Description
Technical field
The present invention relates generally to fluid is fed to the pump of objective by pipeline, more particularly, relate to a kind of pump that utilizes damaged tire to make, it has high wear resistance or corrosion resistance, make pump make easily, improved pump performance, thereby and because easy replacing of parts makes pump safeguard easily.
Background technique
Known as one of ordinary skill in the art, pump is to be used for fluid, such as liquid or gas, is transported to objective by pipeline, perhaps by pipeline the liquid in the low pressure vessel is transported to machinery in the high-pressure bottle.This pump has been widely used in transporting water and special fluid, comprises oil, some medicines, paper pulp, viscose and mud.
The key property of pump is represented by lift and flow velocity.Lift is defined as the maximum height that fluid rises by pump.Flow velocity is defined as the volume of discharging fluid in the unit time.Kind according to lift, flow velocity and the fluid of handling has multiple different pump.
It can be divided into polytype according to pump structure, that is, and reciprocating pump, rotary pump, centrifugal pump, axial-flow pump, Wesco pump or the like.In addition, also it can be divided into polytype according to the purposes of pump, that is, and charging pump, deep-well pump and other.In addition, also have and to absorb air or other gas in the container so that form the vacuum pump of vacuum in the container.
The conventional reciprocating pump be designed to piston or plunger to-and-fro motion in cylinder.In cylinder in the reciprocating process, expulsion valve and suction valve alternately open or close discharging or to suck fluid, thereby fluid is promoted at piston or plunger.In traditional reciprocating pump, comprise that the pump of an independent cylinder and a pair of valve body is called as single-acting pump, for example the family expenses well pump.Under the situation of single-acting pump, the flow rate of fluid that transmits is erratic.Therefore, the amount that transmits fluid in order to keep is constant all the time, and single-acting pump and double-acting pump and/or differential action pump are used.Double-acting pump is suitable for target lift height and the little situation of target flow velocity, is used for hydraulic press brake, boiler and other equipment.
The parts that are designed to carry out piston motion of tradition rotary pump rotate.That is, the rotor of rotary pump is carried out required piston motion.This rotary pump is divided into vane pump, gear pump and screw pump.In this case, vane pump has slidably moving blade on its rotor, and does not have expulsion valve and suction valve.Gear pump has two pitch wheels.Rotary pump is littler than reciprocating pump in the variation of fluid discharge, carries various fluids but be widely used in, that is, and and water, gasoline, oiling agent, coating and pitch.In addition, rotary pump also is widely used as the hydraulic pump of control automatically.
Being designed to of conventional centrifugal pump is formed with spirality path in the outside of rotary blade, is mainly used in industrial field.When water passed through the center of impeller inflow pump, hydraulic pressure increased.Thereafter, water is discharged to the outside of impeller by spirality path, arrives delivery side of pump then.This centrifugal pump is divided into two types, that is, and and turbine pump and volute pump.Being designed to of turbine pump flow through between guide vane from the water that impeller flows out, and flows out housing then.Volute pump does not have this guide vane.In these two kinds of centrifugal pumps, the former is suitable for producing high lift.
Especially, when lift is higher, in centrifugal pump, adopt multistage guide vane.That is the inlet of the current direction second level guide vane that, from first order guide vane, flows out.Centrifugal pump is widely used in industrial field very much, comprises draining, water system, mining industry and chemical industry.Especially, improved and necessarily resistance to worn or the centrifugal pump with guide vane of anti-corrosion capacity is suitable for slurry conveyed water, sewage, mixed ore pulp solution, gravel and coal.
Axial-flow pump is used for the situation that lift is low and flow velocity is high, and its impeller that passes through the rotating screw shape is in axial transporting water.And, a kind of improved axial-flow pump has been arranged, this axial-flow pump can be in the process of its running the setting angle of conversion impeller, reduce with the running efficiency that prevents pump when the target flow velocity changes.
In addition, Wesco pump is by the impeller conveyance fluid, and it is designed to be formed with a plurality of radial grooves along the outward edge of impeller base plate.Along with the rotation of impeller, have predetermined viscosity fluid since action of centrifugal force between the groove of impeller and casing wall, move continuously, thereby fluid before being discharged from through repeatedly compression.Shallow well pump is an example of Wesco pump.Shallow well pump preferentially is used as low power family expenses well pump.
In addition, also have jet pump, air lift pump or the like.Jet pump from nozzle ejection high pressure water or steam to draw water.Air lift pump utilizes pressurized air that fluid is risen.That is, in fluid, put into a stalk and charge into pressurized air, comprise fluid and AIR MIXTURES thereby produce from the lower end of pump.At this moment, the proportion of the mixture in the stalk reduces, thereby makes fluid rise to required height.
But there is a problem in traditional pump, and promptly they are to be formed by iron casting, so abrasion-resistance and anti-corrosion capacity are low.When traditional pump was used for the high pressure pumping operation, their weight and manufacture cost will increase, and in addition, and their manufacturing also and be not easy.Because the worn part of conventional pump is replaced by relatively difficulty of new parts, thus the maintenance cost height of pump, and working efficiency is lower when changing the parts of pump.
Simultaneously, when the fluid in the fluid hose flows flip-flop, pressure surge can take place, promptly so-called water hammer.When the valve that is installed in the fluid hose downstream that is full of fluid was closed suddenly, the flow rate of fluid that flows in fluid hose can reduce suddenly and the kinetic energy of fluid can be converted into the pressure of increase, thereby fluid pipe produces water hammer, therefore produces water hammer.
When throwing open, the valve of closing also this phenomenon can take place.Suppose that incompressible ideally and wall fluid hose of fluid made by rigid material, then pressure may become infinity when valve moment closes.But, in fact, be resilient because fluid all has the wall of certain compressibility and fluid hose, thus when valve closing, can expand slightly at the effect lower wall of the pressure that increases, and fluid is compressed.But, the level that the increase of pressure only limits to be scheduled to.
For example, when the demand for electric energy reduced suddenly or unexpected power failure takes place, the valve that is installed in the turbine inlet place of power generating equipment will be closed, thereby water hammer occurs in pipe.At this moment, pipeline can be subjected to unnecessary damage, thereby power generating equipment also may be in dangerous state.Therefore, in order to prevent water hammer, must perhaps Safety valve must be installed in addition according to the accurate closing velocity that calculates control valve.
