Plunger pump type spraying machine suitable for large engineering

Abstract

The invention discloses a plunger pump type spraying machine suitable for large engineering. The plunger pump type spraying coater comprises a supporting seat plate and a movable push rod, a material storage box and a mounting seat are fixedly mounted on the top surface of the supporting seat plate, a buffer mounting seat is fixedly mounted on the inner side of the movable push rod, and a plunger pump is fixedly mounted on one side of the buffer mounting seat; the outer side of a spraying pipe is movably sleeved with a corrugated pipe sleeve, the end of the spraying pipe is fixedly connected with a spray head fixing mechanism, and the spray head fixing mechanism comprises a movable sleeve head, a static spray head and a piston ring. According to the plunger pump type spraying machine suitable for large engineering, by arranging a buffering mechanism, transverse impact and vibration generated by reciprocating motion of the plunger pump are relieved through a buffering mounting base and a damping vertical frame, high-frequency vibration of the spraying machine in the using process is prevented, the situation that a control system goes wrong due to the influence of equipment vibration and reciprocating motion is avoided, and the spraying construction efficiency is improved; the method is suitable for long-term operation of large-scale projects.

Description

technical field [0001] The invention relates to the technical field of spraying machines, more specifically, the invention is a plunger pump type spraying machine suitable for large projects. Background technique [0002] The main working parts of the spraying machine are diaphragm pump type and plunger pump type booster pump. The reversing mechanism is a special pilot-operated full air control air distribution reversing device. After entering the compressed air, the piston moves to the upper or lower end of the cylinder. At the same time, the upper pilot valve or the lower pilot valve is activated, and the air flow is controlled to instantly push the air distribution reversing device to change direction, so that the piston of the air motor makes a stable and continuous reciprocating movement. The traditional room temperature spraying machine uses a diaphragm pump and a plunger. Pump type, the working principle of the diaphragm pump determines its short working life and high...

Problems solved by technology

[0002] The main working parts of the spraying machine are diaphragm pump type and plunger pump type booster pump. The reversing mechanism is a special pilot-operated full air control air distribution reversing device. After entering the compressed air, the piston moves to the upper or lower end of the cylinder. At the same time, the upper pilot valve or the lower pilot valve is activated, and the air flow is controlled to instantly push the air distribution reversing device to change direction, so that the piston of the air motor makes a stable and continuous reciprocating movement. The traditional room temperature spraying machine uses a diaphragm pump and a plunger. Pump type, the working principle of the diaphragm pump determines its short working life and high failure rate; the plunger pump type marking sprayer, so the marking industry mostly adopts the diaphragm pump type which has been eliminated by the plunger pump type sprayer

[0003] The reaction force to control its reciprocating motion is large. At this time, it is necessary to add a buffer mechanism and other reaction force elimination mechanisms to the overall equipment, and use the buffer unit to eliminate the reciprocating force of the plunger pump. The traditional spraying machine does not use a buffer mechanism. , resulting in inconvenient operation for personnel during spraying, and the reaction force is easy to push the overall movement of the spraying machine, resulting in spraying deviation. Long-term hand-holding is not suitable for long-term operation of large-scale projects. Due to the influence of equipment vibration and external signals, the control system is prone to problems. Seriously affected the efficiency of spraying construction
