Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0020] figure 1 The structure of the mixed delivery pump with simplified functions of the present invention is shown. As shown in the figure, the present invention is realized in this way. A mixed delivery pump with simplified functions is an outer circulation fan plug shielding structure, and a pair of rotors 2 are installed vertically. Into the pump casing, the sealed volume is formed by the side end surface of the pump body 1 and the rotor 2. When the spur gear pair drives the rotor 2 to rotate in the opposite direction at the same angular velocity, the meshing line of the pair of rotors divid...

The invention discloses a numerically controlled mixed-transport pump with simplified functions. The numerically controlled mixed-transport pump with simplified functions has an outer circular flow fan plug shielding structure, a pair of rotors are vertically installed in the pump casing, and the side end surface of the pump body forms a seal with the rotor. volume. When the spur-toothed gear pair drives the rotor to rotate in the opposite direction at the same angular velocity, the meshing line of the pair of rotor parts divides the sealed volume into upper and lower parts. The upper inlet end of the pump body sucks in liquid, and engages through the lower side of the meshing line. This part of the volume is squeezed, and the liquid is discharged from the outlet port, and the trapped liquid flows away from the gap. The structural feature of the mixed pump with simplified functions of the present invention is that the motor directly drives the load as a whole, and the shaft does not extend to the outside. Therefore, there is no frictional shaft seal device during the operation of the pump, thereby preventing liquid leakage, including the driving part. Internally, no oil supply is required, and at the same flow rate, compared with other pumps, it is highly efficient and energy-saving.
Description
technical field [0001] The invention belongs to the field of fluid delivery machinery, in particular to a mixed delivery pump with simplified functions. Background technique [0002] Compared with similar foreign products, the various oil pumps used by my country's petroleum industry generally have disadvantages such as low efficiency, large energy consumption, and short life. In particular, the operating efficiency of various pumps is low. According to statistics, 60% of the pumps in the national oil fields and refineries are in unreasonable operating conditions. Low power factor etc. The valve throttling loss of some pumps accounts for 30-40% of the motor output. [0003] It is an inevitable trend in the development of energy-saving technology to adopt all-digital voice control technology to transform oil field pumps, which will greatly improve product performance, efficiency, controllability and reliability. As a combination of emerging high-performance strategies and ...
