Description
Technical field
The detection of pressurized equipment and protection technique field, specially one in the utility model device secondary water-supply complete set of equipments
Kind pressurized equipment duplicate protection detection device.
Background technique
When pumping operation, when water tank or municipal administration are cut off the water, water pump can only dally water pump, this not only wastes electric energy, but also
Also water pump damage can be easily led to because water pump dallies and heats up, in the water pump with water-shortage protection device of existing commercial type mostly
With a kind of electron pressure switch, the pressure switch is for detecting the hydraulic pressure in water pump, in the lower situation of hydraulic pressure,
Pressure switch will disconnect the power supply of water pump.On the one hand this pressure switch involves great expense, result in this with excessive low water level protection dress
The water pump set holds at high price；On the other hand, this pressure switch is easy to damage and cause to fail；
In addition it discloses a kind of water pump water shortage protective devices for the Chinese patent of 205858634 U of Patent No. CN, including
Shell, which is characterized in that shell is axially arranged along water pump, and two electrodes separated, electrode and water pump control are equipped in shell
Device processed electrical connection, enclosure interior communicate with the outside world, although solving the problems, such as that water pump dallies in water-stressed conditions and has a structure
Simply, low cost, stability in use is good, but its by liquid-level probe be placed on pump body do not only take up pump body space and
The collision of flabellum and liquid-level probe is caused to result in greater loss when the pico- eccentric motion of flabellum.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of pressurized equipment duplicate protection detection devices.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is a kind of pressurized equipment duplicate protection detection
Device, including the pump housing, the left side of the pump housing are equipped with controller, and the upper end of the pump housing left side is equipped with connecting tube, the company
The other end of adapter tube is equipped with electro connecting pressure gauge, and liquid-level probe, the liquid level are equipped between the electro connecting pressure gauge and the pump housing
Probe is all connected on the controller with the electro connecting pressure gauge, and the bottom of the pump housing left side is equipped with water inlet, the pump
The bottom of body right side is equipped with water outlet, while being equipped with motor in the top of the pump housing.
Optimal technical scheme as the utility model: the connecting tube is arranged to " L " shape, and is welded on the pump housing.
Optimal technical scheme as the utility model: the liquid-level probe is threadedly coupled with the connecting tube, and
Junction is wound with unsintered tape, and the liquid-level probe is mounted on 90 degree of connecting tube of corner.
Optimal technical scheme as the utility model: the floor of the electro connecting pressure gauge setting value is lower than municipal administration pipe
Network pressure power 0.1Mpa.
By adopting the above technical scheme, the beneficial effects of the utility model are: 1. use electro connecting pressure gauge, when municipal administration is cut off the water
When, the minimum pressure limit of setting, pressure meter switch signal feeds back to controller, the output that controller is cut off the power, electricity immediately
Machine is out of service, to protect motor；
2. entering bulk gas when municipal administration is cut off the water in the pump housing, water supply network water consumption is small at this time, pump housing water outlet it is non-return
Under valve gear failure conditions, ductwork pressure backwashes to tank body, compressed gas, makes tank interior pressure rise, causes electric contact pressure
The pressure that power table detects is in normal pressure value, pressure gauge failure, but is installed on top level probe and detects tank interior
Have no liquid level, liquid-level probe feedback signal protects motor to controller and the output cut off the power.
3. since connecting tube is welded on the outside of the pump housing, to prevent the liquid-level probe possibility that also flabellum collides, Jin Erbao
Demonstrate,prove that the operation of pump body flabellum is without hindrance, it is further guarantee pressurized equipment using safe.
Detailed description of the invention
