High-viscosity internal gear pumps are also called high-viscosity gear pumps. Users need to pay attention when using high-viscosity internal gear pumps.
First of all, what we need to do before we start, we need to check whether the oil in the gear box is enough, and the lubricating oil needs to be changed regularly. The general time for changing is about 4,000 hours of use. Before starting, you need to open the inlet and outlet gates of the pipeline. When the medium enters, you need to turn the high-viscosity internal gear pump by hand. After confirming that it is normal, it can be run officially, and the pump cannot be run when it is empty.
There is also the need to pay attention to the high-viscosity internal gear pump during operation. When it is running, we must pay attention to the power of the motor and the running condition. If there is an abnormality, stop the operation to find the cause. The pump body sealed with packing can allow one to three drops per minute. If it exceeds, the material ring should be tightly pressed. The mechanical seal should be free of leakage and heat generation. SS High-viscosity gear pumps In the petrochemical industry, the transportation of high-viscosity liquids (such as synthetic rubber, resin, fiber polymer liquid, etc.) is one of the main consumption processes, and the machinery used to complete the liquid transportation is in various ways Pump. Because the viscosity of the original liquid is relatively high, the suction resistance of the pump is relatively large. In order to ensure the self-priming ability of the high-viscosity internal gear pump, a positive displacement pump is usually used to transport high-viscosity liquids. The high-viscosity internal gear pump is a simple type of positive displacement pump because of its simple structure, light weight, low cost, limited viscosity transition, and insensitive to dirt in the liquid. The pump has good suction performance under high viscosity. , The work is reliable, so it is often used in places with harsh conditions and low precision requirements to transport high-viscosity liquids. The output displacement and flow of the pump are large, and the flow pulsation is small. So that the new product has a higher added value and competitive advantage, it provides a new way to deal with the lack of traditional two-gear gear pumps, and can replace the existing traditional gear pumps, screw pumps, etc., in petrochemical, light industry, The development and application prospects of high-viscosity liquid transportation in food and other industries are promising. my country's current development and application in this area are still very few, and there is plenty of room for development.
