The basic performance of the pump, usually from six personalized parameters can be. 1. Flow (pump) Do not be in the unit volume of liquid pump carrier. In Q, the flow or unit is commonly used cubic meters / hour / s flow unit weight commonly used tons / hour 2. Supervisor (total responsible person) the power of the pump unit weight (1 kg) of liquid, which is Unit weight of liquid through the pump, centrifugal pump its energy value. As the letter H indicates, in units of kg · M & A / kg, it is also possible to pump liquid fluid up to the height (in meters) of the transfer column, which uses international pressure, Pascal. 3. Shaft Power The water pump shaft is derived from the original motive power delivered to the N-axis power said. For the electric drive prime mover, shaft power unit kW said. 4. Efficiency Pump effective power and shaft power ratio η said. The efficiency of the pump is as follows: η = N u / N η = N U / N where N - shaft power in kilowatts; U - effective force, that is, the unit, every time the liquid flows through the pump to receive pump energy, kW. The effective power of the pump is: Nu = γQH / 102 Nu = γQH / 102 5. Speed ​​The speed of the impeller of the water pump is usually the transit time per minute, the letter said, N said. r Normal unit / minute. (The speed of the reciprocating pump is usually expressed as a reciprocating piston (number of sub / min.) 6. To allow for height and cavitation vacuum suction to allow suction at a high degree of vacuum The pump standard refers to a country (ie ATM temperature 20 ℃, 1 surface pressure), running, the maximum allowable height of the vacuum pump suction. With the HS said that the single-bit MH2 pump factory serum Hs commonly used to reflect the centrifugal pump SAP. Pump cavitation refers to the liquid inlet Unit weight has exceeded the saturated vapor pressure of rich energy sources. HSV said unit mH of two Australia pump cavitation device commonly used to reflect the axial flow pump, boiler feed pump, such as SAP. Pump cavitation samples also said that only in the HS The value of herpes simplex virus, they are from a different perspective reflects the water pump performance is good or bad parameters, the greater value of the HS, the pump water absorption is good; the greater value of herpes simplex virus, water pump Worse performance.
A Shower Faucet (also spigot or tap: see usage variations) is a valve controlling the release of a liquid that enabling washing and drying in the bathroom.
