hydraulic components and hydraulic control system
Concrete Mixing Truck generally 7-8 months to complete an action molding cycle. From the design perspective, hydraulic molding machine easy process action, and moving machine parts is relatively small, relatively simple structure. So molding machine manufacturing companies around the world are producing the majority of hydraulic molding machines. Of course, does not mean that all hydraulic molding machines are used hydraulic transmission process action, if any, plus floor and floor molding machines and other devices are also transported by
mechanical transmission. It should also be seen molding machine hydraulic pump station, hydraulic components and hydraulic control system is more complex, it generally takes a professional manufacturer with manufacturing; especially the use of tanks, fittings and control valves and other hydraulic components are of poor quality , the failure rate is high, users are more troublesome maintenance. U.S. Bessel produced SUPERPAC, DY-NAPAC and cement mixing machine machine and other mechanical drive for the cam-type mechanical transmission, the motor pulley
driven through pneumatic clutch and brake, pneumatic clutch and brake pulley driven through a set of complete molding cam mechanism action, and reliability, the molding cycle is only 6-7 seconds, high production efficiency, block good quality, durable equipment, but a complex mechanism, the machine weighs 17-32
tons, more expensive.
