- Q: Why does the centrifugal pump close the pressure to start?
- Therefore, the operation rules of multistage centrifugal pumps require that the inlet valve be opened before opening, and the outlet valve is closed. However, the export valve closed time can not be too long, because at this time the medium in the pump cycle, the medium temperature gradually increased, easy to cause mechanical seals, due to lack of lubrication friction and wear or damage.
- Q: You'd better point out the details.... There are 2 best ways of experience and formulaCan you say a simple point, such as multi-stage pump, when the pump is higher than the motor, 30 wire is the next mouth how to do?
- For the first time, the pump and motor were placed on the base and not fastened (Cu Zhaozheng);Second times, the pump and motor have been tightened, the inlet and outlet flange bolts are not fastened;Third times, the pump runs 24 hours later.
- Q: Why can't the inlet of centrifugal pump be negative pressure?
- Can be negative pressure ah, the negative pressure here refers to the pressure is less than the atmospheric pressure, but the pressure can not be too low, to prevent water vapor below the saturated vapor pressure, so that water vaporization, cavitation phenomenon, the centrifugal pump will be considered.
- 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's the meaning of the pump head in the water pump, please advise, thank you
- In general, the pump removes the motor, and all the fittings are part of the pump head.A pump is a machine that transports liquids or pumps liquids.
- Q: How high can the pneumatic diaphragm pump be?
- Pump made of polyvinylidene fluoride (PVDF) material two, the series of pneumatic diaphragm pump belongs to the fluorine plastic pneumatic diaphragm pump is also known as the corrosion products of pneumatic diaphragm pump, diaphragm liquid contact using PTFE material, using PVDF material produced by pneumatic diaphragm pump is mainly used in corrosive the pH, mainly used for chemical liquid conveying multiple solvent, corrosion resistance effect is very good. The series of fluorine plastic pneumatic diaphragm pump in high temperature less than 93.3 degrees.POM pump material also has good resistance to solvent and abrasion resistance, low friction resistance, moisture absorption is also low, the highest temperature of such pumps within 65.5 degreesPolytetrafluoroethylene (PTFE) membrane corrosion resistance is very good, in addition to liquid metal lithium, potassium fluoride, sodium fluoride, three chlorine, three fluoride high temperature oxygen, high flow rate, almost all of the chemical liquid transport (including concentrated nitric acid and aqua regia), PTFE material the maximum temperature to 176.6 degrees. However, for the diaphragm pump product as the diaphragm moves back and forth in work, we suggest that at a temperature of 120 degrees, the prerequisite is the pump body pump must be made of metal material and plastic material. The pump is the pump of PVDF material temperature is highest in less than 93.3 degrees.
- Q: Is the flow meter in front of the pump or after the pump?
- After the flowmeter is placed in the pump, it is better to add a pressure tank or a buffer tank, so that the flow meter will work better
- Q: The working principle of magnetic pump
- Structure characteristics1. permanent magnetPermanent magnet operating temperature range is made of rare earth permanent magnet wide (-45 - 400 DEG C), high coercivity, magnetic anisotropy direction is very good, also won't happen in the same demagnetization phenomenon when is close, is a good source of the magnetic field.2. isolation sleeveIn the metal isolation, isolation sets in a sinusoidal alternating magnetic field, in a cross section perpendicular to the direction of magnetic field lines induced eddy current and converted into heat. Eddy current expression is:. The Pe - K constant; eddy current; rated speed of N - T - pump; magnetic drive torque; F - the pressure inside the sleeve; D sleeve diameter; a material resistivity; and the tensile strength. When the pump design is completed, N, T is the given conditions, to reduce eddy current only from F, D, and so on. Non metallic materials with high resistivity and high strength production isolation, in reducing the eddy current effect is very obvious.
- Q: What's the difference between a centrifugal pump and a centrifugal pump? What are they used for?
- As the name suggests, centrifuges are machines that achieve centrifugal effects by centrifugal action. And you say the centrifugal pump is only specific, and the same as the pump
- Q: What is the difference between centrifugal pump and self suction pump? Which is better?
- If the centrifugal pump in full before the start of the shell of the gas, then start after the center of the impeller was thrown in the gas can not be large enough to form the vacuum, so that liquid in the bath can not be sucked, so the centrifugal pump to start before using foreign liquid in the pump housing space filling
