Low Pressure Casting Machine Operation Guide

   For the mechanical failure problem of the hydraulic control system of the low-pressure Casting Machine being unable to rise, it is first necessary to check whether the pressure controller is turned on without any problems. If it is found to be closed, you need to turn on the main power switch. Then check whether the oil motor, electrical control circuit, and thermal relay are started, check the structure of the low-pressure casting machine, check the tightening condition of the pressure regulating plate inside the low-pressure casting machine, the degree of damage to the radio frequency connector, the oil leakage of the steam pressure valve, etc. . If the above abnormal conditions are found, corresponding preventive measures should be taken.

Common mechanical failures of low-pressure casting machines include:

      1. The hydraulic control system cannot rise.

 

      2. The rise level of pump pressure is too high.

 

Low Pressure Casting Machine Operation Guide

 

　　1. Except for management personnel, personnel who are unfamiliar with the structure and performance of the machine are not allowed to start the machine at will.

 

　　2. During the manual or semi-automatic operation of the machine, to ensure safety, the mold is not allowed to be inspected, adjusted, or cleaned.

 

　　3. When adjusting the machine in the inching state, if all moving parts are moving, please be careful not to allow the low-pressure casting machine to interfere and damage the machine.

 

　　4. If the machine has serious oil leakage, out-of-control operation and other abnormal phenomena (such as excessive noise, etc.), it should be stopped immediately to check and analyze the cause. The machine can only continue to work after troubleshooting. It is not allowed to produce machines in violation of regulations.

 

      5. The grounding of each electrical equipment (such as electric control panel, furnace control panel, operating console, insulation furnace, etc.) should be firm and reliable, and checked regularly.

 

      6. When the machine is out of service for a long time, the movable template of the horizontal mold mechanism should be lowered to the lowest position to prevent accidents.

 

      7. When checking the hydraulic system, please stop and wait until the pressure gauge pointer returns to zero before operating.

 

      8. When inspecting the holding furnace, please open the exhaust valve and operate it when the pressure in the furnace is zero.

 

　　If steam is sucked into the suction side of the hydraulic pump, check the cause before servicing. If the inlet filter is found to be clogged, it must be removed immediately. If the damage is serious, the relevant parts can be removed.

 

　　Sometimes, the noise of a hydraulic pump will increase after long-term operation. The reasons are as follows:

 

Low pressure casting machine

 

　　1. There is steam in the sealing part of the hydraulic pump shaft.

 

　　2. Air pollution from operating oil;

 

　　3. Activate residual oil reduction;

 

      4. The oil pump speed does not meet the standard;

 

      5. Axis movement of the oil pump and motor;
