pvc plastic hose extruder acceptance test

Core Tip: Extruder Acceptance Test Extrusion Machine After the installation of the production line by the production plant workers to clean up the extruder production line sanitation, do a good job cleaning of the equipment. Process technicians should be serious
Extruder acceptance test car
After the extruder production line is installed, the workers in the production workshop clean up the sanitation of the extruder production line and do a good job in cleaning the equipment.
Technical personnel should carefully read the extruder manual, according to the instructions required to develop test production of plastic products technology, test production operating procedures, test materials and test the use of test tools and test production time.
Organization of extruder production operators to seriously study the equipment operating procedures, to understand and be familiar with the structure of the equipment and the function of various parts of the function, memorize the function of the switches and buttons in the device and usage.
First, before the test preparation
① Check the extruder production line on each nut nut is loose.
② check the security shield is solid.
③ Check the degree of tightness of the V-belt installation, the appropriate adjustment of the belt to suit the operational requirements.
④ pull the V belt, rotation should be relatively easy, the parts run without exception, screw rotation without clamping phenomenon.
⑤ Check equipment and control box ground protection, electrical wiring, etc. Are there any loose phenomenon, whether it meets the requirements.
⑥ check the test motor and electric heating insulation resistance shall comply with the requirements.
⑦ Check the screw and barrel assembly clearance should meet the requirements.
⑧ each control knob should point to zero or stop position.
⑨ inventory special tools and accessories, neatly placed.
Second, idle running test acceptance
Extruder into the plant after the first acceptance test should be invited to supply, equipment management by the technical staff and equipment manufacturers to participate, led by the workshop leader production test.
① Check the lubricating parts of the equipment and gear box to ensure the quality of lubricants
Requirements, appropriate to add or add a sufficient amount of lubricant, lubricating oil level in the oil standard line height
Located.
② control box circuit closing power supply.
③ start lubricating pump, lubricating oil input parts of the lubrication, check the working position of the lubricating oil is correct.
④ Check the hopper, the barrel should be no foreign body.
⑤ lubrication pump start 3min, pull the V-belt should be flexible rotation, no blocking phenomenon.
⑥ low-speed start screw drive motor running.
⑦ observe the control box on the voltmeter, ammeter pointer oscillation whether there is an exception, the power consumption should not exceed 15% of rated power.
③ Check the direction of rotation of the screw (if the screw thread rotation is right-handed, then face the barrel, the screw should be rotated clockwise is correct) is correct.
⑨ listen to the transmission parts of the working sound is abnormal, see if the screw rotation friction with the barrel.
⑩. Check the delivery of oil, water, gas pipeline leakage.
⑩ stop the screw rotation. Exiting the screw, check the screw and barrel face without scratches. Such as screw or barrel scratch scratches should be negotiated with the equipment manufacturer, such equipment should be replaced.
⑩ … After cutting normal, the highest and lowest spindle speed (r / min) of the screw shaft should be checked and the conditions of the equipment manual should be met.
⑩ emergency stop button on the test equipment should be accurate and reliable work.
Third, air to turn the cylinder heating temperature test
