Purpose of pump 503

The rotary vane vacuum pump KO-503 is designed to create a vacuum or excess pressure in the tanks of vacuum MV machines at ambient temperatures from -20 to +40°C. TU 3648-002-50341404-05. Using the vacuum created by a vacuum pump, the tank is filled and emptied.

The pump is equipped with a KO-503 lubrication system for forced lubrication of the pump. When operating the pump, it is important to correctly adjust the oil supply: 12 drops per dropper per minute.

The KO-503 vacuum pump consists of a ribbed cast-iron body, closed on both sides with covers. Inside the housing there is a rotor that rotates on two bearings. Textolite blades (technical plates) are installed in the rotor grooves.

Equipment with pump KO-503: Vacuum machines on GAZ chassis

Application

Do you need to create a vacuum or excess pressure in the tanks? In this case, we recommend buying a vacuum pump for the KO-503 sewer truck. The left-hand rotation model is mounted on the GAZ 3307. A modification of the right-hand rotation pump is suitable for the GAZ 3309. In addition, this vacuum pump is also suitable for the GAZ 53.

The left direction of rotation of the rotor shaft is suitable for cars with diesel and carburetor engines equipped with ABS. The right one is suitable for cars with diesel engines, without an anti-lock braking system.

Sludge and vacuum equipment do an excellent job of cleaning septic tanks, wells, cesspools, sedimentation tanks, pipeline elements, sewer and stormwater systems. Similar municipal equipment allows you to free space from accumulated silt or oil sludge. A modern sludge suction device washes away sediment by connecting the necessary devices to the operation.

Design features:

The basis of the special sludge sucking machine is hydraulics, a pneumatic hydraulic system, a pump and a metal tank. In addition to the listed components, the design of the unit must include additional electrical equipment. Despite all its reliability, such equipment is prone to breakdowns during operation due to physical wear of spare parts or exposure to external factors.

the pump that fails - it experiences constant mechanical and electrical pressure, so malfunctions during movement are almost inevitable.

The rotary vane hydraulic pump operates in conjunction with other hydraulic equipment designed in the design. The hydraulic pump housing ensures that wastewater and sewage are pumped into a special canister for subsequent transportation to the disposal site. In a short period of time, the KO series pump creates the required vacuum in the puncture chamber. As soon as it reaches a certain value, the pumped debris will begin to flow into the storage tank.

Individual sets that are part of more complex mechanisms: gears, sleeves . A special equipment safety valve is responsible for maintaining a given vacuum pressure force inside the tank . If in good condition, it blocks the so-called suction hole provided on the vacuum line as soon as the machine’s container is filled. In most units, the safety valve is installed in the cover.

An equally important detail is considered to be a hydraulic hose , which is connected to the receiving hatch using a union nut, fits tightly onto the hose sleeve and is firmly fixed.

The receiving entrance, made of a small hatch, is located on the rear side of the tank on the flange. It looks like a gate or valve and serves as a connecting element between the tank and the hose. These parts act as the basic unit of the suction line.

Comparison of vacuum pumps for various municipal vehicles

The vacuum pump is designed to create a vacuum in the tank of vacuum and sludge sucking machines. It consists of a cast iron housing in which the rotor is eccentrically mounted on bearings. Textolite blades move freely in the grooves in the rotor. When the rotor rotates, the blades, due to centrifugal force, are pressed against the inner surface of the pump housing. Air is pumped due to changes in the volumes of cells formed by an eccentrically located rotor, textolite plates, pump housing and end covers. The pump is equipped with a lubrication system. Lubricant flows to the bearings and into the suction cavity of the pump. The amount of supplied oil is regulated by adjusting screws. For long-term operation of the vacuum pump, it is necessary to keep the pump clean, prevent the housing from heating above 80°C, monitor the oil consumption of the lubrication system (oil consumption should be 12 drops per minute with each dropper (120 g/hour with all droppers), periodically flush the oil tank and fill it with clean filtered oil K-12 GOST 10877-76.

Vacuum machines use pumps KO-503V.02.14.100, KO-505A.02.15.100, KO-522A.02.01.100, KO-510.02.16.000.
