1、 Precautions during disassembly.

Be careful when disassembling the mechanical seal. It is prohibited to use a hammer and a flat shovel to avoid damaging the seal. A pair of steel wire hooks can be made, and the sealing device can be pulled out to extend the profit and loss direction to the gap between the transmission seats. If scaling cannot be removed, it should be cleaned thoroughly before disassembly.

If both ends of the pump are sealed with mechanical seals, mutual care should be taken during installation and disassembly to avoid missing each other.

3. For mechanical seals that have been in operation, if the gland is loose and the seal is moved, the dynamic ring components need to be replaced, and continuous use from the head is not allowed. Because in this situation, the working track of the friction copy will change, and the sealing of the touch surface is easily damaged.

2、 Device precautions.

1. Be careful to avoid device errors in the device.

a. After aligning the coupling, cover the upper part with evenly supported bolts to avoid deviation of the cover end face. Check each point with a feeler gauge, and the error should not exceed 0.05mm.

b. The mechanical processing factory checks the cooperation clearance (i.e. concentricity) between the gland and the outer diameter of the shaft or sleeve, and the surrounding area is uniform. Use a feeler gauge to check that the tolerance of each point is not more than 0.01mm.

2. The tightening of the spring should be carried out according to regulations. It is not allowed to have scenes that are too large or too small. The request error is 2.00mm. The meeting increased the specific pressure on the end face and worn the end face at another speed. If it is too small, the pressure is insufficient and cannot be sealed.

3. After moving the ring device, the beard can move sensitively on the shaft, and after pressing the moving ring back into the tension spring, it can actively rebound.
