How to properly install the use of grinding fluid pump?

    Sand pump installation:

1, the installation of the base: a, the sand pump and the pumping source can be installed near the best to shorten the length of the suction section, reducing the loss during inhalation; b, self-absorption of the sand pump is poor, the pump must be installed below the pumping source level ; C, when installing the chassis all the basic requirements are level, solid and reliable, in order to avoid machine vibration.

2, the coupling installation: Couplings must be concentric with the shaft, the installation of the two axes must be aligned, the error requirements: parallelism offset ≤ 0.25, the axis angle error ≤ 0.12.

3, into the export pipeline installation:

3.1, the installation of imported pipelines: a, the inlet pipe cross-sectional area must be greater than or equal to the pump flow cross-sectional area and the pipeline at the entrance of the sand pump must be straight, the length of the suction pipe diameter of at least twice. ; B, in order to avoid bubbles in the suction pipe, pumping source and the pump should gradually transition from high to low. c, the use of the hose as a suction pipe, you must ensure that the hose is not compressed so as to reduce the flow rate or even cut off.

3.2, the export pipeline installation: a, in order to facilitate the pump maintenance, the export pipeline should be installed normally open valve; b, all the pipeline (including the inlet pipeline) must have its own support must not be allowed to pump Road weight; d, when the working conditions are unknown or unstable, the outlet pipe must be installed in the throttle valve to ensure that the pump at the design point of operation; e, when the pump outlet and pressure equipment connected to the throttle and the pump A check valve must be fitted between the outlets to prevent backflow of the liquid, otherwise the backflow will cause loosening of the impeller causing mechanical damage to the pump and leakage of fluid from the sleeve.

    Use of sand pump :

1, the use of sand pumps should be used within the design of the sand pump;

2, packing seal can not be too tight, we must ensure that there is a certain amount of leakage for lubrication;

3, must be in accordance with the provisions of mechanical seal maintenance;

4, when the pump should be released after pumping excess liquid pump, and rinse with water to prevent the next start impeller blockage, torque, resulting in shaft fracture.

Our robots used to match all processing machines to realize fully or semi Automatic Production Line for stainless steel hardware, such as dish, bowl, cup, pot, pan, cover, basin etc.. The production quality is stable and best due the steel products can soak drawing-liquid or paste oil to obtain the protection for the drawing tension of stainless steel in the processing and shape perfect. Also it can be annealed for better result for quality and shape. And the groove and diameter changing of products can be safely done by the automatic feeding and discharging from the beader and trimmer.
