Super hard material synthetic press integrated valve plate type hydraulic station

Abstract

The invention is a superhard material synthesis press integrated valve plate hydraulic station for superhard material synthesis equipment, which is composed of a motor, an oil pump, an oil tank and a hydraulic control system. The cross chute to adjust the position of the motor; the oil pipe assembly that is easy to disassemble is installed between the oil pump and the oil tank; there is an oil distribution tank at the bottom of the oil tank, and the oil filter is installed in the oil distribution tank; road, and adopts an integrated control valve plate structure. The hydraulic station has good applicability, reliability, manufacturability and maintainability, and has a simple structure, reasonable and compact layout, reliable performance, convenient installation, operation and maintenance, and can greatly shorten the pressure relief time of the supercharger and improve work efficiency. It can well meet the requirements of superhard material synthesis process.

Description

technical field [0001] The invention belongs to the technical field of superhard material synthesis equipment, in particular to an integrated valve plate type hydraulic station for superhard material synthesis presses with cylinder diameters above Φ550. Background technique [0002] At present, in the superhard material industry, the hydraulic station with a cylinder diameter above Φ550 used in conjunction with the six-sided top composite press generally consists of a fuel tank, a motor, an oil pump, a working fluid cylinder, a supercharger, various control valves, hydraulic pipelines and pressure transmission. Due to structural design reasons, there are many defects in the following components: [0003] (1) The pressure relief procedure is a one-time pressure relief method. Due to the large supporting supercharger and the large volume of the booster cylinder, the pressure relief time of the supercharger is long and the work efficiency is low, so it cannot be adapted to supe...

AI Technical Summary

Problems solved by technology

[0003] (1) The pressure relief procedure is a one-time pressure relief method. Due to the large supporting supercharger and the large volume of the booster cylinder, the pressure relief time of the supercharger is long and the work efficiency is low, so it cannot be adapted to superhard materials. Synthesis of new process requirements

[0004] (2) The hydraulic station uses one valve plate or multiple valve plates. The former has complex oil passages and many inclined holes; the latter has relatively simple oil passages and fewer inclined holes, but since the valve plates are connected by external pipelines, the hydraulic station Complex layout, difficult pipeline fabrication and installation, many oil leakage points, and inconvenient maintenance

Especially for pumping stations with a cylinder diameter above Φ550, due to the large size, large number, and complex oil circuits of the hydraulic valves, a large number of inclined holes are used for the valve plate, which makes it difficult to process and manufacture the valve plate, low production efficiency, and difficult to guarantee the quality; moreover, the valve plate A large number of process hole plugs use welding plugs or taper plugs, resulting in difficult processing and poor sealing reliability

[0005] (3) The oil suction pipe of the oil pump, the oil return pipe of the valve plate and the oil tank cover are connected by flanges, and the oil pump outlet pipe and the valve plate are connected by steel pipes, and the motor can only be adjusted in one direction. When the oil pump is repaired and replaced, due to the oil pump, The manufacturing error of the motor and pump bracket, and the welding deformation of the oil pipe cause the installation size of the oil pump oil pipe to change, which makes the installation difficult.

[0006] (4) The oil in the fuel tank is filtered by a single filter element, and the impurities settle at the bottom of the tank, and the filter element is easy to block, which easily causes the working procedure of the hydraulic system to be disordered

When cleaning, the oil in the tank needs to be pumped out, and people need to enter the tank to clean up the deposited impurities. The cleaning takes a long time, the efficiency is low, and the work is dirty and heavy
