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: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:Must the water pump in the tank be all soaked in water?
Need a submersible pump in the water, but it is not entirely like this, I have to work for a long time no problem in water, but there is a problem you should pay attention to the water pump, at least in half, or stop when the smoke is not on water.
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:How is the pump level of submersible sewage pump determined?
Pump water level must be higher than the water pump top, so that the motor running in the lower water temperature cooling environment, otherwise long-term operation will burn the machine
Q:The difference between diaphragm pumps, vacuum pumps and centrifugal pumps
The diaphragm works by changing the size of the diaphragm. When the cup is covered with an eraser and the edge is airtight, then pressing the rubber or pulling the rubber outward will make the pressure in the cup increase or decrease. Use this principle, in the pressure of an hour from a hole suction medium, when the pressure is large, from another hole extrusion medium, so as to achieve the purpose of conveying.
Q:What should be used to pay attention to the use of mechanical pumps?
When opening the pump, first close the outlet valve, lift the pressure, then open the outlet valve again, pay attention to the flow of the motor.
Q:How should the water pump be installed?
(8) check the suitability of the foundation and whether the size of the foundation corresponds to the size of the pump.(9) find the position of positive pump and motor, pump set and anchor bolt and the inlet and outlet flanges, to ensure that the flange torque of the pump conforms to the standard. Check the inlet and outlet piping before alignment. Make sure the weight of the inlet and outlet pipe does not exert force or torque on the pump. When looking for, should also pay attention to eliminate the pump rotor movement, so as to avoid the end gap error. If checked after the pump is working, it should be carried out under cold condition. It is important to draw attention to the fact that the pump set of the complete set of factory is only rough looking (checked with a ruler) when it is shipped. It may cause displacement when it is transported.
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:Is vane pump good or gear pump good?
The main working parts of vane pump is provided with a plurality of sliding vane rotor, when the rotor rotates, the eccentric configuration of stator cavity contour or rotor, blade sliding slot in leaves due to volume changes, resulting in the suction effect. The similarities are: 1, rotary type positive displacement pump has self-priming ability, but are not allowed to do; 2, with continuous flow pulsation, but also have flow and pressure; 3, the theory of flow is determined by the working parts of the size and speed, has nothing to do with discharge pressure; 4, rated discharge size, pressure and working parts mainly depends on the pump speed is independent of the sealing parts and bearing capacity; differences: 1) gear pump structure is more simple, reliable, low price; vane pump has complicated structure and high manufacturing precision parts, the blade is easy to get stuck, more sensitive to the oil clean degree and viscosity.
