Integrated solution of hydraulic and electrical system of Tire range testing machine
Our company for the supporting tire drum testing machine is a single motor, single drum, simplex engineering tire testing machine. The tyre is loaded on one side of the simplex drum and rotates at a constant speed with the drum.
The tire testing machine provides the tire durability test under the condition of straight motion and straight slip Angle. And can do the tire indentation test and puncture test. The drum diameter is 7 meters, which is the largest tire drum tester in China.
The loading cylinder control loop adopts the closed-loop control scheme of constant pressure source + proportional pressure reducing valve + force feedback, which can realize the stepless change of loading force, before the test tire guide drum contact. The piston rod extends rapidly (flow control) and slowly after the test tyre contacts the drum (pressure control).
The control loop of slip Angle cylinder and dip Angle cylinder adopts the closed-loop control scheme of constant pressure source + solenoid valve, speed regulating valve + position feedback, which can realize the position control of piston rod.
Hydraulic and electrical system integration solution for Distance adjustment device of two-roll mixer
The hydraulic system of the distance adjustment device of the two-roll mixer is specially developed and matched for the two-roll mixer of various sizes. It is mainly used to adjust the distance between two rollers and has the function of intelligent retreat. The two cylinders with built-in magnetostrictive displacement sensors are connected to the moving roller, and the displacement of the two cylinders is controlled by the intermittent oil supply of the electromagnetic directional valve, so as to control the distance between the rollers.
Advantages of hydraulic pitch adjustment
· The roller distance can be set remotely and the roller distance can be adjusted continuously with material
· The pressure sensor is used to sense the tension of the extruding material. When the hard foreign body enters the roller, it can realize the emergency retreat, avoid the injury of the stick, and save the broken pieces
· It can be made into a continuous production line with multiple open refining units, and the discharging speed is greatly accelerated.
Main technical parameters
· Rated flow basin:16L/min
Hydraulic and electrical system integration solution for

The hydraulic system solution of tire
The hydraulic system of tire retouching vulcanizer is designed according to the action requirements of the hydraulic tire retouching vulcanizer, which controls the action of the opening and closing oil cylinders and the after-loading oil cylinders, and is different from the hydraulic system of tire retouching vulcanizer.
The system adopts the combination of high and low pressure pumps to realize the fast no-load operation and slow pressurization action of the afterload cylinder. The rodless chamber of the afterburner cylinder is provided with a pre-relief valve to reduce the instant impact and vibration of the afterburner cylinder's return journey. The rodless chamber is also equipped with a pressure sensor, which can detect the pressure at any time when pressurizing and maintaining the pressure and send signals and make up the pressure to ensure the required added pressure.
