Chemical pump use rules

[Asia Pump Network News] Chemical pump is divided into the use of the rules of operation, operation, parking three parts, each part has its own requirements, the following is one of its three parts one by one introduction. Chemical pump use of procedures (1) start a, prepare the necessary tools. b, check the suspension body oil chamber of the oil level control in the centerline of the oil level about 2 mm position. c, check the motor rotation direction is correct, non-reverse. d, turn the coupling by hand, should feel relaxed and light weight uniform. e. When the pump is installed below the level, open the gate valve of the suction pipe before starting to fill the pump with liquid. If the pump is installed above the liquid level, pump or pump the air before starting, so that the pump and the suction pipe are filled with liquid and drain the air in the pump. f, close the import and export pressure gauge and pressure line pressure valve, starter motor into the export pressure gauge, open the outlet pipe valve to the desired location. (2) operation a, always check the pump and motor temperature rise, the bearing temperature should not exceed 75 degrees Celsius. b. Pay attention to the change of the oil level in the suspension body oil storage room. It is often controlled within the specified range. In order to keep the oil clean and well lubricated, the new oil should be replaced regularly according to the actual situation in the field. c, during operation, found abnormal sound or other failures should be immediately stopped inspection, to be able to continue to run after the failure. d, does not allow to use suction valve on the pipeline to regulate the flow, in order to avoid cavitation. e. The pump can not run for a long time under less than 30% design flow. If it must be used in this condition, a bypass pipe should be installed on the outlet pipe so that the flow of the pump can reach the use range. (3) parking a, slowly close the outlet pipe gate valve, stop the motor. b, close the import and export pressure gauge, filling the case but also close the suction pipe valve. c, if the ambient temperature is below the freezing temperature of the liquid, put the net liquid pump to prevent cracking. d, long time to stop using the pump, rinse with water, and the pump inlet and outlet sealed properly preserved.
