Disassembling process and common problems - mechanical vacuum pump

mechanical vacuum pump solution known as maintenance, all of the part to fold solution countermeasures to fault detection of some of the vacuum pump, the vacuum value is still low, there is still leaking condition; Or some pump is one of the following conditions: such as pump produced 'stuck' condition, oil well dirty and had married within the water pump scale, rust is not modest oil or used to make the mechanical vacuum water pump through a joke on the internal parts ( Methyl silicone oil into the mechanical vacuum pump, it will cause this kind of situation) , rotary vane has a great beat, pump cavity fall into the dirt, Metal materials chip, chip sandwich glass, copper scrap, etc. ) Friction scratches pump cavity, burning temperature is very severe, More than 70 ℃) Wait, all the mechanical vacuum pump must be fully develop the maintenance disassembly.

disassembling processes of mechanical vacuum pump and common problems of the following:

1, the disconnect switch power supply, unplug the power cord plug. The pump such as on the system software, should be removed from the machine.

2, screw bolts in opening to the outside world oil and adding oil, hard disk moving belt wheel, make the oil more than pump cavity all released. Good oil should be collected, usually in the mechanical vacuum pump oil blank issued a iron disk or hard disk (such as Generally referred to as the square plate) Collect, facilitate in the future water vapor distillation acquisition and from environmental pollution.

3, down to belt, removing the pulley, key, loose negatives, depending on the motor quality levels ( Such as the noise of the hot, dirty, polishing, vibration is very big, etc. ) Should be maintenance or send welders wash oil maintenance.

4, first low vacuum pump down the end cover ( Back-end development cover plate, that is, put an end to one end of the pump wheel) Application, based on the different screw when disassembling different special tools. For general hexagonal screw can stay wrench, socket head cap screw with hex wrench, socket wrench shall be used when necessary, so it is not easy to damage the screw. After began to cover screw, light qi side cover plate. End cover plate such as closed too tight, should be gradually managed to stand aside. Can, for example, sharp knife in the pump chamber and the side cover plate commissure file a small groove, then use a screwdriver ( A screwdriver) In small slot place he screwdriver door, also can use the hammer knock a screwdriver to withdraw from the cover plate, not heavy hammer percussion.

5, with rubber sealing ring sealing is to take out the rubber sealing ring, withdrawn from the locating pin.

6, remove the rotor and rotary vane. Generally in low rotor end and set up two tapping away the silk Bi away with ball screw screw in the Bi is easily pulled low rotor. But be careful when pull the rotor must be forcibly knead a rotary vane, because rotary vane play Huang Li is large, a large since very easily changed hands, fell on the ground or lump, rotary vane water chestnut and surface cause crashed subscription fee for no apparent reason.

7, paragraph 4, 5, 6, much the same way that the mounting high vacuum pump terminal, take out the high rotor and rotary vane. At this time, as long as with the hand hold rotary vane and the rotor shaft can be removed.

8, before beginning ability dismantle pump, pump should be clear in advance to fold the solution of the structure characteristics and the probably belong to which components structure form. For example, for these itself belongs to component artifacts, as some of the rotary vane pump rotor, etc. , are not tear open outfit, can adjust its surface moderate adjustment; If the composition of the rotor to fall into the laminated glass crumbs and metal material within the dirty things hurt lumen or its rotary vane slot has damage too much, need to repair in spare parts, the demountable type, but be careful to remember their way of assembly line.

9, every tear open come down to a component, must examine the precision and smoothness and destroyed. The water chestnut on both sides of the vane and the rotor will need to pay attention to check the presence of damage, and make record. In view of the business process is not yet very well repairing pump, more should be gradually remember the tableland of members or spare parts assembly parts, keep records, prevent to install couldn't remember wrong. In addition, the removed parts can not be heaps, inclination, ke is injured, lost. Put it in a square in the hard disk is best, can also be in the box and clean and tidy, with linen cloth cover.
