Maintenance and Maintenance of Foundry Machine 2019-06-04
In precious metal production and processing industry, continuous casting machine is often used for casting plate, rod, pipe and other products. The continuous casting machine is integrated with melting and casting. The design of mechanization and automation makes the whole machine highly efficient, flexible and convenient to operate. It is welcomed by gold and silver jewelry manufacturers. No matter what kind of mechanical equipment, it has a service life. As an important jewelry processing and production equipment, continuous casting machine must pay attention to the maintenance and maintenance of equipment in order to prolong its service life. There are 10 maintenance measures for continuous casting machine. Let's take a look at them separately. Frequently check whether the thermocouple has a circuit break or a short circuit. 2. The observation window is often cleaned and wiped clean with cloth and paper. 3. The heating ring should be blown clean by a common air gun to ensure that the ring is 2-3 mm away from the front of the ring and that no foreign body exists. 4. Check whether the conventional pressure is up to and ensure timely replacement. 5. The flow rate of cooling water should be checked regularly and the filters at the connection of pumps should be cleaned once a month. 6. Power supply check: input 380V/three-phase AC+5%. 7. Power outage treatment: In the casting process, if there is a power outage, the standby intake val

Fault Detection Editor 1. Temperature Loss in Casting Machine Fault Detection. In order to improve the heat preservation effect of the pouring machine, it is a pity that the lining of the furnace is only thickened. Firstly, the structure design of the casting machine is optimized, and the cover is divided into semi-fixed cover and movable cover, so as to minimize the area of movable cover and reduce the heat loss of movable cover. Because the semi-fixed cover does not need to be opened at ordinary times, it needs to be opened only when it is repaired. It can be made thicker and has better insulation effect. Secondly, the lining of pouring machine is divided into two layers, the inner layer is refractory layer, the outer layer is insulation layer, although the insulation layer is not thick, but the insulation effect is very good. Generally, the pouring machine with this structure can control the temperature loss within 2 degrees centigrade per minute. 2. The problem of drip leakage in gating machine fault detection. In fact, it is very simple to solve the problem that the bottom pouring machine often drips. Besides the plug of the pouring machine, it also rotates and tightens, which can greatly reduce the phenomenon of drip leakage of the pouring machine. Operational procedures 1. Check whether the equipment of pouring machine, electrical instruments, air passage, valves, etc. are normal, and whether the commonly used tools such as pry bars, hammers, etc. are ready. Discharge the water in the compressed air chamber. 2. When the core is laid, the hand is not allowed to close before leaving, in order to prevent crushi
