Medium barrel oil press manufacturer barrel oil press equipment

Introduction and working principle of oil press > Features: Save labor, save pressure, save energy and save electricity. This product adopts the world's advanced hydraulic system. The power source is an ultra-high-pressure combined hydraulic pump station. This power source has high and low speeds. The cylinder runs fast at low pressure and automatically slows down at high pressure.
>High oil rate. It is mainly used for squeezing peanuts, soybeans, tea seeds, flax seeds, white soil, animal oil, etc. It can also be used for dehydration of various chemical raw materials and fruits and vegetables.
> Mainly processes peanuts, soybeans, rapeseed, tea seeds, walnuts, sunflower seeds, corn and other oil crops. Stable performance, easy operation, durability and good oil quality. The equipment is simple to operate, durable, saves energy and labor, improves the oil yield rate, and the extracted oil is rich in fragrance, high quality and clean. It is an advanced equipment that replaces the traditional oil press.
Machine structure
>The oil press is composed of three parts: host hydraulic system, electrical control system
>) The hydraulic system adopts a new high and low pressure double pump unloading circuit. It consists of high and low pressure combined double pump, high pressure manual rotary valve, high pressure relief valve, medium and low pressure relief valve, hydraulic control one-way valve, shock-resistant electric contact pressure gauge, etc. It has the characteristics of compact structure, convenient operation, universal spare parts, reduced energy consumption, safety and reliability.
>) Working principle of the hydraulic system
>Startup: The motor starts, and the high- and low-pressure double pump outputs hydraulic oil back to the tank through the high-pressure rotary valve.
>Pre-pressure the high-pressure rotary valve to the right position, and the high- and low-pressure hydraulic oil of the double pump enters the upper chamber of the press cylinder through the high-pressure reversing valve, and starts working from the beginning. Perform preloading.
>

Pressing: after the pre-pressing is completed. When the pressure rises to a fixed value, the low-pressure relief valve of the pumping station unloads, and the double pump high-pressure pump supplies oil for oil extraction. When the electric contact pressure gauge is adjusted to the pressure range, the motor is powered off. When the pressure drops to the fixed value , the motor starts, and the machine is pressed repeatedly to ensure a high oil rate.
>Pressure relief: After oil pressing, the high-pressure rotary valve moves to the left position, and the hydraulic oil output from the double pump enters the lower chamber of the oil pressing cylinder through the hydraulic control one-way valve. The pressure of the overflow valve is set to, the cylinder piston rod After retiring, the high-pressure valve turns to the neutral position and the motor is powered off.
