Vacuum Pump Repair

Problems with vacuum pumps can severely hurt the production of a facility.  When the pump stops working, production halts and processes stop.  This downtime is expensive – we understand that, and will work to get vacuum pumps fixed as quickly as possible.

Vacuum pumps are one of the widely used equipment in process plants. It is very important to correctly size and select the vacuum pump as it is also to lay down the right specification. The vacuum pump means the transport, storage, installation, commissioning, and influence on operating conditions, maintenance, troubleshooting and overhaul of the vacuum pump. The vacuum pump is intended for industrial use. It shall be handled only by qualified personnel.

The selection of a proper vacuum pumping system is highly application dependent and is complicated by the wide variety of operational, process and equipment issues. In many instances, the incinerator and pumping system are pre-existing and we have little choice other than to operate at a predetermined vacuum level.

Typical vacuum applications include industrial, food and packaging, coatings, analytical and medical technology, solar, semiconductor technology and research & development. Each system must meet a specific set of requirements that are imposed by the process and production requirements. These requirements ultimately determine the size and type of pumps needed for the successful operation of the system.

Operation for vacuum pump repair service

Several factors govern and influence the performance of a vacuum system. It is important to periodically inspect the vacuum system and all its accessories including the upstream and downstream piping and equipment for leakages as it plays a major role in the performance of a vacuum system.

Some of the common problems faced in vacuum pump repair service could be on account of the following major factors:

  • Process conditions and variations
  • Variation in utility specs
  • Equipment malfunction

The suction load, temperature, leakage rate and other process parameters including the composition of suction gas are crucial for proper functioning of a vacuum system. These standards can also be applied for testing the performance of the vacuum system. Once the external step is to evaluate and solve the problems associated with the vacuum unit.

Some of the most commonly observed problems in different kinds of vacuum pump repair along with suitable troubleshooting guidelines are discussed below.

Leakage

If the seal water is leaking from the pump, a cautious observation of the particular location of the leak and the quantity of the leakage should be carried out. Most areas of leakage are:

  • Gland packing area – It can be resolved by tightening the packing and if leak still persists, replace the packing.
  • Leakage at the gasket – Torque the body bolts evenly, if a leak does not stop, and then replace the body gasket.
  • Leakage at the plugs – Tighten the plugs. If leak still persists, check for corrosion on plug threads and body threads. Replace plug if corrosion is severe.
  • Leakage through castings – Causes can be erosion, corrosion or insertion of a hard object into the pump.

Noisy Pump Operation

Noisy pump operation could be due to:

  • Foreign object trapped into the pump – This is a very serious case and is usually accompanied by erratic noise and vibration.
  • Pump severely overloaded with water – Causes groaning and hydraulic noise.
  • Cavitations – Sounds like marbles in the pump.
  • Bearing noise – Possibility of bearing failure.
  • Lots of carryover to the pump – This is accompanied by high horsepower.

Pumping Speed is too Low

  • Dirt – trap in the intake port is clogged – Clean the dirt-trap. Make sure that dust filter is installed in the intake line.
  • Exhaust filter is clogged – Install new filter elements
  • Connecting lines are too narrow or too long – Use adequately wide and short connecting lines
  • Anti-suck back valve is hard to open – Check spring for free length.

Knocking or Locked up  

  • Unit out of time due to worn bearings or gears – Replace worn parts.
  • Rotors touching each other due to excessive temperature – Reduce temperatures by lowering differential pressure.
