3gr screw oil pump should pay attention to the place and common faults

Note the following when using 3gr screw oil pump: 1. It is forbidden to run in the environment without liquid in the pump chamber. Before starting, inject the liquid into the pump body from the pump inlet and then start the screw pump to avoid the idling wear of the screw pump stator; Before starting, determine the running direction of the screw pump to avoid reversal; 3gr screw oil pump should pay attention to the place and common troubles when using 3gr screw oil pump attention:
1. It is strictly forbidden to run in the environment without liquid in the pump chamber. Before starting, the pump inlet is used to inject the liquid into the pump body and then start the screw pump to avoid the idling wear of the screw pump stator;
2. Determine the running direction of the screw pump before starting to avoid reverse rotation;
3. The screw pump that has been newly installed or opened for a long time is not suitable for immediate start-up. It should be filled with the appropriate lubricant or the liquid pumped by the screw pump. Botaibang uses the pipe wrench to pull the screw pump a few turns before starting;
4. If a high-viscosity liquid or an aggressive medium is to be transported, the pump cavity of the screw pump should be flushed with oil or solvent to prevent infarction from causing damage to the stator when the screw pump is started next time;
5. When not in use, the transmission medium in the pump should be excluded to avoid breaking the stator in the winter when the pump body is cracked or the ice in the pump is started next time.
6. During the use, the lubricating oil should be added in the bearing box on time. If there is seepage at the shaft end, the oil seal should be disposed or replaced in time.
Common faults and solutions when using 3gr screw oil pump:
1. The pump body is violently vibrating: the electric rotor may not be tared, or the coupling may be poorly connected, the bearing may be worn and twisted, and the parts of the rotating part may be loosened and split, perhaps because the pipeline bracket is not stable, etc., and the adjustment may be adopted separately. , reinforcement, replacement, etc.
2. Oil leakage or leakage of the pipeline: the nut may not be tightened when installed. If the leakage is not serious, oil sludge or asphalt slurry mixed with asphalt oil may be applied in the place where the air leaks or leaks, temporary repair You can apply some wet mud or soft pimple. If you leak oil at the joint, you can tighten the nut by hand. If the oil leaks seriously, you must disassemble it.
3, the filler overheating: more because the packing is too tight, the cooling oil does not enter the packing, or the shaft profile is damaged, the appropriate loose packing can be adopted, the sealing pipe is blocked, etc., the packing wear must be replaced with new one, before the installation in the oil Internal permeation, loading into the circle, the whisper should be staggered, so as to reduce oil leakage. After the last lap of packing is installed, the gland should be tightly installed, and the tightness should be adjusted during operation; Botou Taibang Pump & Valve Manufacturing Co., Ltd. The screw pump does not absorb oil or discharge oil: the reason is mostly that the bottom valve is stuck, the oil filtering department is fouled, the oil suction height is too high or the oil suction leaks, and the steering impeller may be inadvertent, the impeller flow infarction, etc., after checking one by one, The repair of the bottom valve, the root blockage, the steering, the cleaning of the impeller, etc., can be adopted separately.

When using the 3gr screw oil pump, we pay more attention to the small details, which can largely avoid some faults, and should be disposed of immediately after the fault is discovered, so that it can be used longer.
