Diagnosis of Accelerator Pump Failure in Oil Dispensers
Oil dispensers are generally used in the medical, mechanical, and electrical industries to dispense precise amounts of oil into components and machines. Most of these dispensers are powered by an accelerator pump, which increases the rate and consistency of oil captured in the dispenser. The pump also helps to reduce waste and improve the efficiency of the whole system.
Unfortunately, the accelerator pump can also be prone to failure. This article will explain some of the common signs and symptoms of an accelerator pump failure, and provide guidance on how to diagnose and repair the pump.
Symptoms of Accelerator Pump Failure
The most common symptom of an accelerator pump failure is a decrease in the rate of oil dispensed from the dispenser. This decrease in rate can be noticed most easily when the normal rate of oil dispensed from the dispenser is compared to the rate of oil dispensed when the pump is not in use. Additionally, the amount of oil collected in the dispenser can become inconsistent, as the pump is no longer providing enough force to propel the oil through the system.
In addition to the decrease in rate, an increase in noise can also often be heard when the pump is faulty. The noise is usually a higher pitched whine, which is caused by the increase in air pressure created by the faulty pump.
Diagnosis of Accelerator Pump Failure
The first step in diagnosing a faulty accelerative pump is to check all of the electrical contacts within the pump. These will usually be located near the inlet or outlet of the pump, and can easily be tested using a multimeter. If the contacts are in poor condition, or if there is a visible loss of conductivity at any of the connections, then the pump may need to be replaced.
The next step is to check the intake and exhaust valves of the pump for any signs of obstruction or leakage. These valves can be accessed by removing the pump from the dispenser. If either of the valves appears to be blocked or leaking, then the pump may need to be replaced.
Finally, the internal pressure of the pump should also be checked. This is done by opening up the pump and measuring the pressure within the device itself. If the pressure is found to be lower than the manufacturer’s specified specification, then the pump may need to be replaced.
Repair of Accelerator Pump Failure
If the pump is found to be faulty, then the first step in repairing the pump is to replace any faulty electrical contacts. This process should be completed by a qualified electrician or engineer.
Next, the intake and exhaust valves of the dispenser should be checked and replaced if necessary. Ideally, this should be completed by an experienced mechanic or engineer.
Finally, the pump should be checked for any signs of damage or wear, and should be replaced if necessary. It is important to ensure that the pump is replaced with an identical model, so that the system is working at optimal efficiency.
Conclusion
In conclusion, accelerator pump failure can have a major impact on the efficiency and effectiveness of an oil dispenser. The key symptoms to look out for are a decrease in the rate and consistency of oil dispensed, as well as an increase in noise when the pump is in use. To diagnose this fault, it is important to check all electrical contacts, valves, and the internal pressure of the pump. If the pump is found to be faulty, then it should be replaced with an identical model.
