Marking Machine DE-18A

Marking Machine DE-18A - a modification of the upgraded machines DE-18, which differs from that discussed above: 1) the presence of an additional engine D-21A for the drive (installed on the machine DE-18), a compressor-type PC-1, 75 m 2) construction of tanks for ink capacity of 500 liters each with pneumatic actuators blade agitators.

Labelling machine EH-40, designed for mechanical application of the safety line on the carriageway of streets and roads, is based on the UAZ-452D. Operating consists of a working body, two tanks with paint, remote control, to guide the viewer's machine during the operation: Rack enclosure and accessories.

By car, the ED-40 produced a basic revision of the UAZ-452D: removed from the vehicle cabin and its direction of motion reversed, the rear axle is replaced by a special drive axle and the front - has become the leading and rear driven axle, and in transmission between the clutch and transmission installed creeper, also provides the drive plunger pump spray system changed

linking mechanisms to control the machine, the steering column, on both sides of the front car is equipped with two tanks with a capacity of 600 liters paint, which can mark up without charging extra 20-30 km of the road, behind the machine is equipped with accommodation for the workers and the storage rack enclosure. The system consists of a coating machine and the booster pump plunger, separating chamber with a valve box, a receiver with a safety cap a fine filter spray gun, the receiver filter-pump, tank and spray gun to paint a high-pressure type KRVD-10.

During operation, the motion of the plunger pump up the volume of oil contained between the plunger and the separation capacity of the pump (usually an aqueous solution of cadmium sulfate, acts through the fluid on the paint, pushing it through the check valve valve box to the receiver, and hence it is under pressure, determined adjusting the pressure relief valve, passes through a fine filter to the spray gun. during the return plunger pump creates a vacuum and paint from the tank passes through the filter and check valve in the valve box separating chamber.
