1, in the use of the paving machine, how to do a good job in the maintenance of hydraulic system?
Answer: in the use of the paving machine, do a good job in the maintenance of hydraulic system, you can greatly reduce the fault. General should pay attention to the following points:
(1) hydraulic oil in hydraulic tank joined the former, should use clean containers of oil, hydraulic oil must be after oil filter filter, then add the hydraulic oil tank; the replacement cycle of the hydraulic oil as the oil quality and (1000h changed once; replacement of hydraulic oil should be in the working temperature; in order to ensure good heat dissipation of the hydraulic system, should also regularly clean hydraulic oil radiator.
(2) due to the asphalt paving machine construction environment is generally relatively poor, hydraulic oil filter replacement cycle should also be shortened (generally was750h is appropriate), replacing with a new filter element, when should be checked, prohibited the use of deformed, pollution or rusty filter.
(3) in the daily start of the engine work, should be idle for some time after the operation, and then to control the implementation of components, so that the use of hydraulic pump.
(4) due to the long-term use, the hydraulic system parameters will change, therefore, should be regularly check the hydraulic system parameter settings, to be adjusted in time.
Q: how is the guide wheel working?
Answer: guide wheel parallelism is a traction sheave elevator car center point and the guide wheel of heavy center line should be with bearing beam, a guide wheel, a guide wheel positioning datum line in the vertical direction superposition, and on both sides of the guide wheel surface should be parallel with the baseline.
Q: is the feature of the Guide wheel?
Answer: a guide wheel, its characteristic is which is composed of a sleeve, a regulating screw, casters, a pedestal, a steering pin seat and composition, is sheathed in the sleeve with adjusting screw, regulating screw at one end of the handle is installed, on the other end of the frame connected by adjusting screw nut and the caster, castor rack and castors connection; turning seat connected with the base through a pin, base and steering seat are respectively provided with the same center distance corresponding to the holes, U-shaped pin in order to insert to turn a corresponding hole of a seat and a base, a U-shaped bolt the base is fixed on the trailer of the rectangular pipe.
Unit pump refers to a cylinder of an oil pump, the oil pump here refers to the high-pressure pump, or as a fuel injection pump. The whole pump means that all cylinders share a high pressure oil pump. Unit pump body and the pump overall than done relatively large, such as high power diesel engine are generally single pump, in addition unit pump if damage to the oil pump only needs to replace a pump without the need to like the whole pump that all replacement and lower cost.
