Qué relé hace el micro vacío bomba uso para cortar el poder?

Micro vacuum pump is a small vacuum pump commonly used in laboratory, medical equipment, instruments and other fields. Its working principle is to extract gas by mechanical means, and will pump the gas out of the machine, so as to form a vacuum. The control system is usually implemented by a relay. The relay is an electrical control device that can use the principle of electromagnetic induction to control the switch of large current. In a miniature vacuum pump, the role of the relay is to convert the control signal into the action electrical signal of high current, so as to control the start-stop and operation of the vacuum pump. When choosing the relay used for the micro-vacuum pump, many aspects need to be considered, including the relay capacity, reliability, operation mode, installation mode and so on. If the selected relay capacity is too small, the selected relay may not meet the starting current of the vacuum pump, failing to work properly; if the capacity is too large, it may waste electricity and increase the equipment cost. At the same time, the reliability of the relay is also very important, if the relay is easy to damage or failure, it may affect the normal operation of the micro vacuum pump.

There are some questions in the micro vacuum pump industry, can you use a mechanical relay to control the micro vacuum pump power off? From their working principle, it is best to use solid-state relays, not mechanical relays. Because the mechanical relay and other machinery in the connection moment, there is a spark process, but as long as the "reliable" contact with the pump motor can be; will not necessarily cause the pump motor burned. Mainly is to avoid power, hand motor wiring, which may lead to bad contact action or behavior. Not to say that the solid state relay, mechanical relay should also be no problem, but the solid state relay is electronic style, more reliable than mechanical type, causing the probability of burning is much smaller. Solid state relay is a new type of electric control element, which is different from the traditional electric relay in that it has no mechanical contact, using semiconductor devices as a switch, has many advantages of fast response, no noise, no arc, long life and so on. In the micro-vacuum pump control system, the solid-state relay control circuit is safe and reliable. Compared with the traditional electrical relays, the solid state relays have no mechanical contacts, so there is no arc and spark phenomenon caused by the contact wear, which makes the control circuit more safe and reliable. Adaptation is good. Micro-vacuum pumps are usually driven by alternating current, while solid-state relays are more compatible with alternating current, which can not only cope with voltage fluctuations and current changes, but also adapt to different frequencies of alternating current. The reaction speed is fast. Solid-state relays use semiconductor devices as switches, so the response speed is very fast, and can be turned on and off in an instant, so as to ensure the stability of the working state of the vacuum pump.

Para ejemplo, el micro vacío bomba VAP-2703, el pico flujo es 8 L/min, el presión negativo puede alcanzar-0.075 MPA, el velocidad regulación rango es sobre 60-100% (bajo luz carga), pertenece a la corriente micro vacío bomba ambos alto negativo presión, ajustable velocidad, pequeño volumen productos, bolsillo volumen, solo 1 / 2 puño grande. Adopte importado alto grado motor , súper larga vida útil , ultra bajo interferencia.

DC micro vacuum pump VAP-2703, the iconic parameter of high-end micro vacuum pump- "frequent start and stop parameters" ultra high, the imported full version of the highest frequent start and stop times up to 1.8 million times, especially suitable for large load, frequent start and stop or long-term day and night continuous operation and other bad conditions. Use better raw materials, equipment, process to manufacture pump parts, multiply the life; all moving parts use durable products, with imported high quality brushless motor, improve pump life. For the "PWM speed regulation", "motor FG feedback" and other signal lines (simplified version no FG feedback function), truly "full function"; through the "duty cycle" to adjust the motor speed, change the pump output flow, fast and slow, arbitrary; at present, even the foreign famous brand of micro vacuum pump can not do this. It can run continuously for a long time day and night, with low noise; the exhaust end can carry large load and even blocking; the exhaust end shall not have damping element; no oil and maintenance free. The internal use of precision control circuit, is not allowed to have similar live touch, plug and other operations, otherwise it is easy to cause the pump motor burned. So if you need a relay to control the power off of a brushless micro water pump, we recommend using a solid state relay, not a mechanical relay.
