Super hard material synthetic press integrated valve plate type hydraulic station

Abstract

The present invention relates to an ultrahard material synthesis presser integration valve plate type hydraulic station used in the ultrahard material synthesis equipment, consisting of an electric machine, an oil pump, an oil tank and a fluid pressure control system, which is mainly characterized in that a cross chute used for adjusting the position of the electric machine is arranged at the pallet of the electric machine, an oil pipe component which is easily knocked-down is arranged between the oil pump and the oil tank, an oil distributing tank is arranged at the bottom of the oil tank, an oil strainer is arranged in the oil distributing tank, the fluid pressure control system is provided with a secondary down loading controlling liquid way which takes an integration control valve plate structure. The hydraulic station has the advantages of good applicability, authenticity, manufacturability and maintainability, simple structure, rational and compact placement, reliable performance and convenient installation, operation and maintenance, in addition, the hydraulic station is capable of greatly shortening the decompression time of the supercharger, increasing the work efficiency, and well satisfying the requirement of the ultrahard material synthesis technique.

Description

Technical field [0001] The invention belongs to the technical field of superhard material synthesis equipment, in particular, it is used for an integrated valve plate hydraulic station of a superhard material synthesis press with a cylinder diameter of 550 or more. Background technique [0002] At present, in the superhard material industry, the hydraulic station with a cylinder diameter of Φ550 or more used in the six-sided top synthetic press is generally composed of oil tanks, motors, oil pumps, working fluid cylinders, superchargers, various control valves, hydraulic pipelines and pressure transmission. Due to structural design reasons, the composition of medium and other components often has the following defects: [0003] (1) The pressure relief procedure is a one-time pressure relief. Due to the large size of the supporting supercharger, the volume of the booster cylinder is also large, the pressure relief time of the supercharger is longer, the work efficiency is low, and...

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
