The single stage double suction wall type centrifugal pump has the characteristics of stable operation, no water leakage, low noise, low failure rate, convenient maintenance, and less space occupation. It can transport liquids of different properties and provide the pressure and flow required for chemical reactions. Therefore, effectively prolonging the service life of the centrifugal pump and reducing the maintenance amount have a great effect on improving the economic benefits of the factory. In order to ensure the normal use of the equipment, a trial operation is required before use, and there are many points that need to be paid attention to. Let's talk about it in detail below.
The trial operation of single stage double suction wall type centrifugal pump should meet the following requirements:
1. The steering of the driver should be the same as that of the pump;
2. Identify the steering of the pipeline pump and the coaxial pump;
3. There should be no looseness in each fixed connection part, and the specification and quantity of lubricant added to each lubricating part should comply with the provisions of the equipment technical documents;
4. Parts with pre-lubrication requirements should be pre-lubricated according to regulations;
5. All indicating instruments and safety protection devices should be sensitive, accurate and reliable;
6. The crank should be flexible and no abnormal phenomenon;
7. The high temperature pump should be preheated before the trial operation, the temperature should rise evenly, and the temperature rise per hour should not be greater than 500 ℃; the temperature difference between the surface of the pump body and the process pipeline with the working medium inlet should not be greater than 4090;
8. Set up a connection device to eliminate the influence of temperature rise, and set up a bypass connection device to provide a cooling water source.
The conveying medium of single stage double suction wall type centrifugal pump:
1. Thin, clean, non-flammable and explosive media without solid particles or fibers.
2. Such as mineral water, softened water, pure water, clear oil and other light chemical media. It can be used to pump mildly corrosive media.
3. The main material of centrifugal pump is stainless steel.
