Network optimization data: when the pressure of high-pressure oil decreases and the pressure transmitted by the regulating spring to the pilot piston is greater than the hydraulic pressure at the upper end of the pilot piston, the control valve core moves above the valve sleeve under the action of the regulating spring to connect the control oil in the large chamber of the variable piston with the low-pressure chamber. The pressure at the small end of the variable piston is high and the pressure at the large end is low, so the variable piston moves downward under the effect of pressure difference

BMR cycloidal motor: equipment advantages/The product characteristics BMR series cycloidal oil motor is a kind of shaft flow distribution oil motor. The motor of this series uses a cylindrical rotor stator pair, which has the structure of running under high working pressure and self compensation, so that the whole equipment has high efficiency, good maintenance and long service life. Its advantages: 1

Network optimization data: when port A does not supply oil, the balance valve returns to the middle position. Due to the inertia of the machine, the motor continues to rotate, and the motor becomes a pump. The hydraulic motor company caused the pressure at port B to rise due to the closing of the balance valve, and the pressure oil of the high-pressure hydraulic motor entered the buffer chamber through the orifice in the middle of the left safety valve, pushing the buffer piston to move to the right, while opening the left safety valve to move to chamber A

Network optimization data: hydraulic motors have many performance parameters. The following are the main performance parameters of the hydraulic motor: 1. The displacement, flow and volumetric efficiency usually refer to the volume of liquid to be entered according to the geometric size of the motor shaft every week, which is also called the volume of the motor, V. The five star hydraulic motor is sometimes called the geometric volume, which theoretically means that the volume is not considered in case of leakage.

Network optimization information: gear hydraulic motor. The gear type hydraulic motor is also divided into external gear type hydraulic motor and internal gear type hydraulic motor. Gearbox motor has the advantages of small size, light weight, strong self-priming capacity and easy maintenance. However, the gear motor has many shortcomings, such as large pressure and flow pulsation, low volume efficiency, low input pressure, small output torque, and high noise

Network optimization data: When a high-rise building is on fire, the most urgent and important problem is to rescue the residents on the high-rise building from the building on fire as soon as possible. At this time, if there is a long soft belt that people can step on and slide to the ground, it is undoubtedly a good solution. However, what kind of curve can this long soft belt turn into so that people can escape from the fire as quickly as possible? That's the question of the fastest route
