Problems solved by technology

The longer the conveying distance, the higher the conveying height, and the greater the conveying pressure, the more serious the material backflow and the lower the conveying efficiency
[0004] 2. When transporting bulk materials such as stones upward, the pulsation of flow and the backflow of materials will cause the bulk materials such as stones to move downward due to vibration and impact and form accumulations, which will further cause the blockage of the conveying pipeline
[0005] 3. The pulsating pressure will cause pressure shocks to the pumping equipment, conveying pipelines and pipeline valves, and the material flowing back in the pipeline will produce greater impact due to the water hammer effect when it suddenly stops or changes direction, making the Pumping equipment, delivery pipelines

Abstract

The invention discloses a double-cylinder flow stabilizing delivery pump. The double-cylinder flow stabilizing delivery pump comprises a pumping hydraulic pump, a fast reverse hydraulic pump, a fast reverse hydraulic valve bank, a pumping hydraulic valve bank, a distribution valve bank, a pumping hydraulic cylinder A and a pumping hydraulic cylinder B. The pumping hydraulic cylinder A is connected with the pumping hydraulic cylinder B in parallel and communicates with the pumping hydraulic cylinder B. A communication cavity of the pumping hydraulic cylinders is connected with the fast reverse hydraulic valve bank. The fast reverse hydraulic valve bank is further connected with the fast reverse hydraulic pump and an oil return pipeline. The pumping hydraulic valve bank is connected with a non-communication cavity of the pumping hydraulic cylinder A, a non-communication cavity of the pumping hydraulic cylinder B, the pumping hydraulic pump and the oil return pipeline through an oil circuit. The reciprocating type double-cylinder delivery pump is stable in pressure and flow, high in volume efficiency, not prone to pipe blockage, small in pipeline vibration, safe, reliable and wide in applicable range. The invention further discloses a trailer pump and a pump truck adopting the double-cylinder flow stabilizing delivery pump.

Description

technical field [0001] The present invention generally relates to the field of pumping equipment, in particular to a double-cylinder steady-flow conveying pump for pumping materials such as liquids, slurries, pastes, and paste-like materials, and a drag pump using the double-cylinder steady-flow conveying pump and pump trucks. Background technique [0002] The pipeline conveying equipment for conveying slurry, paste or paste-like materials such as slurry, concrete, coal slime, municipal sludge, printing and dyeing sludge, chemical sludge, liquid food raw materials mainly includes ball valve conveying pumps and seat valve conveying Pump, gate valve transfer pump, S-pipe valve transfer pump, C-shaped pipe valve transfer pump and skirt valve transfer pump and other double-cylinder transfer pumps. These transfer pumps work in the way of double-cylinder alternate suction and pumping. In the process of switching between suction and pumping, there are changes in pumping pressure a...
