Centrifugal pump operation and use

Centrifugal pump operation and use Centrifugal pump test run should meet the following requirements: ① drive the steering should be the same with the pump steering; ② identify the pipeline pump and coaxial pump steering; ③ the fixed connection parts should be no loose, each Lubrication site filling lubricant specifications and quantity shall comply with the provisions of equipment technical documents; ④ pre-lubrication requirements of the site should be pre-lubricated; ⑤ all instrumentation, safety devices should be sensitive, accurate and reliable; ⑥ plate The car should be flexible, no abnormalities; ⑦ high temperature pump should be preheated before the test run, the temperature should rise evenly, the temperature rise per hour should not exceed 50 ℃; pump body surface with the working medium import process pipe temperature difference Should not be greater than 40 ℃; ⑧ set to eliminate the impact of temperature rise of the connection device, set the bypass connection device to provide cooling water. Centrifugal pump operation should pay attention to the following points: ① prohibit water-free operation, do not adjust suction port to reduce displacement, prohibit running at too low a flow rate; ② monitor the operation process, completely prevent packing box leakage, when changing the packing box With a new packing; ③ to ensure that mechanical seals have a full flush of water flow, water-cooled bearings prohibit the use of excessive water flow; ④ do not use too much lubricant; ⑤ check the recommended cycle. Establish operating records including operating hours, packing adjustments and replacements, adding lubricants and other maintenance measures and times. Centrifugal pump suction and discharge pressure, flow, input power, lotion and bearing temperature and vibration conditions should be measured regularly recorded. ⑥ Centrifugal pump host is relying on the atmospheric pressure will be low water pumping to a height, while the atmospheric pressure can only support about 10.3m of water column, so the host of centrifugal pumps leave the water 12 meters can not work.

When adjusting the laminate, the clothes hanging rod will change with the height of the laminate, the height of the clothes hanging space can be controlled freely, and will not cause any damage to the side plate.

Users can adjust the height of the laminate according to their preferences, so as to set their favorite hanging space, and truly realize the humanized "DIY". Moreover, considering that the clothes hanging rod is used to hang clothes, the load-bearing capacity is very important. It is easy to customize. The high-quality and solid aluminum alloy is used as the material of the clothes hanging rod to ensure its load-bearing capacity, and the anti-skid treatment is made on the clothes hanging rod, which is considerate and thoughtful.
