Dry vacuum pump than rotary vane vacuum pump, reciprocating pump is strong where _

there are different kinds of vacuum pumps, rotary vane vacuum pumps and reciprocating pump, for example, they are both vacuum water pump. In addition, there is also a dry vacuum water pump has a high market share. People more interested in the performance comparison between them, so here who compare them to understand better.

1。 Rotary vane pump and the comparison of dry vacuum pump common problem: rotary vane water pump common problem: there is a medium vacuum pump, easy to produce in the process of work flow. Work during the extraction of condensable gas for fluids, which can lead to lower vacuum degree of vacuum pump. Vacuum oil needs regular replacement, maintenance cost is very high.

the dry vacuum pump common problem: no medium in the process of vacuum pump, vacuum clean, no reflow, concentrated water drainage and focusing on vacuum pressure can maintain a constant and free of maintenance costs.

2。 Reciprocating pump compared with dry vacuum pump common problem: reciprocating pump ( W pumps, piston pump) Common problem: no medium vacuum pump, the structure belongs to the relative sliding of the piston and cylinder form a vacuum environment, when encountered crystallization medium chemical industry, it is easy to damage the piston and cylinder, results in the stagnation of production. When pumping gas contains large amounts of fluid, this method is not applicable.

dry vacuum pump common problem: no medium vacuum pump, frictionless structure and working principle of the variable capacity compression type. When the crystallization medium exist in the chemical and electronic industries, are poised to remove the crystallization medium without damage to the pump body.

when thrown the so-called goods, you can see the dry vacuum pump is superior to other two pumps. The use of dry pump can greatly reduce maintenance difficulty, save the maintenance cost; More durable, long-term free maintenance, no media operation can effectively improve the production quality of the product.
