Vacuum pump fishing industry

In recent years, large-scale marine engineering technology and equipment has attracted much attention. Some large-scale ocean-going fishing vessels have introduced more advanced fishing equipment, but all of them have been eliminated by foreign countries, and the introduction cost is very high. At present, domestic fish suction equipment usually consists of vacuum pump, suction barrel, electric control cabinet, reversing valve, suction hose and drainage pipe. The air generated by vacuum pump forms negative pressure in the suction barrel. Under the action of air suction, the catch enters the suction barrel through the suction pipe, and when the catch accumulates to a certain amount. Stop sucking fish and unload the catch by opening the valve at the bottom of the suction bucket. However, the existing electrical control cabinet uses relay control system composed of relays, contactors, buttons, limit switches and other electrical components. The relay control system has many contacts, complex wiring lines, easy burning and wear of contacts, resulting in poor contact and high failure rate; it is very difficult to increase or change functions. Difficult. The number of relay contacts is limited.

Vacuum pumps are not only used in fishing industry, but also Liquid ring vacuum pump are one of the most basic vacuum acquisition equipments in vacuum technology.  They can also be used in printing, photo-plate making, food packaging, vacuum suction, refrigeration equipment maintenance, instruments and instrumentation. Equipped with supporting equipment, etc.

When the Liquid ring vacuum pump is lower than the saturated vapor pressure at the pump temperature, it can be filled with gas and discharged out of the pump at any time to prevent solidification in the pump oil. In addition, when the closed pump mouth is running, the condensate or vapor phase of the condensable gas that has been mixed into the oil will dissolve in the oil, and will spill out from the pump chamber. At this time, if the task of the air-opening town, a certain amount of condensable material can also be extracted, thus playing a certain role in pollution and extending the use of pump oil. Period. Rotary vane vacuum pump oil is more expensive, the supply is unlimited, so reasonable use of gas town has great economic significance.

Liquid ring vacuum pump is widely used in industrial field. In the process of resin pouring, it is important not only that they reach the vacuum level of 0.1 millibar on a continuous basis, equivalent to 99.99% of the vacuum degree, but also that they can produce sufficiently high pumping speed in vacuum. After all, even if the synthetic nucleus is sealed with very precise aluminum foil, the leak may lead to the infiltration of a small amount of air, which then needs to be pumped again immediately. High vacuum performance ensures rapid, bubble-free and complete resin infusion. Rotary vane vacuum pump performance can be controlled by throttle valves, for example, if the need to prevent resin flow too fast into the die. This guarantees high quality products and means that the cost of repairs is no longer applicable. Their oil seal function means that the rotary vane vacuum pump is insensitive to the gases generated during drying. These are transported through a vacuum pump without being compressed. A resin trap is connected upstream of each vacuum pump to prevent resin from entering the vacuum pump.

The application of vacuum pump in fishing industry has greatly improved fishing efficiency. As mentioned above, it can be seen that the Liquid ring vacuum pump is widely used not only in fishing industry, but also in other fields, such as food packaging, drying, refrigeration, scientific research, medical, electronic, chemical, pharmaceutical and other professional units and colleges and universities. Laboratory, laboratory.
