Abstract

The invention discloses a method and system for controlling load viscosity and pumping equipment and relates to the technical field of engineering machines. According to the embodiment, a water feed pipeline is added to a conveying pipeline of a load, the actual pressure value of an oil pump oil outlet is then obtained in real time, the actual pressure value of the oil pump oil outlet is compared with a preset pressure value range of the oil pump oil outlet, output of a frequency converter is controlled according to the comparative result so that the water discharge of a water pump can be adjusted, and accordingly the load viscosity is controlled and the problem that the conveying pipeline is blocked due to excessively high viscosity of the load is further solved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a control method and control system for viscosity of a load, and pumping equipment. Background technique [0002] At present, industrial pumps, also known as piston sludge pumps, are widely used in sewage treatment plants. The sewage is processed into sludge through special processes: garbage classification, deodorization or dehydration, etc., and the sludge is pumped by industrial pumps to silos or dry incineration system. [0003] In the existing sludge pump workflow, refer to figure 1 , the dehydrated sludge reaches the buffer hopper; the sludge enters the double-screw feeder from the buffer hopper, and the sludge is sent to the material cylinder of the sludge pump through the double-screw feeder; the sludge passes through the pressure provided by the oil pump of the hydraulic station The sludge in the material tank is pumped out to the silo through the conveyi...
