IHG vertical pipeline chemical centrifugal pump

IHG vertical pipeline chemical centrifugal pump

Capacity: 1~1200 (m³/h) 

Head: 8~150 (m)

Temperature: 0-80℃ (℃)

IHG vertical pipeline chemical centrifugal pump
IHG stainless steel vertical pipeline pump features:
1. The pipeline pump is of vertical structure, the inlet and outlet are the same diameter, and they are located on the same center line. They can be installed in the pipeline like a valve. The shape is compact and beautiful, the floor space is small, and the construction investment is low, such as adding a protective cover. Can be placed outdoors.
 
2. The impeller is directly mounted on the extension shaft of the motor. The axial dimension is short and the structure is compact. The pump and motor bearing are arranged reasonably, which can effectively balance the radial and axial loads generated by the pump operation, thus ensuring the smooth operation of the pump. The vibration noise is very low.
 
3. The shaft seal adopts mechanical seal or mechanical seal combination. It adopts imported titanium alloy seal ring, medium-sized high temperature resistant mechanical seal and hard alloy material, wear-resistant seal, which can effectively increase the service life of mechanical seal.
 
4. It is convenient to install and repair, no need to dismantle the pipeline system, just remove the pump joint nut to extract all the rotor parts.
 
5. The pipeline pump can adopt the series and parallel operation mode of the pump according to the requirements of use, ie flow and head.
 
6. The pipeline pump can be installed in the vertical and horizontal directions of the pump according to the requirements of the pipeline arrangement.
 
IHG stainless steel vertical pipeline pump working conditions:
1. Suction pressure ≤1.0MPa, or pump system maximum working pressure ≤1.6MPa, that is, pump suction pressure + pump head = 1.6MPa, pump static pressure test pressure is 2.5MPa, please indicate the system working pressure when ordering loans. When the working pressure of the pump system is greater than 1.6MPa, it should be separately filed at the time of ordering. In order to manufacture, the overcurrent portion and the coupling portion of the pump are made of cast steel.
 
2. Ambient temperature <40 ° C, relative humidity <95%.
 
3. The volume of solid particles in the medium to be transported does not exceed 0.1% of the unit volume, and the particle size is > 0.2 mm.
 
Note: If the medium is used with small particles, please specify when ordering, so that the manufacturer can wear a wear-resistant mechanical seal.
IHG type stainless steel vertical pipeline pump use:
IHG vertical stainless steel pipeline pump for conveying liquids without solid particles, corrosive and viscosity similar to water, suitable for petroleum, chemical, metallurgy, electric power, paper, food, pharmaceutical and synthetic fiber sectors, the temperature is - 20 ° C ~ 120 ° C.

IHG stainless steel vertical pipeline pump start and stop:
(1) Preparation before starting
 
1. Turn the motor fan blades by hand, the impeller should have no card grinding phenomenon and the rotation is flexible.
 
2. Open the inlet valve and open the exhaust valve to fill the entire pump chamber with liquid, then close the exhaust valve.
 
3. Move the pump by hand to make the lubricating fluid enter the mechanical seal end face.
 
4. Jog the motor to determine if the steering is correct.
 
(2) Starting and running
 
1. Open the inlet valve and close the discharge line valve.
 
2. Turn on the power. When the pump reaches the normal speed, gradually open the valve on the discharge line and adjust to the required working condition.
 
3, pay attention to observe the meter reading, check the shaft seal leakage, normal mechanical seal leakage <3 drops / min, check the motor, bearing temperature rise ≤ 70 ° C, if abnormal conditions are found, should be dealt with in a timely manner.
 
(three) parking
 
l, gradually close the spit pipe valve, cut off the power.
 
2. Close the inlet valve.
 
3. If the ambient temperature is lower than 0 °C, the liquid in the pump should be drained to avoid cracking.
 
4. If the vehicle is to be deactivated for a long time, the pump should be disassembled and cleaned and packaged for storage

IHG stainless steel vertical pipeline pump maintenance:
(1) Maintenance during operation
 
1. The inlet pipe must be filled with liquid, and the pump is prohibited from running for a long time under cavitation.
 
2. Check the motor current value regularly and do not exceed the rated current of the motor.
 
3. After long-term operation of the pump, due to mechanical wear, if the noise and vibration of the unit increase, stop the inspection and replace the wearing parts if necessary. The overhaul period of the unit is generally one year.
 
(two) mechanical seal maintenance
 
1. Mechanical seal lubrication should be cleaned without solid particles.
 
2. Mechanical seals are strictly forbidden to work under dry grinding conditions.
 
3. Before starting, the pump (motor) should be driven several times to avoid the breakage of the graphite ring caused by sudden start.
 
4, seal leakage tolerance of 3 drops / min, otherwise it should be overhauled.
