Centrifugal pump to extend the service life of a centrifugal pump selection and installation Centrifugal pump should be transported in accordance with the liquid selection, and check the required performance, analysis of suction, discharge conditions, is intermittent operation or continuous operation. Centrifugal pumps should normally be operated at or near the pressure and flow rates specified by the manufacturer's design. Pump installation should be carried out the following review: ①The basic size, location, elevation should meet the design requirements, anchor bolts must be properly and correctly fixed in the concrete foundation, the machine should not be missing parts, damage or corrosion, etc .; ② According to Pump the characteristics of the transmission medium, if necessary, should check the main parts, shaft seals and gasket material; ③ pump leveling, find work should be consistent with the provisions of equipment and technical documents, if there is no provision should be consistent with the existing national standards " Mechanical equipment installation engineering construction and acceptance of common norms "provisions; ④ all connected with the pump pipe, pipe fittings and lube oil pipeline cleaning requirements should be consistent with the relevant national standards. 2, the use of centrifugal pump test run the pump should meet the following requirements: ①drive the steering should be the same with the pump steering; ② identify the pipeline pump and coaxial pump steering; ③ fixed connection parts should be no loose, the lubrication Parts 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 disc 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 inlet pipe temperature difference is not Should 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: ①prohibit 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.

Fireproof calcium silicate board
DISTINGUISHING FEATURES
1, fireproof insulation:
Grade A non-combustible,noncombustible.
No toxic fumes;
low conductivity coefficient;
ideal insulation material.
2, waterproof: Under conditions of semi-open air and high humidity, maintaining stable performance,no sag or deformation.
3, heat insulation: low thermal conductivity, good insulation properties, high product density, sound insulation.
4, light weight &high strength: pressurized by hydraulic machine flat plate of 10,000 tons, the product keeps a high strength, not easily deformed or warping and also has a low weight, suitable in roofing and ceiling.
5, easy building-construction: Dry operation; simple and fast installation of the keel and the plate; deep processing products have better performance characteristics.
6.beauty and practicality: Being lightweight and fit to the keel, effectively reduces the cost of construction and decoration;
board facing color agrees equably with no roughness, which makes all the building color in a unity.
7, safe and healthy: actually-measured radiation value equals to that of lawn 20 meters away from the buildings,which is below the national "Radiological protection standard for building materials" .
8, long service life: Acid alkaline, corrosion - resistant, non - cracking, healthy from pests and moisture,the board`s strength
and hardness are enhanced, ensuring a long service life.
9, good processability and performance in re-decoration: the board can be sawed, drilled, engraved and painted according to the actual situations.
