Leakage prevention and emergency treatment of high pressure steel wire braided hose

stayHigh pressure steel wire braided hoseIn the process of using, if there is an accident, the consequences will be very serious. Then, how to reduce and avoid accidents? Let's see how to effectively prevent the leakage of high-pressure steel wire braided hose.

(1) Correct installation

In addition to ensuring the quality of the rubber hose, it should also be assembled correctly, and the pipe clamp should be installed in the correct position, and no missing installation is allowed. Reasonable installation steps: first tighten the fastening nuts at both ends several times (do not tighten temporarily), then tighten the pressing plate bolts, determine the installation position, gently tap the rubber hose with a wooden hammer, and finally tighten the fastening nuts at both ends alternately several times with a torque wrench (the torque is 40~6on? M). If the inclination between the center line of the joint cavity and the horn head is too large, great external stress will be generated after the nut is tightened, resulting in damage to the rubber hose joint.

(2) Reduce resonance

The span of high-pressure steel wire braided hose is large, and the opening and closing of needle valve makes the hose produce strong high-frequency vibration, which is one of the important reasons for hose damage. Therefore, the middle part of the hose can be fixed on the adjacent bolts and other fixing devices with clamps to reduce resonance.

(3) Reasonable adjustment

Make the injection pressure of the syringe comply with the provisions of the operation manual, and the stainless steel metal hose can prevent the rubber hose from cracking due to the high injection pressure. When adjusting the operation advance angle, do not forcibly move the hose.

(4) Emergency treatment

If the high-pressure steel wire braided hose joint leaks, soft metal or plastic sheets can be cut into small rings, padded in the joint cavity, and then pressed on the horn head. You can also use a fuse and cotton thread to wrap a few turns around the shoulder in the tightening direction, and then tighten the joint nut. If necessary, temporarily apply soap or paste bubble gum, maltose, etc. on the nut seat.
Only by mastering the correct use process and emergency treatment of high-pressure steel wire braided hose, can we avoid losses and ensure operation safety.
