For the delivery of water and physical and chemical properties similar to the water does not contain solid particles of liquid. Widely used in industrial and agricultural city drainage, fire water supply. For the transport of 20 ℃ ~ 105 ℃ corrosive media or physical, chemical properties similar to the water medium.
IH stainless steel chemical centrifugal pump Features:
IH type stainless steel chemical centrifugal pump with water performance layout is reasonable, reliable, small size, light weight, good anti-cavitation performance, low power consumption, easy maintenance, high efficiency. IH single-stage single suction centrifugal pump for the horizontal structure, the structure of the basic design to meet all the pipeline installation.
Chemical centrifugal pumps are used in the chemical, petroleum, metallurgical, power, paper, food, pharmaceutical and synthetic fibers industries for the transport of corrosive non-contaminated water-like media
IH-type stainless steel chemical centrifugal pump Rotation direction:
IH type stainless steel chemical centrifugal pump through the extension of the coupling directly from the motor drive, from the motor side, according to clockwise rotation.
IH type stainless steel chemical centrifugal pump shaft seal type:
Packing seal: pump cover with stuffing box, the use of soft packing seal, stuffing box can be accessed through a certain pressure of water for sealing cooling, lubrication, cleaning.
Mechanical seal: single-end mechanical seal and double-end mechanical seal two types, sealed cavity into a certain pressure of water, flushing friction both ends, while the role of cooling.
The sealed type of the pump is sealed or mechanically sealed by the user and, as required, a seal type suitable for the sealing cavity size and other constructions suitable for ISO 3069, such as mechanical seals with bellows and impeller seals and many more.
IH stainless steel chemical centrifugal pump structure Description:
IH type stainless steel chemical centrifugal pump pump cover through the mouth fixed in the middle of the bracket, and then through the pump and the middle bracket to connect the mouth of the pump cover clamped in the middle, the pump is the axial suction, radial discharge, foot support , Can be directly fixed on the base. The suspension member is fixedly fixed to the intermediate bracket by a notch and supported by a suspension bracket on the base. For the convenience of disassembly, designed to extend the coupling, maintenance can not remove the import and export of connecting lines, pumps and motors. Simply remove the coupling of the middle of the coupling, you can exit the rotor parts for maintenance. This is a common international structure.
Stainless steel Chemical pump rotation direction: pump through the extension of the coupling directly from the motor drive, from the motor side, according to clockwise rotation.
IH stainless steel chemical centrifugal pump Scope:
IH type stainless steel chemical centrifugal pump conveying medium temperature is -20 ℃ ~ 105 ℃, if necessary, use double end seal cooling device, can transport medium temperature 20 ℃ ~ +280 ℃. It is used in the chemical, petroleum, metallurgy, power, paper, food, pharmaceutical, environmental protection, wastewater treatment and synthetic fibers industries to transport corrosive or non-contaminated water-like media.
IH stainless steel chemical centrifugal pump instructions:
1. ready before starting
(1) Before starting the pump and the scene clean up.
(2) Check the amount of oil in the bracket is appropriate (oil level in the oil level gauge center line 2mm or so) is good.
(3) before the coupling is not connected to check the main engine of the steering, and the pump steering arrows, then connect the coupling.
(4) in the installation of mechanical seals or packing and coupling can be easily turned by hand pump shaft, should be no rubbing phenomenon, and the coupling of the protective cover installed.
(5) pump in the case of suction use, should be pumped before the start of pumping or vacuum; pump in the case of the use of inverted, before the application of the liquid transported by the pump filled, the pump out of the air, shut down.
(6) Check the foundation bolts before starting. Whether the gland is skewed, and the supply of lubricating oil and cooling water.
(1) Close the inlet and outlet pressure (or vacuum) and the outlet valve (if there is a bypass pipe, it should also be closed at this time.) Start the motor (it is best to start before the pump is correct and confirm that the pump is turned correctly. ), And then open the inlet and outlet pressure (or vacuum) meter, when the pump reaches the normal speed, and the instrument pointed out the corresponding pressure, and then slowly open the water valve, adjust to the required conditions. In the case of the discharge line is closed, the pump can work continuously for more than 3 minutes.
(2) start the process to always pay attention to the prime mover power readings and pump vibration, vibration should not exceed 0.06 mm, the measurement site is the bearing.
(3) Sealing situation: mechanical seal should be no leakage, heat phenomenon, packing seal should be a continuous dripping state.
(1) often check the pump and the motor heat (bearing the temperature rise should not exceed 75 ℃) and oil level fuel supply situation. (Usually every 1500 hours after running, to replace all the oil once).
(2) can not use the suction valve to adjust the flow, to avoid cavitation.
(3) The pump should not be operated continuously at less than 30% of the design flow, and if it must be operated continuously under this condition, the bypass pipe should be installed at the outlet to discharge excess flow.
(4) Note whether the pump running noise, such as abnormal state, should be promptly eliminated or parking check.
(1) Slowly close the vents outlet valve (if the pump is used in the case of a backflush, turn off the gate valve of the suction line) and turn off the switch of the various instruments.
(2) cut off the power supply
(3) If the seal is used for external priming, also close the outer drawing valve.
(4) If the ambient temperature is lower than the liquid freezing point, it is necessary to put the liquid inside the pump to prevent cracking.
(5) If you do not stop for a long time, in addition to the corrosive liquid inside the pump put the net, the parts should be disassembled clean, especially sealed cavity. It is best to remove the pump after cleaning and re-installed, in addition to oil anti-rust treatment and closed pump into, exports, but also regularly checked.
IH stainless steel chemical centrifugal pump mechanical seal maintenance:
- because the mechanical seal is generally applicable to the use of clean, non-suspended particles in the medium, therefore, the newly installed piping system and liquid irrigation, should be carefully rinsed, to prevent solid impurities into the mechanical seal face and seal failure.
- in the easy crystallization of the medium, the use of mechanical seals should always pay attention to frequent washing. Before restarting the car, clean the crystal on the mechanical seal.
- the removal of mechanical seals should be careful not to use hand hammer, iron and another percussion, so as not to damage the dynamic, static ring sealing surface.
- if there is dirt can not be removed, you should try to remove the dirt, rinse and then disassemble, so as not to damage the sealing element.
- before installing the mechanical seal should check all the sealing components are invalid or damaged if any should be repaired or replaced.
- should strictly check the dynamic ring and static ring relative friction sealing surface does not allow any minor scratches, bumps and other defects. All other parts, including the pump body, impeller, sealed chamber, etc. should be rushed before assembly, especially moving, static ring end, use a clean, soft cloth or cotton carefully wipe clean, and then coated with a layer of clean grease Or oil.
- the assembly should pay attention to eliminate the deviation, tighten the screws, to even tighten, obscure the skew so that the seal failure.
- the correct adjustment of the amount of spring compression, pump installed after the hand to pull the rotor, should feel the seal spring both a certain amount of compression, but also light and flexible to turn the feeling of no bite. Such as feeling too tight or disk does not move, it should be appropriate to loose some.
- the external flushing of the mechanical seal, before starting should first open the rinse solution, so that the sealed cavity filled with sealing liquid. When stopping, stop the pump and shut the rinse.
