Q:Excuse me, what is the water pump from the lotus root?

The pump is automatically coupled by the self coupling device to move downwards along the guide rod to the position, thereby achieving the simple and convenient effect. There's no need to jump into the septic tank when it's time to repair.When you buy a sewage pump, a professional person will ask you what kind of installation you need!

Q:What are the main performance parameters of the pump?

The amount of liquid supplied by a pump in unit time. Volume flow Q, unit m3 / s. There is mass flow G, unit is kg / s.

Q:How many pumps does the 80cm tank use?

Mainly look at the flow of the pump, all pumps have flow signs, such as 15L/HThe above is I at random, meaning that 15 litres per hour. You should calculate the volume of your cylinder, that is, the length of the tank, the width and the height of the water surface, the unit is cm. The result is 1000, which is the volume of your fish tank

Q:What's the meaning of the pump head in the water pump, please advise, thank you

According to China Wikipedia network, the basic components of the water pump: motor, coupling, pump head (body) and chassis (horizontal).Pump is generally composed of pump body and pump head, in which the pump body refers to the spiral case, impeller, bearing, oil shell and sealing assembly, etc., the pump head refers to the impeller, bearings, oil ring and sealing rotating parts (including shaft), etc..

Q:What are the failures and causes of the replacement of the fuel pump assembly?

Gasoline pump is the gasoline from the gasoline tank suction and the gasoline tank has a certain pressure, thereby, it overcome the resistance of the pipeline, pipeline and fuel filter into the carburetor float chamber or electronically controlled injection engine in the guide frame.

Q:What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.

The working principle of submersible pumpBefore the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.

Q:How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?

Water ring vacuum pump is divided into many types, different sizes, different types, so water is different. As for how much water the no fixed amount, but to ensure that the water temperature is in 25 degrees, not more than 35 degrees can be.

Q:How to select metering pump head?

The main index affecting the selection of the pump head is the composition of the medium to be transported and added, as well as the pressure and the temperature of the external environment

Q:Water pump does not produce water, what are the reasons?

The reason why centrifugal pump does not produce water:1. pump inlet or sink, water tank water shortage.2. water pump pipe blocked or valve not open.

Q:What is the difference between centrifugal pump and positive displacement pump?

The centrifugal pump is usually driven by an impeller, and the head has a functional relationship with the flow rate. Positive displacement pump is gear or piston drive, each stroke output flow is constant, and the head does not matter, the pressure head can be infinite.
