No secondary negative pressure water supply equipment working principle diagram and the technical process characteristics

No secondary negative pressure water supply equipment working principle diagram:

no secondary negative pressure water supply equipment for the microcomputer automatic control frequency control of motor speed operation, power equipment, automatic stop calls automatically boot, fully automatic, USES no negative pressure ( The overlying) The secondary water supply technology, make the secondary water supply equipment more intelligent, energy saving, and reliable.

1, no negative pressure water supply equipment using the multi-stage stainless steel pump, pump casing, impeller and main parts are made of food grade stainless steel mass flow is smooth, high efficiency and energy saving, stable running, the noise is very bottom, the machine performance, is the ideal green environmental protection energy-saving water supply equipment.

2, booster no negative pressure water supply equipment without having to build tank or water tank, also do not need to set up a large pressure tank, saves a large amount of investment, and because the tap water pipe network pressure itself can be fully used.

3, health, no pollution, water supply system from tap water pipe network to the user the faucet is fully enclosed structure. Pollutants will not enter the system, not direct contact with air, water filtration components made of food grade stainless steel no secondary pollution, environmental health.

4, energy-saving effect is significant, the equipment directly with water pipe series, a water supply pipe network pressure in water plant, on the basis of the superposition of the required pressure difference how many, how much, can make full use of the pipe network pressure, water resources, don't even need to run the equipment, and the traditional water supply equipment, energy saving up to 30% 90%

5, save water, not regular cleaning and disinfection, no waste of water resources and human resources. Save maintenance cost.

no secondary negative pressure water supply equipment specifications:

1, water flow rate 0 - 1500 M3 / H head

0. 2, the control motor power 75 - - - Water supplies to 1500 kw

3, number 10 - 10000

4, pressure control range 0. 15 - 1. 6 mpa

5, the average energy saving rate of 30 - 60%

6, the control principle of sinusoidal PWM and space vector SVPWM

7, the operation mode of single pump or pump automatically switches

8 programmable control manner and the PID control

9 150% for 60 seconds, overload capacity

10, soft start, the overvoltage protection, lack of phase, a disguised form, undervoltage, open circuit, instantaneous power, short circuit and so on all have self-diagnosis display and protection function.

no negative pressure technology characteristics of the secondary water supply equipment specifications introduction:

WHG - 37 m3 - PF for example is as follows:

WHG - - - Equipment model ( Microcomputer control constant pressure water supply equipment)

37 - - - Control of water pump motor rated power ( 千瓦)

M - - - Common way to start the pump power frequency ( C - - - Y- J - three step-down starting way - - Since the coupling step-down starting way)

3 - - - Control the main water pump number ( 1 - 7)

p - - - Fixed works ( X - - - Circulation way, empty - - - A variable frequency)

F - - - Have assisted small pump ( Empty - - No small auxiliary water pump)

6, cover an area of an area small, with no negative pressure water supply equipment do not need to build a tank or water tank do not need to configure a large pressure tank, greatly saving the system covers an area of, can use to save land for improving the utilization ratio of real estate, in line with the requirements of national land saving.

7, installation is simple, just connect in and out of the water pipe, short construction period, simple installation.

8, steady running, small vibration, low noise, Noise value is less than 50 db) 。

9, stable water supply system, the pressure at the ends of guarantee system.

J&T INDUSTRY CO.,LTD. thinks that that firms can avoid the artificial choice between quantitative and qualitative risk management, allowing both to play important roles in surfacing and assessing risks.
