Key points for the correct installation of water ring vacuum pumps

一、Install the pump body and mechanical seal part of the water ring vacuum pump

1. Install the static ring part of the mechanical seal on the pump body, and when installing the static ring part of the mechanical seal, you can use water to wet it and press it evenly into the pump body by hand. Be careful not to push too hard! After assembly, check whether the static ring part of the mechanical seal is tightly assembled with the pump body.

2. Press the pump body tightly on the motor and tighten the bolts. Be careful not to damage the static ring part of the mechanical seal.

3. Install the washer into the back cover of the motor, and then install the pump body, the front cover of the motor, the bearing, the rotor of the motor, and the inner bearing cover parts into the motor housing, and lock the bolts. Install the motor fan, retaining ring, motor guard, and screws in turn. After installation, place the end of the pump's motor fan shroud facing down perpendicular to the ground, ready to install the other parts of the pump.

二、Install the pump shaft and bearing part of the water ring vacuum pump

1. The pump shaft and bearing are loaded into the bracket from the non-driving end of the bracket, and the pump shaft can be installed into the bracket by knocking the outer ring of the bearing. Note: Spacers or sleeve tools should be placed on the end face of the bearing when striking to prevent damage to the bearing.

2. Install the bearing cover at the non-driven end and lock the bolts. The lock gasket and lock nut for mounting the roller bearing are tightened on the shaft, and then the lock lug of the lock gasket is bent into the groove of the nut to prevent the nut from loosening.

3. Install the washer, the bearing cover at the drive end, and lock the bolt. Rotate the pump shaft by hand, the pump shaft should rotate smoothly, if the pump shaft rotates tightly, the bolt should be slightly loosened, and the pump shaft should be adjusted to a relatively smooth rotation state. 4. Install the flat key, the shaft part of the coupling pump, the coupling pressing plate, and the locking bolt.

三、Install the impeller of the water ring vacuum pump

1. Press the impeller on the bearing, and ensure that the front end surface of the impeller and the pump body retains a clearance of 0.05~0.15mm. Place the vacuum pump horizontally and check the clearance. If the gap is too small, it may cause mechanical failure of the vacuum pump; If the gap is too large, it will cause the pumping rate of the vacuum pump to decrease.

2. After the gap between the impeller and the front face of the pump body is adjusted, the depth difference between the outer edge of the pump and the impeller plane is measured with a depth micrometer, and the adjustment gap is retained to determine the adjustment.

四、the overall installation of the water ring vacuum pump pump cover, disc

1. Place the foot of the motor facing the sky and the shaft on the ground in a horizontal direction.

2. The water ring vacuum pump cover and disc form a whole. Push the pump cover onto the pump body, taking care that the dowel pins should be aligned with the dowel pin holes of the pump body and disc. Bolt the pump cover to the pump body.

3. After the water ring vacuum pump is installed, turn the motor fan by hand, and the pump must rotate smoothly. If the pump does not rotate smoothly or there is a friction sound during the pump rotation, the pump cover should be disassembled, the impeller clearance should be checked, and the adjustment should be readjusted. The above is a few detailed installation points of the water ring vacuum pump, do not install it by mistake, if you do not understand, you should contact the manufacturer as soon as possible, and the installation test will be carried out by professionals.
