- Q: Fire hydrant pump button, under what circumstances do not need to install?
- The installation of hydrant pump buttons depends on the type of water supply:(1) municipal water supply; (in this case, do not have to install)(2) there is a fire pump; (must be installed)
- Q: What are the basic technical parameters of the pump?
- The effective power of pump and output power, with Pe said. It is the effective energy per unit time from the pump in conveying out liquid obtained in the pump. Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and the acceleration of gravity. Is to obtain the output from the pump in unit time of liquid effective energy - efficient pump power: Pe= P gQH (W) = QH (W) - P - density of liquid pumping (kg/m3); severe gamma - pump for transporting liquid (N/m3) - Q (pump flow; m3/s; H) - pump head (m); G (m/s2). The acceleration of gravity P axle power and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said. Selection of related pumps:
- Q: Operating procedures for measuring pumps
- start-up1. Adjust the stroke indication to zero by adjusting the nut or handle with the rotary stroke.2 open the outlet valve.3. Open the inlet valve, pump, exhaust from the high point, exhaust from the relief valve, the breather valve.4, point motor, check the operation of the pump.5. Start the motor.6, without pressure on the premise, every 15 minutes to improve the stroke 20%, if there is no pressure, do not substantially improve the stroke.Note: (1) whether the sound or vibration of the pump is abnormal (2), whether the stroke adjustment is automatic or not
- Q: What are the characteristics of a vertical multistage centrifugal pump?
- A liquid that is primarily diluted, clean, non corrosive, explosive, or similar to water but contains no solid particles or fibers. Because of its high flow and large lift, it is widely used in fire fighting, water supply and air conditioning unit cooling water transportation in high-rise buildings.
- Q: Pump operator's responsibility 10Sharing the rules, responsibilities, etc..
- 1., consciously abide by the traffic control department management rules, to achieve civilized driving, safe driving.2. responsible for the daily maintenance, cleaning and cleaning of the pump truck, and ensure the equipment is in good condition.
- Q: I want to know the concrete under 60 type pump performance, it is mainly the pump long spiral bored piles, such as the diameter of the pump, transportation distance, pumping height and so on, thank you!
- Maximum theoretical vertical transfer distance is m 270Maximum theoretical level conveying distance m 1200Distributing valve form S pipe valve (whole casting)
- Q: Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?
- Have to know the ratio, pneumatic pump, if high pressure, you can have 2:1,3:1
- Q: Why can't the centrifugal pump pump the vacuum?
- Characteristic equation of centrifugal pumpStudy the effect of fluid on centrifugal pump to obtain energy.The experimental condition of u is that the ideal fluid of unit weight bends the flow between blades at infinity.U investigated the mechanical energy balance of the fluid between the adjacent two inlet and outlet sections, that is, the relationship between theoretical pressure head and theoretical flow.
- Q: Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.
- If the water pressure is not enough, the pump can not start, then it must be wrong. Because if the water pressure is not enough, the pump should be running automatically. It's just because the water pressure is not enough.
- Q: No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same, how to choose the control cabinet?
- Non negative pressure variable frequency water supply means no negative pressure superposed water supply equipment. When running, it is connected directly to the water supply pipe. Always test the pressure of tap water pipe network and water supply pipe network pressure control system, when the water pressure is lower than the pressure required by the user, the frequency conversion device based on water automatically control the pump speed through the steady flow compensator of water balance, maintain a constant pressure water supply. In the multi pump system, the control system can automatically dispatch the water pump according to the water consumption. It can balance the working time of the pump and ensure the pressure of the water supply. When the water supply pressure satisfy the required pressure, the system automatically stops the pump by the external water supply pipe network directly.
