Potassium sulfate is a common potash fertilizer. It can improve crops ability of drought resistance, cold resistance, lodging resistance,and pest disease resistance. It can also promote flowering and fruiting, and better use of nitrogen to increase protein content, and promote the production of sugar and starch. Especially suitable for tobacco, sugarcane, potato, sweet potato, grape, tea tree and other high potassium crops and sulfur-like cruciferous crops (such as rapeseed, beans, etc.) .Increase the strength, fineness,color purity of cotton and hemp crop fiber.

Potassium sulfate must be combined with nitrogen and phosphorus fertilizers for fully effect.
1. Do not apply to the roots of crops, neither to stems and leaves.
2. Not recommended for use in paddy fields or soil with strong reduction
3. Must be applied with lime or calcium magnesium and phosphate fertilizers for long-term application on the acidic soil.
4. Better to apply in small amount or mixed with farmyard fertilizer for sandy soil.
5. Prevent rain and damage during storage and transportation.

LGThe automatic high-rise heating vector pressure regulating water supply equipment has the function of variable flow, first, dissipate the external network traffic, pressure changes, the unit automatically adjusts to ensure high area system water flow. The same pressure.
Second, when the demand for system traffic in the high zone changes due to user sub-metering and other reasons, the unit automatically adjusts the heating flow while the backwater is consistent with the external network. In this way, no matter how the traffic is changed, it can be fully ensured that the backwater in the high zone has no impact on the low zone, ensuring normal and safe operation in the low zone, more energy-efficient and low-carbon, and lower running costs.
Low investment cost
Unattended
run smoothly
easy installation
Small footprint, high degree of automation
Heating the high-rise buildings in the basement complex
For the terrain elevation is too large mountain temple building height heating
Thermal power plant coal warehouse heating
                                      Features
High efficiency and energy saving, constant pressure of water supply, complete functions, programming control, reliable operation, simple operation, perfect protection function, long service life and strong anti-interference ability.
                     Applications
Urban and rural water pumping stations, gas stations, residential areas, hotels, restaurants and other large public buildings living water and fire water.

                         principle
The pressure sensor or flowmeter will be converted into electrical signals into the automatic control box, the signal through the automatic control box after the operation feedback to the inverter, the inverter by changing the frequency to change the motor speed, so as to change the pump at any time, will be the operation of Constant water pressure at a certain point to be determined, and the flow rate according to the size of the water changes, not only to achieve energy saving, but also safe and reliable.
The device is the parallel connection of multiple pumps, when the water consumption is less than or equal to a single pump working flow, the variable frequency pump starts to work, the water consumption gradually increases beyond the single pump working flow, the power frequency pumps have been put into operation, while the variable frequency pump Play a trace role in regulation. When the amount of water is gradually reduced, one by one to stop working frequency pumps, until the variable frequency pump.
The unit is also equipped with a pressure pump or pressure tank, when the amount of water is very small, the pressurized water stored in the pressure tank or pressure pump to provide pressure water to maintain the system, variable frequency pump to stop working, its energy saving effect is better.
The unit is composed of one to four main pump, a constant pressure pump (or pressure tank), water mains, valves, automation instruments, automatic frequency conversion control box and so on, so it is easy to install and compact. Ex-factory rigorous testing, stable performance.
