Description

[Detailed description of the invention] PUMP FOR SUCH PUMP AND USE OF SUCH PUMP The present invention provides at least 2i! The present invention relates to a multichamber pump having two chambers. Furthermore, the present invention The invention relates to valves for pumps such as and the use of said pumps.

squeezed tube pumps, e.g. mounted on a rotating wheel A squeeze roller allows the flexible hose to be divided into multiple chambers within its bong section. What is classified is known. The squeeze roller is placed on an underlying solid surface, e.g. Press the hose against the plate. Each chamber is for the rolling operation of the squeeze O-ra. The pump is filled with pumping medium which is sucked and discharged by the pump. These pumps are for example When a mixture of liquid and gas is the pumping medium, it is often inoperable. He is known to fall into Noh. Too much gas can be pumped ineffectively. and damage the flexible hose if the pumping medium also contains solids. There is a risk that

The object of the invention is to include any desired alternation of liquid and gas phases with reasonable efficiency. The first objective is to create a pump that can suck and pump a medium having a mixing ratio. The port The pump must be able to pump both the pure gas phase and the liquid phase. Another aim is to create a valve particularly suitable for such pumps.

A further object of the invention is to provide a particularly advantageous pump according to the invention. It is to indicate other different uses.

According to the invention, there is provided a multichamber pump having at least two chambers with variable displacement. Therefore, the air is connected in series in the direction in which the pumping medium is pumped and discharged, and each of said empty valves has at least one inlet valve and/or at least one outlet valve. It is an outlet valve that has lower resistance in the pump suction and discharge direction than in the opposite direction. and said seedling has at least one of them. having means for permitting an increase or decrease in volume and increasing the volume of at least one chamber; Alternatively, it is provided with drive and control means for reducing. According to the invention The valve is characterized by the features indicated in the characterizing part of independent claim 22. . According to the invention, the use of the present row seedling pump is defined in independent claims 23 and 24. It is characterized by the features shown in the feature section of the term.

The dependent claims relate to advantageous embodiments of the invention.

The multichamber pump according to the invention can be used to control any of the individual liquid and gas phase components of the pumping medium. Easily pump single-phase and multi-phase mixtures through exchange. However, two-phase simply It is also possible to pump one side alone with appropriate efficiency. 2 phase is that Selecting a valve that produces vigorous mixing of these as the mixture flows through it separation is prevented by Arranging multiple chambers directly adjacent to each other This contributes to the compact construction and probably only one valve bottom direct Actuation and individual valves as discharge valve for one chamber and suction valve for the next chamber Contributes to a dual function. A flexible hollow wall, made from a flexible material such as an elastomer. The use of curved bellows contributes to the simplicity of the design. such bellows alone For slightly lower compressive strengths, use a corset-type pressure jacket or pressure vessel can be substantially increased by

Most types of systems are pumps, e.g. hydraulic pistons, especially annular hydraulic pistons. synchronous or asynchronous motors in the form of linear motors, e.g. , longitudinal motion spindle drive device, rack and pinion drive device, longitudinal motion clutch It can be used to drive an attached drive device or the like.

Apart from allowing quieter braking of these mechanical parts, e.g. Installing the spring member as a conversion dog for the scope-shaped tube This allows energy for the traveling process to be recovered.

Configuring the pump as a mechanical vibrator for operation at a resonant frequency is This is particularly useful and advantageous from an energy consumption standpoint.

As a spring element to compensate for pressure pulsations in the system, e.g. , the amount of pumping of a mixture of liquid and gas, and the compartment chamber as a gas chamber filled with gas. may be provided. The compartment can be assembled onto the valve. But alternatively, the valve is retracted can also serve as a body and/or multiple independent pumps are bodies and pump substances. dead volume (dead volume is the volume of pumping medium remaining in the pumping chamber at the end of the pumping phase) ), thereby improving pump efficiency.

