Abstract

The utility model relates to an automatic controller for pressure pumps. The utility model is characterized in that a pressure relay is arranged on the top end of a first water pressure separating tube of a controller; a floating pillar is arranged in a second water pressure separating tube; coils of a control relay are arranged outside the second water pressure separating tube. The power supply of the pressure pumps is cut off by the pressure relay when the water pressure in a water supply pipe is high; the floating pillar in the second water pressure separating tube floats upwards when a tap is opened during the low water pressure, and thus, the inductance of the coils of the control delay is changed so as to switch on a pressure pump circuit so that the water is automatically pressed. Thus, the utility model is suitable for automatically controlling the pressure pumps of water nets in civil service or industrial service.

Description

Automatic controllor for pressure pump

The utility model relates to a kind of pump control unit, especially a kind of compression pump automatic controller.

Along with urban size constantly enlarges, population increases, produce constantly development, the water imbalance between supply and demand becomes increasingly conspicuous, causing from the beginning, the hydraulic pressure in the network of rivers descends, not only cause industry equipment water difficulty, family expenses automatic gas water heater even also can't use, the tap of fetching boiling water when serious does not have water to flow out at all, has a strong impact on production, life, and high residential building is all the more so.When people solved the low problem of above-mentioned hydraulic pressure, be to install compression pump additional to the water supercharging in the water pipe on running water pipe: compression pump was opened for a long time, then wasted energy, uneconomical, need not sometimes at all; If interim the unlatching will be known water pipe hydraulic pressure deficiency earlier, restart compression pump, so not only loaded down with trivial details, also extremely inconvenient.

The purpose of this utility model is to provide a kind of automatic controller that can open compression pump according to hydraulic pressure in the water pipe automatically.

The utility model is to realize above-mentioned purpose like this: be in charge of at first hydraulic pressure of this automatic controller and adorn a pressure relay; In second hydraulic pressure is in charge of, a floating post is arranged, there is the coil of control relay second hydraulic pressure branch tube outside; When the hydraulic pressure in the running water pipe arrived a certain setting value, the normally closed point of pressure relay disconnected, and cuts off the compression pump power supply, the pressurization air pump inoperative; When the hydraulic pressure in the water pipe during less than setting value, the tap if fetch boiling water this moment, current can make and be contained in the floating post of second hydraulic pressure in being in charge of and float, when floating post floats, the inductance that is contained in the outer coil of pipe changes, the control relay adhesive, its normal closure of making war, this moment, the normally closed point of pressure relay also was closed, so just connected the compression pump power supply, compression pump starts, and the water in the water pipe is pressurizeed, the pressure of pressurization back water enough backs down and is contained in the water plug in the water outlet and flows out, thereby has realized the purpose of this utility model.

As long as so open the arbitrary water tap that is positioned at behind the utility model, when hydraulic pressure was not enough, the utility model can start compression pump automatically to the water supercharging in the water pipe, and was convenient, practical, can be used for civilian tap water pipe network, also is applicable to the industrial network of rivers.

Below in conjunction with accompanying drawing the utility model is done concrete detailed description the in detail.

Fig. 1 is the utility model concrete structure figure;

Fig. 2 is the utility model application example figure;

Fig. 3 is an electrical schematic diagram of the present utility model.

With reference to Fig. 1, Fig. 2, the 15th, water intake, the 14th, water outlet, by them controller 12 is installed on the running water pipe, compression pump 11 is equipped with in the front of water intake 15, water tap 13 is arranged behind the water outlet 14, first hydraulic pressure of controller 12 is in charge of 16 top pressure relay 6 is housed, second hydraulic pressure is in charge of floating post 4 is housed in 17, and it can float with current, and second hydraulic pressure is in charge of 17 lower end, dress dividing plate 7 under the floating post 4, to prevent that floating post 4 from sinking, second hydraulic pressure is in charge of the coil 3 that 17 outer garden cylinder has control relay, in the wall body 1 of controller 12, directly over the floating post 4 threaded insert 5 is arranged, so that the floating post 4 of loading and unloading; Water outlet 14 perpendicular in the substantially horizontal part water plug 2 is arranged, cone 19 is arranged at the bottom of water plug 2, just in time cooperate with the conical surface 20 on the wall body 1, spring 10 is equipped with in the bottom of water plug 2, there is a upward silk cap 18 and a following cap 9 of adjusting spring 10 degrees of tightness the lower end of spring 10, and threaded insert 8 is equipped with in the lower end of following silk cap 9.

With reference to Fig. 3, ZJ ₁Be control relay, it has a normally opened contact ZJ _1A, ZJ ₂Be pressure relay (being 6 among Fig. 1) that it has two normally opened contact ZJ _2AAnd ZJ _2B, a normally-closed contact ZJ is arranged ₂₀, when tap water pressure during less than a certain setting value, ZJ ₂₀Normally closed, on the contrary then disconnect, cut off the entire circuit power supply; M is a compression pump, i.e. 11 among Fig. 2.

With reference to Fig. 1, Fig. 2, Fig. 3, the tap 13 of fetching boiling water, when the hydraulic pressure of running water pipe was lower than a certain setting value, current second hydraulic pressure of flowing through was in charge of at 17 o'clock, and floating post 4 is floated, and coil 3 inductance change, and electric currents change in the flowing through coil 3, control relay ZJ ₁Normally opened contact ZJ _1AClosure, this moment is low owing to hydraulic pressure, pressure relay ZJ ₂Normally-closed contact ZJ ₂C also is closed, so pressure relay ZJ ₂Energising, its normally opened contact ZJ _2A, ZJ _2BClosure, compression pump M(is 11 among Fig. 2) connect power supply and start, the water of running water pipe is pressurizeed; Water finishes when turning off water tap 13, because of floating post 4 does not have current not float, and ZJ _1ACan be not closed, ZJ ₂Can not connect power supply, compression pump M can not switch on, and does not work.When tap water inner pipe water pressure during greater than a certain setting value, pressure relay ZJ ₂Normally-closed contact ZJ ₂₀Can disconnect, cut off the entire circuit power supply like this, compression pump M can not start.The pressure of compression pump M pressurized water is determined by the degree of tightness program of adjusting spring 10, makes the pressure of water can overcome the pulling force of spring 10 and back down water plug 2, flows out from exporting 14.The adjusting of spring 10 tightness screws or unscrews realization by a last silk cap 18 and a following cap 9.
