The pump is a machine that transports liquid or makes liquid supercharged.It transmits the mechanical energy of the original motivation or other external energy to the liquid to increase liquid energy. It is mainly used to transport liquids including water, oil, pH, emulsifier, suspension, and liquid metal.And liquid containing suspended solid objects.

Pump up
The water pump is the highest height that the water pump can send the water. Generally, the symbol "h" is expressed by the unit. For example, if the pump is marked with 1.1 meters, that is, this is this one, that is, this is this.The height of the water pump can be delivered to 1.1 meters.The water -absorbing process and the pressure of water pump together constitute the pump.Among them, the water absorption journey referred to as "suction", which refers to the vertical height from the center line of the water in the water source to the water surface of the water.
Pump repair
The water pump maintenance method is caused by the user when the user encounters the heat pump during use. This is usually caused by the bearing damage, the bend of the pump shaft or the two axis different hearts, the tightness of the tape, and the failure of the leaf wheel.At this time, the user must investigate the specific reasons one by one. It can use methods such as replacing new bearing, adjusting the pump shaft or two -axis, adjusting the tightness of the tape, and adjusting the impeller.Water pump maintenance method can not be suck water. It can be said to be the most common failure of water pumps. This is usually caused by air or gas accumulation in the pump in the pump.Causes that it cannot suck water.At this time, the user can press the water, and then fill the pump body with water, and start checking whether there is air leakage in the inverse valve, pipelines, joints, etc.If there is a leakage, you can apply lubricating oil and tighten the screws at the joint after disassembly; if the joints leak at the joint, you need to tighten the nut. If the leakage is serious, you need to re -disassemble. At this timeNote that the tube with cracks should be replaced.
Pump price
There are many models with water pumps. Generally, the price of 125W for living water is automatically at 180-200 yuan. The submersible pump between 230-260 is slightly more expensive but not as good as this.
Pump model
To say the most energy -saving pump, then choose the E pump. The so -called E pump is a pump with a frequency frequency motor, that is, an integrated inverter is integrated on the motor of the pump, which can be run in the opening or closed mode. ThisThe pump should be the most energy -saving.At present, the commonly used water pump series such as CR, CM, NBG, NKB, TP, etc., all of which provide suffering from the inverter pump pump of suffix E series.
