Ultra-high molecular polyethylene gear pump

Abstract

The invention relates to an ultra-high molecular polyethylene gear pump, which is composed of a pump body with an ultra-high molecular polyethylene material, a driven wheel, a gland, a main wheel body with a metal material and the like. A driving wheel is positioned on a boss of the pump body, and is engaged with the driven wheel, the wall of the driven wheel can be thickened properly, the boss, a crescent shaped lever and the pump body are combined as an integral body, a manufacture method can employ a machine tooling device to process and shape, or employ a molding and sintering process. The pump body, the driven wheel, the gland and the driving wheel are in soft and hard duality relation, and can preventing the driving wheel from damaging, the ultra-high molecular polyethylene gear pump has the excellent performances of wear resistance, health and nontoxicity, vibration and noise reduction and no adhesion, and is suitable for the gear pump delivered by the high viscosity liquids, foods, medicines and chemical mediums. The ultra-high molecular polyethylene gear pump has the advantages that the components of the ultra-high molecular polyethylene material can replace the metal material components in the prior art, the service life of the gear pump can be increased, the ultra-high molecular polyethylene gear pump has the active effects of no pollution, no vibration, no noisy, self-cleanness, simple treatment and the reduced cost.

Description

technical field [0001] The invention belongs to the technical field of hydraulic equipment, and in particular relates to a gear pump in which a pump body, a driven wheel and a gland part are made of ultra-high molecular polyethylene. Background technique [0002] The gear pump is an ideal equipment for conveying high-viscosity liquid. It has a simple structure and small size, and is widely used in various fields of hydraulic systems and liquid conveying systems. The gear pump is composed of a driving wheel and a driven wheel, and the two gears have the same modulus. In the closed pump body, the two gears are closely matched with the pump body. The position of the gears is the working area of ​​the pump body. The transmission medium enters from the inlet, and with the rotation of the gears, the medium is discharged from the outlet, and finally The pressure of the medium is converted into mechanical energy to do work. [0003] A gear pump is also called a positive displacemen...
