Abstract
A water drawing barrel pump comprises a motor, a pump, a pump shaft and a pump base. Wherein, the pump is arranged on the pump base. The pump shaft, a water outlet and a water outlet are arranged in the pump. An output shaft of the motor is connected with the pump shaft. A water drawing barrel is positioned on an external side of the pump. The pump base and the pump are arranged in the water drawing barrel. An upper end of the water drawing barrel is arranged with a water drawing pipe. The water outlet of the pump is positioned through a lateral wall of the water drawing barrel through a pipe. Before starting the pump, it is necessary to firstly fill the barrel with water to a cross section of the water drawing pipe. After the pump is started, water level in the barrel declines, thus forming negative pressure in the barrel. Water in a pool rises through a suction pipe. As the water level in the barrel declines to a cross section of the water inlet of the pump, the suction pipe is fully filled with water to switch a water suction system into operation. The utility model forms negative pressure to the suction pipe through the water drawing pipe to realize pump start, save a vacuum pump and a moisture segregating tank. It is unnecessary to mount a bottom valve for the suction pipe to avoid influencing water pump operation due to water leakage from the bottom valve. The utility model has the advantages of simple structure and easy utilization.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to pump, particularly a kind of diversion tube pump.
Background technique:
The application of priming pump is very universal, especially rural water conservancy irrigation, aquaculture, urban water or the like, priming pump is installed in above position, water source usually in the using process, thereby the air in the aqueduct need be taken out during startup so that produce negative pressure and extract the water source out, the technology that the startup of traditional water pump of the prior art is adopted is such, utilize the vacuum pump diversion system, realize water and air separation, bottom valve also is equipped with in the suction sleeve bottom, and this mode exists water pump structure complexity, cost height, moves shortcomings such as unreliable.
Summary of the invention:
The purpose of this utility model provides a kind of diversion tube pump, and described this diversion tube pump will solve priming pump complex structure in the prior art, cost height, move insecure technical problem.
This diversion tube pump of the present utility model is made of motor, the pump housing, pump shaft and pump seat, the described pump housing is arranged on the described pump seat, be provided with pump shaft, water outlet and water intake in the pump housing, the output shaft of described motor is connected with pump shaft, wherein, the arranged outside of the described pump housing has a diversion tube, and pump seat, the pump housing all are arranged in the diversion tube, the upper end of diversion tube is provided with an aqueduct, and the water outlet of the pump housing passes the sidewall of diversion tube by pipeline.
Further, the upside of described diversion tube is provided with a motor cabinet, and described motor is arranged on the described motor cabinet.
Further, in the described diversion tube, following partially filled of aqueduct interface has water.
Working procedure of the present utility model is such: before the diversion tube pump startup, be filled with water to earlier aqueduct interface section in tube, be atmospheric air in interior space of tube that aqueduct interface section is above and the suction sleeve.Behind the starting mode of pump, drawdown in the tube, an inner air pressure is reduced gradually and form negative pressure, the water in pond then rises gradually by suction sleeve, and when water level in the tube was reduced to the water intake section of the pump housing, suction sleeve had been full of water, then suction system enters operating condition, air is taken to outside the tube by water, and reaches normal operation along with the continuity of working time in the tube.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model utilizes the diversion tube that suction sleeve is formed negative pressure, realizes the startup of pump, thereby has saved vacuum pump and gas water separation tank, and suction sleeve also needn't be adorned bottom valve, and having avoided influences the disadvantage of pump operation because of bottom valve leaks.Simple in structure, easy to use.
Description of drawings:
Fig. 1 is a diversion tube pump structure schematic representation of the present utility model.
Embodiment:
As shown in Figure 1, a kind of diversion tube of the utility model pump, by motor 7, the pump housing 3, pump shaft 5, pump seat 1 constitutes, the described pump housing 3 is arranged on the described pump seat 1, pump shaft 5 is arranged in the pump housing 3, the output shaft of motor 7 is connected with pump shaft 5, be provided with water outlet 2 and water intake in the pump housing 3, wherein, the arranged outside of the described pump housing 3 has a diversion tube 4, pump seat 1, the pump housing 3 is arranged at the inside of diversion tube 4, water outlet 2 passes the sidewall of diversion tube 4 by pipeline, the upside of diversion tube 4 is provided with a motor cabinet 6, and motor 7 is arranged on the described motor cabinet 6, and the upper end of diversion tube 4 is provided with an aqueduct 8.
Working principle of the present utility model is: before the diversion tube pump startup, be filled with water to earlier aqueduct interface section 1 in tube, space and suction sleeve are atmospheric air from section 0 to section 1 in the tube of aqueduct interface section more than 1.Behind the starting mode of pump, drawdown in the tube, an inner air pressure is reduced gradually and form negative pressure, the water in pond then rises gradually by suction sleeve, and when water level in the tube was reduced to the water intake section of the pump housing, suction sleeve had been full of water, then suction system enters operating condition, air is taken to outside the tube by water, and reaches normal operation along with the continuity of working time in the tube.
Claims (3)
