Embodiment Construction

[0029] The present invention will be described below in conjunction with the accompanying drawings and specific embodiments.

[0030] The invention provides "a two-drive cutting device based on hydraulic energy recovery". It uses the residual energy of the hydraulic oil when the hydraulic system returns oil to drive the rotor to rotate and cut, effectively realizes hydraulic oil cooling and energy recovery, and uses the rotary cutting device to solve the problem of debris winding, while the pump shaft drive mode is different under different requirements. effective supplement.

[0031] A two-drive cutting device based on hydraulic energy recovery, the device is installed in the middle of the water inlet and the impeller, including water inlet trumpet 1, skeleton oil seal 2, deep groove ball bearing 3, rotor impeller 4, rubber sealing ring 5, Oil chamber upper cover 6, bearing cover 7, moving knife head 8, static knife holder 9, oil inlet pipe 10 and oil outlet pipe 11; water i...

Abstract

The invention relates to a two-wheel drive cutting device based on hydraulic energy recovery. The two-wheel drive cutting device mainly comprises a water inlet flare tube, a framework oil seal, deep groove ball bearings, inner hexagonal bolts, rotor impellers, outer hexagon bolts, rubber sealing rings, upper oil cavity covers, bearing caps, a moving cutting head, a static tool rest, an oil inlet tube, an oil outlet tube and a pump shaft. The moving cutting head arranged on the device is driven to rotate by waste energy of hydraulic oil and constitutes a cutting pair with the static tool rest,and cutting for sundries is realized. When the hydraulic oil is not used, the device can be driven by connection with the pump shaft through keys. The whole device is located at a water inlet and is arranged underwater during running, and cooling for the hydraulic oil is realized. The device can be widely applied to a hydraulic driven pump station, and purposes of energy conservation and emissionreduction are achieved while problems of the hydraulic pump station are solved.

Description

technical field [0001] The invention relates to an anti-winding cutting device of a hydraulic mixed flow pump, in particular to a two-drive cutting device based on hydraulic energy recovery. Background technique [0002] The hydraulic mixed flow pump uses the hydraulic system to supply oil to realize the operation of the hydraulic motor driven hydraulic pump. It is small in size and portable, and is widely used in various mobile pump stations. However, the temperature of the hydraulic oil in the hydraulic system will exceed the standard when it circulates, which will affect the performance of the system, so it is necessary for the cooling of the hydraulic oil. Secondly, in the hydraulic system, when the hydraulic oil is recovered, there is often a lot of hydraulic energy remaining, which cannot be effectively used, and is completely lost after entering the oil tank, resulting in a waste of energy. [0003] The application occasions of hydraulic mixed flow pumps are not limi...
