Scientific instruments are tools for precision measurement, and their precision and reliability must be an order of magnitude higher than the object being measured. Therefore, although there are not as many components as airplanes, the systematic design is also beyond imagination. The chromatographic column, as a consumable, is a separation center, just like the heart. High pressure, tightness and flow rate stability are required. And the oven needs to be kept at a constant temperature. To prevent leakage, maintain constant temperature, pressurized flow, every link, can not be slack. For materials, seals, and fluid mechanics, a high foundation is required.

The method for checking whether the instrument leaks: pinch off the external vacuum skin tube, and observe whether the vacuum gauge on the instrument can keep the instrument leak-free for five minutes. If there is air leakage, check whether the sealing ring on each sealing joint and rotating shaft is effective. On the contrary, the instrument is normal to check the vacuum pump and vacuum pipeline.

The 1. 2XZ series vacuum pump is a two-stage direct connection structure. The direct connection vacuum pump is one of the basic equipment used to pump the gas in the sealed container. It can be used alone, can also be used as booster pump, diffusion pump, molecular pump and other pre-pump, maintain pump, titanium pump pre-pumping pump. Its working performance consists of two parts: high-pressure stage and low-pressure stage. Its suction port is connected with vacuum equipment. During operation, a large amount of gas in the container is sucked and discharged. When the equipment obtains vacuum, the high-pressure stage exhaust valve is closed. The gas at the inlet of the high-pressure stage will be transferred to the second stage, and a certain vacuum can be obtained through the second-stage suction and discharge vacuum equipment. The pump has high speed and small appearance, compact structure, convenient mobility work.

2. product features

1. Small size, light weight and low noise.

2, can be in the ambient temperature 540 range, the inlet pressure is less than 1.3X103 Pa conditions allow long-term continuous operation.

3. A gas ballast valve is provided to remove a small amount of water vapor.

4. It is equipped with automatic anti-oil return double insurance device (except 380V).

3. scope of application

1. It can be used for electric vacuum device manufacturing, thermos bottle manufacturing, vacuum welding, printing, blister, refrigeration equipment repair and instrument matching.

2. Laboratories and laboratories of aerospace, semiconductor, coating, food packaging, drying, refrigeration, scientific research, medical, electronics, chemical, pharmaceutical and other professional units, colleges and universities and other departments.

3, the pump is not suitable for pumping in addition to the metal corrosion, the pump oil from the chemical reaction, containing particles of dust gas, and oxygen is too high, there are explosive, toxic gas.
