First, the product overview

  HJ chemical process pump is a standard chemical process pump which is upgraded and innovated by our company on the basis of IH pump. The pump is a single-stage single-suction cantilever structure, the performance parameters in line with GB / T5662 (equivalent to IS02858) standards. In the design, the use of advanced hydraulic model, with higher efficiency than the IH pump increased by 5%, is energy-saving products. In structural design, the American ANSI standard is adopted, the shaft diameter is enlarged, the cantilever ratio is shortened, the shortcoming of frequent broken shaft of the IH pump is eliminated, the operation stability is improved, the maintenance cost and the operation cost are reduced. Company with reference to the United States API682 standards developed by the 171 series of mechanical seals have been successfully used in soda ash, chlor-alkali, salt, phosphorus chemical industry, metallurgy, environmental protection and other industries and easy to crystallize, multi-particle conditions. HJ pump now has more than 100 specifications, the basic coverage of 2.5MPa pressure, 200 ℃ temperature of all chemical process applications. It is one of the three most widely used chemical process pumps in China, which is the most widely used in China with CZ and ZA.

Second, compared with the IH pump, HJ pump structure has the following characteristics:

  1, shortened the impeller cantilever, bold shaft diameter;
  2, non-symmetrical cross-section of the volute, pump ring without mouth;
  3, the use of three imported bearings;
  4, equipped with advanced foreign double mechanical seal Or packing seal similar to the new seal;

Third, due to the above structure so that the pump has the following advantages:

  1, can transport high viscosity or solid medium, then pump efficiency is higher than the IH pump;
  2, asymmetric cross-section volute reduces fluid impact loss, shorten the size of the pump shell;
  3, increasing the shaft strength, reducing the Rotor's deflection, and thus stable operation, long sealing life;
  4, impeller nut and impeller made of one, to improve the pump inlet conditions, improve the pump anti-cavitation;
  5, advanced shaft seal form, so that the sealing effect is better , Reducing the pump leakage;
  6, can not dismantle the casing and impeller pump to adjust the gap, reducing the maintenance time and save maintenance costs.
