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:Who can tell me such water pump medium flow direction should be what kind of, from left to right, or from right to left, is low into the higher?
Low inlet and outlet
Q:The role of impeller in water pump
The impeller rotates at high speed so that the centrifugal force is generated by the water, and the vacuum is generated in the middle of the impeller, and the water source is continuously sucked into the impeller to increase the kinetic energy of water and play a role in promoting water.
Q:50 meters deep well with what water pump: home?
For deepwater submersible pumps, ordinary submersible pumps are inefficient.
Q:Pump adapter belongs to the system of fire pool equipment?
Not belong to. According to the specification, fire hydrant system and automatic sprinkler system fire water supply pipe should be installed on the pump adapter, therefore, it belongs to the fire water supply facilities.
Q:Fire hydrant and fire pump adapter difference
Fire hydrant is out of water, the water pump is water supply to the pipe network
Q:What does water flow mean?
The amount of water delivered by the pump during the unit time, that is, the flow of the pump. Generally, there are three kinds of time units, namely, seconds, minutes and hours. In our country, the unit of flow adopts the international metric units, liters, milliliters, cubic, thousand cubic meters, etc., and different units are used according to different usage environments.
Q:What are the conditions for the series and parallel connection of the pumps?
Parallel pumps: the pump is required to lift the same. This effect is to increase traffic.Pumps in series: requirements are similar to the flow of water pumps. This allows you to increase the total head and recommend adding small pressure tanks during the series connection.
Q:Is it illegal to produce aluminium submersible pumps?
When buying, if you ask for a copper wire or a wire, and don't answer you, it's against the principle of good faith. On the contrary, if you did not ask to buy the water pump with aluminum core, then there is no violation. Because the country does not have any laws and regulations prohibiting the production of aluminum core wire motor, naturally there is no aluminum wire motor as a fake and shoddy products, there is no pre notice obligations.In fact, the aluminum core motor is good, and the price is low, especially in the dry environment of small and medium-sized motors, with good performance. Only used in submersible pumps, because aluminum is easier to damp than copper wire, due to bacteria and other corrosion, and its life is sometimes less than copper wire. But the water pump, aluminum often needs to rewind coil, because of a small submersible pump motor is not good around general scrap.
Q:How should the water pump breaker be selected?
If it is a single-phase motor, rated current is 75A; three is about 30A; the contactor should be 1.1-1.5 times the rated current of the motor protection type selection of circuit breaker, circuit breaker: RMM1-100/33002 or 50A motor comprehensive protector, the price is not expensive.The circuit breaker (English Name: circuit-breaker circuit, breaker) refers to the closing, carrying and breaking current conditions and normal circuit switch device, load and breaking current loop abnormal conditions within the stipulated time. The circuit breaker is divided into high voltage circuit breaker and low voltage circuit breaker according to its range of use. The demarcation line of high and low voltage is fuzzy. Generally, more than 3kV is called high-voltage equipment.The circuit breaker can be used to distribute electricity, not frequently start asynchronous motors, the protection of the power line and a motor, can automatically cut off the circuit when they occur serious overload or short circuit and under voltage fault combination, its function is equivalent to the fuse switch and less thermal relay etc.. Moreover, after breaking the fault current, there is no need to change the components. At present, it has been widely used.Distribution is an extremely important link in the generation, transportation and use of electricity. Distribution systems include transformers and various high and low voltage electrical equipment. Low-voltage circuit breakers are a wide range of electrical equipment.
