This system uses hydraulic driving, pressure and displacement closed-loop automatic control mode to realize multi-point control, widely used in replacement of highway bridge rubber bearings, overpass lifting, synchronous lifting of inland river bridge, equipment lifting and rectification etc.
System Composition and Main Principle:
This system is composed of 1 high pressure pump station, control valve groups, hydraulic cylinders, stroke monitoring devices, pressure monitoring devices and 1 set of electrical control system.
Hydraulic pump station controls the flow by on-off valve, depending on regulating the switch frequency to change the flow which achieves the purpose of output flow can be regulated continuously. Accurate control on the synchronization of each hydraulic cylinder in lifting and load balancing in weighing process can be achieved by matching with proper electric control device, to compose pressure and displacement closed-loop control.

WHY DO YOU NEED SOV?
Q1: What's the brand name of your products?
A: Own brand "SOV", WE ARE GERMANY OWNED FACTORY. OEM is also available as required.
Q2: Hydraulic cylinder internal leakage?
A: There are 3 main reasons causing internal leakage: Overload, polishing is not well controlled, bad seal kits. As is known to all, vehicles in China are often overload, our products all designed to bear the overload power. We have numerical control machine to assure the polish processing .And we use the imported seals to meet customers' demands.
Q3: Does your piston rod get ruptured easily?
A: Hard chrome plating quenched and tempered 45# steel for piston rod to assure sufficient hardness and toughness.
Q4: Is your design reasonable? What about your product safe coefficient?
A: We have R&D team with abundant design experience. We also established production, education, and research cooperation with universities. Rest assured.
Q5: How about the delivery time?
A: Over 1000 sets advanced equipments to meet customer's large demand in short delivery time. Generally, it's 7-20 days.
