What water ring vacuum pump application advantages -

water ring vacuum pump application advantages

1, water ring vacuum pump working pressure should satisfy the limit of vacuum equipment vacuum and work pressure requirements. For example, vacuum coating requirements of vacuum degree is 110 - 5 MMHG, selected water ring vacuum pump vacuum degree should be at least 510 - 6mmHg。 Usually, the selected pump vacuum degree higher than vacuum degree of vacuum equipment to half an order of magnitude.

2, correct selection of water ring vacuum water pump working point. Each pump has a certain job stress scale. For example, scattered pump is 10 - 3 ~ 10 - 7mmHg。 In such a wide range of pressure, pump speed change with pressure. About 510 - 6mmHg。 As a result, the working point of the pump should be within the scope of the choice, and should not be long in 10 - Work under the 8 MMHG. Another example is the titanium can lift pump in 10 - 2 MMHG under the pressure of work, but the work pressure should be less than 110 5mmHg。

3, water ring vacuum pump should be able to work in the pressure to remove all gas produced during vacuum equipment technology.

4, water ring vacuum pump has the right combination. Because the water ring vacuum pump with selective pumping function, so sometimes you can't use the pump to meet the pumping requirements. Need to pump more together to complement each other, in order to meet the pumping requirements. Titanium, for example, can improve the pumping speed of pump for hydrogen, but it can't pump helium, and three pole sputtering ion pump ( Or the asymmetric between the cathode sputtering ion pump) For argon gas pump speed. Combined with vacuum equipment to obtain a better vacuum. In addition, some of the water ring vacuum pump can not run under atmospheric pressure, vacuum need. Some water ring vacuum pump outlet pressure below atmospheric pressure, and the need to pump before, so you need to combine.

5, for vacuum equipment caused by oil pollution. If serious equipment requirements without oil, should choose a variety of oil pump, such as water ring pump, molecular sieve adsorption pump, sputter ion pump, cryogenic pump, etc. If not strict, you can select the pumps and add some oil pollution prevention methods, such as adding cold trap, baffle, the oil well, etc. , and also to be able to achieve the requirement of the vacuum cleaner.

6, know to pumping gas composition. The gas does not contain condensable vapor, whether whether particles of dust and corrosive. Choose the water ring vacuum pump, you need to know the gas composition, and to choose the appropriate pump for pumping gas. If the gas contained in the steam, particles and corrosive gas, should consider to install auxiliary equipment in the inlet pipe of pump, such as condenser and dust collector.

7, water ring vacuum pump oil vapor have any impact on the environment? If you don't allow pollution environment, you can choose oil-free water ring vacuum pump, and are likely to be oil vapor emission to the outdoor.

8, during the running of water ring vacuum pump vibration does not affect the technical process and the environment. If you don't allow technical process, should choose no oscillation of pump, and should adopt the method of preventing oscillation.

9, the price of water ring vacuum pumps, operation and maintenance costs.

winter cover pump water pump processes have been widely used to produce pool cover drain pump such as winter cover pump, pool cover drain pump, and winter cover pump etc.
J&T INDUSTRY CO.,LTD.’s mission is to use our extensive water pump experience to deliver tangible business results enabling our clients in industry and government to profit from the advanced use of technology. We strive to build long-term client relationships based on mutual trust and respect.
J&T INDUSTRY CO.,LTD. agreed, noting that successful social marketing will become an even more important component of overall marketing strategies, and that marketers will have to think longer, harder and more creatively if they want to be able to fulfill the newly created potential of pool cover drain pump.
J&T INDUSTRY CO.,LTD., which contributes itself on water pump for creating more useful application.
J&T INDUSTRY CO.,LTD.’s model also predicts (i) a positive effect of management on firm performance; (ii) a positive relationship between product market competition and average management quality (part of which stems from the larger covariance between management with firm size as competition strengthens); and (iii) a rise (fall) in the level (dispersion) of management with firm age.
