Water pump 2 of the present utility model owing to be in work under the muddy water, just has higher requirement to performances such as it seal, lubricates.This pressurising immersible pump and existing immersible pump structure are basic identical, and different is to increase to be provided with a rotation axis seal 68 on motor room bearing block 63B position, with 2 rotation axis seals, the 68 common formation 3 moving axis sealings 68 in the rotation axis seal chamber 71.Oil resistant balloon 70 is eliminated oil temperature and is changed the volumetric expansion that causes.Employing has solved water and has entered the problem of wherein damaging water pump 2 mode of water pump 2 pressurising work, has prolonged maintenance cycle.

Pressurising immersible pump operation principle:

It is on the basis of common immersible pump, the sealing of two moving axis, increases an axle movable sealing 68 is installed, and constitutes 3 sealings, further reduces motor room's water inlet probability, improves the movable sealing reliability, and adopts cold-producing medium to the pressurising water pump.

Cooling of design motor and Seal Oil storage chamber 75 increase sealing and heat radiation oil capacity.The oil that stores, raising sealing and heat dispersion.Movable sealing, theoretically leakage arranged all, pressurising in 80 pairs of immersible pumps of design R-114 cold-producing medium pressurising storage chamber, the pressure that utilizes cold-producing medium is to the water pump pressurising.Make the immersible pump internal pressure be higher than ambient pressure, before the R-114 cold-producing medium had not leaked, moisture content can not enter in the water pump, and maintenance cycle obtains prolonging.

When immersible pump was worked summer, because of the wearing and tearing and the other factors of muddy water, lubrication and seal oil micro-leakage, replenished motor room automatically at the oil in the lubrication and seal oil storage chamber 75.Increase along with service life, oil in the oil storage chamber 75 leaks and finishes, the saturated vapor of R-114 cold-producing medium is by pressure reducer 74 decompressions, enter motor room, the pressure of motor room still is higher than atmosphere and river pressure, the oil of motor room still can cool off and lubricated motor in the bottom, can not leak.

Along with the continuation of service life increases, the R-114 cold-producing medium constantly discharges saturated vapor, leaks up to the R-114 cold-producing medium to finish, and water begins the bottom that enters motor room on a small quantity and flow to immersible pump terminal box 61 under atmosphere and river pressure.Water leakage alarm signal electric capacity (Fig. 9; A 61A) termination immersible pump power supply, one end distance is from 10 millimeters of cable coupling box metal bottom surfaces, when the water that enters reaches 10 millimeters height, and the alarm signal electric capacity one end in contact water surface, alarm signal electric capacity discharges to water, is installed in leakage current signal voltage transformer (Fig. 9 of centralized control room; 61B) produce induced voltage signal, utilize this signal; Send the immersible pump water leakage alarm.The synthetic electromotive force of three phase mains is zero, transformer suit three-phase power line unshakable in one's determination, any power line electric leakage, voltage transformer (Fig. 9; 61B) just produce induced voltage, utilize this voltage to send the water leakage alarm signal.

The R-114 cold-producing medium is depressed 3.56 ℃ of degree of evaporating temperature at normal atmosphere.At 6 ℃ more than the temperature, absolute pressure is higher than atmosphere and several meters pressure that water depth forms.The immersible pump degree of depth of summer in river is generally 5---between 8 meters, summer, the river temperature was at 20-25 ℃ of degree, the saturated vapour pressure of R-114 cold-producing medium is higher than atmosphere and river pressure, cold-producing medium is connected by pressure reducer and pipeline and oily apotheca 75, and the pressure setting of pressure reducer is got final product at a little higher than extraneous river pressure.Pressure reducer 74 sealings are installed in the compartment.

Winter, the river plane was low, and atmosphere and river are low to the pressure that immersible pump forms.5-13 ℃ of degree of Yangtze River Water temperature in winter, the saturated vapour pressure of R-114 cold-producing medium reduce automatically but still are higher than the pressure that atmosphere and river form, and that the saturated vapour pressure of R-114 cold-producing medium has not leaked is preceding, water can not enter immersible pump.

The heat of immersible pump outwards dispels the heat by body, also by cutting oil and oil circulating pipe Natural Heat Convection, reduces the immersible pump heat.Pressure reducer 74 has limited liquid refrigerant and has entered in the oil.Filter 78 guarantees that oil pipe is unimpeded.

Immersible pump adopts more piece ring flange seam fixed structure (pump housing ring flange 69), installs gasket seal additional between a pair of ring flange, and the static seal bolt connects.Seal Oil storage chamber 75, R-114 cold-producing medium pressurising storage chamber 80, be connected with the immersible pump cavity.

Oil-filled, the pressurising of water pump has prolonged the immersible pump maintenance time limit greatly.Alarm signal electric capacity (Fig. 9; 61A), leakage current signal transformer 61B, in time send water leakage alarm, guaranteed the safety of large diving pump.

