Various types of stainless steel pipe pump transmission medium, working temperature and pressure are different, according to the medium properties can be divided into molten salt pump, stainless steel pipe, stainless steel pipe pump sulfate acid and alkali resistant stainless steel pipeline pump, water pump, stainless steel pipes, stainless steel pipe, liquid sulfur pump slurry pump. Stainless steel pipeline pumps are widely used in petrochemical industry, coal chemical industry, transport of different nature of the liquid, to provide the pressure of chemical reactions, flow. Therefore, the effective extension of the use of stainless steel pipeline pump cycle, reduce the amount of maintenance, to improve the economic efficiency of the plant has a great effect.
The choice and installation of stainless steel pipeline pump
Stainless steel pipeline pump should be carried out in accordance with the delivery of the liquid to choose, and check the performance needs, analysis of suction, discharge conditions, is intermittent or continuous operation, etc.. Stainless steel piping pumps are generally designed to operate under pressure and flow conditions at or close to the manufacturer's design requirements. Stainless steel pipeline pump installation should be carried out the following review:
According to the characteristics of the transmission medium of stainless steel pipeline pump, when necessary, should check the main parts, shaft seal and gasket material.
The 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, damage or corrosion etc..
Leveling the stainless steel pipeline pump, looking for work should be specified in the technical documentation in accordance with the equipment, if not specified, shall comply with the provisions of the current national standard "mechanical equipment installation engineering construction and acceptance of the" general specification.
All pump connected to the pipe fittings, wash oil pipe installation and requirements should be in accordance with the relevant national standards.
Effective measures to prolong the use period of the stainless steel pipeline pump
Two, the use of stainless steel pipe pump
The test run of the pump shall meet the following requirements:
1 the fixed connection parts shall not be loose, the lubricating parts filling lubricant specifications and quantity should be in accordance with the provisions of the technical documents of the equipment;
2 identify coaxial pipeline pumps and steering pump.
3 the steering of the drive unit should be the same as that of the stainless steel pipe pump.
4 pre lubrication requirements of the parts should be pre lubricated as required.
5 each indicating instrument, the safety protection device should be sensitive, accurate and reliable.
6 turning gear should be flexible, no abnormal phenomenon.
7 set the connection device to eliminate the influence of temperature rise, set the bypass connection device to provide cooling water.
8 high temperature stainless steel pipeline pump should be carried out before the test run, the temperature should be increased, the temperature rise should not be greater than 500 degrees Celsius, the surface of the pump body and the temperature difference between the inlet of the working medium should not be too high.
Stainless steel pipeline pump operation should pay attention to the following points:
1 lubricants do not use too much.
2 check according to the recommended cycle. Set up running records, including running hours, packing adjustment and replacement, adding lubricants and other maintenance measures and time. Pump suction and discharge pressure, flow rate, input power, temperature and vibration of the liquid and bearing temperature and vibration of the stainless steel pipeline pump should be measured regularly.
3 to ensure that the mechanical seal has a fully developed water flow, water cooling bearings to prohibit the use of excess water.
4 no water running, do not adjust the suction population to reduce emissions, to prohibit the operation of low traffic.
5 monitor the operation process, completely prevent the leakage of the packing box, replace the packing box to use the new packing.
