The role of TPMS is to conduct real-time automatic monitoring of tire pressure while the car is in motion and to alert the tire for leaks and low air pressure to ensure driving safety. At present, TPMS can be divided into direct tire pressure detection system (PSB) and indirect tire pressure monitoring system (WSB).
WSB needs to compare the speed difference between tires through the anti-lock brake system (ABS) wheel speed sensor of the car to achieve the purpose of monitoring the tire pressure. The PSB is a system that uses a pressure sensor mounted on a tire to measure the air pressure of the tire and uses a wireless transmitter to send pressure information from inside the tire to the central receiver module.
Due to the advantages and disadvantages of these two systems, Tianhe combined the advantages of the two systems and developed a hybrid TPMS system. TRW expects the system to be put into production in 2013.
The spring cone crusher has a perfect combination of high-performance crushing chamber and high crushing frequency, which greatly improves the crushing capacity. At the same time, it also absorbs the principle of laminated crushing, which to a certain extent reduces needle like materials. The spring safety system is an overload protection device that provides "spring type" over iron release protection for foreign objects (iron blocks). Under normal use, the equipment has a fault free operation rate of over 95%.
Operational Principle:
The spring cone crusher uses a working surface between a movable cone and a stationary cone to crush ore. The moving cone is supported on a spherical bearing and fixed on a suspended vertical axis, which is placed inside an eccentric sleeve, which in turn is placed on a thrust bearing. The moving cone and the vertical shaft are driven by an eccentric shaft sleeve, which is driven by a horizontal shaft and a belt pulley, and transmitted through an bevel gear. The pulley is driven by an electric motor through a V-belt. The lower part of the vertical axis is installed into the eccentric sleeve, and when the eccentric sleeve rotates, a conical surface is drawn with the axis. Therefore, when the moving cone approaches the stationary cone, the ore is crushed. The casing consists of two parts, upper and lower, connected by bolts. A strong spring is installed on the bolt to prevent damage to the crusher (such as the spindle) when metal or other hard objects fall into the crushing chamber. If a metal block or other hard object (nut, drill head, etc.) enters the crushing chamber together with the ore, the stationary cone is lifted and the ore discharge port increases to discharge it.
