Description

Chemical pump structure capable of preventing liquid molecules conveyed in pump from leaking and with lift determined by motor

Technical Field

The invention relates to a chemical pump structure which does not leak liquid molecules conveyed in a pump and has a lift determined by a motor.

Background

Various liquid pumps with different specifications emerge endlessly, and the defects are as follows: the liquid pump in the prior art adopts various sealing structures, mainly sealing rings with various specifications made of polymer soft materials and smooth metal surface with roughness for pressing, but the so-called 'sealing' in the prior art can only be regarded as a 'semi-sealing' measure which can absolutely not stop fluid molecules such as common air molecules and water molecules from passing through, otherwise, the automobile tire and the bicycle tire can never be inflated. -cutting and recording: only the undetachable metal weld seam can stop the passage of the fluid molecules.

The most used possibility in the chemical field is the alkali pump, which is taken as an example:

the alkali pump is mainly an apparatus used on land, the required lift is generally high or very high, but due to the structural restriction of the prior art of the conventional alkali pump, the lift cannot be designed very high, otherwise, the feedback force of a certain proportion of the overhigh lift output pressure conference directly influences the normal work of a driving motor forming the alkali pump, the sealing force to the rotating shaft of the motor is enhanced, but the alkali pump still leaves the ideal degree to a very far extent despite great technical cost, and therefore, the alkali pump cannot adapt to the requirement of the sealing degree to the rotating shaft of the motor without reducing the lift of the alkali pump intentionally.

Furthermore, the problem of leakage prevention of the alkali pump is a big problem that cannot be ignored, and it can be said that the prior art of the alkali pump has not yet reached the sealing strength of the liquid molecules transported inside without leakage that can be reached when the alkali pump is not leaked outside, although: the alkali pump is not an extremely expensive or highly toxic liquid, however, it is always a welcome matter for chemical pumps mainly based on alkali pumps to prevent the internal leakage of the chemical pumps.

Disclosure of Invention

The purpose of the invention is as follows: the two problems of the liquid molecules conveyed in the pump without leakage and the pump lift determined by the motor are solved.

The key points of the invention are as follows: the invention is realized by starting from a completely novel design scheme

Compared with the prior art, the invention has the characteristics that: on the premise of solving the content of the key points, the characteristics of simplest structure, easiest manufacture and highest cost performance can be realized.

Detailed Description

In order to achieve the above object of the present invention, the following technical solutions are adopted:

the invention is composed of a motor part as a driver and a liquid pump (9) part as an executor;

the method is characterized in that:

firstly, the rotating direction of the blades gamma which are driven by the rotating shaft 6 of the motor extending into the liquid pump 9 to drive the liquid to flow in the integral structure causes the driven liquid to flow away from the motor;

the upper side of the driving vane gamma is distributed with the path liquid entering from the outside, and the lower side of the driving vane gamma is distributed with the path liquid leaving from the pump.

Secondly, at least the rotor 2 is surrounded by a metal sealing isolation cavity 5 in a three-dimensional mode, and a motor shaft seal 7 is arranged at the lowest conical bottom of the metal sealing isolation cavity 5;

all splicing gaps related to the metal sealing isolation cavity 5 are connected through a non-detachable welding process.

A liquid pump 9 containing a driving blade gamma is surrounded by a metal sealing structure 10 in a three-dimensional manner, and the liquid pump 9 is provided with a liquid inlet pipe interface 11 and a liquid outlet pipe interface 8;

all the splicing seams involved in the metal sealing structure 10 are connected by a non-detachable welding process.

Fourthly, the integral connection of the metal sealing isolation cavity 5 and the metal sealing structure 10 is also realized through the welding process of the non-detachable welding ring part D.

And fifthly, the design scheme of the chemical pump structure is also suitable for the design scheme of a non-chemical pump, namely the technical requirement of the structural design scheme of a common water pump. The possible coverage of the invention extends to all water pump apparatus.

The key points of the core can be further commented according to the description:

the term "a" emphasizes that: the rotation direction of the driving vane gamma causes the flowing direction of the liquid in the pump to be from top to bottom as illustrated in fig. 1, and the high pressure generated by the driving vane gamma is far away from the location of the motor, therefore, the generated high pressure can not be fed back to the inside of the motor through the gap of the position of the motor shaft seal 7 to affect the normal operation of the motor as in the prior art. -as follows: the pressure of the wind above the propeller is always within a range slightly less than one atmosphere, regardless of the magnitude of the downward wind force of the helicopter when the propeller is rotating. This slight pressure change is easily coped with.

