Condensate pump seal

Release date:2015-06-15 16:10 Source:http://www.hotelsuninns.com Views:

The working condition of condensate pump for condensate pump is the possibility of the occurrence of cavitation erosion in condensate pump is extremely high vacuum transportation according to the saturation temperature..

In order to ensure the normal operation of the pump, at the installation of the condenser at the condensation level of at least 0 5---0.8m.

This will cause a water column in the inlet of the formation of a necessary pressure caused by the formation of the water column, to prevent condensation of water in the inlet vaporization of the pump, to ensure the normal water pump.

In addition, the suction side of the condensate pump is connected with the condenser and the condenser, so that the same pressure value can be maintained with the condenser and can prevent the air from the condensate pump.. The maintenance method of the packing of the condensate pump is as follows:

1, cleaning the stuffing box, and check the shaft surface whether there are scratches, burr, etc.. The packing box should be cleaned, the shaft surface should be smooth.

2, check the shaft, the rotor jitter should be within the range of the imbalance, so as to avoid excessive vibration, the filler unfavorable.

3, in the packing box and shaft coated with sealant or coating lubricant compatible with the media.

4 and on into coil packaging filler, when preferential root and the shaft neck size is the same stick, packing wound on the, and then with a knife cut, edge is best is beveled.

5, condensate pump filler to root filling, not a time to load a few. The method is to take a root filler, coated with lubricant, the hands of each side of the filler interface, along the axial, so that a spiral, then from the cut jacket into the journal. Do not pull along the radial, so as not to interface.

6, taking a box with packing with size material or with an axial hardness lower some of the metal sleeve to push the filler box deep, and the gland of the sleeve exerts a certain pressure, so be pre compression filler. The pre compression is 5%~10%, the maximum to 20%. The shaft rotates a circle, remove the sleeve.

7, with the same method, filling second, third. Note that when the number of filler is a root of 4 to 8, the filling should enable interface are mutually staggered; second packing staggered; 3 to 6 staggered to prevent leaking through interface. 8, after the last one filler loading, application of the gland, but the pressing force is too large. At the same time, the rotation axis of the hand, so that the assembly force tends to parabolic distribution. And then relax a little.

9, the condensate pump operation test, if you can not seal, and then compress some of the filler; if the fever is too large, it will relax some of the. So transferred to only a drop of leakage and fever when (the temperature of the filling site only 30 ~ 40 degrees higher than the ambient temperature), before it can officially put into use.
