A wear-resistant and long-life energy-saving hydraulic transmission equipment

Abstract

The invention relates to energy-saving hydraulic drive equipment with wear resistance and long service life. The equipment includes a cylinder body, a piston rod, piston seal, an end cover, a reinforcement mechanism and two oil intake mechanisms. Each oil intake mechanism includes an oil transporting pipe, an oil inlet pipe and a filter assembly. Each filter assembly includes a filter box, a sealing plug, a support ring, a screen mesh and multiple fixing units. The reinforcement mechanism includes a connecting plate, a fixing plate, a translation assembly, a translation block, an insert pipe and a reinforcement assembly. The energy-saving hydraulic drive equipment with wear resistance and long service life filters and purifies hydraulic oil entering the cylinder body through the oil intakemechanisms to avoid the wear of the piston seal and shortening of the service life of the equipment caused by the entering of impurities in the hydraulic oil into the cylinder body. Furthermore, after the adjustment of the position of the piston rod is completed, an insert rod in the reinforcement mechanism is inserted into and fixed to the insert pipe on the piston rod to fix the position of thepiston rod, and so the equipment does not need to keep oil pressure in the cylinder body continuously, which saves energy consumption and improves the practicality of the equipment.

Description

technical field [0001] The invention relates to the field of hydraulic transmission equipment, in particular to an energy-saving hydraulic transmission equipment with anti-wear and long service life. Background technique [0002] Hydraulic cylinder is a device that converts hydraulic energy into mechanical energy to make the machine realize reciprocating linear motion or swing. Its transmission works smoothly and has high reliability. In the working environment, in the control process of industrial production, a large number of hydraulic cylinders are used. [0003] However, in the process of using the existing hydraulic cylinder, it usually needs to stay for a period of time after a single action is completed. The continuous strong support of the rodless cavity usually maintains the pressure of the rodless cavity to apply continuous hydraulic pressure to the piston, so that the piston rod stays still. Due to the need for continuous pressure maintenance, energy consumption ...

Problems solved by technology

[0003] However, during the use of existing hydraulic cylinders, it usually needs to stay for a period of time after a single action is completed. The continuous strong support of the rodless chamber usually keeps the pressure constant to apply continuous hydraulic pressure to the piston, so that the piston rod stays still. Due to the need for continuous pressure maintenance, the energy consumption is increased to a certain extent, not only that , when the external hydraulic oil enters the cylinder of the hydraulic cylinder, it is easy to carry some impurities. After these impurities enter the interior of the hydraulic cylinder, they are easy to adhere to the inner wall of the cylinder. After the sealing plug moves inside the cylinder, it is easy to be damaged by these impurities. Affected by wear, the sealing performance is reduced, and the service life of the hydraulic cylinder is shortened, which in turn reduces the practicality of the existing hydraulic cylinder
