TOPTION brand SHB-95 vacuum pump
is a new kind of multi-use vacuum pumping machine
,it is designed on the basis of the principle of generating negative pressure by using the jet flow and using the recycled water as the working fluid.ISO & CE certified vacuum pump
excellent quality guarantee, by using vacuum pump, you could achieve the vacuum conditions for chemical experiments, and recirculated cooling water for the reaction equipment, rotary evaporator, etc.Under vacuum condition, material boiling point will decrease, finally make your research more accurate and efficient. -
Vacuum pump
is a most common laboratory equipment, how to achieve good maintenance of it, will help save many cost in laboratory research: -
No.
Common faults
Positions to be searched
Troubleshooting
1
Insufficient vacuum degree and inaccurate indication of vacuum meter
1. Low motor speed or
low voltage
Check whether the voltage is stable
2.Vacuum bottle or
check value is
clogged or corroded
by dirty materials
Clear the internal dirty materials or
replace with new bottle and valve core
3.Water inlet or filter pipe
network is blocked
Clean and take the internal dirt out
4. Vane wheel falls off
Replace the vane wheel
5. The phenomenon of
inflow or air leakage
happens to vacuum meter
Throw the water inside the meter and readjust the meter pointer to the state
of Zero, or replace a new meter
6. Vacuum pipeline is
blocked or cracked
Clean the pipeline or replace a new
meter
2
Motor does not work
1. The fuse is burned out
Replace a new fuse
2.Running capacitor is
broken down
Replace a new capacitor with the same
voltage as that of original capacitor
3. Motor winding is burned out
Replace a new motor
4. Seriously stuck for bearing wear
Replace a new bearing
5. Stuck for the blocking of
vane wheel
Clear the junk and correct the position
of vane wheel
6. Thread end is of rosin joint
or thread card is loosened
Weld firmly and Clamp the card tightly
3
Hot motor and
excessive noise
1. Bearing wear
Replace a new bearing
2. Wearing and deformation
of vane wheel
Replace a new vane wheel
3. Unstable or low voltage
Check whether the line is overloaded or
of low voltage
4
Water spraying inside water tank
1.Wrong water drainage
direction of filter pipe
Adjust the direction of water drainage
2. Too low water level
Add water to the level of overflow
mouth
5
Water leakage
1. Loosening of water release
nozzle or aging of seal ring
Screw the water nozzle tightly
or replace a new seal ring
2. Water tank cracks
Replace a new water tank