According to the volume of immersible pump, the Seal Oil storage chamber of design and the volume of R-114 cold-producing medium pressurising storage chamber, oil must not be less than 20 kilograms, and cold-producing medium is no less than 5 kilograms.Immersible pump is pressed designing requirement, is ordered to immersible pump production and processing factory.Immersible pump adds 0.5Mpa nitrogen or a small amount of R-12 cold-producing medium examination empty wagons after production, oil-proof is qualified.Before entry is installed, press the design capacity R-114 cold-producing medium of annotating again.

Oil, the high refrigerator oil of filling concentration, for example No. 45 refrigerator oils.Motor insulation, oil resistant and cold-producing medium.After water-proof cable is fit into immersible pump, wrap which floor mylar and, reach oil resistant and cold-producing medium with the epoxide-resin glue sealing.

Shallow immersible pump of water depth and the southern area R-21 cold-producing medium of can annotating is installed, and it depresses 8.9 ℃ of degree of evaporating temperature at normal atmosphere, or the R-133a cold-producing medium, and mark is pressed 6.1 ℃ of degree of evaporating temperature.The shallow water immersible pump that interim use, temperature is higher than 20 ℃ of degree during work, can add the R-11 cold-producing medium, deep well submerged pump can select other high-pressure refrigerant, reach the high workload water pressure of balance and a little higher than water pump.Adopt the following low pressure refrigerant of filling R-21, can be without pressure reducer.

Controlled non-return magnetic valve 3 of the present invention, valve body 90 is connected with miscellaneous part through ring flange 69; 91 import departments are provided with non-return sealing ring 81 at valve pocket, rotating sealing valve collar 84 is set in valve pocket, if sealing valve plate 84 is selected stainless steel for use, then on sealing valve plate 84, iron plate 85 is set, sealing valve collar 84 or the iron plate on it 85 are inhaled mutually with electromagnet 86 generation magnetic force or are repelled, the axle 82 of sealing valve plate 85 is rotated in bearing block 83, reach the effect that opens or closes the valve pocket import.Electromagnet 86 is connected with solenoid 88, and under external Current Control effect, electromagnet 86 produces magnetic force, acts on the valve plate 85, and the control valve plate falls.The adhesive end face of electromagnet 86 is not parallel, and also out of plumb forms an inclination angle each other with non-return sealing ring 81 planes, guarantees the opening angle of sealing valve plate 85, reduces the impact and the resistance of current, and sealing valve plate 85 valve-off that can fall smoothly.

Acting as of controlled non-return magnetic valve; Utilize its controlled non-return feature, the energising of solenoid promptly,, electromagnet 86 holds sealing valve plate 85, stop the immersible pump of this branch road, the startup current of swinging to current and other immersible pump with system, wash the immersible pump filter screen 1 that stops branch road with swinging to flowing water flow, get rid of the adsorbate on the filter screen.

Operation principle is as follows: (referring to Figure 14,15,16,17,18,19,20)

Immersible pump starts, and current are washed movable clack valve 85 open, flow out from valve outlet.Immersible pump is shut down, and movable clack valve 85 is swung under the effect of current, dropped on static time sealing ring 81 of stainless steel down in gravity and system, and non-return is closed.In immersible pump work, when needing reverse flow flushing filter screen, start immersible pump earlier and connect solenoid 88 power supplys, electromagnet 86 produces magnetic field, the movable clack valve 85 of pure iron plate is tightly held, close the immersible pump power supply, the immersible pump current of swinging in current and the other work of system are swung to by this valve body, have realized swinging to current and have washed this branch road immersible pump filter screen 1.

Several immersible pumps of parallel operation are flushing in turn so mutually, has thoroughly solved the filter screen adsorbate and has stopped up immersible pump water inlet problem.The advantage of consumed power not when this valve has air-conditioning work, working stability is reliable, the efficient height.

The processing and implementation mode;

The steel pipe system valve body 90 of selection and system's caliber, coupling is welded on valve body middle part tapping with the first bar circle system of non-magnetic stainless steel stainless steel magnetism-isolating loop 87.Cylinder type electromagnet 86 is pierced into above magnetism-isolating loop 87 is welded on.Non-return sealing ring 81, movable sealing clack valve ring 84 adopt stainless steel processing with rotation seat 83.Movable sealing clack valve 84 is welded to connect with the movable clack valve 85 of pure iron plate, and forming one side is the stainless steel sealing surface, and one side is the pure iron plate suction surface.Static time sealing ring 81 is welded on the interior inlet opening of valve body.Movable sealing clack valve rotating shaft 82 is through in the bearing block 83 to flexibly connecting.Bearing block 83 is welded on the valve body seat board.The movable sealing clack valve can be close to sealing with static time sealing ring 81, can attract 86 to be close to and to be attracted with electromagnet again.

