When summer comes, the maintenance and maintenance of the die-casting machine becomes very critical. As the temperature rises, there will be various small problems of the die-casting machine. So how to maintain the die-casting machine in summer? Longhua die-casting machine is Your detailed explanation: The main reason for the die-casting machine is that its summer is relatively hot, so the oil temperature will be about 20% higher than in the past.In this case, we need to perform necessary replacement and maintenance of the seals during the maintenance process. The reliability of its use can be guaranteed. Die-casting machines have a large demand for cooling water in summer, so the scale in the cooling system of the die-casting machine must be very large, so the waterway needs to be cleaned, and a scale cleaner should be used for cleaning and descaling. Check during the use of the die-casting machine Nitrogen is very sufficient, and ensuring sufficient nitrogen is the key to the use of die casting machine. Before the workers leave work every day, carefully check the oil stains on the die-casting machine, metal, etc., if it is necessary to clean the oil stains on the machine, etc., the most important thing in the maintenance and maintenance of each part of the die-casting machine finishing agent The cleaning of the shooting chamber, etc., clean up the garbage and foreign objects on all parts of the machine, so as to avoid damage to the die casting machine parts when it is turned on again. Check the die-casting machine oil tank, hydraulic pump, hydraulic cylinder, hydraulic motor, hydraulic valve, pipe joints and pressure gauges, and oil circuit board connections for oil leakage before leaving get off work every day. If the die-casting machine has oil leakage, it should be updated immediately. deal with.
