Q:Why can't the inlet of centrifugal pump be negative pressure?
Therefore, the centrifugal pump inlet pressure can be negative, and negative number, should be used to pump cavitation margin and liquid saturated steam pressure parameters to specific calculation. Sometimes, the liquid saturated steam conveying pressure is very high, such as the 9 m water column, then the minimum pressure of the pump inlet should be equal to 4+9=13 meters, the atmospheric pressure is higher than 3 meters, not only for negative pressure, even higher than the atmospheric pressure to work properly.
Q:Filter backwash pump for what use, what is the principle of work ah?
When the filter is in normal operation, the impurity will be trapped in the upstream of the filter (filter medium). As the accumulation of impurities, the filter media will be blocked, and the direct performance is that the circulation will decrease. Usually, when the flow drops to a set point (the industry is usually judged by the pressure drop),
Q:Why do we need to stop the pump?
And the pump at the start, if the valve opening pump, then the pump outlet pressure (head) is very small, so the pump flow will be great, the pump power is very large, causing the start-up current is very large. In addition, the starting current of the motor itself is also very large. These two factors add up to the possibility of overloading the motor, resulting in failure to start or even burn the motor.
Q:What is the series of pumps? What's the difference between a unipolar and a multistage?
Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)
Q:What is the minimum continuous flow of a pump?
Quality solutionsMinimum flow of pump, minimum continuous flow of pumpIn order to ensure the proper use of the pump and the normal operation of the pump manufacturer will indicate the minimum pump in the sample of the continuous operation flow, the correct selection or use to warn or instruct users. According to the provisions of the API standard, the minimum continuous flow into the minimum continuous stable flow and continuous flow. Most small thermal limit(1) the minimum continuous stable flow.API standard specifies the minimum continuous stable flow refers to the vibration limit does not exceed the standard set by the pump can work normally. The minimum flow pump at small flow rate, there will be noise and vibration increase, API of this provision is to ensure that the service life of the pump, avoid due to improper operation of the pump caused by the adverse effects.
Q:Variable flow pumps are variable pumps
Yes. The variable pump is designed to change the flow rate
Q:What is the pump, how to classify, mainly used in where?
2. other classification of pumpsThe pump can be divided into two parts according to the position of the pump shaft:1) vertical pump2) horizontal pumpDivided by the number of suction ports:1) single suction pump (single suction pump);2) double suction pump (double, suction, pump)According to the prime mover of the drive pump:1) electric pumps2) steam turbine pump3) diesel engine pump[other details]
Q:Does the reservoir water heater press the booster pump (high marks)?
The outlet water pressure of hot water is the same as that of cold water. The water heater is pushed by cold water to push out the hot water. (of heating). Installation location about 2 meters away from the ground, the impact of water pressure is not large, in rural areas, the installation position in more than two buildings will have an impact. In the city, the installation position is above four floor to affect the water pressure.
Q:What are the differences between the sewage pump and the clean water pump?
2. in order to prevent the wound, water pump impeller design is more simple but not ring pump, equipped with tips, cloth and other debris can be crushed after the pump, and the impeller water pump is relatively complex, but the efficiency will be significantly higher than the former.Why can't the sewage water pump and impeller: because features of key design, resulting in water pump for sewage situation is likely to occur, blocking, winding, wear and corrosion occurs, resulting in damage to pump or scrapped, so water pump can not be used for sewage.
Q:What are the basic technical parameters of the pump?
The effective power of pump and output power, with Pe said. It is the effective energy per unit time from the pump in conveying out liquid obtained in the pump. Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and the acceleration of gravity. Is to obtain the output from the pump in unit time of liquid effective energy - efficient pump power: Pe= P gQH (W) = QH (W) - P - density of liquid pumping (kg/m3); severe gamma - pump for transporting liquid (N/m3) - Q (pump flow; m3/s; H) - pump head (m); G (m/s2). The acceleration of gravity P axle power and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said. Selection of related pumps:
