Q:How to adjust the minimum starting air pressure of the air pump?
1 、 adjust the pressure limiting valve. If the spray model can use airbrush adjustable on the line, the tail of the control knob when the spray liquid area, large tone is a little loose, the middle knob control of volume.2, pump (Q. B ng air pump), namely "air pump", a device for removing air or add air from the enclosed space from a closed space. The air pump is divided into an electric air pump and a manual air pump. Electric air pump. An electric pump powered by electricity; produces air pressure by constantly compressing the air through electricity. Applications: pneumatic glue, car inflatable, etc..
Q:Does the high pressure air function replace the air pump?
High pressure air can not replace the air pump.Blowers and air pumps are not the same equipment. Said the first pump, also known as air compressor, compressed air can be stored, the pressure can be adjusted, the use of wide area; although can store a certain pressure value of the compressed air, but not a constant output value of the air pressure, can output large flow of air, the device itself does not have long-term operation ability, is described under start compression. To a certain pressure value from the stop, and then use the compressed air, emptying into the lowest pressure set value from the start to compression.There are many kinds of blower, but the characteristic is the air which can output constant pressure value. It has the ability to run for a long time, the pressure can be adjusted, and some of them are not suitable for the process of frequent starting and stopping. For example, the centrifugal blower is almost the same as the household, and the different types of blower used in the blast are very different, and the management is different.Under the design condition, the blower with the wind pressure of 30kPa~200KPa or the compression ratio of e=1.3~3 belongs to the category of high pressure blower. At present, the air ring vacuum pump is generally classified as a high pressure blower in the industry. High pressure blower, also known as high-pressure fan, is different from the general centrifugal high-pressure blower.The high pressure blower is small and easy to carry. Besides the impeller, the high-pressure blower has no other moving parts, and the impeller is directly connected with the motor without gear or drive belt. Therefore, the utility model has the advantages of high reliability and almost no maintenance.
Q:How do I adjust the air pressure of the air pump when I spray the model?
Airbrush not spray, the switch is open, this time open the valve, automatic constant pressure deflated pointerAt work, the pressure relief valve automatically closes, the pressure pointer up, and use the pressure regulating valve to control the pressure, after a period of work, the motor overheating, automatic stop ~!Without automatic stop, adjust the pressure with a pressure regulating valve, work for half an hour to about an hour, when the motor overheating, it will shut down. After the cooling in the open ~ ha ha, new guys, come on, and remember to give me points ah!
Q:How to install the inside and outside chamfer of piston ring of air pump?
The piston ring is chamfered outward so that the oil is returned to the cylinder when it is turned back
Q:How can I solve the water in the air pump?
Air pump water is normal, it is your air pump drain valve is not easy to use, check it will be good.
Q:Can the vacuum suction pump be frequency converter?
Addition can be added, but the ordinary frequency converter uses PID operation to achieve the purpose of protecting the motor, but the control loop is complex, and the control accuracy is not high, and the conversion is complex. It is impossible to distinguish the motor blocking current and the normal load current, which may cause the motor to work in a locked state for a long time, resulting in the burning of motor.Wei Gen AC80 vector inverter vacuum pump special program does not need to add any external equipment, the inverter itself can achieve accurate control of motor current and speed. Wei Gen inverter can quickly identify the blocking current and load current, can immediately identify and alarm the stop, to prevent further expansion of the fault.
Q:10Kg air compressor is equivalent to the big air pump
The amount of air determines the size of the air compressor, and the size of the pressure does not determine the size of the compressor.Air compressor: an air compressor is a device for compressing gases. The air compressor is similar to the pump. Most air compressors are reciprocating plugs, rotating blades, or rotating screws. Centrifugal compressors are very large applications.
Q:The difference between air pump motor 550W and 750W
This difference in power is the main difference in the performance of the air pump, which is different from the output of the gas under the condition of the gas pressure output. 750W is definitely higher than 550W.
Q:Is it better to use air blower or air pump hot air gun for mobile phone?
In fact, repair the phone, buy a fan type hot air gun can be!
Q:Why does the motor burn when the pump is powered on?
Motor power is not enough, overload is sure to hot, and that the motor power is enough, but the voltage level will affect the motor hot.The current flowing through the coil, current thermal effect, the greater the load of thermal effect is larger, there is a pump stator iron core, coil current, electric current produces a magnetic field, the magnetization, the magnetization is alternating magnetization, will produce alternating magnetic reluctance, will produce heat, core magnetization, core surface will produce eddy current the vortex core heat.The air pump (Q. B ng air pump), namely "air pump", a device for removing air or add air from the enclosed space from a closed space. The air pump is mainly divided into an electric air pump and a manual air pump. Electric air pump. An electric pump powered by electricity; produces air pressure by constantly compressing the air through electricity. Mainly used in pneumatic rubber, car inflatable, etc..
