Hydraulic press operating environment and maintenance points

1. Check the parts of the single injection hydraulic press regularly, 1-2 times a month. Check whether various moving parts such as worm gear, worm, bearing, press wheel, upper and lower guide rail are flexible and wear, and if defects are found, they should be repaired in time.

Regularly clean the hydraulic valve and oil tank of the single injection hydraulic press, check or replace the sealing ring and filter element. Periodically filter the oil or replace the oil (the oil medium is 46# anti-wear hydraulic oil).

2, once the use is finished or stopped, the remaining powder should be removed. Scrub the powder residue from all parts of the machine. If the pressed powder is more fine powder or viscosity is too high, it should be cleaned once every two shifts. If the use time is longer, it is necessary to remove all the die, and clean the machine, the surface of the machine is coated with anti-rust oil, and covered with cloth.

3, the hydraulic press die should be placed in a covered tin box, and all immersed in oil, keep clean, do not rust and hurt. The place of use should be cleaned frequently, and the manufacture of medicine and edible tablets should not have gray sand and dust.

Electrical components should pay attention to maintenance, regular inspection, and maintain good operating condition. The cooling fan should be cleaned regularly with compressed air.

4, electrical components should pay attention to the working environmental conditions (temperature, humidity), in a good environment, will extend the service life of the parts.

5, the maintenance of electrical components should be carried out by professional and technical personnel, especially the frequency converter should be carefully engaged, and under normal circumstances should be sent to professional manufacturers for maintenance.

6, Before the electrical parts of the tablet press insulation test, it is necessary to remove all the main circuit control loop wiring of the inverter to avoid damage to the inverter by the insulation test. See the frequency converter operating manual for a separate insulation test method.
