According to the traditional method of selection of centrifugal pump products mainly through the pump parameters, that is, head, flow and other parameters and the existing pump compared to select a pumping station with a relatively consistent pump conditions, and then according to The required parameters of the pump to determine the installation of the pump group elevation and other parameters. As its range of use increases, understanding of vertical pump power is even more important, with which we can not only understand the characteristics of the product, but also make better use of the product. Vertical pump power in unit time, the size of the work done by the machine is called power. Usually symbol N to represent. Common units are: kg · m / s, kW, horsepower. Usually the motor power unit is expressed in kilowatts; diesel or gasoline engine power horsepower expressed. Power machine passed to the pump shaft power, known as the shaft power, can be understood as the input power of the pump, pump power is generally referred to as the shaft power. Frictional resistance of bearings and packing; friction with water when impeller rotates; vortex of water flow in the pump, clearance backflow, inlet and outlet, mouth impact and other reasons. Inevitably consumes part of the power, so it is impossible for the pump to completely change the power input from the power machine into an effective power, of which there is a power loss. That is to say, the sum of the effective power of the pump and the lost power of the pump is the shaft power of the pump. Through the summary analysis of vertical pump power calculated as follows: power = flow × head × density × gravity acceleration / efficiency = flow rate (cubic / hour) × head (m) / 367 / efficiency Through the above analysis we can know The vertical pump power calculation includes several parameters of flow, lift, density and acceleration of gravity. With the development of vertical pumps, accelerating the research and promotion of these parameters is of great significance for the use and promotion of products. We all know that each product has its own parameters, through the study of its parameters can not only identify problems, but also for product reform and development to help. Manufacturers should pay attention to the relevant parameters of the research and attention. Related Articles: Single-stage pump selection Single-stage pump types and models Daquan
Led Grow Lights For Vegetables
What is Full spectrum led chip ?
It is the newest trend for indoor plants.Advanced LED Grow Lights chip,not provide sigle color ,provide broad spectrum 400nm~840nm , simialr with sun light ,but most is red and blue ,it is best for plant grow.This is a revolutionary step for LED Vegetation Lights which have previously been unable to act as the sole light source for the indoor garden. Suitable for all stages of plant growth.

Warnings:
1.lndoor use only.
2.To avoid being damaged,do not use water or drip irrigation while using.
3.Sunshine lighting time should be 12-18 hours.
4.While irradiating the plants,the height of led grow lamp is not less than 10 inches,
low height will cause the destruction of plants.
5.Highly hang the lamp will weaken the energy and affect the growth cycle of the
plants, so the lamp should not be hung too high.
6.While taking care of the plants, please spray the leaves and branches 2-3 times everyday,
to ensure the the plants do not wrinkle a wither, and have no phenomenon of few fruit, and
hard pericarp.
