Abstract
The invention provides a high speed and high power submersible pump and belongs to the technical field of manufacturing of submersible pumps. The high speed and high power submersible pump comprises a motor component and a pump component which are vertically arranged on a base, wherein the bottom of the motor component is a motor end cover; the top of the pump component is a volute; a lower bearing is arranged on a pump shaft between a motor top cover and the volute; a cylindrical bearing pedestal is arranged between the motor end cover and the volute; a sealing chamber cover is arranged at the bottom of the bearing pedestal; the motor end cover, the bearing pedestal and the sealing chamber cover form a closed oil chamber for accommodating the lower bearing; liquid lubricant is filled in the closed oil chamber; and the lower bearing is totally immersed in the liquid lubricant so as to be fully lubricated. The high speed and high power submersible pump breaks through the conventional grease lubricating for bearing; compared with the conventional submersible pump which adopts a grease lubricated bearing, the high speed and high power submersible pump has the characteristics of greatly increasing the limiting speed and prolonging the service life, along with rational design, simple structure, stable performance and the like.
Description
Technical field
The present invention relates to a kind of submersible pump, specifically a kind of high-speed high-power submerged pump.
Background technique
At present, most of high-speed high-power submerged pumps, the lubricating system of bearing all uses grease lubrication, because rotating speed is high, power is big, bearing is fragile, causes pump short working life.And because this submersible pump power is big, pump volume is also big, repairs the very big inconvenience of existence after the damage.
Summary of the invention
Technical assignment of the present invention is the deficiency to existing technology, provides a kind of and can improve the bearing limit speed, increases the pump high-speed high-power submerged pump in working life.
The technical solution adopted for the present invention to solve the technical problems is:
High-speed high-power submerged pump comprises the electric machine assembly and the pump assembly that are arranged in up and down on the base, and the bottom of electric machine assembly is an electric motor end cap; The top of pump assembly is a spiral case; Pump shaft between motor top cover and the spiral case is provided with lower bearing, is provided with columnar bearing support between electric motor end cap and the spiral case, and the bottom of bearing support is provided with the sealing chamber cap; Above-mentioned electric motor end cap, bearing support, sealing chamber cap surround a chamber, airtight grease chamber that holds lower bearing, and airtight grease chamber is filled with liquid lubricant oil in the chamber.
Be provided with the machine envelope in the chamber, above-mentioned airtight grease chamber between electric motor end cap and the pump shaft.
Be provided with down the machine envelope between above-mentioned airtight grease chamber chamber external sealed chamber cap and the pump shaft.
High-speed high-power submerged pump of the present invention compared with prior art, the beneficial effect that is produced is:
High-speed high-power submerged pump of the present invention is because the bearing grease of breaking the normal procedure is lubricated; Adopt grease lubricating bearing to compare with existing submersible pump; Have that reasonable in design, simple in structure, stable performance, bearing limit speed improve greatly, prolong working life, thereby the working life of having improved submersible pump greatly.
