Description
Technical field
The utility model relates to a kind of pump, and the efficient suction pump of the liquid medium that particularly a kind of pump combines with negative pressure device is the innovation to traditional suction pump.
Background technique
Pump is a visual plant of carrying liquid medium, and along with the high speed development of industrial and agricultural production, the use occasion of pump is a lot, fields such as its extensive use industry, agricultural, oil, chemical industry, pharmacy, environmental protection, mining industry, urban construction.The kind of pump in suction low level liquid medium has following several at present: A, self-priming pump, and it utilizes the medium that prestores in the pump chamber, will could run well after the discharge of the air in the intake line in inner cyclic process, and its shortcoming is that period of exhaust is long, efficient is low.B, rotary-vane vaccum pump, it utilizes the volume-variation of rotation scribing that the air in the pump chamber is discharged, but its speed of exhaust is low, generally in 2～70L/S scope.C, Ordinary Centrifugal Pumps are in conjunction with water ring or rotary-vane vaccum pump, make vacuum condition for pump series, primer pump comes draining after making medium enter pumping system under atmospheric pressure, its deficiency is that the vacuum pump period of exhaust is longer, unstable, service life of equipment is low, can not adapt to the special use occasions of chemical industry such as acid, alkali, salt.Kind suction pumps such as submersible pump, Under Water Pumps, vertical diagonal flow pump are still arranged, and it adapts to different occasions and uses.A kind of automatic control turbine synchronous discharging-suction pump of nearly report, its transfer pump top is provided with negative pressure device, negative pressure device is provided with gas-liquid separator, and a liquid level sensor is housed on gas-liquid separator, and the vacuum blower on transfer pump and the negative pressure device is respectively by different driven by motor.This structural advantages is that period of exhaust is short, water outlet is fast, but has defective on its structure, and transfer pump and blower fan will be by two driven by motor, and compactness promptly takes up space and waste material inadequately, still needs improved place.
Summary of the invention
The utility model provides a kind of efficient suction pump, and the induced draft fan of its transfer pump and negative pressure device provides power by a motor altogether, thereby reaches compact structure, period of exhaust is short, water outlet is fast, reliability is high, cost-effective purpose.
The technical solution of the utility model is:
A kind of efficient suction pump, comprise the pump housing, suction pipe, blower fan, motor, pressure-equalizing pipe, on the pump housing, have relief opening with the pump intracavity inter-connection, it is characterized in that between the blower fan axle of machine shaft and negative pressure device, being provided with engaging and disengaging gear, machine shaft is connected with the blower fan axle by engaging and disengaging gear, machine shaft connects by coupling with the front pump wheel shaft, is provided with level sensor on pump cavity, is provided with pressure-equalizing pipe between negative pressure device and front pump cavity; On pressure-equalizing pipe, be provided with valve, on motor, be provided with the electric motor starting controller; Level sensor, valve, engaging and disengaging gear and electric motor starting controller are connected with control circuit by transmission line respectively.
Described negative pressure device comprises housing, blower fan, and housing is installed in the upper position of horizontal machine, is provided with pressure-equalizing pipe in case top, and negative pressure device is connected with pump cavity by pressure-equalizing pipe; Engaging and disengaging gear is installed in the outer side surface of negative pressure device housing, and control circuit places the housing opposite side, by engaging and disengaging gear from close, thereby the control blower fan stops and open.
Described pump is blade type or positive displacement pump; Negative pressure device can replace with civilian or industrial vacuum cleaner.
This pump intake places the transfer pump bottom, and inlet downwards.
The motor of this suction pump is a horizontal machine, and machine shaft and Pump wheel shaft are on the same horizontal axis.
During start; engaging and disengaging gear closes; transmit machine shaft power; the fan starting of negative pressure device vacuumizes; produce negative pressure; when suction pipe and pump chamber internal pressure are lower than atmospheric pressure; liquid medium enters suction pipe and pump chamber under atmospheric pressure; when liquid arrival impeller center line was above, liquid level sensor was transferred to control circuit with signal, and pump drives to put into operation automatically; this moment, engaging and disengaging gear separated; the blower fan autostop, the valve on the pressure-equalizing pipe is also closed automatically, prevents that liquid from pouring in the negative pressure device.During termination of pumping, open exhaust port, pump chamber is communicated with atmosphere, liquid comes off under atmospheric pressure automatically, pump chamber and suction pipe liquid is fallen after rise become empty.
Characteristics of the present utility model:
1. the start of this suction pump is shut down just sky of pump with regard to water outlet, reaches synchronous row and inhales, and pump has suction capacity;
2. the shared motor of the negative pressure device and the pump housing is saved cost, makes more compact structure, reasonable simultaneously;
3. prolong motor working life, the running earlier of the blower fan of negative pressure device produces negative pressure during start, like this, just connects the load of an appropriateness when equaling electric motor starting, and electric current is excessive and burn motor when preventing to start effectively;
The efficient height, save effectively, the maintenance expense is low.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A view of the utility model Fig. 1.
The contrast accompanying drawing specifies its structure.
In Fig. 1～2, this efficient suction pump comprises the pump housing, suction pipe and blower fan, suction port 14 is downward, suction pipe 2 is connected with the pump housing 1 tightness, negative pressure device 6 places the upper position of motor 3, is connected with pressure-equalizing pipe 8 between negative pressure device and pump cavity, establishes level sensor 12 on pump cavity, machine shaft is connected by 7 of engaging and disengaging gear 10 and blower fans, and machine shaft is connected with Pump wheel shaft by coupling 11.During operation, starting electrical machinery, engaging and disengaging gear closes; the driven by motor blower fan rotates, thereby produces negative pressure and be delivered in the pump cavity atmospheric outside effect by pressure-equalizing pipe; liquid enters in the pump cavity along suction pipe; when liquid level arrived pump cavity level sensor position, level sensor was passed to control circuit 5 with signal, the entry into service of control circuit instruction pump; engaging and disengaging gear separates simultaneously; blower fan is shut down, and the valve 9 on the pressure-equalizing pipe is closed, to prevent irritating negative pressure device on the liquid.During shutdown, open exhaust port 15, pump chamber is communicated with atmosphere, liquid falls after rise under atmospheric pressure automatically, makes pump cavity become empty, avoids liquid and corrodes for a long time.
