Product Description:

Production Introduction:
WQ blockage-free sewage submersible pump(hereinafter as pump) is untegrative motor and pump. Which is manufactured based on absorbing domestic and foreignadvanced technology and advantages. Impeller, designed with hydraulic model and made by precision casting, has the advantages of energy-saving, anti-winding and non-clogging,etc. At the same time, the pumps have a unique effect in the carriage of solid particles and long fibers garbage. Single or dual impeller structure ensures the pump has the higher efficiency when it has bigger flow. So this king of pump is a ideal drainage pumps for industries and cities.

Q:How many concrete pump tube diameter
The pump tubing diameter is 125MM general concrete or mortar pump tube diameter is 80MM fine stone
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:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
The power of axial flow pump decreases with the increase of flow rate, and it is a steep curve, so the centrifugal pump starts with an open valve.
Q:Why is the flow of the pump too small will occur cavitation phenomenon?
Throttling regulation is to change the opening of the valve to change the flow of the pump, that is to say, to change the characteristic curve of the pipeline. The commonly used to regulate the flow of exports, because the entrance throttle makes reduce the inlet pressure caused by cavitation danger.
Q:What's the word "pump"? Is that what advocates mean?RT
Is generally believed that the "wholesale" is the "hoarding" of "hoarding" variant, can be used to replace the word "store". And "wholesale" compared to "store" is clearly better and better recognize, because the "store" is a phonogram, hoard shaped characters "mouth", said the biggest the range of aggregation, like a grain bin; "Tun" is also phonetic, semantic. Tun, originally refers to the grass speared out of shape, with curly tails, and gathered the meaning.In this case, the "fans" can be written as "Yong Tun". But this is also troublesome, because the "store" in addition to read "Tun" (Ping Sheng), another pronunciation of "Dun" (Qu Sheng), who said food utensils, when we had the "Valley" store. So, if the "fans" to "hold", is also wrong. "Bin Zhao Wei fans" although it sounds strange, but at least not ambiguous; if changed to "Zhao Wei", is that we have to hoard may hear "Zhao Wei" or "Zhao Wei hold hip", hold the shield this is not the more the more chaotic change it!It is suggested that the "fans" to "fantastic", the modified method was acceptable. In modern Chinese, "public" does not necessarily mean that many, can also refer to a single. "One of the masses", "one of the audience (or audience)" this kind of argument, has been about good. Since this kind, we say "a fantastic" what not? "Fantastic" at least than the "fans" straightaway. The problem is, the word and Hong Kong Standards, there is no "fantastic".
Q:What's the meaning of the pump head in the water pump, please advise, thank you
The pump head of the centrifugal pump refers to the shell that contains the impeller and impeller, and also includes the shaft part that drives the impeller. It can be used as the part of the motor and shaft coupling and the base.
Q:How is the pump level of submersible sewage pump determined?
Pump water level must be higher than the water pump top, so that the motor running in the lower water temperature cooling environment, otherwise long-term operation will burn the machine
Q:Why can the centrifugal pump hold down the pressure?
The centrifugal pump can hold pressure because of the suction pipe in the pump at the entrance of a non-return valve (valve).
Q:What does "anti pump" mean in pump operation?
Function: anti pump effect when used for pumping concrete pumping occurs overpressure, the pumping pressure is above 25MPA, the concrete conveying pipe out of ash, can be understood as the precursor of pipe blockage, at this time should immediately use the anti pump, the concrete from the conveying pipe in the suction into the hopper, thus preventing plugging happen
Q:How high can the pneumatic diaphragm pump be?
If the pump material made of polypropylene (PP) material, corrosion resistance, good chemical resistance using PP material produced by pneumatic diaphragm pump can resist medium low cost, good generality, polypropylene material mainly is especially suitable for general acid-base liquid, using poly propylene made of plastic gas diaphragm pump can only withstand the highest temperature to 65 degrees, more than this number of polypropylene plastic deformation.
