Q: What is the pump lift voltage? And how to suppress the pumping voltage rise?: [pump voltage] when braking, in the motor winding series resistance, motor equivalent to the generator, the energy will be converted to electric energy consumption in the series resistance. This method is widely used in all kinds of motor braking, and frequency conversion control is also used. From high to low (zero speed), then the electrical frequency changes quickly, 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,

Q: If the suction pump does not have enough suction range, you need to add a vacuum pump to increase the suction stroke. How do you install the suction pipe of the vacuum pump? Water pump impeller is not closed, it is normal that the vacuum pump is unable to pump suction pipe to a vacuum, is it because the water pump outlet pipe connected to the role of the check valve? But the water pump, outlet pipe, check valve sealing performance can achieve the function of non leakage?: The role of the check valve:"[the water pump impeller is not closed" refers to the pump suction pump before the water without water inlet pipe and water outlet pipe gas should be connected] is a connector, a connector, still can make the level surface, in order to prevent the water flow along the pipe, until it reaches the level of the flush, then increased check valve.

Q: The distance from the pump button to the ground: Yellow warning pop-up, indicating that the fire control room has issued alarm information, fire alarm controller (commonly known as the alarm host)

Q: Does vacuum pump oil belong to dangerous goods?: Of flammable substances, but not included in dangerous goods!Does not belong to dangerous goods,

Q: Operating procedures for measuring pumps: Pressurization(1) for the discharge pressure below 2.0MPa, then the pump stroke length should gradually increase, each increase of 20%, to maintain 15 minutes.(2) for the discharge pressure greater than 2.0MPa, you need a special pressure, to ensure that the pump discharge pressure gradually increased, each time for the final row pressure of 20%.(3) when the pressure is not increased, the stroke of the pump is gradually increased by 20% strokes per time.Note (1) when pressure is applied, the pressure gauge should be observed at the side of the loading side (slow motion)(2) check ammeter, forbid overload

Q: Rules for operation of centrifugal pumps: 3, start the pump, wait until the speed reaches the normal speed, slowly open the outlet valve, observe the ammeter at the same time, and control the current in the rated current range of the motor.4, the operation requires smooth operation of water pumps, no abnormal noise, no pressure fluctuations. The abnormal situation should be stopped in time.

Q: Water pump does not produce water, what are the reasons?: The reason why centrifugal pump does not produce water:1. pump inlet or sink, water tank water shortage.2. water pump pipe blocked or valve not open.

Q: What does centrifugal pump mean horizontally?: Centrifugal pump: centrifugal pump is a centrifugal force on the impeller rotates to transport liquid pump. Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work. The pump before starting to pump shell and the water pipe filled with water, and then start the motor, the pump shaft to drive the impeller and water do high-speed rotation, centrifugal water movement, was thrown to the outer edge of the impeller, the pressure water pipeline flow through the volute pump into the pump shell.

Q: Suction stroke and lift of water pump: For example: there is a kind of water pump, the model is called "BSP" series, the volume is not large, but the nominal suction process can be 4 meters, it can not add water to 4 meters, it is considered to be relatively high in the micro pumpIn micro pumps, not all pumps have self-priming capacity ("suction stroke")Some centrifugal pumps there is no self-priming ability to use must first do add water. Although some micro pump with self absorption capacity, but "suction" are often the subject of "and the water inlet pipe in all air, can smoke the vertical height of water gap, even only half not so. The pump selection, the absorption process is a relatively important parameter.

Q: What does "dual purpose" of water pump mean? Please expert advice: 1, if the water pump in the process of a strong vibration, then must stop to check what is the cause, otherwise it will cause damage to the water pump.3, when the pump valve Water Leakage, some people will fill with dry soil to the water pump inlet pipe, the water washed in the end valve, this is indeed undesirable. Because when the dry soil into the inlet pipe, when the pump started to work, these dry soil will enter the pump, then it will damage the pump impeller and bearings, thus shortening the service life of the pump. When the valve Water Leakage must take to repair, if it is serious that need to replace the new.
