Application and Installation
They are recommended for draining dirty water and sewage in the domestic and civil sectors. Being equipped with a single-channel impeller, they are allowed to pump liquids containing suspended solid bodies with dimensions up to 35 mm and short fibres. They are ideal for pumping drainage water, sewage or waste water for a single dwelling, and for clearing surface or nuisance water. These pumps are outstanding in their reliability in fixed installations with automatic operation.

Q:Is the centrifugal pump large or small?: Centrifugal pump, the smaller the better the cavitation.1, centrifugal pump cavitation less, anti cavitation performance is better, the pump cavitation is called the necessary cavitation margin or pump inlet dynamic pressure drop, the smaller the better. Generally speaking, the pump cavitation is the need for cavitation, the pump inlet pipe said effective cavitation margin, that is, the device cavitation margin. For a given pump, at a given speed and flow rate required NPSH is called pump necessary NPSH, also called NPSH, is required to achieve the performance parameters of the pump cavitation, the internal flow and the centrifugal pump is composed of pump head itself, its physical meaning is that liquid drop in pump inlet pressure part degree, is to guarantee the pump cavitation does not occur, with surplus energy exceeds the vaporization pressure head at the inlet of the pump unit weight of liquid. The cavitation must be independent of the device parameters. It is only related to the parameters of the inlet of the pump. These parameters are determined by the geometric parameters at a given speed and flow.

Q:Advantages and disadvantages of centrifugal pumps?: The centrifugal pump has no valve, so it is suitable for conveying suspended liquid, and the special design can also transport large solid suspensionThe pump can be made of chemical resistant material, which is suitable for conveying corrosive solution.The utility model has the advantages of simple structure, few parts, little failures, durability, low maintenance cost, convenient management and reliable work.The output can be adjusted even by the discharge valve fully closed, there is no danger of infinite rising pressure head.The liquid is transferred to a large quantity. And the pressure head does not require large, most suitable for centrifugal pump.

Q:I want to know the concrete under 60 type pump performance, it is mainly the pump long spiral bored piles, such as the diameter of the pump, transportation distance, pumping height and so on, thank you!: Maximum theoretical vertical transfer distance is m 270Maximum theoretical level conveying distance m 1200Distributing valve form S pipe valve (whole casting)

Q:What is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?: The unified corrosion resistant design of bronze impeller improves the corrosion resistance of the pump, and the stainless steel material is more suitable for more severe applications;

Q:What do you mean by the self coupling device on the pump?: Installation of GAK self coupling device:The installation of automatic coupling submersible sewage pump is mainly the installation of coupling device and the lifting of pump. In the pump before the installation of the rings on the chain, and the pump used for lifting.Installation procedure of coupling device:The coupling frame with four bolts fixed on the pump body; the water outlet pipe is fixed on the substrate; positioning cone mounted on the pipe seat; the lower end of the guide pipe is sleeved in the positioning cone, the upper end is sheathed on the guide rod of the rubber block; the guide rod frame is fixed on the pool wall. The function of the rubber block: the axial compression degree of the rubber block is adjusted by the screw on the guide rod frame, so that the diameter of the rubber block is consistent with the inner diameter of the guide rod, and the guide rod is stable.

Q:Why does the centrifugal pump close the pressure to start?: The motor power is selected according to the rated flow of shaft power points plus 15 to 25%, if the outlet valve is fully open to start, the pump flow may deviate from the amount of fixed lot, pump efficiency also reduces a lot, resulting in shaft power greater than the motor power caused by tripping even burned electric machine.

Q:How to calculate the motor power of metering pump?: The total mechanical power and hydraulic power, divided by the overall efficiency of pump, and the pump head and the utilization rate of pump mechanical efficiency, and then multiplied by 1.1 times (API675), you can get a metering pump motor need more power.

Q:How to install, operate and maintain the pipeline booster pump?: When the pump leaks, check it immediately to prevent leakage. If it leaks with the motor connection, replace the mechanical seal. Check that the power is connected. Is the supply voltage consistent with the operating voltage of the pump?. If the above a and B are normal, please remove the pump, open the pump cover, remove the foreign body in the pump, and then pump the lid on, and then tighten it to normal.No water pump, pump installed in the tap water pipeline, such as tap water level in the pump impeller on the plane (horizontal installation) or center line (vertical) below, you should turn off the power supply, to tap water level rise more than the impeller plane or the center line, connected to the power supply, to avoid mechanical damage (automatic no need to turn off the electric type). When the pump used in pumping wells, please check whether the water inlet pipe leak; pump cavity storage is not enough, should be filled with water, whether the suction process is too high, proper adjustment. Check whether the inlet and outlet diameter is too small or blocked. Automatic type after a period of time, there may be automatic failure phenomenon, mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging, can be re used.

Q:How to maintain and repair the booster pump of pipeline pump?: I. installationAssembly and disassembly1. scrub all the spare parts to be cleaned.2. mechanical seals are installed on the main shaft of the motor, and a small amount of clean turbine oil or 20 oil is added to the surface of the mechanical seal.

Q:How many kinds of pumps are available and the operating principles of various pumps?: There are many kinds of pumps. There are different classifications according to different standards. If classified according to the principle of work, can be broadly divided into the following four categories:1, vane pumps: centrifugal pumps, axial pumps, mixed flow pumps, vortex pumps, etc.;2, displacement pumps: piston pumps, piston pumps, diaphragm pumps and so on;3, power rotary pump: screw pump, gear pump, etc.;4 、 special function: jet pump, water hammer pump, magnetic drive pump, etc.;