Valve sealing surface is fine finishining on grinding machine.Stainless steel magnetism-isolating loop 87 is welded on the valve body every magnetic, minimizing electromagnet shunt magnetic.Electromagnet 86 usefulness magnetic conduction height, the pure iron bar processing that remanent magnetism is little.It is inclined plane concentric reducer structure that electromagnet 86 attracts end face, enlarges the suction surface of electromagnet 86 and thick pure iron plate 85.

The attraction of electromagnet 86 is greater than the reverse flow impulsive force.Electromagnet concentric reducer structure reduces the impulsive force of reverse flow to movable sealing clack valve 85, and increases the attraction area.Solenoid 88 adopts the dual-fiberglass wrapped flat copper wire coiling, with 36 volt-amperes of full alternating voltages, changes the number of ampere turns of coil, can change magnetism intensity.Coil vacuum the ooze insulated paint and the epoxy resin that oozes use epoxy sealing at last in stainless steel casing, are sleeved on the electromagnet 86, and is fixing with stainless steel bolt 89.

Figure 21 is; Transistor water level control relay circuit figure.

In the drawings, transistor water level control relay 22, priming level control electrode pipe 24, sub-siphon pipe 25, siphon pipe 26, water level control electrode (A ... totally 26 of Z), transistor upper offset resistance (R1 and R2), body pipe below-center offset resistance R 2, motor frequency change controller speed is regulated resistance (R3 ... totally 25 of R28), motor frequency change controller speed regulator potentiometer W1, switching transistor BG, relay (J1 ... totally 25 of J25), power switch (K).

Transistor water level control relay is a prior art, and Figure 21 has only drawn a transistor (BG) and a relay, and other 24 transistor AND gate relays are not drawn.

Operation principle; Closing Switch K transistor water level control relay 22 obtains operating voltage, start pressure pump 2B, motor frequency change controller 23, the high rotation speed operation of pressure pump 2B, water level rises in the priming level control electrode pipe 24, when water reaches the B point, water is connected A point and B point, switching transistor BG conducting, the relay J adhesive, relay J contacting motor frequency change controller speed is regulated resistance R 3, and resistance R 3 is connected in parallel on motor frequency change controller speed regulator potentiometer W1 two ends, has changed motor frequency change controller speed regulator potentiometer W1 two terminal potentials, thereby changed the pump motor rotary speed, regulated discharge.

The central air-conditioning start; Because of the terminal air-conditioner of user (17 or 19) is in uncertain start platform number.User's platform number of starting shooting is few, and hydraulic pressure will rise in the feed pipe L1, and start platform number is many, the interior hydraulic pressure of feed pipe L1 will descend.The rising of this hydraulic pressure or decline are embodied in the rising or the decline of water level in the priming level control electrode pipe 24.Each floor uses 25 transistor water level control relays 22 to be communicated with 25 transistor water level control electrode (B ... Z), 26 water level control electrode (A ... Z) be arranged in the different height of priming level control electrode pipe 24, connect different water level control electrodes (A-Z) by water, control 25 transistor water level control relays 22, successively 25 motor frequency change controller speed are regulated resistance R 3 parallel connections and turn on motor frequency change controller speed regulator potentiometer W1 two ends, thereby the motor frequency change controller that passes through of 25 retainings changes rising of pump motor rotary speed or decline.After user's conditioned water was constant within a certain period of time, water level kept constant in the priming level control electrode pipe 24, and it is constant that the pump motor rotating speed keeps.

Pump rotary speed degree debug process; Closing Switch K, water is communicated with electrode A and electrode B, regulates value resistance R 1 and resistance R 2 partially, makes switching transistor BG conducting, the relay J adhesive.Water disconnects electrode A and the electrode B that is communicated with, and transistor BG ends, and the relay J contact disconnects.Regulate resistance R 1 repeatedly and satisfy aforementioned requirement with resistance R 2.

