1, The design of the power part of the one-piece cold pipe bender is relatively narrow. During the maintenance of the engine, the removal of oil filter and diesel filter is complicated due to the small gap between various parts. The independent power station is very convenient in daily maintenance because of the large gap between different parts.
2, In order to give the operator a low noise working environment, the power part is designed as an independent type, which can be far away from the main engine, and the fast connection device is used to connect with the main engine. Meanwhile, it is convenient for cold pipe bending machine transportation.
3, The operating temperature of the hydraulic oil circuit of pipe bender equipment is between -30 ºC and 50ºC. The high temperature construction environment has brought inconvenience to the long time construction of the cold bending pipe, which is easy to cause high oil temperature rise and accelerated aging of hydraulic components, which has seriously affected the service life of the equipment. The radiator of the power source must have sufficient heat dissipation capacity. Therefore, the design of a special radiator device, heat dissipation effect is two times of the ordinary radiator, and installed a temperature sensor, the realization of automatic temperature control. Ensure that the cold pipe bender can run for a long time without stopping. Improved work efficiency.
4, Hydraulic oil preheating device is added
During the construction of the cold pipe bender in the low-temperature environment, due to the low temperature of the hydraulic oil, the preheating circulation system is formed by using the radiator of the engine, so that the temperature of the hydraulic oil rises rapidly, the preheating time of the equipment is increased, and the equipment enters the working state in advance.
5, The oil suction filter and oil return filter are installed on the hydraulic mailbox of power station, and the warning device for cleaning and replacing the filter element of hydraulic oil filter is installed. Can prompt the operator to carry out maintenance work in time.
