump using waste tires.
