Submersible slurry pump, also known as submersible sand pump, submersible mud pump, submersible dredge pump, submersible suction pump, submersible pump, underwater dredging pump, etc., has the advantages of simple operation, low price and simple matching. The motor sneaked into the water during use, making it easier to manage without the need to build complex ground protection and fixtures. The agitating impeller directly contacts the deposition surface, and the concentration is controlled by the depth of the dive, so that the concentration control is more comfortable. It is suitable for conveying sediment, slurry, coal slurry, sand and other media containing large solid particles.
Submersible slurry pump is a kind of equipment with high working efficiency and stable performance. Usually, its gears are also very special when they are made. In order to run the equipment better, we need to do every part of it and work A good understanding is needed to ensure the quality of the product. Of course, we can't take a look at it together.
1. The gears of submersible slurry pumps commonly have straight teeth, helical teeth, herringbone teeth, and spiral teeth, and the tooth profiles mainly include involute and arc types.
2. In all products, small gear pumps mostly use involute spur gears, high temperature gear pumps often use variable gears, and melt pumps that transport high-viscosity, high-pressure polymer melts mostly use involute helical gears.
3. Because the gear and the shaft are integrated, its rigidity and reliability are higher than that of the gear pump manufactured separately from the gear and the shaft. The gears of foreign low-pressure gear pumps often adopt a square structure, that is, the tooth width of the gear is equal to the diameter of the addendum circle.
4. Among them, the width of the gear teeth of the submersible slurry pump used in high-pressure occasions is smaller than the diameter of the addendum circle. This is to reduce the radial pressure area of the gear and reduce the load of the gear and the bearing.
