Abstract
The utility model relates to a novel booster pump with a pressure set device. The utility model is composed of a pump body, a one-way valve and a pressure switch. The utility model is characterized in that a water inlet of the pressure switch or the interior of a water inlet pipe is provided with filling material which can permeate water. The utility model has no need of pressure buckets, the volume is small, the space is not occupied, the installation is convenient, and the utility model has no traditional water pulse phenomenon. An electric motor has no sudden stop and sudden move due to the interference of the water pulse, and thus the noise is small and the energy consumption is small. The utility model has the advantages of simple structure, low failure rate, long service life, wide pressure control range, and high reliability.
Description
The utility model relates to a kind of new type pressurized pump with pressure setting device.
Under normal conditions,, can't lean on the pressure of self water to be delivered to higher places such as high building or highland, must finish this work by suction booster because the hydraulic pressure of tap water is limited.In order to reach the purpose of automatic supercharging feedwater, can realize by dual mode: a kind of is water tank to be set in the commanding height or to build water tower, comes the running of control of pump by the ball float in water tank or the water tower; Another kind is that pressure control device directly is set on water pump, and when the hydraulic pressure of output reached certain numerical value, this device can shut down automatically; Otherwise, when hydraulic pressure is lower than certain numerical value, connects automatically and make pump working, realize the purpose of self water feeding.Chinese patent ZL97228014.6 discloses a kind of " compression pump with pressure setting device ", this device has been set up the valve of preventing on the pump housing, because the valve arrangement complexity of preventing, difficulty of processing is big, in use result in blockage easily again, so cost height, working life are short.
It is a kind of simple in structure that the purpose of this utility model is to provide, and volume is little, noise is low, the power consumptive province, cost is low, the life-span is long, the safe and reliable new type pressurized pump with pressure setting device.
The purpose of this utility model is achieved through the following technical solutions: it is by the pump housing, one-way valve and pressure switch constitute, the pump housing comprises a shell, it in the shell cavity of a hollow, one impeller is housed in the cavity, cavity is divided into inhalant region and exhalant region, be respectively arranged with and extraneous water intake and the water outlet that communicates at inhalant region and exhalant region, one-way valve is contained in the water inlet, pressure switch be installed in water outlet near, it is characterized in that: be provided with in the water inlet of pressure switch or its intake pipe and can allow the packing of water infiltration, the water inlet aperture of pressure switch and pump housing junction is less than the caliber of pressure switch intake pipe.
The utility model need not pressure pot, and body is small and exquisite, do not take up room, and simple installation, no traditional aquapulse phenomenon makes motor can not stop suddenly because of the interference of aquapulse to neglect and move, so noise is little, energy consumption is low; That the utility model also has is simple in structure, rate of fault is low, long service life, pressure control range is wide, reliability is high advantage.
Fig. 1 is the utility model embodiment's a complete machine schematic appearance.
Fig. 2 is the utility model embodiment one partial cutaway diagrammatic sketch.
Fig. 3 is the structural representation of the utility model embodiment two pressure switch.
In order to make the utility model structure clear more complete, be described further below in conjunction with embodiment.
Embodiment 1:
As illustrated in fig. 1 and 2: the utility model is made of the pump housing 1, one-way valve 2 and pressure switch 3, the pump housing 1 comprises a shell, it in the shell cavity of a hollow, one impeller 5 is housed in the cavity, make cavity be divided into inhalant region 6 and exhalant region 7, be respectively arranged with and extraneous water intake 8 and the water outlet 9 that communicates at inhalant region 6 and exhalant region 7, one-way valve 2 is contained in water intake 8 places, it is characterized in that: be provided with the packing 10 that can allow water permeate in the intake pipe of pressure switch 3, the water inlet aperture of pressure switch and pump housing junction is less than the caliber of pressure switch intake pipe; Packing 10 is sponge, silk group or fiber tuft.After the pulsating water in the exhalant region flow through packing 10, dynamic pulsating water had just become the water of the no pulse with steady pressure, makes pressure switch not be subjected to the interference of traditional water pulse, can feel hydraulic pressure automatically and accurately.
Embodiment 2:
As shown in Figure 3, the utility model is to be provided with the packing 11 that can allow water permeate in the water inlet of pressure switch 3, and this packing is textile or fibrous material.
Claims (3)
1. new type pressurized pump with pressure setting device, constitute by the pump housing, one-way valve and pressure switch, the pump housing comprises a shell, it in the shell cavity of a hollow, one impeller is housed in the cavity, cavity is divided into inhalant region and exhalant region, be respectively arranged with and extraneous water intake and the water outlet that communicates at inhalant region and exhalant region, one-way valve is contained in the water inlet, it is characterized in that: be provided with in the water inlet of pressure switch or intake pipe and can allow the packing of water infiltration, the water inlet aperture of pressure switch and pump housing junction is less than the caliber of pressure switch intake pipe.
2. the new type pressurized pump with pressure setting device according to claim 1 is characterized in that: the packing in the intake pipe is sponge, silk group or fiber tuft.
