Small vacuum pump out _

small vacuum pump is a variety of small pump suction vacuum unit work, is widely used in refrigeration equipment, medical equipment, printing machinery, vacuum packaging, vacuum forming, physical and chemical experiments and small equipment are in need of repair vacuum environment. And involved in scientific research, gas sampling, instruments and apparatus, chemical analysis, medical and health care, medicine, biological engineering, automatic control, environmental protection, water treatment, such as gas/water quality analysis instruments, PM2. 5 detection, 3 d printers, medical equipment, health and beauty equipment, automation equipment, an object, adsorption, military automation equipment and so on many fields. Vacuum pump of the company's technical team of engineers and a small vacuum pump in detail the application of knowledge sharing. Hope to help everyone.

in many fields of many machinery manufacturing equipment, small pump belongs to one of the most important part, its importance is self-evident.

small oil-free vacuum pump and the big one of the most obvious difference is the difference in size, but the focus of the real need to understand the advantages and disadvantages of these below:

large vacuum pump features: big power, limiting vacuum ( Very small absolute pressure) ( Absolute pressure, higher limit vacuum generation) , some can even do it ten times of the negative, very close to the theory of vacuum. Pumping rate is high, usually 'L/S ( L/s) 'for the unit.

the disadvantage of large vacuum pump: although high vacuum, low vacuum, but in a lot of waste, such as laboratory, to pumping gas sampling needs only a small amount of gas, gas analysis, gas cycle, vacuum, gas transmission, booster, indirect water and drainage, large oil-free vacuum pump can not meet. No pollution, do not meet the demand of the medium of analysis of interference, but the price is expensive, bulky, heavy, high noise, high energy consumption, not easy to move need regular maintenance. Some large vacuum pump oil or lubricating oil must be used in the oil mist, are generated as pollution and so on. 。 。 。 。 。 As the working medium.

small vacuum water pump: the advantages of low vacuum, Under vacuum) , compression, low noise, low power consumption, easy operation, easy to carry, free maintenance, 24 hours of continuous operation, also can let water vapor rich medium. The most important thing is, there is dry, no oil, no vacuum pump oil or grease, no pollution, no interference with the media analysis, etc. , the price is much cheaper, and so on.

how to buy a small vacuum pump?

small vacuum pump suction gas not only to achieve, and the effect such as realized the supercharger, it is necessary when the choose and buy should pay attention to the following three questions.

1) Described in the medium temperature

dielectric gas temperature of the vacuum pump, normal or high temperature.

2) Electromagnetic interference

small precision pump control circuit, anti-jamming circuit, depending on the ability to choose low electromagnetic interference of small pump.

3) Reliability problems

in the capacity of small vacuum pump, under continuous operation, and trouble-free continuous running time is greater than the large vacuum pump, the working life of the optional.

4) Load start

adjustable pump or the pressure container of small vacuum pump, to maintain the vacuum state, or when the vacuum pressure is lower than the value of the container, the choice of pump power, the shutdown is higher than set value.

small vacuum pump failure and processing method 1, pump shaft bearing wear a

vacuum pump driving part wear is a common problem, including the position of bearing, bearing, bearing cavity, slotting and thread parts, such as the traditional way to repair and painting brush, suitable polymer materials to repair, remove, without processing. Neither welding thermal stress, unlimited repair thickness, and the product has metal materials do not have properties, the device can absorb shock vibration, again in order to prevent the possible wear and tear, and greatly prolong the service life of the equipment parts to save a large amount of downtime, maximize the economic value.

2, shell burst break

by vacuum casting, machining defects, such as internal stress often lead to overload component exhibits cracking or breakage. The traditional way is to use a welding repair, or to prevent 'cold welding' technology, thermal stress and deformation, and data compression and adhesiveness, good corrosion resistance ability, can use all sorts of equipment meet the component request, in order to effectively guarantee the lowest cost consumption. Safe, convenient and reliable.

3, corrosion

corrosion can be divided into two major categories of a comprehensive corrosion and corrosion, than in the external vacuum all the plot before, this is only a partial onset seizures, using vacuum pump preservative purposes outside the small vacuum pump to form part of the organic polymer composite coating, with heavy structure, low cost, safety performance is good, the maintenance effect is good wait for a characteristic, compared with good chemical resistance and mechanical properties and excellent adhesiveness, with past pressure vessel welding repair.
