Overview of hydraulic transmission system for hot melt kettle

Introduction to Hydraulic Transmission System：

The hydraulic transmission system of the hot melt kettle mainly includes components such as hydraulic motors, multi-channel integrated hydraulic control valves, and hydraulic oil tanks.

① System characteristics

The application of multi-channel integrated hydraulic control valves can achieve continuously variable transmission function, provide strong torque, and ensure stable operation of equipment even under high load conditions. The hydraulic motor has forward and reverse stirring function, which can fully dissolve the coating. The capacity of the hydraulic oil tank is generally in the range of 70L to 80L, and it is equipped with a double-layer filter screen inside to ensure the cleanliness of the hydraulic oil and maintain the stable operation of the system.

② technical parameter

Hot melt kettles are usually equipped with a 15PS electric starting water-cooled diesel engine, which drives the mixing shaft through a gear pump, multiple hydraulic control valves, relief valves, and hydraulic motors. The flow rate of the hydraulic motor is generally 5.0L/min, with a torque of 698kg, which can ensure sufficient mixing force and no oil leakage. In terms of temperature control, the hot melt kettle is equipped with a bimetallic contact thermometer, which can accurately measure the temperature of the coating inside the kettle, thereby ensuring the efficiency and quality of the melt.

Working principle of hydraulic transmission system：

The working principle of the hydraulic transmission system of the hot melt kettle is grounded in the basic principle of hydraulic transmission. Through a hydraulic pump, the mechanical energy of the prime mover is converted into the pressure energy of the liquid, which is then transmitted to the hydraulic cylinder or motor via pipelines and control valves. Eventually, it is converted into mechanical energy to drive the movement of the working mechanism.

The basic principle of hydraulic transmission consists of the following steps: Firstly, the electric motor drives the hydraulic pump to draw oil from the oil tank, converting mechanical energy into hydraulic pressure energy. Next, the hydraulic medium enters the hydraulic cylinder through pipelines and control valves, pushing the piston to move. As a result, the worktable or other mechanisms are driven to perform linear reciprocating or rotary motions. Finally, the hydraulic medium returns to the oil tank, completing a working cycle.

In the specific application of the hydraulic transmission system in the hot melt kettle, the hydraulic system employs control valves and pipelines to transmit pressure energy to various parts of the hot melt kettle, such as heating plates and pressure regulating devices. By adjusting the movement speed and pressure of the hydraulic cylinder, the working temperature and pressure of the hot melt kettle can be precisely controlled, ensuring the stability and efficiency of the hot melt process.
