  • Deping DKQ Series Pneumatic Pipe Line-Up Clamp Maintenance Instructions
    2015-09-29

    This Pneumatic Pipe Line-up Clamp is mainly used in jointing pipe ends of two pieces of pipe being welded during long pipeline construction. Our DKQ Series Internal Pipe Alignment Clamp have already formed into series and the applicable pipeline diameter can be from10 inches to 80 inches. The power source is compressed air which is safe and environmental protective. These new generation Internal Pipe Lineup Clamp were developed by our company based on analysis of similar products from domestic and oversea. Its technical performance is excellent, operation is simple and the defect rate is low. Its line up precision can reach or exceed imported products of the same kind.

    This Pneumatic Powered Lineup Clamp adopted horizontal long frame structure which mainly consists of expanding device, traveling device, expanding guide, operating device and pneumatic system. After the Internal Pneumatic Clamp was put into the first welded pipe manually, the machine can travel forward and backward along the internal wall of the pipe by operating the switch, and can stop exactly at the position that need to line up. Two sets of clamp shoe of the expanding device can line up the two pipes that need to joint exactly, and expand to fasten.

    Under here are the brief introduction of Lineup Clamp machine maintenance :

    Mechanism Maintenance

    1、Check if the brake of Internal pneumatic pipe clamp operate reliably

    2、Filling in less lubrication to the root part of push rod of clamp shoes prior to working everyday, and move the push rod upwards and downwards continuously for several times. The proper amount of lubrication to be filled is not to overflow, in order to avoid pipe end contamiantion and not to affect the welding quality of pipe orifice. In case of the lubrication overflow, wipe it up in time please.

    3、 Regularly check the oil storage volume of lubricator; Check water storage capacity of the filter cup regularly, and discharge water in time.

    4、Open the outlet at the bottom of air tank to discharge water and dirt regularly.

    5、After each project is finished and prior to storage of equipment, the following work must be done:

    (1)Clean the equipment, wipe up oil stain and dirt.

    (2)Clean filter element of the filter, replace with a new one in time if damage.

    (3)Make up paint.

    (4)Spread grease onto all the motional parts exposed outside.

    (5)Open the outlet at the bottom of air tank to discharge all the sewage and dirt.

    Pneumatic system Maintenance Of Internal Line Up Clamp

    1 Regular maintenance includes daily check, weekly check, quarterly check and annual check (refer to schematic diagram of triplet )

    A、Daily check is to deal condensated water and dirt. In time discharge condensated water and dirt of air tank, air circuit and filter etc to avoid malfunction of reversing valve.

    B、Weekly check is to deal with lubricator. It can ensure to lubricate moderately reversing valve etc to avoid its malfunction due to bad lubricating effect.

    C、Quarterly check is to check leakage of reversing valve etc. and motion correctness and repair it in time.

    D、Annual check is to replace damaged components, it can ensure to thoroughly solve problems which always happen during use.

    E、Filter element shall be replaced after working hours around 5000 in total.

    Pneumatic circuit lubrication adjustment

    Keep motor running at unloaded condition, adjust the screw at the top of lubricator to ensure outflow rate 4~5 drops/minute. Fill oil into lubricator and discharge water in filter regularly.

    Our company has strong product design capabilities and has obtained dozens of utility model patents, With the reliable performance our products enjoy high reputation in China, Korea, Libya, Saudi Arabia, United Arab Emirates, Kuwait, Oman, Thailand, India, Argentina, Chile and Brazil so on.
