Q:Water pump dead center lift
Pump downstream equipment design pressure is greater than 3MPa, if it is 400 meters, the downstream equipment design pressure is greater than 4MPa
Q:Operating procedures for measuring pumps
Pressurization(1) for the discharge pressure below 2.0MPa, then the pump stroke length should gradually increase, each increase of 20%, to maintain 15 minutes.(2) for the discharge pressure greater than 2.0MPa, you need a special pressure, to ensure that the pump discharge pressure gradually increased, each time for the final row pressure of 20%.(3) when the pressure is not increased, the stroke of the pump is gradually increased by 20% strokes per time.Note (1) when pressure is applied, the pressure gauge should be observed at the side of the loading side (slow motion)(2) check ammeter, forbid overload
Q:What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system?
Large pump control valve controlled energy consumption at least 30% reason is that there are serious throttling loss of a throttle valve control system of severe fever but simple structure and low cost which is why now valve control system still occupy the main market reasons.Pump control system with complicated structure especially when serious nonlinear control unsymmetrical cylinder control effect is not ideal, but the biggest advantage is energy-saving and low fever America professor Monika points out that using the pump control system of hydraulic excavator energy efficiency compared with the valve control system can be improved by over 46% but costs are high. But in control, the three pump invented by Professor Quan LONG of China is a good solution. LZ can find the invention patent or find his paper on sage. It seems that there are three or four SCI about this pump
Q:Why does the centrifugal pump start and close first when the outlet valve is closed?
When the valve is closed off opposite is the first current to the rated current, avoid instant electricity loss of other electrical equipment caused by voltage fluctuation. At the same time, some centrifugal pump outlet check valve is not installed, the role of avoiding the pipeline caused by backflow of water pump reversal.This Regulation (or operation regulation) is generally applicable to larger power centrifugal pumps. For small power equipment, it can be used to determine whether the above operation is necessary for actual use
Q:What are the important parameters of 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 acceleration of gravity, is the effective energy output from the pump in unit time of liquid -- effective power pump:Pe= P gQH (W) = QH (W)In the p - density of liquid pumping (kg/m3);Gamma - pump heavy liquid delivery (N/m3);Q - pump flow (m3/s);H - pump lift (m);G - gravitational acceleration (m/s2)The shaft power P 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.
Q:How many square cables does the submersible pump for 7.5KW need?
According to current I=13A, it is estimated that the cable is less than 10 square meters, so the cable cross section can be calculated at the ampacity of 5A per square meter. The square section of the cable is =13/5=2.6 square. According to the specifications series, optional 2.5 square aluminum cables. When the cable is longer, it is safer to choose 4 square aluminum cables.
Q:What's the submersible pump?What is a submersible pump, and what about it?
Submersible pump is a pump directly on the water inside the pump, eliminating the water inlet pipe, eliminating the trouble of ordinary water, is very convenient, just a pool, pool, bucket, water tank water level is shallow to be able to work, meet your requirements of pumping drainage
Q:What is the lift of diaphragm pump?
Diaphragm pump lift is different from the centrifugal pump, refers to the diaphragm pump can raise the height of water, the unit is meters water column. Lift depends on the size of the outlet pressure, the pressure per kilogram is equivalent to 10 meters height
Q:How can the submersible pump level meter be connected?
Installation of submersible pumps dedicated liquid level float, connected to the submersible pump power line (some submersible pumps bought with), or received submersible pump control circuit, high starting, low stop.
Q:What is the difference between the ground pump and the pump in the commercial concrete?
What you should say here is the concrete pump.Ground pump: the pump will be placed in a position on the site, the pipeline will be sent to the construction of concrete surface,
