In recent years, the production technology of hydraulic pumps and related accessories for mixer trucks has been greatly improved, and many state-owned brands have mushroomed. However, its development is still limited, especially in the production of some core components, foreign brand technology still has a strong competitive advantage.
Mixer trucks can be divided into large and small mixer trucks according to the cargo volume, with 8 cubic meters as the dividing line. Currently, domestic hydraulic pumps and related hydraulic systems are mainly provided for small-sized mixer trucks, and eight cubic meters of mixer truck parts are provided. Mainly still import-oriented, if the three major pieces of domestic use, it may produce power can not keep up.
What should we choose when we buy? According to the number of hydraulic pumps, we can be divided into: single-link pumps (multi-purpose small mixers), double pumps (medium and small), multiple pumps (large), in the selection, usually purchased slightly larger than their size Yes, this will help maintain the completion of operations in special circumstances. It is not necessary to pursue large models and do a good job of lubrication. It is also provided according to its hydraulic pump. To provide the maximum working pressure to distinguish between, can be divided into the following four categories: Low-pressure pump (the maximum pressure is less than 7Mpa), used in the case of relatively small work intensity. Medium pressure pump (max pressure less than 32Mpa). High-pressure pump (the maximum pressure is less than 60Mp, these two types are used in more types of mixers. Ultra high-pressure pump (highest pressure is greater than 100Mpa) large amount of stirring, professional use of concrete mixers to use large-scale mixer. Of course, according to its use There are two kinds of quantitative pumps, variable pumps with different degrees of flexibility. In general, small-sized mixers mainly use fixed-displacement pumps, and large-scale or ultra-large-scale ones are usually equipped with variable displacement pumps to avoid material waste and hydraulic motor damage. The shape and structure of the hydraulic pump are selected. There are four types of structure of the gear pump, the vane pump, the screw pump and the plunger pump. Each of the four pumps has its own advantages. For example, the gear pump has relatively low requirements for oil, and is usually a low pressure system. It is mainly used in construction machinery and agricultural machinery.Although hydraulic variable processing is not available, it is cheaper to use.Plunger weight is mainly used in high pressure systems and engineering machinery applications. It is hydraulically more stable and high performance, variable characteristics make it The use of high cost, less used in private use.Spiral pump pollution resistance, but because of its hydraulic Small degree, its scope is relatively limited.
The above is a brief introduction on how to choose the mixer hydraulic pump problem, and hopes to help everyone.
