Detailed description of the invention
For the benefit of the understanding to structure of the present utility model, illustrates below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the double high-pressure pump counter-infiltration system of this utility model.Shown in Fig. 1,
This utility model provides a kind of double high-pressure pump counter-infiltration system, including: the reverse osmosis feedwater being sequentially connected with
Case 1, reverse osmosis feedwater pump 2, filter 3, double high pressure pumping apparatus 8, reverse osmosis unit 6 and reverse osmosis produced
Water tank 7.
Described pair of high pressure pumping apparatus 8 includes that first high-pressure pump branch line the 9, second high-pressure pump branch line 10 and string set
Branch line 11, described first high-pressure pump branch line 9 and the second high-pressure pump branch line 10 be arranged in parallel, described first high pressure

Further, described filter 3 is cartridge filter.
Hereinafter the concrete application specific details of double high-pressure pump counter-infiltration systems that this utility model provides is carried out in detail
Explanation.
When Summer Precipitation is many, when reverse osmosis unit water inlet TDS is low, reverse osmosis unit reaches to produce discharge
Desirable pressure is low.Only need Open valve a, b, close valve c, d, e, start a high-pressure pump 4 high
Frequency runs, and another high-pressure pump 5 can do standby.(or Open valve c, e, close valve a, b, d,
Starting high-pressure pump 5 high frequency to run, another high-pressure pump 4 can do standby)
When inwelling in winter, during reverse osmosis unit water inlet TDS height, reverse osmosis unit reaches to produce discharge
Desirable pressure is high.Open valve c, b, d, close valve a, e, starts two high-pressure pump 4 and 5 strings
Through transport row, promotes system intake pressure, to meet system needs.
Low at feed water by reverse osmosis TDS, only need to play a high-pressure pump and i.e. can reach system when producing discharge.If
During because needing use water the most in a large number by water factory district's special circumstances, also can Open valve a, b, c, e, pass valve closing
Two high-pressure pumps 4,5 are all started, parallel running by door d, improve reverse osmosis unit inflow,
Reach to increase the purpose of water flow.
The coastal area inwelling time is shorter, in 1 year at most of the time reverse osmosis unit water inlet TDS
Needed for relatively low state, reverse osmosis unit, intake pressure is relatively low.According to a high-lift high-pressure pump, high
Press pump is chronically at low-frequency operation.According to double high-pressure pump equipment, reverse osmosis unit water inlet TDS low time
Between only use a high-pressure pump high frequency to run, be to enable two again when inwelling causes raising into water TDS
High-pressure pump series operation.Double high-pressure pump equipment should in inwelling water recharging water system reverse osmosis unit
With advantages, main efficacy results is as follows:
The application beneficially energy saving of system of double high-pressure pump equipment subtracts consumption, and environmental benefit highlights.Because of high-lift height
When press pump is chronically at low-frequency operation, it is more that pump operation deviates its declared working condition point, causes the operation of pump to be imitated
Rate is relatively low, and energy consumption is bigger.And using double high-pressure pump equipment, the most of the time of reverse osmosis unit is in one
Platform low lift high-pressure pump high frequency runs, and pump operation is close to specified industrial and mineral point, and the efficiency of pump is higher, is conducive to joint
Consumption can be subtracted.
The application of double high-pressure pump equipment can reduce equipment failure rate, beneficially system operation maintenance and equipment to be made
With the raising in life-span.High-lift high-pressure pump is chronically at low-frequency operation, is not at its normal operation range,
High-pressure pump motor and frequency converter failure rate can be caused to increase, cause the system stability controlling the water circulation time to reduce, run
Maintenance cost increases.Using double high-pressure pump equipment, the most of the time of reverse osmosis unit is in one and low raises
Journey high-pressure pump high frequency runs, and pump is in its normal operation range, high-pressure pump motor and frequency converter failure rate
Reduce.
Double high-pressure pump equipment are conducive to system stable operation.Double high-pressure pump equipment, two high-pressure pumps can be each other
Standby.If wherein a high-pressure pump breaks down, another high-pressure pump changeable uses, fault high-pressure pump
Can processed offline, do not affect system run.
Double high-pressure pump equipment can tackle emergency situations.If being badly in need of a large amount of water with water spot, double high pressure can be enabled
Two high-pressure pump parallel runnings of pumping unit, increase the inflow of system, and then increase system product water, should
To emergency situations.
This utility model provides a kind of double high-pressure pump counter-infiltration system, by the first valve, the second valve,
The corresponding switching of the 3rd valve, the 4th valve and the 5th valve, two high-pressure pumps get final product series operation,
Also can parallel running, two high-pressure pump Yang Cheng sums are equal with a former high-pressure pump Yang Cheng, every high-pressure pump
Exert oneself and a former high-pressure pump is exerted oneself identical, when solving single high-pressure pump low-frequency operation, water pump deviation volume
Determining operating point operation causes efficiency to reduce, and energy consumption increases, and is unfavorable for energy saving of system, and long-term low frequency fortune
Guild causes the problem that pump motor and frequency converter failure rate increase.Therefore, this pair of high-pressure pump reverse osmosis system
System has effect that is efficient, energy-conservation and that reduce system failure rate.
Above in association with accompanying drawing embodiment, this utility model is described in detail, ordinary skill in this area
This utility model can be made many variations example by personnel according to the above description.Thus, some in embodiment
Details should not constitute restriction of the present utility model, and this utility model will define with appended claims
Scope is as protection domain.
