Liquid ring vacuum pump in beekeeping tools

The pulp production frame or base strip is covered with sterilized wet towel and sent to Qianjing sterilized room. Firstly, the heightening part of the platform base is cut off with a quick knife sterilized by alcohol. Then, the larvae are picked out with bamboo or stainless steel camera, and then the royal jelly is dug out with oil painting brush or small shovel made of ox horn and bamboo, and put into the plastic bottle. In order to improve the effect of extracting royal jelly and improve the sanitary conditions in the process of extracting royal jelly, we can use a pulp suction device to absorb royal jelly.

The aspirator is a kind of equipment which can absorb royal jelly from the platform base relying on the negative pressure produced by the suction device, also known as royal jelly aspirator. The utility model is composed of a suction device, a negative pressure bottle (which is omitted by some pulp absorbers), a slurry storage bottle, a spherical suction head, a pressure rubber tube and a glass tube. Depending on the air suction device, the air in the negative pressure bottle, slurry storage bottle, glass tube and rubber tube is pumped out from time to time to form a negative pressure system, so that the slurry suction head can absorb the royal jelly from the foundation into the slurry storage bottle.

The slurry suction device of the electric liquid ring vacuum pump adopts a small electric liquid ring vacuum pump (the pumping rate is. 5 L / s) as a pumping mechanism, it has high vacuum degree, high pumping rate and high working efficiency. However, it needs the place with electric power to use.

When new users choose in the market, it is inevitable that they will be at a loss and do not know which one to choose. Here are two key points for attention in equipment selection:

1、 Correct selection according to the amount of air extraction required by the system

(1. )When the type of vacuum pump or vacuum unit is selected, the correct model should be selected according to the amount of suction required by the system. Therefore, when the vacuum degree or gas pressure required by the equipment is not high, the single-stage pump can be selected first.

(2. ) If the requirements of vacuum degree or discharge pressure are high, single-stage pump can not meet the requirements, or the pump still has a large amount of gas in the case of higher vacuum, that is, the performance curve is required to be flat at higher vacuum degree, two-stage pump can be selected.

(3. ) If the vacuum degree is above – 710mmhg, roots water ring vacuum unit can be selected as the vacuum device.

2、 Vacuum degree of equipment

(1. )The vacuum degree of the selected vacuum pump is required to operate in the high energy range (that is, in the area of critical required vacuum degree or critical required exhaust pressure), so as to ensure the normal operation according to the required conditions and requirements.

(2. )It should be avoided to operate in the vicinity of large vacuum degree or large exhaust pressure range, because the operation efficiency is low and the work is very unstable in this area, which is easy to cause vibration and noise of vacuum pump.

(3.)For a higher vacuum pump, cavitation often occurs when it operates in this area. The obvious phenomenon of this phenomenon is the noise and vibration in the equipment.

(4. )Excessive cavitation will lead to the damage of pump body, impeller and other parts, which can not work normally.

Keep in mind the two major points for attention in the selection of liquid ring vacuum pump. It is very important to choose a good quality and suitable equipment for ourselves, so that our work process and work efficiency will be greatly improved.
