Embodiment 1

[0036] This embodiment is a split type large water hammer pump, such as figure 1 shown. This embodiment includes: a power pipe 1, the power pipe is connected to the pump body fixed on the foundation 2, the pump body is connected to the elbow 3, and the bottom of the vertical water inlet pipe 4, and the water inlet pipe is connected to the water delivery valve 5 connection, the water delivery valve is provided with a spring limit facility 6, the water delivery valve is connected to the air tank 8 fixed on the foundation with the water pumping pipe 7 through a connecting pipe, the connecting pipe is A detachable telescopic joint 9 is provided, and the air tank is provided with an air supply facility 10, and the elbow is connected to the small end of a different-diameter pipe 11 with one end large and the other end small, and the large end of the different-diameter pipe The end is connected with the drain valve 12, and the drain valve disc of the drain valve is provided with a d...

Embodiment 2

[0047] This embodiment is an improvement of the first embodiment, and it is a refinement of the first embodiment on the spring limit mechanism on the water transfer. The spring limiting mechanism described in this embodiment includes: a valve stem 601 fixed at the center of the valve disc, and a sleeve 602 fixedly connected with the valve seat is sleeved on the valve stem. A spring 603 is set, and the valve stem is provided with a limit block 604 that limits the excessive compression of the spring, such as figure 2 shown.

[0048] Limiting the compression and release length of the spring to prolong the service life of the spring is the main purpose of using the spring limit mechanism. The biggest difficulty in manufacturing a large water hammer pump is how to prolong the service life of the drain valve and water delivery valve of the water hammer pump, so that these two valves can work for a long time without damage. The spring limiting mechanism adopted in this embodiment ...

Embodiment 3

[0051] This embodiment is an improvement of the above embodiment, and is a refinement of the above embodiment on the expansion joint. The expansion joint described in this embodiment includes: an inner 901 and an outer sleeve 902 that can slide and expand each other, a sealing ring 903 is provided between the inner and outer sleeves, and the inner and outer sleeves are connected to their respective docking flanges 904, 905 connection, such as image 3 shown.

[0052] There are many forms of telescopic joints, and this embodiment only enumerates one of them. In this embodiment, two casings which are nested together and can move with each other are used, and a sealing member is arranged between the two casings so that the sliding surfaces of the two can be sealed. Since the sliding surface only slides during installation, there is no dynamic sealing problem, and the general O-ring can achieve a good sealing effect.

[0053] Different from the traditional water hammer pump des...

Abstract

The invention relates to a split-type large water hammer pump and a starting method thereof. The split-type large water hammer pump comprises a power pipe, a bent pipe, a vertical water inlet pipe, areducing pipe, an air tank pipe, a water conveying valve, a connecting pipe and a water escape valve. The water conveying valve is equipped with a spring limiting facility. The connecting pipe is provided with detachable telescopic joints. An air tank is provided with an air supplementing facility. A water facing surface of a water escape valve clack is equipped with a flow guide body fixedly connected with the reducing pipe. The water escape valve is provided with a lever or a hydraulic opening mechanism. By arranging the flow guide body on the water escape valve, the mass of the water escapevalve clack is reduced. Therefore, an impact resistance problem of the water escape valve is resolved. The water conveying valve is provided with a limiting mode so that service lifetime of a water-conveying valve spring is prolonged. By arranging the starting mechanism, the problem that a conventional mode fails to start a large water hammer pump is resolved. The telescopic joints help resolve problems related to installation, transportation and maintenance of the large water hammer pump. Due to the air supplementing facility, the air tank is not excessively large. The water hammer pump canbe used in a large-scale hydraulic project, which saves a great deal of petrochemical energy.

Description

technical field [0001] The invention relates to a split-type large-scale water hammer pump and a starting method, and is a hydraulic facility and a starting method, and is a large-scale hydraulic machinery and a starting method. Background technique [0002] The water hammer pump is an automatic water pumping machine, which uses the power of flowing water to periodically and automatically generate a water hammer effect to lift water from a low place to a high place. Different from conventional water pumps, the pumping power of the water hammer pump comes from the water itself, and does not require other energy sources such as coal, oil or electricity. It is an environmentally friendly pumping equipment. [0003] Existing water hammer pumps can all be regarded as "small" water hammer pumps, the diameter of the water outlet is generally 20-30 cm, and the power is only a few hundred watts. With a diameter of 50 cm and a power of more than one kilowatt, it is considered a large...
