Abstract
The utility model discloses a water supply cut-off warning device for a gas pump. The water supply cut-off warning device is characterized in that an anti-explosion bell (1) is arranged in a gas pump duty room; an electro connecting pressure gauge (2) is arranged in the position of the water inlet pipe of a water pump; an anti-explosion single linkage button (3) is arranged in the position of an elevated water basin; the anti-explosion bell (1), the electro connecting pressure gauge (2) and the anti-explosion single linkage button (3) are serially connected through a cable; the water supply cut-off warning device is powered up through voltage of 127V; and a pair of auxiliary lever trigger mechanisms is arranged at the position of the anti-explosion single linkage button (3). The water supply cut-off warning device solves the problem in water supply cut-off warning for the gas pump through a simple method, and is good in effect and low in cost.
Description
Technical field
The utility model relates to the mining machinery technical field, relates in particular to a kind of gas pump water break alarm device.
Background technology
At present, the gas pump that moves on the ore deposit is water-ring vacuum pump, and this pump safety is good, reliable, must guarantee to continue to supply water but be in operation.Water supply on the ore deposit relies on water pump and head-tank, in case problem appears in one of them point, for example occurring supplies water interrupts, and can cause the appearance of the fault such as rotor locking, forces gas pump to be shut down., safety water supply problem lasting for solving, the safe and reliable operation of assurance gas pump, water break alarm device is used in development.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of gas pump water break alarm device, to solve gas pump circuit water alarm problem.
The technical solution of the utility model is: every gas pump is installed an explosion-proof electric bell, an electro connecting pressure gauge and an explosion-proof simply connected button, and the three is cascaded, and supply voltage is 127V, and power supply is taken from lighting signal comprehensive protector.Electric bell is arranged on the gas pump janitor's room, and electro connecting pressure gauge is arranged on the pump water inlet place, and explosion-proof simply connected button is arranged on head-tank return pipe low pool place.The triggering of explosion-proof simply connected button is realized by a leverage.
Leverage comprises lever, and lever one end is bucket, and hole, the lever other end are arranged at bucket bottom is trigger ball.
The operating principle of this warning device is: when pump water inlet was cut off the water supply, the electric contact pressure list index returned zero, and constant open contact becomes constant close contact, and electric bell gets electric, reports to the police; When the head-tank water level is low, the head-tank return pipe flows out without backwater, triggers explosion-proof simply connected button by a mechanical device, and the button constant open contact becomes constant close contact, and electric bell gets electric, reports to the police.
The utility model has solved gas pump circuit water alarm problem, and is simple and practical, and on the ore deposit, existing 9 gas pumps are are all installed and used, and have guaranteed the reliability service of gas pump.
Description of drawings
Fig. 1 is gas pump water break alarm device schematic diagram;
Fig. 2 is gas pump supply channel schematic diagram;
Fig. 3 is the leverage principle schematic.
The specific embodiment
As Fig. 1 and Fig. 2, a kind of gas pump water break alarm device, explosion-proof electric bell 1 is arranged on the gas pump janitor's room, and electro connecting pressure gauge 2 is arranged on the pump water inlet place, and the head-tank place arranges explosion-proof simply connected button 3, adopts cable series connection between the three, the 127V Power supply.When pump water inlet was cut off the water supply, the electric contact pressure list index returned zero, and constant open contact becomes constant close contact, and electric bell gets electric, reports to the police.At head-tank and 3, explosion-proof simply connected button, a simple leverage is installed as Fig. 3: its lever is the round steel of a Φ 16, an end with trigger ball 7 is placed in explosion-proof simply connected button 3 places (can be up and down), the other end is hung a bucket 5,3 to 5 holes 6 are stamped in bucket 5 bottoms, the head-tank backwater flows into bucket 5, bucket 5 water utilize lever principle to make the trigger ball 7 of round steel lever 4 other ends depress explosion-proof simply connected button 3 when full, and alarm circuit disconnects, and explosion-proof electric bell 1 is not reported to the police; When bucket 5 lack of water, bucket lightens, and round steel lever 4 other ends lift, and alarm circuit is connected, and explosion-proof electric bell 1 is reported to the police.
Claims (2)
