Water ring vacuum pump parts to install what are the requirements? - - - - - -

a, install the vacuum pump and pump shaft bearing parts

1. The pump shaft and bearing from the support of the drive end installed in the bracket. By hitting the bearing outer ring, pump shaft can be installed in the bracket. Note: hit, block or sleeve tool should be on the end bearing, in case of damage to the bearings.

2。 Install the drive end bearing cap and tighten bolts.

3。 Install the gasket, drive end bearing cap and tighten bolts. Turn the pump shaft by hand, pump shaft shall be smooth rotation. If the pump shaft rotation close together, slightly loosen the bolt, adjust the pump shaft to make it smooth rotation.

4。 Installation of flat key, coupling, pump shaft parts, coupling clamp and locking bolt.

2, install the vacuum pump body and mechanical seal parts

when the mechanical seal static ring components are installed on the pump body, static mechanical seal ring parts can be wetted by water, and uniform pressure into the pump body with her hands. Be careful not to push too hard! After assembly, check whether static ring part of the mechanical seal and pump body assembly.

by pressure on the motor, pump body tight and screw down the bolt. Be careful not to damage the mechanical seal of the static ring parts.

install washer to the motor back cover, then the cover of a pump body, motor, bearing, motor rotor and the inner bearing cover parts installed to the shell, and lock bolt.

in order to install motor fan, retaining ring, cover and screw. After the installation is complete, the pump motor fan cover end down and perpendicular to the ground, ready to install the other parts of the pump.

3. Install vacuum pump impeller

1, the pressure on the bearing, impeller should guarantee the impeller and the pump devices for end face keep zero. 05 ~ 0. 15 mm gap. Horizontal vacuum pump and check the clearance. If the clearance is too small, could lead to a vacuum pump mechanical failure; If the clearance is too large, vacuum pumping rate will be reduced.

2。 Adjust the clearance between the impeller and pump devices for end face, with a percentage depth measuring the depth of the pump in vitro between flange and impeller plane is poor, to determine the retention of adjust the clearance.

4, install vacuum pump pump cover and disc

1. The motor cover vertically down on the ground.

2。 The disc into the pump body will be prepared. Ensure on the pump body is close to the diameter of the disc was 4. 2 mm and accurately positioning pin hole together.

3。 For the disk on one side of the pump cover seal surface evenly daub sealant continuously. After spray paint, will pump cover tray installed in the pump body and pump, and screw down the bolt. Installing a water pump cover, should pay attention to the ends of the cavitation protection tube must respectively installed on the disc and the corresponding hole of the pump cover.

5, vacuum pump, pump cover, the overall installation of disc

1, motor base, shaft is in the ground level.

2。 The pump cover and the disk to form a whole. Push the pump cover on the pump body, should pay attention to the positioning pin and the pump body and disc positioning pin hole alignment. The pump cover with bolt fastening to the pump body.

3。 After installation of pump, turn the motor fan by hand. The pump must be smooth rotation. If the pump rotation is not stable or are in the process of pump rotating friction noise, should remove the pump cover to check the clearance between the impeller and so on. To readjust.