The second money emphasizes that: the motor of the invention belongs to a fully-sealed entity, and no second gap higher than the gap exists except that a movable fit gap which is formed at the bottom of the motor and is caused by a motor rotating shaft 6 through which fluid water molecules and air molecules can pass is arranged. Only the inlet and outlet of the two gaps of the lower part and the upper part can form a channel for allowing the fluid molecules to pass through under the driving of the pressure of the external water body. Obviously: the metal sealed isolation cavity 5 is a full-sealed body which can not form a fluid molecular channel, namely, an aspect condition is created for the matters of stopping the liquid molecules of the invention from being leaked to the outside absolutely, and the like.

The three money emphasizes that: although in the metal seal 10 (housing of the liquid pump 9) there is only a gap through which the top motor shaft 6 passes, there is no gap in the second housing, and it is obvious that: similarly, the metal sealing structure 10 is also a fully sealed entity that does not form a fluid molecular channel, i.e. an aspect is created for the purpose of stopping the liquid molecules of the present invention from leaking to the outside.

The four money emphasizes that: the joining of the two above-mentioned bodies, again by means of a single welded seam, is evident: the formed solid structure is a brand-new full-sealed solid structure. This also creates an aspect in the prevention of the possibility of the liquid molecules of the invention leaking to the outside absolutely not present.

Obviously, the specific implementation steps can be carried out according to the following methods:

the first step is as follows: taking the content of the above "one" money first, the remaining money is not enabled, i.e. implemented as in the case of prior art pumps, it will be seen that:

the inventive alkaline pump's pull-out is not restricted as in the prior art, i.e., the important problem in this respect is completely solved, but the problem of preventing leakage of liquid molecules from the pathway pump to the outside is still to be further solved.

The second step is that: on the basis of the content of the item "one", the content of the items "two" to "four" is respectively taken, which can only obtain partial benefits for the leakage prevention problem of the liquid molecules conveyed by the alkali pump, and can absolutely ensure that the leakage prevention device only takes the whole content of the items "two" to "four" again:

it is also an important purpose to not leak the liquid molecules transported in the pump.

Finally, in accordance with the above-mentioned requirement, it should be noted that the sheath of the power line used in the prior art is made of a polymer-based rubber-plastic material, and the material itself cannot stop the penetration of air molecules, so that it should be noted during the "drilling and threading" process of the power line: it cannot be made a "non-leaking liquid molecule transported in the pump" tripartite stone.

If: as in the prior art, the technical means of "drilling and threading" is implemented by placing the power line on the top of the metal sealed isolation cavity 5 of the present invention, so that the external liquid molecules conveyed by the lower liquid pump 9 can pass through the motor shaft 6 after being gasified under the influence of the high temperature of the motor during the operation process:

firstly, after the shaft hole position of the top of a lower liquid pump 9, the lower liquid pump goes up to pass through a shaft seal position 7 to enter a metal seal isolation cavity 5 of a motor, and finally, the lower liquid pump enters from the top of the lower liquid pump through a 'drilling and threading' to form a sheath which is made of rubber and plastic high polymer materials and allows gas molecules to pass through a power line, so that the fluid molecule channel is formed, and the gas molecules are leaked to the outside.

The improvement proposed here for this purpose is:

the power line 4 should be connected to the motor stator 1 after penetrating from the lowest conical bottom (motor shaft seal position 7) of the metal sealed isolation cavity 5 constituting the present invention, and it must be noted that:

the lead wire section of the transition power line 4 (the section which does not enter the interior of the motor) which passes through the space section of the tapered outer bottom of the metal sealed isolation chamber 5 must be covered with a circle of additional metal sheath Q of the power line, and the front and rear ends of the metal sheath Q are positioned by welding at a position slightly above the welding circle section D illustrated in fig. 1 and the tapered outer bottom of the metal sealed isolation chamber 5.

The final penetration of the electric line Q into the metallic sealed insulating chamber 5 constituting the present invention is not as simple as the prior art, but can always be properly solved according to its principle of "stopping the passage of fluid molecules".

Because the whole structure of the invention belongs to the entity of the totally enclosed type which can not be dismantled forever, its one-time service life is totally dependent on the one-time service life of the traction motor used in the invention.

It is said that:

the one-time service life of a non-detachable full-sealed type electric refrigerating compressor used in a domestic refrigerator is generally 10 to 20 years, and once damaged, the whole compressor is generally replaced. The service life of the similar compressor produced in Japan can reach more than 30 years generally.
