Embodiment 1

[0042] Such as figure 1 It is a schematic diagram of a non-isolated multi-type piston accumulator combined with gas and oil tanks. It consists of oil tank 1, oil tank bracket 2, air tank 3 and high pressure ball valve 4. The part of the oil tank 1 is provided with an oil tank support 2, a high-pressure ball valve 4 is arranged above the oil tank 1, and an air tank 3 is arranged above the high-pressure ball valve 4 and is connected with the flange 7 on the gas tank 3. The oil tank 1 has an oil tank structure with a magnetostrictive displacement sensor and an oil tank structure with a magnetic induction proximity switch. The gas tank has an inverted mountain shape, an annular two-body seat type, an annular four-body seat type and a T-shaped structure. They can be combined into eight types of piston accumulators with different capacities.

[0043] Such as figure 2 As shown, the air container 3 is an inverted mountain-shaped air container, including the air container body...

Embodiment 2

[0047] The difference between this embodiment and Embodiment 1 is that this embodiment adopts a schematic structural diagram of an oil tank with a magnetic induction proximity switch, as shown in Figure 4 As shown, most of its structure is the same as image 3 The oil tank with a magnetostrictive position sensor is the same, the difference lies in the relevant parts caused by the installation of the magnetic induction proximity switch 32, which is described as follows; the top of the aluminum alloy piston 27 is provided with a proximity switch trigger body 18, and the connector 11 is connected to the oil tank. Near the contact of 14, a magnetic induction proximity switch 32 is provided, and a magnetic induction proximity switch 32 is also installed on the oil tank seat 25. The guide shaft at the bottom of the aluminum alloy piston 27 also acts as a trigger body for the proximity switch. When the oil and replenishing oil are full, a signal is sent, and the magnetic induction p...

Embodiment 3

[0050] Such as Figure 5 and Figure 6 As shown in , it is a schematic structural diagram of a non-isolated low-pressure-difference inverted mountain-shaped piston accumulator combined with gas and oil tanks. Including the gas tank 6, the lower part of the gas tank 6 is welded with an inherent spherical head 6-3, the bottom of the spherical head 6-3 is provided with a sewage outlet 6-4, and the upper part of the gas tank 6 is provided with a first flange 7- 1. A different-diameter elbow 8 is provided above the first flange 7-1, a seamless steel pipe 9 is provided on the side of the different-diameter elbow 8, and a different-diameter tee 10 is provided on the side of the seamless steel pipe 9 , a flange 7 is provided at the lower part of the reducing tee 10 trails. Other structures and working methods of this embodiment are the same as those of Embodiment 1.

Abstract

The invention provides a gas and oil canister combined non-isolated multiple piston accumulator, which is characterized by comprising an oil canister, and a high pressure ball valve and a gas canister on the oil canister; and the oil canister side is provided with an oil canister support. Various standard components are welded to form the large capacity gas canister, and the gas canister is connected with the oil canister into an integral multiple accumulator with a compact structure; oil exists on two sides of a piston in the oil canister, so the accumulator becomes an isolated (the piston isolates the oil and gas) and non-isolated accumulator in which the gas canister saves a little oil and gas directly contacted; a guiding sliding sleeve of the piston is provided with a plurality of inclined oil grooves facilitating lubricating; nitrogen inlet and outlet are provided with magnetic filters for absorbing magnetic pollutants; and two types of piston position detection and control devices are arranged. The gas and oil canister combined non-isolated multiple piston accumulator has the advantages of large capacity of gas canister and oil canister, multiple function, low pressure difference, quick response, simple and compact structure, flexible and convenient operation, adjustment and maintenance, and signal prompt and control for oil leakage and oil supplement.

Description

technical field [0001] The invention relates to a non-isolated multi-type piston accumulator combined with an air and oil tank, which is used in a hydraulic system and belongs to the technical field of accumulators. Background technique [0002] Accumulators are widely used in some hydraulic systems, and are also important accessories in hydraulic systems. They play an important role in the normal operation of the system, shock resistance, auxiliary energy, energy saving, etc., and are already very mature, reliable and widely used products. At present, more accumulators are used, mainly bladder-type accumulators and piston-type accumulators, each of which has its own advantages and disadvantages, as well as limitations and applicable scopes and occasions. The piston type accumulator has the advantages of large capacity, long service life, simple structure, simple and easy installation, convenient maintenance, small workload, reliable operation, and stereotyped products.
