The float switches are small gray devices that float in the sewage tank and detect the rising levels of the waste collected. The float switch in the sewage pump can get spoiled and stop working over a period of time.

To prevent this clogging and eventual breakdown of the ejector pump system, professional cleaning and removing the residue waste is required every few years.They can accumulate and cover up everything thus blocking the normal flow of waste water, thereby stopping the ejection of waste water out of the system. The grease sticks to the plumbing and sewer pipes. Over the years, the waste collected in tanks deposit a lot of grease.

Some common problems that can occur in ejector pump systems are mentioned below: If your ejector pump system repair time has come, call us for our excellent services in Maryland. Many models of ejector pump systems come with a sensor that sounds when the pump breaks down, indicating to the owner that it is repair time. The ground waste moves out of the tank and flows into the plumbing pipes and takes waste out to the main sewer lines.

The tank is filled with sewage and when it reaches a certain limit, the float which rises along with the waste indicates the pump to start grinding the waste. An ejector pump system consists of a pump, float, inlet, outlet, and a tank. It is the most suitable equipment in hazardous areas like steam generation systems, crude oil distillation, thermal power plants, petrochemicals, fertilizers, deodorization of oil, degassing of metal vacuum, etc.An ejector pump system shreds the waste into finely-ground particles and water slurry which can easily be pumped out to the desired destination of disposal.It can be mounted anywhere on the device. Ejectors usually don’t have space issues due its lightweight and easy handling.Ejector eliminates the chances of fire or explosion as there are no moving parts in it.It helps to provide continuous flow through suction media.Due to the multiple nozzles, it is used to reduce the steam consumption by 9-17 % as compared to the single-stage ejector and thus it is more efficient. In addition to this, the initial cost is high and the evacuation time is very short. On the other hand, multi-stage ejectors give high suction flowrate and generate low noise.It is mainly used to achieve high compression ratios. It is preferred in one set of design condition due to its single nozzle. It is used in critical as well as non-critical flow conditions. Also, the evacuation time is short and the noise generation is high. In the case of single-stage ejectors, the suction flow is average and the initial cost is low due to single and compact nozzle.

Steam jet ejectors are used, when motive fluid is water. It provides high vacuum level with small flowrate.

Steam jet vacuum ejectors can be used to remove the gases and vapor generated during the process and generate vacuum in the reactor (refer the image which has mounted ejector on the vessel).

Vacuum jet ejectors used motive fluid as compressed air.

In the case of vacuum jet ejectors, due to their static and compact structure, there will be less wear and tear.

In this way, waste gas (flare gas) can be recovered and added to the production.įigure 5 : Steam Jet Ejector mounted on Vessel As motive fluid flows through a nozzle, it expands at high pressure and reduces the velocity of the fluid. It is accomplished through adiabatic expansion from the supply pressure of the motive fluid to the suction pressure load created in the suction chamber.

In general, ejectors convert the pressure energy (potential energy) of the motive fluid to velocity energy (kinetic energy).

Once the motive fluid passed through the nozzle, due to a change in cross sectional flow area (cone shape after nozzle), the compressed fluid slows down and the recovered gas obtained in suction chamber will be discharged with the help of a diffuser (yellow arrow fig 4). During the process, motive fluid is compressed and accelerated. Afterward, it is passed through the nozzle.

Motive fluid is provided through the inlet (yellow arrow in fig.4) of the ejector and the low pressure flare gas from the process vessel or reactor (yellow arrow fig.

Motive fluid can be anything that further can be compressed by ejector.
