离心泵资料(国外英文资料) Hot water pump The TLB, TLRB series is a single-stage centrifugal pump Model significance TLB: a spin-off centrifugal pump; TLRB: open hot water centrifugal pump; TLHB: the chemical pump; 200: the diameter of the pump import and export. 50: pump rating: (I) : traffic classification. Working conditions: The liquid temperature: 15 ℃, + 120 ℃ Working pressure: maximum working pressure is less than 1.6 MP (system pressure = entry pressure + pump lift is less than 1.6 MP.) The temperature of 40 ℃ or less of the surroundings Relative humidity is less than 95% The suction fluid is water, similar to clear water. The solid insoluble volume is no more than 0.1% of the volume of the monomer, and the granularity is less than 0.2 mm Prepare before starting: 1) rotary motor impeller, impeller without card grinding, rotating flexibly. Open the inlet valve, open the drain valve and fill the pump chamber with the drain valve. The pump should be pumped with a hand disc to allow the sealing oil to enter the sealing face. 4) deliver hot liquid, warm up before starting, heat in heat. 5) click the motor and turn to the right. Starting with the run Full open inlet valve and exit valve. Turn on the power supply to normal speed and gradually open the outlet valve. And (3) check the shaft seal leaks normal time to leak sealing ﹤ 3 drops/min) bearing temperature 70 ℃ or less. 4) the pump should release the sealing end screw for 500 hours. Fill the sealed cavity with oil and tighten the screw. No leakage. parking 1) gradually close the valve and power supply of the outlet line. 2) the import valve. 3) the environment temperature is lower than 0 ℃ will put liquid in the pump chamber to avoid frost crack. Maintenance and maintenance of pump The inlet pipe must be highly sealed, not leaking or gas. The pump is not allowed to operate for long periods of corrosion. 3) when pumping large quantity of water, it is forbidden to run the electrical current long. Check the electrical curren
