Accompanying drawing explanation
The structural representation of gas controlling device before the pump that Fig. 1, Fig. 2 provide for the utility model.
Accompanying drawing illustrates:
1-water pump, 2-fluid passage, 3-liquid level gauge, 4-liquid level sensor, 5-exhaust-valve
Embodiment
Be clearly and completely described the technical scheme in the utility model embodiment below in conjunction with drawings and Examples, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, all belongs to the scope of the utility model protection.
As shown in Figure 1 and Figure 2, before this pump gas controlling device comprise be placed in fluid passage 2 path on and be positioned at the level monitoring assembly of the upstream of water pump 1.This structure is simple, practical, can gas flow in Real-Time Monitoring water, effectively prevents gas from entering water pump 1.
This level monitoring assembly also can comprise the liquid level gauge 3 on the path being placed in fluid passage 2, and inlet is set in the upper end of liquid level gauge 3, in the lower end of liquid level gauge 3, liquid outlet is set, and there is gas-liquid layering to make fluid flow in liquid level gauge 3 in the area of passage that the area of passage of liquid level gauge 3 is greater than fluid passage 2, preferably, also gas-liquid layering can be realized when fluid flows in liquid level gauge 3 with Peak Flow Rate.In addition, this level monitoring assembly also can comprise the liquid level sensor 4 be arranged on liquid level gauge 3, still can comprise the display be connected with liquid level sensor 4.
Wherein, the upstream that fluid passage 2 is being positioned at liquid level gauge 3 can form U-shaped water seal.As shown in Figure 2, fluid passage 2 is formed with U-shaped water seal in the upstream being positioned at liquid level gauge 3, can reduce entering of gas, avoids too much gas to enter into liquid level gauge.
If in the water in fluid passage 2 during entrained gas, when flowing through liquid level gauge 3, the area of passage due to liquid level gauge 3 is greater than the area of passage of fluid passage 2, then air-water mixture enters natural layering in liquid level gauge 3.Such as, when the internal diameter of liquid level gauge 3 is greater than the critical diameter of this air-water mixture air water laminar flow, the flows decrease of air-water mixture in liquid level gauge 3, the impact of gravity factor on two phase flow signals is greater than the impact of fluid frictional force, gas and the flowing of liquid natural layering, the top that gas is in liquid level gauge all the time because density is little, gas-bearing formation and water layer is formed in liquid level gauge 3, liquid level sensor 4 on liquid level gauge 3 detects the liquid level in liquid level gauge 3, by Signal transmissions to the display be connected with liquid level sensor 4, whether gas is there is according in the signal determination liquid level gauge 3 on display, be convenient to Real-Time Monitoring.
In addition, liquid level gauge 3 also can adopt transparent material to make, and by eye-observation, determines whether occur gas in liquid level gauge 3.
In above-mentioned embodiment, if there is gas through level monitoring component detection in fluid passage 2, can termination of pumping be discharged by gas, avoid gas to the destruction of water pump 1, but in water pump 1 actual moving process, termination of pumping, open pump complex procedures again, time and effort consuming, delays operation process.Therefore, can the gas exhaust piping be connected with the inside of liquid level gauge 3 be set at the top of liquid level gauge 3, and exhaust-valve 5 is set on gas exhaust piping.When there is gas in liquid level gauge 3, in time the gas in liquid level gauge 3 is discharged by gas exhaust piping by exhaust-valve 5.
The specific implementation process of gas controlling device before pump of the present utility model is described for the steam/water circulating process of the thermal store in solar-thermal generating system below.
Before this pump, the A end of gas controlling device can be connected with thermal store, as in solar-thermal generating system, by the heat storage of the part superheated vapor of heat collector in thermal store, superheated vapor is after thermal store heat interchange, form condensate water, under the supercharging of water pump 1, be delivered to mirror field and recycle.In this cyclic process, the normal operation of water pump 1 need be ensured, avoid the steam do not cooled completely to mix to condensate water or avoid the air in fluid passage 2 to enter into water pump 1.The condensate water of thermal store outlet enters into fluid passage 2 through A end, if be mixed into steam or air in condensate water, when flowing through liquid level gauge 3, internal diameter due to liquid level gauge 3 is greater than critical diameter during this air-water mixture air water layering, the flows decrease of air-water mixture in liquid level gauge 3, air water layering is formed in liquid level gauge 3, and the gas in liquid level gauge 3 is detected by the liquid level sensor 4 on liquid level gauge 3, as Fig. 1, shown in Fig. 2, the short transverse of liquid level gauge 3 is distributed with multiple electric contact, each electric contact is according to the SEA LEVEL VARIATION in liquid level gauge 3, make different responses, and this response signal is conveyed on display, according to the signal that display shows, the opening and closing of adjustment exhaust-valve 5.As display being provided with multiple signal lamp, along with the increase of gas in liquid level gauge 3, the liquid level of liquid level gauge 3 declines gradually, multiple signal lamps on display brighten gradually, now open exhaust-valve 5, in time the gas in liquid level gauge 3 is discharged, avoid gas to be mixed into water pump 1, affect the normal operation of water pump 1.
Obviously, under the prerequisite not departing from true spirit of the present utility model and scope, the utility model described here can have many changes.Therefore, all changes that it will be apparent to those skilled in the art that, all should be included within scope that these claims contain.The utility model scope required for protection is only limited by described claims.
