Device for increasing drainage volume of immersible pump

Abstract

The invention discloses a device for increasing the drainage volume of an immersible pump. The immersible pump is fixed in a reservoir. An immersible pump water inlet, an immersible pump cavity and an immersible pump water outlet of the immersible pump are lower than a working water level of the reservoir, and an opening of the immersible pump water outlet faces a sleeve. The sleeve is fixed to the upper portion of the immersible pump. The sleeve comprises a sleeve water inlet pipe and a sleeve water outlet pipe. The immersible pump water outlet is sleeved with the sleeve water inlet pipe, and the outer diameter of the top end of the sleeve water inlet pipe is smaller than the inner diameter of the water inlet end of the sleeve water outlet pipe, so that a water inlet of the sleeve is formed between the top end of the sleeve water inlet pipe and the sleeve water outlet pipe. The water outlet of the sleeve water outlet pipe is higher than a water outlet of the sleeve of the working water level of the reservoir. As for the device, through the double-superposition effect of water in the reservoir, the drainage volume of the immersible pump is greatly increased, and the purposes of saving electricity, reducing the occupied space of a pump body and reducing the cost of the immersible pump are achieved.

Description

Technical field [0001] The invention relates to a device for enhancing drainage flow, in particular to a device that uses a submersible pump to enhance drainage. Background technique [0002] In real life, people are increasingly using submersible pumps to meet various water needs. As we all know, the use of submersible pumps often choose the pump body with suitable head and drainage flow according to the actual application. In places where the drainage flow demand is large, a submersible pump of higher power is often selected to meet the drainage flow requirements. The use of high-power submersible pumps not only has the problem of energy consumption, but the excessive space occupation of the pump body also limits the use of high-power submersible pumps. [0003] Because of its beauty and space saving, intelligent toilets without water tanks or ultra-low water tanks are becoming more and more popular. The conventional method of flushing such toilets on the market is to use tap w...

Problems solved by technology

The use of high-power submersible pumps not only has the problem of energy consumption, but also the excessive space occupied by the pump body also limits the use of high-power submersible pumps.

[0003] Because of aesthetics and space-saving reasons, intelligent toilets without water tanks or ultra-low water tanks are becoming more and more popular. The current conventional flushing method for such toilets on the market is to use tap water to directly enter the toilet for washing and flushing through solenoid valve control, but tap water The biggest problem with direct flushing is that when the water pressure of the tap water pipe is lower than 0.25Mpa, sufficient water pressure and flow cannot be guaranteed, and the cleaning and flushing effect of the toilet is very poor, and the proportion of residents whose water supply pressure is lower than 0.25Mpa is still quite large Therefore, when toilet sellers sell this type of toilet, they have to come to the door in advance to measure the actual water supply pressure in the customer's home to determine the applicability

In addition, even when the water pressure of the residents’ water supply is guaranteed, due to the uncertainty of the water pressure of each user and the randomness of the water pressure fluctuation during peak water consumption, the amount of flushing water cannot be accurately set and controlled, resulting in a certain degree of waste of water
