Stainless steel gear pump features are as follows: First, stainless steel gear pump continuous operation for a long time. Stainless steel gear pump pump and motor coaxial, short shafts, rotating parts light weight, so the bearing to accept the load (radial) is relatively small, longer life expectancy than the ordinary pump. Second, stainless steel gear pump does not exist cavitation damage and irrigation water and other issues. Especially after the point to the operator brought a lot of convenience. But everything is split in two, the most critical issue with stainless steel gear pumps is usability issues, as stainless steel pumps are used under liquid conditions; the mediums to be delivered are mixed liquids containing solid materials; the pumps The motor is very close; the pump is vertically arranged, the weight of the rotating part is in the same direction as the impeller receiving water pressure. These problems make stainless steel gear pump in the seal, the motor bearing capacity, bearing arrangement and selection of the request is higher than the average sewage pump. Third, stainless steel gear pump compact structure, small footprint. The stainless steel pump can be directly installed in the sump due to its submerged operation. It is not necessary to build a special pump room to install the pump and machine, thus saving a lot of land and construction costs. Fourth, stainless steel pump repair convenience. Small stainless steel gear pump can be free devices, large stainless steel gear pump usually equipped with automatic coupling installation can stop automatic device, installation and maintenance quite convenient. Fifth, the stainless steel gear pump pump has a well-designed drain and return tank, the gear in the work to withstand the torque of the smallest, so the bearing load, wear a small, high pump efficiency.
Fiberglass Pipe Wrap Tissue is used as excellent substrate for anticorrosion wrapping on steel pipelines buried underground. It is characterized as high tensile strength, good flexibility, uniform thickness, solvent resistance, moisture resistance and flame retardent. It is well compatible with impregnating bitumen and coal tar enamel. The pipelines wrapped by fiberglass pipe wrapping tissue can widely improve capabilities against leakage and aggressive media in the environment and the cost for maintenance can be minimized significantly, so it is the excellent substrate for oil or gas pipes.
