Hose assembly failure analysis

1, symptoms: hose inner tube is very hard, has been cracking.
   Analysis: temperature of the inner tube is easily precipitated plasticizer, which is a flexible hose can be a plastic material. Entrained gas oil oxidation allows the inner tube. Occur in the rubber products such oxidation reactions can be cured. Oxygen and temperature, will greatly accelerate the hardening of the hose tube. Occurred inside the inner tube cavitation also have the same effect.
2, symptoms: hose cracking internally and externally, but the elastic material is still soft at room temperature deflectable.
   Analysis: The likely reason is that the hose when the ambient temperature is very low deflection. Most standard hose is rated to -40 degrees, and some AQP hose rated temperature is -49 degrees, usually military hose rated temperature is -54 degrees, and some thermoplastic hose rated temperature is -54 degrees, poly four vinyl fluoride hose rated temperature is -73 degrees.
3, symptoms: hose rupture, peel the outer layer of wire reinforced rubber examination found that the entire length of the hose irregular wire breakage.
   Analysis: This indicates the pressure of the hose in a highly frequent fluctuations. SAE American Automobile Association, the two-story steel braided hose impact testing required at 133% of the recommended operating pressure of up to 200 000 cycles. About four-spiral hose SAE impact test requirements of up to 500 000 cycles. If the number of pulses within the extrapolation in a short time, more than one million times, the best choice for the enhancement layer wound hose.
4, symptoms: hose rupture, but not displayed on the entire length of the hose with multiple wire breakage. May be more than one teflon hose.
   Analysis: This indicates that the pressure has exceeded the minimum burst strength of the hose. Recommended to use higher-strength hose, or hydraulic lines appear abnormally high pressure conditions can cause malfunction.

Block brake with external and internal style sheets hold two kinds

Block brake with external and internal style sheets hold two kinds :
① The holding brake blocks : one piece fitting is the length of stroke by manipulation device is divided into short stroke and long stroke block brake block brake . Short stroke block brake magnet mounted directly on the brake arm. When working around moving core pin rotation to achieve loose brake ; magnet is de-energized by the main spring tight gates . This brake compact, tight brakes and brake release moves fast , but the impact force . Long stroke brake block brake lever system can generate a large pine brake force , but the braking action is slow, suitable for large brake.
② inner sheets block brake : brake wheel brake block is located inside through the pedal , the brake lever and bumps block open , pressed tight inner surface of the brake wheel brakes, the brake pedal is released the spring back blocks and loose brake. This can also be hydraulic or pneumatic brakes and other manipulation. Zhang style brake blocks within a compact, dustproof , and can be used where installation space is restricted , widely used in various vehicles.
Block brake pad The standard applies to foreign holding dual brake blocks . Press the brake pad ( referred brake shoe ) and brake pad connection mode , and the brake shoe ends of the hinge shaft hole without sink hole into the following four categories:
Type B1 : rivet hole on the brake shoe , brake pad adhesive way connected , brake shoe ends of the hinge shaft bore no sink hole ;
B1C Type : brake shoe is no rivet hole type , way connected with the bonding pad system , brake shoe ends of the hinge shaft hole with sink holes ;
Type B2 : rivet holes on the brake shoe , brake pads connected with caulking , brake shoe ends of the hinge shaft is no counterbore end portion ;
B2C type : rivet holes on the brake shoe , brake pad coupled with riveting , brake shoe ends of the hinge shaft also has sink holes.
2 shaped brake disc brake is applied mine hoist brake system hydraulic actuators, accurate name would be: Normally closed rear disk brake cylinder , is currently used in more rear-mounted fuel tank , start the hoist when the output pressure hydraulic oil open brake , hoist to work, working brake, hydraulic station according to the conditions increase or decrease the pressure , the brake will provide braking force contrary , in the accident state, the hydraulic pressure Back to the residual pressure , the brake at maximum braking force in the shortest time to hoist parking .
