Pump flow. Users according to the courtyard planting, breeding, processing and living water demand, water conditions to consider the use of conditions. If sufficient water, according to the maximum water demand to determine the pump flow. Make sure that the flow of the selected pump is basically in accordance with water demand and water conditions.
Pump head. Pump head should be greater than the actual water level. Under normal circumstances, the head of the selected pump wxb series should be 20% larger than the actual lift; wq series should be 10% larger than the actual lift. Otherwise, the pump is difficult to pump water. Power supply. The motor voltage for the three-phase power supply is 380 volts; the motor voltage for the single-phase power supply is 220 volts. General household lighting power supply is 220 volts, therefore, the purchase of 220 volt power supply micro-pump more economical and convenient.
Installation size matching. Such as the use of micro-submersible pump wq series, we should pay attention to the maximum diameter of the pump should be less than the hole diameter, otherwise it can not be installed into the well. Such as the selection of wxb series of micro-pump, should be considered good and well assembly form (direct counterpart pumping, the original pipeline supporting pumping, hand pump with pump, etc.) the feasibility of the program.
A carbon steel plate has usually been considered as the steel that does not contain much alloy steel elements, also named as mild steel. Generally, elements are C, Mn, P, S, Si, besides these, there are no minimum limits for elements of Al, Cr, Ni, Mo, V, etc.
Carbon steel plates are available in different grades depending on the carbon content and strength.
As the content of Carbon increase, the steel plate hardness increases.
Low carbon steel plate: For carbon content 0.06% to 0.25%, also we call it mild steel plate.
Medium carbon steel plate: C content from 0.25% to 0.55%.
High carbon steel plate: 0.55% to 1.0%, also called hard steel plate.
Low carbon steel is the most common form, and it's very malleable and ductile. Medium carbon steel balances ductility as well as strength for excellent wear resistance. High carbon steel is exceptionally strong, while ultra-high carbon steel can be tempered to even greater hardness but no malleability.
As the percentage of carbon gets larger, steel can become harder and stronger through heat-treating. Carbon steel is usually heated to change the mechanical properties of steel, usually ductility, hardness, strength, and resistance of impact. Increasing the carbon content of carbon steel makes it harder and stronger, but reduces the steel`s ability to be welded, making it more brittle.
Carbon steel plate is most often used for structural purposes such as buildings, yet it has the flexibility to be worked into ornate designs. Low carbon steel sheet (wrought iron) is typically used for fences, chain links, gates, and railings. Structural steel (medium carbon steel) is used in cars, refrigerators, washing machines, buildings, and bridges. The steel sheets are normally made up of medium carbon steel.
