The cement quality directly affects the quality of architecture and the durability. And what’s more, it is the key link of the quality control of concrete batching plant. Clinker. As for the standard requirements, calcium metasilicate mineral accounts for no less than 66%, the quality ratio between the calcium oxide and silicon oxide is nor smaller than 2.0. But many cement factories only do the strength experiment frequently.Clinker content in the cement. In the standard requirements, the total content of ordinary silicate cement clinker and plaster should be not smaller than 80% and be smaller than 95%. But now, many large cement factories produce cement which contains only 65%-70% clinker, not alone many small cement factories all over our country. Generally, the cement in the small cement factories only contains 50% clinker. The small cement can not be called cement and it only can be called mixture.
Testing methods. Cement is in the supervision and administration of the Technical Supervision Bureau and the spot check is done every year, which can not restrain the production of cement factories. The necessary check items of national testing standard is only strength, setting time and safety, along with some chemical index, which is far from enough. What’s worse, some kinds of cement which have been taken some measures can satisfy these requirements easily.

The Structure Introduction of Haomei Concrete Pump
The important structure of concrete delivery pump is hydraulic pump. It can be divided into domestic hydraulic pump and imported hydraulic pump according to different origin. According to the different structure forms, hydraulic pump is composed of gear pump, vane pump and pillar-plug pump. Different forms of hydraulic pump can be used in different pressure grades.
Because of low cost and strong adaptability, gear pump is widely used in the trailer concrete pump manufacturers in the early time. However, because of the smaller pressure bearing and bigger impulse resistance, gear pump is often installed on the low pressure pump or used in the auxiliary oil passage system of medium and high pressure pump.Pillar-plug pump can be classified into oblique tray pillar-plug pump and oblique axle pillar-plug pump. It is very popular because of the wider adaptive pressure rang.
The main hydraulic pump of some low pressure concrete pumps adopts oblique tray pillar-plug pump, which improves the quality of the concrete pump for the high grade component configuration. The imported hydraulic pump is also oblique tray pillar-plug pump, which is world-class product. The domestic oblique axle pillar-plug pump is also high in quality. In fact, users can judge the quality of concrete pump performance from the grade of hydraulic pump.

Operating Procedures of Concrete Pump
Operating of Concrete Pump ,some matters needing attention in the pumping and maintenance of concrete pump.Operators can not maintain and repair the concrete pump until operators tuck the cantilever crane, cantilever crane has reliable supporting, the engine is shut down and outrigger legs are fixed.Before maintaining concrete pump, shut down the machine and release the pressure in the energy accumulator.If operators open the hydraulic lock of cantilever crane before fixing the relevant cantilever crane, it will produce some dangers of hurting people which are caused by the dropping of cantilever crane.Do not maintain and repair the concrete pump until the concrete pump is placed on the flat ground well and operators make sure that there is no unexpected move.
When the pipeline of concrete pump is blocked, operators must release the pressure in the concrete delivery pipeline by anti-pumping and then they can disassembly disassemble the concrete delivery pipeline.In the operation process of HBT80 trailer concrete pump, do not open the hopper mesh, cover plate of water tank and other safety protection facilities. It is prohibited to put your hands into the hopper and the water tank, or use hands to grasp other moving components.When pumping concrete, operators must make sure that the concrete in the hopper is on the pedal shaft in order to avoid the concrete jetting which is caused by inhaling gases.
