Stainless steel gear pump in the specific use of an important performance, in the design of a certain structure and performance, in accordance with certain methods of use and the principle of work and use of liquid transport can play a good advantage of features and performance, Here to introduce the composition and installation of stainless steel gear pump 1, composed of:
Stainless steel gear pump is mainly composed of pump, permanent magnet DC motor and the shell of three parts. Also equipped with safety valve and check valve.
Safety valve, also known as pressure limiting valve (or relief valve), is mainly composed of a valve seat, sealed steel ball and spring. Check valve installed in the stainless steel gear pump outlet. Pump body is the main electric gasoline pump, according to their different structures can be divided into: roller, turbo, gear and so on.
2, the installation location:
Stainless steel gear pump installation location there are two main types, namely installed in the fuel supply pipeline and installed in the fuel tank. However, the latter is widely used. The electric gasoline pump is usually suspended vertically in the fuel tank by a fuel pump bracket fixed on the fuel tank. Two-stage stainless steel gear pump need to pay attention to some issues and methods of use, due to the highly volatile gasoline, coupled with the pump when the temperature rise and suction when the local vacuum, so that the vaporization of gasoline, pump oil reduction, leading to output pressure fluctuation. Hyundai Motor in the widely used two-stage electric gasoline pump, that is, two electric gasoline pumps in series, so that oil supply capacity. When the pipeline is blocked or the fuel filter is clogged, the pressure of the gasoline exceeds the specified value, the pressure limiting valve opens and the gasoline flows back into the oil side. After the engine is turned off, the one-way valve is closed to prevent the reverse flow of gasoline in the oil pipeline and to maintain a certain residual pressure in the oil pipeline so as to restart the engine.

BQ supplys two types of Tower Crane Power Cable, YC Electric Power Cable and YCW Insulated Power Cable.
Power Cable is used for heavy industry including mining and marine, they must be robust and capable of handling both torsional and tensile stresses simultaneously. These mobile machines for lifting and handling are often manufactured with a robust rubber outer sheathing to protect against the constant reeling and movement as well as providing protection against oils and greases. Cables with Polyethylene (PUR) and PVC sheathing are also available. The cables are UV resistant – applications such as tower cranes and port loading gantries are subject to the elements – as well as being resistant to oils and greases.
The power cable used for a tower crane is typically a heavy-duty and high-voltage cable to handle the electrical power requirements of the crane. These cables are designed to be durable, flexible, and capable of withstanding harsh weather conditions. They are usually made of materials such as rubber or neoprene for insulation and protection against abrasion, oil, and chemicals. The exact specifications of the power cable may vary depending on the specific model and power requirements of the tower crane.
