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:What is the distance between the pump and the wall?

What do you mean by that? If your pump is parallel to the wall! Then, the wall of the pump near the wall is usually 500mm. This is an empirical data, considering the import pipe length, pump maintenance and motor heat dissipation and other aspects of the situation to determine. Dozens of pumps installed in our company are placed in this size! Hope to be of help to you.

Q:How high can the pneumatic diaphragm pump be?

Diaphragm capacity, high temperature, pneumatic diaphragm pump ability, high temperatureMany users do not know how high the temperature resistant diaphragm pump, diaphragm pump either electric diaphragm pump or pneumatic diaphragm pump products it cannot do without diaphragm attachments, diaphragm materials mainly fluorine rubber, rubber, rubber, polyether road three EPDM, PTFE several, if not considering the gas temperature resistant diaphragm made of stainless steel. The temperature to 600 degrees of diaphragm pump diaphragm pump, but must use the diaphragm, so the diaphragm pump can Naiduo high temperature depends entirely on the diaphragm was affected by temperature, following to share various diaphragm pump diaphragm material and different material temperature choice diaphragm pump product right:

Q:Please give me professionals to calculate, the cylinder bore is 100 and the rate of 20m/s, the leakage can be ignored, but to the large flow pump!

1. rpmOperating speed is the actual rotation speed of a pump (or motor) at work.Rated speed is the maximum speed that can operate normally for a long time under rated pressure. If the pump exceeds the rated speed, the work will cause insufficient oil absorption, vibration and noise, the parts will suffer cavitation damage, life expectancy.Minimum steady speed is the minimum speed allowed for normal motor operation. At this speed, the motor does not appear crawling phenomenon.

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: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 is the lift off the dead center point? This is a straight mark about the water pump. What is the function and the relationship between the design head and the pump head? ThanksWhat exactly is the dead point lift? What's the function of this indicator?

The dead point head is the measured head after the outlet valve is closed. Mainly on the lower reaches of the pump equipment, such as your dead center, the lift is 300 meters, that is, 3MPa

Q:Why should the pump be closed when the centrifugal pump is started?

Therefore to close the outlet valve, the pump during starting output water, the minimum pump power, when the pump reaches the rated speed, slowly open the outlet valve, gradually increase the flow of water, the motor current is gradually increased to the rated current.

Q:Is the flow meter in front of the pump or after the pump?

After the flowmeter is placed in the pump, it is better to add a pressure tank or a buffer tank, so that the flow meter will work better

Q:Attention should be paid to the use of pumps?

1, pump shaft packing completely worn, it is necessary to add in time, if you continue to use the water pump will leak. The direct effect of this is the increased energy consumption of the motor, which will damage the impeller. 2, the use of pumps in the course of a strong vibration, then must stop to check the reasons, or the same will cause damage to the water pump. 3 gear pump valve Water Leakage, some will use the soil into the water pump inlet tube, the water washed in the end valve, this is indeed undesirable. Because when the dry soil into the inlet pipe, when the pump started working, these dry soil will enter the pump, which will damage the pump impeller and bearings, which shorten the service life of the pump. When the valve Water Leakage must take to repair, if it is serious that it is necessary to replace the new. 4 after the use of pumps must pay attention to maintenance, for example, when the pump is exhausted, we should put the water pump who put clean, it is best to remove the water pipe, and then rinse with water. 5 water pump on the tape should also be written down, and then always flush, and then light out to dry, do not put the tape in the dark damp place. Water pump tape must not be stained with oil, not to tape coated with some sticky things.
