Aluminum alloy materials are widely used in all walks of life due to their low density, high strength and stiffness, good corrosion resistance, and good processing performance. At present, the proportion of aluminum alloy forging in the aluminum alloy industry is still relatively small. Due to the relatively high cost of aluminum alloy forging, the production technology is relatively difficult, and most of them are used in parts that are particularly important in stress. However, with the rapid development of the aerospace and automotive industries, the demand for aluminum alloy forgings is increasing day by day. In particular, the forgings on the aircraft account for a large proportion, mainly aluminum alloy forgings, because the aircraft has relatively high requirements for strength and weight. There is also an increasing demand for aluminum forgings in the automotive industry. Therefore, our future task is how to improve and improve the aluminum alloy forging technology to meet the increasing demands of the aluminum forging industry.
Aluminum alloy forging is relatively easy in the forging industry, and SCZY can easily deal with steel forgings, so under the condition of reasonable product structure, we can fully handle the production and service of aluminum forgings.

Install a large baseless pump, the first poured cement base has been cleaned, the pump hoisted to the base, then set into the anchor bolts, and then according to the following methods and steps for installation.
1. The pump to find the purpose of the pump to find is to make the import and export of the pump center line and the axis of the pump concrete base pouring the corresponding center line is fully consistent with the power machine to match. The correct way is to: Aspect to the vertical and horizontal centerline, in the air each pull a vertical and horizontal centerline perpendicular to each other, hanging in the two lines on each of the two, move the pump to import and export of the centerline and axis hanging Line coincidence.
In the process of finding a job, if it is found that the anchor bolt is not correct, or the pump itself does not meet the requirements of the bolt hole manufacturing instructions on the drawings, bolt holes and bolts do not match, or on the back of no room for movement, which Must take appropriate measures, such as expanding the pump anchor hole, knocking bolt, so that the pump to find the error does not exceed the required value.
Cantilever single-stage single-suction centrifugal pump to find the same time by the above method to find the positive axis can be, should pay attention to the pump outlet center to meet the design of the outlet pipe installation place ?.
2. To find the level to find the level of the purpose is to make the pump shaft to be level, the pump inlet and outlet flange surface was vertical to ensure that the inlet and outlet connections are correct. Pump leveling commonly used in the following ways:
(1) When leveling the small centrifugal pump, lean the horizontal foot against the flange of the pump inlet and outlet and the end face of the backrest wheel at the shaft end. Adjust the level of the water pump with a wedge-shaped iron block to center the bubbles of the level ruler.
(2) large and medium-sized sh-type pump, you can lift the pump cover, the pump seat and the pump cover the junction of the election four "+" -shaped point, standing water ruler, If the four point scale readings are equal, indicating that the pump is level. If the error of the four directions of error exceeds 0.3mm / m ~ 0.5mm / m, indicating that the level exceeds the specified value, the application of wedge iron adjustment until it meets the requirements.
3.Measurement High pump elevation is the elevation of the pump shaft centerline. The purpose of the test height is to check the actual installation of the pump height and design of the installation height is consistent with the pump to ensure that the water within the allowable height of work. The method of measuring the height of a marker uses two rods, one on the base surface of the target and the other on the base of the center line of the pump shaft, calibrated with a level gauge, and the actual height of the installation is found after calculation. The above correction, to find equal processes, are often interdependent, so it needs several repeated adjustments until it meets the requirements. After the location of the pump will be fastened to complete the installation of the pump body fasteners. 
At present, there are two kinds of products of centrifugal pump with base and no base. Install a small pump with a base, the first base on the base hanging, put on the ground screw, adjust the base position, and then use the level of the base on the processing surface, check?

Horn must be stable, the number of each pile of horn does not exceed 3, in order to avoid sliding or bouncing phenomenon. After the tightening of the ground screw, the level of the screw should be checked again. If it meets the requirements, the cement mortar can be used to fill in the bottom of the stand for secondary grouting. After the cement mortar is solidified, the water pump should be installed.
