Problems solved by technology
[0004] The device to pressurize the liquid generally adopts a high-pressure pump or a supercharger. The working principle of the supercharger is to change the liquid from low pressure to high pressure through different area ratios. The current supercharger generally adopts a one-way reciprocating The supercharger has the problems of slow supercharging speed, poor operation stability, complex structure, difficult maintenance and disassembly, and the supercharging efficiency of the supercharger is low

The invention discloses a double-acting pressurizer special for a water pressure testing machine for steel pipes. The double-acting pressurizer comprises a pressurizer cylinder, a pressurizer cylinder cover, a base, a high-pressure cylinder, a piston, a piston sealing ring, a cylinder body connector and a fixing flange. The high-pressure cylinder is connected with the pressurizer cylinder, a high-pressure cavity in the high-pressure cylinder is connected with a waterway system, and a pressurizer cavity in the pressurizer cylinder is connected with a hydraulic system. The piston comprises a piston head and a piston connecting rod which are connected. The piston head is mounted in the pressurizer cavity, the pressurizer cavity is divided into an oil pressurizing cavity and an oil return cavity, and the piston connecting rod always extends into the high-pressure cavity. Action area ratio of the oil cavity and the water cavity is used as pressure ratio, and pressure transmission can be realized by difference of an oil inlet and an oil outlet in the oil cavity of the hydraulic system, thereby double pressure ratio is realized, and production efficiency is effectively improved by interchange of the double pressure ratio.
Description
[0001] technical field [0002] The invention belongs to the technical field of boosting devices, and in particular relates to a steel pipe hydraulic booster. [0003] Background technique [0004] The device to pressurize the liquid generally adopts a high-pressure pump or a supercharger. The working principle of the supercharger is to change the liquid from low pressure to high pressure through different area ratios. The current supercharger generally adopts a one-way reciprocating The supercharger has the problems of slow supercharging speed, poor operation stability, complex structure, difficult maintenance and disassembly, and the supercharging efficiency of the supercharger is low. [0005] Contents of the invention [0006] In order to overcome the above-mentioned technical problems in the prior art, the object of the present invention is to provide a special double-acting supercharger for a steel pipe hydraulic testing machine, which has a simple and reasonable s...
