No leakage pump main technique and should pay attention to the problem

1 no leakage pump main technology

1.1 Rotor axial force adjustment and balance

1.2 cooling and lubrication measures

According to the transmission medium, different working conditions, shielding pump cycle there are three main ways:

(1) is the cycle

(2) reverse cycle

(3) outside the loop

1.3 shielding sleeve, isolation sleeve and the gap

1.4 bearing and thrust plate

1.5 magnet rotor

1.6 status monitoring

2 no leakage pump should pay attention to the use of the problem

4. No leakage pump application prospects

Admittedly, a leak-free pump is more expensive to manufacture than a conventional pump, but its use and maintenance costs are much lower than those of a typical mechanical seal chemical pump. First of all, no leakage pump without mechanical seal and bearing box, the pump shaft is completely enclosed in the shield sleeve (isolation sleeve), the variable seal is a static seal, effectively solve the problem of leakage and lubrication; Second, the pump without a leak cancel the coupling, Harden the connection as a soft connection, effectively solve the vibration and noise problems; In addition, no leakage pump wearing parts significantly reduced (only the bearing or the mouth ring), the accident is also relatively reduced (only the inner and outer rotor); the last , No leakage pump to extend the life of the operation, maintenance frequency and time greatly reduced, and significantly reduce the labor intensity overhaul. According to the statistics of ABS device from 2000 to 2001, the damage rate of conventional pump is 6 to 8 times that of non-leak pump, and the cost of replacement of consumable parts by mechanical seal chemical pump is 3 to 5 times of that of similar pump without leakage. According to the cumulative total cost calculation, roughly 4 ~ 5 years the number of both the same. The above is only from the cost point of view, and mechanical seal chemical pump leakage of materials tend to be expensive, caused by environmental pollution, safety accidents and other issues more.

Therefore, although a one-time investment without leakage pump larger, but no leakage of pollution, saving materials, maintenance and management of low cost, high overall economic efficiency, good social benefits. With economic development, social progress, state requirements for enterprises in technology, environmental protection and other fields are getting higher and higher, and vigorously promote the technology of leak-free pump technology has a good prospect.
