 Installation and commissioning suspended roller cement pipe machine into what steps it?

 First, the pre-installation preparation

 An equipment-based preparations

 

 Hanging roller cement pipe machine is a device that is dynamic load larger (mainly vibration and shock) of. First products should be based on process requirements, the information provided by the equipment manufacturer and the specific conditions of use site design basis, as no design capacity of the unit, you should ask a professional design unit designs. The basis for the construction according to the basic design, basic strength after construction should reach more than 60% of concrete strength before installation. For larger machine sizes hanging roller, which is preferably carried out before installing the base preloading pressure of the weight of the pre-P:

P = 1.25 (P1 + P2 + P3)

Where P1 ---- suspended roller machine weight;

 P2 ---- 2 times the weight of the mold;

 P3 ---- Products 2 times the weight;

When the basis of acceptance of its size deviation refer to "reinforced concrete construction Acceptance" GBJ 10-65. On the walls of the hole to shovel aside hair and shovel out the φ30-φ50 mm pit, part of the foundation to increase secondary grouting integrity (increase fastness) buried the center target and the reference point. Center mark pasteboard, length (150-200) mm, width (30-60) mm, surface roughness should have better, it would be firmly planted on the basis of the surface, then the center of the punctuation mark, with the kind of red marked with red eyes, as the hanging wire and alignment equipment basis. Standard base plate exposed surface 4-6 mm. Red eye pencil uniform with a red circle around, so clearly marked. The reference point is the basis for measuring elevation, should be required buried.

Leveled surface around the foundation anchor bolts to make the place horn, adjust the horn.

Reserve base surface and the hole cleaned of all debris, put away the bolt and adjust the horn.

2, unpacking inspection

Third, the installation of electrical control parts

 

Control of electrical appliances are assembled in a control cabinet, the cabinet should be based on the process, the production site is arranged in the proper position, and conducted in accordance with the wiring of the equipment based on the device traces elevation below zero, while the wiring in accordance with wiring diagram .

 

Four, hanging roller cement pipe machine test dynamic change

 

1, pre-commissioning preparations

 

(A) familiar hanging roller machine manual and relevant information to understand the structure and performance of the equipment, to master its methods of operation, procedures and safety rules.

 

(2) to determine the pilot program: for participants and the division of labor, commissioning procedures, progress and achieve the requirements to be clear on the safety measures and precautions must also pay attention.

 

Installed base construction (3) equipment, devices, alignment adjustment, secondary grouting meet the design requirements, such as whether you want to be checked.

 

(4) Gather the necessary tools and materials.

 

(5) spare parts for equipment to conduct a comprehensive inspection, whether the missing parts, instrumentation, safety devices are complete, fasteners fastening is good. Place for all unqualified to be dealt with.

 

(6) Clear and commissioning of unrelated items.

 

2, empty commissioning

 

(A) motor, electronically controlled test run.

 

① Remove the triangle belt wheel motor and a host connection.

 

② a comprehensive inspection and electrical control circuit wiring.

 

③ triangular hand wheel toggle tape on the motor rotation with or without jamming.

 

④ start (first jog a few times) as normal, before officially starting the motor, start at a low speed, then according to operational requirements suspended roller machine for speed and run at various speeds in different grades and, if abnormal timely manner .

 

(2) fitted with triangular tape, manually enable the host spindle running, without jamming.

 

(3) Host commissioning

 

 First start the main motor (after several hosts normally jog operation), running in low gear a few minutes from the rotating parts and the sound functioning of the judgment are normal. The article can be molded as a normal process on the host governor and run on each gear speed. Running hand to observe whether the normal equipment operation, while retaining the speed of each test tachometer, and with the speed indicated on the electronic control instruments are consistent compare such error exceeds the allowable value must be adjusted so that the meter readings consistent with the actual functioning of the. Also check the electrical control system governor's smooth performance. In the test run should pay attention bearings temperature and, if abnormal reasons should be identified before running after troubleshooting.

 

3, load test

The prepared molds (such as the production of prestressed pipe should be installed in the mold of prestressed longitudinal reinforcement) mounted on the suspended roller machine, according to the whole process of molding products, first make an empty mold on hanging roller machine test run a cycle, such as there are problems should be treated in the operation of qualified cases, the suspended roller machine speed adjusted feed rate of the mold feeding, fed from dense, the whole process must be executed according to the production process requirements. Plus completion expected in dense process should select two halfway down the process (molding products shall not affect the emergence of phenomena such material slump), carried out starting at full load condition, in order to start the assessment device to reload capability. In the load test run in question can not react in an empty test out the reaction, so the first root test molding process officer must closely monitor the operation of the various parts of the equipment, if necessary in a timely manner to stop treatment. Temperature and sound operation of the equipment should be more concerned about, until forming qualified products, generally smooth molded three qualified products can be considered suspended roller machine installation and commissioning qualified; then suspended roller machine for the main performance once again detected on fasteners for review of key parts such as found loose or damaged fasteners, to identify the reasons for processing. And adjust the horn by welding equipment in prison.

 

Finishing commissioning information, acceptance procedures.

2, secondary grouting

Secondary grouting cement grade should be higher, should be properly added to the early strength agent, the secondary poured concrete curing period as short as possible, let it be when tightening bolt reaches more than 60%.

3, suspended roller shaft installation

 

During transport, the short axis is usually mounted on the back door shelves Ⅰ, Ⅱ minor axis of the spindle and unites shipped. Open the door arm during installation activities will be part of the spindle and the short axis Ⅱ hanging into the top rack, ball-type (also conical) bearing into the valve position, shut the door on the activities, so that the load bearing activities corresponding holes in the door inside. Then the other end of the axis is aligned with the minor axis Ⅰ and initially tighten by coupling bolts.

4, for the whole beginning of the tune and find positive

 

Suspended roller shaft at both ends of the spindle hanging edges to the center as the reference standard plate adjustment spindle (machine) axis position in the horizontal plane.

After the axis alignment, adjust the diagonal rack, perform the installation according to the technical requirements of the machine.

 

Whichever is the reference point, adjust the whole elevation (ie spindle elevation).

 

Suspended roller shaft alignment level degrees, with a framework so as to reach a level machine technical requirements. While adjusting the vertical column of the rack, especially the front door frame uprights, the activities should be open or closed doors without automatic phenomenon.

Bolt on both sides of the mat in the respective horn (each no more than three), real horn to pad, pad tight and expose equipment to the base 30-50 mm.

For each node, anchor bolts (foundation concrete strength should meet the design strength) to conduct a comprehensive inspection and tightening.

5, install power transmission components and parts