Pump motor speed debug process; Connect input and the out-put supply and the motor speed dial gauge of motor frequency change speed setting controller 23 and motor.Power-on; Regulating frequency-variable controller speed regulator potentiometer W1 makes motor speed be designated as 96% rated speed.Powered-down; Measure frequency-variable controller speed regulator potentiometer R4 two ends resistance value, select the resistance R 3 of a same resistance value to be welded on speed regulator potentiometer W1 two ends, the debugging of 96% rated speed finishes, and this rotating speed is the water pump 2B rotating speed that water connection A and B are ordered.Again power-on; Regulating frequency-variable controller speed regulator potentiometer W1 makes motor speed be designated as 92% rated speed.Powered-down; Measure frequency-variable controller speed regulator potentiometer W1 two ends resistance value, select the resistance R 3 of a same resistance value to be welded on speed regulator potentiometer W1 two ends, the debugging of 92% rated speed finishes, and this rotating speed is the pump rotary speed that water connection A and C are ordered.The rest may be inferred by analogy; Finish water and connect A ... water pump 4% rated speed that Z is ordered.An English words generatrix is connected in the every rising of water level, pump rotary speed just descends 4%, reaching hydraulic pressure raises, water level raises in the priming level control electrode pipe 24, reach to connect and go up pair of electrodes point, 22 actions of corresponding crystal pipe water level control relay, water pump 2B rotating speed descends 4%, and water level descends in the priming level control electrode pipe 24, water disconnects the pair of electrodes point, pump rotary speed 4% rated speed that raises.

Water continues to rise and saves logical pair of electrodes, and by the effect of transistor level relay, water pump 2B rotating speed descends 4% again, falls end under water and opens pair of electrodes, and water pump 2B rotating speed just raises 4%, realizes full-automatic 25 retainings, the purpose of regulating water pump 2B rotating speed.

The rotating speed debugging finishes; The resistance R 3 of 96% rotating speed is connected in the transistor water level control relay (22) of (Figure 21) B point line ... the resistance (R3) of 4% rated speed is connected in the transistor water level control relay 22 of Z point line, disconnects frequency converter speed regulator potentiometer W1 middle-end travelling arm line (the W1 travelling arm is beaten the fork place) at last.25 rotational speed regulation resistance (R3 ... R28) be connected in 25 transistor water level control relays 22, connect associated connections, water pump 2B rotating speed, finish by transistor level relay 22 control motor frequency change speed regulators 23 speed settings.

By frequency control, it is few to have reached air-conditioning start platform number, and hydraulic pressure raises, and reduces the purpose of pump rotary speed automatically, and user's air-conditioning start platform number is many, and hydraulic pressure descends, and the pump rotary speed of frequency control raises automatically, hydraulic pressure raises, and has realized that maximization is energy-conservation.

If the water level control electrode of 50 pairs or other quantity is set in the priming level control electrode pipe 24, control the transistor water level control relay 22 of 50 or other quantity, by the speed adjusting resistance R3 of corresponding quantity, can realize 2% or the pump rotary speed of the respective amount control accuracy of regulating.

Figure 21 cuts in frequency by the relay contact (can be many contacts) in the transistor water level control relay 22 to regulate resistance R 3, change motor frequency change controller speed regulator potentiometer W1 two terminal potentials, thereby change the amplitude of power supply and the method for frequency shift motor speed degree by the motor frequency change speed setting controller, also can adopt the self-regulating method control of pressure controller or other stepless rotary speed.It is prior art that the motor frequency change speed setting controller changes motor speed, repeats no more here.

During system debug; By 26 water level control electrode (A that are provided with in the mobile priming level control electrode pipe 24 of height ... Z) high and low position is adjusted water pump 2B suction inlet end water pressure between 60-90Kpa (absolute pressure), and this is realized by sub-siphon pipe 25.

The water journey resistance design of terminal air-conditioner (17 and 19) is at 20-30Kpa, and the water journey resistance of horizontal floor feed pipe and horizontal floor drainpipe designs at 5-10Kpa.Soil stack L2 is because be connected with vavuum pump, and space pressure is below the 3Kpa (absolute pressure) in the soil stack.Like this; The automatic control action of factor siphon pipe 25 and water pump 2B rotary speed, operating pressure is negative pressure in the terminal air-conditioner of water pump 2B suction inlet end and floor, system very low with water pressure reached the energy-conservation maximization (system water pressure is low more, and it is few more that water pump consumes electric power) of conditioned water.

The effect of factor siphon pipe 25: the lift of water pump 2B is chosen as 2---and 3 meters, flow is chosen as the summation that this floor Air-conditioner design discharge adds top floor Air-conditioner design discharge.Central air-conditioning is at the loaded work piece below 70% because of 80% time, and the pump rotary speed degree is regulated by frequency converter and reduced, and noise and wearing and tearing significantly reduce.

Sub-siphon pipe 25 is a pipe with priming level control electrode pipe 24, or priming level control electrode pipe 24 is arranged in the sub-siphon pipe 25, their vertical position length can be 11 meters (greater than siphon heights of an atmospheric pressure, water), be vertically mounted in the architecture pipe well, the pressure pump water inlet of every floor connects an end of one, and the other end connects siphon pipe 26.

During system debug; Water level control electrode position is set can adopt lucite pipe or in water level control transistor relay water level is set and just show luminous 2 utmost point pipes, thereby convenient mobile 26 water level control electrode (A of height of water level decision that observe ... Z) installation high and low position, the pressure of control water pump 2B suction inlet.
