Embodiment Construction

[0008] see figure 1 , The hydraulic ceramic tile press of the present invention includes a liquid-filled oil tank 2 for storing hydraulic oil 1, and the liquid-filled oil tank is connected to a compressed nitrogen source 9 and a vacuum device 5 through a pipeline. The compressed nitrogen source 9 and the vacuum device 5 can be connected in parallel with the liquid-filled oil tank 2 as shown in the figure, or can be connected with the liquid-filled oil tank with independent pipelines. The source of compressed nitrogen can be bottled compressed nitrogen or bottled liquefied nitrogen. Vacuuming equipment can adopt reciprocating vacuum pump or vane vacuum pump. Compressed nitrogen is piped into the liquid-filled tank. The nitrogen pressure in the liquid-filled oil tank is greater than the atmospheric pressure, so as to block the air from entering the liquid-filled oil tank, and make the pressure in the liquid-filled oil tank meet the working requirements.

Abstract

The invention discloses a hydraulic ceramic brick press for prolonging the service life of hydraulic oil. The hydraulic ceramic brick press comprises a liquid charging oil tank used for storing hydraulic oil, wherein the liquid charging oil tank is connected with a compressed nitrogen source and vacuum-pumping equipment by pipelines, compressed nitrogen enters the liquid charging oil tank through the pipelines, and the nitrogen pressure in the liquid charging oil tank is higher than the atmosphere pressure. The invention also discloses a method for prolonging the service life of the hydraulic oil. The method is characterized in that air in the hydraulic oil-filled liquid charging oil tank of the hydraulic ceramic brick press is pumped out, and the liquid charging oil tank is inflated with the nitrogen so as to enable the nitrogen pressure in the liquid charging oil tank to be higher than the atmosphere pressure. The invention has the advantages of slowing down the aging process of the hydraulic oil, prolonging the service life thereof and reducing the frequency of replacing the hydraulic oil of the hydraulic ceramic brick press, thereby saving a great amount of hydraulic oil; and the manufacturing cost of the compressed nitrogen source is much lower than the hydraulic oil, and therefore the invention has great economic benefit. Besides, the invention does not need to make a large amount of modification to the existing brick press, thereby being easy to be popularized and implemented.

Description

technical field [0001] The invention relates to the field of hydraulic equipment, in particular to a hydraulic ceramic brick press. Background technique [0002] Hydraulic ceramic tile presses have a liquid-filled oil tank (or liquid-filled tank, air-filled oil tank, upper oil tank) that reserves a large amount of hydraulic oil. In the existing hydraulic ceramic tile press, the liquid-filled oil tank is connected with the air compressor, and the air compressor presses air into the liquid-filled oil tank, so that the liquid-filled oil tank has a pressure of about 0.15-0.25 MPa. Since the air contains oxygen and water, the hydraulic oil will undergo a chemical reaction in contact with oxygen and water, causing the hydraulic oil to age. Therefore, the existing hydraulic ceramic tile press needs to change the oil about 3 times a year. Although the oil loading capacity of a brick press varies with its tonnage, on average, the oil loading capacity of each brick press is about 120...
