Two stabilized pressure pumps used as the water supplementing pump can be alternately operated, the utility model solves the problem that a standby pump is laid up for a long time, the rustiness and the stop phenomena of the pump can occur, and the reliable operation of the water supplementing equipment can be ensured.
Description
The utility model belongs to the water supplement apparatus of boiler heating system, particularly relates to a kind of automatic control constant pressure supply water equipment of boiler heating system.
In the prior art, the constant pressure supply water equipment of boiler, be made up of diaphragm type nitrogen pressure jar, Pressure gauge, connecting line, gate valve, small pump, safety valve, magnetic valve, check-valves and electric control gear, Pressure gauge, small pump, magnetic valve are connected with electric control gear and controlled by it.Pressure gauge is an electro connecting pressure gauge, and long-term use can cause the galvanic corrosion and the adhesion of contact, has influenced the reliability of water supplement apparatus, and the life-span is low.Small pump is a stabilized pressure pump and a stand-by pump, and stand-by pump is on the shelf for a long time, and the corrosion stall can take place water pump, makes the water supplement apparatus cisco unity malfunction.
The purpose of this utility model provides a kind of new constant pressure supply water equipment, and it has eliminated manometric electric contact corrosion, and it is more reliable to work, and the life-span is longer.
To achieve these goals, the utility model has adopted following technical scheme: a kind of constant pressure supply water equipment, form by diaphragm type nitrogen pressure jar, Pressure gauge, connecting line, gate valve, small pump, safety valve, magnetic valve, check-valves and electric control gear, Pressure gauge, small pump, magnetic valve are connected with electric control gear, it is characterized in that described Pressure gauge is the teletransmission Pressure gauge.Described small pump is two stabilized pressure pumps that wheel changes jobs.
Advantage of the present utility model is as follows: the level pressure operating mode of using the water supplement apparatus of teletransmission gauge measurement heating system, replace the electro connecting pressure gauge that tradition is used, avoid the galvanic corrosion and the adhesion of electric contact, increased the reliability of water supplement apparatus, and can carry out the control of multiple spot pressure.Two stabilized pressure pump wheels as small pump change jobs, and have overcome the bad phenomenon of the long-term easy generation water pump corrosion stall on the shelf of stand-by pump in the past, have guaranteed the reliably working of water supplement apparatus.
The utility model is described in more detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model fundamental diagram.
As shown in Figure 1, this constant pressure supply water equipment is made up of diaphragm type nitrogen pressure jar 5, teletransmission Pressure gauge 8, gate valve 2, small pump 3,4, safety valve 11, magnetic valve 10, check-valves 12 and electric control gear 9.On the teletransmission Pressure gauge 8 pressure sensor is arranged, can carry out the control of multiple spot pressure.Small pump comprises two stabilized pressure pumps 3,4.Teletransmission Pressure gauge 8, two stabilized pressure pumps 3,4, magnetic valves 10 are connected with electric control gear 9, and controlled by it.Two stabilized pressure pumps 3,4 are taken turns and are changed jobs.Water supplement apparatus is connected by pipeline and softening water tank 1, circulating pump 6, boiler 7, and hot water delivery pipe and return pipe are arranged on the boiler 7, forms whole heating system.Utilize confession, the return water temperature of the heating system of this water supplement apparatus to be divided into four kinds: 95 ℃/70 ℃; 115 ℃/70 ℃; 130 ℃/90 ℃; 150 ℃/90 ℃.This water supplement apparatus is applicable to the middle-size and small-size heating system of 1.4-14MW.The nitrogen pressure jar belongs to a class GB150-1998.
The course of work of this water supplement apparatus is as follows:
In the running of heating system,, all will cause the variation of system water capacity and pressure, and directly influence the water level of nitrogen pressure jar 5 owing to reasons such as the variation of water temperature and pipeline leakages.Measure the water level of nitrogen pressure jar by the pressure sensor on the teletransmission Pressure gauge 8, can judge water capacity and water pressure in the heating system, and data are passed to electric control gear 9, electric control gear 9 control magnetic valve 10 and small pumps 3,4, thereby controlled the operating mode of system, made it to remain on operation in the safe range.The nitrogen pressure jar of this equipment is provided with five water level control points 13,14,15,16,17 in its range of stage, when dropping at 13, sends water level alarm signal, when water level is lower than at 14, the small pump automatic water supplement, when water level was raised at 15, small pump stopped automatically, when water level reaches at 16, magnetic valve cuts out automatically, when water level is raised at 17, and magnetic valve 10 automatic opening water discharges.Maximum changing range upper and lower limit in nitrogen pressure jar SEA LEVEL VARIATION is provided with the pressure auto alarm signal, and water level control point 13 is the low pressure alarming point, and alarm for high voltage is realized by alarm for high voltage point 18.
When heating system stops heat supply or power failure, intrasystem water cools off contraction gradually, or because pipeline leakage causes system's depletion, when water level reduces at 14, pressure sensor is passed to electric control gear with signal, control device is controlled small pump 3 or 4 automatically and is started moisturizing, and when water level was elevated at 15, small pump quit work automatically.When heating system begins heat supply, intrasystem water expanded by heating, the expansion water yield can be adjusted between the water level control point 15-17 in the nitrogen pressure jar.When the water level in the nitrogen pressure jar is raised at 17, teletransmission Pressure gauge 8 is passed to electric control gear with signal, electric control gear control magnetic valve 10 is opened automatically, the water row who has more in the nitrogen pressure jar is rushed down in the softening water tank 1, water pressure descends simultaneously, when water level rolled back at 16, magnetic valve cut out automatically, stopped draining.When water level dropped to once more at 14, small pump started draining automatically, and so circulation has guaranteed heating system safe operation under the level pressure operating mode.When the pressure in the nitrogen pressure jar surpassed the force value of alarm for high voltage point 18+2%, safety valve was opened quick draining, with pressure in the rapid reduction nitrogen pressure jar and the hydraulic pressure in the whole heating system, and the safe operation of assurance heating system.
