Abstract
The present invention relates to a middle opening single-stage and multi-stage double-suction turbine synchronous suction and discharge pump comprising a pump body and an automatic control system. The present invention is characterized in that a suction mouth of the pump body faces downward, the shaft line of a vertical middle opening surface supports on center. The top end of the pump body or the suction mouth of the pump body is provided with a draught fan, wherein an air suction port of the draught fan is communicated with a suction chamber of the pump body and the suction mouth of the pump body. The present invention can make the synchronous discharge and suction, namely, the water flows out as long as the machine is started up, and the pump is empty as long as the machine is stopped, which considerably extends the service life of the pump, and various heat insulation measures do not need to be used, which can save large amounts of expenses. The present invention has the advantages of high efficiency, large suction head, good electricity-saving effect, maintenance fee saving and construction capital cost saving. By using the pump of the present invention, self fill-up water absorption is not needed, and a higher factory building and a lifting device are not needed, and therefore, compared with the capital investment of each pump, the pump of the present invention can save about 1/2 capital investment.
Description
(1) technical field
The present invention relates to a kind of pump, particularly a kind of have a self-absorption function, and start is water outlet, and it is just empty to shut down pump, does not need the turbine synchronous discharging-suction pump of the measure that is incubated winter.
(2) background technique
At present, domesticly give, each enterprise such as draining field, drive the single-stage double-suction clean waterpump in the widely used mean level and do not possess self-absorption function in environmental protection, fire-fighting, oil, chemical industry, power station, metallurgy, pharmacy, city.Pump startup can only adopt the bottom valve water filling or adopt the vacuum pump diversion, and bottom valve easily leaks, poor reliability, and the vacuum pump air displacement is little, and starting time is long, and need have the insulation measure winter.When the pond was dark, general double suction pump was inhaled journey and is not reached, and must dig the low level pump house or build head-tank, the capital cost height.Adopt submersible pump, Under Water Pumps, general self-priming pump all to have different shortcomings separately with diagonal pumps, as:
1. driving the single-stage double-suction pump in the mean level can only adopt the bottom valve water filling or make pump startup, proper functioning with the way of vacuum pump diversion.Bottom valve is unreliable, in case fine particle in the liquid or foreign material are stranded in the bottom valve, will cause bottom valve to leak, and pump can't start.The vacuum pump diversion time is long, and need take the insulation measure winter, the capital cost height, and flow surpasses 10000m
3/ h, the pump suction head can only reach 3.5m, must build low level pump house or head-tank, thereby has sharply dwindled the using scope of this pump.
2. submersible pump seals rapid wear, motor water inlet rapid wear, and the cable joining sealing is bad, motor short circuit, maintenance difficulty.
3. Under Water Pumps guide bearing rapid wear causes bearing running hot, and unit vibration can not be worked pump, maintenance lifting height height, and the repair apparatus cost is expensive, the recondition expense height.
4. general self-priming pump narrow application range, flow is no more than 5000m
3/ h, self-priming time is long, and efficient is low by 8～10%, and power consumption is big.
5. vertical diagonal flow pump, the cost height, maintenance is inconvenient, the expense height, unit weight is big, the capital cost height.
(3) summary of the invention
Purpose of the present invention, it is big to provide a kind of self-priming height, and start is water outlet, and it is just empty to shut down pump, does not need the insulation measure winter, opens the double-suction turbine synchronous discharging-suction pump in the little level of floor space.
The technological scheme that adopts is:
In open the double-suction turbine synchronous discharging-suction pump, comprise pump and automatic control system.Its technological points is that Pump Suction Nozzle is downward, and vertical centering control is opened face, and pump discharge can be upper outlet or a left side exports, right outlet.The present invention comprises that also pump changes to intermediate support by the pin support, and this change mainly is to reduce the pump setting height(from bottom), improves the suction journey of pump.Another technological points of the present invention is on the pump top or the Pump Suction Nozzle place is provided with turbine blower fan or general blower fan (single-stage, multistage).The intakeport suction port corresponding with pump chamber of turbine blower fan or general blower fan communicates.On the top of pump or pump chamber and suction pipe place bleed valve that an automatic or manual is set communicate with atmosphere.
During start, the turbine fan starting vacuumizes, and produces negative pressure; when suction pipe and pump chamber internal pressure were lower than atmospheric pressure, the low level medium entered suction pipe and pump chamber under atmospheric pressure; reach more than the impeller center line, the pump proper functioning of driving automatically to drop into, this moment turbine blower fan autostop.During termination of pumping, automatic or manual is opened bleed valve, and pump chamber and suction pipe are communicated with atmosphere, and medium comes off under atmospheric pressure automatically, makes pump chamber and suction pipe become empty, starts identical with said process once more.
The present invention has following advantage:
1. reach synchronous row and inhale, promptly start shooting, shut down just sky of pump, make pump have self-absorption function with regard to water outlet.Because it is just empty to shut down pump, so there is not static erosion problem in pump, prolonged the working life of pump greatly, and need not adopt various insulation measures winter, can save a large amount of funds.
2. efficient height, suction head is big.Present device efficient reaches 86.5%, at Q=10000m
3When/h is above, inhale about Cheng Tigao 2.0m than general middle-opening pump.
3. power savings is good, and the present invention improves 8～10% than Under Water Pumps, general self-priming pump efficient.
4. saving maintenance cost.Pump of the present invention, the repair and maintenance expense only is 1/5 of a conventional pump.
5. save capital cost is installed.Adopt general middle-opening pump, build head-tank or low level pump house; Adopt Under Water Pumps, have between higher tool car and lifting means, capital cost is higher, and the capital cost that has exceeds several times than pump valency, even tens times.Adopt pump of the present invention, do not need the self filling type suction, also do not need higher factory building and lifting means, therefore saving about 1/2 at least than above-mentioned each pump on the capital investment.
