Hydraulic Suction Hose Pipe In The Production Of Problem Solving Methods

Problem solving method in production of hydraulic hose

One, the surface of the pipe ripple.

Hydraulic Suction Hose Pipe Reason: 1. The cooling is not sufficiently 2. The sealing ring size is inappropriate, forming a vibrating phenomenon.

Hydraulic Suction Hose Pipe Solution: Increase the size of the set of water intake or increase the distance between the mouth touch and sizing sleeve. Check the vacuum tank seal ring size is small, if small, replace or appropriately reduce the vacuum tank of the first section, increase the vacuum of the second section of vacuum trough.

Second, Surface hemp point (mainly internal wall).

Hydraulic Suction Hose Pipe Cause: 1. The raw material contains impurities, 2. The inner wall of the mouth touch and the core touch is not clean, 3. The local temperature is too high, causing aging.

Hydraulic Suction Hose Pipe Workaround: 1. Check the raw material, 2. Clean or transition for a period of time, 3. Check the temperature sensor.

III. Surface pits.

Hydraulic Suction Hose Pipe Reason: 1. Raw material tide, bubble burst, 2. The amount of water is uneven.

WORKAROUND: 1. Raw material drying, 2. Adjusting the water volume or replacing the sizing sleeve

Fourth, surface bright spots.

Hydraulic Suction Hose Pipe Reason: fixed diameter set of insufficient water.

Solution: Increase the fixed diameter set of water or the replacement of large diameter set of water

Fifth, the internal and external wall axial rough.

Reason: Raw material moisture content is too high.

Hydraulic Suction Hose Pipe Solution: Raw Material drying process

VI. Surface NOT Bright

Reason: Melt temperature is inappropriate or the raw material has the problem

Solution: Adjusting melt temperature or replacing raw material

7, Hydraulic Suction Hose Pipe outer surface scratches

Reason: fixed diameter sleeve, support plate or seal ring with gravel

Solution: Cleaning up sizing sleeve, supporting plate or sealing ring

8. Hydraulic Suction Hose Pipe Outer surface Waterline

Reason: fixed diameter set of local nozzle blockage, resulting in the individual nozzle water excessive.

Solution: Cleaning Up sizing sleeve

Nine, inner wall groove (more appearing in wall thickness tubing)

Reason: wall thickness is too thick, melt is difficult to cool, produce flow.

Solution: Try the center cooling system to reduce the temperature of the mouth touch and core.

Thickness of pipe wall uneven

Hydraulic Suction Hose Pipe Reason: 1 the mouth touch or the core touch bolt loose, the mouth touch clearance adjustment is inappropriate. 2 the mouth touch or the core touch temperature uneven, causing the material flow inconsistent. 3 the fixed diameter sleeve and the mouth feel wrong, spiral shunt shuttle or sieve mesh jam.

Hydraulic Suction Hose Pipe Solution: 1 fastening bolts or adjusting the mouth touch clearance, 2 check the heating coil and temperature sensor, 3 to regulate the fixed diameter sleeve and the mouth touch to the fold shunt shuttle or sieve mesh.

11. Hydraulic Suction Hose Pipe Low elongation at break

Cause: 1. The raw material is not good, 2. Increased orientation and cleanliness

Solution: 1. Adjust the process temperature, strengthen the plasticizing effect, 2. Increase the distance of the mouth touch and sizing sleeve.

12. Hydraulic Suction Hose Pipe Large Ellipse degree

Reason: Gravity

Hydraulic Suction Hose Pipe Solution: Add correction device (PE pipe manufacturer must establish strict Supplier evaluation procedure, select the appropriate raw material and handle the material according to the test situation.) High-quality polyethylene pressure pipe production of equipment to the comprehensive output capacity dependence is strong, pipe manufacturers in the equipment selection must be fully investigated and demonstrated, to choose to cost-effective equipment.
