In order to improve work efficiency and reduce machine wear, the YZH Pedestal Booms has been designed to handle two jaw crushers simultaneously. When there is a problem of material blockage and jamming in the crusher, the YZH Fixed Pedestal Rock Breaker Boom will promptly clear and crush the material. Even if it's two crushers, there's no need to worry. The YZH Fixed Pedestal Rock Breaker Boom adopts ultra long arms and small arms, which extend the rotation range and have a wider working range without the need for shutdown, indirectly increasing profits. For example, the YZH Pedestal Booms, which is used in conjunction with the Metso 6089 rotary crusher, has a working radius of up to 17 meters and is currently the largest YZH Fixed Pedestal Rock Breaker Boom in terms of working range. Its working environment is also very harsh, with a working temperature of up to 31 ℃ and a maximum temperature of up to 45 ℃, which requires extremely high performance and reliability of the equipment. YZH's ability to develop machines that operate in such harsh working environments is due to its adherence to the principle of not fearing hardship. In the crushing production line of the sand and gravel industry, commonly used crushing equipment includes jaw crushers, rotary crushers, and mobile crushers. It can be said that it is these devices that greatly improve the efficiency of sand and gravel crushing. There are pros and cons to something, and during the production process, there may also be situations where large blocks of sand and gravel block the feeding port, which can seriously affect the feeding situation. However, using a static fixed breaker boom system for secondary crushing can effectively promote the efficient operation of the sand and gravel production line.

AY type high temperature centrifugal oil pump is divided into six structures: single-stage single-suction cantilever type, two-stage single-suction cantilever type, single-stage single-suction cantilever type, single-stage double-suction double-support type, two-stage single-suction double-support type and two-stage single-suction double-support type. AY type high temperature centrifugal oil pump is especially suitable for conveying high temperature and flammable, explosive or toxic liquid. The installation method is horizontal center line support. The suction flange and outlet flange of the pump are cast on the pump body and are vertically upward. The bearing chamber (packing box) and the pump cover are cast into one, which can be used for packing seal, balanced type, flow type and series mechanical seal. An optional jacket of a water-cooled chamber is cast outside the shaft seal chamber. The water-cooled chamber shall be specially provided or provided when the conveying medium is water with a temperature exceeding 66 ° c and hydrocarbon action exceeding 150 ° c. Impeller for the whole casting, and through static balance check, the axial force of the pump mainly depends on the impeller balance hole to balance. The bearing body is equipped with a set of radial ball bearings and a set of thrust ball bearings mounted back to back. The bearings are lubricated with thin oil of oil swing ring. The external surface of the bearings is cast with heat sink, which can be cooled by air (T <120℃), fan cooling (T =120-260℃) and water cooling (T =260-420℃). Pump maintenance does not have to disassemble the suction or discharge pipeline. It is easy to disassemble the impeller, shaft, bearing, shaft seal and other parts. The shaft seal adopts mechanical seal. The pump is driven directly by a motor through a flexible diaphragm extension coupling. Viewed from the direction of the motor, the pump rotates counterclockwise.
