Q:How do you do the yellow water from the suction pump?.
If your pump is iron, it must be impossible to avoid rust, and if you replace it with stainless steel, there will be no problem.There is also a way to add a filter or water purifier at the front of the pump to make it a little better.You can change the flow parts into stainless steel, but the price may not be cheap
Q:The reason why the pump is overloaded
Main reasons: 1. bearing lubrication is not good or bearing quality problems appear peeling phenomenon, resulting in increased resistance to pump operation.2., the pump cover and impeller clearance is too small, the impeller mouth and pump cover friction.3 belt tight, resulting in heavier load.4. centrifugal pump power is proportional to the flow, the greater the flow, the greater the power needs, large, low head flow, resulting in heavy load.Water pump maintenance: 1., water pump to do routine maintenance, check the water seal every day, to prevent water damage, water directly into the bearings, accelerated wear and tear.2. belt adjustment should be appropriate, not too loose, too tight.3. strictly according to the standard operation, for the low lift pumping load, it is necessary to control the flow by throttling, thereby reducing the load.
Q:What is the water pump population pre rotation, what harm?
Is the entrance of water flow in the formation of complex turbulent flow, flow direction, shock, vibration, easy to damage the front entrance device, such as vane impeller, shaft sleeve, sealing element. In order to prevent the emergence of the pre swirl phenomenon, usually the design will inlet than outlet diameter, try to make the entrance flow in laminar flow, according to streamline our design, in order to protect the safety and prolong the service life of equipment.
Q:What does "ETA" mean in the selection of pumps?
Water pump selection table "ETA" is the meaning of efficiency. NPSH refers to the pump's cavitation margin.ETA is abbreviated as "efficient ratio", and Chinese means "water efficiency". The efficiency of the pump here is generally referred to as the efficiency of the pump design point because the actual efficiency of the pump varies with the pump operating conditions. The efficiency of the ETA can also be interpreted as the efficiency of the pump at the rated lift (or rated flow).
Q:About water pump selection
0.1MPa 1, according to the water pressure of the hydrant, dry season difference 17m geometric head for 17m, the pipeline resistance calculated according to 10%~20% 1.7~3.4m, from 3m, so the pump head should be 17+3+10=30m, considering that this is the dry season conditions, when the water level elevation is lower than 17m when the actual demand of low lift in 30m, it is not recommended to 35m head to head design, 30m under various conditions are enough (the actual operation of pump lift by lift device, so if the head is too high may lead to the actual use of pump bias conditions, and low lift and large flow operation, the flow of super power) selection of I don't know your personal needs, can not make a judgment, suggestion the flow rate and pipe diameter according to the economic flow rate of 2.5m/l is about to take it.2, from the operation of the pump, it is best to water intrusion, is higher than the pump center line, so it is best to get the pump installed under the negative on the second floor, if you can not meet the high water pump and the center line, there are three choices in the selection of a pump: 1, submersible pump (by landlord excluded); 2: the ordinary centrifugal pump + water diversion device (water diversion valve then available irrigation water or vacuum diversion device, this approach might not be used, and irrigation valve trouble, valve is broken with it, such a small pump vacuum water cost is too high); 3: self suction pump. Recommendations may consider self suction pump, self-priming pump is also divided into no sealed automatic control self-priming pump and general cantilever self-priming pump both, but the installation height is still lower, the better, because the lower the water level of the entrance, the more likely to suck water.
Q:1.5 kW three-phase pump with 600 meters line, should match what big line?
1.5 kilowatts water pump distance 100 meters, with 2.5 square meters of electricity enough
Q:Why can't vertical water pump use spring shock absorber?
Vertical pump can use spring shock absorber, because the bottom of the vertical pump installation area is small, so many people feel that it can not install spring shock absorber, actually not, and now there is a vertical pump can use the shock absorber;Introduction of spring shock absorber for vertical pump;1 、 spring cover and spring seat for the combination of butyl glue and cast iron, and after baking treatment, good weather resistance.2, according to simple installation, bolts can be used to adjust the height and level.3, can be matched with the pedestal design, can be used in various types of machinery and equipment.4, applicable to all types of pumps, fans, air conditioning boxes, pipes and so on.
Q:Is the pump lift horizontal or vertical?
The vertical height from the center line of the pump impeller to the surface of the water source
Q:The water burst how to repair?
If it is not too serious, with casting glue on the line, it is best to use serious brazing, don't use the electrode,
Q:How does a pump pump water?
Centrifugal pump is the use of centrifugal force to increase the pressure of water and make it flow of a pump. It is composed of pump shell, impeller, rotating shaft and so on. The motor drives the rotating shaft, the rotating shaft drives the impeller to rotate at a high speed in the pump casing, and the water in the pump is forced to rotate with the impeller to generate centrifugal force. The centrifugal force forces the liquid from the impeller periphery to throw, the high speed, the high pressure water flows through the pump shell outside the pump, the impeller center forms the low pressure, thus draws in the new water flow, forms the unceasing water current transportation function.
