Water ring pump of the main advantages and disadvantages

the advantages of water ring pump, water ring pump faults

a, what is water ring pump water ring pump is a mainly used for coarse vacuum in vacuum water pump, such as self-priming water pump inlet piping extracting gas to achieve the effect of water diversion, water ring type vacuum pump the swept volume of 1. 5 - 250 m3 / min, the limit pressure of 2 & times; l02 ~ 1报; 104Pa。 Main models have sz, SZB, SK and 2 be1 type. SK series water ring pump performance curve as shown in figure 2 5. The main technical parameters of water ring vacuum pump product introduction page visible reference. Second, the advantages of water ring pump:

1) water ring pump overall structure is simpler, manufacturing process requirement is not high, do not need air suction valve and exhaust valve;

(2) of the gas near isothermal compression, compression water pump is no friction between the metal contact surface, not easy burning explosion accident;

3. Suitable for pumping gas containing steam, liquid or solid particles;

(4) the pump cavity between the rotating and fixed parts from liquid seal, no lubrication.

3, the shortcomings of water ring pump:

1) water ring pump efficiency is lower, generally 30% & ndash; And the energy consumption is larger;

2. Its noise than rotary vane vacuum pumps or oil-free vacuum pump, also more than in 95 db above, some as high as 105 db, causing serious noise pollution.
