How to choose water ring vacuum pump and water ring vacuum pumps can be automatically bibulous _

water ring vacuum pump has been widely used vacuum pump, also harvest a lot of praise in the industry. Many friends asked me how I also choose water ring vacuum pump and how to realize the automatic suction of water ring vacuum pump. Today is a you to explain.

water ring vacuum water pump model is how to choose?

1, try to select a lower speed specification

1. On the premise of achieve the same pumping water, should as far as possible choose low speed water pump. The consumption of large pump than smaller power, that is, efficiency is higher.

2。 In addition, the size of the water ring vacuum pump is larger due to the long blade ( The length of the flow) , the curvature of the fluid is small, streamline the approximate straight, fluid close to slow the flow of change, and the secondary vortex in fluid flow. Caused by covering energy loss is small.

2, considering the influence of water temperature

most of the supply water temperature range is 25 ° to 35 ° C C, so compared with the amount of gas in the technical documentation, should be appropriate to increase the number of pump.

3, the effects of inhaling resistance

layout of pipeline, should use coarser manner oil suction pipe, to reduce the resistance loss, and reduce the right-angle bend, in order to achieve the purpose of improving the efficiency of oil absorption.

4。 Choose positive pressure small exhaust

1. Should consider the increase of the exhaust pressure of reflux and pump chamber increase affects the quantity of pumping.

2。 Along with the increase of the exhaust pressure of the pump shaft power also increases, second-hand drive power should also be increased. Selection model, the reference test performance curve and the corresponding technical data, to fully meet the requirements.

how to realize the automatic water ring vacuum pump suction

1. Water storage, water ring vacuum pump can be placed in the vicinity, and the bottom of the barrel is slightly higher than that of water ring vacuum water pump nozzle; Also it can be built near the water ring vacuum pump pump chamber on one side. When leaving the pool, swimming pool slightly lower to form at the bottom of the reservoir. Use pipes to barrels ( Or pool) Connected to the pump body of water injection hole. Before closing, to fill the water in the bucket from the tap in the, to fill the water in the bucket. Next time to start the water ring vacuum pump, can be filled with water. This method is filled with water and easy to use.

2。 Engine exhaust vacuum filling method is used to remove small engine muffler, dedicated exhaust shunt equipment installation, use to remove waste in the working process of the engine, and took the time to air to make water ring vacuum pump produce certain vacuum degree. In operation, the first to start the engine, then press the exhaust steering handle to close the waste gas discharge outlet, and the exhaust fumes from the engine through the exhaust gas jet nozzle. Because of high and low pressure gas injection velocity, so the suction effect.

3, water ring vacuum pump water tank of water diversion method is in the vacuum pump before the installation of a cylindrical tank, the top of the cabinet put oneself in another's position is one and a half spherical projection, cabinet put oneself in another's position is in the middle of a suction pipe, the nozzle is below the height of cabinet put oneself in another's position of the lens barrel. The lower export connected to water ring vacuum pump oil pipeline. Used in a water tank, first from the water injection water mouth water, then close the water injection mouth saliva.

Anyone who has seen the latest pool cover drain pump water pump in operation cannot help but be impressed with how far the technology has progressed over the past few years.
