Description

Auxiliary pressurizing device of fluidic pump

The utility model provides a kind of jet pump to assist water booster system, is useful in high-rise building and needs to utilize in the water supply system water booster system of secondary pressurization pressure in the water supply network with energy efficient and keep fully satisfying the device of water supply requirement.

In the prior art, because it is very outstanding that the urban skyscraper thing increases water supply problem year by year, present most high building all adopts usually earlier the water in the pipe network to be injected in the storage cistern that is arranged on basement and raises in the roof high level cistern to supply with the way that full building uses with water pump, its shortcoming is that original head pressure can not obtain utilizing the pump head higher-wattage that is adopted big thereby how quite uneconomical power consumption is in the pipe network, and the easy dissipation of chlorine in the water." microcomputer control automatic speed regulation water supply facilities " that ground such as Shenyang, Jinzhou provides then need not be provided with high level cistern and can not utilize ductwork pressure too, in the water ebb or not during water,, the constant voltage water pump that keeps system consumes unnecessary electric energy for must keeping certain rotating speed.Utility model " building supply device " (patent No. CN87211155U) need be provided with pressurized tank between water pump and pipe network in addition, because pressurized tank generally can not be done to such an extent that very big its volume is very limited also often can not fully satisfy the water supply needs.

The purpose of this utility model provides the auxiliary water booster system of a kind of jet pump, and it is to increase by one group of jet pump to make energy efficient keep the fully device of feedwater with the pumping capacity of utilizing the most pressure head auxiliary water pump in the pipe network as far as possible between high-rise building underground storage tank outlet pipe and pressure pump.

The utility model provides the auxiliary water booster system of a kind of jet pump to be useful in the device that utilizes ductwork pressure fully to satisfy water supply requirement with energy efficient and maintenance in the water supply system that needs the secondary pressurization, it is by the pipe network inlet channel that total water valve and metering water meter are housed substantially, the storage cistern ［ 3 ］ of float valve ［ 2 ］ is housed, being provided with the high level cistern that the outlet conduit of pressure pump ［ 6 ］ and outlet conduit lead to the building top forms, it is characterized in that: a, described water storage tank ［ 3 ］ is provided with flap valve ［ 4 ］ on the outlet pipe that its adjacent bottom is adorned, be provided with jet pump ［ 5 ］ between outlet pipe of drawing behind the process flap valve ［ 4 ］ and the pressure pump ［ 6 ］; Nozzle ［ 12 ］ rear end in the middle of b, its suction chamber of described jet pump ［ 5 ］［ 11 ］ is connected with the water inlet pipe ［ 10 ］ on the pipe network, suction chamber ［ 11 ］ joins with the water pipe that enters pressure pump ［ 6 ］ through the anemostat ［ 14 ］ of mixing tube ［ 13 ］ on the same center line in nozzle ［ 12 ］ the place ahead, then is connected with the suction pipe that passes to suction chamber ［ 11 ］［ 15 ］ through the outlet pipe of drawing behind the flap valve ［ 4 ］.The installation site of its described water-jet pump ［ 5 ］ should be as far as possible near storage cistern ［ 3 ］, and with pressure pump ［ 6 ］ between need leave and mix the long water pipe that spreads usefulness.Its described pipe network inlet channel is provided with electromagnetic valve ［ 1 ］ before the import that enters storage cistern ［ 3 ］, electromagnetic valve ［ 1 ］ is synchronoused working with pressure pump ［ 6 ］, electromagnetic valve ［ 1 ］ cuts out when pressure pump ［ 6 ］ turns round, and when pressure pump ［ 6 ］ when stopping electromagnetic valve ［ 1 ］ open.

The utility model compared with prior art, because it adopts jet pump to connect with water pump, can utilize partial pressure head in the pipe network, improved the intake pressure of water pump, that is the auxiliary pumping capacity that has increased water pump improves its lift that pumps up water, reduce thereby make water pump use power to reduce power consumption, reach the purpose (energy-conservation) of energy efficient about 10%～60%.And do not violate water-supplying unit and generally do not allow directly, the unlikely abrupt pressure reduction that causes the neighbouring area pipe network problem of other unit and resident family's water on every side that exerts an influence by the regulation of drawing water in the pipe network.Because pipe network is directly taken from the water source in the jet pump that is adopted in the nozzle, chlorine dissipation is few, and its jetting amount accounts for half of total inflow or quite most, helps keeping the water cleaning health.

