Pump industry suppliers to tell you: the desulfurization pump slurry cycle analysis of the sealing technology

desulfurization pump slurry circulating pump sealing technology analysis

desulfurization slurry circulating pump seal has a simple structure, long service life, good sealing, easy installation, economic price, and many other advantages, the desulfurization slurry circulating water pump sealing technology idea is perfect, but, after all, is a design, is a kind of ideal condition, how is the effect still is to be tested by practice. Desulfurization slurry circulating pump seal cause of abnormal operation is mainly caused by the following aspects:

a, desulphurization pump slurry circulating pump problems in the design of the structure, main show is:

a spherical steel rubber pusher insufficient rigidity, conveying liquid at above 65 ℃ will deformation, failure, good solve this problem, increase strength and temperature resistance of rubber.

two elastic adjustment system adjustment of dynamic and static ring room slants big, top scale, the operator is difficult to grasp. Caused by improper desulfurization slurry circulating pump to adjust, dynamic and static ring wear craze, the solution is to reduce the adjustment allowance, change the way of adjustment, it quantifies the regulating mode, operational.

three desulfurization during slurry circulating pump pump, water pump pressure field of import and export impact on seal, the sealing parts of the cavity pressure changes fluctuation is too big, caused the desulfurization slurry circulating pump seal operation is not stable, the solution: improved design, blocking the effect of import and export pressure field, the improved to overcome the shortcomings.

second, the problem of seal assembly method.

mainly embodied in the dynamic and static ring the tightness of the force that press a tight grasp, if loose will discharge, if the tight of dynamic and static ring wear, the difficulty is the main cause of the problem in the process of manufacture. The desulfurization slurry circulating pump manufacturer after more than two years of exploration, to solve.

three is the damage caused by the use of improper conditions.

basically has the following several ways: one is the high post using suction, suction 1 m high; Medium and desulfurization slurry circulating pump seal material does not match the positions, such as the positions of ammonia desulphurization, should choose ammonia resistant rubber ring, otherwise life will not long.
