First, the advantages of hydraulic pump hydraulic transmission:
ATUS
01 Small size, light weight, so the inertia force is small, when suddenly overloaded or stopped, there will be no big impact; 02 can automatically adjust the traction speed smoothly within the given range, and can achieve stepless speed regulation; 03 Commutation is easy, without changing the direction of rotation of the motor, it can be more convenient to realize the rotation of the working mechanism and the conversion of linear reciprocating motion; 04 The hydraulic pump and the hydraulic motor are connected by tubing, and the space arrangement is not strictly limited to each other; 05 Because the oil is used as the working medium, the relative moving surface of the component can be lubricated by itself, with small wear and long service life; 06 Simple operation and control, high degree of automation; 07 Easy overload protection.
Second, the shortcomings of hydraulic oil pump hydraulic transmission:
ATUS
01 The use of hydraulic transmission has high maintenance requirements, and the working oil should always be clean; 02 The manufacturing precision of hydraulic components is high, the process is complex, and the cost is high; 03 Hydraulic components maintenance is more complex, and need to have a higher level of technology; 04 Oil as the working medium, there is a fire hazard on the working face; 05 Low transmission efficiency;
