Description
(1) technical field
The utility model relates to a kind of pump, particularly relates to the pump of a kind of transfer pump and negative pressure device combination.
(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 automatic control turbine vacuum discharging-suction pump of the energy.
The technological scheme that adopts is:
Automatic control turbine vacuum discharging-suction pump, comprise the pump housing, suction connection, the top of the described pump housing offers the relief opening that links with pump housing inner chamber, the relief opening that it is characterized in that described pump housing top gives exhaust by a negative pressure device, described negative pressure device is provided with a gas-liquid separator, is equiped with a liquid level sensor on the described gas-liquid separator at least.The bottom of described gas-liquid separator offers an intakeport.
The bottom of above-mentioned gas-liquid separator offers an intakeport, and this intakeport is connected by the relief opening of a sucking pipe with pump housing top, and links, and the intakeport of gas-liquid separator bottom is higher than the relief opening on pump housing top.
The intakeport of above-mentioned gas-liquid separator bottom also can directly be connected with described suction connection by a connecting tube; And be connected with a pressure-equalizing pipe between the relief opening on pump housing top and the top of described gas-liquid separator.
Be equiped with a control valve on the above-mentioned pressure-equalizing pipe.
Above-mentioned negative pressure device comprises housing, is arranged at vacuum blower and motor in the housing.
Above-mentioned negative pressure device is industrial or civilian vacuum cleaner.
Above-mentioned vacuum blower is single-stage or multistage centrifugal blower fan, and single-stage or multistage Wormwheel fan or vacuum cleaner also can be diaphragm-type vacuum pump, Roots pump, rotary-vane vaccum pump or vacuum displacement pump.
Above-mentioned transfer pump is blade type or positive displacement pump.
Be connected with a branched pipe between above-mentioned negative pressure device and the gas-liquid separator, be equiped with a vacuum solenoid on the branched pipe.
Its working principle is:
Before the startup, by the control of automatic control turbine discharging-suction pump, open solenoid valve earlier, start negative pressure device, with the instantaneous vacuum that is evacuated in the suction pipe of pump and the pump chamber, when degree of vacuum reached certain value in the pump, medium entered in the pump under atmospheric pressure, after being full of medium in the pump, medium enters gas-liquid separator through sucking pipe, medium liquid level after gas-liquid separation rises to liquid level sensor and gives and establish the position, and liquid level sensor sends command signal, automatically the primer pump normal operation input.This moment closed electromagnetic valve, negative pressure device 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 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.
