The Main Reasons and Solutions for Pressure Loss of Hydraulic Systemworking Pump on the Rebar Rolling Mill
Abstract
The hydraulic system of a rebar rolling mill is the power source of the mill, and the pressure loss of the hydraulic system working pump will affect the operation of the mill. This paper mainly introduces the main reasons and solutions for the pump pressure loss.
Keywords: Rebar Rolling Mill; Hydraulic System; pressure loss
Introduction
The hydraulic system of a rebar rolling mill is the power source of the mill, and the pump is the driving force of the system. The pressure loss of the main pump will affect the operation of the mill and the production of the mill. Excessive pressure loss will cause some components of the system to fail. The pressure loss of the main pump is mainly caused by the following reasons.
Reason one： Due to the wear of the pump itself and the piping of the system, the cross-sectional area of the pipeline will change. This will cause the flow rate of the pump to decrease and the pressure loss to increase.
Reason two： Some components of the system are blocked by foreign objects or the seals are not used well, resulting in pressure loss of the pump.
Reason three：The oil pump is installed in an inclined way, and viscosity of the oil is too large, resulting in pressure loss of the pump.
Reason four：The plunger and sleeve are worn out, which causes the inner leakage of the pump to be large, resulting in pressure loss of the pump.
Reason five：The pressure setting of the safety valve is too large or the safety valve is too small, resulting in pressure loss of the pump.
Solution
Solution one：Regularly check the pipelines of the system and replace them if they are worn out.
Solution two：Clean the system regularly and ensure good sealing of all parts.
Solution three：The oil pump should be installed flatly, and appropriate oil should be selected according to the service environment.
Solution four：Regularly check and replace the plunger and sleeve of the pump if they are worn out.
Solution five：Adjust the pressure setting of the safety valve and select the safety valve according to the actual situation.
Conclusion
The pressure loss of the hydraulic system working pump of a rebar rolling mill will affect its operation. The main reasons for the pressure loss are the wear of the pump itself and the piping of the system, the blockage of some components, the installation of the oil pump in an inclined way, the wear of the plunger and sleeve, and the pressure setting of the safety valve. Regular maintenance and regular checking of the system are the solutions for the pressure loss problem.