To improve pump operation and operation when multiphase pumping m* is used, e.g. For example, keeping the ratio of gas to liquid components within certain limits or The decision level, i.e. the level obtained using the recycling device, is lower than the Unforgiveness can be useful. In the case of such recirculation equipment, the bottle The pumping medium (gas and/or liquid) is supplied from subsequent stages of the pump, preferably to the final stage. from one stage to the next, preferably the first stage, to obtain or maintain the desired ratio of phases. It is replenished along the return line in order to Also, in order to obtain the desired ratio of the various phases, The centrifugal separator is equipped with an impeller before the discharge valve of an individual stage or multiple stages. It may also be envisaged to arrange a plate or other liquid separation device.

A multichamber pump can be assembled from a series of identical stages connected in series, and about 10 Approximately 30 bar per stage, i.e. fB full, and in the case of a telescopic chamber configuration It is a simple matter to create a pressure increase of more than bar.

Therefore, pressure increases of 50-100 bar can easily be achieved using such pumps. It can be done.

The movement of individual seedlings, or rather the bottom of the chamber, is as much as possible with pumping action 3! continuous It is adjusted as follows. Typically, the number of steps N is 360° as the phase difference power or its multiples. It is equal to the value divided by . For example, the outstanding bombing characteristics Three stages connected in series, operating with a 120° phase shift and in input order can already be obtained using one with symmetrical filling and pumping phases. .

For example, in push-pull operation (180° phase difference), individual air or valve bottom The movement of the parts is continuous so that one air is always in the pumping phase alternately and the adjacent The chamber is adjusted so that it is in the filling phase.

It is not necessary that the filling phase and the pumping phase be of the same length. Instead , the pumping or compression phase is longer than the return or filling phase in the input order. It is advantageous to reduce the The valve bottom follows the trapezoidal motion curve, follows the sinusoidal curve, or may be driven according to other fixed motion curves.

Interaction of multiple stage motion sequences can be accomplished in a variety of ways. Main points means that successive stages can be created without unnecessarily consuming energy. (qualities for dynamic flow, i.e., the invariant law of flow rate, i.e., through the control surface) The difference between the mass flowing out during the predetermined interval and the mass flowing in during the predetermined interval is 1Jtll must be equal to the mass lost in one plane). should be adjusted and configured accordingly.

For example, in the case of liquid-only operation, the motion may be subject to strict timing common to all stages. It is advantageous if the timing cycle is followed. In the case of multiphase mixtures, pumping The larger the compressible component in the programming medium, the more important synchrony becomes. It disappears. This type of system is used when the pumping medium has a special composition. , can be constructed to automatically adapt (self-adaptive) to the pumping optimum conditions.

For example, operating each pump stage at a given power or pumping it to a given maximum. by designing for pressure (pressure increment between entering and exiting the stage). It is possible to achieve self-adaptation. This prevents individual stages from being overloaded. and distribute the drive output evenly between the stages.

The output of the drive of the individual stages of the pump can be adapted in various ways. electric motor is current It may be equipped with a regulator and thus a pressure and/or power regulator. For example, hydraulic The pump can be fed from a constant pressure source so that the stages of the pump are adjust themselves.

Their large throughput capacity in the forward direction and low flow resistance in the reverse direction as well Their excellent blocking resistance is due to their simple structure as well as high reliability. Tower or step valves are particularly useful for pumps according to the invention, as shown in FIG. Melt.

Good mixing of the pumping medium during pumping action makes such pumps Suitable as single flow forest material exchange am, single flow mixing device and/or gas treatment VR1j I'm going to do it.

In this context the term single flow flows in the same direction (as opposed to counterflow mixer) It means that. A pump according to the invention used solely as a mixing device may simply: It may have an output pressure slightly higher than the input pressure.

Another way to achieve self-adaptation is to have some of the valve bases synchronously, but not synchronously. It is meant to operate freely. That is, the movements of multiple valve bottoms no longer have a common prediction. I11m is not determined by the decision timing cycle; instead, the valve bottom is At the end of their stroke, the direction of their movement is automatically controlled by a limit switch. to reverse it.

