As an important equipment in road construction and maintenance, the performance of road marking machine directly affects the quality and efficiency of marking. Its core working principle relies on the engine-driven high-pressure pump to realize the airless spraying function. However, when encountering a situation where the pressure does not come up or is unstable, the machine will not work properly. The following is an in-depth analysis of the road marking machine pressure instability and the corresponding solution.
First, the road marking machine pressure instability reasons
Hydraulic oil is insufficient or poor quality: hydraulic oil is the road marking machine hydraulic system is an important medium, its quantity and quality of stability is directly related to the stability of the pressure output. Insufficient or deteriorated hydraulic oil will cause the hydraulic system to work abnormally, which in turn affects the pressure stability. Therefore, the amount and quality of hydraulic oil should be checked regularly, supplemented and replaced in time to ensure that the quality and quantity of hydraulic oil are up to standard.
Loose or leaking suction pipe: the suction pipe, as a key component connecting the scribing machine and the paint storage tank, its sealing is crucial. Once the suction pipe is loose or leaking, it will directly affect the efficiency of paint inhalation, thus leading to unstable pressure. To address this issue, the connection of the suction pipe should be carefully checked to ensure good sealing, and the leakage point should be repaired or replaced in time.
Insufficient paint volume: Paint volume is another important factor affecting the pressure stability of the marking machine. Insufficient amount of paint will lead to insufficient supply of paint during the spraying process, thus affecting the pressure stability. Therefore, before construction, you should fully understand the construction situation, prepare enough paint materials, and pay attention to adding paint in time during the construction process to avoid insufficient paint leading to poor spraying results.
Unreasonable gap of suction valve: The size of the gap of the suction valve directly affects the suction efficiency and pressure stability of the paint. Too small a gap may lead to insufficient suction and unstable pressure; too large a gap will cause paint leakage, also affecting pressure stability. Therefore, the suction valve gap should be checked and adjusted regularly to ensure that it remains within a reasonable range (generally recommended to be 2 to 4 mm).
Low winter temperatures lead to high paint viscosity: Low winter temperatures increase the viscosity of the paint and reduce its fluidity, making it difficult to suck in the paint. This not only affects the pressure stability of the scribing machine, but also reduces the scribing quality. For this problem, the following measures can be taken: first, use the mixer to stir the paint fully to improve its fluidity; second, add the appropriate amount of thinner to reduce the viscosity, but need to pay attention to the proportion of thinner, so as not to affect the effect of marking.
Second, optimization strategies and recommendations
Strengthen routine maintenance: regular maintenance and repair of road marking machine, including checking hydraulic oil, cleaning and replacing filters, checking the suction pipe and suction valve, etc., to ensure that the equipment is in the best working condition.
Professional training and guidance: Provide professional training to operators to improve their equipment operation skills and maintenance awareness. At the same time, we provide detailed instruction manuals for the use and maintenance of the equipment so that the operators can consult them at any time.
Selection of high-quality accessories: When purchasing road marking machine and its accessories, we should pay attention to the quality and select high-quality and reliable accessories to improve the overall performance and stability of the equipment.
Establishment of failure warning mechanism: through the installation of sensors and monitoring systems, real-time monitoring of the working status of the equipment and pressure changes, timely detection and early warning of potential failures, so that timely measures can be taken to deal with them.
Road marking machine pressure is insufficient, often stemming from these core issues. By strengthening routine maintenance, professional training and guidance, the use of high-quality parts and the establishment of a failure warning mechanism and other measures, you can effectively improve the stability and reliability of the road marking machine, to ensure the quality and efficiency of marking.
