- Q: Why does the centrifugal pump close the pressure to start?
- The motor power is selected according to the rated flow of shaft power points plus 15 to 25%, if the outlet valve is fully open to start, the pump flow may deviate from the amount of fixed lot, pump efficiency also reduces a lot, resulting in shaft power greater than the motor power caused by tripping even burned electric machine.
- Q: Working principle and diagram of axial piston pump with pressure compensation variable
- The size of the outlet flow pressure compensated variable displacement pump with outlet pressure of approximately in a certain range according to the constant power curve. When the pressure oil from the main part of the channel (a), (b), (c) into the inferior vena cava (d) variable shell, oil by the channel (E) respectively into the channel (f) and (H), when the spring force is greater than the oil (f) into the lower end of the piston ring servo hydraulic thrust area when the oil liquid (H) to the chamber (g), push the variable downward movement of the piston, the pump flow increases. As for the hydraulic servo piston end thrust force ring shaped area is greater than the spring when the servo piston moves upward, blocking channels (H), the (g) (I) through the cavity of the oil cavity pressure relief, at this time, the piston moves up, the variable head angle decreases, the pump flow rate decreases.
- Q: Fire control center manually start the fire pump directly, multi line control, called straight up line NHKVV-7*1.5, my understanding is: straight line from fire control center
- Multi line linkage NHBVR-4*1.5 is a positive pressure blower and smoke exhaust machine fire fighting equipment
- Q: What are the starting and stopping procedures for centrifugal pumps?
- The use of centrifugal pump can be divided into three steps, namely, start, run, stop.Start: you should do the following preparation before starting:(1) check the water pump equipment in good condition.(2) the bearings are filled with oil, the oil level is normal, and the oil quality is qualified(3) all the inlet valves of the centrifugal pump are opened.(4) pump water injection or vacuum pump diversion (except for flow), open the vent valve exhaust.(5) check the leakage of shaft seal. It is advisable to fill the seal with a little drop of water.(6) the motor rotates in the right direction.
- 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: 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: Metering pumps related matters
- Rotate to stroke length 100% position. This allows the kit to rotate to the back of the drain hole and align the bottom of the pump. Adjust the hydraulic end and diaphragm to the proper position during the pump operation.The duration of the pulse may not be long enough for the reaction time. With respect to the standard pulse width 80msec, the flow monitor pulse width expansion can be activated, increasing the pulse width to 300msec. Activate the smart switch, remove the cover fixed circuit board, remove the jumper X-1. This activates the extended function and allows more time before the failure instructions.Metering pump installed from the exhaust pump head, the use of self suction liquid imbibition. Keep the suction line as short as possible.
- Q: What do you mean by the self coupling device on the pump?
- Overview of GAK self coupling device:The utility model relates to a GAK self coupling device, which is an automatic butt joint between a water outlet flange of a submersible electric pump and a water outlet pipe system.In the above additional coupling flange and the water outlet pipe seat inlet flange with a pair of wedge card, under the additional coupling flange and the water outlet pipe seat inlet flange and a pair of wedge cards in a wedge seat below the outlet pipe inlet flange card is made of elastic steel plate is fixed on the lower side of the seat pipe inlet flange. When the submersible pump water falling from above, Kaxianka additional coupling flange at the top of the wedge wedge and seat card outlet pipe above the inlet flange together, in the role of the dignity of the pump and submersible inclined wedge clamp, two flange will be put together in a pair of wedge under additional coupling flange and the water outlet pipe seat inlet flange the card will be in the elastic plate under the action of automatic card together. The utility model can solve the problem that a large amount of water leakage between the two flanges of the coupling is saved when the automatic installation and disassembly of the electric submersible pump is convenient, thereby saving energy.
- Q: How to maintain and repair the booster pump of pipeline pump?
- Installation and use1. use rubber washer and bolt to connect the pump flange at both ends and the pipe flange. In order to use and maintenance convenience, in the pump inlet and outlet pipelines should be installed with a regulating valve.2. open the inlet control valve, so that water into the pump, in order to keep the cavity filled with liquid (otherwise it will damage the seal), close the outlet valve.3. turn on the power and make sure the correct turn.4. make sure the pump starts and runs after turning.5. adjust the opening of the outlet valve so that the pump runs near the design point, depending on the rated flow and lift of the pump. [for this reason, it is better to place a pressure gauge near the outlet flange). Note: this pump is strictly prohibited to run without water, so as not to damage the seal.
- Q: Why adjust the centrifugal pump outlet valve can adjust the flow? What are the advantages and disadvantages of this method? Is there any other way to regulate the flow of the pump?
- The centrifugal pump at a fixed speed, the head is fixed, adjust the outlet valve to adjust the diversion area
