pvc pipe making machine consists of conical twin-screw extruder, vacuum forming equipment, Haul-off machine, cutting machine, stacker and other components, with good stability, and produced high, easy to operate, reliable. The production line can produce water supply and drainage pipe, the material is U-PVC, C-PVC, large diameter PVC. Configure the secondary shunt mold, with a low temperature. Extrusion in low pressure; water membrane sizing, to ensure high-speed pipe production.
Process Flow PVC Pipe Machine:
kinds of molds and auxiliary machines, it can produce all sorts of PVC plastic pipe, profile, plate material, sheet material, bar material and granulation.
2. The conical twin screws have applied oil cooling system. Barrel is cooled by special wind cooling system.

Features of our machine PVC Pipe Making Machine:
1. Model KRSJ series conical twin screw extruder is a kind of special equipment for extruding PVC compound. With different
3. The conical twin screw extruder system has applied special computer control. According to customers requirements, most reasonable structure of conical twin screw can be made so as to achieve best plasticity performance and material quality.
4. The conical twin screw is made by high precision special digital screw miller; extruding property can be highly harmonized. It has firstly introduced advanced technique of producing screw with variable pitch and depth, so that the material can be more softly sheared and cut.
5. The distribution box is specially designed, pull force bearing is fully imported, and the drive life span can be prolonged. It can bear larger extruding pressure.
6. The electrical system has mainly applied imported parts, it has multiple alarm system, and there are few problems which can be easily eliminated. The cooling system has applied special design, heat emission area is enlarged, the cooling is rapid, and temperature control tolerance can be ± 1degree.
The common fault valve and maintenance methods
Valve failure are: the valve can not be commutated or commutation slow, gas leak, electromagnetic pilot valve and so on. (1) The reversing valve can not change direction or change slowly, usually due to poor lubrication, the spring is stuck or damaged, oil or impurities stuck sliding parts and other causes. In this regard, should first check the work of the oil mist is normal; the viscosity of the lubricant is appropriate. If necessary, lubricate, clean the sliding part of the reversing valve or replace the spring and reversing valve. (2) After the valve is used for a long period of time, the sealing ring of the valve core is prone to wear and the valve rod and the valve seat are damaged. As a result, gas leakage in the valve, slow or abnormal valve operation, and other faults can not be reversed. At this point, the seals, stem and seat should be replaced or the reversing valve replaced. (3) If the electromagnetic pilot valve into the vent hole is clogged with debris and other debris, closed laxity, the activities of the core is stuck, the circuit is faulty, etc., can lead to the reversing valve can not be reversed. For the first 3 cases, clean the sludge and impurities on the pilot valve and movable iron core. The circuit failure is generally divided into two types of control circuit failure and electromagnetic coil failure. Before checking the circuit fault, the manual knob of the reversing valve should be rotated a few times to see if the reversing valve can be normally commutated under the rated pressure. If the commutation is normal, the circuit is faulty. Check, the instrument can measure the voltage of the solenoid to see if it has reached the rated voltage, if the voltage is too low, you should further check the control circuit power and the associated trip switch circuit. If the reversing valve can not be changed normally under the rated voltage, check whether the electromagnetic coil connector (plug) is loose or inaccurate. Method is, unplug the plug, measuring the resistance of the coil, if the resistance is too large or too small, indicating that the electromagnetic coil is damaged, should be replaced.
