  The reason why the Hydraulic Press Brake brake is not working

  What is a brake? Brake is our daily talk about the brake or gate, is to move the machine to stop or slow the mechanical parts.

  So what are the brakes? Brakes are divided into Hydraulic Press Brake and block brake two.

  The role of the brake is obvious, and very critical, then when the brake failure how to do?

  Here we come to analyze the Hydraulic Press Brake common troubleshooting.

  Hydraulic Press Brake equipment is the way to convert the pedal force into the hydraulic energy to pass the braking force, and its transmission organization is simple, but the brake brake torque and pedal force into a linear relationship, if the tire and the road surface adhesion is satisfied, the car The braking force is linearly related to the pedal force. This function is called the brake pedal sense (commonly known as foot feeling), the driver can thus directly feel the various conditions of the car brake equipment can be normal, to quickly diagnosed. Hydraulic Press Brake system common faults are: brake is not working like a brake bite.

  First, the brake is not working

  1, appearance: the car in progress, the brake pedal pedal immediately, the car can not immediately slow down, parking. The brake deceleration is small, the brake interval is too long.

  2, reason:

  (1) pedal free travel is too large.

  (2) brake cylinder lack of brake fluid, or to offset the hole block, the main pump bowl, apron aging, swelling, deformation or tread.

  (3) brake master cylinder piston and cylinder wear excessive and loose oil leakage, Hydraulic Press Brake return valve seal bad, out of the valve valve hinge broken.

  (4) brake cylinder pressure bowl aging, swell, piston stuck, sub-pump piston and cylinder wear and excessive leakage of oil leakage.

  (5) Brake shoes wear severe, the brake gap is too large or the gap is reversed.

  (6) brake drum rounded, from the groove or wear too thin, brake shoe surface appearance of oil, ablation hardening, rivets revealed.

  (7) Hydraulic Press Brake system into the air, Hydraulic Press Brake or brake system temperature is too high, the pipeline brake fluid gasification, constitute air resistance.

  (8) tubing concave, joint loose leakage, brake hose aging, break or block.
