Opened Type Impeller Centrifugal Water Pump For Sewage Waste Water
Description:
The pump shaft is supported by single-row annular contact ball
bearings. The bearings shall be lubricated with oil which should be
kept between the lines on the oil level indicator, or with grease
which has already been put into the bearing case during assembling,
it can be added after the front and rear end coves are dismounted,
or by oil holder.
The screwed hole on the top of pump casing is used for pouring
prime water into the pump or connecting, with a vacuum pump to
evacuate air and draw up water.
Feature:
1. The series of single-stage centrifugal pump casing and cover
make up of the operating room of pump. The impeller, shaft and ball
bearing make up of the rotor parts of pump. The hanger supports the
rotor parts of pump.
2. The axial and radial force of pump is borne by the ball bearing.
The axial sealing of pump is made up of packing gland, packing and
packing ring (mechanical sealing also can be used),which to avoid
gas to enter and greatly leak.
3. The shaft sleeve is installed on the position of packing to
protect the shaft to avoid the wear of shaft. Sealing ring is
installed between the shaft and sleeve to avoid gas to enter and
leak along the surface of shaft.
4. The front and back of impeller mostly has sealing ring to
balance the axial force, and there is balancing hole on the back
cover plate of impeller. If the axial force is not too big, there
no sealing ring and balancing hole on the back of impeller.
Application:
It can be used to transfer clean water or other liquids similar to
water in physical and chemical properties. It is suitable for
industrial use and urban water supply, pressure boosting for high
buildings and fire fighting, garden irrigation, long-distance water
transfer, heating ventilation and air controlling, circulation and
pressure boosting for cold and hot water, and supporting equipment
etc.
