Medium-sized rapeseed oil press manufacturer rapeseed oil press equipment

Machine structure
>The oil press is composed of three parts: the host hydraulic system and the 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.
Equipment installation and inspection
>The oil press is packaged as a whole, easy to install, the machine is placed smoothly, and the equipment cannot be moved or moved in any way. The hydraulic oil of this oil press is anti-wear hydraulic oil, with simple winter use number and summer use number. Before filling, the inside of the mailbox should be kept clean. Hydraulic oil must be filtered through a mesh or above filter. The injection volume is. The service life of hydraulic oil is half a year. Hydraulic oil and filters should be replaced regularly, and the oil tank should be cleaned regularly.
For electrical installation, the power supply should be a three-phase four-wire AC power supply, and a leakage protector should be installed. After the power supply is installed, check whether the voltage is normal and whether the power indicator light (red) is on. Press the host button to check whether the motor is running normally.
