Vacuum pump KO 503 for a sewage disposal machine: technical characteristics

Vacuum pump for sewer truck

contents
To clean cesspools in an autonomous sewer system or remove blockages in centralized systems, a sewer truck is used. This technique helps keep communications in working order and in accordance with sanitary and hygienic requirements. The main working element is the vacuum pump for the sewer truck. It operates on the principles of differential pressure. Using the properties of a vacuum, it pumps out the contents of the sewer.

Pump in a sewer truck

During the process, the pump does not interact with liquids; they pass through the hose. The system operates under heavy loads, so the sewer tank is made of durable, mechanically resistant materials. There are many types of pumps, mainly they differ in their ability to work with liquids of different degrees of contamination. But before you start pumping using any of the models, you must first prepare the environment, since a sudden creation of vacuum pressure can cause the device to malfunction. The sewer truck consists of the following modules:

• tank for collecting and transporting sewer liquids;
• Vacuum pump;
• a device that controls the filling of the tank;
• hose tap;
• hatch and hose for receiving waste.

Scope of application of pumps

A sewer truck is a vehicle equipped with an installation for pumping liquid from sewers, mainly based on domestic trucks. A tank is installed on the car into which waste is pumped. Inside there is a vacuum pump for a GAZ, KAMAZ, ZIL or URAL sewer truck. Special equipment is used to solve the following tasks:

• pumping waste from cesspools;
• clearing clogged sewer lines;
• pumping out liquid for access to the repair area of ​​engineering systems;
• flushing of pipelines for various purposes.

The process of pumping waste using a sewer truck

This special equipment is capable of operating in a wide temperature range: from -20 to +40 degrees C. The machines are used by housing and communal services and private enterprises providing specialized services. More often than other models, a vacuum pump is used for the GAZ 53, GAZ 3309 and GAZ 3307 sewer trucks.

Types of vacuum pumps

Two classifications apply to devices. According to their design, vacuum pumps for sewer trucks are divided into the following types:

• steam oil pumps use oil;
• membrane models operate on the principle of compressed air energy;
• water ring devices use water;
• The rotary vane type operates using retractable vanes.

The pump for the GAZ, URAL and other models of sewer trucks are also classified according to the parameters of the pressure created:

• booster pumps pump out liquids at high speed, balancing incoming and outgoing pressure, installed between the fore-vacuum and high-vacuum devices;
• high-vacuum modifications operate with low pressure, they use steam-oil mixtures; such a vacuum pump for a sewer truck has two connected superchargers;
• fore-vacuum devices form the appropriate range using mechanical blowers;
• low-vacuum type is used for low-pressure systems;
• Pre-discharge pumps are designed for operating situations in which it is necessary to reduce the pressure in the pumped medium to values ​​that can be handled by another vacuum pump.

Specifications

So that special equipment can effectively perform tasks, and operators do not complain to management that the pump on a sewage disposal machine does not pump well, it is important to pay attention to the following technical parameters of the pump:

• unit rotation speed;
• pumping speed;
• dimensions;
• starting pressure;
• outlet pressure;
• maximum vacuum pressure values;
• device compression ratio;
• residual pressure values;
• performance;
• weight.

Features of operation

To maintain the functionality and efficiency of the sewer machine, you should follow the following rules:

• before starting work, it is necessary to check the technical condition of the device;
• lower the hose into the sewer system;
• open the oil supply valve;
• turn on the pump;
• Upon completion of pumping, perform the same operations in reverse order.

“Always use high-quality new oil during operation, otherwise the pump will malfunction.”

The vacuum pump must be kept clean, since contamination is one of the common causes of breakdowns. Personnel must constantly monitor the oil level; with a minimum volume, the operating mode of the mechanism is disrupted. Most vacuum pumps can only run continuously for 1 hour before taking a break, as recommended by the pump manufacturer. It is advisable to regularly maintain the pump; this will extend its service life while maintaining its technical characteristics.

