Description

Technical Field

[0002] Nowadays, more and more large flange bolt tightening in oil refining, wind power, heavy equipment, etc. adopts hydraulic tensioners to assist in tightening. The hydraulic tensioner is driven by a hydraulic cylinder. When the cylinder is working, it needs to rely on an external hydraulic tensioning pump as a power source. As the energy supply device of the hydraulic tensioner, the hydraulic tensioning pump is internally provided with an oil tank for oil storage and an oil pump structure for pressurized oil delivery. Through the oil pump pressurized delivery, the hydraulic tensioning pump can provide a stable and reliable high-pressure oil supply for the hydraulic tensioner, and is a necessary energy supply equipment for the work of the hydraulic tensioner.

[0003] Since the pressurized delivery of oil depends on the operation of the pump body, vibration is inevitable when the pump body is working.

The connection structure is a rigid connection, which cannot weaken and slow down the transmission of vibration. It has a large noise when working. In addition, for the heat dissipation of oil, the existing hydraulic tensioner is only provided with a heat dissipation structure on the oil return side, and the heat dissipation effect is limited. After working for a long time, the oil temperature will rise sharply, which will affect the normal operation of the equipment.
