Water ring vacuum pump failure should do -

a six major considerations, water ring vacuum pumps

medium and its temperature should be in the range of allowable pump material. Engineering plastics for 60, the working temperature of water ring vacuum pumps and metal water ring vacuum water pump working temperature is 100, conveying suction pressure is not greater than zero. 2 million mpa, the maximum working pressure of 1. 6 million mpa, the density is not more than 1600 kilograms/stere, viscosity is not more than 3010 - 6 square meters/seconds.

( 2) If the transport medium containing solid particles, should increase a filter in the pump inlet; If they contain ferromagnetic particles, should add a magnetic filter.

( 3) Water ring vacuum pump when using the environment temperature should be lower than 40, the motor temperature rise of less than 75.

( 4) Magnetic pump normal operation after 1000 hours, should remove the bearing and end ring, check the wear, replace the wearing parts are not suitable for reuse.

( 5) For easy to precipitate crystallization medium, should be timely cleaning after use, discharge pump inside the accumulation of liquid.

due to the magnetic pump bearing cooling and lubrication depends on the transmission medium, banned the idling, avoid the idle work to restart after the power outage.

traditional welding machine and processing method is easy to cause material damage, deformation or fracture cause, has great limitations. Brush plating and spraying reprocessing method often need to outsourcing, it not only repair cycle is long, the cost is high, and as the repair material is the metal material, can not fundamentally solve the wear and tear.

polymer composite patching material has strong adhesion, excellent compressive strength, abrasion resistance and corrosion resistance. The polymer composite restorative materials can wear is relatively small in driving part of the scene without disassembly repair, avoiding the mechanical processing, will not reduce the heating effect of the welding thermal stress, thickness of repair is not restricted; At the same time, the wear resistance of the product and metal materials do not have the concession to ensure the repair parts contact with 100%, reduce the impact of vibration equipment, avoid the possibility of wear and tear, greatly extend the service life of the parts, equipment for enterprises to save a large amount of downtime, created a huge economic value.

2, water ring vacuum water pump bearing temperature rise process and matters needing attention

( 1) Causes of high temperature lubricating oil.

( 2) Water enter the bearing box, lubricating oil emulsification metamorphism.

( 3) There are impurities in bearing box.

( 4) overload.

( 5) Balance disc multistage pump clearance is too large.

water ring vacuum pump bearing pump maintenance methods:

( 1) Replace the lubrication oil in the bearing chamber.

( 2) Clean the bearing box several times.

( 3) According to the technical index decrease the workload.

( 4) Adjust the multistage water ring vacuum pump balance board clearance, reduce leakage.