Popular modifications

Vacuum pumps for sewerage work have been used since the 30s of the last century. Today's pumps are critically different from their predecessors, both in capabilities and design. In the Russian Federation, three models are mainly used:

• The vacuum pump KO 503 for a sewer truck has been used since the 50s of the last century, it has been tested in operation and has proven itself to be excellent. made in a cast iron body, the rotor moves to the right, is capable of pumping 250 m3/hour, maximum pressure - 6 nPa;

Vacuum pump KO 503

• model KO 505A is an improved version of the previous pump, with the same maximum pressure it is characterized by higher operational parameters, when working with it it is important to pay attention to work safety;
• the KO 510 device is the most advanced modification, its rotor can rotate in both directions, that is, the pump can be installed on a car with any engine, the pump creates the same pressure, but the efficiency and performance are much higher.

Maintenance and care

In conclusion, let's touch on the rules for caring for the device:

• The device must be operated in clean conditions.
• The case must not overheat above +80 degrees Celsius.
• During operation, the oil level must be monitored. Oil consumption: for the suction cavity - 24 drops per minute, for bearings - 12 drops.
• The lubrication system should be flushed periodically. During cleaning, you need to fill in clean oil of class K-19 or K-12.

Model KO-510 has proven itself well. The pump is quite reliable, and its operation is completely justified from an economic point of view. Another advantage is its simplicity, so even workers with not very high qualifications can use this pump.

Vacuum truck: history, characteristics, history

Sewage machine (sewage truck, vacuum machine) is a machine for vacuum cleaning of cesspools and sewer wells, transportation and subsequent unloading of waste. The machines are designed to work with liquid waste that does not contain hazardous or flammable substances.

The first vacuum sewage disposal machines were built in the pre-war years; their appearance was associated with the growth of cities and the complication of sewer systems. In the USSR, the first vacuum machines of the type TsN-8, TsN-12 and TsN-15 based on the GAZ-AA and ZiS-5 were put into production in 1939.

Classification and design of a sewage disposal machine

Sewage disposal machines are divided into three types according to their aggregation:

• On a car chassis;

Tractor trailer;

• Car trailer.

The basis of the machine is a tank (barrel), in the rear part of which there is a receiving hatch for connecting a receiving hose (sleeve). In the upper part of the tank there is a pipeline inlet from the vacuum injection system (vacuum pump) and a signal and safety device is installed that monitors the liquid level. The pump is driven by a gearbox or power take-off shaft, or by its own motor. The machine can use auxiliary components: hose storage boxes, hose drums, mini-cranes, etc.

The sewage disposal machine works as follows. The pump creates a vacuum in the tank, due to which liquid waste is sucked into the tank through the receiving hose. Waste is unloaded by gravity or due to excess pressure created in the tank by a pump.

Main characteristics of vacuum trucks

The main characteristics of the machines include:

• Tank capacity;
• Waste pumping depth;
• Time to fill the container;
• Working pressure in the tank (vacuum);
• Chassis characteristics - weight, speed, engine power, etc.

Today, vacuum trucks with a capacity of 2 to 13 cubic meters are manufactured. m, capable of pumping waste from a depth of up to 4 - 6 m, the standard vacuum value in the tank is 0.08 MPa (approximately 0.78 atm), the time for complete filling is within 4 - 8 minutes.

Main characteristics of pumps

Parameters characterizing the operation of a certain model of vacuum pump for pumping out sewerage:

• pumping speed. This is the amount of contents pumped out per unit of time. Determined in the inlet section of the receiving pipeline;
• maximum starting pressure. This parameter characterizes the maximum inlet pressure at which pumping will begin;
• maximum outlet pressure. This is an indicator of the pressure at the outlet of the equipment when the pump will still be able to pump out the substance at the rated speed;
• steam pumping device performance. In the process of pumping out liquid, the amount of vapor is calculated in weight units;
• maximum residual pressure. This is the theoretical value to which the operating pressure approaches under standard conditions;
• steam pressure is maximum. This is the highest value of steam pressure at the pump inlet. This indicator is taken into account when pumping steam;
• pump compression ratio. The indicator characterizes the ratio of the volume of gas compressed during its compression.