Embodiment: on top the adjacent bottom outlet pipe of basement water storage room ［ 3 ］ of float valve ［ 2 ］ being housed as shown in Figure 1 water outlet only is installed and the flap valve ［ 4 ］ that can not intake, installing one group of jet pump ［ 5 ］ between outlet pipe that flap valve ［ 4 ］ is drawn and pressure pump ［ 6 ］.Nozzle ［ 12 ］ rear end in the middle of the suction chamber ［ 11 ］ of jet pump ［ 5 ］ is connected with the water inlet pipe ［ 10 ］ that the pipe network inlet channel is branched out.The pipe network inlet channel that is provided with total water valve and metering water meter is bifurcated into two tubes after pressure meter, its another pipe enters storage cistern ［ 3 ］ top and is provided with the electromagnetic valve ［ 1 ］ of being synchronoused working with pressure pump ［ 6 ］ by the automatically controlled circuit manipulation in import department, and moisturizing makes storage cistern often be in full water state successively.The pipe network inlet channel that has pressure makes the nozzle ［ 12 ］ of jet pump ［ 5 ］ be in the jetting state always, the water that can ceaselessly use the water in this barrel also suction chamber ［ 11 ］ to be full of is all the time taken away in the water inlet pipe that is injected into pressure pump ［ 6 ］ jointly and is pumped up water, expired till its liquid level relay shows that signal closely makes pressure pump ［ 6 ］ termination of pumping until roof high level cistern middle water level, can keep sufficient and continuous self water feeding.

Embodiment two, its basic structure is with accompanying drawing 1 embodiment as shown in Figure 2, in addition on the pipe network inlet channel by adorn a multidigit pressure switch ［ 7 ］, on storage cistern ［ 3 ］ outlet pipe by adorning an adjustable speed water pump ［ 8 ］, going up set about 5～6 different water pressure numerical value correspondences contacts by pressure switch ［ 7 ］ with automatically controlled circuit respectively by speed Control case ［ 9 ］ therebetween adjustable speed water pump ［ 8 ］ rotating speed is handled adjustment.(be assumed to 1.5Kgf/cm when for example pipe network water pressure is the minimum stage value ²) should make adjustable speed water pump ［ 8 ］ rotating speed reach maximum value also can to obtain H-Max, and (be assumed to 4Kgf/cm during for maximum Stage Value at pipe network water pressure ²) should make adjustable speed water pump ［ 8 ］ speed drop to zero-bit termination of pumping just.By jet pump ［ 5 ］ under big hydraulic head direct attack to pressure pump ［ 6 ］ pumped up water by another flap valve ［ 4 ］ through by-pass line this moment, its middle each set contact in turn corresponding matching.Jet pump ［ 5 ］ can be changed with ductwork pressure obtain necessary lift and to export enough flows, not only energy efficient but also can guarantee abundant feedwater.

Embodiment three, as shown in Figure 3 but the equal nozzle ［ 12 ］ by jet pump ［ 5 ］ of the current of its pipe network inlet channel, the water pump ［ 16 ］ of pressurization uses frequency conversion speed adjusting pump, the inflow of pipe network is greater than the pump-out of water pump ［ 16 ］ when the low discharge state, and the part current in the pipe network can backflow via suction pipe ［ 15 ］ inlet of jet pump ［ 5 ］ suction chamber ［ 11 ］ and enter storage cistern ［ 3 ］ along upright flap valve ［ 4 ］.And when water pump ［ 16 ］ pump-out during greater than the inflow of pipe network, the current of storage cistern ［ 3 ］ are inhaled in the jet pump ［ 5 ］ by flap valve horizontal on the outlet pipe of bottom ［ 4 ］ and enter water pump ［ 16 ］ jointly and raise in the system of building and supply water, and so circulation is carried out.
