Abstract
The utility model relates to a vacuum exhaust and suction pump which comprises a pump and an exhaust pipe. The lower end of the exhaust pipe is inserted into a liquid suction pipe of the pump. The utility model is characterized in that an air outlet end of the exhaust pipe is provided with a blower, and an air outlet of the exhaust pipe is connected with an air inlet of the blower by air tightness. The utility model has the advantages that the utility model has no erosion, and besides flow passage components, the rest part have no contact with a medium. The service life of running of the complete machine is five to ten times of a dirt-submersible pump. The utility model needs not a bottom valve, and suction loss is small. The pump has the functions of starting at high liquid level and shutdown at the low liquid level, and has a shutdown device with intelligent protection. After the medium is sucked, the utility model can carry out the automatic shutdown to realize remote control and electric power and manpower can be saved. The utility model can select vertical type, or horizontal type, or movable type, or fixing type installation according to the work condition and environment. Efficiency is enhanced three percent to five percent in general. Compared with the traditional non-seal, self-control, and self-suction pump, the efficiency is enhanced ten percent to thirty percent and the effect of saving energy is quite obvious.
Description
(1) technical field
The utility model relates to a kind of pump, particularly relate to a kind of at pump liquid sucting port or the outlet pipe that is provided with of liquid outlet place on be equiped with the pump of centrifugal blower.
(2) background technique
Pump is one of capital equipment of carrying liquid medium, is widely used in industrial departments such as oil, chemical industry, electric power, urban construction, environmental protection, sewage treatment, food, pharmacy, synthetic fiber, mining, papermaking, building, metallurgy, fire-fighting, tap water, boats and ships and the unloading of groove tank car.Pump extensive technological measure that adopts in the applying working condition of suction low level medium has at present:
1, Ordinary Centrifugal Pumps adapted water ring or sliding vane rotary vacuum pump: make vacuum condition to pumping system, priming pump comes draining after making medium enter pumping system under atmospheric pressure, the disadvantage that this kind method exists is that the vacuum pump period of exhaust is long, service life of equipment is low, the rate of fault height, the special operation condition of incompatible acid, alkali, salt chemical product etc.
2, self-priming pump: its working principle is to utilize the medium that prestores in the pump chamber under the effect of pump, with after the discharge of the air wrapped folder in the intake line, could normally move in interior circuit process, and its shortcoming is that period of exhaust is long, and efficient is low.
3, building low level pump house or a high position held the liquid case: to pump manufacturing inlet pressure head, its disadvantage is that capital investment is big, and floor space is big, the equipment maintenance difficulty, more than several technological measures all exist the problem that equipment in the winter time must the insulation heating.
4, the Pump Suction Nozzle end is installed bottom valve: after pouring into diversion before the pump running, and starting operation, its drawback is the perishable leakage of bottom valve, must often change.
(3) summary of the invention
The purpose of this utility model provides that a kind of period of exhaust is short, water outlet is fast, and floor space is little, little investment, saves the vacuum discharging-suction pump of the energy.
The technological scheme that adopts is:
The vacuum discharging-suction pump comprises pump and outlet pipe, and insert in the pick-up tube of pump the lower end of outlet pipe.Its technological points is to be provided with blower fan at the other end place of outlet pipe, and the air outlet of outlet pipe is connected with the suction port tightness of blower fan.Above-mentioned blower fan is single-stage or multistage centrifugal blower fan, also can be single-stage or multistage Wormwheel fan.
For when the blower fan suction imbibition inner air tube, can not make the low level medium enter blower fan from outlet pipe with gas, blower fan is damaged, on gas exhaust piping, install gas-liquid separator.
Safer in order to ensure blower fan, on above-mentioned outlet pipe, install solenoid valve.
Above-mentioned blower fan, solenoid valve, gas-liquid separator are installed in the protective housing.
The drive motor of above-mentioned blower fan, the work of pump drive motor and solenoid valve is controlled by setup program by an electric control cubicle.
Above-mentioned gas-liquid separator can preferably commercially available gas-liquid separator, also can adopt the gas-liquid separator of our factory's design.As be suitable for the gas-liquid separator that the horizontal vacuum discharging-suction pump uses, it by housing and crosswise fixed at least one dividing plate in housing form, the through hole (see figure 1) is arranged on the dividing plate; Be suitable for the gas-liquid separator that the vertical vacuum discharging-suction pump uses, it by housing and at least one dividing plate that vertically is installed in the housing form (see figure 3).
The output shaft of the drive motor of above-mentioned blower fan main shaft and blower fan adopts belt to connect or gear connects, and also can adopt coupling directly to connect.
With the horizontal vacuum discharging-suction pump is example, and its working principle is:
Before the startup, by external automatical control system, open solenoid valve earlier after, start centrifugal blower, with instantaneous vacuumizing in the suction pipe of pump and the pump chamber, blower fan is discharged air, and separator is with gas-liquid separation, when degree of vacuum reaches certain value in the pump, medium enters in the pump under atmospheric pressure, and after being full of medium in the pump, liquid level sensor sends command signal, automatically start " vacuum discharging-suction pump ", pump normal operation input.This moment closed electromagnetic valve, centrifugal blower stops automatically.When medium is inhaled sky, the pump autostop, robot control system(RCS) can also realize high liquid level Auto Power On, low liquid level autostop.
The vacuum discharging-suction pump of our factory invention has following advantage:
1, during suction low level medium, install without self filling type, use first also to need not manually water filling or diversion in pump, start can be discharged medium.Be fit to away from the water source or be difficult for the medium of drainage (being mixed with reaction) with water.
2, after vertical pump was shut down, noresidue medium in suction pipe and the pump chamber need not pump and suction pipe are taked the insulation measure, was applicable to fully not to have in winter, particularly extremely frigid zones under the insulation operating mode to install and use.
When 3, being used to carry sewage, slime water and slip, need not backwash.
4, can cancel the infrastructure of low zone pump room or head-tank, install liquid level top, and volume is little, reduce investment outlay and take up an area of, and maintenance is convenient.
5, no etch, except that flow passage components, remaining part does not contact with medium.Complete machine service life is Under Water Pumps, submerged pump 5-10 times.
6, need not bottom valve, suction loss is little, the efficient height.
7, this pump is shut down the function except that possessing the low liquid level of high liquid level starting, but also has the intelligent protection arresting gear, inhales empty back autostop at medium, can realize telecontrol, saves electric power, manpower.
8, can select vertical, horizontal, mobile or fixed installation according to work condition environment.
9, efficient generally improves 3%-5%, does not have the high 10%-30% of sealing automatic control self-priming pump efficient than tradition, and energy-saving effect is very obvious.
