Common sense maintenance of gas ring vacuum pump

High efficiency, low energy consumption (the gas ring vacuum pump has a conservative design in the high pressure range, and the gas ring vacuum pump can still operate safely when the use situation changes);

Low noise (use Shanghai Haoguan low noise motor direct drive to reduce running noise);

Sturdy structure (the air surface is made of aluminum alloy and milling alloy, which is different from the general aluminum or iron casing, which is more durable);

Scope of application (gas ring vacuum pump has many specifications, high pressure and high air volume series, which can be flexibly selected);

Zui high quality (with nearly 30 years of manufacturing experience, with strict quality control, so that all parts can achieve high quality);

Blow and suction dual function (one machine for dual use, you can use suction, you can also use hair dryer);

Low wear and long life (the mechanical wear of the gas ring vacuum pump is small, because there is no other mechanical contact part except the bearing);

Easy to install (gas ring vacuum pump can be installed in horizontal or vertical direction);

Clean and non-polluting (less oil or no oil operation, the output air is clean, when the impeller rotates, it does not contact any other parts, no lubrication, so it can ensure that the gas ring vacuum pump is not dyed.);

High performance (except for the impeller, no other moving parts, use * and good heat dissipation of the outer bearing);

Low vibration (high mechanical precision, the rotating parts are designed with extreme precision, testing, calibration, and low vibration rate);

The gas ring vacuum pump is also called a high pressure fan, which is different from the general centrifugal gas ring vacuum pump.

The gas ring vacuum pump has two functions of air supply and suction, and the gas passed through is oil-free and dry, and is suitable for auxiliary equipment of many mechanical industries.

Maintenance and maintenance methods for gas ring vacuum pumps:

1) The motor is directly connected to the impeller and belongs to high speed. The bearing needs to be regularly maintained with grease to prevent damage (including the bearing of the impeller).

2) The shaft power of the motor is proportional to the pressure. In order to prevent the long-term ultimate pressure from increasing the shaft power, the motor load is too heavy. The pressure relief valve is often used. It is an unloading valve when the gas ring vacuum pump is used. After the pressure exceeds the pressure set by the pressure relief valve, the pressure relief valve automatically opens to relieve excess pressure, thereby protecting the motor of the gas ring vacuum pump.

3) The internal mechanism of the gas ring vacuum pump is relatively tight, and the gap between the impeller and the casing is small, so it is necessary to filter debris and dust. For sundries, it is common to install a fine filter on the air inlet, dust, and often use a filter. It is based on different use sites, often using different filter precision filter cartridges, different filter cartridges have different maintenance methods and service life, you need to ask when ordering.

4) In some special occasions, special protection is needed: for example, when using in a sealed environment, pay attention to ventilation and heat dissipation; when the ambient temperature (the intake air temperature is relatively high), pay more attention to ventilation and heat dissipation, or choose to allow A gas ring vacuum pump with a high inlet air temperature.

The working principle of the gas ring vacuum pump:

When the impeller rotates, the gas ring vacuum pump forms a series of spiral motions due to the centrifugal force. The gas rotating motion between the impellers accelerates and draws gas outside the pump body from the air intake port, and the gas enters the outer air ring and returns to the base of the blade by the pressure difference to form a strong air flow. In this way, the gas is moved in the spiral direction in the gas ring to achieve the purpose of pressurization. After the gas moves to the exhaust port, since the pressure is greater than the system pressure, the gas is quickly discharged. The function of the Shanghai Haoguan gas ring vacuum pump for suction and air supply is widely used.

Freeze Dried Fruit

The freeze dried food is the abbreviation of vacuum freeze-dried food, also known as FD food. Due to the special place of freeze-drying.Therefore, the color, flavor, nutritional composition, appearance and shape of the original fresh food can be maintained to the greatest extent; In addition, freeze-dried products can be stored at room temperature for more than 5 years without preservatives, and the finished products are light and easy to carry and transport. It is an excellent method for processing tourism, leisure and convenient food. Freeze dried food, a former aristocrat known as astronaut food, has quietly entered people's life.

Freeze dried fruit uses the vacuum freeze-drying method of the freeze dryer to freeze the water in the fruit in advance, and then sublimate the frozen water in the fruit in the vacuum environment to obtain the freeze-dried fruit. In short, extract the water in the fruit at low temperature to retain its original nutrition.

Freeze dried fruit is fast freezing and vacuum ice dehydration. It preserves the original color, aroma, taste, nutrients and the appearance of the original materials. It has good rehydration and does not contain any additives. It is an ideal natural hygienic food.
