Compact energy-saving servo power unit

Abstract

The invention discloses a compact energy-saving servo power unit. The compact energy-saving servo power unit comprises an oil barrel, an oil inlet pipe, spur rings, a partition plate and water coolingpipes. An oil pump is arranged in an inner cavity of the oil barrel, and the oil pump is located at the circle center of the oil barrel. The oil inlet pipe communicates with the inner cavity of the oil barrel, an oil outlet of the oil inlet pipe is adjacent to an oil suction port of the oil pump and is separated from the oil suction port through the partition plate so that an arc-shaped flow pathcan be formed between the oil outlet of the oil inlet pipe and the oil suction port of the oil pump, and the water cooling pipes are arranged on the flow path. In the flow process of cooling oil withoil pressure, the cooling oil can constantly hit the inner cavity wall of the oil barrel due to centrifugal force, the multiple spur rings are arranged on the inner cavity wall of the oil barrel andarrayed into a layer in the longitudinal direction, the spur rings can puncture bubbles, the cooling oil is cooled under the action of the water cooling pipes, meanwhile, the water cooling pipes can hinder the flow of the cooling oil to prolong the stay time of the cooling oil in the inner cavity of the oil barrel, thus, the cooling oil entering the oil pump is sufficiently cooled, and bubble removal treatment of the cooling oil is also completed.

Description

technical field [0001] The invention relates to the technical field of servo power units, in particular to a compact energy-saving servo power unit. Background technique [0002] The working systems of injection molding machines, die-casting machines, and high-speed forming machines include hydraulic systems, servo systems, etc. In existing equipment, cooling oil is pumped from the oil pool into the hydraulic system to cool the hydraulic system. After cooling, the cooling The oil enters the cooler for heat exchange and cooling, and the cooled oil returns to the oil pool, and is pumped into the hydraulic system again for cooling, forming a cycle. [0003] Since the cooling oil has oil pressure when it enters the oil pool, agitation occurs in the oil pool, causing the oil to generate air bubbles. If the volume of the oil pool is large, the air bubbles will burst before being sucked into the pump body; but When the volume of the oil pool is small, the cooling oil will be sucke...

Problems solved by technology

[0003] Since the cooling oil has oil pressure when it enters the oil pool, agitation occurs in the oil pool, causing the oil to generate air bubbles. If the volume of the oil pool is large, the air bubbles will burst before being sucked into the pump body; but When the volume of the oil pool is small, the cooling oil will be sucked into the pump body before the air bubbles are completely broken by themselves and pumped into the hydraulic system for cooling. Due to the high pressure, the air bubbles will burst, causing the cooling oil pipe to vibrate and make noise. Time will cause damage to the valve body and tank body related to cooling oil delivery, so it is necessary to improve the above technical problems
