Domestic vacuum pump model preparation methods

On the domestic reciprocating pump, fixed-piece pump, rotary vane pump, slide valve pump, mechanical booster pump, steam jet pump and oil diffusion pump and other types of vacuum pump models that have been unified by JB1631-75. The entire model consists of six, the first three as the basic model, the latter three for the auxiliary model, the middle with horizontal lines separated. ① The first type of vacuum pump products that the pump series, with figures that single-stage pump can be omitted. ② The second type of vacuum pump product pump that the name, with Chinese phonetic alphabet said. Such as the reciprocating pump W, steam jet pump P, fixed-chip pump D, rotary vane pump X, slide valve pump H, oil diffusion pump K, booster pump for the z. ③ vacuum pump model third said Structural characteristics of the product pump. Use Chinese phonetic alphabet to express. ④ The fourth type of vacuum pump products that use the characteristics of the pump, mainly refers to the type of suction. When pumping gas is condensable, N is used. ⑤ vacuum pump model for the fifth product performance parameters, expressed in numbers. ⑥ vacuum pump model sixth product design sequence number. Starting from the second design, the Chinese phonetic alphabet printed in uppercase order. The above description is as follows: 2X-15 said two rotary vane vacuum pump model, pumping speed of 15L / s. XD-400 said single-stage rotary fixed vacuum pump model, pumping speed 400L / S. K- Diffusion vacuum pump model, import diameter of 80mm. [Vacuum pump model related reading] vacuum pump is a rotary varactor vacuum pump with a foreline must be used in cooperation with a wide range of pressure in the larger pumping speed to be removed Gas containing dust and water vapor insensitive widely used in metallurgy, chemicals, food, electronic coating and other industries. Mainly WLW series vertical oil-free vacuum pump model, W reciprocating vacuum pump model, 2X, 2XZ rotary vane vacuum pump model, ZJ, ZJH Roots vacuum pump (ZJH type for the patented vacuum pump products), 2SK, SK water Ring vacuum pump, 2BV, 2BA water ring vacuum pump, H, 2H slide valve vacuum pump, TLZ-type vacuum pump, SL Roots blower, JZJHX Roots rotary vane vacuum unit, JZJHS Roots water ring vacuum unit, JZJHWLW Type vertical oil-free vacuum unit, JZJP Roots water jet vacuum unit, JZJHBA Roots water ring vacuum unit, RPP-type water jet vacuum pump, JZJH2H Roots-spool valve vacuum unit and other vacuum pump models.
