Q:Types and differences of pumps
Depending on the flow of the fluid, they can be subdivided into the following:Classified centrifugal axial flow type mixed flow tubular flow typeThe basic principle of impeller centrifugal force generated by the high-speed rotation of the fluid energy rotary vane extrusion propulsion of the fluid increases the pressure to get the energy mix and energy principle of centrifugal and axial and centrifugalSuch as: central air conditioning centrifugal fan, central air conditioning or cold storage axial flow water pump, mixed flow water pump, domestic air conditioner, indoor fanWorking principle of pump and fanI. the working principle of centrifugal pumps and fansThe centrifugal force generated by the high-speed rotation of the impeller fluid power, namely fluid through the impeller, pressure and kinetic energy can be improved, which can be transported to the height or distance. The impeller is arranged in a spiral shell, when the impeller rotates, the fluid axial inflow, and then turn 90 degrees into the impeller and the radial outflow impeller. Continuous rotation of the impeller inlet in the form of vacuum, so that the fluid continuously by the pump suction and discharge.
Q:What is the pump lift voltage? And how to suppress the pumping voltage rise?
The elevator is mainly used by the power grid through the rectifier, filter, inverter and other transmission to the motor. The motor in high speed when the brake suddenly, but the rotor of the motor with the load (production machinery) mechanical inertia, could not stop quickly, resulting in the back EMF (EU voltage) motor is in the state of power, the reverse voltage and torque original electric state torque instead, and the motor with brake strong torque, forcing the rotor to stop fast but usually AC-DC-AC converter is the main power AC/DC rectifier circuit is irreversible and therefore cannot go back to the grid, energy will be accumulated in the filter capacitor, produce pump voltage, this phenomenon of pump voltage converter has great destructive power.
Q:What is a vacuum pump for?
In fact, the vacuum pump and high Swiss fan, high Swiss high-pressure blower, high Rui high-pressure pump principle is almost the same
Q:Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines?
Unreasonable, easy to produce throttling loss, pressure loss, pressure reduction, easy to cause cavitation
Q:Why should the pump be closed when the centrifugal pump is started?
On the other hand, the water on the pipe of the inlet pipe of the pump is stationary before the pump is opened, such as the sudden acceleration, and the water behind it can not keep up, which will cause the pressure of the inlet to drop suddenly and vaporize the water, and the centrifugal pump will be evacuated. (because of the centrifugal pump is rotating centrifugal force generated by the pump, leaf water and steam driven (gas) quality is very light, according to F= Ma, the centrifugal force is small, the pump can not be water sent).
Q:If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?
Submersible pump even if it really leakage, it will not cause the fish electric shock. The so-called leakage is the submersible pump wire or shell broken, live parts and water contact, the most extreme test is a fire line directly into the fish tank
Q:Excuse me, what is the water pump from the lotus root?
Submersible sewage pump with septic tank, outlet pipe automatic coupling installation, dipping down can be.
Q:What are the conditions required for hydraulic pumps to complete oil absorption and compression?
There must be one or more sealing volumes, and the volume of work is variable;
Q:Working principle and structure of external gear pump
The principle of the gear pump, gear pump structure consists of two gear mesh together with each other, and composed of pumps known as gear pumps. It relies on the gear teeth meshing space change in volume to transport the liquid, it belongs to the rotary pump, also can be considered as a volume pump. There are many kinds of gear pumps. According to the meshing mode, it can be divided into external gear pump and internal gear pump. According to the tooth shape of gear, it can be divided into positive gear pump, helical gear pump and herringbone gear pump.
Q:Brief description of centrifugal pump on / off operation
Two, centrifugal pump start(1) the pump entrance valve fully open, start motor, outlet valve fully closed, fully check operation of pump.(2) when the pump outlet pressure is higher than the operation pressure, the outlet valve is gradually opened to control the flow and pressure of the pump.(3) check whether the motor current is within the rated value, such as the pump in the rated flow operation, and the motor overload should stop the pump inspection.
