There are some differences and classifications
1) According to the installation methods ,it is divided into ISG vertical pipeline pump ,ISW horizontal pipeline pump
Difference:ISG inlet and outlet in the same horizontal plane ,ISW inlet and outlet bearing 90° vertical
2) According to the pump materials is divided into :ISG(W) Cast iron pipeline pump ,IHG(ISWH) Stainless steel pipeline pump
Difference :Cast iron can only convey non-corrosive liquids ,like some acidic or alkaline liquids ,it needs stainless steel .Stainless steel is divided into 304,316 and 316L
3) According to the motor ,it can be divided into :ordinary pipeline pump ,explosion -proof pipeline pump
Difference :some flammable and explosive liquids need to be pumped with explosion -proof pipeline ,such as alcohol ,oil
4)According to the temperature of the convey medium ,it is divided into :ISG(W) Pipeline pump ,IRG(ISWR) high temperature resistant pipeline pump
Difference :ISG can be conveyed below 80ºC liquid ,IRG can be conveyed below 120ºC liquid

who is the trouble of 2BV vacuum pump | who is 2BV vacuum pump or the possible cause of failure | Who is 2BV or vacuum to eliminate the reason | |||||||||||||||||
The motor does not start and there is no sound | Two power lines are broken | check wiring | |||||||||||||||||
The motor does not start ,there is a buzzing sound |
1) one wiring is broken and the motor rotor is locked
2) impeller failure 3) motor bearing failure |
1) drain clean pump if necessary and correct impeller
clearance 2) change impeller 3) replace the bearing |
|||||||||||||||||
When the motor starts ,the current circuit breaker Trips |
1)the winding is short circuited
2)motor overload 3) the exhaust pressure is too high 4) too much working fluid |
1)check the motor winding
2) reduce the flow rate of working fluid 3)reduce the exhaust pressure 4)reduce the working fluid |
|||||||||||||||||
Excessive power consumption | Precipitation is produced | Clean and remove sediment | |||||||||||||||||
No vacuum is produced |
1) No working fluid
2)serious system leakage 3)The rotation direction is wrong |
1) check the working fluid
2)repair the leak 3) change two wires to change the direction of rotation |
|||||||||||||||||
The vacuum is too low |
1)the pump is too small
2) the flow rate of working fluid too small 3) the working fluid temperature is too high(less than 15ºC) 4) corrosion 5) Slight system leakage 6) seal leakage |
1) use larger pump
2) increase the flow rate of working fluid 3)Cool the working fluid and increase the flow rate 4) replace the parts 5) repair the leak 6) check the seal |
|||||||||||||||||
sharp noise |
1) cavitation
2) the flow rate of working fluid is too high |
1) connect the gas shield
2) check the working fluid and reduce the flow rate |
|||||||||||||||||
leakage | The sealing gasket is damaged | check all sealing surfaces |
