Description

Into and out petroleum single way valve of petroleum pump
The utility model relates to a kind of electric control equipment of high-floor feedwater equipment.
At present, high-pressure bottle low level water supply installation becomes the most promising equipment of high rise building water supply day by day.Mostly the water supply power system that matches with it is to adopt two or three water pumps now, mutual standby use, and mostly its electric controller is to adopt manual control and two kinds of forms of automatic control.Mostly advanced technology is to adopt pressure gauge with electric contact and control comparatively automatically, realizes many water pump alternate runs of control automatically.Comparatively product of the future is the supporting electric controller of the diaphragm type supercharging device of Baoding production, BKL type electric control cubicle.This device uses two pressure gauge with electric contacts, realizes the alternate run of many water pumps.But this kind automatic control water supply installation exists deficiency, and its controlling method is single, can not satisfy the use needs under multiple situation.Moreover, this device can not be controlled because in particular cases or accident occurs and make the motor frequent starting automatically, and rushing down that for example main water pipeline is a large amount of leaked, and causes water pump to supply water blindly, so that replace startup work between two pumps continually, thereby cause the damage of motor and equipment.
The purpose of this utility model is: a kind of multi-functional control water pump operation mode that has is provided, and the high rise building water supply electric controller of energy control of pump number of starts in the unit time.
Mainly by playing automatic change action and the autoconverter of remembering with time control function being arranged, control is from several methods of operation of line translation and the number of times that starts in the control unit time for the utility model.Its control signal source only depends on a pressure gauge with electric contact to finish.
Profile of the present utility model is control panel shown in Figure 1 surface.In the left side of control panel is operation monitoring, (F 1, F 2) open, stop tutorial light, (F for the first pump 3, F 4) be second pump start-stop tutorial light, (A 1, A 2) be first, second two pump operation standby current tables, (D 1, D 2, D 3, D 4) manually move control button for first, second two pumps.(W on the right side of control panel 1, W 2) be manual and automatic running state display lamp, (V) be monitor voltage table, (D 5) be reset button, (K 2) be manually and automatically to select driving switch, (D 6) be that automatic master partly makes button, (d 1, d 2, d 3, d 4, d 5) be that trouble location shows.Main switch (K), alarm bell scintillator (S) are housed in the outside of control panel.
Fig. 2 opens the back configuration state for control panel.Its left side is the rear view of control panel exterior view 1, on its right side (DK is housed 1, DK 2) automatic startup the air-break switch, (J of first, second two pumps 3, J 4, J 5, J 6, J 8) be midget relay, (J 1, J 2) be A.C. contactor (J 1-0, J 2-0) be contacts of contactor, (RJ 1, RJ 2) be that thermorelay, (Z) are transducer, (KO 1, KO 2, KO 3, KO 4) be transform device Operation Mode Selection button.
The utility model can be divided into following unit with control circuit (Fig. 3) from overall structure, starts running protection unit (Fig. 3 I), automatic converter unit (Fig. 3 II), memory time-delay control unit (Fig. 3 III), acousto-optic display unit (Fig. 3 IV).Has the manual control water pump operation from function; Automatically partly can be divided into first, second two pump alternate runs; The isolated operation of first pump; The isolated operation of second pump; First, second two pumps move simultaneously; Ultralimit starts autostop newspaper well; 7 kinds of functions such as trouble location demonstration, warning.
Start the running protection unit:
By J 1, RJ 1, D 1, D 2Form first pump startup running protection circuit, when with selector switch (K 2) pull manual orientation (K 2-1) after, press button switch K 2J 1Action, J 1-1Connect.J among Fig. 4 1-0Connection, first pump starting operation, tutorial light F 1Show.
Second priming of pump running protection circuit is identical with the first pump structure, when pressing D 4, J 2Action, J 2-1With J among Fig. 4 2-0Connect the operation of second pump startup, tutorial light F 3Show.
When pressing D respectively 1, D 3During button, J 1, J 2Discharge respectively, first, second two pumps are out of service respectively, the halt indicator F of first, second two pumps 2, F 4Show respectively.
Automatic converter unit:
Meet electric pressure gauge (Y), J by electricity 3, J 4, J 5, J 8, J 6, relief relay J 9, transducer (Z), method of operation control key (interlock switch) KO 1, KO 2, KO 3, KO 4Form automatic conversion circuit.
When with selector switch (K 2) pull to automatic position (K 2-2) after, press control switch (D 6), J 8Action makes automatic partial circuit conducting, automatic pilot lamp W 2Bright, promptly drop into operation automatically and prepare, can be by the following method of operation of convertor controls.
First, second two pump alternate runs: press KO 1, when Y table T=0, J 3Turn-on action, J 3-1Closure makes the first pump operation.While J 3-4Closure makes J 9Adhesive.Y table T=MKG(M can adjust according to actual needs when the first pump operation makes level pressure reach the high value) J 4Conducting, J 3Discharge J 3-1J 4-1Separation, J 1Discharging the first pump stops.When level pressure falls back to floors Y table T=0, because of J 9So adhesive is J 5Conducting J 5-1Closure makes the second pump operation, simultaneously J 5-4Separation, J 9Discharge.When the second pump operation makes level pressure reach high value T=MKG, J 6Conducting J 6-2Separate J 5Discharge; J 5-1, J 6-1Separate J 2Discharge the second pump and stop, back and forth realize first and second liang of pump alternate runs successively.
First pump isolated operation: press kO 2During key, KO 2-1Cut off J 6Path, KO 2-2Connect J 4, make J 3, J 4Directly connect two contacts of Y table, control J 1Action realizes the isolated operation of first pump.
