Jiaozuo Zhenhuaxin Technology Development Co., Ltd. supplies the best quality air bags and complete machine products for the qp series of pneumatic caliper disc brakes. Our production process, technical team, efficient marketing and service, surpassing the appearance and internal quality of imported air bags, with a warranty period twice that of similar foreign products. Our after-sales service fully meets the needs of key engineering projects and high-end customers, and has established our excellent products for the national industry. The quality of the product comes from Zhenhua Technology's meticulous and meticulous carving of the entire series of air bag products in every production process. With every bit of effort and struggle, we have created high-quality products and quality. QP12.7 brake: This product has the following advantages: firstly, its refined appearance design and innovative aluminum casting surface treatment bring customers a brand new visual effect. Compared with steel castings, it greatly improves the appearance and internal quality, and reduces the weight of the entire machine. 2、 500000 reliability tests in harsh environments, comprehensive inspection and testing to ensure the reliability of every component and product before leaving the factory, and maintenance free for customers to use more confidently and safely. Therefore, we can propose a warranty period that exceeds twice that of similar foreign products to ensure effective use. 3、 The special heat treatment process for the aluminum casting of the front and rear covers of the air bag, as well as the machining method of the fully CNC lathe, controls the surface roughness of the air chamber machining to be above 0.4, greatly enhancing the long-term wear resistance of the front and rear covers, avoiding the wear of the "v" shaped sealing ring of the air bag during the working process, leading to air leakage, inability to open the brake, and the occurrence of malignant faults such as shutdown and production stoppage. 4、 The ingenious design and use of fully imported Italian "v" type seals enable the air bag to quickly expand without leakage during intake and contract in a timely manner during exhaust, ensuring smooth exhaust without resistance. This completely solves many problems such as seal wear, leakage, reduced braking force, and scrapping of the air bag after a short period of use. 5、 The air bag piston rod undergoes multiple processes of processing, wear-resistant plating and polishing treatment, with a beautiful appearance and no wear on the "v" type seal. Strict tolerance fit and concentric requirements are required for the front cover, shaft sleeve, piston rod, piston disc, etc. The clearance between the piston rod and shaft sleeve is 0.02-0.03mm on one side, allowing the entire piston to move flexibly and effectively ensuring the working thrust of the air bag. 6、 Strict quality monitoring of springs and reliability testing of each batch ensure that the springs will not experience fatigue damage, fracture, etc. under normal working conditions, effectively ensuring the braking thrust of the air bag and completely preventing major malignant accidents such as brake failure.

Model of pneumatic caliper disc brake: QP15, QP20, QP25.4, QP30, QP38, QP40, PA15, PDA14, PDA11 are all imported from Italy with ingenious design and use of "v" type seals, which enable the "v" type seals to expand rapidly without air leakage when the air bag is in working condition, and the "v" type seals to shrink in time when the air bag is in exhaust, so that the air bag can be discharged smoothly without resistance, completely solving the problem of seal wear, air leakage, and reduced braking force when the air bag is working, There are many issues such as scrapping after a short period of time, such as asbestos free brake pads, which are green and environmentally friendly. The installation of brake pads adopts a spring clamp type, making replacement convenient and fast.

Each type of brake disc diameter can be adjusted for four levels of braking torque. The matching air bag uses imported aluminum alloy air bags, which are reliable and stable in performance, good in sealing performance, small in size, and light in weight. According to the performance requirements, the brake pads are divided into A type, B type, C type, D type, and F type. The brake pads adopt a spring clamp type, with a unique structure and convenient and fast replacement; Can be equipped with a display device to directly display the working status of the brake; All power sources do not need to be set separately and can be used in parallel with existing air compression stations. In the gas supply line, the front cover and rear cover of the air bag are cast with special heat treatment technology and fully CNC machining methods. The surface roughness of the air chamber machining is controlled at 0.4 or above, greatly enhancing the long-term wear resistance of the front cover and rear cover, avoiding the wear of the "v" shaped sealing ring of the air bag during operation, leading to air leakage and the inability to open the brake, Malignant faults such as shutdown and production stoppage occur, such as: 1. Selecting QP12.7 type and A type air bags, with 6 springs and a left type installation of the air bag, with the order label QP12.7-A-6 left; 2. Select QPL12.7A and B type air bags with mechanical release display, and install the air bag on the right side. The order label is QPL12.7A-B-E1 on the right side. QP (CQP) 12.7 type
