Примечание:
Примечания к номеру модели: “F” означает фиксированную скорость, “V” — VSD. Из-за потенциально различной скорости вращения двигателей расход воздуха при фиксированной скорости представляет собой минимальное значение в диапазоне (т. е. 30 кВт, 8 бар, 5,67 м³/мин), в то время как VSD может достигать максимального значения при полной нагрузке.
Стандартное напряжение 380 В (+/-10%), 50 Гц +/-2%, а также доступно для индивидуального напряжения 220/380/440/460 В/60 Гц.
В случаях повышенной высоты над уровнем моря, экстремальных температур, чрезмерной влажности, сильного запыления или любых других сложных условий эксплуатации мы можем предложить индивидуальные конструкции продуктов, отвечающие вашим конкретным потребностям. Возможна индивидуальная настройка в соответствии с вашими уникальными требованиями.

The piston of pneumatic valve
The piston of pneumatic valve with integrated positioner for control applications with neutral to highly aggressive media. The straight design enables a highly efficient and very simple insulation of the valve body as well as the welded-on pipeline.
Inlet control valve
The intelligent control valve is mounted on the vacuum pump, to adjust the degree of opening automatically, to ensure that the main host has a minimum vacuum degree, to ensure that the lubricating oil circulation. The suction loss is lower and helps improve overall efficiency of the vacuum pump. If a sudden power failure or shutdown occurs, air intake will close automatically to prevent oily discharge.

Часто задаваемые вопросы
What is a vacuum pump?
A vacuum pump is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container and obtain a vacuum. In simple terms, a vacuum pump is a device that improves, produces, and maintains a vacuum in a closed space using various methods. It is widely used in industries such as metallurgy, chemical engineering, food, and electronic coating.
Например, одноступенчатый винтовой компрессор: давление на входе составляет около 1 бар атмосферного давления, сжимается ротором до давления на выходе 8 бар, степень сжатия в процессе сжатия составляет 8/1, то есть степень сжатия одноступенчатого компрессора составляет 8. В то время как давление на входе двухступенчатого компрессора составляет около 1 бар атмосферного давления, сжимается ротором первой ступени до давления на выходе около 3 бар, а затем поступает во второй ротор для сжатия, чтобы повысить давление до требуемых 8 бар. Степень сжатия ротора первой ступени низкого давления составляет около 3, а степень сжатия ротора высокого давления второй ступени составляет 8/3 ≈ 2,67, т. е. степень сжатия второй ступени составляет около 2,67. Максимальная степень сжатия двухступенчатой системы роторов сжатия составляет около 3.
What are the key points for vacuum pump selection?
When selecting a vacuum pump, there are several key points to consider. First, the pump’s ultimate vacuum and working pressure should meet the requirements of the equipment, with the ultimate vacuum being one to two orders of magnitude higher than the working vacuum. The pump’s working point should also be within its stable pressure range. Second, the pump’s exhaust capacity should be sufficient to remove all gases produced during the vacuum process. Third, multiple pumps may need to be combined to meet specific requirements, such as pre-vacuum or supplementary pumping. Fourth, if the equipment requires oil-free operation, oil-free pumps such as liquid ring pumps, claw pumps, or screw pumps should be selected. However, if cost is a factor and strict oil-free requirements are not necessary, oil pumps can be used with additional measures to prevent oil contamination. Fifth, the composition of the gas being pumped should be considered when selecting a pump, with appropriate pumps chosen for gases containing vapor, particles, or corrosive substances. Auxiliary equipment such as condensers, dust collectors, and anti-corrosion treatments may also be necessary. Finally, other factors such as back pressure at the exhaust port, motor power, price, and after-sales maintenance should also be taken into account when selecting a vacuum pump.
What are the requirements of the chemical process for the vacuum pump?
In order to meet the demands of harsh chemical processes with long operating cycles, vacuum pumps must first and foremost be reliable, durable, and have stable performance. Additionally, they must possess the following characteristics:
Firstly, it must be able to handle various solvents without causing damage to the pump. Secondly, it should not cause pollution to the environment or the process itself. Thirdly, the production of waste should be minimized as much as possible. Fourthly, the vacuum pump must be corrosion-resistant. Fifthly, it should be able to handle flammable gases or vapors. Lastly, it should be able to suction liquids without damaging the pump.
Next, check the oil level and look for any leaks or obstacles around the machine. If it’s a water-cooled machine, open the cooling water valve and pump, and confirm that the water pressure is normal. Finally, turn on the power and start the machine. If it has been idle for a while, start it a few times before running it continuously to avoid unnecessary malfunctions such as overheating or overload.
