Maintenance of QJB submersible thruster

the submersible thruster consists of blades, reducer, main shaft, support and other components. The blades and spindles can be made of stainless steel according to the actual needs of the company, which is negotiating with the local Labor Committee and labor union according to the industrial Bayer materials technology. It is mainly used for mixing, stirring and circulation in the process of municipal and industrial sewage treatment. It can also be used as a flow pushing device for landscape water circulation. It can create water flow through stirring and effectively prevent the sedimentation of suspended solids. Although each equipment has been carefully inspected before leaving the factory, and the permanently lubricated bearing can maximize the durability of the equipment, in order to obtain a higher service life of the equipment, please carry out regular inspection and maintenance. 1. Cables shall be inspected irregularly according to working conditions and medium conditions, with special attention to the upper and lower water lines. If external damage is found, please replace it. 2. Check the motor insulation and fastening screws outside the equipment at least once a year. If the insulation resistance to ground of the motor winding is less than 5 megohm, please contact the after-sales service department of the company. 3. The lubricating oil replacement equipment has been injected with an appropriate amount of lubricating oil before leaving the factory, and shall be replaced after the first three months of operation. When replacing, lift the equipment out of the water with the oil plug in the oil chamber facing down, loosen the plug, drain the lubricating oil, clean the oil chamber with washing oil, drain the cleaning oil, inject an appropriate amount of lubricating oil, replace a new O-ring, and tighten the plug. Note: if the discharged oil is emulsified liquid, it means that there is water in the oil. Check again three weeks after oil change. If it is still emulsified liquid, check the mechanical seal. If necessary, replace the mechanical seal. After the mechanical seal is replaced, the oil chamber must be gas tested! If necessary, please contact the after-sales service department of the company. For routine maintenance, the lubricating oil should be replaced every six months. The lubricating oil is 32# machine oil or transformer oil. The cleaning oil can be gasoline or kerosene. 4. When the equipment is not used for a long time, it shall be cleaned, that is, the upper limit of the minimum guaranteed interest rate of 2.5% shall be canceled, and the equipment shall be lifted and placed in a dry and ventilated place. If placed in water, it shall be operated for at least 4 hours every 15 days. 5. In case of equipment failure, please follow the troubleshooting method indicated. If it still cannot be eliminated, and the cause cannot be determined, please immediately contact the service department after considering the performance and economy of the company's domestic plastic machinery enterprises, which have increased the development and sales of emerging markets of extruders in recent years. Do not dismantle or repair them without permission. Article source:
