- Q: What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
- When the pump is working, the liquid at the inlet of the impeller, due to a certain vacuum pressure will produce steam, the vaporization of the bubble in liquid particles under the impact of movement, the impeller and other metal surface erosion, thereby damaging the impeller and other metal
- Q: I would like to ask, constant pressure pump set pressure 20Mpa, the actual load is 15Mpa, then the constant pressure pump outlet pressure? If it is 20Mpa, then where is the loss of 5Mpa? If 15Mpa, the constant pressure pump 20Mpa how to understand? In addition, the constant pressure pump pressure is defined when the flow began to reduce the point, or a sharp drop in flow after the point?
- 15MPa. 20MPa means that if you enter the 20MPa, the variable mechanism will work, and the flow at this time automatically matches the load. 20MPa used to supply the fuel by maximum displacement.
- Q: What's the difference between non negative pressure and variable frequency water pump?
- No negative pressure is superposed pressure intelligent frequency conversion equipment, pump frequency operation is no negative pressure difference, and the variable frequency pump, variable frequency pump is advanced municipal tap water tank or pool, pump from the tank or pond water pressure to set pressure to the pressure water supply, and no negative pressure directly from water the municipal pipeline, using the original municipal 2~3 kilograms of pressure
- Q: Difference between pump and compressor
- Working principle：The impeller is installed in the pump casing and is fastened on the pump shaft 3, and the pump shaft is directly driven by the motor. There is a liquid suction in the center of the pump shell, and 4 is connected with the suction pipe 5. The liquid through the bottom valve 6 and the suction tube into the pump.The liquid discharge port 8 on the pump housing is connected with the discharge pipe 9. Before the pump starts, the pump shell is filled with the liquid to be transported; after starting, the impeller is driven by the shaft to rotate at high speed, and the liquid between the blades must also rotate. Under the influence of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and obtains energy, and leaves the outer edge of the impeller at high speed to enter the volute pump shell.
- Q: What is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?
- The 2BV vacuum pump belongs to the machine pump coaxial type direct connection design. It saves space and is easy to install;The use of mechanical seals as standard configuration eliminates leakage and easy maintenance;Smooth running, low noise to 62 decibels;
- Q: The working principle of magnetic pump
- Control of cooling fluid flowThe pump is running, you must use a small amount of liquid in the magnetic separation between the rotor and the casing annulus area and sliding friction bearings for flushing cooling. The cooling liquid flow pump design flow is usually 2%-3%, the annular area between the magnetic rotor and sleeve of eddy current generated because of high heat. When the cooling and lubrication the liquid is not enough or poor flushing holes to plug, will result in permanent magnet medium temperature is higher than the operating temperature of the inner magnetic rotor gradually loses magnetism, the magnetic actuator failure. When the medium is water or water-based liquid, can make the annulus area temperature maintained at 3-5 DEG C; when the medium or hydrocarbon oil that can make the annulus area temperature maintained at 5-8 degrees.
- Q: Common failure treatment of piston pump
- Table 15 common troubles and treatment of hydraulic pumpsFault phenomenon, x09 cause analysis, x09 elimination method(1) the pump does not carry oil; the x091. pump does not turn x09 (1); the motor shaft does not rotate1) missed connection power supply2) electrical wiring and component failure, x09 check electrical and troubleshootx09x09 (2) motor heating trip
- Q: What is the difference between the ground pump and the pump in the commercial concrete?
- Move back and forth; pour concrete into a certain area. After the filling is finished, the whole pump truck can be moved to another position quickly
- Q: Why can't the centrifugal pump pump the vacuum?
- Running process: depending on the centrifugal pressure of the liquid in the impeller, the liquid is sucked into the liquid, and the liquid in the pump shell has the conversion of the energy form, so that the fluid can obtain the mechanical energy mainly with the static pressure.The characteristics of the system: the suction diameter than out of large diameter, the general valve installed.
- Q: What's the difference between a concrete pump and a concrete pump truck?
- Concrete pump is a pumping machine used in the field, while the concrete pump truck is a truck mounted pump.
