Selection of Axial Flow Pump with Bearing
Axial flow pump has the characteristics of low flow and low flow. It is widely used in industrial and agricultural production. Yixi 870 axial pump in the salt industry to use more from the use of some manufacturers look at the pump cycle is generally shorter, a large part of the reason is the bearing failure. Although there are many new domestic axial pump, but the use of performance to meet the salt production and can replace the color 870 axial pump see little. Color 870 axial flow pump in the use of performance, although there are many shortcomings. Over the past two years the salt factory gradually replaced. ACP-I-type circulating pump, but the actual situation of the plant, in recent years is not eliminated. How to tap the existing equipment potential, improve equipment utilization, reduce equipment maintenance costs, which is the common aspiration of each manufacturer. This article will be j2 "870 axial pump with bearings to be discussed in order to extend the axial flow pump cycle to make a little effort. Second, the actual use of Hubei Province chemical plant salt factory color 870 axial pump in use, the operating cycle has been lower, mainly due to mechanical seal failure and bearing damage caused. Only according to the January-June 1990 overhaul statistics. 2/5 times the number of times because the bearing damage and maintenance. I believe that the reasons for bearing damage are as follows: 1. Support type j2 "870 pump design of the original support type is the front assembly of two 2230 bearings. Back-end pairs of two 7530 bearings.
