Small and medium-sized culture pond. Vehicles and ships transport live aquatic products and no electricity in the area of aeration, but also as an industrial blowing air source.

 1. The main characteristics of vacuum adsorption high-pressure fans for printing machinery:

High performance (no other moving parts except impeller, precision outer bearing with * and good heat dissipation);

Clean and pollution-free (high-pressure fan with little oil or no oil operation, output air is clean, impeller rotation, not in contact with any other parts, free of lubrication, so can ensure that high-pressure fan pollution-free);

The mill structure is strong (the wind surface is made of aluminum alloy and milled alloy, which is different from the general aluminum shell or iron shell of the high-pressure fan, more durable);

High efficiency, low energy consumption (high pressure fan in the high pressure range has a more conservative design, in the use of changes in circumstances, can still operate safely);

Scope of application (high pressure fan specifications, high pressure and large air volume series, flexible selection);

Small loss, long life (high pressure fan mechanical wear is small, because in addition to bearings, no other mechanical contact parts);

Easy installation (high pressure fan can be installed in any horizontal or vertical direction);

Low noise (low noise motor direct transmission, reduce operating noise);

Low vibration (high mechanical precision, rotating parts are extremely precise balance design, testing, calibration, low vibration rate);

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

Blow suction dual function (one machine dual-purpose, can use suction, can also use blowing);

Second, the engraving machine vacuum adsorption high pressure fan maintenance and maintenance methods:

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

2) In some special occasions, special protection is also needed: for example, when used in a sealed environment, pay attention to ventilation and heat dissipation; when the ambient temperature (when the intake temperature is relatively high), pay more attention to ventilation and heat dissipation, or choose a high-pressure fan that allows a higher intake temperature.

3) The mechanism inside the vacuum adsorption high-pressure fan is relatively tight, and the gap between the impeller and the casing is very small, so it is necessary to filter debris and dust. For debris, generally installed in the air inlet fine filter, dust, often used is a filter. According to different use sites, it often uses filter elements with different filtration accuracy, different filter elements have different maintenance methods and service life, and you need to ask clearly when ordering.

4) The shaft power and pressure of the motor are proportional, in order to prevent the long-term limit pressure from causing the shaft power to increase, the motor load is overweight, often used is the pressure relief valve, it is a relief valve, when the pressure of the high-pressure fan exceeds the pressure set by the pressure relief valve, the pressure relief valve will automatically open, the excess pressure is released, thus protecting the motor of the high-pressure fan.

Third, vacuum adsorption high pressure fan working principle:

Printing machinery vacuum adsorption high-pressure fan in the impeller rotation, due to centrifugal force, forming a series of spiral motion. The rotating motion of the gas between the impellers accelerates and sucks the gas outside the pump body from the suction port. After the gas enters the outer gas ring, it returns to the base of the blade by the action of pressure difference to form a strong airflow. This cycle makes the gas move in a spiral direction in the gas ring to achieve the purpose of pressurization. After the gas moves to the exhaust port, the pressure is greater than the system pressure, so the gas is quickly discharged. The function of high pressure fan suction and air supply is very wide.

Installation precautions:

    1. Installation location of transparent blower: it shall be installed in a place free from wind and rain;

    2. Ambient temperature: below 40℃;

    3. Relative humidity: below 80%;

    4. Air quality: If the air contains corrosive or flammable gases such as acids and alkalis, it should not be transported by high-pressure blowers to avoid danger;

    5. Dust protection: Avoid using it in places with a lot of dust, powder or fiber. If it is necessary to use it on such occasions, please install a filter and regularly clean the dust attached to the filter screen and high pressure blower.

    6. Ventilation and heat dissipation: Please choose to use in a well-ventilated place, not in a closed room or closed box;

    7. Storage space: for row maintenance or repair convenience, please avoid installation is too narrow place;

    8. Avoid vibration: Please install in a place without vibration; if vibration is unavoidable, anti-vibration measures must be installed to avoid damage to the high-pressure blower due to external vibration.

Operation and maintenance:

 1. After installation, the blower should be manually rotated before starting to check whether there is abnormal collision and friction, whether the rotation direction of the motor is correct, and whether the inlet and outlet valves are in a small flow state.

 2. When the fan is running, pay attention to whether there is abnormal sound inside the fan and motor, oil leakage, abnormal vibration or high bearing temperature rise, excessive motor current, loose feet and other abnormal phenomena, and eliminate them in time.

 3. The bearing grease should be replaced after 5000 hours of use of the new fan.

 4. Maintenance: Loosen the screws on the horizontal split surface, open the upper half of the casing and the upper covers of the bearing boxes on both sides, and take out the rotor to repair the rotor or casing. During maintenance, special attention should be paid to whether the impeller blades are broken, whether there are cracks, and whether the main shaft is bent. Before assembling and disassembling the upper casing, care must be taken to avoid damaging the rotor due to the swing of the upper casing during assembly and disassembly.

 5. When the fan leaves the factory, the user should cover the inlet and outlet of the fan during shutdown to prevent debris from falling into the fan cavity and causing accidents.
