Working liquid and affect the water ring vacuum pump valve output reason _ constant mechanical and electrical equipment co. , LTD

water ring vacuum pump is used to require a certain vacuum degree of device, and is used to maintain the vacuum degree. At present, the device will still do not have enough output. Valve is the main influence factors, the height of the working liquid and temperature and coolant temperature. About the purity of the cooler, today we talk about the working liquid and valve affect the output of two aspects.

1, internal valve leakage

due to the material of the valve and valve grinding process and its product quality is poorer, therefore the closing of the valve is not strict. So, on the one hand, will affect the vacuum of the unit, results in the decrease of vacuum degree, on the other hand, will waste heat steam of the system, and thus reduce the production cost of the system. Increased. In the inner valve leakage inspection after a week of professional, competent inspection found that the main steam and before the main valve of steam door there is internal leakage. Found before the water ring vacuum pump design of reheat main steam valve is hydrophobic. Through the orifice plate, after the opportunity to directly enter the exhaust device. Therefore, when the machine is closed, before reheating main steam valve, the main steam pipe to grind and manual door installed on the steam pipe. It can effectively solve the problem of internal valve leakage, which can keep the output. Under normal circumstances, to avoid affect output efficiency, improve the production efficiency.

2, poor valve sealing effect

in the each end of the equipment, flexible vents all have their own valves. Their main purpose is to avoid the problem of inadequate cavity body compression, in order to ensure the work efficiency of the whole equipment. The state of the valve is designed to make the lower end of the valve close to the equipment section, and the upper is 'S' shape. However, such a design can cause stress accumulation after long time use, this is likely to lead to rupture disc injury. Under normal circumstances, if one side of the valve is broken, and the temperature will suddenly fall in trachea, and water ring vacuum pump equipment will be shaking. If both sides of the valve plate fracture at the same time, will lead to vacuum decline, so that the energy consumption of the sudden increase.

1, the working fluid temperature

the working temperature of water ring vacuum water pump pump body has a great influence on the process operation also. Usually, when the water temperature is too high, will lead to sudden high steam pressure in the pump body, thus it is impossible to ensure sufficient water ring vacuum water pump pumping quantity. Therefore, is bound to lead to a large number of air accumulation in the condenser, leading to unable to ensure good heat dissipation effect, resulting in sharp decline in vacuum, back pressure significantly increased. Therefore, keeping the temperature of pump body in the appropriate scope is the basic factor to ensure the normal working efficiency. In general, the factors that affect the working liquid pump body temperature are: the purity of the cooler, the steam from the steam and cooling water temperature, so the equipment need to pay special attention to whether there is in the process of the operation whether there is abnormal, please clean up after the operation.

2, working liquid level too high

according to the requirements of process design of water separator, liquid level typically take within a reasonable range. If you add too much liquid, the liquid level is too high, it is easy to cause the clogging in the drainage of water ring vacuum pump core, thus affecting the water ring vacuum pump. The operation result. Suction when they enter the working state, the gaseous mixture may be condensing, result in higher level. At the same time, the water inlet valve will automatically close the lock, and then the internal water vapor will flow from the overflow tube. Was released from the hospital. When pump the liquid level is too low, the formation of the annular water ability is insufficient, can't guarantee the normal work of the compression and inhalation, which affect efficiency. When this happens, water ring vacuum water pump water inlet valve will open automatically, and before the stop, the interior of the separator will be filled with water to fill the specified level.

these are working liquid of water ring vacuum pumps and valves of two aspects. Internal valve leakage will lead to low output, and valve sealing effect will be very poor, resulting in low output. Job level is too high, fluid temperature is too high. In fact, when the equipment operation, will inevitably under the influence of some components. We need to carefully carefully to find the reason.
