Reciprocating vacuum pump failure analysis and solution

Reciprocating vacuum pump is a kind of vacuum pump can be used for vacuum concentration, vacuum distillation, vacuum filtration, vacuum concrete vacuum, vacuum drying and other industries have significant work ability, reciprocating vacuum pumps not only improve the rapid development of these industries, but also improved Own ability. However, in actual use, reciprocating vacuum pump occasionally there are some cases, these conditions easily affect the reciprocating vacuum pump usage, users need to deal with the reciprocating vacuum pump failure in a timely manner. Reciprocating vacuum pump failure analysis and solutions 1, start difficult Failure Analysis: power supply failure, foreign matter into the pump, the impeller stuck, the packing pressed too tight, scale or rust, too much working fluid; Solution: check whether the power, or Power phase, wash with water, or open the pump inspection, loosen the gland bolts, start the pump, slowly tighten the gland bolts to a little water outflow soaked with 10% oxalic acid for 30 to 60 minutes to adjust the working fluid, Height to the pump axis; 2, the motor overload Fault Analysis: Winding short circuit, the working fluid flow is too large, the exhaust pressure is too high, too much liquid content in the inhalation gas, exhaust valve damage; Solution: Check the motor windings , Adjust the working fluid inlet valve to reduce the flow of working fluid to reduce the exhaust pressure to the specified range, replace the exhaust valve; 3, the vacuum is low Fault analysis: the working fluid temperature is too high, the system slightly leaked, the pump gap is too large , The vacuum gauge is not allowed, the pump selection is small, the local atmospheric pressure is low; solution: lower the working fluid temperature, suppress leak detection and repair, replacement packing or mechanical seal, and more Vacuum table, re-selection, replacement of large pumps, replacement of exhaust valve; Through the above analysis of the reciprocating vacuum pump failure, we can probably know the reciprocating vacuum pump failure of what kind of situation, but in actual work, reciprocating vacuum pump failure is impossible Sturdy, then you need to use the wisdom of users to solve the problem. Believe in the support and help from all walks of life, reciprocating vacuum pump failure will be able to get a good solution. This article is copyrighted industry interconnect (Xiamen) Co., Ltd.
