IHW horizontal pipeline chemical pump is water pump and water-filled three-phase asynchronous motor to irrigation and drainage equipment. QS submersible pump produced by our company is qualified to implement JB / T8092-2006 and production of products, the national industrial production License number: XK06-216-02138. Has the advantages of small size, light weight, easy installation and maintenance. Not only for farmland irrigation, flower sprinkler, but also for the city, the left mine water tower. Safe and reliable operation, energy efficient , Is an ideal water lifting equipment.
Second, IHW horizontal pipeline chemical pump conditions of use:
1, the voltage is 380V (± 10%), the frequency is 50HZ three-phase AC power.
2, the water is generally non-corrosive water, PH value of water pH 6.5-8.5, sand content less than 0.024% (weight ratio), the water temperature is not higher than 40 ℃, excluding oil.
3, electric pump installation should be upright, not lying down installation.
4, according to the height of the pumping water and the diameter of the selection of electric pump, so that the pump in a relatively high efficiency range of operation, the general provisions of the flow rate of 0.7-1.2 times the scope of use.
5, electric pump must be completely immersed in the water work, the normal working hours in the water level 0.5-1 meters.
Third, IHW horizontal pipeline chemical pump structure principle IHW horizontal pipeline chemical pump consists of two parts: the pump and submersible motor. Single and multistage centrifugal pumps (Francis or Axial) impellers and guide vanes. Impeller with a taper or key and pump shaft coupling. Submersible motor is a structural form, mainly by the chassis, stator, rotor, up and down the bearing seat and other components, the structure of the bearing, the use of rolling bearings, lubricated with water-resistant grease, and a sealed oil seal. The same type of structure of the motor are water-filled submersible motors, stator windings with insulating sheath water-resistant wire, rotor coated with a water-resistant anti-corrosion coating, motor shaft extension oil seal and sand thruster to prevent the sand into the body . When the submersible pump connected to 380V three-phase AC, the stator windings produce a rotating magnetic field, so that the motor rotor rotation, impeller rotation, so that the impeller on the water for work, the impeller water through the guide vane body and the outlet pipe to the required the height of.
Multi-function Artificial Grass
Multifunctional artificial grass is a synthetic turf material, usually made of polypropylene, polyethylene, polyurethane and other materials. It has the following characteristics:
1. Strong durability: Multi-functional artificial grass is specially treated to withstand high intensity use and various weather conditions, and is not easy to wear and fade.
2. Good environmental protection: compared with natural grass, multi-functional artificial grass does not need to use pesticides and fertilizers, and will not cause pollution to soil and water.
3. Easy maintenance: Multi-functional artificial grass does not need watering, pruning and fertilizing, and only needs regular cleaning to keep it beautiful.
4. Strong versatility: multi-functional artificial grass can be used in a variety of occasions, such as indoor and outdoor decoration, sports venues, public places, etc.
5. High safety: Multifunctional artificial grass surface is smooth, not easy to slip, more safe for athletes and children.
In short, multi-functional artificial grass is an excellent lawn material, with durable, environmental protection, simple maintenance, multi-functional and other advantages, suitable for various occasions.
