Mine submersible pump performance parameters

Mine submersible pump main performance parameters of rotating speed; Flow; Allow the vacuum suction height; Shaft power; Gas turbid allowance; Efficiency; Lift. Traffic is also called water output, mine submersible pump in a period of time the number of water transfer, the general unit of time for the m3 / h or L/s. Head for the total head in mine submersible pump is sending to the height of the liquid, in the international engineering with pressure Pa said. Head is said mine submersible pump pumping water than can increment parameters, can flow into the water than E1 - Can discharge water than E2 = mine submersible pump head, so the water pump lift and appreciation than can. We need to calculation of line loss in the practical engineering. Shaft power is conveyed in the role of the motor to drive the impeller pump shaft power, expressed in N, unit expressed in kW. Mine pump efficiency is equal to the ratio of power/pump shaft power effectively. Motor to transfer electric pumps, impossible to transmit all water supply, in the interior of the water pump will have certain loss. We have in the engineering of shaft power and pump efficiency, we can calculate the power consumption, this is also the main part of the project cost accounting. Mine is known as the speed of the pump impeller velocity, expressed in motion is the number of units in a minute. The unit is r/min. The use of mine water pump in the standard case ( Normal atmospheric pressure) , suction on the vacuum pump run-time height, directly influence the water absorption performance. Air turbidity allowance is the energy of the steam pressure at the entrance of the pump, more than a certain amount of liquid saturation pressure impact. Also impact absorption ability in different angles. More than six parameters of the general company is expressed as a performance curve, also is the important technical parameters of mine submersible pump. Of course are all clearly marked on the product nameplate.
J&T INDUSTRY CO.,LTD. as one who also teaches operations about how we use our whole operating system as a way to gain advantage and create considerable value and capture value in a sector where, in essence, the environment is quite hostile from a competitive point of view.
Exceed customers' expectations in the procedures of manufacturing submersible pump.
There are so many factors that businesses have to weigh when producing submersible pump, and we are not going to pretend to grasp all of them.
