Acid pump is also acid and alkali pump also known as the bulk pump, mainly for PCB plating, wastewater treatment, plastic and metal surface treatment industries. But what are the common failures and causes for this bulk pump? Acid and alkali pump According to the old technical engineers for many years after the sale of acid pump repair experience and found that the leakage of the shaft seal and pump in the work flow of this problem is very serious! Today it is a simple way to talk about it from several aspects. Symptom 1: Acid pump shaft seal leakage seal seal leakage caused by seal leakage Cause one: acid pump is not installed in the water start the motor test machine. Fault cause two: acid pump inlet pipe or outlet pipe is blocked, or impeller at the foreign body stuck (such as plastic bags, soft cloth and other sheets), the end of the valve and the outlet of the check valve will have stuck The phenomenon, especially for a place for use, do not often switch to use it easy to appear. Failure reason Three: Acid pump level controller failure, did not play a low level protection, may be many times are no problem, but once you can make the pump damage. Symptom 2-pump at work but insufficient flow Pump blockage Cause 1: acid pump at work but the pressure or flow is insufficient, in this case most of the impeller stuck foreign body or the pump block. Fault reason two: Acid pump power jump occurs when the boot, the main reason for checking the location of the relay, there is the motor junction box is damaged power line. Failure reasons Three: acid pump operation but no flow and pressure, two reasons: a motor reversal, two impeller damage. -------------------------------------------------- -------------------------------------------------- --------------------------- This article is published by Asia Fluid Network (), please indicate Asia Fluid Network
