The utility model discloses a set up the pressure of buffer tank in to the pipeline and carry out the invariant and adjust, energy -conserving, environmental protection in addition, simple structure, the practicality is strong, is fit for application promotion on a large scale.
Description
Technical field
This utility model relates to a kind of supply equipment, is specifically related to a kind of non-negative pressure frequency-changing water supply device.
Background technology
Supercharging water supply system of the prior art uses constant pressure water supply pattern mostly, realize energy-conservation by converter regulation pump rotary speed, but its Energy-saving Situation does not still reach perfect condition, this is because actual application have ignored a problem, that is exactly that user is far smaller than design discharge the water consumption major part time, this allows for water pump and is in low-frequency operation state for a long time, causes water pump efficiency to be substantially reduced, and power consumption increases.
Utility model content
The purpose of this utility model is that provides a kind of non-negative pressure frequency-changing water supply device to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
This utility model includes feed pump, surge tank and booster pump, the port of export of described feed pump is connected for water end (W.E.) with user, described feed pump is connected with the first entrance point of described surge tank, described booster pump is connected with the second entrance point of described surge tank, and the port of export of described surge tank is connected for water end (W.E.) with described user.
Specifically, regulation valve, described regulation valve and the pressure transducer linearly connected being arranged on pipeline it are provided with between described surge tank and described booster pump.
Further, described user arranges check (non-return) valve on water end (W.E.).
The beneficial effects of the utility model are:
This utility model carries out constant regulation by arranging surge tank to the pressure in pipeline, and energy-saving and environmental protection, simple in construction, practical, it is suitable for large-scale application.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1-booster pump, 2-regulates valve, 3-pressure transducer, 4-feed pump, 5-surge tank.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1, this utility model includes feed pump 4, surge tank 5 and booster pump 1, the port of export of described feed pump 4 is connected for water end (W.E.) with user, described feed pump 4 is connected with the first entrance point of described surge tank 5, described booster pump 1 is connected with the second entrance point of described surge tank 5, and the port of export of described surge tank 5 is connected for water end (W.E.) with described user.At this moment the water redundance that water pump is got enters into surge tank 5 and stores, when surge tank 5 water storage reaches design pressure, VFC water pump is out of service, at this moment user turns and is laid in water by surge tank 5 and meet and use, and reaches to improve water pump efficiency and energy-conservation purpose with this.
Being provided with regulation valve 2, described regulation valve 2 and pressure transducer 3 linearly connected being arranged on pipeline between described surge tank 5 and described booster pump 1, when hypotony in pipeline, the aperture that can adjust regulation valve 2 increases the pressure in pipeline.
Described user arranges check (non-return) valve on water end (W.E.), prevents water from pouring in down a chimney and causes the pump housing to damage.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, should be included in protection domain of the present utility model.
Claims (3)
