CONCRETE PUMP AND METHOD OF CONTROL OVER CONCRETE PUMP SWINGING DRIVE |
摘要 |
FIELD: engines and pumps.SUBSTANCE: invention relates to concrete pump and to control over pressure of concrete pump swinging drive. Concrete pump comprises oscillatory drive and S-like distribution valve 17. Note here that said oscillatory drive is actuated by hydraulic swinging circuit to control said S-like distribution valve. hydraulic swinging circuit comprises swinging drive pressure F control module that effects control over said pressure in compliance with first pressure F1 and/or second pressure F2 where F1 is hydraulic oil pressure in hydraulic circuit of mixing while F2 is oil hydraulic pressure in hydraulic circuit of concrete feed cylinders.EFFECT: prevented overpressure or unreasonably low pressure applied to S-like distribution valve, hence, high-rate shock and noise, inertial impact and vibration of the housing.11 cl, 5 dwg |