If only liquid is pumped, the stages will still be the same due to the incompressibility of the liquid column. Continues to operate for a period of time. However, as the compressible component in the pumping medium increases, Therefore, the synchrony breaks down, and as a result, the stages reduce themselves to the requirements of the continuity equation. In response, inter alia, to the composition of the multiphase pumping mixture, it is practically ideally suited. It can be adapted.

In the case of hydraulically operated pumps, the individual stages themselves are configured as differential cylinders, This eliminates the need for a separate drive cylinder.

For this purpose, each stage can be integrated into a pressure vessel. Bellows or telescope type The diameter of the tube jacket is smaller on the suction side of the stage than on the discharge side of the stage. stomach.

As a result of the difference in diameter (difference in cross section), the increase or decrease in pressure in the pressure vessel is caused by the moving parts of the stage. to generate an axial force, thereby driving the movable part.

The advantage of such a design, especially in the case of telescopic embodiments, is that the pressure can be maintained higher than that in the pumping medium itself.

This prevents leakage to the outside. Internal wetting may occur if the pressure or driving fluid is also damping medium or can be ignored if chosen to be compatible with it.

The bead, made of highly flexible material such as an elastomer, can be It has the advantage that a change in the rate, for example 100%, can be tolerated. This is the dead volume allow to be kept within limits. Also, it has a relatively short assembly length This allows large stroke slow-acting pumps to be produced. These flexible bellows The disadvantage is their low compression resistance, e.g. only 5 bar, and as a result The number of stages increases when high pressures have to be achieved.

On the other hand, metal bellows withstand pressure much better and also e.g. suitable for the pressure of the wall. However, in long-term operation, they , ie the pumping movement, allows only a change of, for example, 10% in odor. The valve bottom is When arranged as usual (valve base located in the middle of the bellows), this is extremely This results in a large dead volume. This drawback causes the valve surface to be asymmetrical (at the end of the bellows) partially corrected by positioning the valve face).

Pumps in which the valve base is actuated directly, e.g. by a rigid mechanical link Chambers have the disadvantage that the linear motor is only under maximum load during the dispensing stroke. difference Furthermore, direct actuation of the valve base requires relatively large forces and low speeds.

These two factors make linear motors large, heavy, inefficient, and inappropriate to use. encourage the use of Linear motors have smaller power and higher Better if designed for speed and loaded maximally in both directions of motion It can be made lighter and more compact while achieving efficiency. This is also If the oscillating motion of the linear motor is transmitted to the valve base by suitable transmission means. It is possible. The nature of this transmission means is such that it is made available by a linear motor. a rapid but less forceful movement than required by the valve base. transforms into a more powerful motion, and both forward and backward motion of the linear motor is pumped. It must be such that it can be used for operational purposes.

Such transmission means are e.g. rope-belt or steel-belt lines, racks, etc. It may be realized mechanically or otherwise hydraulically.

The invention will now be described in more detail with reference to the accompanying drawings, which show examples of embodiments of the invention and details thereof. It will be explained in detail.

There is a bellows 81 made from a material made of Chinese material located between the bottom of the valve. be done. Due to the compliance of this valve, the pressure inside the pressure vessel is reduced to the bottom of the valve. It is always the same as the simple one. This is because the flexible bellows is not deformed by pressure, and This means that the metal bellows is subjected to only a single stage of pressure. single Highly flexible bellows may be used because the internal and external pressure conditions are the same. At the same time advantageous assembly lengths can be obtained. The length of the steps is low to high flexibility. compared to stages in which the bellows 81 is replaced by one or more metal bellows. , is almost halved. The drive of the valve base 85,86 is not shown here, but , can be of any type. Finally, Bose 81 can even be omitted. possible, but it would make the dead volume somewhat larger.
