Abstract
The utility model relates to a set of water pumping devices which comprises vacuum pumps, negative pressure storage tanks and control units. The utility model can be widely used for the construction works of various civil engineering. The utility model has the advantages of energy saving and long service life. The utility model is an ideal replacing product which can replace the jet pump of present use.
Description
The utility model dependent territory is built the construction special device.
At present in the civil engineering of China, because the level of ground water of some areas is higher, when excavating cubic metre of earth and be lower than every construction on the face of land (as the under ground portion of every building, laying of underground utility and passage or the like), all need to carry out simultaneously well-points dewatering (or claiming ground precipitation) and construct.The underground water in area extracts so that will construct, and makes that construction is normally carried out.In this construction, a large amount of employings is the equipment of a kind of being called as " Jet injector " at present, its structure is seen figure (), its working principle is the extracting effect that utilizes high-velocity flow to produce in liquid jetting device, discharge after underground water is evacuated to ground, yet this equipment is because its working principle has just determined itself to have following shortcoming: see figure one
1, power consumption is big: because the required high-velocity flow of Jet injector, rely on high powered water pump to produce, with regard to the Beijing area, each unit in charge of construction adopts 7.5 kilowatts/hour centrifugal water pumps more, but is same as the difference of construction region, and the distribution of groundwater run off also can be different, and Jet injector is certainly in the power consumption aspect, can't do corresponding adjusting according to the difference of actual conditions, so that a large amount of valuable electric energy has slatterned with the form that flogs a dead horse
2, easily loss: because the existing underground drinking-water pipe that uses simultaneously with Jet injector, filtration to silt is unsatisfactory, so having part silt sometimes is entrained in the water pump by current, the water pump vane of these silts and high speed rotating produces friction, sometimes also can be to pump case, axle and various sealing material produce wearing and tearing, thereby have increased maintenance workload and difficulty the working life of having reduced equipment.
The noise that produces when 3, large pump turns round also can pollute surrounding environment.
The purpose of this utility model, provide a kind of dependence vacuum pump and produce the phreatic device of negative pressure suction force extracting, and this purpose will realize by following technological scheme, the working principle of this device is seen figure (two), it is mainly by vacuum pump (1), negative pressure basin (2) and control unit (3) three parts are formed, and the effect of its intermediate pump is for whole system produces negative pressure, and the effect of negative pressure basin is the underground water that temporary transient storage is pumped down to ground.Control unit then is to be used for the opening and stop of vacuum pump, and opening and closing automatically of basin top and bottom portion solenoid valve controlled (concrete technological principle is seen embodiment) and seen figure two
The utility model is compared with existing Jet injector, and the advantage that has is:
1, saving power calculating and real side show that the groundwater discharge that needs the precipitation area is as being not more than 20 meters
3In/time,, (this numerical value in actual each building site was all less than 5 meters
3/ time), then only needing air displacement is that 8 liters/second vacuum pump gets final product, power consumption only be 750 watts/time, add this device and can adopt service intermittent, then economize on electricity is at least more than 80%, the more important thing is the difference that this device can distribute with construction region and groundwater run off, opens and regulate voluntarily, stop frequency, when the underground water yield was big, basin can be taken out full water in very short time, began the next round circulation after the discharging rapidly, thereby accelerated frequency of okperation, when the underground water yield hour, basin can need just be filled water for a long time, thereby has slowed down frequency of okperation, and frequency of okperation is fast and slow, and this device all can keep enough negative pressure suction forces to underground water.
2, reduce wearing and tearing: only entered basin and do not enter vacuum pump owing to draw up the water that comes, thereby can not produce wearing and tearing, thereby prolonged the working life of device widely to pump.
For every usability of making this device is more perfect, we also design is equipped with every accessory, as anti-adverse current one-way valve (4); Pressure vacuum gauge (5) and support (6) etc.
Embodiment: when electric current is switched on, on the basin, following two solenoid valves (7) and (8) will be closed, vacuum pump entry into service simultaneously, at this moment basin will be in negative pressure state gradually, and underground water can enter basin by pipeline, along with the work of vacuum pump, the water yield in the basin can increase gradually, when the water yield reached fluid level controller, control unit can cut off vacuum-pump power supply, opened solenoid valve (7) and (8) simultaneously, outwards discharging of water in the basin at this moment, when discharging finished, control unit can restart vacuum pump again, and closes (7) and (8) two valves simultaneously, next round was drawn water to circulate and was begun this moment, and went on and so forth.
More extensive for the zone that this device is suitable for, its vacuum pump needs certain air displacement, is 4 liters/second-8 liters/second, power be 550 watts/time-750 watt/time, negative pressure basin specification is diameter 300mm-1000mm, high 500mm-1500mm, for ease of maintenance, the tank top is that flange-type binds, and the bottom then is made into funnel form, the connecting line between vacuum pump and basin, can adopt iron or steel pipe, caliber is 5-50mm, and length is 0.5-3 rice, and the solenoid valve latus rectum is 5-50mm.
Aspect the manufacturing, except that the negative pressure basin belongs to the special pressure container, other parts are seriation in China, standardization is so maintenance or replacing are all very convenient, because this device has efficiently, energy-conservation characteristics in case apply, will be brought considerable economic to country.
This device can be by all kinds of amateur manufacturer production, and producer also can combine this device of the different size that forms a complete production network with the vacuum pump of different size with not isometric basin according to the difference of user's request.
