Low reliability vibration pumps for water. Tips producers

A lot of time that could be devoted to the basic work - construction of the fence, goes to regular maintenance of the vibration of the pump, which pumps the well. It's been almost a month. In the pump every evening, and on weekends full day. But the water with sand keeps going. Because sand as an abrasive and works to pump harder to raise this water - a part wear out. Regularly lift and climb the pump, two pick one.

Reclaimed water for more than 1m3 different sand fraction. The mixture is more like a sandy loam.

Replacement of the axis on which rests the whole system with the piston and the membrane. Washers triturated for the second axis. First brewed brother - made jewelry. Repair Cost - $ 0.

Washers "ate" that's axis is for this reason:

Grind off the piston sleeve, lining washer lost abutment and freely vibrated motion, rubbed axis. In the last repairs instead put the nut. This axis is again necessary to weld and grind.

What brands of pumps in operation - reported here

In the process of repair (as assembled and disassembled the pump, have probably a dozen times), I concluded that in this design laid premature wear of parts. When working in clear water it will affect a couple of years, but in the water with sand and slurry - just a week of daily work.

Yes, nothing is eternal and trusted already do, or a certain type of product will stop regular purchase and production will be unprofitable, the amount produced will decrease because of the demand and profits fall. We'll have to raise prices, which will lead to a decrease in purchasing power. A vicious circle of wild capitalism. Look at the subject documentary "Buy, throw, buy" - it's all very well shown.

But it is, speculation. What could be done by the manufacturer for a long-term operation of the vibration of the pump?

1. Is securely fixed to the piston axis. Not simply press the nut sleeve on which is fixed the rubber piston and the sleeve axis must be wound on and fixed nut. Axis would have made thicker in the area of ​​the piston.

1. Contributed to the design of the opportunity to change the water inlet assembly into the pump. And do not entirely cover during wear. Holes "gnaws" sand and the valve stops working (this photo is contained in previous articles). It is possible to place the entrance of water to make an iron alloy and fasten it to the lid through a pad of silumin. Iron will not wear out like a soft aluminum alloy.
2. Needed rubber "jacket" on the body. Pump vibrates in an iron tube wells, rubs against the wall and her body is cleared. I read on forums that some over the years wear on the body reached before the opening.

This basic. Even such a structure can be termed as a modernized version of the pump is for pumping wells with sand. Even though it will cost more, but if the service life will increase many times in such conditions, it is possible to overpay. Even in clear water it will run several times longer.

In general, if someone from representatives of producers reading this - listen. The idea of ​​expanding the range of data available to the two pumps: with upper and lower water intake.

The very well pumping continues. But, in spite of the daily process - it pulled a lot of sand and clay, a few meters. In any case, drillers called to ask how much it will quickly clean the hole from the sand. A: 19 thousand. rub. Price inadequate. While I was pumped, but we'll see.

I can not help but show and pleasant, "tasty" photos with partially assembled timber harvest strawberries and strawberry right on the site:

Strawberries. As previously I wrote - strawberry cultures like the soil of this land. They spread like weeds, forcing dandelion. Plantation forest strawberries and strawberries grown to 2 acres. In the evening, when there is time to pick berries.

Forest strawberries this year, particularly large - with large peas. A few berries - almost like a garden strawberries. The aroma and taste of the forest entirely different.
