Do you understand? 2 bv vacuum pump bearing, impeller -

2 bv vacuum pump impeller adjustment

in order to ensure that 2 bv vacuum pump run efficiently, must be timely adjust the clearance between the impeller and the front baffle. Lined with metal pump impeller and stop the gap between 0. 5 - 1 mm, lined with rubber sheath before and after the pump impeller and the clearance between the. Equal to zero. When adjusting impeller clearance, should stop the pump, loosen bolts compression bearing components, and tighten the nut on the adjusting bolt to make the bearing assembly to move forward. At the same time, with the hand along the direction of rotation of the pump rotation axis, until the impeller and guard plate friction.

for pump with metal liner, loosen nut just tighten in the first half of the circle. Then tighten the front nut on the adjusting bolt to move back bearing components. At this point, the clearance between the impeller and the front baffle is 0. 5 - 1 mm。 For pump with lining, make through the nut screw to adjust the bolt bearing components to move forward. Impeller contact with former sheath, backward bearing components, the impeller and the sheath after contact, and then measure the bearing component of total distance of 2 bv vacuum pump. The distance is usually used as the clearance between impeller and sheath before and after. Using the adjusting bolt to adjust the location of the bearing components, to ensure that the impeller and the sheath gap between before and after the value is correct. Adjusted, before to start again, have to check whether normal rotating impeller, compressed bolt bearing assembly and adjustment bolts are tight, then start 2 bv vacuum pump.

2 bv vacuum water pump what advantage is there?

the seal using mechanical seal, the mechanical seal installation between the impeller and the pump body. Clearance between the impeller and pump body be determined by the mechanical seal. Cd-rom installed on 2 bv vacuum pump cover. The valve plate is equipped with a suction hole and vent the exhaust valve and a flexible plate. Flexible valve tray is used in air pressure between the impeller blades to exhaust pressure exhaust gas. Before discharge gas, the lower the power consumption caused by excessive gas pressure, which reduces the rate of consumption.

2 bv vacuum pump by the pump cover, valve, pump body, impeller, mechanical seal, motor and other parts. Trachea pipe through installed on the pump cover on the disc of the suction hole and vent connected to the pump cavity, the eccentric shaft is installed in the pump body, impeller by flat key.

2 bv on both ends of the vacuum pump clearance between the pump body and disc gasket between the regulation. Disc on the impeller and the water pump cover the gap between the disc and shim adjustment between the pump body. Coverage gaps between the disc can be determined from the entrance to the loss of gas in the outlet of the pump cavity volume and its extreme pressure.

in short, 2 bv main use vacuum pump mechanical seal, its mat mainly adjust the clearance between the pump and valve disc.

2 bv the effect of vacuum pump bearing body

1, the bearing body can be adjusted by bolts, and can adjust the bolt in suspension in the horizontal direction.

2, 2 bv vacuum pump bearing body can move in suspension, but there is no relative displacement in the bearing outer ring.

3, radial bearing in the water pump and motor side, and thrust bearing in motor side.

4, because there is no relative displacement, 2 bv vacuum pump oil seal can normal use.

5, shaft equipped with shoulder, bearing can be easily removed.

in short, 2 bv vacuum pump bearing seat after adjustment, easy disassembly and assembly. It is an indispensable part of equipment. When cleaning, please pay attention to protect the parts, and periodic inspection and repair, the correct method of use can also protect.
