Technical background: ultra high pressure treatment equipment has a wide range of applications in fields such as powder metallurgy, chemical engineering industry, biological treatment, food processings.For filling up ultrahigh pressure biological plant blank at home, the applicant has proposed the patent of invention of 03258266.8 " integratedization ultrahigh pressure biological treating equipment " in 03 year, authorize already.Hydraulic control system in the prior art below 31.5MPa has been a mature technique, but in the environment of ultrahigh pressure, just should examine closely again for the application of concrete component.Proportional pressure control valve can satisfy the control to pressure, but the pressure maintaining performance under ultra-high pressure condition is not good enough, uses one-way valve energy pressurize but the closed loop control of EVAC (Evacuation Network Computer Model).At above situation, the hydraulic control system on extra-high tension unit should be done some design that adapts to particularity.
Summary of the invention:
The purpose of this utility model is to overcome weakness that hydraulic unit demonstrates under ultra-high pressure condition and special this programme--the hydraulic control system of-integrated ultrahigh pressure biological treating equipment that proposes of the reliability and stability that guarantee its work, it has adopted new technology, the ingenious one-way valve that utilizes hydraulic control is for closed loop control and the stable operation of realizing complete machine creates good conditions.
By as above design, the integrated ultrahigh pressure biological treating equipment hydraulic control system that the utility model proposed, it includes motor, pump, three-position four-way valve, proportional pressure control valve, oil cylinder, piston, it is characterized in that behind three-position four-way valve, having connected the one-way valve of pressurize, be connected with the two position three-way valve of controlling non-return valve in the outlet of oil pump, its proportional pressure control valve is installed in the place ahead of one-way valve.
Oil-way system structure in this programme is as follows, motor drags oil pump, the oil that pumps connects relief valve, three-position four-way valve and two position three-way valve simultaneously, the oil outlet of three-position four-way valve connects proportional pressure control valve and one-way valve, meet the upper end-hole A that pressure transducer, pressure gauge are sent into oil cylinder through the oil circuit of one-way valve, the lower end mouth B of oil cylinder takes back three-position four-way valve, and the oil outlet of two position three-way valve connects the control end of one-way valve.
Adopt this programme can embody following superiority: 1. in this hydraulic control system, adopt one-way valve to realize inclusion seal, the dwell time is long, and this is unapproachable with the proportional pressure control valve pressurize, and this one-way valve is controlled conducting with two position three-way valve, and utilization flexibly; 2. finish closed loop control by electricity liquid ratio relief valve, realize the stepless adjustable of loading velocity and discharge rate, and can realize the hierarchical loading and the unloading of different pressures, also can follow the tracks of signal instructions such as low-frequency sine, oblique wave, ladder, pulse and pressurize; 3. owing to adopt electricity liquid ratio relief valve, the pressure in the time of can adjusting release and the speed of release, the shock problem in the time of therefore can slowing down release reduces vibration and noise.
Description of drawings:
Fig. 1 is the schematic diagram of this programme hydraulic control system.
Embodiment:
The work characteristics of this integrated ultrahigh pressure biological treating equipment is the working pressure height, and the dwell time is long, and this hydraulic control system is designed for satisfying this technical requirements.It is to be made of motor 1, oil pump 2, relief valve 3, three-position four-way valve 4, two position three-way valve 5, proportional pressure control valve 6, one-way valve 7, oil cylinder 8, pressure transducer 9, pressure gauge 10, institute.Motor drags oil pump, the oil that pumps connects relief valve, three-position four-way valve and two position three-way valve simultaneously, the oil outlet of three-position four-way valve connects proportional pressure control valve and one-way valve, connect pressure transducer, pressure gauge and send into the upper end-hole A of oil cylinder through the oil circuit of one-way valve, the lower end mouth B of oil cylinder takes back three-position four-way valve, and the oil outlet of two position three-way valve connects the control end of one-way valve.In native system, use the one-way valve pressurize, improved the degree of reliability; One-way valve is controlled conducting with two position three-way valve, and utilization flexibly; Proportional pressure control valve is arranged in the place ahead of one-way valve, can intactly realizes closed loop control, guarantee to realize the performance of machine by cooperation with two position three-way valve; Concrete technical requirements when having used proportional pressure control valve also to realize supercharging and unloading can be avoided impacting and noise.
