Oil seal vacuum pump working principle and structure

[Oil News] Oil-sealed vacuum pump with the gradual expansion of the application, it is how to work more and more by everyone's attention. For the oil-sealed vacuum pump, its important feature is to obtain a higher degree of vacuum, and its working principle is sealed between the various parts and exhaust valve parts, resulting in a higher degree of vacuum. Oil-sealed vacuum pump working principle and structure chart Nowadays extensive use of mechanical vacuum pump, the movement between the parts with high accuracy. It is also difficult to prevent gas from "breaking" backflow from the low vacuum end to the inlet end when the pump reaches the ultimate vacuum. Due to the unavoidable unwanted space in the design, manufacture and assembly of the pump, this also reduces the ultimate vacuum of the pump. Oil-sealed vacuum pump is the use of oil will be moving parts and exhaust valve seal between the parts; at the same time harmful space filling, making high-pressure gas anti "breakthrough" much less chance of sealing performance is much better, so that the pump Can achieve a higher degree of vacuum. The use of oil to keep moving parts of the seal, depending on the pump chamber volume change to achieve the mechanical vacuum pump suction pump oil seal. At the same time the use of oil to keep moving parts of the seal, depending on changes in the volume of the pump to achieve the mechanical vacuum pump suction pump oil seal. Their working principle is to make the pump chamber volume increases and decreases mechanically and exhaust. When the working chamber volume in the pump chamber becomes minimal, it communicates with the inlet pipe of the pump, whereupon the gas enters the pump suction chamber until the suction chamber volume is maximized and re- separated from the intake port. When the volume decreases, the gas is compressed until the pressure of the gas is greater than one atmosphere and the vent valve is opened to vent the gas. At present, the oil-sealed vacuum pump is one of the most widely used vacuum access technologies in China. It can be used not only as an exhaust pump for low-vacuum equipment alone, but also as a front-stage vacuum pump for high-vacuum exhaust. Mostly used in the vacuum industry, oil-sealed mechanical vacuum pumps are mostly medium and small rotary vane pumps and medium and large-sized slide valve pumps. Therefore, it has played an increasingly important role in many sectors, such as electric vacuum, electronics, light chemicals, steel, non-ferrous smelting and other industrial sectors. As oil-sealed vacuum pumps are equipped with air-ballast devices, so you can also remove the damp gas. However, it is not suitable for the treatment of gas with high oxygen content, explosiveness, corrosiveness to ferrous metals, chemical attack on pump seal oil and dust containing particles. At present, many domestic research institutes and manufacturers are designing and producing a series of oil-sealed vacuum pumps that draw water vapor and corrosion-resistant. With the development and application of new technologies and new materials, all kinds of oil-sealed vacuum pumps with better adaptability to meet various industrial needs will surely be produced.

PH-B-L6

Phlizon`s COB series Grow Light emits all the wavelengths of light which can be fully absorbed by the plants to create.

Best full Specturm designed to perfectly match large areas of indooor plants, especially for Medical Plant.

COB + Dual-chip,most efficient spectrum,high PPFD.Two cooling fans with double ball(import from Japan) and big aluminum heat sink to protect the grow lights from high temperature,good cooling,long lifespan.Photosynthesis and promote healthy growth budding and flowering.

1000w/2000w /3000w COB LED Grow Light, it will give you more options when your plants need different strength of illumination.

Grow Lights are a great choice for growers who are dealing with hot HPS lights and want to change to something that's going to run cooler. Although LED Grow Lights do produce heat,the smaller models might not bring up the temperature of your grow space.Even the more powerful models of LED grow lights that produce a lot of heat still have built-in cooling systems to help prevent the heat from beaming directly down onto your plants.

WHAT MAKE UP AN EXCELLENT LED GROW LIGHT ?

1.PPFD Value : PPFD is Photosynthetic Photon Flux Density. When you choose a plant light, you should compare the PPFD values of different plant lights. The larger the value, the better the growth of the plant.

2.Actual Power: Because the actual power of the plant light always varies with different conditions, all Amazon sellers use the rated power to describe the power of the product because the rated power is constant. When you pick a LED grow light, the rated power of the plant light is a reference, and more importantly is the actual power.

3.Core Coverage: In addition to the above two, when you choose a plant light, you also need to compare the cover area of different plant lights, of course, the size of the core coverage area. In general, in germination stage, you can hang the plant light higher and the cover area is larger. In flowering stage you can hang the plant light lower and the cover area is smaller because the plant needs more light at this stage. You have to compare different coverage areas to choose the plant light that suits you.
