- Q:How high can the pneumatic diaphragm pump be?
- Diaphragm capacity, high temperature, pneumatic diaphragm pump ability, high temperatureMany users do not know how high the temperature resistant diaphragm pump, diaphragm pump either electric diaphragm pump or pneumatic diaphragm pump products it cannot do without diaphragm attachments, diaphragm materials mainly fluorine rubber, rubber, rubber, polyether road three EPDM, PTFE several, if not considering the gas temperature resistant diaphragm made of stainless steel. The temperature to 600 degrees of diaphragm pump diaphragm pump, but must use the diaphragm, so the diaphragm pump can Naiduo high temperature depends entirely on the diaphragm was affected by temperature, following to share various diaphragm pump diaphragm material and different material temperature choice diaphragm pump product right:
- Q:What are the main performance parameters of hydraulic pumps?
- Displacement and flowDisplacement refers to the pump (or motor) every turn a week, by the size of the sealing chamber geometry variable discharge (or enter) the volume of liquid, commonly used unit is ml/r (ml / rev). Displacement can be changed as a variable pump (or variable motor), and the displacement can not be changed into a quantitative pump (or a quantitative motor).Actual flow is the amount of flow at the outlet (or inlet) when the pump (or motor) is operating. As the pump itself leaks, the actual flow is less than the theoretical flow. As the motor itself has an internal leakage, to achieve the specified speed, in order to compensate the leakage, the actual flow of input must be greater than the theoretical flow.
- Q:What is the Rhodes pump?
- The ultimate vacuum of roots pump depends on the pump structure and manufacturing accuracy, and also depends on the limit vacuum of the front pump. In order to increase the limit vacuum of the pump, the roots pump can be used in series. The working principle of roots pump is similar to roots blower. As the rotor continues to rotate, the gas is pumped from the intake air to the space between the rotor and the pump housing V0, and then discharged through the exhaust port. Since the V0 space is fully enclosed after inhalation, the gas in the pump cavity does not compress and expand. But when the top of the rotor turns off the edge of the exhaust and the V0 space communicates with the exhaust side, the gas pressure at the exhaust side is higher, and a part of the gas flows back into the space V0, causing a sudden increase in the gas pressure. As the rotor continues to rotate, the gas is expelled from the pump. Roots pump in the pump cavity, there are two "8" shape of the rotor perpendicular to each other on a pair of parallel axis, by a transmission ratio of 1 of a pair of gear belt movements synchronous reverse movement of each other. In the rotor, the rotor and the pump housing between the wall to maintain a certain gap, you can achieve high speed operation.
- Q:Please give me professionals to calculate, the cylinder bore is 100 and the rate of 20m/s, the leakage can be ignored, but to the large flow pump!
- 2. displacement and flowDisplacement refers to the pump (or motor) every turn a week, by the size of the sealing chamber geometry variable discharge (or enter) the volume of liquid, commonly used unit is ml/r (ml / rev). Displacement can be changed as a variable pump (or variable motor), and the displacement can not be changed into a quantitative pump (or a quantitative motor).Actual flow is the amount of flow at the outlet (or inlet) when the pump (or motor) is operating. As the pump itself leaks, the actual flow is less than the theoretical flow. As the motor itself has an internal leakage, to achieve the specified speed, in order to compensate the leakage, the actual flow of input must be greater than the theoretical flow.
- Q:What is a feed pump?
- In general, high lift pumps are required with a front pump (which is similar to the feed pump of the landlord) or a low position;
- Q:What are the important parameters of the pump?
- The head is the unit weight of liquid pump pumping from the inlet of the pump (pump inlet flange) to the outlet of the pump (pump outlet flange) energy value. Effective energy is a Newtonian liquid through the pump unit is obtained. The N m/N=m, the height of liquid column pumping liquid used, referred to as meters.Speed nThe speed is the number of revolutions per unit time of the pump shaft. It is indicated by the symbol n. The unit is r/min.Cavitation allowance NPSHCavitation margin, also called net positive suction head, is the main parameter to indicate the cavitation performance. The cavitation margin has been expressed by delta H at homePower and efficiencyThe power of water pump usually refers to the input power, that is, the power transferred by the prime mover to the pump shaft, so it is also called shaft power. It is expressed by P;The effective power of the pump, also known as the output power, is expressed in Pe. It is the effective energy obtained by pumping the liquid out of the pump in unit time
- Q:What is the cause of the damage of pump bearings?
- In high-speed equipment, the most likely damage to bearings is high temperature.
- Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
- Centrifugal pumps require a vacuum to produce negative pressure, which allows atmospheric pressure to lift the water surfaceAxial flow pump impeller is thrust on water
- Q:The main factors affecting the performance of centrifugal pumps
- Revolutions required to have. It has the following meanings: 1, similar to the geometry of centrifugal pump, everywhere efficiency at the top of the similar condition; centrifugal pump 2, than the number of different, its geometry must be different than the number; the same pump, its shape is similar, but does not rule out the shape similar situation. The following factors are related to specific speed. The specific speed of centrifugal pump has nothing to do with the nature of the conveying fluid, but has a close relationship with the shape of the impeller and the performance curve of the pump. The pump with high specific speed corresponds to the highest efficiency when the flow rate is large and the head is small
- Q:How many kinds of pumps are available and the operating principles of various pumps?
- There are many kinds of pumps. There are different classifications according to different standards. If classified according to the principle of work, can be broadly divided into the following four categories:1, vane pumps: centrifugal pumps, axial pumps, mixed flow pumps, vortex pumps, etc.;2, displacement pumps: piston pumps, piston pumps, diaphragm pumps and so on;3, power rotary pump: screw pump, gear pump, etc.;4 、 special function: jet pump, water hammer pump, magnetic drive pump, etc.;
