Reasons For The Lower And Lower Construction Efficiency Of Mortar Spraying Machine

The use of mortar spraying machine in engineering construction has been very common, but long-term use of the equipment, especially on the basis of lack of maintenance, is easy to produce large or small problems. If it is not solved in time, it may not affect the progress of the project for a while, but if small problems are not solved for a long time, no matter how small problems will eventually cause bigger problems, it will be too late to regret it then. The reason for the lower and lower construction efficiency of mortar spraying machine?

1. Work speed slows down The slower operating speed of the mortar spraying machine is mainly due to the decrease of engine power and internal leakage of the hydraulic system due to the wear and tear of the whole machine. The hydraulic pump of the mortar spraying machine is a variable plunger pump. After a certain period of operation, the internal hydraulic components of the pump will inevitably produce excessive wear, which will cause internal leakage and inconsistent parameter data, resulting in insufficient flow and excessive oil temperature. The speed is slow. At this time, the mortar spraying machine needs to be overhauled, and the parts that are out of wear are repaired and replaced.

2. The solenoid valve does not work When the solenoid valve is controlled on the operation panel of the mortar spraying machine, the solenoid valve cannot be opened manually or automatically, and the solenoid valve coil or pilot valve or operation button can be replaced; the solenoid valve cannot be opened manually, and when the air outlet on the solenoid valve is exhausted, replace the solenoid valve ; Cannot be opened manually. When the lower outlet of the solenoid valve is exhausted, check whether the inside of the cylinder, seal ring, piston rod, compression screw, etc. leak.

3. Engine speed drops If the engine speed of the mortar spraying machine suddenly drops, first test the power of the mortar spraying engine itself. If the output power of the engine itself is lower than the rated power, it may be due to poor fuel quality, low fuel pressure, faulty brakes and their control levers, and turbines. Carbon deposits on the turbocharger. If the output power of the mortar spraying engine is normal, you need to check whether it is because the flow rate of the hydraulic pump does not match the output power of the engine. Such failures should start with the electrical system, then check the hydraulic system, and then check the mechanical transmission system. The daily maintenance of the mortar spraying machine is to prevent potential failures. Therefore, we must form the habit of maintaining equipment on time and regularly during daily use. So I tell everyone that when using the mortar spraying machine, we must pay attention to the inspection and maintenance of the mortar spraying machine.
