How to correctly refuel the plywood cold press

The hydraulic plywood cold press plays an important role in the dry compressed air. For now, the plywood cold press has two types: screw type and hydraulic type. In the production of plywood, during the use of the cold press, the plywood will be plywood The hydraulic plywood cold press is troubled by the correct refueling work, so the plywood manufacturer wants to solve this problem, reduce the failure rate of the cold press, and extend the service life of the plywood cold press. The hydraulic plywood cold press should be correctly adjusted according to the following content Carry out refueling operations.

Place the hydraulic plywood cold press maneuver arm parallel to the track direction, and stop after turning to the left by 45°, extend the bucket cylinder piston rod of the plywood cold press machine, retract the bucket cylinder piston rod, and slowly fall down Boom, put the bucket on the ground, then turn off the engine, turn on the fuel tank bleed valve, pull the operating handles back and forth, and step on the pedal several times to release the residual pressure of the system composed of its own weight.

Use gasoline to clean the pipe joints of the plywood cold press, the joints of the pump and the motor, the oil drain plug, the top fuel filler cap and the bottom drain plug of the fuel tank and their surroundings. Open the oil valve and the oil drain plug at the bottom of the oil tank, so that all the old oil of the plywood cold press machine flows into the oil drum containing the waste oil.

Open the oil filler cap of the oil tank of the hydraulic cold press, take out the oil filter element of the plywood cold press, and check whether the remaining oil at the bottom of the oil tank, edges and corners contains metal powder or other impurities. To clean the oil tank of the plywood cold press, first clean it twice with diesel oil, and then dry the inside of the oil tank with compressed air. Check whether there are any remaining sludge, impurities, etc. at the inner corners, until the cleaning stops, and then flush it with new oil at the end.

Disassemble the oil pipes of the plywood cold press. Remove the filter elements of all filters in the system. When replacing the filter element of the plywood cold press, carefully check the filter element for metal powder or other impurities, so that you can understand the wear condition of the parts in the plywood cold press system. Drain the old oil in the main hydraulic pump, reversing motor, and walking motor cavity of the plywood cold press, and fill it with new oil.

Before operating the plywood cold press machine tool, you must read its operating instructions to understand its performance and correct operation methods. The machine must be connected with a firm grounding device before connecting the power supply. The power cord of the plywood cold press machine tool needs to be connected to a power supply with a maintenance switch, and check whether the voltage and frequency of the power supply are appropriate. Before operating the plywood cold press, you must first confirm whether the working direction of the plywood cold press motor is correct. If it is not correct, you must change the wiring direction of the power phase line of the plywood cold press.
